    专利说明:

    Measures have been taken to avoid false alarms in some monitoring systems by detecting false alarms that reduce the number of alarm trigger signals sent to the operator.
    Thus, sometimes one and the same event, which may be false or true, triggers the surveillance camera or cameras more than once, which gives a number of alarms for one and the same event. An example could be an object in the form of a plastic bag that is transported by a blowing wind that gives a number of false alarm signals to the camera or cameras.
    Similar false alarm trigger signals can occur, for example, when it is snowing, when snow ings trigger the same camera fl times, which gives rise to false alarm signals that exhaust the operator as he / she must evaluate each alarm signal.
    Despite the various measures to avoid false alarms, there is sometimes a stressful situation for the operator who has to evaluate an excessive number of alarms for his / her capacity. This is of course a disadvantage.
    Thus, there is a need to address at least some of the disadvantages set forth above.
    Brief Description An object is to provide an alarm handling device, a monitoring system and a method for handling alarms, which solve at least some of the above-mentioned disadvantages.
    The above objects are achieved by means of an alarm handling device, a monitoring system and a method for alarm handling according to the independent claims.
    A first object provides a device for handling alarms in an alarm management system. The device comprises an alarm evaluation and control unit with a first, second and third interface. The first interface is designed to communicate with and receive an alarm signal from a monitoring detector device, the second interface is arranged to communicate with an alarm signal control device arranged to control a state of the alarm signal having a first or a second state.
    The alarm input control device is further arranged to provide an alarm to an operator thereof if the input signal is in the first state, by setting the alarm signal to the second state, whereby the operator handles the alarm signal and a resulting reset signal is arranged to be fed back to the alarm system control unit. to reset the alarm signal to the first state.
    A second embodiment provides a monitoring system, which comprises at least one monitoring detector device, at least one monitoring display presenting monitoring information to an operator and a device for handling alarms in a monitoring system. The device comprises an alarm evaluation and control unit with a first, second and third interface. The first interface is designed to receive an alarm signal from said at least one monitoring detector device. The second interface is designed to communicate with an alarm signal control device arranged to control a state of the alarm signal with a first or a second state.
    The alarm input control device is further arranged to provide an alarm to an operator thereof if the input signal is in the first state, by setting the alarm signal to the second state, the operator handling the alarm signal and a resulting reset signal being arranged to be returned to the alarm system control unit to reset the alarm signal. first condition.
    A third embodiment provides a method for handling alarms in a monitoring system. The method comprises: - in an alarm control unit receiving an input signal from a monitoring detector device via a first interface, -communicating with an alarm input control unit via a second interface, -controlling a state of the alarm signal with at least a first or second state, -setting the alarm signal to the second state, - presenting an alarm to an operator thereof if the input signal is in the first state, the operator handling the alarm signal and a resulting reset signal being arranged to be fed back to the alarm system control unit to reset the alarm signal to the first state.
    An advantage of some embodiments described here is that they prevent a number of alarm trigger signals from being produced for an event. Only one alarm trigger signal will be produced for one and the same event for one and the same camera. 10 15 20 25 30 Problems relating to operators who have problems handling an excessive number of alarms for his / her capacity are thus avoided.
    Further advantages and features of the embodiments of the invention will become apparent upon reading the following detailed description taken in conjunction with the drawings.
    Brief Description of the Drawings Fig. 1 is a schematic block diagram of a monitoring system in which embodiments of the invention are implemented.
    Fig. 2 is a schematic block diagram of an alarm handling device according to an embodiment of the invention.
    Fig. 3 is a fate diagram showing an embodiment of a method for handling alarms.
    Detailed description The invention will now be described in more detail below with reference to the accompanying drawings, in which various exemplary embodiments are shown. These exemplary embodiments are given so that this description is detailed and complete and not as limiting.
    Fig. 1 shows an example of a monitoring system comprising a land management device in which embodiments of the invention can be implemented.
    As shown in Fig. 1, the monitoring system 10 comprises a number of monitoring detector devices 15, here four. The surveillance detector devices 15 may be in the form of surveillance cameras, such as CCD cameras covering a surveillance area 16. The surveillance system 10 further comprises an alarm handling device 12 (shown in a dashed line) for handling alarms.
    The alarm handling device 12 is connected to, or can communicate with, the monitoring detector devices 15 and a display unit 19, which may comprise a number of display subunits 19a, b, which for example correspond to the number of cameras 15. For example, a camera 19a may display a real-time image of the monitoring area 16. that another camera 15 can display a stored sequence of images 19b that have been stored due to an event. The event that triggered the camera or 15 or the cameras may, for example, be something unusual that occurred. An example of an event which gives a false alarm trigger signal, hereinafter referred to as "" alarm signal "" L is an object in the form of a plastic bag which is transported by a blowing wind which gives a number of false alarm trigger signals to the camera or cameras. . For example, if a person climbs over a fence surrounding the monitoring area 16, a true alarm signal will be produced. In some systems 10, “intelligent” detectors may be provided which can reduce the number of alarm trigger signals given by various measures. However, this will not be described in this context.
