2. Description of the Related Art FIG. 6 is an explanatory view of a conventional example. Reference numeral 31 is a monitoring center, 32-1 to 32-n are monitored parts, 33 is a switching network, 34-1 to 34-5 are intrusion sensors, and 35. Is the transmitter,
36 is an entrance / exit gate, 37 is a building, 38 is an entrance door, 39 is a corridor, 40 and 41 are rooms, 42 is a communication control device, 43 is a data processing device, 44 is a display device, and 45 is an operation input unit.

When the start of monitoring is set when the staff member exits, the transmitting unit 35 determines, based on the detection signals of the intrusion sensors 34-1 to 34-5 or the detection signals of other sensors (not shown).
An alarm signal is sent to the monitoring center 31 via the switching network 33. Also, if monitoring cancellation is set when staff members come to the office, an alarm signal is sent to the monitoring center 31 only in the case of a detection signal of a sensor such as a fire sensor that monitors for 24 hours, and the detection signals of other intrusion detection sensors are ignored. It will be.

Various types of intrusion sensors 34-1 to 34-5 are already known, and for example, the entrance / exit gate 3
An intrusion infrared sensor 34-5 in which an infrared light source and an infrared sensor are arranged to face each other is provided at 6, and an entrance magnet sensor that generates a detection signal by opening the entrance door 38 at an entrance door 38 of a building 37. 34-4 is provided. In addition, in the corridor 39 and the rooms 40 and 41, intrusion infrared sensors 34-3, 34-2, which detect infrared rays from the human body,
34-1 and a fire sensor etc. are provided.

In the monitoring center 31, the monitored parts 32-1 to 32-1
The alarm signal from 32-n is received by the communication control device 42, the monitored portion information added to the alarm signal is identified by the data processing device 43, and the alarm signal sending monitored portion is displayed on the display device 44. Based on this, the guard will be contacted, and the guard will be dispatched to the monitored part for transmitting an alarm signal. Therefore, in the monitoring center 31, a plurality of monitored units 32-1
~ 32-n can be remotely monitored.

[0006]

As described above, the monitored portion 32 provided with the plurality of intrusion sensors 34-1 to 34-5.
In -1 to 32-n, it is necessary to provide an operation input unit for setting monitoring start and monitoring cancellation at a position outside the entrance / exit gate 36 where no intrusion sensor is detected. When the operation input unit is provided in the indoor transmission unit 35, for example, the detection signals of the plurality of intrusion sensors 34-1 to 34-5 are added to the transmission unit 35 before the monitoring start is set and the user exits. Then, an alarm signal will be sent from the transmitter 35 to the monitoring center 31, and a plurality of intrusion sensors 34-1 to 34-34 will be provided before entering the room 41 of the transmitter 35 to cancel the monitoring after the start of monitoring. The detection signal of -5 is added to the transmission unit 35, and a problem occurs that an alarm signal is transmitted from the transmission unit 35 to the monitoring center 31.

Therefore, if an operation input unit for setting the start and stop of monitoring is installed outdoors, such as outside the entrance / exit gate 36, it is necessary to provide a structure for protection from wind and rain, and an unspecified number of people. It may be damaged by mischief as it passes. From this point of view, it is necessary to provide the operation input unit inside the monitored units 32-1 to 32-n. In that case, if one intrusion sensor is provided and a detection signal of the intrusion sensor is obtained within a normal time from the start of monitoring to the exit, the transmission unit 35 is instructed to ignore it. The transmitter 35 is set so that the detection signal is ignored even when the monitoring is canceled within a normal time until the monitoring is canceled after the detection signal of the intrusion sensor is obtained. be able to.

Therefore, when the operation input section for starting and canceling the monitoring is provided inside the monitored sections 32-1 to 32-n, it can be dealt with only when one intrusion sensor is provided. It is not possible to deal with the case where a plurality of intrusion sensors are provided. It is an object of the present invention to be able to handle a plurality of intrusion sensors even when an operation input unit for starting and canceling monitoring is provided inside.

