    Description of Embodiments Hereinafter, embodiments of the present invention will be explained with reference to the accompanying drawings.
    (Embodiment 1) F ig. 1 is a schematic view of a construction machine or work vehicle with a monitoring device for a work vehicle (hereinafter simply referred to as "monitoring device") according to Embodiment 1 of the present invention. A construction machine S shown in the figure is a hydraulic excavator and comprises a chassis 1 having a caterpillar track or the like, an upper pivot body 3 which is rotatably mounted on an upper part of the chassis 1 via a turning mechanism 2 and a work tool 4 which is connected to the upper rotating body 3. The working tool 4 comprises a cantilever 5 whose base part is rotatably coupled to the upper rotating body 3, an arm 6 which is rotatably coupled to the leading edge of the cantilever 5 and a bucket 7 which is rotatably coupled to the leading edge of the arm 6. The upper torque also includes a cab or the like.
    Fig. 2 is a perspective view showing an internal configuration of the cab 8. As shown in Figs. 2, the driver's cab 8 comprises a driver's seat 9 in the central part and is provided with a drive unit 10 in front of the driver's seat 9. This drive unit 10 comprises control levers 11 and 12 and control pedals 13 and 14 which are rotatably integrated with the control levers 11 and 12. When the operator the control levers 11 and 12 forwards move the chassis 1 forwards, while when the operator pulls the control levers backwards, the chassis 1 moves backwards. An additional pedal 15 is arranged near the drive unit 10. An instrument panel 17 is also arranged near a right side window 16 in Fig. 2.
    In the right and left part of the driver's seat 9, the respective tool levers 18 and 19 are installed. The tool levers 18 and 19 perform an up-and-down movement of the cantilever 5, rotation of the arm 6 and the bucket 7, rotational movements of the upper rotating body 3, and so on. Furthermore, a locking lever 20 is arranged close to the work tool lever 18. The locking lever is used here to stop functions such as driving the work tool 4, turning the upper turning body 3 and movement of the chassis 1. By pulling up the locking lever 20 it is thus possible to lock (ie prevent ) a movement of the work tool 4 or the like. In a state where the movement of the work tool 4 or the like is locked by the locking lever 20, the work tool 4 or the like is not operated even if the operator operates the work tool levers 18 and 19 or the like.
    In the lower part of a vertical frame 23, which separates a front window 22 from a side window 16 in the cab 8, a monitoring device 21 is arranged, which for example shows an engine condition of the construction machine S. The engine condition is stated here, e.g. a temperature of the engine cooling water, a temperature of hydraulic oil or the remaining amount of fuel and the like.
    Fig. 3 is a schematic diagram showing a configuration of a control system of the construction machine S. As shown in Fig. 3, the control system of the construction machine comprises a first hydraulic pump 3a, which injects a pressure oil to generate an oil pressure to drive the work tool 4. or the like, and a second hydraulic pump 31b, which injects pressure oil to produce an oil pressure corresponding to the operation of the work tool levers 18 and 19. A drive unit for a thumb disk 32 is operated based on an instruction from a pump regulator 33 and changes the angle of inclination of the inclined disk. first hydraulic pump 3 la. A hydraulic actuator 35 is connected to the first hydraulic pump 3la via a control valve 34.
    The hydraulic actuator consists, for example, of a cantilever cylinder, an arm cylinder, a bucket cylinder, a rotatable hydraulic motor, a driving hydraulic motor and the like.
    The work tool lever 18 (19) and the locking lever 20 are also connected to the second hydraulic pump 31b.
    The control system S of the construction machine S further has an engine 36 having a drive shaft coupling the first hydraulic pump 31a and the second hydraulic pump 3lb, a common rail 37 which adjusts the amount of fuel from a fuel supply device in the engine 36, and an engine regulator 38 which controls the operation of the engine 36 The engine 36 is a diesel engine. The engine rotation speed of the engine 36 is determined by a fuel gauge 39, and the actual engine rotation speed is sensed by a rotation sensor 40. The engine controller 38 controls, for example, the fuel supply amount in the fuel supply unit based on, for example, a control signal from a lever from the driver. etc. The pump regulator 33 performs checks so that the first hydraulic pump 31a absorbs the best matching torque at each discharge point of the engine 36, which is based on the torque of the pump absorption set for each mode of operation of the construction machine S, the engine rotation speed set in the fuel gauge 39 and the actual engine speed. working methods here, it is possible, for example, to set a "heavy excavation permit", which can maintain a large value of the workload corresponding to the amount excavated per unit of time, or a "fuel-saving permit" that further reduces fuel consumption during light load work.
