BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security switching device, and in particular, sets a plurality of security areas in a building to be security and switches between security start and security end in each security area. And when the security ending operation by the security switching means of the second security area is performed within a predetermined time after the security ending operation by the security switching means of the first security area, The present invention relates to a security switching device that terminates security.

[0002]

2. Description of the Related Art Conventionally, buildings where security is desired, such as offices and banks (hereinafter referred to as security target areas in this specification).
A security switching device for performing a security start / security end switching operation has been proposed.

The security switching device is roughly classified into a case where the security switching means constituting the security switching device is installed outside the security target area and a case where the security switching means is installed inside the security target area.

[0004] When the security switching means is installed outside the security target area, when security start / end operations are performed, security of all the security target areas starts and ends at the same time.

[0005] However, if the security switching means is installed in the security target area and security is started simultaneously with the security start operation, an alarm is output even though the operator is still in the security target area. Things happen. Also, at the end of security, due to the security switching means being installed in the area to be guarded, in order to perform the operation of ending security, the operation of ending security must be performed unless entering the area to be guarded during security. Since it is not possible to do so, the sensor detects the operator and outputs an alarm signal when the operator enters the security target area to end the security.

Therefore, in order to avoid these inconveniences,
At the time of security start, even if the security start operation is performed, the time necessary for the operator to leave the security target area after the security start operation is set in a timer in advance, and during the time counting by this timer, the sensor is activated. It does not output an alarm signal even when an operator is detected. Also, at the time of the security end operation, the time required for the operator to enter the security target area, perform the security end operation, and end the security is set in the timer in advance, and during the time counting by this timer, If the intrusion signal is held without being output as an alarm and the intrusion signal is detected, timing by the timer is started and if the security end operation is performed during the time measurement, the security of all areas subject to security will be terminated and the intrusion signal Is resetting.

[0007]

[Problem to be Solved by the Invention] However, even in the case where the security switching means is installed in the security target area, the last exiting person performs security start operation by the security switching means and starts security in the security target area. Immediately after that, if another person (for example, a robber) threatens and forcibly performs a correct security end operation, there is a problem that the security of all the areas to be guarded ends and the security area cannot be protected from robbery. Was.

[0008] Accordingly, an object of the present invention is to provide a first security target area having an entrance to the outside and a second security target area which can be entered only from the first security target area. The security of the second security target area ends only when the security end operation by the security switching means of the second security target area is performed within a predetermined time after the security end operation by the security switching means of the one security target area, It is an object of the present invention to provide a security switching device capable of reliably protecting a security target area and building a reliable security target area.

Another object of the present invention is to provide security in a security target area divided into a first security target area having an entrance to the outside and a second security target area which can be entered only from the first security target area. When starting, by performing the security operation in either the first security switching means or the second security switching means, it is possible to start the security of all the security target areas, and to guard the security area An object of the present invention is to provide a security switching device that can save time and effort for operation when starting and can surely start security in all security target areas.

When the first sensor group 17 and the second sensor group 18 detect an abnormality, an abnormality detection signal of the security target area is output to the control unit 15.

Among them, the first security switching means 11
Is installed outside the first security target area in order to perform a switching operation between security start and security end of the first security target area 13 having an entrance to / from the outside.

The second security switching means 12 performs a first security operation for switching between a security start and a security end of a second security object area 14 which can enter through the first security object area 13. It is installed in the target area 13. in this way,
The security target area is divided into a first security target area 13 and a second security target area 14.

The control means 15 receives signals from the first security switching means 11 and the second security switching means 12 and controls the first security area 13 and the second security area 1.
Signal control such as switching of security of 4 and transmission of an abnormal signal to the centralized monitoring center 16 is performed. A central processing unit 51 that outputs a command signal to switch security in a security target area based on signal inputs from the first security switching means 11 and the second security switching means 12; The first timer means 53a measures the time from when the security start operation is performed by the second security change means 12 until the security starts, and the time is measured after the security end operation is performed by the first security change means 11. Whether to transmit detection signals from the first sensor group 17 and the second sensor group 18 to the centralized monitoring center 16 of the security company based on a command from the second timer means 53b and the central processing unit 51 to start. Transmission control unit 54 that performs determination control
Is provided. Reference numeral 52 denotes an interface.

Then, only when the security end operation by the second security change means 12 is performed within a predetermined time after the security end operation by the first security change means 11, the security of the second security target area 14 is not changed. finish.

Thus, when the security end operation is performed by the first security switching means 11 and a security end signal is output, the security of the first security target area 13 is ended and the second timer means 53b is provided. Starts the timekeeping, and when the security end operation is performed by the second security switching means 12 during the timekeeping, the security of the second security target area 14 ends, and the second timer means 53b stops the timekeeping. If the security end operation by the second security switching means 12 is not performed, the switching operation by the second security switching means 12 is prohibited thereafter. Further, in order to enable the security end operation by the second security switching means 12, the security of the first security target area 13 is started by the first security switching means 11 once. Then, the security switching operation by the second security switching means 12 becomes possible. Therefore, the first security switching means 11 again
When the security end operation is performed, the timer starts counting time,
During the counting of the timer, the security end operation by the second security switching means 12 becomes possible.

