Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator monitoring device for monitoring the condition inside an elevator car.

[0002]

2. Description of the Related Art Since an elevator car becomes a kind of closed room during its ascent and descent, even if various illegal acts or mischiefs are performed, it cannot be known from the outside and it is dangerous. Therefore, in order to prevent such illegal acts and mischief, there is conventionally known a device for monitoring the inside of the elevator car with a television camera as described in Japanese Utility Model Laid-Open No. 58-140952. This device has a TV camera in the car of the elevator, transmits the video signal of the TV camera to the monitor TV installed in the elevator hall on each floor, and monitors the inside of the car of the elevator by the monitor TV. It has become. Further, the operation of the monitor television is activated when it is detected by the load detection device that operates when one person is in the elevator car, that the passenger is in the elevator car.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
According to an elevator monitoring device using a monitor television, passengers in an elevator car are monitored by an observer and a large number of people on each floor in the elevator car regardless of their will. There was a problem that it made me feel uncomfortable.

The present invention has been made in view of the current state of the elevator monitoring device as described above, and an object thereof is to enable monitoring in the elevator car according to the intention of the passenger in the elevator car. It is to provide an elevator monitoring device.

[0005]

In order to achieve the above-mentioned object, the present invention provides a television camera provided in an elevator car, a transmission line for transmitting a signal of the television camera, and a transmission line for transmitting the signal from the television camera. In an elevator monitoring device having a monitor television for receiving a signal and displaying an image,
In the television camera, a switch is provided in the car to allow the monitor television to image the situation in the car for a predetermined time.

[0006]

Since the present invention is constructed as described above,
When the passengers can request the monitoring of the inside of the car, and the switch provided in the car is not operated, the TV camera and the monitor TV are stopped. Therefore, the privacy of passengers is respected and the power consumption can be reduced.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to illustrated embodiments.

FIG. 1 is a side view of an elevator monitoring device according to an embodiment of the present invention, and FIGS. 2 and 3 are circuit diagrams of a control device constituting the embodiment shown in FIG. 1 when a switch is not operated.

In each drawing, 1 is an elevator car, 2 is a television camera provided in the upper part of the elevator car 1, 3 is a switch provided on the side surface of the elevator car 1, for example, a monitoring request button, 4 is A monitor television 5 provided in a monitoring room (not shown) is provided in the monitoring room, and a buzzer 3a1 and 3a2 which sounds when the monitoring request button 3 is operated is a normally open contact incorporated in the monitoring request button 3. Reference numeral 6 is a relay that is energized when the monitoring request button 3 is operated, and includes 6a1, 6a2, 6a.
a3 is a normally open contact, 7 is normally energized by a normally open contact 6a2 of the relay 6, and after a certain time period, for example, a time corresponding to 1 minute which is a time required for the car 1 to travel between end floors,
An operating timer, 7b is a normally open contact of a relay (not shown) built in the timer 7, 8A to 8N are monitor televisions provided at each floor (not shown), P and N are DC power supply terminals, and R and T are AC. Indicates a power supply terminal.

Next, the operation of the embodiment will be described.

When a passenger gets into the car 1 of the elevator and wants to monitor the inside of the car 1 from the surrounding conditions, the monitor request button 3 is operated in the state of FIG. 3 to open the monitor request button 3 normally. Contacts 3a1 and 3a2 close, P-3a
The circuit 1-6-N is formed and the relay 6 is energized.
Further, since the circuit P-3a2-5-N is formed, the buzzer 5 provided in the monitoring room sounds and reports to the monitoring staff in the monitoring room that there is a monitoring request. When the relay 6 is energized, the contacts 6a1, 6a2, 6a3 are closed, and P-
Although the circuit 6a2-7-N is formed and the timer 7 is energized, the contact 7b remains closed because the built-in relay (not shown) operates after a certain period of time, and P-7b-
A circuit 6a1-6-N is formed, and the relay 6 is held by itself even after the operation of the monitoring request button 3. Also, as shown in FIG. 3, R-6a3-2-T, R-6a3-4-T, R-6
The circuits a3-8A to 8N-T are respectively formed, and the television camera 2, the monitor room monitor television 4, and the monitor televisions 8A to 8N on each floor (not shown) are activated to enable monitoring.
When the monitoring by the TV camera 2 and the monitor TV 4 in the monitoring room is continued for a certain period of time, the timer 7 operates, the built-in relay (not shown) operates to open the contact 7b, and the relay 6
Turn off. As a result, the contact 6a3 opens, the television camera 2, the monitor television 4, and the monitor televisions 8A to 8N stop, and the monitoring ends.

In the embodiment configured as described above, the inside of the car 1 can be monitored only when the passenger in the car 1 presses the monitoring request button 3, that is, the inside of the car 1 can be monitored unless the monitoring request button 3 is pressed. Can protect the privacy of passengers. Also,
Since the function of the monitoring device does not work unless the monitoring request button 3 is pressed, power consumption can be suppressed.

[0013]

According to the present invention, it is possible to request the passenger to monitor the inside of the car, and when the switch in the car is not operated, the TV camera and the monitor TV are stopped, and therefore the passenger's privacy is maintained. Is protected and power consumption can be reduced.