    A control key 41 is connected to the motor controller 38, where the control key inputs a key activation signal and key activation signal to instruct the activation or deactivation of the motor operation. The control key 41 is useful when: a key is inserted into a so-called key cylinder to generate electrical signals (i.e. key activation signal and key activation signal) by a rotating operation; the electrical signals are generated when verification is given using an electronic key with a latch; or the electrical signals are generated by a push button.
    A PPC control lock 42 is connected to the locking lever 20. When the locking lever 20 is operated to the locking side, the PPC control lock 42 senses the operation and sends a signal to a valve (ie an electromagnetic valve) 43. In this way it is possible to stop functions such as an operation of the work tool 4, a rotation of the upper rotating body 3 and a movement of the chassis 1. At this time the motor has a low rotational speed, idling.
    Fig. 4 is a block diagram showing a functional configuration of the monitoring device 21 and a configuration of control system elements with respect to the monitoring device 21. The monitoring device 21 comprises an input unit 201 in which a driver or service personnel enters various instructions and information, a display unit 202, which displays various types of information including information relating to operations of the construction machine, and a controller 203 as a display control unit which controls operations of the monitoring device 21. The display unit 202 has a function which sequentially updates and displays the current contents of a monitoring object selected from a number of monitoring objects that have to do with the operating permit of the construction machine. The monitoring device 21 further comprises an IC clock 204, which has the function of determining the key activation or key activation time, a signal detection unit 205, which detects a signal input from the control key 41, and a memory 206 as a storage unit, which uses an EEPROM or the like for storing e.g. the number of monitoring objects relating to the operating state of the construction machine, information input through the input unit 201 and a program for operating the monitoring device 21. The monitoring device 21, having the above-mentioned configuration, is connected to e.g. a number of sensors 44a, 44b, etc., which include a temperature sensor senses the air conditioning temperature in the cab 8 of the construction machine S and actuators 45a, 45b, etc. are designed to perform operations corresponding to the results detected in the many sensors 44a, 44b, etc.
    The motor controller 38 includes a rotation sensor 40 and a temperature sensor which senses the water temperature of the engine cooling water and is connected to a number of sensors 46a, 46b, etc., which sense the engine drive state and actuators 47a, 47b, etc. which drive the engine based on the results of the many sensors 46a, 46b, os v.
    The actuators 47a, 47b, etc. include a control motor 37.
    The pump regulator 33 is connected to a plurality of sensors 48a, 48b, etc. which include a compression sensor which senses the oil pressure in a predetermined position in a hydraulic circuit which includes the first hydraulic pump 31a and the second hydraulic pump 31b, and a plurality of actuators 49a, 49b, etc. which controls the operation of the work tool 4 based on the results of the many sensors 48a, 48b, etc. The many actuators 49a, 49b, etc. include an actuator which adjusts the angle of inclination of the first hydraulic pump 3a and a cantilever cylinder, an arm cylinder , a bucket cylinder, a rotatable hydraulic motor and a driving hydraulic motor forming the hydraulic actuator 35. 8 F ig. 5 is a diagram showing an appearance configuration of the monitoring device 21. The input unit 201 is provided with a number of buttons, as shown in Fig. 5. In the input unit 201, functional buttons F1 to F6 are located below the display unit 202 and shown as "F1" to "F6". "Switch for input signals corresponding to the icons shown above the switches, on the display unit 202. Below the functional switches F1 to F6 there is: an automatic deceleration button which performs automatic deceleration control to reduce the rotational speed of the motor when the implement levers 18 and 19 are again in neutral positions ; an operating state selection button 212, which selects an operating state for the construction machine S from a plurality of operating states; a current speed level selection button 213, which selects the drive speed level of the construction machine S from a plurality of drive speed levels; a buzzer lifting button 214, which lifts buzzer tones which are generated when the construction machine S is in a predetermined warning position; a wiper button 215, which controls a wiper (not shown) on the windscreen of the cab 8 (see Fig. 5); a wash button 216, which controls a washer (not shown) to spray wash water on the windshield; and an air conditioning button in the cab 8. As input unit 201, a touch panel, such as a resistance film system, is equally applicable here.
