Design and Development of PLC-Based Reverse Osmosis Seawater Desalination Control System
Aiming at the characteristics of reverse osmosis seawater desalination system with complex process,cumbersome operation and maintenance,and high requirements for professional skills of operators,a set of reverse osmosis seawater desalination control system has been developed.The whole process system in the pretreatment,reverse osmosis and other key process principles and automatic control process is studed in detial.From the system of hardware design and software development of two aspects of a detailed description.In terms of hardware,the selection of control system equipment is completed according to the size of the device and control requirements.In terms of software development,the development of several sets of software for controller and human-machine interaction interface has been completed.The system is successfully applied in the teaching practice class of reverse osmosis seawater desalination in colleges.The results of the application show that the system is reasonably designed,the operation interface is simple and convenient,and it can realize the purposes of teaching and training,troubleshooting and so on at the same time of stable and safe operation.While improving the professional skills of seawater desalination operators,the system also provides reference and technical support for the practical training courses of other majors in colleges.
