Abstract

PURPOSE:To easily specify an intrusion monitoring area by segmenting the intrusion monitoring area of a wide range into plural intrusion monitoring areas, and providing a monitoring control means for raising an alarm at the time when the generation of an intrusion is detected at every intrusion monitoring area. CONSTITUTION:When a tenant of an intrusion monitoring area A leaves a room he allows the card reader of the outside of the room to read his own ID card, and when it coincides with an ID number recorded in an ID number memory 12, a monitoring lamp L13 is turned on. When all the areas are in an intrusion monitoring state, when an intrusion is generated in the area A, and a sensor output S22 is inputted to an OR circuit 40, a periodical pulse signal is inputted to an intrusion pilot lamp L5 and a buzzer B1 of a monitoring board 50 through an OR circuit O42, and also, an intrusion detecting signal is inputted to an automatic dialing device 41 through an OR circuit O4, by which the generation of the intrusion is informed automatically to monitoring sensor 51 by telephone. In such a manner, among plural monitoring sensors, which sensor is operated can be known easily.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a crime prevention system that divides the intrusion monitoring area in one room into a plurality of small areas and performs intrusion monitoring for each area or the entire room. .

[Conventional technology]

Conventionally, in buildings such as office buildings where tenants leave their rooms at night and the rooms become unoccupied, when the last tenant leaves their room, they close the windows, etc. and then set an intrusion monitoring sensor and leave the office. did. Or, after locking the door, operate the key in the key box in your room inside the security box installed at the side entrance of the building,
The intrusion monitoring sensor installed in the room was activated to monitor intrusion at night.

(Problem to be solved by the invention) Conventionally, measures to prevent intrusion inside a building have been taken as described above. As a result, a tenant who closes the door and leaves the room at the end may overlook the door being closed, or even if the tenant notices the detection signal output from the intrusion monitoring sensor, which of the multiple windows is not properly locked and the intrusion monitoring is performed. It was unclear whether the sensor was working or not, and it took a long time to resolve the door locking issue. Furthermore, if you leave your room and activate the intrusion monitoring sensor in your room by operating the key on the security box at the side door, if the intrusion monitoring sensor has already outputted an intrusion detection signal, there is the inconvenience of returning to your room again. At the same time, problems such as unfavorable crime prevention were also solved.

This invention was made to solve the above-mentioned problems, and it is possible to easily determine which of the multiple intrusion monitoring sensors is activated, and also to check the intrusion monitoring system immediately after closing the door of one's own room. The purpose is to obtain a crime prevention system that can.

[Means to solve the problem]

The crime prevention system according to the first aspect of the present invention includes an intrusion monitoring area of a room having a plurality of doors divided into a plurality of areas corresponding to each door, an intrusion sensor installed in each area, and an intrusion sensor installed in each area, and an intrusion monitoring area corresponding to each door. A monitoring control means for each door that inputs a detection signal from a sensor and displays the intrusion monitoring status, and an area intrusion system that notifies that an intrusion has occurred in a predetermined area when an intrusion detection signal is input from a predetermined monitoring control means. The room intrusion notifying means notifies the occurrence of an intrusion into an unoccupied room when a detection signal is inputted to all the monitoring and controlling means and an intrusion detection signal is inputted from a predetermined monitoring and controlling means.

In addition, the prevention system according to the second invention divides the intrusion monitoring area of a room having multiple doors into multiple areas corresponding to each room, and uses an intrusion sensor installed in each area, and an intrusion sensor that is activated when the door closes. A display section that inputs a detection signal and displays the intrusion monitoring status, inputs a detection signal from another intruder sensor, and displays the intrusion detection signal separately from the intrusion detection signal input from the own intrusion sensor when the intrusion detection signal is input. It is equipped with monitoring and control means for each field.

