Description

The present invention relates to a monitoring device, a control device and a monitoring method.

Today, for example, a sensor is installed in a monitored object such as a house, a building, a vehicle, or a predetermined facility. 2. Description of the Related Art Machine security systems are known that remotely monitor objects to be monitored by transmitting an alarm signal from a provided control device to a remote monitoring device. In this machine security system, when a sensor detects theft of an object to be monitored or an equipment malfunction, the control device transmits an alarm signal to a monitoring device installed in a remote monitoring center via a communication line. When the monitor receives the alarm signal from the controller, it displays the alarm signal on the monitor. When the observer at the monitoring center confirms the displayed alarm signal, he instructs the guard to go to the location of the object to be monitored (instruction to dispatch to the site). As a result, the security guard goes to the location of the object to be monitored and confirms the safety of the object to be monitored.

Here, in the case of a mechanical security system that remotely monitors objects to be monitored using a vibration sensor, the vibration sensor detects vibration and generates an alarm signal. There is a problem that it reacts and many false alarms are issued.

For this reason, in the monitoring device disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-115091), when the occurrence of an earthquake is detected, an alarm signal is sent from the vibration sensor provided on the monitored object to the monitoring center. False alarms are reduced by controlling not to do so.

JP 2003-115091 A

However, the technology disclosed in Patent Document 1 does not transmit an alarm signal based on the detection signal from the vibration sensor during a disaster such as an earthquake or typhoon. If it continues, there is a problem that it is suppressed as an erroneous alarm during that period, and the alarm signal is not transmitted, so that the monitoring device cannot perform sufficient monitoring. In addition, there is a possibility that the alarm signals, which are generated in large numbers in this way, include true information, for example, that announcing the occurrence of a fire. For this reason, it is necessary to accurately discriminate between true and false reports so that they can be dealt with.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. The object is to provide an apparatus and a monitoring method.

In order to solve the above-described problems and achieve the object, the present invention detects the occurrence of an abnormality in a monitored object in which a control device is installed based on an alarm signal transmitted from a control device installed in the monitored object. A monitoring device for monitoring, wherein the alarm signal includes at least information indicating a sensor that has detected an abnormality and information indicating whether or not a disaster has occurred, and when the monitoring device receives the alarm signal, the alarm signal Based on the included information indicating the presence or absence of a disaster and information indicating the sensor that detected the abnormality, the degree of urgency of the received warning signal is determined and displayed.

Various sensors 21 and a disaster detection unit 22 are connected to the control devices 1-1 to 1-n. Examples of the sensor 21 include a vibration sensor installed on a window or the like to detect vibration, a fire sensor to detect heat and smoke, and an image sensor to detect an intruder from an image. As an example, the disaster detection unit 22 includes a circuit for receiving emergency earthquake early warnings such as a mobile phone network, a seismic intensity meter, an acceleration sensor, an image analysis circuit, and the like for detecting earthquakes. Moreover, as the disaster detection unit 22, an anemometer, a vibration sensor, a sound sensor, and the like are provided for wind detection. Moreover, as the disaster detection unit 22, a water leakage sensor, a water level gauge, an image analysis circuit, and the like are provided for detecting inundation. Furthermore, as the disaster detection unit 22, an inclination sensor, an image analysis circuit, and the like are provided for landslide disaster detection. The sensor 21 transmits a detection signal indicating that the detection target has been detected to the alarm determination units 31 of the connected control devices 1-1 to 1-n. Further, the disaster detection unit 22 transmits a disaster detection output indicating detection of the detection target to the disaster determination unit 32 of the connected control devices 1-1 to 1-n.

Based on the disaster detection output output by the disaster detection unit 22, the disaster determination unit 32 determines the presence or absence of a disaster, "disaster type" such as an earthquake, strong wind, flood, tsunami, and landslide, as well as a seismic intensity of 5 and a flood of 1 m. , large damage, small damage, etc.

The disaster detection unit 22 and the disaster determination unit 32 may be integrated with the control devices 1-1 to 1-n, or may be provided separately for each function.

