Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for detecting a person who illegally enters a restricted area such as a specified place or room.

For example, in banking operations, in order to save labor in administrative processing, automatic processing machines such as automatic teller machines, automatic currency exchange machines, and automatic deposit machines are installed in specific rooms, and systems are used to automatically process transactions without staff. However, in this system,
Since there is no staff in charge, it is easy for fraud to occur by intruding into this particular room from the outside.

Therefore, an object of the present invention is to provide an intruder detection device that can reliably detect a person who illegally intrudes into a restricted area such as the above-mentioned specific room.

According to the intruder detection device of the present invention, the first detection means detects that a legitimate person has entered the restricted area, and the second detection means detects the presence of a person in the restricted area. , storage means for storing that there is no person in the restricted area based on the output of the second detection means and erasing the memory based on the output of the first detection means, When you remember that there is no one in the
The intruder detection means emits an intruder detection signal in response to the detection means detecting the presence of a person within the restricted area.
This signal indicates an unauthorized intruder, such as a person who has broken in by breaking the door of a public bath, or a person who has broken in by breaking the surrounding wall, and therefore the unauthorized intruder can be reliably detected. This makes it possible to prevent fraudulent activities in restricted areas.

Note that the above-mentioned setting and resetting of the memory device do not indicate the presence or absence of a signal (they indicate two different operating states of the memory device).

An embodiment of the intruder detection device of the present invention having the above-mentioned features will be described in detail below with reference to the drawings.

The drawing shows an intruder detection device for a special room for banking operations, that is, a room in which automatic processing machines such as automatic teller machines, automatic exchange machines, and automatic deposit machines are installed.

Figure 1 shows a special room 1, which includes a cash machine 2,
Three automatic currency exchange machines and four automatic deposit machines have been installed.
This special room 1 is provided with an entrance door 5 and a hot spring door 6, which are always closed. Under normal conditions, these doors 5 are closed.
, 6 can be opened to allow users to take a bath.

The above-mentioned automatic processing machines 2, 3.4 are all set to be operable by a card, and the user is allowed to enter the special room 1 using this card.

That is, a card reader 7 is provided on the outer wall of the entrance door 5 and is capable of accepting a card and detecting magnetism or reading a number specifying the bank. 5 will be opened to allow users to enter, and then closed.

A mud switch 8 is provided at the above-mentioned hot water tap door 6 portion, and when the mud switch 8 detects that the user is tapping hot water, the hot water tap door 6 opens, allows the user to tap the hot water, and is then closed.

A person detector 9 is installed in the special room 1 described above to detect the presence of a user in the room. It acts on the entire area (the person detector 9 may be a photoelectric type or other means). Furthermore, a display 10 is provided on the outer wall of the entrance door 5, and this display 10 changes depending on the set time zone. That is, it displays "open for business" from 9 a.m. to 5 p.m., "closes soon" from 4:55 p.m. to 5 p.m., and "closed for business" at other times.

Reference numeral 36 denotes a telephone communication device, which is used to communicate with a bank clerk or a security guard at a central security center, which will be described later, when the automatic processing machines 2, 3.4 are no longer operated.

The above-mentioned intruders into the special room 1 refer to those who enter by forcing open or damaging the doors 5 and 6, and those who enter by breaking the surrounding wall.

The outline of intruder detection in this special room 1 is that when both the mud switch 8 and the human detector 9 have memory devices that remember that there is no user in the room, the human detector 9 detects a human. Accordingly, the detected person is determined to be an intruder, that is, a person who has entered the room illegally.

In addition to the above-mentioned intruder, the person who commits fraud in the special room 1 may also be a person who entered normally through the entrance door 5.

In this embodiment, there is also a means for detecting the above-mentioned fraudulent behavior of a normal visitor, and the general method of detecting this person is to use a timer to set the time that the visitor is present in the room, and to wait for more than this set time. Detects if any residue remains in the area.

The above-mentioned intruders and the above-mentioned remaining persons are monitored by the bank during business hours, that is, from 9 a.m. to 3 p.m. (referred to as on-site monitoring), and at other times by the security company's centralized security center. (referred to as remote monitoring).

The above-mentioned lingering workers include those who remain during business hours, and those who enter the office just before the end of the day and remain after hours, and the remaining workers of their partners are detected.

FIG. 2 shows a control circuit for the intruder and residual person detection device.

The 24-hour repeat timer 11 repeatedly ticks the hour of the day and outputs signals at 9:00 a.m., 3:00 p.m., 4:55 p.m., and 5:00 p.m. Based on these outputs, the display 10 indicates when the business is open, when the business is about to close, or when the business is closed.

The first FF (abbreviation for flip-flop) 12 is set at the 9 a.m. signal A, and reset at the 5 p.m. signal exit.

