The present invention relates to a door opening and closing fault detection method and a detection and early warning system, wherein the method includes: S1. extracting the target area where the target feature on the door is located, and generating a target template based on the target area; S2. Acquiring the position image of the door during the opening and closing process and based on the target template, acquiring the position information of the target feature on the door during the opening and closing process and constructing the running track of the door; S3. The opening and closing fault detection of the door is carried out according to the above running track. The detection scheme is based on the image data of the elevator scene collected by the visual sensor, visual analysis is performed on the device side, the door running trajectory is output in real time, and door abnormality is detected in real time based on the running trajectory, which fully guarantees the safety of elevators and passengers.
Description
technical field [0001] The invention relates to the technical field of elevator safety, in particular to a door opening and closing fault detection method and a detection and early warning system. 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 fault is the fault with the highest frequency among many elevator faults, and there are many types of door faults. The sudden opening of the door during operation may cause passengers to fall, and failure to open the door normally may cause trapped people. Therefore, the door fault Detection and early warning are very important to ensure elevator safety. [0003] With the acceleration of urbanization, high-rise buildings have become the main place for people to ...
