QJ71E71-100恒壓供水系統硬件設計
本文中的自動恒壓供水控制系統的核心硬件是由PLC網絡（S0及S7-200由Profibus-DP構成PLC網絡）、人機界面（WINCC）、兩臺臺達VFD-F變頻器分別一對一拖動兩臺水泵電機（KQSN-500M9621）、壓力變送器、水池液位計等組成。人機界面接受操作人員輸入操作指令（如恒水壓指令等）和監控執行機構的運行情況；PLC為控制機構，進行數據傳輸及控制指令的發布；變頻器執行PID控制拖動水泵機組；壓力變送器監控管道壓力并向控制系統傳輸壓力信號（4-20mA電流）。水廠PID自動恒壓供水系統核心硬件構成圖如圖1所示。FANUC A06B-0345-B231 AC SERVO MOTOR 5F/3000