Therefore, whether the special room 1 is open or closed is determined based on the output states of the first FF 120 set and reset.

The 2nd FF13 was set at signal A at 9:00 a.m., and at 3:00 p.m.
It is reset by the hour signal.

Therefore, depending on the output state of the second FF 130 set and reset, it is determined whether the bank is open or closed, and the on-site monitoring device 14 and the remote monitoring device 15 are switched and controlled based on this determination.

The third FF 16 is set when the human detector 9 and mud switch 8 are empty in the special room 1, and is reset when the card reader 7 accepts a regular card.
Considering that the user may leave without entering the special room 1 even if the card is accepted, it is set even when the person detector 9 does not detect a person even if the entrance door 5 is closed. .

This third FF 160 set output indicates that no one is present in the special room 1 under normal conditions.

Naori-reader I, entrance door drive circuit 17, oscillator 1
8. The automatic processing machines 2, 3.4 are activated by the signal A at 9:00 a.m., and are deactivated by the signal exit at 5:00 p.m.

Next, we will discuss the normal bathing behavior of users.

When the user inserts the card into the card reader 7, the card reader 7 checks the authenticity of the card, and when it determines that the card is legitimate, it emits a signal.The third FF 16 is reset by this signal, and the user is placed in the special room 1. remember that it exists.

(At this point, no users have entered special room 1 yet.

) The entrance door 5 is opened in response to a signal from the card reader 7, and after a time period during which the user can enter, the entrance door 5 is closed and a closing signal is output.

When the user enters the special room 1, the human detector 9 outputs a human detection signal, and the output of the inverter 21 disappears.

As a result, the AND gate 25 is inhibited, so that it does not produce an output due to the aforementioned closing signal, and the third FFI
6 is not set.

At this point, the third FF 16 has accurately memorized the presence of the person in the special room 1.

At the same time, the count timer 19 is disabled due to the loss of output from the inverter 21, so the count timer 1 is activated based on the closing signal of the entrance door drive circuit 17.
9 counts the pulses of the oscillator 18 and measures the time.

This counting timer 19 is set to 5 minutes, which is sufficient time for the user to complete the operation of the automatic processing machines 2, 3, and 4 in the special room 1.

If the user taps the hot water within 5 minutes, a detection signal is output from the mud switch 8, and the hot water door drive circuit 20 opens the hot water tap door 6 based on this signal, and closes the hot water tap door 6 after the time period during which the user can tap the hot water has elapsed. and outputs a close signal.

The person detector 9 stops outputting when the user taps hot water from the special room 1, and the inverter 21 generates an output.

Therefore, when the above-mentioned closing signal is output, an output is generated from the AND gate 26, and this output sets the third FF 16 via the OR gate 27.

Therefore, the third FF 16 has memorized that there is no person in the special room 1.

Next, a case where a person illegally enters the special room 1 will be described.

As mentioned above, when the third FF 15 remembers that there is no person in the special room 1, if a person breaks the entrance door 5 or the hot water exit door 6 and breaks in, or breaks the surrounding wall and enters, the person is detected. The device 9 detects this and outputs a human detection signal.

The human detection signal described above is input to the AND gate 31, and since the set output of the third FF 16 is input to the AND gate 31, an output is generated.

The output of this AND gate 31 is that the third FF 16 is the special chamber 1.
The human detector 9 remembers that there is no one present.
Since this indicates that a person has been detected in the special room 1, it serves as a detection signal for an intruder.

If the second FF 13 is set to output the intruder detection signal while the bank is open from 9 a.m. to 3 p.m., the AND gate 34 opens the gate and sends the intruder detection signal to the field monitoring device 14 manually. be done.

The above-mentioned on-site monitoring device 14 is installed inside the bank and notifies the staff of the presence of a person in the special room 1.

When it is necessary to talk to a person in the special room 1, the person communicates with the person in the special room 1 using the communication device 36 and deals with the situation.

Furthermore, if the bank is closed between 3:00 p.m. when the second FF 13 is reset and 9:00 a.m. the next day at the time when the above-mentioned AND gate 31 outputs the intruder detection signal, the AND gate 35 opens the gate and the remote monitoring device The intruder detection signal is input to 15.

The above-mentioned remote monitoring device 15 is installed in a central security center,
Notify the security guard of the presence of a person in special room 1.

When it is necessary to talk to a person in the special room 1, the person communicates with the person in the special room 1 using the communication device 36 and deals with the situation.

Next, a case will be described in which a visitor who has normally entered the special room 1 remains behind.

As mentioned above, there are two types of stayers: those who stay on time and those who stay after hours. First, let's talk about those who stay on time.

