Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator crime prevention device.

[0002]

2. Description of the Related Art Conventionally, as an example, Japanese Patent Laid-Open No. 61-192685 has been proposed in order to prevent crime associated with the use of an elevator.

This is because when a person comes within the monitoring range of the hall, the sensor detects it and activates the television camera for the hall.
On the other hand, a TV call for a car is activated by a hall call.

[0004]

In the above prior art, the operation of the hall TV camera requires a sensor for detecting a person, which increases the cost, and the operation of the cage TV camera is responded by a hall call. Therefore, for example, when three cars are arranged side by side, when the user uses another car other than the one initially assigned, the TV camera for this car does not work.

An object of the present invention is to surely operate the hall TV camera when there is an elevator user without providing a sensor, and to surely operate the car television camera when riding in a car. An object is to provide a crime prevention device for an elevator that can do this.

[0006]

In order to achieve the object of the present invention, a hall television camera for monitoring a predetermined range of the hall is provided in the hall of the elevator, and a user is monitored in the car. In an elevator crime prevention device having a car TV camera, the hall TV camera is configured to operate in response to a floor call when a user registers a hall call and when a car call is pressed. In addition, the car television camera is configured to operate when a user presses a car call.

[0007]

In the present invention, when the elevator user presses the hall button, the hall television camera is activated, and at the same time, the alarm means is activated to monitor the television monitor and the destination floor button in the car is depressed. When the destination floor button is pressed, the car TV camera in the car operates and broadcasts it on the TV monitor,
When the car arrives at the destination floor, the hall TV camera on the arrival floor is activated.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a cross-sectional view of an elevator and a hall, showing an example applied to three elevators. FIG. 2 shows a vertical sectional view of an arbitrary car in the elevator shown in FIG. FIG. 3 shows an electric circuit diagram of this embodiment.

In FIGS. 1 and 2, 1 is a hall, 2 is a hall television camera provided at a position where the hall 1 can be monitored,
3 is a hall button provided on the hall wall 9, 4 is an elevator car surrounded on three sides by elevator side plates 10, 5 is a television camera for a car provided on the car 4, and 7 is provided on the front side plate 16 of the car 4. A car operation panel, 6 is a destination floor button of the car operation panel 7, and 8 is an elevator user. Also, 14
It shows a landing door that engages with the car door 15 and opens and closes. In addition, in the present embodiment, the car television camera 5
It is provided near the basket ceiling 11 and has a basket ceiling 1 and a lighting 12
It is installed between the car and the lighting cover 13 to monitor the inside of the car 4.

Now, when the elevator user 8 pushes the hall button 3 to use the elevator, the hall TV camera 2 is activated to start monitoring the hall 1. The car 4 arrives in response to the hall call, the doors 14 and 15 are opened, and the user 8 enters the car 4
When the passenger gets in the car and presses the destination floor button 6, the car television camera 5 in the car 4 in which the destination floor button 6 is pressed operates and the inside of the car 4 is monitored. When the car 4 arrives at the destination floor, of the hall TV cameras 2 provided in the hall 1 on each floor, the hall TV camera 2 on the floor where the car 4 arrives operates to start monitoring the hall 1 on the arrival floor. .

In FIG. 3, reference numerals 2A to 2N denote the power sources of the television cameras for halls installed in the halls, and 5A denotes the power source of the television cameras for cars in the car 4 in which the user 8 gets in. 71a to 7Na are timed relays 71 to 7 that are activated at the same time when the landing button paired with the landing button on each floor is pressed.
N (not shown) each a contact, and timed relays 71 to 71
7N deactivates after a certain period of time when the circuit opens. 91a ~
9Na is a pair of relays 91 to 9N (not shown) that are energized when the car 4 arrives paired with the floor where the car 4 arrives.
The contact point, Ta, is energized when the door 15 is opened after the car 4 arrives at the destination floor, and is de-energized after a certain period of time when the door 15 is closed later. Is. 51a to 5Na are a-contacts of relays 51 to 5N (not shown) that are energized in a pair when any of the destination floor buttons 6 in the car 4 is pressed, and the relays 51 to 5N are intended for the car 4. Deactivates when the door 15 closes after arriving on the floor.

Now, when the elevator user 8 presses the landing button 3 on the first floor, the timed relay 71 is energized, and the a contact 71a of the timed relay 71 is closed, and the first floor hall TV camera 2
A operates. When the car 4 arrives and the user 8 gets into the car 4 and presses the second floor button of the destination floor button 6, the relay 52 is energized, the a contact of the relay 52 is closed, and the car where the destination floor button 6 is pushed. The 4th cage TV camera 5A operates. On the other hand, when the car 4 arrives and the timed relay 71 energized by the hall button 3 is deactivated with a timed limit, the timed relay 71 is deactivated when the car destination floor button 6 is pressed, and the a contact 71a
Opens, and the hall TV camera 2A on the first floor finishes monitoring. When the car 4 arrives at the second floor by the second floor button of the destination floor button 6, the relay 92 is energized and the a-contact 92a is closed. Next, when the door 15 of the car 4 is opened, the timed relay T is energized, the a contact Ta is closed, the second floor hall TV camera 2B is activated, and the user 8 is monitored after getting off to the second floor hall. I do.
Further, the time-relayed relay T is de-energized for a certain period of time after the door 15 of the car 4 is closed and the a contact Ta is opened. The monitoring by 2B is completed. On the other hand, when monitoring the inside of the car by the car TV camera 5A, the door 15 is closed after the user 8 gets off the car 4, the relay 52 is deactivated, and the a contact 5
2a opens and the monitoring ends.

In this way, when there is an elevator user 8, the hall TV camera 2 and the car TV camera 5
The movement of the user 8 is tracked and monitored in accordance with the series of movements of the user 8.

[0015]

According to the present invention, without providing a sensor, when there is an elevator user, the hall TV camera is surely operated, and the car television camera is surely operated when the passenger gets on the car. Since it can be operated and the user's movement state can be tracked and monitored, there is an effect that an inexpensive and reliable elevator security device can be provided.
