Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring system for detecting an abnormal situation such as fire, intrusion, gas leak, etc. in a security area such as a building and sending a notification signal to a management center for remote monitoring. Regarding

[0002]

2. Description of the Related Art As an operation mode in such a monitoring system, a warning mode for monitoring a fire, an intrusion, etc. in a security area of a building or the like, a normal user using the building or a security officer to deal with Occasionally, the release mode releases the alert mode, the patrol mode detects an abnormality in the alert area during the alert mode, and the alert mode is released for the guard to check for abnormalities, and the guard performs regular inspections during the alert mode. There is a maintenance mode in which the alert mode is canceled in order to perform.
In addition, a mode in which a guard or the like performs processing by canceling the guard mode, such as a maintenance mode, a patrol mode, or a release mode when the guard releases the guard, is called a coping mode.

In such a monitoring system having various modes, in order to change from the warning mode to the coping mode, a guard operates the mode setting device to set the coping mode. In addition, even after finishing the inspection in the coping mode, the guard operates the mode setting device to set the warning mode.

[0004]

In the conventional monitoring system described above, the inspection action by the guard in the guard area, for example, whether the guard has patroled all the places to be patroled or a course other than a predetermined patrol course is used. It was difficult to manage at a remote management center whether or not a person entered a place.

In addition, in order to prevent the detection device from detecting a guard and sending a false alarm to the management center in the coping mode, communication between the controller and the management center is not performed in principle. The management center could not manage the intrusion of an unacceptable third party into the security area. On the other hand, even in the coping mode, if all abnormal signals from the detection device are sent to the management center, the management center
Abnormal data of high importance in other parts in the alert mode and abnormal data of low importance in parts in the coping mode must be handled at the same level, which makes it difficult to perform efficient monitoring.

Further, in the case where the data accumulated in the coping mode is manually transmitted, the transmission is forgotten, the data amount exceeds the memory capacity in the controller, and the data is automatically erased in the oldest order. Will end up. In addition, communication between the management center and the controller is interrupted, such as when performing maintenance on the main computer of the management center or when an accident such as disconnection occurs in the communication line connecting the management center and the controller in the alarm area. During this time, the management center cannot receive the abnormal signal sent by the detection device, and the abnormal data is sent out from the controller and then sent out without being stored anywhere.

It is an object of the present invention to enable the management center to grasp the abnormal signal detected by the detection device after the fact, even when the communication between the management center and the controller is not performed for the above reason.

[0008]

In order to achieve the above object, the present invention provides a management center, a controller installed in a predetermined warning area and connected to the management center, and the controller connected to the controller. In a monitoring system including a detection device that detects an abnormality in a caution area and a mode setting device that sets a mode in the caution area, in the controller, detection information accumulation for accumulating an abnormality signal of the detection device And a control unit that stores an abnormal signal of the detection device in the detection information storage unit when the mode setting device is set to the coping mode or when there is a request from the management center or the controller. .

[0009]

With the above means, the behavior of the security guard or the intruder in the warning area during the coping mode is detected as an abnormal signal by the detecting device. The abnormal signal is the address of the detecting device detecting the abnormal signal and the detected time. And the like are sequentially stored in the detection information storage unit in the controller. Then, the accumulated detection information is transmitted to the management center at a predetermined timing.

At the management center, from the received detection information,
By knowing the history of actions of security guards and the like, it is possible to ascertain whether or not the security area has been normally managed or whether there is an intruder. In addition, when there is an intrusion into the warning area during the coping mode, the number of abnormal signals detected by the detection device becomes larger than the number of abnormal signals detected by the normal action of the guard. Therefore, by sending data from the controller to the management center at the timing when the number of abnormal signals detected by the detection device exceeds the specified number, it is possible to know that the management center has entered the warning area. You can

Further, since the abnormal data in the coping mode is collectively sent from the controller to the management center, the management center can manage this data differently from the abnormal data in the warning mode, which is of high importance. . In addition, when there is a request from the management center or the controller to store an abnormal signal, the abnormal signal detected by the detection device in the relevant warning area will be detected by the controller along with the address of the detection device that detected it, the detection time, etc. The information is sequentially stored in the information storage unit. Then, the accumulated detection information is transmitted to the management center in response to a transmission request from the management center or the controller.

