基于规则的可编程1553B总线系统测试方法

Rule-Based Programmable Test Method for 1553B Bus System

从卫星测试需求出发，通过分析标准中规定的1553B总线信息传输形式及目前卫星常用的1553B总线通信协议涉及的各类信息，对特征进行提取归纳形成总线系统配置规则、总线消息流程标志配置规则及总线消息配置规则等，地面测试系统通过识别和学习卫星1553B总线系统规则的方法以实现卫星全测试过程的可编程1553B总线系统监视、总线通信模拟、数据存储及事后处理。经星地测试验证表明规则识别方法灵活有效，提高星地测试系统部署效率，当卫星1553B总线系统通信协议发生更改时能够简化星地测试系统维护流程，提高测试工作效率，符合卫星各阶段测试使用要求。

Considering the test requirements of a satellite, the transmission forms of 1553B bus information mentioned in the standard and the bus information frequently-used in communication protocols of satellite are analyzed, some features are abstracted to form the bus system, message process flags, and message configuration rules, the ground test system fulfilled the programmable monitoring, simulation, data storage and the post pro- cessing of bus system for all test phases by recognizing and learning the rules of 1553B bus system. This test method of 1553B bus system verified by satellite and ground test means that rule recognition is effective, it can improve the efficiency of satellite and ground testing, and once the protocol changes, the test procedure can be simplified, and the work efficiency is improved, which is suitable for all testing phases of satellites.
