Research on elevator speed governor calibration software based on image processing

As a momentous device to ensure the safety of the elevator operation, the speed governor plays an important protective role of the safety control components in the event of overspeed and rope breaking. In order to judge the action of the speed governor, this article research and develop a software which carries out color processing, statistics and detection on the images according to the photos of the governor. The software can achieve picture browsing and reading function, image processing and parameter adjustment function, statistical results display function and log output function. Through processing the image and outputting the situation of the governor, the software provides professional reference of the elevator safety for the inspector. By comparing the obtained electric action speed with the specified value in the standard, the inspector can judge whether the operation speed of the speed governor meets the requirements.
