[Operation of intruder repelling system]
Next, with reference to FIG. 4 and FIG. 5, operation | movement of the intruder repelling system concerning this Embodiment is demonstrated. FIG. 4 is a flowchart showing the monitoring operation of the intruder repelling system according to this embodiment. FIG. 5 is a signal waveform diagram showing the monitoring operation of the intruder repelling system according to this embodiment.

  At this time, N1 indicating the smallest number of pulses corresponding to the alarm level 1 is set in advance as an alarm determination value in the storage unit 14, and N2 indicating the number of pulses greater than N1 corresponding to the alarm level 2 is set. It is assumed that the largest number of pulses N3 (N1 <N2 <N3) is set corresponding to the alarm level 3. As a result, the number of pulses confirmed at the time of determining each alarm level increases in the order of alarm level 1, alarm level 2, and alarm level 3, and the determination accuracy increases accordingly.

When the start of the monitoring operation is instructed by an operation from the operation input unit 13 or the remote controller 4, the control unit 17 of the control device 1 starts the intrusion monitoring process shown in FIG.
First, the pulse counting means 17B initializes the counter value to zero (step 100), and waits for the sensor output by the pulse signal from the pulse generator 11 (step 101). Here, when a pulse signal is output from the pulse generator 11 in response to the detection signal from the sensor 2A or the switch 2B and the input of the sensor output is confirmed (step 101: YES), the timer 17A is activated and counted. The timing of the period (TUP) is started (step 102 / time t0 in FIG. 5), and the counter value is incremented by 1 (step 103).

Then, the alarm determination unit 17C compares the counter value with the alarm determination value N1 of the alarm level 1 preset in the storage unit 14, and when the counter value does not reach N1 (step 104: NO), the timer It is determined whether 17A has timed up.
If the time is not up (step 105: NO), the sensor output is confirmed by the pulse counting means 17B. If there is no sensor output (step 106: NO), the process returns to step 105. If there is a sensor output (step 106: YES), the process returns to step 103 to add the counter value. Further, when the timer 17A has timed up and the counting period has ended (step 105: YES), the number of pulses for which an alarm should be output within the counting period could not be counted. Prepare for the counting period.

On the other hand, when the counter value reaches N1 (step 104: YES / time t1 in FIG. 5), the number of pulses for which alarm level 1 should be output within the counting period is counted.
Therefore, the alarm determination unit 17C determines that the output of the alarm level 1 is necessary, and instructs the alarm display device 31 corresponding to the alarm level 1 of the alarm device 3 to output the alarm level 1 (step 110). ). Thereby, in the alarm display device 31, first, as the alarm level 1 that has the least influence on the surroundings, the rotating lamp is driven to warn the detection of the intruder by visual display.

Next, the pulse counting unit 17B outputs a pulse signal from the pulse generator 11 in response to a new detection signal from the sensor 2A or the switch 2B, and confirms the input of the sensor output (step 115: YES). The counter value is incremented by 1 (step 116).
Then, the alarm determination unit 17C compares the counter value with the alarm determination value N2 of the alarm level 2 preset in the storage unit 14, and when the counter value does not reach N2 (step 117: NO), the alarm determination unit 17C Since the number of pulses to be output has not been reached, the process returns to step 115 to wait for a new sensor output.

On the other hand, when the counter value reaches N2 (step 117: YES / time t2 in FIG. 5), the number of pulses for which the alarm level 2 should be output within the counting period is counted.
Therefore, the alarm determination unit 17C determines that the output of the alarm level 2 is necessary, and instructs the alarm ringing device 32 corresponding to the alarm level 2 of the alarm device 3 to output the alarm level 2 (step 120). ). As a result, the alarm sounding device 32 sounds the alarm buzzer as an alarm level 2 having the next largest influence on the surroundings, and warns the detection of the intruder by an audible display.

Next, the pulse counting unit 17B outputs a pulse signal from the pulse generator 11 in response to a new detection signal from the sensor 2A or the switch 2B, and confirms the input of the sensor output (step 125: YES). The counter value is incremented by 1 (step 126).
Then, the alarm determination unit 17C compares the counter value with the alarm determination value N3 of the alarm level 3 preset in the storage unit 14, and if the counter value has not reached N3 (step 127: NO), the alarm determination unit 17C Since the number of pulses to be output has not been reached, the process returns to step 125 to wait for sensor output.

On the other hand, when the counter value reaches N3 (step 127: YES / time t3 in FIG. 5), the number of pulses for which the alarm level 3 should be output within the counting period is counted.
Therefore, the alarm determination unit 17C determines that the output of the alarm level 3 is necessary, and instructs the crime prevention spray injection apparatus 33 corresponding to the alarm level 3 of the alarm device 3 to output the alarm level 3 (step S1). 130). Thereby, in the crime prevention spray injection apparatus 33, sprays, such as OC gas mentioned above, are injected with respect to an intruder as the alarm level 3 with the largest influence on the circumference | surroundings.

At this time, the alarm output of each alarm level is stopped individually or collectively by the alarm determination unit 17C according to the operation from the operation input unit 13. Therefore, if it is confirmed that the alarm is false before reaching the final alarm level 3, the alarm output may be stopped.
For stopping the alarm output, a predetermined operation may be performed from the operation input unit 13 or the switch 13A (see FIG. 2), or a predetermined signal may be transmitted to the control device 1 by performing a predetermined operation with the remote controller 4.

