摘　　要： PC机-单片机组成的分布式智能测控系统在现代测控系统中占据着重要地位。基于VB语言及串口通信技术,本文以STC12C5A60S2单片机-PC机为核心建立了一套设备温箱测控系统,通过上位计算机与串行口的通信完成对底层控制器的多种操作,实现了PID恒温控制、对温度数据的实时采集、存储、动态图形显示、历史数据查询、历史曲线显示等功能,用于满足对温箱的各项测控要求。该温度测控系统实时性好,电路简单,扩展功能强,具有一定的推广应用价值。 Distributed intelligence measurement and control system consisted of personal computer and single chip microcomputer （SCM） plays an important role in modern measurement and control system. A set of device thermotank measurement and control system based on STC12C5A60S2 SCM and personal computer was developed in this paper based on VB language and computer serial port com- munication technology. Several requirements of device controller were met by communication of host computer with serial port. Many functions such as PID thermostatical control, temperature data real time picking, storage, displaying in dynamic graphic, inquiring and curving of historical data were fulfilled in order to meet the thermotank measurement and control requirements. The system characterized by good real - time performance, simple circuit and powerful expansibility which owned a great application value and good market pros- pects.
