    US2008 / O036595A1 discloses a portable security system for remotely monitoring a location.
    The system is primarily intended to monitor a place against intruders, such as thieves. The system can also contain a smoke detector and can then be used to detect fire on site.
    The system contains a portable monitoring unit in the form of a bag comprising a housing and a server unit arranged to communicate with the monitoring unit and to send alarms to the server unit. Inside the case of the bag there are one or more sensors for detecting movement, heat, smoke or electric fields, an alarm equipment triggered by the sensors, a communication unit arranged to communicate wirelessly with the server unit and a battery for supplying power to the monitoring unit. On the front of the housing there is a user interface designed to display alarms, enable settings of the sensor and acknowledgment of alarms. To monitor a location, the bag is placed in a suitable place, and if an intruder is detected, an alarm is sent to the server, which in turn forwards the alarm to an alarm center or to a portable key unit that the owner can carry with them. Such a monitoring unit is not always suitable for use in hot work that is often performed in difficult environments where it is difficult to access to monitor certain parts of the workplace and it is hot and smoky, which can damage the bag and its contents. Sometimes the place to be monitored is large, and a bag is not enough to monitor the whole place. In such cases, it becomes expensive to use several bags.
    GB2471784 discloses a monitoring system containing a plurality of transportable towers located at the site to be monitored and a monitoring station located at another location remote from the monitored site. Each of the towers contains a pull-out mast and a surveillance camera arranged at the top of the mast. There is also a motion detector on the mast which sends out an alarm that a motion has been detected. On the ground at a distance from the mast, there is also a safety sensor arranged which can, for example, detect smoke, gas, fire or water. Each of the towers contains a portable base station that can communicate with the monitoring station and send an alarm to it if a security incident is detected. The system is configured from the monitoring station and does not provide the ability to make settings and acknowledge alarms on site. OBJECTS AND SUMMARY OF THE INVENTION The object of the present invention is to provide a portable monitoring unit which makes it possible to monitor in a simple and safe manner a workplace where hot work is performed or has been performed.
    According to one aspect of the invention, this object is achieved with a monitoring unit according to claim 1. According to the invention, the detector finding stage comprises a Lipplzadairiingstazart battery and the bag is tattooed so that the battery can be charged automatically when the detector unit is stored in said space bag. For example, the bag contains a contact device arranged for connection to an external power source, and said means for storing the detector unit are designed so as to accommodate the storage device in the citrine system; in the bag that the battery is charged; up automatically .where the battery in the clector connector is in electrical contact need said contact device is connected to the power source. In this way, the detector units can easily be charged when stored in the bag. No separate charging device is required to charge the detector units. The detector units are protected in the bag while they are being charged. The monitoring unit is in the form of a bag comprising an openable housing, an electronics unit, at least one detachable detector unit, and space for storing the detector unit, the detector unit comprising a sensor arranged to detect a security incident, such as fire hazard and a communication unit arranged to communicate wirelessly. external server unit and send alarms to the server unit if a security incident has been detected, and the electronics unit includes a user interface designed to make settings of the sensor, display alarms and enable acknowledgment of alarms, and a communication unit arranged to wirelessly communicate with the external server unit and receive alarms from the server device.
    According to the invention, the bag is provided with one or more detachable detector units which communicate directly with an external server unit and have their own power supply. The bag is designed for storage of the detector units when not in use and during transport. Thanks to the fact that the detector unit is detachable from the bag, it is possible to place the sensor close to the place to be monitored, where there is a risk of fires, and at the same time place the bag, which contains the electronics unit and user interface, some distance from the place to be monitored. . The bag can, for example, be placed in an adjoining room. In this way, dangerous and / or cordoned off production spaces can be monitored and alarms can be acknowledged without any person having to stay on site. If the bag contains several detector units, it is possible to place these in different places and thus monitor a larger area.
    The electronics unit and the detector units communicate with each other via the server unit, which gives a great deal of flexibility in the system. This means that no extra equipment is needed for communication between them. The range between the electronics unit and the detector units thus becomes unlimited, which means that there is no limitation on the distance between the electronics unit and the detector units. It is also possible to have different numbers of detector units in a group and to link two or more groups of detector units to each other via the server. 10 15 20 25 30 35 The bag is easy to carry to different workplaces and contains a user interface that can be used to make settings of the sensor and acknowledge alarms. It is important that the alarm is acknowledged by a person who is on site and who can decide what to do to take care of the fire.
