Description

  The present invention relates to an elevator control device that detects an abnormality in a car and performs a crime prevention operation.

  In order to detect anomalies in the car and perform crime prevention operation, conventionally, the car is stopped at the nearest floor in response to the anomaly detection in the car detected by the anomaly detection means, and the car arrives at the nearest floor. After the floor, there are doors that open and alarms to notify the occurrence of anomalies, and when the passengers disappear from the passenger car, the elevator is returned to normal operation. The above-described abnormality detection means determines abnormality based on video data taken by a monitoring camera installed in the car, information on a vibration sensor installed in the car, and the like. For example, the difference between the video data when there are no passengers in the car and the video data when there are passengers in the car is determined to be abnormal when the level of the difference data of the video data exceeds a predetermined value. . Alternatively, the vibration level in the car is detected by a vibration sensor, and when this vibration level exceeds a predetermined value, it is determined that there is an abnormality (see, for example, Patent Document 1).

Conventionally, when an abnormality occurs in the car, a vehicle that travels directly to a designated floor such as a manager's room or while stopping at each floor has been proposed (for example, see Patent Document 2).
