摘　　要：结合旋转机械远程采集诊断技术,系统地介绍了采用TMS320C25进行数据采集与处理,并通过单片机与通用异步收发器16450接口和控制智能MODEM以实现频谱分析仪与远程PC机在有线公共电话网中进行远程数据通信的技术。The telecommunication of the spectrograph analytic instrument based on DSP was studied, and how to use TMS320C25 to acquire and process signals was briefly introduced. In the testing system, the intelligent MODEM and 16450 chip were controlled by 89C51 for remoting data communication between the spectrograph analytic intrument and the PC in a long distance through PSTN.
