摘要
卫星遥测信号解析是卫星综合测试系统的重要组成部分;传统的遥测信号采集方案,基于Windows非实时平台,降低了系统解析的实时性和和判读的有效性;从故障预案的模型系统应用场景为出发点,阐述了基于实时系统模型架构的遥测信号仿真模型设计思路、原理及功能实现;该方法继承了模型的迭代特性,通过在每一个周期中对比特流数据的读取和同步帧头的识别,实时地获取遥测信息,为设计故障预案,提供充分信息,具有较强的工程实际意义。
Satellite telemetry signal resolution is an important part of satellite integrated test system.The traditional telemetry signal acquisition scheme is based on the Windows non real-time platform,which reduces the real-time resolution and the effectiveness of the interpretation.The design idea,principle and function realization of the telemetry signal simulation model based on real time system model architecture are expounded from the point of view of the application scene of the model system of the fault plan. This method inherits the iterative characteristics of the model,and obtains the telemetry information in real time by comparing the reading of the special flow data and the recognition of the synchronous frame head in each cycle.It provides sufficient information for the design of the fault plan,and has a strong practical significance.
