Abstract

The invention discloses a method and system for detecting a tensioning state of an elevator speed governor rope. The method comprises the following steps: obtaining an image of a speed governor rope,wherein the image is shot by an image acquisition module opposite to a tensioning wheel; performing identification processing on the image by using a preset detection model to obtain information of the tensioning state of the speed governor rope; sending the information of the tensioning state outwards and displaying the same on a display device. The method has the advantages that whether the speed governor rope is in an abnormal state or not is recognized through the image acquisition and image recognition processing technology, so that an existing electric safety switch is replaced, and thefaults that an elevator stops abnormally and passengers are trapped due to misoperation of the electric safety switch are avoided.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to a method and system for detecting the tension state of an elevator speed governor rope. Background technique [0002] The elevator speed limiter rope is the bridge connecting the speed limiter and the safety gear. Normally, it follows the car. When the elevator overspeeds, the speed limiter action will block the speed limiter wire rope, thereby driving the safety gear to move and the car It is stuck on the guide rail to ensure that the car does not fall or be thrown up. [0003] According to the elevator technical regulations and standards, the speed governor rope should be tensioned by a tensioning wheel with a counterweight. When the speed governor rope breaks or is excessively stretched, the driving host should stop running. At present, an electrical safety switch with mechanical contact is usually used to detect the tension state of the speed limiter rope. During th...
