A safety elevator based on machine vision comprises a lift car assembly with a lift car frame and a lift car, a lift car guide rail system for providing a lifting guide effect on the lift car assembly, a counterweight assembly, a counterweight guide rail system for providing a lifting guide effect on the counterweight assembly, a traction system and an elevator control cabinet, and an LED white board backlight source is fixed to the top of the inner side wall of a hoistway. A camera and a light supplementing lamp are further fixedly installed in the hoistway, part of the hoisting rope and the LED whiteboard backlight source are located in the photographing range of the camera, the LED whiteboard backlight source forms the photographing background of part of the hoisting rope, and the elevator monitoring system further comprises a monitoring control unit connected with an elevator control cabinet. And the LED whiteboard backlight source, the camera and the light supplementing lamp are in communication connection with the monitoring control unit. The hoisting rope is shot in the lifting operation of an elevator, whether the hoisting rope has the conditions of surface abrasion, corrosion, wire and strand breakage, sudden local thinning, deformation and the like or not can be comprehensively and clearly shot, timely maintenance is facilitated, and safety accidents are avoided.

    一种基于机器视觉的安全电梯,包括具有轿架与轿厢的轿厢组件、对轿厢组件提供升降导向作用的轿厢导轨系统、对重组件、对对重组件提供升降导向作用的对重导轨系统、以及曳引系统、电梯控制柜,井道内侧壁顶部固定有LED白板背光源,井道内还固定安装有摄像头与补光灯,部分曳引绳和LED白板背光源都位于摄像头的摄影范围内,并且LED白板背光源构成部分曳引绳的拍摄背景,还包括与电梯控制柜相连接的监测控制单元,LED白板背光源、摄像头、补光灯与监测控制单元相通信连接。在电梯升降运行中对曳引绳拍摄,能够全面地清晰地拍摄出曳引绳是否出现表面磨损、锈蚀、断丝断股、局部突然变细、变形等情况,便于及时维护,避免引发安全事故。
