摘要
 隨著我國經(jīng)濟(jì)的高速發(fā)展，城市化進(jìn)程的加速和人民生活水平的不斷提高，人們對(duì)供水的質(zhì)量要求也越來越高，也更加重視降低供水系統(tǒng)的成本。在水廠改造中采用新工藝、新設(shè)備和更為先進(jìn)、可靠、高效的控制手段已成為必然趨勢(shì)。而PLC以其可靠性高、抗干擾能力強(qiáng)，系統(tǒng)配置靈活、編程容易，調(diào)試、維護(hù)簡(jiǎn)單等優(yōu)點(diǎn)，使得它在水處理自動(dòng)控制中得到廣泛應(yīng)用。本次畢業(yè)設(shè)計(jì)主要研究了施耐德Premium系列PLC在水廠自動(dòng)控制系統(tǒng)的應(yīng)用，并簡(jiǎn)要分析了Modbus TCP/IP通信，并介紹工作原理。本文介紹了水廠的各站點(diǎn)的工藝流程，并根據(jù)水廠的實(shí)際情況，分析了PID控制算法及改良的PID控制算法，并使用該算法實(shí)現(xiàn)對(duì)各個(gè)站點(diǎn)的自動(dòng)控制。使用Intouch 10.0軟件，開發(fā)了上位機(jī)控制系統(tǒng)。

Abstract
 With the rapid development of our country’s economy, the accelerated urbanization process and the continuous improvement of people's living standards, the quality of water is getting higher and higher, so we should pay more attention to reduce the cost of water supply systems. Water plant used in the transformation of new techniques, new equipment and more advanced, reliable and efficient means of control has become an inevitable trend. And the PLC for its high reliability, anti-jamming ability, and system configuration flexibility, easy programming, commissioning, maintenance and simple, making it in the water treatment is widely used in automatic control. The design of the graduate research of Schneider Premium Series PLC automatic control system in the application of water works and a brief analysis of the Modbus TCP / IP communications, and describe the working principle. We have introduced the process of water plants, and analyze the PID control algorithm and the improved PID control algorithm based on the actual situation of water plants, and the use of the algorithm to achieve automatic control for each site. We use the Intouch 10.0 software to develop a PC control system.