As described above, in the present embodiment, the pulse signal corresponding to the detection signal from the sensor is counted by the pulse counting means 17B, and the number of pulses counted within the predetermined counting period and each of the number stored in the storage unit 14 are stored. Since the alarm determination values 171C are compared with the alarm determination values N1 to N3 of the alarm level and the alarm determination means 17C determines whether the alarm output is necessary or not at each alarm level, the detection outputs from the sensors have different determination accuracy. It is possible to determine which one of the alarm levels corresponds to, and to output an alarm corresponding to the alarm level step by step.
As a result, intruders can be surely repelled with multiple levels of alarms, and even if it is erroneously determined that an alarm is required, repelling measures such as spray injection are not immediately performed according to the determination, and the facility user And the influence on the surroundings including those in the facilities can be suppressed. Therefore, it is optimal for a crime prevention system with enhanced repelling measures against intruders in order to protect assets from sophisticated crimes.

Note that the number of alarm levels is not limited to three, but may be two or more. Further, for the alarm determination values N1 to N3, it is sufficient that N1 <N2 <N3 is established, and by adjusting the interval, the time interval until the transition to the next alarm level can be arbitrarily set.
Moreover, although the above description demonstrated as an example using any one sensor as sensor 2A, it is not limited to this. For example, when a plurality of sensors are installed in parallel, a pulse signal based on a detection signal from each sensor may be counted for each sensor, or the pulse signals of all the sensors may be added up and counted. In addition, when the count value is obtained for each sensor, the necessity of alarm output is individually determined based on the alarm judgment value with these count values, and the necessity of alarm output is determined by the logical sum or logical product of these judgments. May be comprehensively determined. The same applies to the switch 2B.

[Second Embodiment]
Next, with reference to FIG. 6 and FIG. 7, an intruder repelling system according to a second embodiment of the present invention will be described. FIG. 6 is a flowchart showing the monitoring operation of the intruder repelling system according to this embodiment. FIG. 7 is a signal waveform diagram showing the monitoring operation of the intruder repelling system according to this embodiment.
In the present embodiment, in the first embodiment described above, the alarm output being output is automatically stopped in response to the stop of the timing operation of the timer 17A. The configuration of the intruder repelling system according to the present embodiment is the same as that of the first embodiment (see FIG. 1), and the description thereof is omitted here.

When instructed to start a monitoring operation by an operation from the operation input unit 13 or the remote controller 4, the control unit 17 of the control device 1 starts the intrusion monitoring process shown in FIG. In FIG. 6, the same or equivalent steps as those in FIG. 4 described above are denoted by the same reference numerals.
First, the processing of steps 100 to 106 described above is performed, and when the counter value reaches N1 (step 104: YES / time t1 in FIG. 7), a pulse to output alarm level 1 within the counting period (TUP). The number is counted.

  Therefore, the alarm determination unit 17C determines that the output of the alarm level 1 is necessary, and instructs the alarm display device 31 corresponding to the alarm level 1 of the alarm device 3 to output the alarm level 1 (step 110). ). As a result, the alarm display device 31 drives the rotating lamp to warn the detection of the intruder by visual display.

Thereafter, when the timer 17A continues to count and the counting period has not ended (step 111: NO), the pulse counting means 17B receives a new signal from the sensor 2A or the switch 2B in steps 111, 115 to 117. The pulse signal corresponding to the detection signal is counted.
On the other hand, when the time counting operation of timer 17A is stopped and the counting period (TUP) ends (step 111: YES / time t11 in FIG. 7), alarm determination means 17C determines that the output of alarm level 1 is unnecessary. Then, the alarm display device 31 corresponding to the alarm level 1 in the alarm device 3 is instructed to stop the output of the alarm level 1 (step 112), and the process returns to step 100. Thereby, in the alarm display device 31, the driving of the rotating lamp is stopped and the alarm output is stopped.

In addition, when the above-described processing of steps 111, 115 to 117 is performed and the counter value reaches N2 (step 117: YES), the number of pulses that should output alarm level 2 within the counting period is counted. Become.
Therefore, the alarm determination unit 17C determines that the output of the alarm level 2 is necessary, and instructs the alarm ringing device 32 corresponding to the alarm level 2 of the alarm device 3 to output the alarm level 2 (step 120). ). Accordingly, the alarm sounding device 32 sounds an alarm buzzer to warn the detection of the intruder by an audible display.

Thereafter, when the timer 17A continues to count and the counting period has not expired (step 121: NO), the pulse counting means 17B receives a new signal from the sensor 2A or the switch 2B in steps 121, 125 to 127. The pulse signal corresponding to the detection signal is counted.
On the other hand, when the counting operation of the timer 17A is stopped and the counting period TUP ends (step 121: YES), the alarm determination unit 17C determines that the output of the alarm level 2 is unnecessary, and the alarm device 3 The alarm ringing device 32 corresponding to the alarm level 2 is instructed to stop the output of the alarm level 2, and the alarm display device 31 corresponding to the alarm level 1 is instructed to stop the output of the alarm level 1 (step 122). Return to step 100. Thereby, in the alarm sounding device 32, the sounding of the alarm buzzer is stopped and the alarm output is stopped.

In addition, when the processing of steps 121, 125 to 127 described above is performed and the counter value reaches N3 (step 127: YES), the number of pulses for which alarm level 3 should be output within the counting period is counted. Become.
Therefore, the alarm determination unit 17C determines that the output of the alarm level 3 is necessary, and instructs the crime prevention spray injection apparatus 33 corresponding to the alarm level 3 of the alarm device 3 to output the alarm level 3 (step S1). 130). Thereby, in the crime prevention spray injection apparatus 33, sprays, such as OC gas mentioned above, are injected with respect to an intruder.

  As described above, in the present embodiment, the alarm being output is stopped at the end of the counting period, so that an erroneous detection signal is temporarily output from the sensor or a pseudo detection signal is input.