    The display shown in Fig. 5 of the display unit 202 indicates a standard display shown during normal operation of the construction machine. "Normal operation" here indicates a work at the time when the construction machine performs machining.
    When the construction machine is, for example, a hydraulic excavator, it is meant that normal operation at the time is work when machining, such as excavation, is carried out.
    The standard display 101 shows at least one of an engine water temperature gauge G1 indicating the water temperature of the engine cooling water, an operating oil temperature gauge G2 indicating the operating oil temperature in the hydraulic circuit and a fuel level gauge G3 indicating the remaining fuel amount level. Furthermore, a fuel consumption meter G4 is displayed on the right side of the fuel level meter G3. A clock W is arranged in the upper, central part of the display unit 202. To the right of the clock W, an operating state icon IM, which indicates a set operating state, and a driving speed level icon 15, which indicates a set, running speed level, are arranged.
    On the standard display 101, the character "P" is displayed as the operating status icon IM. This corresponds to the display of a case where the operating condition is set to heavy excavation condition. In contrast, when the construction machine S is set to the fuel-saving state and the character "E" is displayed as the operating state icon IM.
    The standard monitor 101 also displays an icon including the character string "Hi" as the travel speed level icon IS. This icon indicates a reading in a case where the driving speed level is set to high speed. The driving speed level selection and input, via the driving speed level selection button 213, includes three types of low speed, medium speed and high speed. When the low speed is selected from these, an icon containing the character string "Lo" is displayed as the travel speed level icon IS. When the average speed is selected, an icon containing the character string "Mi" is also displayed as the travel speed level icon IS.
    In the positions below the standard display 101 but above the function buttons F3 to F6 there are arranged guide icons l1 to 14, which respectively correspond to the function buttons F3 to F 6. Among these, the guide icon II indicates an icon indicating that a display shown by the display unit 202 is switched to a camera display. The camera screen indicates a monitor with output from a camera such as a CCD camera (not shown) which is arranged on an external part of the construction machine S and depicts the environment outside the construction machine S.
    The guide icon 12 further indicates an icon indicating that the display of the clock W is switched to the display on a service meter. The guide icon I3 further indicates an icon indicating that the monitor displayed by the display unit is switched to a monitor for a maintenance condition to perform maintenance. The guide icon 14 further indicates an icon indicating that the display displayed by the display unit 202 is switched to a display for a user state to adjust the brightness and set the clock. Therefore, when, for example, the function key F3, corresponding to the guide icon II, is pressed to input a signal, the controller performs control by switching the monitor shown by the display unit 202 and showing, for example, a camera monitor on the rear of the construction machine depicted with a camera mounted on the outside of the construction machine.
    Fig. 6 is a diagram showing the display contents displayed by the display unit 202. In the display unit 202 it is possible to switch the standard display 101 to a display for a user menu 102 to set settings of a general user (ie an operator operating the vehicle) or a service menu screen 103 for performing manager settings. "Manager" here refers, for example, to a manager of a rental company for the construction machine or service staff at a supplier representative for the construction machine. The switch from the standard monitor to the monitor for the service menu is performed here via an entry of a password that is not known to the general user and an execution of a special procedure. Thus, it is desirable to set settings so that the general user can not switch to the service menu screen 103.
    In the screen for the service menu 103, the manager can display a menu that is necessary to perform error assessments and defect analyzes. To be more specific, the examples of displayed menus include "monitoring" to display a detected result of objects selected from objects detected by various sensors connected to the monitoring device 21, the motor controller 38 or the pump controller 33, "error history" showing the history over errors, "maintenance history" showing the history of maintenance, "maintenance settings" for performing maintenance settings and "initial value settings" to set the occurrence and non-occurrence of optional properties and the initial values for monitoring. Among these, the monitoring objects selected in the monitoring menu include "engine rotation speed", "engine water temperature", "remaining amount of fuel" and the like shown in Fig. 6.
    Fig. 7 is a diagram showing a screen transfer example when using the monitoring device 21 in performing the monitoring. When the supervisor performs monitoring, the "monitoring" menu is first selected from the screen for the service menu 103.
