2. Description of the Related Art Conventionally, until a predetermined time elapses from an operation of putting a surveillance building in a warning state, a so-called "set operation", a release prohibition time zone for prohibiting the release of the warning state is provided. Immediately after a person leaving the building is extorted by robbery, etc. as soon as he or she exits the surveillance building, he will enter the surveillance building again after canceling the warning. I was reporting an abnormal signal to a central monitoring center at. As a result, even if a burglar breaks in, you will not notice the burglary,
It was possible to report to the central monitoring center, and the central monitoring center could take appropriate measures.

[0003]

In the prior art, when the user notices that he / she left behind in the surveillance building after the set operation, and then performs the release operation to enter the surveillance building again, the user must enter the surveillance prohibition time zone. For example, an abnormality will be immediately reported to the central monitoring center, and emergency responders will rush to the monitored property. In a system in which a large number of monitoring buildings are centrally monitored at remote locations, if a large number of such abnormal reports are generated due to the carelessness of the visitors, unnecessary measures will increase and cause the system reliability to drop. It can be. Also,
In consideration of such circumstances, there is also a problem that the user cannot re-enter the lost property for the lost property during the prohibition time period.

In view of such circumstances, an object of the present invention is to clearly distinguish between a malicious re-entry and a malicious intrusion immediately after a warning state setting operation, and to ensure an accurate alarm operation, thereby making it unnecessary for a false alarm. The object is to provide an alarm device that reduces reliability and improves reliability.

Embodiments of the present invention will be described with reference to FIGS. It should be noted that this embodiment embodies the above-described first invention and second invention at the same time.

FIG. 1 is a diagram showing the arrangement of the equipment of the present invention. In this figure, reference numeral 1 indicates a surveillance building. Reference numeral 2 is connected to a central monitoring center (not shown) via a communication line such as a telephone line or a dedicated line to monitor a building,
The controller which reports to a central monitoring center is shown. Reference numeral 3 denotes an external operation device that is installed outside the surveillance building 1 and that accepts an operation to put the surveillance building 1 in the alert state or the alert release state and sends an operation signal thereof to the controller 2.
Reference numeral 4 indicates an important sensor that monitors a particularly important place in a building such as a vault or a CD machine, and which sensor is an important sensor is preset. Reference numeral 5 indicates a final sensor for monitoring the final entrance / exit that the final exiter passes through when he / she exits the building. Reference numeral 6 indicates a sensor other than the important sensor 4 and the final sensor 5, and is a normal sensor such as an intrusion sensor for monitoring an intruder. These sensors may be general ones as long as they can reliably monitor the monitoring area such as a pyroelectric sensor, a magnet sensor, and an infrared sensor.

Now, the configuration of the controller 2 will be described with reference to FIG. In this figure, reference numeral 21 is a signal from a connected monitoring sensor, a set operation signal / release operation signal from the external operation unit 3, an operation signal from an operation unit 22 described later, a signal from a monitoring center (not shown), etc. 2 shows a signal processing unit that processes the signal. Reference numeral 22 indicates an operation unit for performing a state check operation such as whether or not the sensor arranged in the surveillance building is normal, and a “temporary setting operation” for placing only the important sensor 4 in the surveillance state. Reference numeral 23
Indicates a display unit such as a liquid crystal display, which performs display according to a signal from the signal processing unit 21. Reference numeral 24
Indicates a storage unit including a ROM / RAM that stores necessary information such as a program of this system. Code 25
Indicates a clock unit that measures the current time and inputs the time to the signal processing unit 21. Reference numeral 26 indicates a communication control unit that controls communication with a monitoring center (not shown). Reference numeral 7 indicates a communication line such as a telephone line connecting the monitoring center and the communication control unit 26. Reference numeral 27 is an important sensor 4 for monitoring the inside of the building,
A sensor interface unit that relays signals from the final sensor 5 and a normal sensor 6 such as an intrusion sensor to the signal processing unit 21 is shown. Reference numeral 28 denotes a timer unit that starts measuring a predetermined time when the temporary setting operation is performed from the operation unit 22 and monitors the elapse of the predetermined time. Reference numeral 29 is
The interface part with the external operation device 3 is shown, and the interface part receives the set operation signal or the release operation signal from the external operation device 3 and transmits it to the signal processing part 21.

Next, an operation example of the present invention will be described with reference to FIG. When the controller 2 first accepts that the final leaving person has performed the temporary setting operation on the operation unit 22 (step 105), the timer unit 28 inside the controller 2 is activated (step 110). The timer unit 2
8 is longer than the time required for the last evacuee to leave the building after the temporary set operation, and the time until the danger of being pushed in by a robbery disappears, that is, the last evacuee from the surveillance building Time is up when the time to be able to separate sufficiently passes.

Further, when the timer is activated, only the important sensor 4 is set, and when the important sensor 4 senses a person while the timer is operating (step 115), it means that there is a push. An abnormal signal is sent to the central monitoring center via the communication line 7 (step 15).
0). As a result, even after the temporary setting operation, even if the entire surveillance building is not set, if a robbery or the like forces the user to take them to an important place such as a vault, an abnormal signal will automatically be output to the center. Since it is reported to the monitoring center, no special operation is required if it is pushed in, and it is possible to report to the central monitoring center without being understood by an intimidator.
Since the central monitoring center can grasp the situation, it is possible to take prompt action.

On the other hand, in the case of normal exit when the important sensor 4 is not detected during activation of the timer, the final exiter exits from the final entrance after the temporary setting operation, locks the final entrance door, and then operates the external operating device. 3 performs a set operation, and the controller 2 accepts the set operation (step 12
0). By accepting this set operation, the controller 2 sets the normal sensor 6 and the final sensor 5 to the abnormality detectable state. That is, between the temporary setting operation and this setting operation, the normal sensor 6 and the final sensor 5
No matter how many times it is detected, the signal is canceled by the controller 2 and is not reported to the central monitoring center.
This makes it possible for the last person to leave the property and re-enter the building immediately.

After the setting operation is accepted, when the final sensor 5 or the important sensor 4 is sensed (step 125) or the release operation is detected by the external operating device 3 (step 130), the controller 2 is activated. Sends a "pushing error" to the central monitoring center via the telephone line (step 150). In addition, the normal sensor 6
Detects an abnormality (step 135), "Intrusion abnormality"
Is notified to the central monitoring center via the telephone line (step 160).

When the timer expires after the set operation (that is, YES at step 140).
Is determined), the normal alert state is set (step 145), and the important sensor 4 and the final sensor 5 also
When an abnormality is detected, the abnormality is no longer reported as a "pushing abnormality" but is reported as an "intrusion abnormality" like other normal sensors 6.

In this embodiment, the entire monitoring building is set by the external operation device 3 installed outside, but instead of this, the temporary setting operation by the controller 2, that is, the setting of the important sensor 4 is performed. By operation, activate the delay timer so that exiters can leave the building through the final entrance and exit, and set it automatically when the delay timer times up or the final entrance is locked, whichever comes first. Is also good.

[0017]

As described above, according to the present invention,
Before the entire surveillance building is in the unattended surveillance state, the important sensor that monitors the places where there is a high possibility of being pushed in by robbers etc. is set in the monitoring state, so that it is possible to reliably detect that it is pushed in by robbery. , It is now possible to re-enter the building due to things left behind. As a result, unnecessary measures due to false alarms can be reduced, and as a result, the reliability of the alarm system is improved.
