In recent years, with the continuous improvement of the running function of EMU and the optimization of the distribution of wires and cables inside the vehicle, the number of wiring test points has increased greatly, and the manual test in the line withstand voltage test has paid more time and cost In order to avoid the influence of manual error on product quality, improve test accuracy and production efficiency, automatic test equipment is used instead of manual test In this paper, the test method of automatic alignment and withstand voltage of EMU is developed. The test reliability is high, and flexible conversion can be completed between different EMU products, which can shorten the test cycle and improve the test efficiency to ensure the production quality of EMU.
