摘要
针对导弹自动驾驶仪性能特点，设计了导弹自动驾驶仪测试系统软件。详细叙述了自动驾驶仪测试系统软件的设计方案，重点分析了RS-485总线冲突的解决方案和基于Modbus协议数据包的解读机制。实时测试软件采用模块化设计思想，实现了测试的自动化和综合化。应用表明，该测试软件操作简便．运行稳定可靠。
The test system software is developed for missile autopilot. The solution to RS-485 bus conflicts and the data package identification and process was analyzed based on the Modbus protocol. The design of the real time test software is presented, which considers the communication reliability. The software can test automatically and synthetically by using different modules. The application results show that the software is steady, reliable, easy to use.