[0012]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the overall configuration of the monitoring system. Reference numeral 1 is a management center, which manages the signals transmitted from the controller described below for each property and records the history. In addition, remote monitoring is performed using cameras in the security area, and commands etc. are issued to security guards.

Reference numeral 2 is a detection device, which is composed of an intrusion detector, a fire detector, a gas leak detector, an equipment abnormality detector and a transmitter of their abnormality signals, which are installed in the warning area. Connected to the controller by LAN. A mode setting device 3 sets a warning mode, a release mode, a patrol mode, and a maintenance mode.

Reference numeral 4 denotes a controller, which comprises a display unit 5, an operation unit 6, an ID card reading unit 7, an alarm generation unit 8, a signal transmission unit 9 and a control unit 10. The display unit 5 is, for example, a liquid crystal display, and displays the status of modes, the layout of rooms and devices in the guard area and abnormal portions, the operation guidance, and the alarm message.

The operation unit 6 is a key operation unit having a mode setting key, a confirmation key operated by the last-leaved person, and the like. I
The D card reading unit 7 is a unit that reads a card such as a magnetic card or an IC card in which ID data is registered. The accumulation button 14 is a button to be pressed when the abnormal signal from the detection device 2 is not sent to the management center 1 and is to be stored in the memory 12. The send button 15 is a button to be pressed when sending the abnormal signal accumulated in the memory 12 to the management center 1.

The alarm generation unit 8 generates an alarm sound, a message, etc. by a buzzer or voice. The signal sending unit 9 is a unit that sends an abnormal signal of the controller 4, a mode change state, and the like to the management center 1. The control unit 10 has a CPU 1
1, a memory 12 and an interface 13. C
The PU 11 performs various controls of the controller 4. The memory 12, as a detection information storage unit, stores an abnormal signal detected by the detection device 2, an address of the detection device 2, ID data of a guard, and the like, and further stores the number of times of detection of the accumulated abnormal signal. The interface 13 includes the detection device 2,
The mode setting device 3 and the input / output devices from the display unit 5 to the signal transmission unit 9 are connected to the CPU 11.

The controller 4 is also connected to the management center 1 by a contact line such as a telephone line 14. Although only one controller 4 is shown in the drawing, a plurality of controllers 4 are usually connected to one management center. Next, the operation of the monitoring system of this embodiment will be described using the flowcharts of FIGS. 2 and 3. The operations of the surveillance system of the present embodiment in the alert mode and the release mode are performed in the same manner as in the conventional surveillance system, and therefore the description thereof is omitted here.

FIG. 2 is a flow chart for explaining the operation in the coping mode. The guard inserts a coping ID card into the ID card reading unit 7 of the controller 4 when performing an abnormal inspection or a periodic inspection. That I
If the D card is correct, switching from the warning mode to the coping mode of the patrol mode or the maintenance mode is automatically set (step S1). When the mode is switched, the newly set mode is displayed on the display unit 5, and at the same time, the management center 1 is notified that the mode has been switched.

Incidentally, instead of inserting the ID card, the personal identification number can be entered. Further, the key operation of the mode setting device 3 may be performed after inserting the ID card. Even if this coping mode is set, the detection device 2 is in a state of being able to detect an abnormality in the warning area and send an abnormality signal, and the intrusion detector detects the abnormality of the guard or other person. When the detection device 2 detects an abnormality (step S2
Y), the detection device 2 inputs the detection information including the abnormal signal and its own address to the controller 4 (step S3). This detection information is stored in the memory 1 in the control unit 10.
2 are sequentially stored (step S4). In addition, the number of times of detection of an abnormal signal is counted and stored in the same memory 12.

