摘要
介绍了基于PC机的自动恒压供水系统。该系统根据供水管网的水压、水位、流量等参数,调整水泵的投入台数及转速,实现全自动恒压供水。给出了恒压供水系统的硬件组成框图及工作原理,根据系统功能要求,重点介绍了PC机与MCS-51单片机的串行通信原理。用VB语言设计了系统的上、下位机之间的数据通信、过程控制的显示和数据处理等程序。本控制系统具有工作稳定、人机界面好、系统扩展能力强和操作简便等特点。
Deals with an automatic constant-pressure water-supply system,which functions by means ofadjustment of the number and rotational speed of operating pumps in the light of such parameters as hydraulicpressure,water level and flow of the water-supply pipe-net.The hardware composition diagram of thesystem and its working principle are firstly presented,and on the basis of the functional requirement of thesystem itself,serial communication principle of PC computers and MCS-51 single chip microprocessor isfocused on.Language VB6.0 is adopted to design the programs for data communication between the upper andlower computers,display of process control and data processing.The system is characterized by stability,convenience,excellent human-computer interface and strong capability of expedition.