On the other hand, the center device 2 is connected to the monitor terminal 51 , the guard terminal 52 and the display section 53 via the communication section 42 . The observer terminal 51 is a terminal device for the observer to monitor and guard, is connected to the center device 2, and receives from the center device 2 an alarm signal to be responded to by the observer and the sender of the alarm signal. A terminal device that displays information about an object to be monitored where the control device is installed, receives an input such as an instruction from the observer to the security guard who is directed to the object to be dispatched to the site, and transmits the input to the sensor device 2 is. The guard terminal 52 is a portable terminal device possessed by a security guard, which displays an on-site dispatch instruction or the like from the center device 2, and also displays the result of treatment for the on-site dispatch instruction in accordance with the security guard's input operation. 2. The display unit 53 is a large monitor device or the like on which disaster information or the like received from the center device 2 is displayed. When a disaster occurs, the observer confirms the scale of the disaster, area, etc. from the contents displayed on the display unit 53 . Note that the surveillance terminal 51 and the guard terminal 52 may be connected to the center device 2 via the communication line 3, as indicated by the dotted block in FIG.

(Configuration of control device)
Each of the control devices 1-1 to 1-n has a control section 11, a communication section 12 and a storage section 13. FIG. The communication unit 12 communicates with the center device 2 and transmits an alarm signal, a restoration signal, and the like to the center device 2 . The storage unit 13 stores alarm processing programs for the control devices 1-1 to 1-n. The control unit 11 functions as an alarm determination unit 31 , a disaster determination unit 32 and a transmission message generation unit 33 by executing an alarm processing program stored in the storage unit 13 .

When functioning as the alarm determination unit 31 , the control unit 11 determines based on the sensor output of the sensor 21 whether an abnormality such as a fire or illegal entry has occurred. When the control unit 11 functions as the disaster determination unit 32 , based on the detection output from the disaster detection unit 22 , the control unit 11 determines whether a disaster such as an earthquake or strong wind has occurred, the type of disaster, the level of the disaster, and the like. In addition, when the control unit 11 functions as the transmission message generation unit 33, when the alarm determination unit 31 determines that an abnormality has occurred, the "type of abnormality that occurred" and the determination result of the disaster determination unit 32 A warning signal is generated that includes "disaster occurrence details" such as the presence or absence of a disaster occurrence, disaster type, and disaster level. Further, when it is determined that the output of the sensor 21 has changed from the state in which an abnormality has occurred to the state in which no abnormality has occurred, a recovery signal indicating that the abnormality has ceased to be detected is generated. The alarm signal and restoration signal are transmitted to the center device 2 via the communication line 3 by the communication section 12 .

In this example, the control unit 11 executes the alarm processing program to realize the alarm determination unit 31, the disaster determination unit 32, and the transmission telegram generation unit 33 by software. However, all or part of these may be realized by hardware such as an IC (Integrated Circuit).

In addition, the alarm processing program may be provided by being recorded in a computer-readable recording medium such as a CD-ROM or a flexible disk (FD) as file information in an installable format or an executable format. Also, the alarm processing program may be provided by being recorded on a computer-readable recording medium such as a CD-R, a DVD (Digital Versatile Disk), a Blu-ray (registered trademark) disk, or a semiconductor memory. Also, the alarm processing program may be provided in the form of being installed via a network such as the Internet. Also, the alarm processing program may be provided by being pre-installed in a ROM or the like in the device.

(Configuration of center device)
The center device 2 has a control section 41 , a communication section 42 and a storage section 43 . The communication unit 42 communicates with each of the control devices 1-1 to 1-n, the observer terminal 51 and the guard terminal 52 via the communication line 3, and issues alarm signals, recovery signals, instructions to dispatch to the site, and measures. Send and receive results, etc. An alarm processing program for the center device 2 is stored in the storage unit 43 . In addition, the storage unit 43 is provided with a security information database (security information DB: an example of a database) corresponding to a storage area for security information.

The security information DB stores various information based on past monitoring security, such as customer information for each monitored object, alarm history, false alarm history at the time of disaster, current state, treatment results, and instructions to security guards. there is

By executing the alarm processing program for the center device 2 stored in the storage unit 43, the control unit 41 controls the urgency determination unit 61, the summary generation unit 62, the observer notification unit 63, the treatment result input unit 64, It functions as a display control section 65 , a disaster area analysis section 66 , a disaster analysis section 67 and a false alarm analysis section 68 .

