摘　　要：针对地铁制动实验台8路400Hz^1000Hz的PWM信号,设计出基于MSP430F449的系统,进行信号采集、转换和处理,并通过USB接口上传给上位机;同时能接收上位机下达的命令输出所要求的PWM信号。经测试,系统能满足多路信号采集转换的实时性和高速性的要求,工作稳定、可靠。A system for processing eight routes of PWM signals ranging form 400Hz to 1KHz was developed for the underground railway braking testing platform. The system was based on the MSP430F449 CPU that could convert the received signals and send them to the PC. Meanwhile, the system could accept the signals from the PC and output the corresponding PWM. According to the test result, the system can meet the requirements of high speed and real time processing and reliably.