Next, the operations of the security switching device 1 at the time of starting security and at the time of ending security will be described with reference to the flowcharts shown in FIGS.

(At Security Start) First, the operation at the time of security start will be described. Now, when the last exiting person leaves the security target area such as an office or a financial institution, the first security switching means 11 is operated to perform a security start operation (S-1). 15 and security of all areas subject to security starts immediately (S-
2).

Here, when an abnormality detection signal is output from the first sensor group 17 and the second sensor group 18 to the control means 15, the central processing unit 51
The abnormality detection signal is input to the. Then, a command signal is output from the central processing unit 51 to the transmission control unit 54, and the transmission control unit 5
4 transmits the abnormality detection signals from the sensor groups 17 and 18 to the centralized monitoring center 16 as alarm signals.

Further, the last exited person is the second security switching means 1
In the case where the security start operation is performed using the security control 2 (S-3), when the security start signal is input to the control means 15, the security start signal is input to the central processing unit 51 through the interface 52, and the second security object is input. Only the security of the area 14, that is, the second sensor group 18 is set to the security state (S- 4), and only the abnormality detection signal from the second sensor group 18 is transmitted to the centralized monitoring center 16 through the transmission control unit 54. Second security switching means 12
At the same time as performing the security start operation, the first security target area 1
The first timer means 53a, in which the time required to leave 3 is set, starts measuring time (S-5). During the time counting by the first timer means 53a, no signal is transmitted to the centralized monitoring center 16 even if an intrusion is detected in the first security target area 13. When the time measurement by the first timer means 53a ends, security of the first security target area 13 is started (S-6). As a result, the entire area to be guarded is in the guard state, and the abnormal signal of the first area 13 to be guarded is also transmitted to the centralized monitoring center 16.

(End of Security) Next, the operation at the end of security will be described. When the security is to be ended, a security end operation is performed by the first security switching means 11 (S-11), and a security end signal is sent to the control means 15.
Enter Simultaneously with this security ending operation, only the security of the first security target area 13 ends (S-12), and even if an abnormal signal is detected from the first sensor group 17, the control unit 15
In, control is performed so that the detected abnormal signal is not transmitted from the central processing unit 51 to the transmission control unit 54, and the abnormal signal is not transmitted to the centralized monitoring center 16.

When a security end signal is input from the first security switching means 11 to the control means 15, a security end operation is performed by the first security switching means 11, and then a security end operation of the second security switching means 12 is performed. The second timer means 53b, which has set the time required for completion, starts measuring time (S-1).
3). If the security end operation is performed by the second security switching means 12 while the second timer means 53b is counting (S-1).
4) A security end signal is input to the central processing unit 51 through the interface 52. Then, the second security target area 1
The security of 4 is also completed, the security of all the security target areas is completed (S-15), and the control unit 15 sends a detection signal regarding intrusion by the first sensor group 17 and the second sensor group 18 to the centralized monitoring center. 16 so as not to be transmitted.

If the security end signal is not input from the second security switching means 12 to the control means 15 by the end of the time measurement by the second timer 53b (S-16), the second security is performed simultaneously with the end of the time measurement. The security end operation by the switching means 12 is prohibited (S-17).

After that, in order to be able to perform the security end operation again by the second security switching means 12, once out of the security target area, the first security switching means 11 sets the first security target area 13. An operation to start security is performed (S-1).
8) The security of the first security target area 13 is started (S-).
19). Then, the security switching operation by the second security switching means 12 becomes possible (S-20).

The security switching means may be a numeric keypad device, a card reader device, a security switching device using a key, or the like.

[0029]

[Effects of the Invention] The present invention is configured as described above, and the present invention has the following effects. When the security of the building to be guarded is to be ended, only the first security target area is switched to the security end state by the first security switching means attached near the entrance (passage) of the building, and thereafter within a predetermined time. Only when the second security switching means installed in the first security target area is operated does the security state of the second security target area switch to the security end state, so that, for example, a thief (robber) threatens the security. Even if the end operation is forced, the security end operation is performed by the first security switching means, and only the security in the first security target area is ended, so that the thief thinks that the security in all the security target areas has ended. Therefore, the security target area can be reliably protected, and an extremely reliable security area can be constructed. When starting the security of the security target area, the security of all the security target areas can be started by performing the security start operation in either the first security switching means or the second security switching means. Therefore, it is possible to save the trouble of operation when starting security in the security target area, and it is possible to reliably start security in all security target areas.
