摘　　要：在某型自动测试设备上,针对多路电源供电控制及其电路监测的实际功能需求,设计了基于DSP的电源监控单元;以DSP芯片为采集控制单元,采用主板、子板分层式结构,设计了RS422通信接口等电路;测试软件采用汇编语言和C语言混合编写,并为串行通信设置了编码校验机制;实验结果表明,该设计监测精度高,开关控制准确,解决了工程应用需求,满足实时性、可靠性指标。On the automatic test equipment, according to the function demand for multicenter power control and the electrical test, a power controller unit was designed based on the DSP chip. Using a DSP chip as the collection and control unit, the hardware was designed by layered structure. And a communication circuit based on RS422 was designed. The software was compiled in both assemble language and C programming language, and a check mechanism was set for the code. It can be indicated from the experiment that the design has a good test precision, and it controls the switches correctly. Above all, the design solved the problem of engineering application, and the demand of real time and reliability can be completely met.