    Here, the term "alarm signal" includes any component or parameter that represents a particular "alarm".
    Here, the term "event" refers to anything that gives an alarm signal L. Typically, an event is something unusual that has happened.
    Referring now to FIG. 2, which shows a schematic block diagram of an alarm handling device according to an embodiment of the invention.
    The alarm handling device 12 comprises an evaluation and control unit 12a implemented, for example, in a computer server, such as a Video Management System Server (VMS server), in which computer programs such as scripts can be implemented by a person skilled in the art of computer programming. The alarm handling device 12 typically includes a first, second and third interface 14, 17, 18, although interfaces already present in the VMS server may also be used to the extent desired. For simplicity, only one interface 14, 17 and 18 is shown, although it is obvious that all cameras 15 communicate the first interface 14, etc.
    Typically, the evaluation and control unit 12a receives images produced by, or transmitted from, the monitoring detectors 15, typically the cameras, via the first interface 14, evaluates them, and finally sends them via the third interface 18 to the display unit 19 monitored by an operator (not shown). ). Typically there is also an alarm signal control device 12b, a database 12c for storing data and / or computer programs, typically for implementing alarm handling device 12. There is also an application unit l2d for handling alarms and events. The application unit 12d may contain and provide video control functions required, including such functions, which will not be described in more detail, as will be apparent to those skilled in the art of surveillance systems and programming.
    Reference is now also made to FIG. 3 showing an example of a function according to an embodiment of the invention.
    The first interface 14 is designed to receive an alarm signal from the monitoring detector devices 15, the second interface 17 is configured to communicate with an alarm signal control device 12b, and the third interface 18 to communicate with the display unit 19 among other units, where the latter units ( not shown in this figure) will be described below in more detail.
    Referring now to FIG. 3, which shows a fate diagram showing an embodiment of the method.
    To begin with, the evaluation and control unit 12a receives, step 301, an input, in the form of a special alarm L1 caused by a special event, from a monitoring detector device 15, in the form of a camera, via the first interface 14.
    The input may come from a false, or true, event that triggers the camera 15, as shown by a timeline in FIG. 3. All events can be false or true even if they do not appear in this particular. Gur. Thus, the number of events does not matter. Then, the evaluation and control unit 12a, which communicates, step 303, with the alarm signal control device 12b via the second interface 17, step 305, checks a state of the alarm signal, here L1, having at least a first state (herein referred to as "GREEN", or a second condition, here designated "RED"). The evaluation and control unit 12a is typically implemented by a software script (SW) in the VMS server. The alarm signal L1, which here comes from a first camera 15, is set to the second state, RED, step 306 and presented, step 307, to the operator thereof if the state of the input alarm signal L1 was in the first state GREEN, in step 305, the operator handles, typically resets, the alarm signal L1 and a resulting erasure signal STATUS = CLEAN is sent back, step 309, to the evaluation and control unit 12a to restore, step 312, the state of the alarm signal L1 to the first state GREEN, provided the operator has erased the alarm signal L1, step 311. If, on the contrary, the alarm signal L1 was in state RED in step 305, or not deleted, step 311, or if the alarm signal was not alarm signal L1, or the event was in practice no alarm, no alarm is presented to the operator in step 307. In this way, your alarms triggered by the same camera 15, for the same alarm signal L1 of the same event will only be presented once for operation. ören.
    If the operator has not deleted the alarm signal for this particular event L1 and set STATUS = CLEAR for L1, the state of the alarm signal L1 will not be GREEN, steps 311 and 312, and a new alarm from the same camera will not be presented to the operator.
    Alarms L2, L3 etc from other cameras 15 will be handled in the same way as for L1, ie the alarm signal status will be checked and evaluated before any alarm is presented to the operator. An example might be an alarm signal L2 coming from a second camera, which is checked in step 305, which is in the second state RED, i.e. L2 = RED. Then this alarm signal is not presented to the operator in step 307.
    Furthermore, unless the operator has reset the alarm signal L1, then in step 311, since the status is not clear, L1 will not be set to the first state GREEN again but remain in RED.
    Furthermore, if the alarm checked in step 311 is not the first alarm L1 coming from a particular camera, but comes from another camera giving an arman, say a second alarm signal L2, L1 cannot be set to GREEN in step 312 because it does not was the first alarm signal without the second coming from different cameras.
    A major advantage of this embodiment is that it makes it easier for the operator of the monitoring system to focus on the monitoring without many disturbing false alarms, or even countless disturbing true alarms, for one and the same event.
    Another advantage of some of the embodiments shown here is that they are easy to implement for one skilled in the art of computer programming of simple scripts for VMS-SCIVGIII.
    In the drawings and the description, typical embodiments have been described and although specific terms have been used, they are used generically and for descriptive purposes only and are not intended to limit the scope of the invention as set forth in the appended claims.