[Effect]

According to the first invention, when a tenant who has a department in each intrusion monitoring area in the room finally exits his or her department, the tenant monitors the intrusion by operating the monitoring control means installed corresponding to the intrusion monitoring area. By setting the sensor, you can check the intrusion monitoring status immediately after leaving. Therefore, if tenants in each department operate their respective monitoring and control means, all the intrusion monitoring sensors in the room will eventually be set, and the intrusion monitoring state for the entire room will be in place. This eliminates the trouble of having to check that all the doors in the room are locked for the tenant who is the last to leave the room, and the number of check errors is reduced. Furthermore, since the intrusion notification format is different depending on whether the tenant remains in another department in the room or when the room is unoccupied, the staff can be made to carry out appropriate intrusion occurrence processing.

Further, according to the second invention, when the tenant operates the monitoring control means to set the intrusion monitoring sensor when leaving his/her own department, the detection signal of the already set intrusion monitoring sensor of another department is received. Therefore, even if the intrusion monitoring sensor is activated due to a door not being properly locked in another department, the door can be completely locked immediately upon noticing the door being not properly locked.

In Fig. 2, (1-1) to (1-4) are the intrusion sensors set in the multi-windows (Wll) to (Wi4) of the tenant part ffl (R), and (CRY) is the intrusion sensor signal. Enter the card reader described above, (Dl) is a door with an electric mirror, (2-1) to (2-4) are also set to multi-windows (W21) to (W24) in the tenant room (R). The intrusion sensor (C1h) is a card reader that inputs the intrusion sensor signal, and (D2) is a door with an electric mirror. For each of the above card readers (CRI) and (CRY), see Figure 2 (b).
As shown.

Light at θ (L++), NG light (S + z) Monitoring 9 lights (L1
3), sensor light (LI41 and card lead part (11)
) are provided for each. In addition, a card reader (C
The same applies to R2).

Next, the operation of this embodiment will be explained based on the above configuration. First, when a tenant whose department is located in intrusion monitoring area A leaves the room, a card reader (CR) is installed outside the room to record the tenant leaving the office.
Have i read your own ID card. When the I11 number of this ID card matches the IC number recorded in the ID number memory (12), a signal is output from the match detection section (13) to the monostable multi (15), and the monostable multi (1
5) Outputs the lighting output to the light (L++) at 0, and
A negative pulse is also output to TF/F (Ql). As a result, the Q terminal output of TF/F (Ql) goes out and the - hour monitoring light (L13) goes out, but when the door (Dl) is closed, the electric door lock is locked and the 9 monitoring lights (L13) are turned off. lights up again. However, if the sensor light (L14) in your area lights up immediately after closing the door (DI), this means that one of the windows (Wz) to (Wi4) in your area is not properly locked. H” level sensor output (512
) is input to the AND circuit (eye A) together with the "H" level monitoring signal (SZ), and the sensor lamp (L14) 5 is turned on. Tenants who noticed this should re-enter the ID
When the card is read by the card reader (11) and it is determined that the ID numbers match, the 0 light (L++) lights up, and then an electric lock release signal (S+) is sent from the Q terminal of TF/F (Ql). ) is output to the electric lock. At this time, the Q @ child ratio output goes out, so the 9 monitoring lights (L12) and the sensor light (L14
) goes out. After unlocking the electric lock, the tenant enters the room, completely locks the multiple windows (Wll) to (Wi4), then goes outside and locks the electric lock. As a result, the "H" level signal is input from the Qe4 to the A terminal of the AND circuit (All), but the sensor output (512) is input to the B terminal unless the intrusion sensor is activated, so the sensor light turns on. There's nothing to do. This allows the tenant to check whether the door is locked immediately after closing the door.

However, if intrusion monitoring is canceled in intrusion monitoring area B and a tenant in intrusion monitoring area A opens the window of intrusion monitoring area A while returning home and an intrusion occurs, the monitoring signal (SZ ) is input to the ANI) circuit (Al1
) inputs the sensor output (512) and passes the intrusion detection signal through the OR circuit (041) to R-5F/F (Q4
Output to A). As a result, R-5F/F (Q4A
)'s qAlAl force output becomes H'' level output and A'ND
It is input to the AJM child of the circuit (A42). AND circuit (
The B terminal (negative input) of A42) is currently R-3F.
Since the "S" level signal from /F (Q4B) is being input, the AND output is output to the monitoring board (50) through the OR circuit (042), and the intrusion indicator light (L,) notifies the guard that an intrusion has occurred. A lamp will be displayed on the button, and an alarm will be output on the buzzer (at). In addition, the intrusion detection signal output from R-5F/F (Q4A) is input to the automatic timetable device (41) through the OR circuit (044).
The occurrence of an intrusion is automatically notified by telephone to the monitoring center (51) via the line network (50). In this way, by notifying the supervisor of the occurrence of an intrusion, the supervisor can go to the area where the intrusion has occurred and also notify other remaining tenants of the occurrence of the intrusion, allowing them to quickly respond to the occurrence of the intrusion. Can be done.