    Fig. 8 is a diagram showing a display example of the display for the service menu 103. In addition to menus such as "diagonal support", "monitoring" and "error history", the service menu display 103 also shows a down cursor icon 131, an up cursor icon 132, a backward icon 133 and a selection icon 134. in the lower part of the monitor. Among these, the cursor icon 131 and the cursor 132 indicate icons corresponding to a selector for moving a scroll bar 135 up and down scrolling service menus. These icons are arranged above the function keys F3 to F6 (see Fig. 5) to guide input buttons which in fact require a manipulative input. The case shown in Fig. 8 indicates a case where “monitoring” is selected from the service menu items shown in italics. Therefore, when the function key F6 is pressed in the case shown in Fig. 8, "monitoring" must be selected.
    If "monitoring" is selected in the monitor for the service menu 103, the controller 203 causes the display unit 202 to display a monitor corresponding to "monitor". The screen displayed by the display unit 202 varies depending on whether a monitoring object 11 is registered in the memory 206. To be more specific, if a monitoring object is not registered in the memory 206, the controller causes the display unit 202 to display a monitoring object selection screen 104 for requesting a monitoring selection object . On the other hand, if a monitoring object is registered in the memory 206, the controller causes the display unit 202 to display an inquiry screen 206 which makes a request as to whether the registered surveillance object should be displayed.
    Fig. 9 is a diagram showing a display example of the monitoring object selection screen 104. In the monitoring object selection screen 104 shown in the figure, objects to be monitored are selected from a number of objects (eg 200 objects) that can be monitored in the construction machine. Therefore, the monitor for monitor object selection 104 shows on its upper part a number fl of l04a to l04c which can change and display the monitor corresponding to each component such as the motor and the hydraulic pump mounted on the construction machine, and shows the central part of the monitor monitor object having to do with the selected fl icon. To be more specific, an fl ik l04a displayed as “ENG”, an fl ik 104b displayed as “PUMP” and an fl ik l04c displayed as “AIRCON”. Engine-related monitoring objects (such as engine rotation speed) are displayed when tab 104a is opened, hydraulic pump-related monitoring objects (such as pump injection pressure) are displayed when tab 104b is opened, and air-conditioning monitoring objects (such as cab temperature) and the air temperature outside) is displayed when fl iken l04c is opened. In the case shown in Fig. 9, the signal l04a is selected and monitoring objects related to the motor are displayed together with their identification number. An unselected monitoring object is displayed in blue, for example. The monitoring objects shown in Fig. 9 include "selected model name (identification number O020l)" which indicates the name of a selected model, "engine rotation speed (identification number 01002)" which indicates the engine rotation speed, "engine water temperature (identification number engine number 04107) cooling water, "battery voltage (identification number 03203)" indicating engine battery voltage, "common rail pressure (identification number 36400)" to indicate the common rail pressure of the fuel injector, "atmospheric pressure (identification number 37400)" to indicate the atmospheric pressure, (identification number 36500) ”to indicate the charge pressure corresponding to the air pressure produced by the turbocharger. Monitoring means other than those mentioned above can be displayed here by scrolling down the screen. 12 In the left-hand part of each monitoring object, a checkbox indicates “Ch” if the selected object is displayed. Under the monitoring object there is also a display area for identification number 141 to display the identification number of a selected monitoring object. In the case shown in Fig. 9, the check box "Ch" on the left-hand part of this monitoring object is checked, since only "00201 selected model name" is selected, whereby the monitored object that is selected is shown in red and only the identification number "00201" is displayed in the display area. for the identification number 141.
    Below the monitor object selection screen 104, there is a left shift icon 142 and a right shift icon 143 for selecting a tab, a down cursor icon 144, an up cursor icon 145, a backward icon 146 and a selection icon 147 arranged in this order from the left. These icons are respectively arranged above the function keys F1 to P6 to guide buttons which in fact require a manipulative input. In the monitor object selection screen 104, on the left side of the selection menu, there is also a scroll bar 148 which can be scrolled up or down by means of the function keys F3 and F4 corresponding to the down cursor icon 144 and the up cursor icon 145.
