The security alarm display device 1 includes a security sensor 2
, A district display device 10 for displaying an abnormal district based on the above signals, a numeric keypad 11 for performing various operation inputs, and a display device 12 for displaying input data input to the numeric keypad 11.
And a security input device 13 for inputting a security status for each district by a card reader or the like.

The security alarm display device 1 usually monitors a security alarm area based on a detection signal from the security sensor 2 and, when an abnormality occurs, displays a security area or the like on the area display device 10 to generate an alarm. In addition, based on the security status change (start or release of security status) data for each area set and input from the security input device 13, the controlled devices 3 such as door locking, lighting devices, elevators, and various display devices are controlled. Outputs a control signal to control. For example, when all tenant stores on the seventh floor of a certain building are in a security start state (closed), the lighting device on this floor is turned off, the doors leading to this floor are locked, and the operation of the elevator is stopped. It is.

As described above, since the security state of each area input from the security input device 13 and the control relationship between the controlled device 3 and the controlled equipment 3 are different depending on the installed equipment, a logical expression is input from the numeric keypad 11 when the equipment is installed, and this logical expression is input. The control is performed based on.
The data (logical formula) input from the ten keys 11 is displayed on the display device 12 and can be input while confirming whether there is no mistake in the input.

FIG. 2 is a block diagram showing one embodiment of the security alarm display device 1. As shown in FIG. The security alarm display device 1 includes a central processing unit 100 such as a microprocessor, a storage device 101 that stores programs, data, and the like, and stores input data (logical formula). A transmission control device 103 for transmitting and receiving signals to and from a security sensor in a guard area based on the security input device 109 that is connected to the central processing unit 100 via an input interface 104 and inputs a maintenance state for each area such as a card lidder; , Central processing unit 100
A timer 102 that can be programmed by a command from the CPU, an interface 106 that outputs a control signal based on a signal from the central processing unit 100, and an interface 1 for input / output.
The display unit 107 includes a display unit 107 for displaying a district display and input data, and an operation unit 108 for performing an operation input such as a ten-key pad, which is connected via 05.

The operation of the security alarm display device 1 thus configured will be described with reference to the flowchart of FIG. 3 showing an example of a processing program executed by the central processing unit 100.

Normally, the central processing unit 100 collects information from each security sensor 2 via the transmission control device 103. When there is abnormality (intrusion) information from this information, the display unit 107 is operated to display the area where the abnormality has occurred, and an alarm such as intrusion is issued. "Step S01".

On the other hand, a logical expression indicating the interlocking relationship between the controlled device input from the operation unit 108 and the change of the security status of each district is registered in the storage device 101 via the interface 105 and the central processing unit 100. "Steps S02 to S05". Alarm input device 109
When the security state of a certain area is input and set from “Step S07”, a flag indicating the security state of this area is set in the storage device 101 by being taken into the central processing unit 100 via the interface 106. "Step S08". And
The central processing unit 100 determines whether control of the controlled device is necessary based on the newly set flag based on the logical expression registered in the storage device 101. "Step S09". When control is required, the corresponding controlled device 3 via the interface 106
To output a control signal. "Step S10". In this case, when outputting the control signal with a delay time, or when the output time of the control signal is specified, the central processing unit 100 causes the timer 102 to operate, and that the time has elapsed from the timer 102. , A time limit of the control signal is added.

The logical formula input from the numeric keypad is, for example, 1.C1 = T1 × T2 2.C2 = T1 × T2 × T3 3.C3 = T1 × (T2 + T3), etc. 1. is the security area No. 1 (T1) and security A control signal is output to control number 1 (C1) when both area 2 (T2) is in security. 2. In the same way, a control signal is output to control number 2 (C2) when all of security zone 1 (T1), security zone 2 (T2), and security zone 3 (T3) are in a security state. You. In addition, 3. is the security zone No. 1 (T1) and the security zone No. 2 (T1)
A control signal is output to control number 3 (C3) when any one of 2) or 3 (T3) is in a guard state. As described above, this logical expression corresponds to the number of the controlled device and is composed of the conditional expression composed of one or more district numbers. Further, if necessary, a logical symbol such as an operation mode (delay time, pulse output) of the output of the control signal is given, and a logical expression is set and registered.

As described above, the security alarm display device 1 uses the security input means for setting the security status of each district input from the security input device 109 in the storage device 101 and the logical expression indicating the interlocking relation input from the numeric keypad 11. Logical expression setting input means to be registered in the storage device 101, and control signal output means for the central processing unit 100 to output a control signal as necessary from the logical expression registered in the storage device 101 and the input alarm state. In addition, it is possible to control the controlled equipment 3 such as a door lock, a lighting device, an elevator, and various display devices according to the security state of each district. By inputting or rewriting the logical expression in this way, it is possible to easily cope with the situation on site.

[Effects of the Invention] As described above, the disaster prevention alarm device of the present invention is designed to control a controlled device such as a door lock, a lighting device, an elevator, or various display devices based on a security state input for each area. By inputting and registering the logical expression indicating the interlocking relationship from the operation unit, or by rewriting the already registered logical expression, control corresponding to the property can be performed on site,