At the same time, the display unit 5 displays the abnormal portion and the alarm message, and the alarm generation unit 8 generates a buzzer or an audible alarm sound or message. The detection information accumulated in the memory 12 is sent to the management center 1 at a predetermined timing. In the present embodiment, as the timing, when the mode is switched by the mode setting device 2 (Y in step S5) and when the number of times of detection by the detection device 2 is equal to or more than the set value (Y in step S6).
And both. Each time the detection device 2 detects an abnormality, the detection information is accumulated in the memory 12 until the timings as described above are reached, and the detection count is incremented by +1.

Here, when an intruder enters the warning area while the coping mode is set, or when a guard moves off a predetermined course and acts, the number of times the detection device 2 detects an abnormality is determined. Will increase. Therefore, when the number of detections exceeds a predetermined value (Y in step S6), it is considered that there is an intruder, and the accumulated data is sent to the management center 1 (step S7). In this case, the alarm generation unit 8 of the controller 4 may issue an alarm to the security guard.

In the mode setting device 2, the stored data is also sent to the management center 1 at the timing when the coping mode is switched to another mode, for example, the warning mode (Y in step S5) (step S7). The switching from the coping mode to the alert mode is performed by the guard setting the alert mode by operating the mode setting device 2 after completing the patrol or inspection. The switching from the coping mode to the release mode is performed by a user such as a building going to work the next morning and operating the mode setting device 2 to set the release mode.

In a security system that does not have a patrol mode, the security staff sets the release mode and performs a countermeasure and a recovery operation. When sending the accumulated data to the management center 1, the control unit 10 adds various ID codes such as the address of the detection device, the detection order, and the property name to the abnormal signal.
In the controller 4, the contents of the memory 12 may be cleared after sending the accumulated data.

In the management center 1, it is possible to know the device number of the detection device, the detection order, the number of times of detection, the start / end time of the coping mode, etc. for each property from these ID codes. Therefore, in the management center 1, when an intruder sends out abnormal data after the number of times of detecting an abnormal signal exceeds a predetermined number, an immediate action is taken. As for other abnormal data of low importance, the data received during the coping mode is managed as a patrol location and a history of detection device issuance.

In the management center 1, by examining this history at a later date, it is possible to know which user has detected which detection device, which part of the security guard should be clarified, and the operation status of the detection device should be grasped. can do. In this way, for data of low importance during coping mode,
It is possible to perform management different from the abnormal signal during the warning mode of high importance.

FIG. 3 shows the management center 1 or the controller 4.
5 is a flowchart illustrating an operation in response to a storage request from the. When maintenance of the computer of the management center 1 is performed, or when the communication line is disconnected, a request signal is sent from the management center 1 or the accumulation button 14 of the controller 4 is operated (step S11), the detection device is detected. When 2 detects an abnormality (Y of step S12), the detection device 2 inputs the detection information including the abnormality signal and its own address to the controller 4 (step S13). This detection information is sequentially stored in the memory 12 in the control unit 10 (step S14).

As described above, when the communication between the management center 1 and the controller 4 is restored and the transmission request signal is sent from the management center 1, the detection information accumulated in the memory 12 is
Alternatively, when the send button 15 of the controller 4 is operated (step S15), the stored data is sent to the management center 1 (step S16). The management center 1 can know which detection device was detected by which user at which time by examining the stored data that has been sent, and the embodiments of the present invention have been described above.
The present invention is not limited to this embodiment, but can be variously modified within the scope described in the claims.

For example, when an emergency such as a fire is detected in the area where the coping mode is set, unlike the data that does not require an emergency, the detection information is immediately sent to the management center without being accumulated. You can also do it.
Further, in the flow chart of FIG. 2, when the detection information accumulated from the controller is sent to the management center, in the above embodiment, it is performed at three timings of switching from the coping mode to another mode and increasing the number of detections. The detection information is sent at the timing when any one of them occurs, but the detection information is sent at any one or two of these timings. You can also

[0029]

According to the present invention, the abnormal signal detected by the detection device can be grasped in the management center even when the communication between the management center and the controller is temporarily stopped.