    There are two input methods for selecting a monitoring object. As a first input method, there is a method which: aims at a intended monitoring object by changing the scroll bar 148 while pressing the function keys F3 and F4 corresponding to the down cursor icon 144 and the up cursor icon 145; and then press the function key F6, which corresponds to the selection icon 147, to select. In this first method, the intended monitoring object is displayed in, for example, yellow. When the function key F 6 is pressed, the controller 203 changes the display color from yellow to red for the selected monitoring object and displays a check mark in the check box Ch of the monitoring object. In the monitoring object selection screen 104, after a monitoring object has been selected, it is possible to select a number of monitoring objects by repeating the same process. In the case of terminating the registration of a monitoring object, you can double-click the function key F6 or press it for a predetermined time or longer. The controller 203 which has detected a signal corresponding to this termination function causes the display unit 202 to display a monitor for monitoring design 105 which displays a result of the selected monitoring objects. 13 As a second input method for selecting a monitoring object, there is a method of directly entering the identification number of the monitoring object. In a case where the monitor object selection screen 104 is displayed, a number is entered when a selector having a number in its lower right part is pressed among the selectors of the display unit 201 instead of the function keys F1 to F6. For example, the number "1" is described in the lower right part of the automatic deceleration button 211, and when the automatic deceleration button is pressed, a state of the car screen for monitoring object selection 104 is displayed, whereby a signal corresponding to the number “1” is input.
    An identification number is entered in this way, and when the function key F6 is pressed, the controller 203 processes a monitoring object corresponding to the entered identification number as a selected state. By entering another identification number after the function key F6 has been pressed, it is in this case possible to select another monitoring object again. In the case when the monitoring object selection is completed, the function key P6 is pressed twice in succession. In this way, the controller causes the display unit 202 to display the monitor execution monitor 105.
    Fig. 10 is a diagram showing a display example of the monitoring design display 105. The monitoring design display 105 shown in the figure numerically shows the detected values of "selected model name", "motor rotation speed", "motor water temperature", "battery voltage", "common rail pressure ”and“ atmospheric pressure ”on each object line. The objects displayed on the monitor execution screen 105 indicate objects selected by the supervisor of the monitor object selection screen 104 in FIG. 9 to perform the monitoring. The monitoring object displayed on the monitor execution monitor 105 in Fig. 10 is therefore only an example. The specific, detected result for each monitoring object is updated sequentially.
    During the monitoring result, the monitor execution monitor 105 displays a motor water temperature gauge 155, an oil temperature gauge 156 and a fuel level gauge 157 in a simple manner. Below the engine water temperature gauge 155 or the like, a memory icon 151, a hold icon 152 and a backward icon 153 are further shown.
    "Displayed in a simple way" here means that the state quantity levels of the engine's cooling water temperature, the operating oil temperature and the remaining amount of fuel in a fuel tank are shown by bars and the type for each state quantity is shown with graphics (or patterns). Instead of displaying with bars, each state variable described above 14 can also be displayed with absolute values (such as degrees Celsius and liters) and in the case of the remaining fuel quantity, it can be displayed numerically with percent. By displaying each state variable with graphics, the service personnel and the like can thus confirm that there are no abnormalities (such as overheating due to excessive temperature of the engine cooling water temperature) in the state of the construction machine even when the monitor for the monitor design 105 is displayed.
    The upper right part of the monitor execution monitor 105 also shows the operating status icon IM and the driving speed level icon IS. The memory icon 151 is arranged at a position corresponding to the function key F1 and indicates an icon having a function for inputting a signal which instructs the memory 206 to register a displayed monitoring object. The hold icon 152 is also arranged at a position corresponding to the function key P4 and indicates an icon having a function of fixing and displaying an image displayed by the display unit 202 and registering the fixed data image as a snapshot in the memory 206. By arranging such a hold icon 152 it is possible to memorize the immediate numerical value of a changed image as a snapshot so that it is possible to achieve a better visibility for the manager when performing troubleshooting or examination and easy and reliable registration of numerical values in an examination table or the like. The rear icon 153 is arranged in a position corresponding to that of the function key P5.
    After the display becomes a hold state by pressing the function key P4 corresponding to the hold icon 152, when the display unit 202 shows the screen for the monitoring embodiment 202, if the function key P4 is pressed again, the controller 203 cancels the hold state. A hold cancel icon (corresponding to that of eg function key P3) can be displayed here after the monitor takes hold. In this case, the controller 203 cancels the hold state when the function key P3 is pressed.
    By arranging such a holding function when, for example, the manager checks the battery voltage, it is possible to read the voltage value displayed in the holding state instead of the voltage value which changes immediately, so that the manager can reliably register the voltage value in an examination table.