    The invention means that the time for follow-up can be extended considerably and contributes to an increased fire safety during hot work. The invention provides opportunities to facilitate and streamline the current fire protection, which in the long run saves large costs in unnecessary downtime and other cost-intensive operational disruptions.
    According to an embodiment of the invention, the housing is arranged to enclose the electronics unit and the space for storing the detector unit when the bag is closed, and the user interface is positioned so that it is only accessible when the bag is open. The user interface may, for example, comprise a push button for acknowledging alarms, and the button is placed inside the bag so that it is only accessible when the bag is open. In this way, the electronics unit and the user interface are protected from smoke, dust and other dirt that often occurs in the type of workplace where hot work is performed, when the bag is closed.
    According to an embodiment of the invention, the bag contains at least one detachable and collapsible stand for holding up the detector unit, and a space for storing the stand.
    The bag is designed to store one or more racks to hold up the detector unit.
    The racks can be stored in the bag when the racks are not in use and during transport. Thanks to the stand, the detector unit can be positioned so that it monitors the location in a better way.
    According to an embodiment of the invention, the bag contains two halves and a partition arranged between the two halves, one half containing said electronics unit and said space for storing the detector unit, and means designed to protect the detector unit and the electronics unit from shocks, and the other half contains said space for storing the stand. One half of the bag is designed to protect sensitive equipment such as the detector unit and electronics unit, and the other half is designed to store more robust equipment such as the racks. A partition separates the two halves and protects the sensitive side. This embodiment makes it possible to store both the racks, the detector units and the electronics unit in the same bag. éeteletereriä-etee-iäëvarea-á »- mentioned - space - in - the box -Example - inneåæållee fl-- väskarfe-en» iee-wtakt-aane-rdeairag - azma-F-: alrwaä - šéà fi -ara-sl-eata-irag - tli-l - een - ytëæe - sftrörnkêàllaay- »eseh - raäeneæešea-etfwmm-e - fëär fi .g -«.,. - - .., .. - ° 10 15 20 25 30 å; ait-teri-eat-isa-eldeæfsupp »-zau1asmaaiá fl sækt-nêâr-nåârrsneàea-kemtalíltaairaereäfrsiræg-åär-araeslutean-till-strërnkäiliea-raT-På. ........... i .........,. «. _ .. ~, .. u.

    Figure 1 shows a perspective view of a portable monitoring unit in the form of a bag according to a preferred embodiment of the invention; Figure 2 shows a perspective view of the portable monitoring unit of Fig. 1 where the bag is open and shows one half with components of the monitoring unit and a partition; Figure 3 shows a perspective view of the portable monitoring unit of Figures 1 and 2 where the bag is open and shows the other half with the frame folded and the partition wall; Figure 4 shows a perspective view of a detachable detector unit of the monitoring unit; Figure 5 shows a circuit diagram of the detachable detector unit of Figure 4; Figure 6 shows a schematic view of a monitoring system according to an embodiment of the invention containing a server communicating with a number of components of the portable monitoring unit; and Figure 7 shows a schematic view of the portable monitoring unit during operation and a person communicating with the monitoring unit by means of a hand-held communication unit.
    Detailed Description of Preferred Embodiments of the Invention Fig. 1 shows a portable monitoring unit 1 in the form of a bag containing a number of components. The bag 1 comprises a housing 2 and a handle 3 for easy handling and movement, as well as a contact device 4 which is arranged for connection to an external power source (not shown). The contact device can be of the male or female type. The cover is made of a hard material to protect the contents of the bag. By connecting said contact device 4 to the power source, for example by the contact device 4 being designed as a roll-out socket for connection to a power outlet, components inside the bag 1 can be charged to enable operation where the monitoring unit 1 does not need to be connected to a power source.
    Alternatively, of course, the monitoring unit 1 can be connected to the power source even during operation, although this generally limits the location of the bag 1 to places in the vicinity of power outlets.
    Furthermore, the bag 1 preferably comprises at least one indicator lamp 5 for indicating alarms and / or charging of components inside the bag 1. The bag can also be equipped with acoustic and / or optical alarm devices. The optical alarm can be one of the indicator lights or a separate device. The bag shown in the figure is provided with an acoustic alarm device 6 in the form of a siren which begins to sound when an alarm has been detected.
