[0002] A follow-up investigation of the RIOM module in the subway vehicle TIMS system revealed a high failure rate for the RIOM module. Based on actual applications, the power supply board in the RIOM module had the highest failure rate. Disassembly of the power supply revealed a design flaw in the power supply module. Long-term operation could easily lead to low resistance values in some areas, ultimately causing the RIOM module to malfunction. This design flaw necessitated preventive maintenance of the RIOM module in subway vehicles.

This test platform must also have independent hardware control over the on / off switches of each channel. Each channel must be able to display parameters such as voltage and current in real time on both the computer and the test bench. The test bench itself must also have overload and temperature protection, and the power supply must be independently switched on and off.