[0009]

A remote monitoring system according to the present invention will be described with reference to FIG. 1. The remote monitoring system includes a plurality of monitored units 2-1 to 2-n connected via a switching network 3 to a monitoring center. 1
In the remote monitoring system for monitoring, the monitored units 2-1 to 2-n send a warning signal to the monitoring center 1 based on the detection signals of the sensors 4 installed at a plurality of locations.
And a setting table 6 in which a plurality of sensors 4 along the entry / exit path for setting monitoring start or monitoring in the transmission unit 5 are used as entry / exit sensors, and waiting times are set for the entry / exit sensors. When the start of monitoring is set, the transmitting unit 5 determines that it is normal when the detection signals of a plurality of entry / exit sensors along the entry / exit route are sequentially obtained within the waiting time set in the setting table 6. When the detection signal from the entrance / exit sensor is obtained after the waiting time is exceeded, it is determined that an abnormality has occurred, and when it is determined that this abnormality has occurred, an alarm signal is sent to the monitoring center 1.
Further, after the monitoring is started, the detection signals of the plurality of entrance / exit sensors along the entrance / exit route are sequentially obtained, and when the monitoring is canceled within the waiting time set in the setting table 6, it is determined as normal,
If monitoring is not canceled within the waiting time, it is judged as abnormal,
When it is determined that this is abnormal, an alarm signal is sent to the monitoring center 1.

[0010]

The plurality of intrusion sensors along the entry / exit paths among the various sensors 4 are used as entry / exit sensors, and the waiting time is set in the setting table 6 for the plurality of entry / exit sensors. As a result, for example, in the case where the monitoring start is set in the transmission unit 5 and the user exits, the detection signal of the second entrance / exit sensor along the entrance / exit path is obtained after the detection signal of the first entrance / exit sensor is obtained. Is obtained. When the vehicle normally exits along the entry / exit route, the detection signal of each entry / exit sensor is obtained within a preset waiting time, so the transmitter 5 determines that the entry / exit sensor is normal. In addition, when canceling the monitoring, the detection signals of the entrance / exit sensors along the entrance / exit route are sequentially obtained from the entrance side, but when the canceling operation is performed within the waiting time for each entrance / exit sensor, it is sent. The unit 5 determines that it is normal. An alarm signal is sent to the monitoring center 1 as an abnormal signal except when the detection signal of the entrance / exit sensor is other than the above-mentioned normality judgment. Therefore, even when a plurality of intrusion sensors are arranged, it is possible to provide operation input sections for starting and canceling monitoring inside the monitored sections 2-1 to 2-n.

The operation input unit 22 is used to set monitoring start and monitoring cancellation. For example, a card reader for reading a magnetic card carried by a specific person or a magnetic key can be used for input operation. It can be provided on the side of the housing of the part 15 or inside it.

Further, the setting table 16 is constructed by utilizing a partial area of a random access memory (RAM) or a read only memory (ROM) in the transmission unit 15, or is constructed externally of the transmission unit 15. Can be
In this setting table 16, the sensors along the entry / exit paths among the sensors 14-1 to 14-m are used as entry / exit sensors, and the waiting time is set for the entry / exit sensors.
If the operation input unit 22 is provided with a ten-key pad or the like, this waiting time can be set or changed by using the ten-key pad or the like. Further, in order to avoid abuse, it is possible to set it only by a control command from the monitoring center 11 or by a maintenance person, and it is also possible not to arbitrarily set it on the monitored parts 12-1 to 12-n side.

When the detection signals of the sensors 14-1 to 14-m are applied to the interface section 19, the processor 18
Determines whether it is after the monitoring start setting or after the monitoring cancellation setting, and when the monitoring start setting is performed, determines whether the sensor that generated the detection signal is the entry / exit sensor. This can be easily done by referring to the setting table 16. Then, in the case of the entrance / exit sensor, it is determined whether or not the sensor has occurred within the waiting time set in the setting table 16.

When the detection signal is obtained from the entrance / exit sensor and within the waiting time after the setting of the start of monitoring, it is determined to be normal. Further, if the detection signal is after the waiting time after the start of monitoring is set by the entrance / exit sensor, it is judged as abnormal. If the sensor is not the entry / exit sensor, it is also determined to be abnormal. When it is determined to be abnormal, the line controller 20 is activated to automatically call the monitoring center 11, and the communication control device 2 of the monitoring center 11 is activated.
3 automatically responds to the call from the switching network 13, and when the line control unit 20 of the monitored unit confirms the response of the monitoring center 11, it sends an alarm signal to which the monitored unit information is added.

In the monitoring center 11, the alarm signal received via the communication control device 23 is processed by the data processing device 24, and the presence or absence of the alarm is displayed on the display device 25 for the monitored portion, or the alarm signal is transmitted. Displays the name and address of the monitored part. Based on that, the guards will be contacted.

