At present,the general method to prevent such failures is to use dual-channel redundant configuration to avoid the global impact due to the failure of one bus,but this cannot fundamentally prevent the failure,and once a bus fails,processing It is very easy to cause another bus failure,and the consequences are very serious.An effective method should be to prevent poor bus contact or open circuit.

目前，一般防止此类故障的方法是采用双路冗余配置的方式，避免因一路总线发生故障而影响全局，但这并不能从根本上避免故障的发生，并且一旦一根总线发生故障，处理时极易造成另一个总线故障，其后果是非常严重的。有效的方法应是从防止总线接触不良或开路入手。
