基于PLC的选矿厂供水泵站控制系统设计
|
摘要
针对国内某大型选矿厂供水系统自动化水平低、能耗高的问题。利用变频器、真空射流泵、离心泵、电动闸阀等外围设备的联动调节,设计了一套吸入式供水系统。该系统基于SIMATIC S7-1200可编程控制器和TIA portal全集成自动化软件来进行设计,利用工业以太网的快速传输实现上下位机的数据交互,PID控制算法的使用实现了系统的逻辑闭环。系统测试结果表明,该系统的使用能有效地节约能源、降低运行成本。
Aiming at the problem of low level of automation and high energy consumption for the water supply system of a large-scale concentrator in China. A set of suction water supply system was designed by using the linkage adjustment of peripheral equipment such as frequency converter,vacuum jet pump,centrifugal pump and electric gate valve. The system was designed based on SIMATIC S7-1200 programmable controller and TIA portal fully integrated automation software. It used the fast transmission of industrial Ethernet to realize the data interaction between the upper and lower machines. The use of PID control algorithm realized the logic closed loop of the system. System test results showed that the use of this system could effectively save energy and reduce operating costs.