    Fig. 2 shows the portable monitoring unit 1 with the bag opened so that a number of components of the monitoring unit 1, arranged in one half 7 of the bag, are visible. At least one detachable detector unit 10 is arranged in a space 11 intended for this purpose in a means 17 designed to protect the components from shocks. Preferably, the bag contains a plurality of detector units 10 arranged in the space 11. The means 17 is preferably formed in a soft material, such as injection molded foam plastic. Each of the detector units 10 contains a rechargeable battery 27 (see Fig. 5). In the vicinity of this space 11 there is also a charger 19 arranged to charge the batteries in the detector units. Furthermore, one half 7 also contains an electronics unit 13 arranged to control the operation of the portable monitoring unit 1, and which contains a user interface 14 in the form of a screen 14A, and a keypad 14B for enabling communication with the monitoring unit 1 and an external server. Preferably, the screen and keypad can be replaced with a touch screen / touch screen. Electronics unit 13 is preferably a computer. In addition, an acknowledgment button 15 is provided connected to the electronics unit to acknowledge an alarm triggered by the portable monitoring unit 1, as well as a rechargeable battery 20 to the electronics unit 13.
    All these components are embedded in the means 17 to protect against shocks, so that the bag 1 can be subjected to a relatively harsh treatment without the portable monitoring unit 1 being damaged in such a way that the operation is disturbed. The acknowledgment button can also be used to confirm local presence at the site. It is ok to make improvements to the monitoring via external mains connection, but no deteriorations may be made, as these must always be confirmed by the acknowledgment button in the bag.
    The user interface 14 is designed to be able to make settings of the sensor 24 of the detector unit 10, display alarms and enable acknowledgment of alarms through the acknowledgment button 15.
    The bag 1 and all connections to it should have at least an IP54 rating and be shockproof and have a low center of gravity to stand firmly on a flat surface. Thanks to such robustness, components inside the bag 1 can be protected, which increases operational reliability and service life of the components included.
    The charger 19 of the detector unit 10 and the rechargeable battery 20 are in electrical contact with the contact device 4 so that they can thereby be connected to a power source for charging. The charger 19 contains a transformer which converts mains voltage to a suitable voltage for charging the batteries. The charger controls the charging of all the units' batteries 20,27 when it is connected via the external connector 4 on the bag. Inside the bag 1 there is also cabling (not shown) which is arranged to establish electrical contact between the various components as described herein.
    It is advantageous if both the detector unit 10 and the battery 20 can be charged simultaneously. In some applications it may also be advantageous to arrange the electronics unit 13 in electrical contact with said contact device 4 so that it can be operated by means of an external power source without the battery 20 being used. The external power source can be, for example, a wall socket in a building or a cigarette socket in a car, but other power sources can of course also be used if it is suitable for a given application. Thus, the portable monitoring unit 1 can be adapted to be able to be charged both with voltage sources in the range 9-24V, as is commonly found in, for example, a cigarette socket in a car, and voltage sources which provide 230V as provided by a wall socket in a building. Other voltage levels can of course also be used if appropriate in a given application. It is advantageous to be able to use the voltage source that happens to be at hand at the place where the invention is to be used to detect a security incident.
    Adjacent to the electronics unit 13 is arranged a first communication unit 16 (not shown) which enables wireless communication between the electronics unit 13 and an external server unit 30 which in turn communicates with both the detector unit 10 and a mobile handheld communication unit 31 and any other units.
    In this preferred embodiment, however, the electronics unit 13 is arranged to use the rechargeable battery 20 as a power source so that the portable monitoring unit 1 can be used independently of access to an external power source. Although the invention can be used in conjunction with only one detector unit 10, in many applications it is advantageous to use a plurality of detector units 10A, 10B, 10C, 10D spaced apart so that a security event can be detected over a larger area.
    The electronics unit 13 can advantageously be an industrial PC or tablet based on Windows, iOS, Andrioid or Linux, and should in that case be fanless and power-efficient, with a built-in Watch dog which is arranged to restart the computer if the system hangs. Parameters in the form of sensor settings and an emergency number to contact in the event of a security incident can advantageously be saved in a configuration file that is used if the electronics unit 13 is restarted. The first communication unit 16 which is connected to the electronics unit 13 advantageously comprises a GSM / GPRS / 3G modem with connection to an external antenna which enables communication even in places where the coverage of the mobile network is weak.
    In a particularly preferred embodiment, the portable monitoring unit 1 is provided with a GPS function so that one can determine the coordinates of the bag 1 and thereby facilitate an alarm to the fire brigade and at the same time make the unit 1 more theft-proof, since its position can then be determined even after been stolen.