FIG. 3 is an explanatory view of the monitored portion. In the monitored portion having the building 28 on the site having the entrance / exit gate 29, the transmitting portion 15 is arranged in the building 28 and the transmitting portion 15 is provided.
When the operation input unit for setting the monitoring start and the monitoring cancellation is provided in the, the normal entry / exit route 27 for performing the monitoring start and the monitoring cancellation setting operation is shown by the dotted line. Therefore, when a plurality of intrusion sensors S1 to S7 are arranged, the sensors S1 to S4 along the entry / exit path 27 are used as entry / exit sensors.

Further, after setting the start of monitoring in the transmitting section 15, when the user exits along the entrance / exit path 27, the entrance / exit sensors S1 to S1.
The detection signals of S4 are 10 seconds, 20 seconds, 40 seconds and 6 seconds, respectively.
If it is normal within 0 seconds, the entry / exit sensor S is set as the exit waiting time of the setting table 16 shown in FIG.
1 to 4 corresponding to 1 to S4, 10, 20, 4 respectively
Set 0, 60. In addition, the building 2 along the entrance / exit path 27
When the user goes into 8 to perform the monitoring cancellation operation, the detection signals of the entrance / exit sensors S1 to S4 are 60 seconds, 40 seconds, and 20 seconds, respectively.
If it is normal within 2 seconds and 10 seconds, the waiting time at the office not shown in the setting table 16 of FIG.
6 in the areas corresponding to the entrance / exit sensors S1 to S4, respectively.
Set 0, 40, 20, and 10. Also sensors S5 to S7
Even if it is an intrusion sensor, if it is arranged at a position where a detection signal cannot be obtained when entering / exiting along the entry / exit path 27, it will not be an entry / exit sensor, so the waiting time for that sensor is not set. Further, even if the sensors other than the intrusion sensor such as the fire sensor and the gas leak sensor are arranged along the entry / exit path 27, they do not perform the intrusion detection and therefore are not the entry / exit sensors.

FIG. 4 is a flowchart of monitoring cancellation in the monitoring state according to the embodiment of the present invention. In the monitoring state for monitoring the monitored portion, i = 1 (a1) and whether or not the sensor i is input. (A2), if there is no input from the sensor i, i = i + 1 is set (a10), and it is determined whether i> m (a11). That is, the total number of sensors is m, and the sensor 1
It is determined whether or not the determination process for each sensor from the sensor to the sensor m is completed. If i> m, sensors 1 to m
Since the processing for is ended, the process returns to the start step (a12).

When it is determined that the sensor i is input in step (a2), it is determined whether the sensor i is an entrance / exit sensor (a3). If the sensor is not an entrance / exit sensor, it is determined that an abnormality has been detected by the sensor i, and an abnormality is notified (a9). When it is determined in step (a3) that the sensor is the entrance / exit sensor, the operation of the entry / exit waiting time timer of the sensor i is started (a4). That is, the timer that sets the waiting time corresponding to the entrance / exit sensor is started.

Next, it is judged whether or not the entrance / exit waiting time of the sensor i has timed out (a5). In the case of a time-out, since the waiting time corresponding to the entry / exit timer has passed, it is reported as an abnormality detection by the sensor i (a9). If the timeout has not occurred, it is determined whether or not it is a release operation (a6). If it is not the release operation, the process returns to step (a5). In the case of a release operation, a notification of release of monitoring is sent (a
7), the monitoring cancellation operation is in progress (a8).

Referring to FIGS. 2 and 3, when the entrance / exit gate 29 is passed through while the monitored part is being monitored, the entrance / exit sensor S4 is detected.
Is input to the interface unit 19. As a result, it is determined in step (a2) that there is a sensor input, in step (a3) it is determined that the sensor is an entrance / exit sensor, and in step (a4), the timer for the entrance / exit waiting time corresponding to the entrance / exit sensor S4 is started. It That is, the waiting time of 60 seconds set for the entry / exit sensor S4 is read from the setting table 16, and the timer set to 60 seconds is started.

Further, during that time, when entering the building 28, the detection signal of the entrance / exit sensor S3 is input to the interface section 19. Then, steps (a2), (a3), (a4)
Thus, 40 seconds of the entry / exit waiting time corresponding to the entry / exit sensor S3 is read from the setting table 16, and the timer set to 40 seconds is started. Similarly, the entrance / exit sensor S
The detection signals of S2 and S1 are input to the interface unit 19, and the entry and exit waiting times of 20 seconds and 10 seconds corresponding to the entry and exit sensors S2 and S1 from the setting table 16 are set in the timer and activated.

