磷化液温度WinCC监控系统设计

Design of phosphating liquid temperature system based on WinCC

磷化是汽车涂装的重要工艺,磷化液温度对形成良好的汽车漆面起到至关重要的作用。磷化液温度WinCC监控系统由WinCC监控画面、水槽装置和PLC控制器三部分组成,实现了磷化液温度的PT100测量、PID恒定控制和加热棒的工作占空比调节。该系统优化了硬件、软件的设计,进行了实验研究,不仅解决了远程实时控制的技术难点,还能脱离硬件设备进行仿真教学,具有实际应用与教学价值。

Phosphating is an important process in automobile coatings, phosphating solution temperature on the formation of a good car paint, play a crucial role. The system consisted of WinCC monitor, water-tank and PLC. The system has realized the measure- ment of PT100 ,temperature of solution temperature of solution of PID constant control, heating rod working duty cycle adjustment. This system not only greatly improves the automation level in the actual production line and realizes the remote control but also re- alizes the simulation teaching. This system has its own economy value, and it can save the teaching cost,it＇ s a typical combination of practical application and teaching case.
