Study on Network-Based Comprehensive Testing of a New Avionic UMS

针对新型机载机电管理系统功能性能测试需求,提出一种基于EtherCAT总线的网络化测试系统设计方案。该系统的设计采用模块化的设计思想,分别设计嵌入式主站、功能从站,主站与从站间通过EtherCAT总线实现数据通信。该系统具备仿真飞机机电子系统设备的各类输入输出信号与模拟飞管系统总线通信活动功能,可以实现对新型机载机电管理系统功能与性能的验证。测试结果表明,该系统测试覆盖率与测试效率高,运行稳定,可扩展性强。

According to the requirements for function and performance testing of new avionic utility manage- ment system, a design scheme of a network-based automatic testing system based on EtherCAT is proposed. Based on modular design concept, this system, consists of embedded master node and functional slave nodes, and the communication between them is realized by EtherCAT. This system can simulate any I/O signal of air- borne eleetromechanieal equipments, emulate the bus communication of flight control system and implement the function and performance testing of new avionic UMS. The results show that the system has high testing cover- age ratio and efficiency, and its stability and extensibility are outstanding.
