Abstract

PROBLEM TO BE SOLVED: To discriminate whether an invader at night is a person in association with a bank or not, for example, to output an alarm only in the case of the invader other than the relative person and to arranged a sensor so that persons other than the relative person can not notice it. SOLUTION: Corresponding to plural pressure sensors 1 arranged in a monitoring area, an order describing part 3 describes an order table 6 (a table describing the order for the pressure sensors 1 to detect the relative person backward to a monitoring object when the relative person enters the monitoring area of the pressure sensors 1) to be recognized by the relative person. Besides, the detection order of pressure sensors 1 described in the order table 6 is compared with the order of the real detection of the pressure sensors 1 and when they are different from each other, a discrimination part 4 outputs abnormal information to an output part 16. The output part 16, to which the abnormal information in inputted, outputs the warning to the outside. Thus, the alarm can be outputted only in the case of the invader other than the relative person and erroneous alarm is hardly outputted.

2. Description of the Related Art FIG.
FIG. 1 is a configuration diagram of a conventional intrusion monitoring device shown in
In the figure, 11 is a plurality of sensors, 12 is a sensor signal input unit, 13 is a memory unit, 14 is a comparison unit, 15 is a determination unit,
Reference numeral 16 denotes an output unit, 17 denotes a camera control unit, 18 denotes a plurality of cameras, 19 denotes a setting unit, and 20 denotes a control unit. FIG. 6 is an explanatory diagram of an operation when the conventional intrusion monitoring device is installed in, for example, an automatic teller machine corner of a bank.
Is an arrangement diagram, and FIG. 6B is an explanatory diagram showing an example of an intrusion monitoring operation. In the figure, 21 is an automatic teller machine corner of a bank, 22 is an entrance, 23 is an automatic teller machine, and 24 is a first automatic teller machine.
The door, 25 is a second door, and 26 is a bank office. Also,
In the arrangement diagram of FIG. 6A, it is assumed that the sensors 11 are arranged at five positions (1) to (5).

[0005] The sensor 11 used in FIG. 5 is constituted by, for example, arranging a matrix of pyroelectric infrared sensor elements which output signals in response to heat of a human body in front, and providing a convex lens in front thereof. However, the number of sensor elements that react according to the number of people increases or decreases. The sensor 11 is disposed, for example, on the ceiling of an automatic teller machine corner 21 and detects an intruder.

Next, the operation of the conventional intrusion monitoring device will be described. The sensors 11 arranged in each of the above-described areas monitor the set area of the above-mentioned area, and output a sensor signal to the sensor signal input section 12 when detecting an intruder (not shown). The sensor signal input unit 12 outputs the input sensor signal to the control unit 20. Further, the memory unit 13 includes the control unit 2
0 records the input sensor signal. Also, the comparison unit 14
Each time a sensor signal is input to the control unit 20, the difference between the sensor signal and the sensor signal recorded in the memory unit 13 is compared, and the difference information is output to the determination unit 15.

[0005] The determination unit 15 determines the movement of the intruder based on the difference information input from the comparison unit 14, and outputs the determination result to the control unit 20. The control unit 20 outputs the monitoring result to the output unit 16 and the camera control information for controlling the camera 18 to the camera control unit 17 based on the determination result from the determination unit 15. The setting unit 19 sets the timing for recording a sensor signal in the memory 13 and the like.

Next, the specific operation of the intrusion monitor will be described with reference to FIG.
Will be described. For example, if an intruder (not shown)
It is assumed that the user has traveled to the area via the body of FIG.
In this case, the control unit 20 determines that the intruder has entered to use the automatic teller machine 23, and determines that there is no abnormality.
Is output. However, when the intruder has advanced to the area beyond the first door 24, the control unit 20 outputs “alert”. In addition, the control unit 20 outputs “alert release” when the intruder returns to thereafter, and outputs “abnormal” when the intruder further proceeds. When the control unit 20 determines that the state is “abnormal”, the control unit 20 outputs a camera control signal to the camera control unit 17 to direct the camera 18 toward the intruder.

Thus, the conventional intrusion monitoring device detects an abnormality based on the direction of the intruder invading, so that appropriate intrusion monitoring with less false alarm can be performed.

[0008]

The conventional intrusion monitoring device is configured as described above, and has the following problems. (1) A conventional intrusion monitoring device is, for example, an automatic teller machine 2
Reference numeral 3 denotes an intrusion monitoring device that assumes that a bank official is in the office 26 during operation. In other words, this intrusion monitoring device allows the intruder to pass through the automatic teller machine 23 when there is no bank related person in the office 26 at night or the like.
"No abnormalities" even after going back after mischief
Will be output. In other words, there is a problem that this intrusion monitoring device cannot play the role of intrusion monitoring when there is no bank related person in the office 26, such as at night.

(2) As a method for solving the problem (1), when there is no related person in the office 26 at night or the like, when any of the sensors 11 to detects an intruder, Switching may be performed so that all are output as “abnormal”.
However, in the case of switching as described above, a person related to the bank (for example, a collector / delivery person) collects money or the like to make the automatic teller machine 2 available.
There is a problem that an alarm of “abnormal” is output even when the vehicle enters the direction 3.