On the other hand, if both tenants in intrusion monitoring areas A and B have set up intrusion sensors and returned home, then the card reader (C
RY), TF/F of (C:R2) (Ql), (Q2)
From l, the monitoring signal (511) and (521) are ANDed.
AN because it is input to A and Be1M of the circuit (A4G)
[An H" level signal will be input to the B terminal of the first circuit (A44). In this way, when all areas are in the intrusion monitoring state, an intrusion occurs in area B, and the sensor output (5
22) is input to the B terminal of the OR circuit (40), AN
An “H” level signal is input to the A terminal of the D circuit (A44), and the ANIJ output is R5-F/F (44[1) k:
A signal is output from the input terminal Q to the pulse generator (40). As a result, the periodic pulse signal is converted into an OR circuit (0
42) through the intrusion indicator light (L5) of the monitoring panel (50),
This is input to the buzzer (Bl), and an intermittent lamp display and intermittent buzzer sound notify that an intrusion has occurred in an unoccupied room. In addition, the intrusion detection signal output from the R-5F/F (Q4A) is input to the automatic dialing device (41) through the OR circuit (044), and sent to the monitoring center (51) via the NTT line network (50). ) will be automatically notified by telephone of the occurrence of an intrusion. In this way, by notifying the supervisor of the occurrence of an intrusion, the supervisor can go to the area where the intrusion has occurred and quickly deal with the occurrence of the intrusion.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is an overall configuration diagram of the crime prevention system according to this embodiment. In the figure, the same reference numerals as in FIG. 1 indicate the same parts, and detailed explanations will be omitted. (Alla) in card reader (Ill:R1), (CR2)
, (^23.), (Al1), and (A23) are AND circuits, (17L (27) is a pulse generator that generates a pulse train signal, and (0,.) and (02°) are OR circuits. Each card reader uses these circuit configurations to output an intrusion detection signal in its own intrusion monitoring area and a sensor output (S+□) or (S'3) in another intrusion monitoring area.
) can be distinguished and displayed on the sensor light (L14) or (L24). The tenant rooms to which this security system is applied are similar to those shown in FIG. 2(a).

Next, the operation of this embodiment will be explained based on the above configuration. First, when a tenant whose department is located in intrusion monitoring area A leaves the room, a card reader (C
RY) to read their own ID card. This ID
When the ID number of the card matches the ID number recorded in the ID number memory (12), a signal is output from the match detection section (13) to the monostable multi (15), and the monostable multi (
Work 5) outputs a lighting output to the OK light (t, z), and
A negative pulse is also output to TF/F (Ql). As a result, the Q terminal output of TF/F (Ql) disappears and the temporary monitoring light (L12) goes out, but when the door CDI) is closed, the electric lock on the door is locked and the monitoring light 9 (L's) is turned off. It lights up again. However, if the sensor light (L14) in your area lights up immediately after closing the door (Dl), this means that one of the windows (W++) to (WI4) in your area is not properly locked. H” level sensor output (512
) is A along with the “H” level monitoring signal (S++).
After being input to the ND circuit (All-), the OR circuit (0+0
) to the sensor light (L14).
This means that 4) has been lit. The tenant noticed this and sent the ID card again to the card reading section (11).
If it is determined that the ID numbers match, the OK light (L++) lights up, and then the electric lock unlocking signal (Szo) is output from the Q terminal of TF/F (Ql) to the electric lock. At this time, the monitoring signal (Sz) at the Q terminal goes out, so the nine monitoring lights (L13) and the sensor light (L14) go out. After unlocking the electric lock, the tenant enters the room and opens the multiple windows (W++).
~ (W14) After completely locking the door, go outside and lock the door with the electric lock. As a result, an AND circuit (^3.
), an "H" level signal is input from the Ql element to the A terminal of the BeJ element, but unless the intrusion sensor is activated, the sensor output (512) is input to the BeJ element, so the sensor light will not light up. This allows the tenant to check whether the door is locked immediately after closing the door.

