Optimization of remote I/O module(RIOM)grounding mode used in high-speed EMU
To study the high communication failure rate of remote I/O module used in EMU,effectively reduce the failure rate and improve the punctuality of EMU,the control principle of remote I/O module is firstly analyzed,the typical failure of remote I/O module is analyzed car data and tested ground pluse,and the cause of remote I/O module failure are summarized.Secondly,the communication anti-interference capability of remote I/O module under two different operating conditions are comparatively analyzed.Finally,the advantage of anti-jamming capability and reliability of remote I/O module are verified in optimization of ground mode.
