Abstract:

The detection of meshing depth of elevator’s door lock is an important content in the detections of elevator safety performance. Based on machine vision and the principle of image processing, this paper established a detection system of meshing depth of elevator’s door lock, and designed a handheld instrument. Combined with the environment of building for the detection of meshing depth of elevator’s door lock, this paper developed a software system suitable for multiple door locks. The detection system used industrial camera for the image acquisition of door lock’s meshing, and the images would be processed automatically in the micro computer. The instrument is easy to carry. The paper designed two ways including the offline and online automatic calibration for the instrument of video imaging. This paper solved the synchronization problem of image snapshot when the moment of conduction for door lock’s circuit. The detection way has no damage and interference from door lock’s circuit and ensures the independence of detection process.
