航电系统是现代战机的重要组成部分,构建一个1553B机载总线通用仿真测试系统可以实现对特定航电设备的测试及故障定位,并为航电设备的开发提供一个调试平台。重点分析了系统逻辑结构、层次式软件结构及系统的应用程序框架,介绍了系统测试资源层的组件结构及各组件的功能,并对系统的实现作了简要说明。该系统已应用于对特定航电设备的测试,效果令人满意。
The avionics system is an important part of modern fighter aircraft. The construction of a 1553B on-board bus simulation system can test and locate the avionics equipment and provide a debugging platform for the development of avionics equipment. The system logical structure, the hierarchical software structure and the system application framework are analyzed emphatically. The component structure of the system testing resource layer and the functions of each component are introduced. The system implementation is briefly described. The system has been applied to the testing of specific avionics, the effect is satisfactory.