    Fig. 3 shows the second half 8 of the bag 1, with space for storing at least one detachable stand 21 with a telescopic rod which can be mounted together with the detector unit 10 so that said detector unit 10 is kept at a suitable distance from the floor or ground where it is used. . Of course, other types of racks can also be used and it is conceivable that the bag 1 is arranged to contain one or more racks depending on the application and the number of detector units. Between one half 7 and the other half 8 of the bag 1 there is a partition 9 of a suitable material, preferably a plastic material, to separate the halves 7, 8 and further dampen any shocks against the bag 1.
    Fig. 4 shows one of the detachable detectors 10 comprising a sensor 24 arranged to detect a security event, for example a fire, in that the sensor 24 comprises a smoke detector, a heat detector, a camera, a motion detector or a thermal camera. The sensor 24 may comprise only one of these but advantageously more than one. The detector unit 10 further comprises a processor unit / CPU, a rechargeable battery 27, and a second communication unit arranged to communicate wirelessly with the external server.
    The detector unit has a housing 25 with a grid cover which encloses the sensor, the battery and the other units.
    Fig. 5 shows the internal measurement of a detector unit 10 in the form of a wiring diagram with a processor unit / CPU 28, the sensor 24, a memory unit 29, a rechargeable battery 27 for the sensor, and a second communication unit 26. The second communication unit 26 advantageously comprises a GSM / GPRS / 3G modem with connection to an internal antenna or external antenna that enables communication even in places where the mobile network coverage is weak.
    Said second communication unit 26 is arranged to communicate wirelessly with the external server 30, as explained in more detail below. The space 11 is designed so that the rechargeable battery 27 is automatically connected to the charger 19 when the detector unit 10 is placed in the space 11. In this way, automatic charging of the batteries in the detector units is enabled when they are stored in the bag. Alternatively, a wiring harness with connectors may be included with the bag, which can be manually inserted into each detector unit.
    Fig. 6 shows an example of a monitoring system according to the invention with an external server 30 which is arranged to communicate wirelessly with a number of detector units 10A, 10B, 10C, 10D with each first communication unit, two mobile handheld communication units 31A, 31B, for example in the form of mobile telephones, as well as two electronic units 13A, 13B, each with a first communication unit 16A, 16B.
    Fig. 7 shows the use of the portable monitoring unit 1 according to the preferred embodiment, where a user with a mobile handheld communication unit 31 communicates wirelessly with the external server, and a first detector unit 10A is mounted on a detachable and collapsible first telescopic stand 21A with a first telescopic rod 22A, and a second and third detector unit 10B, respectively. 1OC are mounted on a second telescopic stand 21B with a second telescopic pole 22B. Between the two racks there are obstacles in the form of blocks and thanks to the use of several detector units 10A, 10B, 10C, safety incidents can be detected over a larger area and on different sides of these obstacles. The use of a portable monitoring unit according to the invention will now be explained in more detail with reference to the figures.
    The portable monitoring unit is preferably used in a workplace where hot work has been performed and it is therefore considered that there is a risk of a safety incident in the form of a fire occurring some time after the work has been performed.
    First clean and, if necessary, water the workplace and its immediate area. When this has been completed, an assessment is first made of how many detector units10 are required to frame the risk area and where these should be placed. Then the desired number of detectors 10 are placed out, preferably mounted on stand 21 at a suitable height above the floor. After this, detectors 10 are also rigged up in adjacent spaces if these involve a risk situation (as in some cases it is difficult to fully guarantee tight penetrations so that a fire hearth cannot occur). Thus, when the detectors 10 are deployed and activated, they can communicate wirelessly via each other communication unit 26 with the server unit 30 which is connected to the first communication unit 16 of the electronics unit 13 in the bag 1.
    By using the user interface 14, i.e. the keypad 14B and the screen 14A can a user select the appropriate settings of the portable monitoring unit 1 so that the desired monitoring of the area is obtained. The screen is preferably a touch screen, in which case the keypad 14B can be omitted. The bag 1 is preferably connected to an external power source during operation, so that the risk of malfunctions due to discharged battery can be avoided. However, in order to ensure that the monitoring unit 1 can be used even in the event of a power failure, it is suitable that the rechargeable battery 20 can function as a backup.
    It is advantageous if the screen 14A has a display with a touch screen which works even when the user is wearing gloves and which is resistant to shocks and blows and is visible both in the dark and in full sunlight.
