摘要
参照小区恒压供水项目工艺条件和控制需求,开发了恒压供水自动控制实验系统,设计了变频一拖二控制电路,编制了压力定值PID控制程序、水泵无扰切换控制程序和限值及连锁保护程序.实验系统结构简单、使用方便、可移植性强,适用于高校电气、自动化等电类专业学生课内、外自动化控制工程类课程教学与实验实训,并在实际教学应用中取得良好的使用效果.
Based on the process conditions and control requirements of the constant pressure water supply system,the automatic control system of the constant pressure water supply was developed.The control circuit of variable frequency one for two was designed,and the constant pressure value PID control program,the water pump non-disturbance switching control program and the limit value and interlock protection program were compiled.The experimental system has simple structure,easy to use and strong portability.It is suitable for teaching and experimental training in the course of electrical and automation engineering in and out of class of universities,and has achieved good results in practical teaching and application.
