为了满足控制设备测试、维修和训练对测试设备的需求,设计了分布式装备测试与训练系统。对分布式合成仪器检测仪的结构及工作流程进行了详细地阐述。设计了以FPGA为核心的主控模块,以单片机为核心的通道选择、信号调理、激励信号产生等受控模块。经过系统的运行试验,表明系统运行稳定,系统设计合理、可行。 In order to meet the needs of control equipment testing, maintenance and training on test equipment, a distributed equipment testing and training system was designed. The structure and working flow of distributed composite instrument detector are described in detail. The main control module with FPGA as the core, the channel selection with the singlechip as the core, the signal conditioning and the stimulus signal are designed. After the system operation test, it shows that the system is stable and the system design is reasonable and feasible.
