Abstract

An elevator system that includes a film sensor is arranged on the inner surface of a wall panel in the elevator car, and a prescribed control operation is performed when the detection output of the film sensor exceeds a prescribed level. This system allows for a quick response to an emergency at low cost, and can be used in a variety of locations without influencing the layout and design of the elevator car.

Claims

1. A type of elevator system comprising:

a film sensor arranged on an inner surface of a wall panel in an elevator car; and

a prescribed elevator car control is performed when a detection output of said film sensor exceeds a prescribed level.

2. The elevator system described in claim 1 wherein said film sensor is made of an electronic/mechanical film sensor.

3. The elevator system described in claim 1 wherein said prescribed control starts an operation of a monitoring camera in the elevator car.

4. The elevator system described in claim 1 wherein said prescribed control stops the elevator car at the nearest floor and opens the door.

5. The elevator system described in claim 1 wherein said film sensor is adapted to detect a vibration, and said film sensor is adapted to output an analog voltage in response to a vibration.

6. The elevator system described in claim 5 further comprising a voltage comparator arranged to receive the analog voltage and compare the analog voltage to a prescribed threshold voltage.

7. The elevator system described in claim 1 further comprising a controller adapted to receive a vibration detection signal.

8. A method of controlling an elevator car, the method comprising:

receiving a vibration detection signal, wherein the vibration detection signal is produced from detecting a vibration at a film sensor at the elevator car; and

stopping the elevator car at a next floor.

9. The method described in claim 8, further comprising:

starting a monitoring camera.

10. The method described in claim 8, further comprising:

making an announcement over a loudspeaker about an emergency condition.

11. The method described in claim 8, further comprising:

keeping an elevator door open for a prescribed length of time; and

closing the elevator door.

12. The method described in claim 8, further comprising:

returning the elevator to a normal operating mode.
