Design of Automatic Test Device for Real-time Axle Temperature Detection System of EMU

In order to solve the low debugging efficiency of real-time axle temperature detection system in the debugging process of EMU, an automatic test device is designed for the real-time axle temperature system of EMU. Based on the real-time shaft temperature test logic, the device can exchange data with the digital debugging platform and achieve the automatic function verification of the real-time shaft temperature detection system. In this paper, the overall function of the device is introduced, while the realization of hardware structure and software function is described in detail. The field test results show that the device can meet the requirements on automatic debugging by the real-time axle temperature testing system of EMU, and can effectively optimize the debugging process, while reducing the input of debugging workers. It can significantly shorten the production cycle of EMU, reduce operating costs, and improve production efficiency and quality.