    Pig. 11 is a diagram showing a display example of the monitor execution monitor after pressing the function key P1, while the display unit 202 shows the monitor execution monitor 105 and then registers the displayed monitoring objects in memory 206, which is an enlarged view of the monitor execution monitor 105 "in Pig. The monitor for the monitoring embodiment 105 "shown in Fig. 11 shows a delete icon 154 on the right side of the memory icon 151 in addition to the displayed contents of the monitor for the monitor embodiment 105. The delete icon 154 is arranged above the function key F2 and indicates a switch having a function which deletes the monitoring object registered in the memory 206. Therefore, when the function key F 2 is pressed, the controller 203 deletes the registered monitoring object from the memory 206. After the registered monitoring object is deleted from the memory 206, the controller causes the display unit 202 to display the monitor execution 105 again. When the function key F1 corresponding to the memory icon 151 is displayed here, the controller 203 overwrites and stores a monitoring object to be registered in the memory 206. At the time, the display unit 202 continues to display the monitor execution monitor 105 ”.
    Fig. 12 is a diagram showing a display example of an inquiry screen, which is a screen transition, when a monitoring object is registered in the memory 206, in a case where "monitoring" is selected in the service menu screen 103. On the service menu screen 103, the request screen 106 shows , displayed in the clock, a message "Are the registered monitoring objects displayed ", the messages "No" and "Yes" and a backward icon 161 and a selection icon 162 corresponding to "No" and "Yes". If the function key F5 corresponding to "No" (ie the back icon 161) in the state shown in Fig. 12 is pressed, the controller 203 causes the display unit 202 to display the screen for monitoring object 104. On the other hand, the function key F6 corresponding to "Yes" (ie the selection icon 162) in the state shown in Fig. 12 is pressed, the controller 203 causes the display unit 202 to display the monitor for the monitoring design 105 ”.
    Fig. 13 is a schematic fate diagram schematically showing control examples of screen transitions shown above in Fig. 7 (Fig. 8 to Fig. 12). First, by activating the control key 41 (step S100), the standard display 101 is displayed on the display unit 202 (step S110). Then, if service personnel perform a predetermined procedure such as entering a password (step S120: Yes), the display of the display unit 202 transitions from a standard display 101 to a display for the service menu 103 (step S130). If there is no predetermined procedure (step S120: No), the default display 101 is displayed as it is. Then, if a designated menu is selected on the screen of the service menu 103 (step S140: Yes), it is determined whether there is a registered monitoring object (step S150). If there is a registered monitor object (step 16 S150: Yes), the display unit 202 will display the request screen 106 (step S160) to select whether the registered monitor object is displayed (step S165).
    If there is no registered monitor object (step S150: No) or if it is selected that registered monitor objects are not displayed (step S165: No), the display of the display unit 202 is transferred to the monitor object selection screen 104 (step S170). Then a designated monitoring object is selected (step S180). If a designated monitor object is selected (step S180: Yes), the selected monitor object is registered in a memory according to a procedure of a "CROSS" pushbutton corresponding to the function key F6 according to a procedure of a "MEMORY" pushbutton corresponding to the function key F 1 (step S190). Then, for example, a found value of the selected monitoring object is displayed on the screen for the monitoring embodiment 105 as the current found content (step S200). If it is selected that the registered monitoring object is displayed (step S165: Yes), it passes directly to the monitor for the monitoring execution 105 ", not via steps S170 to S190 to display, for example, a value found of the selected monitoring object as the current encountered content (step S200). If the selection is made to display the registered monitoring object (step S165: Yes), it is transferred directly to the monitor for the monitoring execution 105 ", not via step S170 to S190 to display, for example, a value found in the selected monitoring object as the current found content (step S200).
    After that, the process is repeated in steps S170 to S200 (step S210: No) until the control key 41 is switched off and, when the control key 41 is switched off (step S210: Yes), it is determined whether a predetermined time has elapsed after the key shut-off state (step S220). For example, it is assumed that the predetermined time in this case indicates a period of time during which the service personnel perform a procedure. If the predetermined time has not expired (step S220: No), it is determined whether the control key 41 has been switched on (step S230).
    If the control key 41 is switched on again during the predetermined time (step S220: No, step S230), for example, the value found (i.e. the current found content) of the registered monitoring object is displayed on the monitor execution monitor 15 or 105 ”. When the predetermined time for fl has expired after the key shut-off condition (step S220: Yes), the procedure is completed.
    In Embodiment 1 of the present invention described above, in a case where the monitoring object is selected in the display for the service menu 103, if a monitoring object is registered in the memory 206, it is transmitted to the monitoring embodiment screen 105 "via the interrogation screen 106 so that it is not necessary to select a monitoring object in each case. Therefore, it is possible to effectively perform monitoring when the manager performs maintenance.