(3) A conventional intrusion monitoring device uses a pyroelectric infrared sensor mounted on a ceiling or the like to detect an intruder. This pyroelectric infrared sensor cannot be detected if there is an obstacle between the intruder and the intruder. Therefore, it is necessary to dispose the pyroelectric infrared sensor at a position visible from the intruder. For this reason, there has been a problem that an intruder enters the device without being detected by the sensor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. A first object of the present invention is to determine whether a nighttime intruder is, for example, a bank related person, and It is intended to provide an intrusion monitoring device capable of outputting an alarm only to an intruder.

Also,
On the pressure sensor 1, a carpet 10 covering the pressure sensor 1
Is provided. Thereby, the position of the pressure sensor 1 does not need to be noticed by anyone other than the person concerned. Also, here, the route 9 to be taken by the concerned person is represented by “B8” to “B7” to “C7” to “D7” to “D6” to
"D5"-"D4"-"E4"-"E5"-"E6"-
Defined as "E7" to "E8" to "D8" to "C8" to "B8".

Next, the operation of the intrusion monitor will be described. Here, it is assumed that the relevant person has grasped the route 9 shown in FIG. The control unit 2 controls the operation of the entire intrusion monitoring device. In addition, the order entry unit 3 describes the order table 6 shown in FIG. 3 along the route 9 to be taken by the person concerned. Further, when detecting the intruder, the pressure sensor 1 outputs a detection signal to the determination unit 4. The determining unit 4 determines whether or not the intruder in the room is a related person by referring to the order table 6 according to the operation flowchart shown in FIG. 16 is output.

The discriminator 4 starts the timer 5 based on the operation flowchart shown in FIG. Also, the discriminating unit 4
The timer 5 activated by the timer outputs time-out information based on the timer value set by the determination unit 4 to the determination unit 4. The output unit 16 outputs an alarm to the outside (not shown) based on the abnormality information output by the determination unit 4.

If not, the process proceeds to S3. Also, the determination unit 4
In S9, the abnormality information is output to the output unit 16, and the process proceeds to S1.

With the above operation, the intrusion monitoring device of the present invention can perform the following monitoring operation. (1) According to the order table 6 shown in FIG. 3, when a related person invades, the sensor 1 arranged at “B8” of the entrance 7 is to detect first. That is, "B
If the sensor 1 disposed at a position other than “8” detects an intruder for the first time, the intruder is regarded as an intruder other than the relevant person and an alarm is output. (2) According to the order table 6 shown in FIG.
Timer value 2 for "D5" or "E4" to "B8"
0 is all described as 2 seconds. In other words, if the intruder takes 2 seconds or more to move to the adjacent monitoring area 62 from “B8” to “D5”, for example, the intruder is regarded as an intruder other than a related person and outputs an alarm.

(3) According to the order table 6 shown in FIG. 3, since the timer value 63 in the monitoring area 62 of "D4" is not described, the timer 5 is not set in S6.
Therefore, no timeout interrupt occurs in the subsequent reception waiting state (S3). This is because it is assumed that a related person works on the monitoring target 8 such as collecting money in the monitoring area “D4”. That is, the timer value 63
No alarm is output even if the related person stays on the monitoring area 62 where the setting is not made. (4) For example, when a related person is approaching or moving away from the monitoring target 8 along the route 9 and another intruder has entered the room, it is regarded as an intruder other than the related person and an alarm is issued. Output.

As a result, the intrusion monitoring device according to the present invention can determine whether or not an intruder who has entered the room shown in FIG. 3 is a related person, and can output an alarm only to an intruder other than the related person. Therefore, false information can be prevented. Also,
If the order description unit 3 updates the order table 6 every predetermined period, the chances of an intruder other than the involved person being informed of the route 9 are reduced, so that the reliability is improved. In addition, the order entry section 3
If a plurality of order tables 6 are described and the discriminating unit 4 selects and uses the plurality of order tables 6, the order description unit 3 does not need to update the order table 6 every predetermined period. , It will be easier to operate.

Further, in FIG. 2, the carpet 10 is used as the covering of the pressure sensor 1, but other materials may be used. Further, instead of the carpet 10, for example, a grid-like mat that allows a person concerned to determine the monitoring area 62 may be used. In this way, since the concerned person can surely move along the route 9, false alarms are further reduced.
Although the pressure sensors 1 are arranged in a matrix in FIG. 2 for simplicity of explanation, they may be arranged in another shape.

The operation flowchart of the discriminating section 4 shown in FIG. 4 is merely an example, and the above operation flowchart can be variously changed according to the situation when this intrusion monitoring device is commercialized. Further, in this embodiment, the case where the intrusion monitoring device is arranged in the bank has been described as an example, but it goes without saying that the intrusion monitoring device may be arranged in another place where it is determined whether or not the person concerned is involved.
