星载总线系统的测试方法研究
Research on Test Methods of Spaceborne Bus System
摘要
针对星载总线系统在应用中可能会遇到的故障问题,提出了一种针对1553B总线物理层 和协议层的测试方法。其中,物理层的电气特性测试包括电压、阻抗、波形和码元分析等;复杂的协议 层测试内容包括指令传输、地址识别、有效数据、校验位和消息间隔等。最后,通过实验验证了 这种测试方法的有效性和实用性。
Abstract
According to the failure problem which might be occurred in the application of a sapceborne bus system, a test method for the physical layer and protocol layer of a 1553B bus is proposed. In the method, the test of the electric characteristics of the physical layer includes the analysis of voltage, waveform, code, etc. The test of the complex protocol layer includes the analysis of instruction transmission, address recognition, effective data, check bit and message interval, etc. Finally, the validity and practical applicability of this test method are verified experimentally.
