遥测实时系统深层设计缺陷分析与测试

遥测实时监控系统在飞行试验中的特殊作用决定了系统必须保持为零故障状态.为研究系统偶然出现的异常,首先对系统进行了实时跟踪,并实际捕获了各种具体现象.在此基础上,针对性地对相关电路、信号、遥测记录数据以及系统内核技术进行了测试、分析.最后指出系统底层某硬件模板存在时序及配置数据设计不够合理的问题,受到外方公司尊重并予无偿修改.结合分析、测试与二次消化,对目前国内尚未普遍使用的数字位同步器技术进行了初步解析.

Deep design defect analysis and test of an imported Real-time telemetry system

The special role of real-time telemetry system in flight test determines that the system must have no failure.To consider the occasional abnormalities in the system,we firstly tracked in real time the system and captured various phenomena.On the basis of this,we test and analyze relevant circuits,signals telemetry recording data and system kernel technology.Finally,we point out that a hardware template at the bottom of the system has time sequence and improper configuration data design problems,and the foreign company accepts our opinions with great respect and modifies them free of charge.With combination of analysis,test and second digestion,we give a preliminary analysis for digital bit synchronization technology which is not widely used yet in our country.
