摘　　要：用单片机模拟智能仪器,实现了微机RS232到单片机串行口的电平转换及电气连接,为单片机系统设计了终端服务程序,微机上采用Windows环境自带的超级终端对其操作。主要介绍了单片机中终端服务菜单程序、通信程序的编写,电平转换电路的实现方法,实现了通过超级终端控制智能仪器的运行并读取单片机系统的相关信息。The study is to simulate intelligent device with microprocessor and successfully carry out the connection and conversion between RS232 and TTL in the format of level conversion. An executible terminal service program which is to be run in microprocessor systems is designed to connect PC and microprocessor systems. It provides menu procedures, communication programming, methodology of level conversion. Through the control of microprocessor, the information is retrieved from PC successfully.
