基于PLC和触摸屏的液体配料控制系统设计
摘 要：本组课题是对液体自动混合装置的模拟控制，实现液体混合装置的自动添加液体、自动混合等自动控制功能。在PLC程序设计的基础上结合有关的外围设备形成一个易于工业控制的系统整体，在易于扩展其功能的原则而设计。本监控系统采用PLC为控制核心，具备自动混合两种液体的功能，由传感器检测储藏罐中的液面高度，按顺序加入A和B两种液体，搅拌后放出混合液体。过程监控上，我们采用的是MCGS组态软件，这是我国自主研发的组态软件，适用于各品牌的PLC。最后将PLC中的程序同步到MCGS中，进行仿真调试，实现界面的实时监控。

Liquid ingredients PLC and HMI control system based on
Abstract: the subject is simulated control of automatic liquid mixing device, automatic adding liquid, automatic mixing and other automatic control functions to achieve liquid mixing device. Combined with related peripherals in PLC program design based on the formation of an easy to industrial control systems in general, easy to expand its function the principle design. The monitoring system uses PLC as the control core, with automatic mixing two liquids, liquid level sensor for the detection of the storage tank in order to join A and B, two kinds of liquid, liquid mixture stirring after release. Process monitoring, we use the MCGS configuration software, this is our independent research and development of configuration software, suitable for all brand PLC. Finally, the procedure in the PLC synchronization in MCGS, simulation debugging, real-time monitoring of the implementation of the interface.
Keywords: automatic liquid mixture, the programmable controller PLC, MCGS configuration software