When functioning as an urgency determination unit 61, which is an example of the determination unit, the control unit 41 determines the urgency level and true/false alarm of the received warning signal based on the presence or absence of a disaster. Further, when functioning as the summary generating unit 62, the control unit 41 generates an alarm signal determined to be a false alarm or a possibility of a false alarm from the same control devices 1-1 to 1-n within a preset monitoring time. When a predetermined number or more of alarm signals are received (alarm signals occur frequently), the content of each alarm signal is grouped into one (or a small number) to generate a summary of general information. Note that the summary generation unit 62 may be implemented on the side of the control devices 1-1 to 1-n.

The received alarm signal and the generated comprehensive information are notified to the observer terminal 51 by the observer notification unit 63 . The monitor terminal 51 displays the notified alarm signal, general information, and information about the object to be monitored where the controllers 1-1 to 1-n, which are the senders of these alarm signals and the like, are installed. In addition, according to the operation of the surveillance staff who confirms this display, an instruction to dispatch to the site is input to the guards. The center device 2, to which the on-site dispatch instruction is input from the surveillance terminal 51, stores the contents of the instruction in the security information DB of the storage unit 43, and monitors the security terminal 52 possessed by the security guard who directs the object to be monitored. Send a field dispatch order containing the information of the object. At this time, the guard terminal 52 is notified of the situation of the object to be monitored, which is estimated based on the general information and alarm signals from the control devices 1-1 to 1-n installed in the object to be monitored. For example, when an emergency button is operated during a flood disaster, a notification is made including the details of the disaster, such as notifying a security guard that the situation is dangerous due to flooding and calling for attention.

As a result, it is possible to notify the monitoring staff of frequently occurring alarms in an easy-to-understand manner, and to prevent the inconvenience of being notified of a large number of warnings to the monitoring staff and the like due to the frequent occurrence of alarms in the event of a disaster, making it difficult to respond. The general information (summary information) generated by summarization is displayed on the monitor terminal 51 according to the degree of urgency, and is also stored in the security information DB of the storage unit 43 . Furthermore, it is possible to grasp the disaster situation of the guard target and give appropriate instructions to the guards.

In addition, the control unit 41 receives, via the communication unit 42, the treatment result input by the security guard who received the instruction from the security terminal 52, and when functioning as the treatment result input unit 64, the urgency determination unit 61 automatically inputs the processing result for the alarm signal determined to be a false alarm into the security information DB of the storage unit 43 . Further, when the control unit 41 functions as the treatment result input unit 64, the treatment results received by the communication unit 42 from the guard terminal 52 are summarized as described above, and the treatment results corresponding to the summary information generated are displayed. , it is input and processed in the alarm information DB as the action result of each alarm signal before summarization. As a result, it is possible to reduce the labor required for observers, etc., to input the results of actions taken in response to a large number of warnings that occurred during a disaster.

In addition, when the control unit 41 functions as the display control unit 65, the control unit 41 also performs a disaster area analysis unit 66 (to be described later) and a The display unit 53 is controlled to display the analysis result or the prediction result of the analysis unit 67 or an image of the situation of the area. Further, when functioning as the disaster area analysis unit 66, the control unit 41 predicts the disaster area and damage. Further, when functioning as the disaster analysis unit 67, the control unit 41 predicts damage caused by a disaster. In addition, when functioning as the false alarm analysis unit 68, the control unit 41 considers and proposes the installation location of the sensor, the type of the sensor, etc. based on the installation location of the malfunctioning sensor, etc., and reduces the recurrence of the malfunction. Plan.

In this example, the control unit 41 executes an alarm processing program for the center device 2, thereby implementing the urgency determination unit 61 to the false alarm analysis unit 68 in terms of software. However, all or part of these may be realized by hardware such as an IC (Integrated Circuit). Also, in this embodiment, the center device 2 is described as an integrated device, but the present invention is not limited to this, and a part of the device may be separated.

In addition, the alarm processing program may be provided by being recorded in a computer-readable recording medium such as a CD-ROM or a flexible disk (FD) as file information in an installable format or an executable format. Also, the alarm processing program may be provided by being recorded on a computer-readable recording medium such as a CD-R, a DVD (Digital Versatile Disk), a Blu-ray (registered trademark) disk, or a semiconductor memory. Also, the alarm processing program may be provided in the form of being installed via a network such as the Internet. Also, the alarm processing program may be provided by being pre-installed in a ROM or the like in the device.

