矿井钢缆皮带效率最优网络控制系统研究

Study on Optimum Network Control System of Mine Cable Conveyor Belt Efficiency

该文针对钢缆皮带主运系统在实际应用中的现状及存在的问题,结合近几年流行起来的工业网络技术,开发了一套基于以太网的钢缆皮带网络控制系统,对整个系统进行了效率最优控制,并解决了网络延时对控制效果的影响。由于钢缆皮带电控系统存在最佳负载,文中通过PLC计算其在不同速度下的最佳负载点,从而确定给煤机的速度,并通过网络控制系统对给煤机速度进行控制。由于网络中存在延时,笔者通过网络化模糊控制器解决了网络延时问题,实现了快速、准确的给煤控制,实现了整个系统的效率最优化。

In order to solve the problems of the transport system,this paper develops a network control system with Ethernet based onthe industrial network technology.This paper also designs an efficiency optimization strategy for the system,and solves the problemof network-induced delay.The wire rope strap electrical control system has an optimal load point.According to the wire rope straps’speed,this paper calculates the optimal load point with PLC,and calculates the speed of loading machines.It controls the speed ofloading machines by network control system.Because this system has network-induced delay,this paper solutes this problem by networkfuzzy control.This system realizes the quickly and nicety speed control,and realizes the efficiency optimization of the main transportsystem.
