摘　　要：分析了基于多协议接口的HXD1型电力机车制动状态监测系统,采用存储器总线时分复用的方法,解决了多协议兼容共享通信存储器造成冲突访问的问题。通过建立多通信接口共访存储器冲突模型,对通信接口的时间相位偏移参数进行评估,得到最小访问冲突下的时分复用参数。This paper analysed brake condition monitoring system based on multi-protocol interface of HXDI electric locomotive and solved the access conflicts problem caused by multi-protocol compatible communications shared memory by using time division multiplexing method with the memory bus. The TDM parameters under the minimum access violation were obtained by establishing multi-access memory conflict model through communication interface and evaluating the phase shift time parameter of the communication interface.