    (Embodiment 2) Configurations of a monitoring device and a control system including the monitoring device according to this Embodiment 2 are similar to the configurations of the monitoring device 21 and the control system explained above in Embodiment 1. Below, each component of the monitoring device and control system will be explained by the same reference numerals. Fig. 5.
    Fig. 14 is a diagram showing a screen transition in the display unit 202 of the monitoring device 21 in a case where monitoring with the monitoring device 21 is performed. When the supervisor performs monitoring, the "monitoring" menu is first selected from the screen for the service menu 103.
    When "monitoring" is selected in the display of the service menu 103, the controller 203 causes the display unit 202 to display a display corresponding to "monitoring". The screen displayed by the display unit 202 varies depending on whether a monitoring object is registered in the memory 206.
    If no monitoring object is registered in the memory 206, the controller causes the display unit 202 to display the monitoring object selection screen 104 shown in Fig. 9. By double-clicking or pressing the function key F6 corresponding to the selection icon 147 (see Fig. 9) for a predetermined time or longer in a state where the monitoring object selection screen 104 is displayed, the controller 203 causes the display unit 202 to display the monitoring execution screen 105 shown in Fig. 10.
    Below, a case will be described when there is a monitoring object registered in the memory 206. In this case, the controller 203 causes the display unit 202 to display a monitor for monitor object selection 107 which differs from the above monitor for monitor object selection 104. Figs. 15 is a diagram showing a display example of a monitor object selection screen 107. The monitor object selection screen 107 shown in Fig. 15 shows the monitor object selection screen 107, a left shift icon 172, a right shift icon 173, a down arrow icon 174, a cursor icon 174, a selection icon 177 and an icon 107d displayed as “MEMORY”, in addition to a number of icons 107a to 107c corresponding to the number of tabs 104a to 104c of the monitoring object selection screen 104 in Figs. 9, 18 where the icon 107d is open. Tab l07d shows monitoring objects registered in memory 206 (ie “selected model name, engine rotation speed”, “engine water temperature”, “battery voltage”, “common rail pressure” and “atmospheric pressure”).
    In the display state in Fig. 15, if the function key F6 corresponding to the selection icon 177 is pressed, the controller 203 causes the display unit 202 to display the monitor for the monitor design 105 "shown in Fig. 11. The screen transition between the monitor for the monitor embodiment 105" and the monitor for the monitor embodiment 105 is same as in Embodiment 1 described above.
    From the display state in Fig. 14, it is possible here to switch to monitors other than the monitor for the monitoring design 105 "shown in Fig. 13. To be more specific, when a tab is shifted by using the function keys F1 and F2 corresponding to the left shift icon 172 and the right shift icon 173, the display unit 202 shows monitoring objects based on the selected fl ik. Fig. 16 is a diagram showing a display example of monitoring selection menus in a case where fl icon l07a displayed as “ENG” is selected after the monitoring object selection screen 107 state shown in Fig. 15 (i.e., the state where fl icon l07d has been selected). Fig. 16 shows a state where the monitoring objects registered in the memory 206 through the monitoring object selection screen 107 shown in Figs. 15, all are registered. Although Fig. 15 shows a state where only the monitoring objects included in fl iken l07a are registered in memory 206, this is only an example and a case is possible where the monitoring objects included in fl iken l07b (PUMP) or fl iken l07c (AIRCON ) are registered in memory 206.
    In a state where the display unit 202 shows the monitor for monitoring object selection 107 shown in Fig. 16, when the function key F 6 is pressed after an unregistered monitoring object becomes a selected state (shown in yellow) by changing the scroll bar 178 by using e.g. F3 and F4, the controller 203 processes the selected monitoring object as in a registered state, changes the display color of the screen from yellow to red and displays a check mark in the check box Ch of the monitoring object. At the same time as when a registered monitoring object obtains a selected state ("00201 selected model name" in Fig. 16) by changing scroll bar 178 as above and further pressing the function key F6, the controller processes the selected monitoring object as an unregistered state, 19 changes the display color in the screen to blue and deletes a check mark from the check box Ch for the monitoring object.
    Thus, after the controller 203 has added or deleted a monitoring object to be registered in the memory 206, when the function key F6 is double-clicked or pressed for a predetermined time or more, the controller causes the display unit to display the monitor execution monitor 105. In a case where a monitoring object added or deleted, it is possible here to use an entry method (ie the second entry method described above) for direct entry of an identification number.
