Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention arranges an intrusion sensor in a security area such as an office, a store, a building, etc., and when the intrusion sensor detects an invasion or a sabotage in the security area, The present invention relates to an alarm device that automatically notifies the security center.

[0002]

2. Description of the Related Art Conventionally, in an office, a store, a building, etc., an intrusion sensor is installed in a security area such as an office so that a security system can be provided when the security area becomes unattended at night or on holidays. There is a security system that sets the alert mode. In this security system, if a thief or the like invades while the security mode is set, the intrusion sensor detects the intrusion and automatically notifies the remote security center.

In this security system, the person who finally exits from the security area (office or the like) (final exiter) sets the security system in the warning mode. The following two methods are usually used to set the security system in the security mode. 1. The last person leaving the security area operates the mode setting device provided outside the security area (outside the office or the like) to set the security system to the warning mode.

2. When the mode setting device is installed in the security area (inside an office or the like) and the final evacuee sets the mode setting device in the caution mode, the final evacuee exits outside the security area. The delay timer that sets the required time in advance operates, and after the delay timer times out, that is,
The security system is automatically set to the warning mode when the last exit seems to have left the security area.

[0005]

However, such an ordinary security system has the following problems. In the above method 1, if an external mode setter is inadvertently operated despite the presence of a legitimate person inside the security area, a warning mode is set and the intrusion sensor detects a legitimate person inside. ,
Send a false alarm to the security center.

In the above method 2, the final exit is
After operating the mode setter in the security area, you may be unable to get out of the security area before the delay timer expires by returning to the office, etc., to retrieve the lost property. In this case, the final exiting person will exit after the security system is set to the warning mode, causing the intrusion sensor installed at the entrance / exit to sense it and sending an erroneous alarm to the security center.

When an erroneous alarm due to such an erroneous operation is sent out, the security company must take unnecessary measures each time. This has led to an increase in security costs and has been a factor that prevents the spread of security systems. The present invention prevents erroneous operation by the user,
An object of the present invention is to provide an alarm device that can prevent false alarms from being sent out.

[0008]

In order to achieve the above-mentioned object, the present invention provides an intrusion sensor in a security area, and when the intrusion sensor detects an invasion or sabotage in the security area, a remote control is performed. In the alarm device for automatically reporting to the security center, a controller installed in the security area, a mode setter installed outside the security area, a timekeeping operation is started based on an operation in the controller, and a predetermined time elapses. A timekeeping means for ending the timekeeping operation later, and a control means for setting the controller to the security mode in the guard area only when the mode setting device is operated during the timekeeping operation of the timekeeping means.

[0009]

When the last exiter leaves the security area for the last time, he / she operates the controller installed in the security area. At the same time, the clocking means is activated. After exiting the security area, the final exit person operates the mode setting device installed outside the security area. If the operation of the mode setting device is performed during the time counting operation before the time counting means times out, the security system is set to the warning mode.

In this alarm device, in order to set the warning mode, both the controller installed inside and outside the security area and the mode setter must be operated, so that the controller installed outside the security area must be operated. Even if it is operated by mistake, the alarm mode is not set and no false alarm is issued. In addition, after the controller inside the security area is operated and the timekeeping means starts the timekeeping operation, if for some reason the last exiter does not operate the mode setter installed outside the security area, the warning mode is set. Is not set to. Therefore, it is possible to prevent the final exiting person from staying in the security area for a long time after operating the controller, thereby causing the intrusion sensor to sense and sending an erroneous alarm to the security center.

As shown in FIG. 2, the controller 1 includes a control unit 11 having a delay timer 17 inside, a confirmation button 13 for the final exit operator to operate, a display unit 12 including a liquid crystal display and a buzzer, and a warning. An alarm transmitter 15 for transmitting a mode signal, an abnormal signal, etc. to the external control center through the communication circuit 3, a mode setter 2
And a signal transmission / reception unit 16 for transmitting and receiving signals.

The mode setting device 2 includes a control unit 21, a card reader unit 23 for reading data stored in an ID card or the like carried by an operator, a display unit 22 composed of a buzzer, a lamp, etc., a controller 1 and signals. A transmission / reception unit 24 that performs transmission / reception is provided. Next, the alert mode setting operation will be described with reference to the flowcharts of FIGS. 3 and 4.

First, the last-exiter checks the tightness of office windows, doors, etc., and presses the confirmation button 13 installed on the controller 1 (step S1). Control unit 11
Inputs the signals of the intrusion sensors 20 to 25 via the sensor input unit 14 to check the state of the intrusion sensor (step S2). At this time, when any of the intrusion sensors 20 to 25 is detecting as in the case where the window is opened (Y in step S3), the control unit 11 causes the display unit 12 to operate.
The location of the sensor or the like being sensed is displayed on the liquid crystal display of (step S4). In this case, the last exiter confirms the displayed part and locks the door.

When the door is completely closed and all the intrusion sensors are in the non-sensing state (N in step S3), a display indicating that the warning mode can be set is displayed on the display unit 12 (step S3). Along with S5, the delay timer 17 built in the control unit 11 is started (step S
6). For the delay timer 17, for example, the time required for the final exiter to exit the final entrance 101 and operate the mode operation device 2 is set.

Along with the operation of the delay timer 17, the controller 1 sends a mode setting permission signal to the mode setting unit 2 (step S7), and the mode setting unit 2 displays on the display unit 2.
The lamp of No. 2 is blinked and the buzzer is repeatedly sounded (step S8). After that, the controller 11 of the controller 1 checks whether or not the mode setter 2 has been operated within the set time of the delay timer 17 (N in step S9) (step S10).

The last exiter is the display unit 1 of the controller 1.
After confirming that the door has been locked by 2, the user exits the office from the final entrance 101 and operates the mode setting device 2 installed outside the office within the operating time of the delay timer 17.
