Abstract

PURPOSE:To keep a crime prevention effect by a method in which elevator service is prohibited by detecting the unmanned condition of each floor by ID discriminators set in each room and also allowed to operate for a given time period by ID discriminator for passers in building. CONSTITUTION:ID discriminators 1a-1n are set in each room of a building, and an ID discriminator 3 is also set at the gate of the building. The discriminators 1a-1n are connected to a service prohibitor 2 and the discriminator 3 is connected to a service activator 4. The unmanned condition of each room is detected by the device 2 from the operating condition of the discriminators 1a-1n to prohibit elevator service for the unmanned floor for a given time period. When ID discrimination of a passer in the building is made by the device 3, the prohibition for a given time period of the device 2 is released by the activator 4. Elevator service can thus be provided as the crime preventing system is being kept.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a crime prevention system that prohibits elevator service for each floor of a building depending on the exit time and prevents intrusion into unmanned rooms. It is.

[Conventional technology]

Since the tenant building becomes unoccupied after the tenant 1 on each floor leaves the building, it is possible that a suspicious person will take advantage of the unoccupied condition and invade the office from outside, ransacking the tenant's rooms. For this reason, conventionally, after the tenants of each floor have left, elevator service has been provided in order from the floor where the tenants have completely left, in order to prevent people from outside from easily accessing each floor. The ban was lifted in time for dispatch the next morning. This results in
The unmanned building made it impossible to easily access each floor.

[Invention or problem to be solved]

Conventional building security systems restrict elevator operation as described below, and the prohibition on elevator service is lifted only at a certain time the next morning. In the case of a building where people come and go 24 hours a day, the problem is that a security system that sets a time period during which elevator operation is prohibited is not practical.

This invention was made in order to solve the above-mentioned problems, and aims to provide a security system for a building that maintains the crime prevention effect and is available 24 hours a day.

[Means to solve the problem]

The crime prevention system according to the present invention detects an unmanned state on each floor based on the operation status of an ID discrimination device installed in each room of a building, and prohibits elevator service on unmanned floors for a predetermined period of time based on the detection result. service prohibition means and ID recognition device installed at the side entrance of the building.
The present invention is provided with a service activation means for making use of an elevator service whose service has been prohibited based on a determination result for a predetermined period of time.

[Effect]

According to this invention, the service prohibiting means determines whether a tenant on each floor has left based on the operating status of the ID discriminating device on each floor, and as a result, prohibits elevator service as the floor is unmanned. When the ID discrimination device at the side entrance of the building discriminates the ID of a person passing by the building, the service activation means activates the elevator service to the building passer's room or a certain floor, as opposed to the service prohibition means. It is something.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is an overall configuration diagram of this embodiment. As is clear from the figure, this embodiment detects the unoccupied state of each floor from the operating status of the ID discriminating devices (1a) to (1n) installed in each room of the building, and based on the detection results. Unmanned floor

Means (4) is provided.

Figure 2 is a schematic diagram of a tenant building to which this embodiment is applied.Tenants in this tenant building (B) usually enter through the building's side entrance (Dl) and use the elevator (E) to access each floor. = (F2) to (F3). At the entrance/exit (DI) of each tenant's room, a card reader (CR11) is installed near the door (D2) in the arrangement shown in Figure 3.This card reader (cR+) is attached to a reader head (R). It) seizes the tenant's ID cart and displays the result (ID discrimination OK or NG) on the display (DSL). ID
Once the ID has been determined by the cart, the electric g (EKI) of the door (D2) will be unlocked and the door (D2) will be unlocked by turning the knob.
D2) is open. In addition, each tenant's window (W) is provided with an intrusion sensor (S) that detects intrusion from the outside by detecting crow breakage and window opening, as shown in FIG.

Cart reader (CR) provided for each tenant above
As shown in Figure 5, I) includes a cart reader head (R 1) that reads the ID cart, a memory that stores the ID number of the person who is permitted to enter the tenant's room, and an electric lock unlocking program. (Ml), performs ID discrimination processing,
A display device (DSL) that displays the determination result by the CPU (C1), which outputs an unlock command based on ID determination or processes various monitoring signals, and indicates that the intrusion sensor (S) is monitoring. , command to unlock the electric lock (cK+),
It consists of a sensor signal from an intrusion sensor (S) and a human output interface (IO+) that outputs a monitoring signal.

Card reader (CR2) installed at the side entrance (D,)
The cart reader (CRI) is similar in configuration to the above-mentioned cart reader (CRI), but as shown in Figure 6, it has a clock part (T) that tells the unlocking time and locking time of the electric M (EK2), and a clock part (T) that informs each floor. Relays (Ry+) to (Ry) that control elevator operation
o) and a human output interface (IO2) that outputs signals to the electric lock (EK2).

Next, the operation of the electric lock unlocking command program processed by the CPU (C+) of the cart reader (CRY) provided at the tenant entrance door (D2) will be explained based on the flowchart shown in FIG. First, it is determined whether the ID card has been read by the cart reader (CRI), and if it is determined that the ID card has not been read, the sensor signal from the intrusion sensor (S) is manually input to determine whether or not an intrusion is being monitored. , If the intrusion monitoring is stopped, the ID cart is read by the cart reader (CRI) again (4
-1), (4-2).

