A method and system for detecting elevator trapped people based on intelligent video analysis technology

Abstract

The embodiment of the invention discloses an elevator person trapping detection method and system based on an intelligent video analysis technology. The method comprises the following steps that an elevator passenger detection network based on deep learning is acquired; a video acquisition sensor collects elevator scene image information and sends the elevator scene image information to an elevator passenger safety detecting unit; a speed sensor collects elevator running speed information and sends the elevator running speed information to the elevator passenger safety detecting unit, or an elevator fault signal is sent to the elevator passenger safety detecting unit; if a current elevator door is in the normal open state, the elevator passenger safety detecting unit performs no-trapped-person judgment; and when the current elevator door is in the closed state, the elevator passenger safety detecting unit performs the following processing that elevator passenger detection network detection and foreground extraction are carried out, data transmitted in by the speed sensor is used in cooperation, if the elevator speed is less than a set threshold and the elevator passenger safety detecting unit detects that some one exists continuously within set time, person trapping alarming is carried out, or no-trapped-person judgment is carried out.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, and in particular relates to an elevator trapped person detection method based on intelligent video analysis technology. Background technique [0002] Elevator is a very popular public facility. It is widely used in shopping malls, office areas, residential areas and other scenes. It brings great convenience to people's daily life. However, due to factors such as incorrect use and untimely maintenance , the elevator occasionally fails. Door failure is the most frequent failure among many elevator failures, and there are many types of door failures. Among them, the failure of the elevator to open the door may lead to trapped people. [0003] Generally, monitoring equipment such as cameras will be installed in the elevator. The traditional monitoring system will have staff monitoring 24 hours in the monitoring center. Once any dangerous behavior occurs, it should be rescued in time. Howeve...

[0003] Generally, monitoring equipment such as cameras will be installed in the elevator. The traditional monitoring system will have staff monitoring 24 hours in the monitoring center. Once any dangerous behavior occurs, it should be rescued in time. However, due to fatigue or other factors, the actual situation of the staff cannot Respond in a timely manner, which can easily lead to hazards
