In order to measure the motion characteristics of the actuator accurately,an image processing method based on LabVIEW platform is proposed to build a system for detecting the motion speed of the actuator.A high-speed camera is used to capture the motion images of the circuit breaker during the opening process,and the VISION module in LabVIEW is used to locate the motion edges with high accuracy.The motion parameters of the moving end during the motion process is calculated,and the opening capacity of the circuit breaker is evaluated by combining the motion parameters.The experiment results show that the proposed method can achieve accurate detection of the motion parameters of the operating mechanism with the advantages of high accuracy and simple operation,which can provide strong technical support for the study of the breaking capacity of the circuit breaker.