(Operation of control device)
Next, the operation of the controllers 1-1 to 1-n in such a monitoring system will be explained using the flowchart of FIG. In the flow chart of FIG. 2, in step S1, the alarm determination unit 31 determines whether or not an abnormality has occurred based on the output from the sensor 21. FIG. When the alarm determination unit 31 detects the occurrence of an abnormality (step S1: Yes), the disaster determination unit 32 determines whether a disaster has occurred, the disaster type, and the disaster level based on the disaster detection output acquired from the disaster detection unit 22. is determined (step S2). At this time, the disaster judgment unit 32 may make judgments based on a plurality of factors, such as judging the disaster type and disaster level based on both the received earthquake early warning and the detection output of the building seismic intensity meter. can make an accurate judgment.

That is, when an earthquake occurs, for example, the alarm determination unit 31 detects the occurrence of an abnormality (intrusion) alarm based on the detection output of a vibration sensor for detecting breakage of a window, which is one of the sensors 21. (Step S1). The disaster determination unit 32 indicates the occurrence of an earthquake (disaster type) detected by a circuit for receiving an emergency earthquake early warning or a seismic intensity meter, which is one of the disaster detection units 22, at the timing when the occurrence of this warning is detected. Information and information indicating a disaster level such as a seismic intensity of 5 are acquired, and the disaster type and disaster level are determined (step S2).

Next, the transmission telegram generation unit 33 generates an alarm signal containing “contents of disaster occurrence” such as whether or not a disaster has occurred, disaster type, and disaster level determined by the disaster determination unit 32 in addition to the abnormality type, sensor number, etc. Generate (step S3). The communication unit 12 transmits an alarm signal including the "disaster occurrence content" to the center device 2 via the communication line 3 (step S4). On the side of the center device 2, the urgency of the warning is determined based on the "disaster occurrence content" of the warning signal, as described below.

(Operation of center device)
Next, the operation of the center device 2 will be described with reference to the flow chart of FIG. In the flowchart of FIG. 3, in step S21, the urgency determination unit 61 sends an alarm signal including the above-described "disaster occurrence content" from the control devices 1-1 to 1-n to the communication unit 42 (an example of the receiving unit). received. Then, when this warning signal is received (step S21: Yes), in step S22, the urgency determination unit 61 determines the urgency of the warning based on various information such as "details of disaster occurrence" included in the warning signal. judge. That is, the urgency determination unit 61 determines the contents of the disaster occurrence (presence or absence of disaster occurrence, disaster type, disaster level) of the alarm signal received from the control devices 1-1 to 1-n, the alarm contents (fire, gas leak, intrusion, Equipment abnormality, etc.), the object to be monitored, the history of past false alarms stored in the security information DB, etc., determine the urgency of the alarm.

FIG. 4 is a flow chart showing the detailed flow of the urgency determination operation in the urgency determination unit 61. As shown in FIG. When the urgency determination unit 61 shifts to the urgency determination operation, first, in step S41, it determines whether or not a disaster has occurred based on the information indicating whether or not a disaster has occurred, which is included in the details of the disaster occurrence in the received warning signal. . In this step S41, the determination that there is no disaster means that the received alarm signal is not an alarm signal based on a disaster, but a true report indicating that some kind of abnormal situation has occurred in the object to be monitored. means that

Therefore, when the urgency determination unit 61 determines that there is no disaster in step S41, the process proceeds to step S43 and determines that the urgency is "high (normal)" true news. In this case, the observer notification unit 63, which is an example of a notification unit, notifies the observer terminal 51 of the occurrence of an alarm.

On the other hand, if it is determined in step S41 that the received warning signal may have been caused by a disaster (disaster exists), the urgency determination unit 61 advances the process to step S42. In step S42, the urgency determination unit 61 performs false alarm determination of the received alarm signal.

In this false alarm determination, the urgency determination unit 61 determines the disaster occurrence content (disaster type, disaster level) of the received alarm signal, the alarm content (fire, gas leak, intrusion, equipment abnormality, etc.), as well as the security information in the storage unit 43 The urgency of the warning is determined based on the sensor type, the object to be monitored, and the history of past false alarms stored in the security information DB stored in the information DB.