If it is determined that the ID cart is read in (4-1), then I
It is determined whether the ID number in the D card is a number that is permitted to enter the tenant's room, and if it is not a permission number, an NG display will be displayed on the display (DSL) in the cart league (CR+) for a few seconds (4 -3), (4-4). Or (4-3
), if it is determined that it is a permit number, the display CD5L
) for a few seconds 4-5), and at the same time, a sensor signal is manually input from the intrusion sensor (S) to determine whether or not intrusion monitoring is being performed (4-6). If an intrusion is being monitored, even if the ID number is a permit number, issue an electric lock lock command and lock the electric lock (EKI) (4-7), (4-
8). This prevents people from freely entering the tenant during intrusion monitoring. After locking the electric lock, the elevator service prohibition relay (
(4-9), (4-10). Furthermore, if it is determined that the intrusion sensor (S) is being monitored in step (4-6), the monitor signal is displayed on the display (os'), the sensor signal is read from the intrusion sensor (S), and the sensor signal is read from the intrusion sensor (S). Check whether it has worked (4-11), (4-12). If the intrusion sensor (S) does not work, sell 8 ID cards (4-1) again. Furthermore, if the intrusion sensor (S) is activated, an external alarm is output indicating that an intruder has occurred, and a bell is also rung in the manager's room (4-13), (4-14).

Alternatively, if it is determined in (4-6) that the elevator is not being monitored, the elevator service prohibition relay (Ryo) is deactivated, an electric lock unlocking command is issued, and the electric lock (EKE) is activated.
) to unlock (4-16) to (4-19). With the above operations, people can freely enter the tenant. Further, since it is not determined that monitoring is in progress, the monitoring display on the display (DSL) is turned off (4-20).

Next, a cart reader (
The operation of the electric lock unlocking program processed by the CPU (G2) of CR2) will be explained based on the flowcharts shown in FIGS. 8(a) and 8(b).

First, when the electric lock (F, 2) on the side entrance is unlocked, issue an electric lock unlock command and unlock the electric lock (EK2) (5-11, (5-2+) .Next, electric lock (EK
If the locking time d is determined, an electric lock locking command is issued and the electric lock is locked (5-4) to (5-6). This side entrance electric lock TJI! Due to i&i, people cannot freely pass through the building. If you have the cart reader (CR2) at the side entrance (Dl) sell 8 ID carts at the time when the electric lock is locked, in order to go to the floor where the tenant or your room is located, It is determined whether the number is a passable or permitted number, and if the number is not permitted, an NG display will be displayed on the display (052) of the cart reader (CR2) for a few seconds (5-7) to (5-9) . Also, if it is an ID number or a permit number, press (5-10) to display OK on the display (052) for a few seconds and check the electric lock (EL) that is locked.
Issue a command to unlock at - time and unlock the electric lock (EK2) of the side entrance at - time (5-11), (5-12). Furthermore, from the ID number, determine whether the tenant's room is 2V4J or 3ya.
If it is on the 3rd floor, operate the relay (Ry3) shown in the sequence circuit diagram in Figure 9 for 20 minutes, open the contact of the relay (RY3), and set the elevator service prohibition relay (on the 3rd floor).
With CUT3) inactive, the tenant can freely take the elevator to the third floor (5-13), (5-14).
Alternatively, if it is determined from the ID number that it is tenant 1-'s room or the second floor, operate the relay (RY2) for 20 minutes, release the contact of the relay (Ry2), and relay the elevator service prohibition relay for the second floor. (CUT2) is deactivated and the tenant uses the elevator to go to the second floor (5-1).
3), (5-15). After operating the elevator for 20 minutes, check whether the electric lock (EK2) of the access door is ready to be released (5-16).

Due to the side door unlocking operation described in -1- below, even after the time when Eleheta service is prohibited, the tenant will be able to access the ID.
You will be able to go to your room using the Eleheta service based on ID identification based on the number.

The present invention is not limited to the above embodiments, and similar effects can be expected with the following embodiments.

1 In this implementation, the number of floors of the building was 3, but it can be implemented in the same way if the building has many floors.

2 In this implementation, the number of elevators is one, or the number of elevators is large.

3. The same applies when there are multiple tenants on one floor for a long time. When all tenants are being monitored, the elevator service is killed, and when a person from the corresponding tenant enters from the side entrance,
The shift is fine so that the elevator service on that floor can be utilized for a predetermined period of time.

4. The same thing happens with automatic doors instead of electric locks.

5 When someone enters from the side entrance, all floors of the elevator
may be provided as a service.

6 ID identification devices other than cart readers (numeric keypad, IC
Cards, fingerprint verification devices, contactless ID carts, etc.
may be used alone or in combination with a plurality of ID discriminating devices.

7. The same effect can be obtained even if the hall call and the car call on the first floor are kept active at all times.

8. If there is a lot of people coming and going after the side entrance is closed, you can temporarily cancel the closure and make use of the elevator service.

9. The service time of the elevator may be set not only to 20 minutes but also to other service times.

〔Effect of the invention〕

As described above, according to the present invention, the I
Based on the D determination result, the configuration is configured to take advantage of the elevator service to the floor to which the exit requester belongs, so it is possible to protect the security system of the building where people come and go 24 hours a day, and it also reduces the time when the service is prohibited for building users. This has the effect of providing an elevator security operation service that is easy to use and does not require consideration.