When the entrance door 5 is opened and a person enters, the person detector 9 outputs a person detection signal at that point, the output of the inverter 21 disappears, and the inhibition of the counting timer 19 is released.

When the entrance door 5 is closed, the counting timer 19 is once reset and then started.

In the case of a person who remains within the time limit, the 5 minute time set by the counting timer 19 mentioned above will have elapsed, so the counting timer 1
The time-up signal of 9 is input to the AND gate 28.

Since the AND gate 28 has already input the first FF 120 set output, that is, the signal indicating that business is open, and the human detection signal from the human detector 9, this AND gate 28 detects a person remaining within the time. It will output a signal.

This remaining person detection signal is input to the other games 32 and 33 via the OR gate 30.

The time when the above-mentioned residual person detection signal is output is the second FF 130.
If the set bank is open, ANDGATE 3
2 opens the gate, and the aforementioned residual person detection signal is input to the field monitoring device 14.

Then, the bank staff will deal with the person who remains within this time in the same manner as in the case of detecting an intruder as described above.

Also, the time when the aforementioned residual person detection signal is output is the second FF.
If the reset bank 13 is open, the AND gate 33 opens and the aforementioned remaining person detection signal is input to the remote monitoring device 15.

Then, the security guard at the central security center deals with the person who remains within this time, as in the case of intruder detection described above.

Next, regarding people staying overtime, these people enter before 5 p.m. and stay until after 5 p.m., so the 24-hour repeat timer 11 indicates that the 5 p.m. signal exit is the AND gate. 22, since the human detection signal from the human detector 9 has already been input to the AND gate 22, an output is generated, and the timer 23 is driven by this output.

The above-mentioned timer 23 is set to three minutes, and when this set time elapses, it is determined that the person remains overtime.

For this reason, detection of a person remaining after hours is performed by the above-mentioned timer 23 outputting a time-up signal.

The above-mentioned time-up signal is input to the AND gate 29, and since the human detection signal from the human detector 9 has already been input to this AND gate 29, the AND gate 29 outputs a signal indicating that a person remaining outside of the time has been detected. It turns out.

The above-mentioned overtime residual person detection signal is from ORGATE 30.
The subsequent operation is performed in the same manner as the above-mentioned time remaining person detection.

Note that if the visitor exits the bath before the timer 23 times up, he or she is determined to be a normal visitor.

In this case, since hot water is dispensed before the timer 23 times up, a signal is output from the AND gate 26.

The AND gate 26 outputs a condition when there is no human detection signal from the human detector 9 and the hot water access door 6 is closed, indicating that no person is present in the special room 1.

And the output of this AND gate 26 is the AND gate 24
Since the reset output of the first FF 12, that is, the signal 2 after 5:00 pm has already been input to this AND gate 24, an output is generated, and this output is used as the timer 2.
3 is reset.

In the above embodiment, the residual person detection signal output from the OR gate 30 and the intruder detection signal output from the AND gate 31 are switched and controlled by the AND gates 32 to 35 to the on-site monitoring device 14 and the remote monitoring device 15. However, in each of the devices 14 and 15, in terms of driving the devices 14 and 15, the residual person detection signal and the intruder detection signal operate in the same way without being distinguished.

Therefore, when monitoring detection signals for lingering persons and intruders by distinguishing between them, each device 14 and 15 should operate, for example, a lingering person indicator lamp and an intruder indicator lamp so that they operate in response to the input of respective detection signals. They must be provided separately and must be provided to be indicated by their respective detection signals.

Further, as another means, an example shown in FIG. 3 can be used.

This example shows a remote monitoring device 15, where the residual person detection signal A is the output signal A of the AND gate 33 in FIG. 2, the intruder detection signal B is the output signal B of the AND gate 35 in FIG. Also, the AND gate 37.38 has the 1F in Figure 2.
The set output of the F12 is inputted to the AND gates 39 and 40, and the reset output 2 of the first FF12 shown in FIG. 2 is inputted to the AND gates 39 and 40, respectively.

Therefore, when an output is generated from the AND gate 3γ, the output indicates a person who remains within the time, the output from the AND gate 38 indicates an intruder within the time, the output from the AND gate 39 indicates a person who remains after the time, and the output from the AND gate 40 indicates a person remaining within the time. The output will indicate an overtime intruder.

If the remote monitoring device 15 displays a display corresponding to each of the above-mentioned outputs, the mode of the remaining person and the intruder can be clarified.

Furthermore, in order to prevent fraudulent activities in the special room 1, the special room 1 may be constructed of transparent glass.

In the above embodiment, the card reader 1 is an example of the first detection means, the human detector 9 is the second detection means, the third FFI 6 is the storage means, and the AND gate 31 is the intruder detection means. Each of these is shown as an example, and other configurations may be used as long as they perform equivalent operations.
