Abstract

In this paper, a novel experimental method is proposed in order to verify the availability and reliability in separate system. To measure the position-change caused by the fault-mode machine-separate of the electric isolator plug and to know the real switch process of the important component, the ground separate experiment is required to simulate the real object separate process and to obtain the relative position of isolate component under different separate parameter. In the experiment, a position measurement system based on high speed photograph principle is introduced which has hardware, software and gauging method of photograph measure system. A in-situ measurement system is set up by two high speed camera in order to synchronized image collection of separate process. After extracting, matching, coordinate and position calculating to the image, a relative position of the isolator component at the time of separate process can be deduced. The relative separate speed at this time can be calculated by the position parameter. The measurement system can be tested by the three-axis standard revolving stage. The results of the measurement experiment show that camera response frequency is 1000Hz, the relative error of position measurement is less than 5%, the relative error of speed measurement is less than 5% which can meet demands of experiment.
