Description

[Detailed description of the invention] This invention relates to a security device.

Conventional crime prevention devices are configured to install patrol switches at multiple locations along a patrol route starting from the location where the surveillance panel is installed in one building, and to display to all monitors whether or not the five patrol switches are operated. - When one security guard sequentially operates patrol switches along the patrol route, another guard checks the operation of the patrol switch on the surveillance board, and a specific patrol switch is not operated. It was determined that there was an abnormality in the patrol area just before the location where the patrol switch was installed, and a report was made to the security center.

However, such conventional security devices require two security guards to guard one building.

Therefore, an object of the present invention is to provide a crime prevention device that can reduce the number of viFWg members.

As shown in FIG. 1, the crime prevention device of the present invention includes a patrol start switch 21 and a patrol end switch 22 installed at the patrol start position of a patrol route, and a patrol route divided into patrol sections as many as the total number of collars. Number of views cyclic switch 238~

31 to 23n, the timer means 24B fully opens the clock in response to the operation of the cycle start switch 21;
B, and the cycle switches 231 to 23n of the number of wears are set to B.
In response to each operation, the timer means 24B stops clocking, and sets the timer means 24B to the set time of the cycle section immediately after the operated cycle switch, and responds to the operation of the cycle end switch 22. The control means 25 is configured to stop the time measurement of the timer means 24B, and the alarm 26 is configured to respond to the timer 7 of the timer means. An embodiment of the present invention will be described with reference to FIGS. 2 to 4, in which the number of security guards is reduced by notifying the security personnel. This security device, as shown in Figure 2,
A monitoring panel 1 is installed in a security guard's room of a building, and a plurality of circulation switches 23 to 2n are installed at various locations in the building. In this case, the monitoring panel 1 includes a tour start switch 3, a tour end switch 4, a central processing unit 5, indicator lights 68 to 6n corresponding to each tour section, and an alarm 7. Further, the plurality of cyclic switches 2a to 2n are connected to the monitoring panel 1 via repeaters 83 to 8n, respectively.
A transmission cable 9 is used to perform time-division multiplex transmission between and the repeaters 88 to 8n.

Next, the operation of this security device will be explained in Figures 3 and 4.
This will be explained with reference to the figures.

n, and a time T□ to Tn+, which is sufficient to travel through all of the n+1 cyclic sections D□ to Dn+□ divided by these cyclic switches sw~-JWn, is set.

(2) Operate the patrol start switch 3.

(3) Set N=1 and set the measurement time to zero (set time T1 to the timer).

(4) Start the timer 41.

(5) Determine which cyclic switch SWN has been operated.

(6) When the determination result in step (5) is NO, it is determined whether the time measurement value is within the set time], and when the i1'lJ determination result is YES, the process returns to step (5).

(7) If the determination result in step (6) is NO, stop time measurement.

(8) The indicator light LPN corresponding to the Nth patrol section is made to blink and the alarm 7 is made to sound.

(9) If the determination result in step (5) is YES, stop time measurement.

(10) Turn on the indicator light LP.

(11) Let N=N+1.

(12) Set the measurement time to zero (set the time TN to the timer).

(13) Determine whether or not the cycle end switch 4 has been operated. If the determination result is NO, return to step (4).

(]4) If the determination result in step (]3) is YES, turn off all the indicator lights LP-LPn+□.

In addition, in the above flow, steps (4) and (6
).

In terms of hardware, (7) sets a setting value corresponding to the set time TN in the subtraction counter, subtracts a clock pulse of a constant cycle M from this setting value, and when the count value of the subtraction counter becomes 0. This is realized by generating an output at
Setting values corresponding to l'1 to Tn+□ are sequentially set.

By performing the above flow, after operating the patrol start switch 3, the guard is on patrol (and the patrol switches SW□ to SWn on the patrol route and the patrol end switch 4)
and are operated in sequence before the set time of the immediately preceding patrol section D□-Dn+1 has elapsed, and when the patrol is completed, the indicator lights LP-LPn+J will be turned on in sequence according to the progress of the patrol, and during the tour. For example, if an abnormality occurs in the circuit section D3 and the circuit switch SW cannot be operated within the set time 13, the indicator lights LP2 will light up, the indicator lights LP3 will blink, and the indicator lights LP4 to LPn+1 will light up. is turned off, and the alarm 7 sounds. As a result, it is possible to determine where the abnormality has occurred.

Furthermore, if the patrol end switch 4 is operated during the patrol, the vigilance operation can be interrupted at that time.

As a result of this configuration, it is possible to automatically report any abnormality that occurs during the patrol, and it is not necessary for another security guard to monitor the status of the monitoring board 1 while the - person V security guard is patrolling. The number of security guards can be reduced.

Note that in addition to displaying and warning, it may also be printed out.

Another embodiment of the invention will be described based on FIG. This security device is a hardware implementation of the above-mentioned embodiment, and includes two patrol switches and 7