FIG. 5 is an example of past false alarm history. The past erroneous alarm history of the object to be monitored is the history of erroneous alarms treated as the cause of erroneous alarms as a result of on-site treatment in the past.

Specifically, as shown in FIG. 5, the history of past false alarms includes the date and time of occurrence of false alarms (year, month, day, hour, minute, second), security targets (areas where monitored objects exist, etc.), disaster details (disaster type), Various information such as earthquake, strong wind, flood, tsunami, landslide, etc., disaster level: numerical value such as seismic intensity, flood amount, degree (large, medium, small), etc.) are stored. In addition, as past false alarm history, alarm content (type: fire, gas, intrusion, equipment abnormality, etc.), sensor type (sensor number, sensor model, sensor method, sensor sensitivity, etc.), cause (false alarm, true alarm, etc.) and various information such as the contents of measures (sensor installation location change, sensor replacement, sensor sensitivity change, etc.) are stored.

The urgency determination unit 61 refers to these false alarm histories to determine the urgency of the alarm as follows. That is, in step S42, the urgency determination unit 61 determines that the "disaster occurrence content" included in the alarm signal indicates that a disaster has occurred and that the alarm is a life-threatening alarm such as a fire or gas leak. If so, in step S44, it is determined as "high (disaster)", which indicates that the alarm signal is issued at the time of a disaster but has a high degree of urgency.

Further, in step S42, the same alarm is issued as a false alarm in the past disaster, and the alarm signal is from the monitored object for which on-site measures such as changing the sensor installation location or replacing the sensor have not been performed. In the case of an alarm signal from , the urgency determination unit 61 determines that the urgency is low (false alarm due to disaster), which indicates that the urgency is low in step S46, because there is a high possibility of a false alarm due to a disaster.

Further, in step S42, if the content of the disaster occurrence and the type of sensor that detected the abnormality match conditions that may cause false alarms (detection of a vibration sensor during an earthquake or strong wind, etc.), the degree of urgency determination unit 61 may be a false alarm due to a disaster, so in step S45, it is determined as "medium (possibility of a false alarm due to a disaster)" indicating that the urgency of the alarm signal is medium.

When the determination of the degree of urgency of the alarm signal is completed, the process proceeds to step S23 in the flowchart of FIG. In step S23, the observer notification unit 63 determines whether or not the determination result of the urgency level of the alarm in step S22 indicates that the urgency level is high. If the determination result indicates that the degree of urgency is high (step S23: Yes), in step S24, the observer notification unit 63 notifies the observer terminal 51 of the content of the generated alarm, and the observer terminal 51 receives the received alarm. Display the content of the alarm on its own monitoring screen.

FIG. 6 shows a display example of a monitor screen monitored by a monitor. As shown in FIG. 6, the monitoring screen displays the urgency of the alarm, the customer number, the area number where the object to be monitored exists, the name of the security destination, the name of the area, the outline of the received alarm signal, general information, and the disaster information. The disaster information, etc. showing the contents of is displayed.

Among these, the degree of urgency is displayed as "high (true report)", "high (disaster)", "low (false report)", "medium (probability of false report)", and the like. As the customer number, a unique number assigned to each customer such as "000001", "000002", etc. is displayed. As the name of the security destination, the name of the store to be guarded, the name of the owner, etc., such as 〇〇 bank, Mr. □□'s residence, etc., are displayed. As the area name, the location where the sensor 21 is installed, such as a vault or a conference room, is displayed.

As the received signal, the time when the sensor 21 detected the abnormality and the details of the abnormality are displayed, such as "01:00, intrusion" and "01:00, emergency". As the summary information, as will be described later, when general information is created as a summary of alarm signals due to frequent occurrence of alarm signals, this general information is displayed. As the disaster information, the content of the disaster that has occurred is displayed, such as the occurrence of a sediment disaster, seismic intensity of upper 6, and the like.

The monitor terminal 51 displays on the monitor screen the notified alarm signal, general information, and information about the object to be monitored where the control devices 1-1 to 1-n, which are the senders of these alarm signals, are installed. Then, the monitor is notified of the occurrence of the abnormality (step S24). In addition, according to the operation of the surveillance staff who confirms this display, an instruction to dispatch to the site is input to the guards.

