Design of Generalized Target Range TT&C System Based on Remote Dynamic Reconfiguration

摘要:

为方便设备的远程升级维护,提高测试效率,提出一种基于远程动态重构的通用靶场测控系统设计方案。通过PXI总线将试验所需的各模块集成于前端测控组合,由后端主控计算机完成对前端设备的综合调度,由数据处理计算机完成遥测数据的实时处理。利用可编程片上系统实现测控组合中部分模块的远程动态重构功能,使同一设备适应不同RS422通讯协议,适应调频、扩频等不同的测控体制。测试结果证明,系统可靠性高,模块重构时间短。该方案有效节约资源,具有广阔的应用前景。

Abstract:

In order to facilitate remote upgrade and maintenance of equipment, and improve the test efficiency, a method is present to design a generalized target range TT C system based on remote dynamic reconfiguration. Modules required are integrated in the front-end TT C unit equipment by PXI bus, and controlled by the back-end control computer. Telemetry data are processed by the back-end data processing computer in real time. The remote dynamic reconfiguration of some modules in the TT C unit equipment is realized on the System-on-a-Programmable-Chip, so that the same equipment could adapt to different RS422 communication protocols and adapt to the different TT C structures such as frequency modulation and spread spectrum modulation. The test result shows that the system has high reliability and the modules are reconfigured rapidly. This method is able to save resources effectively and has broad application prospects.