Then, in step (a5), it is determined whether or not the timers corresponding to the entrance / exit sensors S1 to S4 have timed out, and if any timer is released before the time-out, the release operation is normally performed. If it has been performed, a cancellation notification is given in step (a7), and the monitoring is being canceled (a8).

In the case of an intruder, since the release operation is not performed, the time-out occurs in step (a5), and an abnormality notification is made by the entry / exit sensor corresponding to the timer that timed out first.

FIG. 5 is a flow chart of the monitoring start in the monitoring release state according to the embodiment of the present invention. It is judged whether or not the monitoring operation is performed (b1), and the operation to start the monitoring in the monitoring release state. Immediately after that, a monitoring start notification is issued (b2). Then, i = 1 is set (b3), and it is determined whether or not the sensor i is an entrance / exit sensor (b4).

If the sensor i is not an entry / exit sensor, it is determined whether or not there is an input from the sensor i (b13). If there is no input, then i = i + 1 (b15), and the result is i>
It is determined whether or not m (b16), and if i> m, the process proceeds to step (b4). If i> m, it means that the determination process has been completed for m sensors, and thus the monitoring operation state is set (b17).

If it is determined in step (b13) that the sensor i has been input, it means that an abnormality has been detected by a sensor other than the entry / exit sensor. Therefore, an abnormality is reported by the sensor i (b14). Then, the step (b
Go to 15).

If it is determined in step (b4) that the sensor i is an entrance / exit sensor, the operation of the entrance / exit waiting time timer corresponding to the sensor i is started as the exit waiting time (b5), and the timer times out. It is determined whether or not (b6). Then, in the case of time-out, that is, after the exit waiting time has elapsed, it is determined whether or not there is an input from the sensor i (b7), and the process proceeds to step (b15). And
When the processing for the m sensors is completed in step (b16), it corresponds to the case where the monitoring start operation is performed and then the user exits within the exit waiting time, and the monitoring operation state is normally entered. .

If it is determined in step (b7) that the sensor i has been input, the exit waiting time after the operation for starting the monitoring has already elapsed, and the entry / exit sensor has already detected. Since the release operation may be performed in such a state, the operation of the entry / exit waiting time timer corresponding to the sensor i is started as the release waiting time (b8). Then, due to the timeout of the timer (b9), the release operation is not performed even after the release waiting time elapses. Therefore, it is determined that the sensor i has detected an abnormality, and an abnormality is notified (b1).
4). Before the timeout, it is judged whether or not the release operation is performed (b10). If the release operation is not performed, the process proceeds to step (b9). If the release operation is performed, the release operation is performed within the release waiting time. This is the case when the operation is performed, and it is determined that the operation is normal, and a cancellation notification is issued (b11).

Referring to FIGS. 2 and 3, by performing a monitoring start operation (b1), the monitoring center is notified of the monitoring start (b2). Then, when exiting along the entrance / exit path 27, the detection signal of the entrance / exit sensor S1 is input to the interface unit 19. This entry / exit sensor S1
In step (b4), the sensor is determined to be an entrance / exit sensor, the waiting time of 60 seconds of the entrance / exit sensor S1 at the time of exit is read from the setting table 16, and the timer in which this waiting time is set is started (b5). . Similarly, the sensors S1 to S
It is determined whether the sensor is an entrance / exit sensor for No. 7, and for each of the entrance / exit sensors, a timer in which an exit waiting time is set is started.

Then, it is judged whether or not there is an input from the entrance / exit sensors S1 to S4 by the timeout of the timer corresponding to the entrance / exit sensors S1 to S4 (b7), and the exit corresponding to the exit waiting time by the timer corresponding to the entrance / exit sensors S1 to S4. If you do
At each timeout, there is no sensor input. Therefore, through steps (b15) and (b16),
The monitor operation state is set (b17).

Further, after the operation for starting the monitoring is performed, the operation for canceling the monitoring may be performed in order to return to the monitoring canceled state of the previous state. In that case, since there is an input from the entrance / exit sensor after the exit waiting time has elapsed, it is determined in step (b8) that the sensor i has been input, and step (b1)
When it is determined that the release operation is performed in 0), it is determined that the monitor release is normally performed, and the monitor release notification is sent to the monitor Santa (b12).