The center device 2, to which the on-site dispatch instruction is input from the surveillance terminal 51, stores the contents of the instruction in the security information DB of the storage unit 43, and sends the observation target to the security terminal 52 possessed by the security guard who directs the surveillance target. Send a field dispatch order containing information about the object. At this time, the guard terminal 52 is notified of the situation of the object to be monitored, which is estimated based on the general information and alarm signals from the control devices 1-1 to 1-n installed in the object to be monitored.

The security guard who receives the instruction to go to the scene inputs the content of treatment and the like from the security guard terminal 52 after confirming the situation of the object to be monitored. Then, the guard terminal 52 transmits the treatment result including the treatment contents to the center device 2 .

When the action result input unit 64 of the center device 2 receives the action result from the guard terminal 52 through the communication unit 42 (step S25: Yes), the action result corresponding to the alarm signal generated in the security information DB of the storage unit 43 is entered. etc. (step S26) to terminate the processing for the alarm signal. In step S25, if the treatment result cannot be received (step S25: No), the process waits until the treatment result is received.

Next, when it is determined in step S23 that the urgency of the alarm signal is not high (step S23: No), it is determined whether the urgency of the alarm signal is medium (step S27). If the degree of urgency is medium (step S27: Yes), the process proceeds to step S28, and the urgency determination unit 61 determines whether or not a predetermined number or more of the same alarm signals have been received (frequent alarms) within the preset monitoring time. determine whether If the alarm signal is single or few (step S28: No), the process proceeds to step S24, the observer notification unit 63 notifies the observer terminal 51 of the contents of the generated alarm, and the observer terminal 51 receives The content of the alarm is displayed on its own monitoring screen.

In step S28, if a predetermined number or more of the same alarm signals have been received within the preset monitoring time (step S28: Yes), in step S29, the summary generating unit 62, for example, as shown in FIG. As shown in , general information is generated by summarizing frequently occurring alarms.

Specifically, the example shown in FIG. 7 is an example in which the center device 2 receives a large number of facility alarms between 19:00:00 and 19:01:00 due to the occurrence of an earthquake. When receiving such a large number of alarm signals, the summary generation unit 62 generates general information summarizing into one, for example, "19:00 to 19:01, equipment alarms occur frequently when an earthquake occurs (30 cases)". do.

Although the information form of the comprehensive information is arbitrary, it is preferable to include the time range of a large number of summarized alarms such as 19:00 to 19:01 and the number of frequently occurring alarm signals such as 30. Also, the content of the disaster such as an earthquake with a seismic intensity of upper 5 may be included.

The observer notification unit 63 notifies the observer terminal 51 of general information generated by summarizing a large number of alarm signals (step S29). As a result, a large number of alarms are notified to the monitor terminal 51, and the inconvenience of the monitor having difficulty in responding can be prevented.

Note that the observer notification unit 63 may notify the observer terminal 51 of general information generated by summarizing a large number of alarm signals after notification of an alarm with a high degree of urgency is completed. In this case, the observer or the like can recognize the reception of the alarm signal from the general information after taking action against the alarm with high urgency, thereby preventing the trouble that the observer and the security guard are difficult to deal with.

In addition, the observer terminal 51 that has received the notification from the observer notification unit 63 displays this comprehensive information on the monitor screen as shown in FIG. The example shown in FIG. 6 is an example in which comprehensive information is generated and displayed on the monitoring screen between 1:00 and 1:01, with the window sensor frequently occurring (5 times). As a result, the surveillance staff can recognize that the alarm signals frequently issued between 1:00 and 1:01 may be false alarms caused by the earthquake.

The monitor terminal 51 displays on the monitoring screen the notified general information and the information about the monitored objects where the control devices 1-1 to 1-n, which are the transmission sources of the general information, are installed, and informs the monitor of the abnormality. Notify the occurrence of In addition, according to the operation of the surveillance staff who confirms this display, an instruction to dispatch to the site is input to the guards.

The center device 2, to which the on-site dispatch instruction is input from the surveillance terminal 51, stores the contents of the instruction in the security information DB of the storage unit 43, and sends the observation target to the security terminal 52 possessed by the security guard who directs the surveillance target. Send a field dispatch order containing information about the object. At this time, the guard terminal 52 is notified of the situation of the object to be monitored, which is estimated based on the general information and alarm signals from the control devices 1-1 to 1-n installed in the object to be monitored.

