摘　　要：TTP总线技术是面向机载分布式安全关键系统的主要总线技术之一。针对TTP总线数据的实时监控和分析需求,提出了面向总线消息且不依赖于特定总线配置的异步总线监控方法,给出了TTP总线监控节点及监控软件设计,达到了对时间触发通信总线数据的实时监控效果。构建验证环境开展了总线监控的测试工作,结果表明,监控节点能够实现对最高5 Mb/s速率数据的实时监控分析,能够有效支撑对TTP总线系统的数据的分析验证。Time-Triggered Protocol(TTP)is one of the key network technologies for the future distributed safety-critical airborne systems.For the requirement of real-time monitoring and analysis of TTP bus data,this paper proposed a message-oriented asynchronous monitoring method that is independent of specific configuration,and designed the TTP monitoring node and monitoring software based on the given methods and architecture,which can achieve the effect of real-time monitoring of TTP bus data.It also built verification environment to test bus monitoring function,the test results show that the monitoring node and software can realize the real-time monitoring and analysis of the data with a maximum rate of 5 Mb/s,and can effectively support the analysis and verification of TTP system message.