    According to Embodiment 2 of the present invention described above, in a case where monitoring has been selected in the display of the service menu 103, when a monitoring object is registered in the memory 206, the display unit 202 shows the registered monitoring object in each vid ik when displaying the monitoring object selection screen 107, that the supervisor can confirm which monitoring object is registered before performing the monitoring. It is also, in Embodiment 2, easily possible to add or delete a monitoring object in the memory 206, so that it is possible to perform more efficient monitoring.
    (Embodiment 3) An object of Embodiment 3 of the present invention is to effectively perform monitoring in a case where a key activation or key activation procedure is performed while monitoring the engine coolant temperature, operating oil temperature and the remaining fuel in the fuel tank for the manager's troubleshooting.
    Fig. 17 is a diagram showing an overview of characteristic procedures of monitoring procedures performed by a monitoring device according to Embodiment 3 of the present invention. An embodiment of a control system that includes the monitoring device according to Embodiment 3 is here the same as the embodiment of the control system in Embodiment 1 as described above. In Embodiment 3, when a key activation signal is input by the control key 41 in a state where the monitor execution monitor is displayed, the controller 203 turns off the display unit 202 light and registers the monitoring object displayed by the monitor execution monitor 105a in the memory 206. When a control key is entered 41 and the signal detection unit 205 detects the key activation signal, the controller 203 then calls for information from the monitor for the monitoring embodiment 105b in which the monitoring objects are registered immediately after the key activation state has been selected from the memory 206 and causes the display unit 202 to display them. Here it is not necessary to say that the results found are generally different between the monitors for the monitoring design l05a and l05b.
    According to Embodiment 3 described above, when a key activation signal is input by the control key 41, since the controller 203 causes the display unit 20 to display a screen before a key activation state (ie, monitoring objects registered in the memory 206), in the case of checking a mechanical behavior at key activation , it is not necessary to transfer to the service menu monitor 103 via the default monitor in the key activation mode and select the “monitoring” menu. Therefore, it is possible to perform monitoring effectively.
    Fig. 18 is a diagram showing an overview of characteristic methods of the monitoring device according to a modified example of Embodiment 3. The monitoring device according to this modified example has a function of changing a display shown by the display unit 202, immediately after a key activation signal is found, according to the time from the time that the signal detecting unit 205 encounters a key activation signal until it encounters a key activation signal.
    In this modified example, the controller 203 turns off the light of the display unit 202 when a signal detecting unit 205 encounters a key deactivation signal in a state where the display unit 202 displays the monitor for the monitoring embodiment 105a. When the signal detection unit 205 encounters a key activation signal within a predetermined time after the key activation signal is found, the controller 203 then causes the display unit 202 to display the monitor execution monitor 105b. Unlike when the signal detecting unit 205 finds the key activation signal after the predetermined time has elapsed after the finding of the key deactivation signal, the controller 203 causes the display unit 202 to display the standard display 101 in the same manner as in the case of normal activation. The time elapsed from the detection of the key activation signal by the signal detecting unit 205 is measured by the IC clock 204. With respect to the predetermined time which is a threshold used when the controller 203 determines which of the standard monitor 101 and the monitor execution monitor 105a is displayed on the display unit 202. it is sufficiently determined that with regard to the necessary time from when the manager sets a key activation state until when the manager sets a key activation state under supervision and when the key activation state is set with the predetermined time, it can be determined that there is a high probability that the general user the key activation state.
    According to the modified example of Embodiment 3, for example in a case where the supervisor terminates the maintenance without exiting the service menu, the standard monitor 101 will be displayed when a general user subsequently activates the construction machine, so that it is possible to prevent the monitor performance monitor from being displayed when general user starts a procedure. Therefore, the general user can perform a normal procedure without feeling insecure. Although the preferred embodiment for implementing the present invention has been described above, the present invention is not limited to Embodiments 1 to 3 described above. For example, the display unit according to an aspect of the present invention may be mounted on the construction machine such as on a dozer and a wheel loader. The present invention thus includes various embodiments, more than those above.
    Industrial Applicability As described above, a work vehicle monitoring device according to one aspect of the present invention is useful for a work vehicle such as a construction machine and is particularly adapted to a case where maintenance on a work vehicle is performed.
