【摘要】：随着科学技术水平持续发展,工矿企业采用先进的自动化设备是提高企业经济及安全效益的重要方法和措施。老式的带式输送机控制系统采用的是继电器控制,但是体积大、故障多并且反应速度比较迟钝,正逐渐淘汰而被新的控制系统所取代。PLC组成的控制系统其内部的触点及继电器可以多次被使用,反应快,并且构造简单、体积小、故障少,这种控制系统将逐渐代替传统的控制方式而广泛采用。本设计以冀中能源峰峰集团大淑村矿井下主运带式输送机原煤运输系统技术改造项目为依据,进行煤矿井下主运带式输送机的PLC集散控制技术设计,主要设计了九部带式输送机的PLC集散控制系统。通过整理各部带式输送机的基础资料,认真分析其运行现状,最后制定了带式输送机对PLC控制系统的控制要求,并且确定了每部带式输送机的保护功能。设计PLC集散控制系统时充分考虑了煤矿安全生产过程的特点,实现了系统的集中管理、分散控制,增强了PLC的控制能力,更加提高了安全生产的综合自动化水平。
[Abstract]:With the continuous development of science and technology, the adoption of advanced automation equipment in industrial and mining enterprises is an important method and measure to improve the economic and safety benefits of enterprises. The internal contacts and relays of the control system, which is being phased out and replaced by a new control system. PLC, can be used many times, react quickly, and are simple in structure, small in size, and less in failure. This control system will gradually replace the traditional control mode and be widely used. This design is based on the technical transformation project of the raw coal transportation system of the main transport belt conveyor in Dashucun Mine of Fengfeng Group in Jizhong. The PLC distributed control system of the main belt conveyor in coal mine is designed. The PLC distributed control system of nine belt conveyors is designed. Through sorting out the basic data of the belt conveyors, the present operation situation of the belt conveyors is analyzed. Finally, the control requirements of belt conveyor to PLC control system are formulated, and the protective function of each belt conveyor is determined. The characteristics of coal mine safety production process are fully considered in the design of PLC distributed control system. The centralized management and decentralized control of the system are realized, the control ability of PLC is enhanced, and the comprehensive automation level of safe production is improved.