However, when the tenant in the intrusion monitoring area A closes the door of his/her room, the sensor light (Li2) of the card reader (CRY)
) starts blinking, this means that one of the windows (W2+) to (W24) in the adjacent intrusion monitoring area B is not properly locked, and the intrusion monitoring sensor outputs a sensor output (S2□).
is the AND circuit (to which the monitoring signal (521) is input)
A22), and the AND output is sent to the card reader (CRY
) of the AND circuit (^1.) (at this time, the monitoring signal (S++) is input to the A terminal).
Input the ND output to the pulse generator (17). and,
The pulse train signal flows through the OR circuit (0, .) to the sensor light (Li2) of the card reader (CRI). As a result, the tenant sees the blinking display of the Senna light (Li2) and notices that the window in the adjacent area has a defective door lock.

Furthermore, we will explain the intrusion monitoring operation after the tenants in each intrusion monitoring area A and B set their intrusion sensors and return home.
First, the electric locking command for each TF/F (Q□), (lh) is output, so each monitoring signal (Sth), (5
12) is input to the A and B terminals of the AND circuit (A3°), and an H" level signal is input to the B terminal of the AND circuit (A31).At this time, if an intrusion occurs in the intrusion monitoring area A, the card reader The sensor light (Li2) of (cRl) lights up, the sensor light (L24) of the card reader (CR2) blinks, and the sensor output (S++) is input to the A terminal of the OR circuit (03°), and the OR output is an AND circuit (S3
Input to the A terminal of 1). This causes an intrusion alarm signal (
S31) is output from the AND circuit (A31) to the building management room. Further, although not shown, similarly to the first invention, the security insurance company may be automatically dialed in response to an intrusion alarm signal to notify the occurrence of an intrusion. The above operation is the same even if an intrusion occurs in the intrusion monitoring area B.

Also, when the tenant is dispatched, when the ID card is read by the card reading section (11), if the number 10 has been registered, the light (L++) lights up at 0, and then the TF/F (Ql
) The electric lock unlocking command is output from the Q terminal and the electric lock is unlocked. At this time, the monitoring signal (Sz) of the Q terminal disappears, so the nine monitoring lights (L12) go out, and the inputs to each AND circuit (A -), (^1.), (A3o) become "L". ”
level, and intrusion monitoring is discontinued.

As described above, the tenant in each intrusion monitoring area can also check whether the door in the adjacent area is locked when the door is locked.

The present invention is not limited to the above-mentioned embodiments, and the same effects can be achieved even in the following embodiments.

(1) The number of card readers is not limited to two, but a large number may be added.

(2) All intrusion sensors may be treated as one without determining the intrusion sensor area for each card reader, and in particular, the sensor indicator light may be integrated.

(3) I configured intrusion monitoring to be performed when all card readers are on guard, but if only a small area of my own is on guard, intrusion monitoring is performed only in that small area, and when all area intrusion monitoring is performed. It is also possible to use different intrusion notifications and rank intrusion monitoring.

(4) The card reader can also be used with a key switch, numeric keypad, etc., or an ID recognition device.

(5) The same can be done with automatic doors instead of electric locks.

〔Effect of the invention〕

As described above, according to the present invention, the intrusion occurrence area can be easily identified even in a wide intrusion monitoring area, and furthermore, the intrusion monitoring status can be confirmed immediately after setting the intrusion sensor of the predetermined intrusion monitoring area, and the Since the intrusion monitoring status of the intrusion monitoring area can also be grasped, the crime prevention effect is improved.
