摘　　要：镀液蒸发器是薄板镀锡生产线上利用真空下水蒸发的方法维持锡液浓度稳定的关键设备。为保证水蒸发的顺利进行 ,蒸发器液位需进行有效控制。为此 ,本文设计了测控系统 ,由基于 PC(PC- BASED)控制构成 ,并采用了带调整因子的模糊控制算法。现场运行表明 :本系统组态容易 ,编程方便 ,控制鲁棒性好 ,控制精度高 (在不采用积分控制的情况下液位误差小于1% ) ,容错能力强 ,具有广泛的应用前景。Plating solution evaporator is the key equipment of tinplate production line. In order to maintain the normal process flow, liquid level in evaporator has to be controlled. In this paper, PC Based measurement and control system is implemented and fuzzy controller with self tuning factor is designed. Through experiments, some conclusions can be drawn:this system is easer to configure and convenient to program. Fuzzy controller has excellent robustness and higher precision(liquid level error less than 1% without integral control). PC Based control has good development prospect.
