At present,the general method to prevent such failures is to use dual redundant configuration to avoid the global impact due to the failure of one bus,but this cannot fundamentally avoid the occurrence of failures,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。
