摘　　要：轨旁安全平台是一种采用二乘二取二冗余架构的计算机平台,支持应用使用不同的外部协议接口,实现与不同的外部设备进行通信.本文基于轨旁安全平台的冗余架构和通信原理,针对平台支持的安全和非安全协议通信设计不同的场景进行测试,同时对平台的性能进行了测试,验证了轨旁安全平台的协议通信满足既定需求和实际应用场景.Trackside safety platform adopts a double 2-vote-2 redundant structure,which supports applications using different external protocol interface to realize the communication of different external peripherals.This paper is based on the redundant architecture and communication principle of the trackside safety platform.For the security and non-security protocol communication supported by the platform,we designed different scenarios to test them.And we also test the performance of the platform.Through these tests,we can verify that the protocol communication of trackside safety platform meets the established requirements and actual application scenarios,and it is safe and stable.