The security guard who receives the instruction to go to the scene inputs the content of treatment and the like from the security guard terminal 52 after confirming the situation of the object to be monitored. Then, the guard terminal 52 transmits the treatment result including the treatment contents to the center device 2 .

When the action result input unit 64 of the center device 2 receives the action result from the guard terminal 52 through the communication unit 42 (step S30: Yes), the action result corresponding to the generated alarm signal to the security information DB in the storage unit 43 is entered. etc. (step S31) to terminate the processing for the alarm signal. The input of the action content and the like in step S31 is individually input for a large number of alarm signals before being summarized as general information. In step S30, if the treatment result cannot be received (step S30: No), the process waits until the treatment result is received.

FIG. 8 is an example of a treatment result input to the security information DB by the treatment result input unit 64 . In the example of FIG. 8, 30 alarms were generated frequently, but since there is a possibility that they were false alarms caused by an earthquake, a small amount of information such as "Treatment result: no abnormality, cause: earthquake" It is the example which showed inputting to security information DB.

It should be noted that the input of such a treatment result may be performed by the observer to the observer terminal 51 . Even if the monitoring is performed by an observer, the work of inputting a small amount of summarized information described above can be completed, so that the labor required for inputting the treatment results can be greatly reduced.

Next, when it is determined in step S27 that the degree of urgency is not medium (step S27: No), in step S32, the degree of urgency determination unit 61 determines whether or not the recovery signal has been received within a certain period of time.

If the restoration signal is received within the fixed time (step S32: Yes), it means that the received alarm signal is a false alarm. Therefore, in step S33, the observer notification unit 63 does not notify the observer terminal 51 of an alarm, and the action result input unit 64 receives the alarm content and recovery signal, and the action result (on-site action due to false alarm due to disaster) None) is stored in the security information DB, and the process ends.

Note that, in this example, if a recovery signal can be received within a certain period of time for an alarm signal whose urgency is not high or medium (step S32: Yes), the observer notification unit 63 sends the observer terminal 51 It was decided not to notify the details of the warning. However, the display of the alarm signal for which the recovery signal has been received within a certain period of time on the monitoring screen may be performed after the completion of the display of the alarm of high urgency.

In addition, when the restoration signal is received within a certain period of time (step S32: Yes), the observer individually inputs the action result of the alarm from the observer terminal 51, receives the alarm content and the restoration signal, and receives the action result (disaster No on-site action due to false alarm) may be stored in the security information DB and the process may be terminated (step S33).

On the other hand, if the recovery signal is not received within a certain period of time (step S32: No), although there is a high possibility that it is a false alarm and the degree of urgency is low, there is a possibility that some kind of abnormality has occurred. It is necessary to dispatch security guards, etc. In this case, the observer notification unit 63 proceeds to step S28. As a result, the observer takes measures such as directing a security guard to the site based on the alarm signal displayed on the monitor screen.

Here, when the disaster area analysis unit 66 of the center device 2 receives disaster warnings from a plurality of guard destinations, for example, it predicts the disaster area and the damage from the addresses of the guard destinations. The display control unit 65 displays the area of the disaster and the predicted damage situation on the display unit 53, so that the observer can be notified of the damage situation of the wide-area disaster. By notifying the security guard terminal 52 of the disaster situation, the security staff can also be informed of the disaster situation and alerted.

In addition, the disaster analysis unit 67 of the center device 2 predicts the degree of danger such as building collapse from the location of sensor operation due to an earthquake, and also predicts failure such as deterioration of customer equipment from the frequent occurrence of equipment abnormalities due to an earthquake. By notifying the observer terminal 51 of the predicted degree of danger, failure prediction, or the like by the observer notification unit 63, the observer can call the security guard's attention. By notifying the security guard terminal 52 of the disaster situation, the security staff can also be informed of the disaster situation and alerted.

Further, the false alarm analysis unit 68 of the center device 2 proposes a change in the sensor installation location or the sensor type based on the installation location or sensor type of the sensor that malfunctioned at the time of the disaster. For example, if a false alarm is issued from the door sensor on the first floor every time an earthquake occurs, the false alarm analysis unit 68 displays the change in the installation location of the first floor door sensor on the display unit 53 via the display control unit 65. suggest. This can reduce the occurrence of false alarms.
