|
摘要
为满足某型姿轨控动力系统热试车需求,研制了一种基于DSP+FPGA的姿轨控发动机控制监测系统。采用模块化设计,主处理器采用DSP指令及数据分析,各功能模块采用FPGA进行PCI总线管理和模块功能实现,各功能模块独立工作、自主采集或程序发控。通过分立式多核心并行处理架构的软件方案,综合运用手动、时序和自动发控方式,实现了54路阀门控制及64路信号同步采集、实时分析存储。该系统已多次用于全系统热试车及总装测试,满足总体要求,性能稳定可靠,操作使用方便,有效降低了姿轨控动力系统试验成本,具有较高的实用性和推广价值。
To meet the test requirements of an orbit and attitude control propulsion system, a control monitoring system based on DSP and FPGA is developed. The system adopts modular functional design, DSP is adopted as the main processor for instruction and data analysis, FPGA is adopted as the PCI bus management and module function realization,each functional module works independently, collects independently or processes control. Through the software architecture scheme of discrete multi-core parallel processing, and by using manual, sequential and automatic control modes, it realizes 54-way electromagnetic control, 64-way signal synchronous acquisition, real-time analysis and storage.The system has been used in the thermal test and assembly test for many times. It meets the overall requirements, has stable and reliable performance, is easy to operate and use, effectively reduces the test cost of attitude-orbit control engine, and has high practicability and popularization value.