    After deployment of the detector units 10, the portable monitoring unit 1 is tested by a user to check that all sensors 24 to be used function normally and are in contact with the server 30. Thereafter, the user enters a telephone number using the keypad 14B and the test ring number 1 of the monitoring unit 1 for to check that it is correct. Advantageously, a number is selected which goes to a pre-appointed fire guard and when he confirms the call the monitoring unit 1 is started and activates monitoring of the area.
    The telephone number entered can alternatively indicate an alarm box that is included in the equipment and goes to a designated fire guard who is in the immediate area, for example guard personnel or other personnel who are in production within the unit. The after-guard is activated by a test call to the already appointed fire guard, who then receives information that the work has been completed and that the repairman is leaving the work area. Alternatively, the repairer can take care of the firefighting assignment himself when there are no qualified personnel available for this task.
    In a particularly preferred embodiment, the portable monitoring unit 1 can also be provided with a sprinkler system which is easily mounted in the same position as the detectors and which is arranged to communicate wirelessly with the monitoring unit 1. This is suitably activated via the detectors 24 to the mobile unit 31 which in turn opens. a radio-controlled valve that should be time-controlled. This is so that it will only put out the fire and thus avoid water damage.
    The alarm goes off so that a natural person comes and checks the work area. The valve opens again automatically if the detectors are affected.
    It is advantageous to be able to enter several different emergency numbers with different priorities, and it should also be possible to establish contact with an alarm center so that the fire brigade can be called to the scene if a fire occurs that cannot be quickly extinguished or obtained under control. To enable such communication, the electronics unit 13 and the first communication unit 16 are arranged to be able to communicate with a remote server via GPRS / SMS or 3G. Thanks to such a connection, the monitoring unit 1 can connect to TCP / IP networks and thereby remotely connect to a control center or directly connect to an alarm center, and also enable contact for service or help online.
    If a sensor 24 of a detector unit 10 then detects smoke, abnormal heat generation or any other factor indicating the occurrence of a fire, i.e. a security event, this is communicated in the form of a signal to the electronics unit 13 via the server unit 30, and the indicator lamp 5 of the bag 1 starts flashing red. If desired, the detector unit 10 can also alarm itself by having a unit for sound or light signal (sirens and / or mixer / lamp) connected to or integrated with the detector unit and can be activated when a safety event has been detected.
    The detector units 10 can thus be placed close to the place where the work is in progress or has taken place, where there is a risk that fires may occur, at the same time as the bag containing the sensitive electronics unit 13 can be placed some distance from that place.
    When the electronics unit 13 has received a signal indicating that a security event has occurred, an alarm also goes to the alarm number entered in the user interface 14, corresponding to a mobile handheld communication unit 31 such as a mobile telephone, and an operator is called to the location. He acknowledges the alarm by pressing the offset button 15, thereby indicating that the alarm has been received and that the location has been checked. The operator must therefore go to the bag and acknowledge the alarm. If the detector still detects something after a certain time, the alarm goes off again. It is advantageous that the set-off button 15 and the user interface 14 can only be used when the bag 1 is open and thus protected by the cover 2 when the bag 1 is closed. This significantly reduces the risk of damage even in dirty or hot environments where electronic components would otherwise be subject to significant wear.
    Power supply of the sensors 24 can take place by charging a rechargeable battery 27 to the sensor when the detector unit 10 is in the bag 1, but alternatively the ordinary primary battery can instead be used in the detector unit 10 and replaced if necessary. In order to operate the portable monitoring unit 1 as energy-efficiently as possible, the electronics unit 13 can be kept in a standby position and activated only when an alarm occurs, possibly also to send a status message at regular intervals indicating that the system is operating normally. As advantageous (NiMH) lithium ion batteries (Li-ion) are used, but also other battery types are of course possible. rechargeable batteries may be nickel-metal hybrid batteries or The present invention is not limited to the embodiments shown but may be varied and modified within the scope of the appended claims. For example, the number of detector units and racks may vary from one up to ten, or even more depending on the size of the bag and the need for detector units. The bag can be designed in many different ways but still have the same basic functions. 10 15 20 25 30 35 ÉPWFWWPP-'NF IJ IJ | - f ”IJ UJ IJ J> IJ U1 IJ CD IJ | | - 9 ° IJ KD k) O k) IJ 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 13 Reference list Portable monitoring unit in the form of a bag Höue, Handle Contact device arranged for connection to an external power source indicator lights Acoustic alarm device One half The other half Partition arranged between the two halves.
