Abnormal behavior monitoring device for elevators

Abstract

The invention provides an action abnormity monitoring device for elevators, which comprises an image action abnormity detection unit for detecting image action abnormity by performing image processing and resolving of passenger images taken by an in-car camera in an elevator car; a load action abnormity detection unit for detecting load action abnormity when an in-car load sensor detects that the load change in the elevator car exceeds a preset threshold value during running; a threshold value setting unit for setting the threshold value corresponding to the load in the elevator car detected by the sensor; an action abnormity determining unit for determining passenger action abnormity by combination of the detection results from the image action abnormity detection unit and the load action abnormity detection unit; and a reporting unit for reporting a warning message to an in-car playing device disposed in the elevator car when the determining unit determines the action abnormity.

Description

technical field [0001] The present invention relates to an elevator abnormal behavior monitoring device for monitoring abnormal behavior of users (passengers) in an elevator car. Background technique [0002] In the past, there are known monitoring devices with the following functions: when it is detected that the passengers in the elevator car have carried out abnormal behavior, a security camera is installed in the car, and the movement of the passengers in the car is photographed by the security camera. The camera image captured by the device is analyzed, and the abnormal behavior is determined based on the analysis result. [0003] As well-known technologies related to such an abnormal behavior monitoring device for elevators, there are, for example, "operation control device for elevator" (refer to Patent Document 1) and "control device for elevator" (refer to Patent Document 2). "Control device" analyzes the state of passengers in the car by using the image of the cam...

Problems solved by technology

[0008] The technology involved in the above-mentioned Patent Document 1 and Patent Document 2 is a technology that detects, through image processing, damage to objects and acts of violence by passengers in the elevator car as abnormal behavior, and determines that the behavior is abnormal based on the detected result. At the same time, elevator control actions such as broadcasting of warning broadcasts and warning displays for the purpose of preventing crimes are carried out, but it is very difficult to judge abnormal behavior of passengers only through image processing, and it is often wrong to judge and give warnings to elevator passengers may be unpleasant

For example, the actions of passengers in the car tidying their hair in front of the mirror, and the slight movements of passengers wearing striped clothing are not abnormal, but they are misjudged as abnormal behavior due to large fluctuations in image processing. In this case, it is unpleasant to the passengers who normally use the elevator by giving a warning notification as an abnormal behavior.
