煤矿井下胶带机PLC控制系统的设计
摘要
可编程逻辑控制器（Programmable Logic Controller），简称PLC。PLC 控制技术已广泛应用于自动化控制的各个领域，本文详细介绍了一种煤矿井下胶带机的PLC自动监控系统。该系统利用欧姆龙CJ1M型PLC控制核心，可与多种智能电子设备进行通信，实现了煤矿胶带机系统的自动监控。方案容易实现，可靠性高。对相近系统有重要的参考价值，能实现各胶带机胶带的高低速度、滚筒温度、机头烟雾、CO浓度、堆煤以及跑偏等各种保护功能，还兼有与前后胶带机智能综保仪通信的功能，使整个系统具有逆煤流启动、顺煤流延时停车功能，基于该方案的控制系统与原系统相比在性能和自动化程度上都得到大幅度提升。
胶带运输机作为一种主要的连续运输设备,广泛应用于煤矿行业。其特点是物料能被连续运输,且生产效率高、结构简单、动力消耗少以及便于组成流水生产线,使企业生产过程实现机械化、连续化及自动化。煤矿胶带机集控系统运行安全可靠与否直接影响矿井的经济效益。为提高胶带机运输系统的可靠性和安全性，实施集中监控和实现系统的综合保护，是十分必要的。
采用PLC和多种智能设备对煤矿胶带机进行有效控制是十分必要的，不仅在安全、速度、运量及多种因素上起着重要作用，而且可以更高的实现工业的自动化与广泛应用。

Adhesive Tape Machine of Coal Miner PLC Cont
System Design Abstract
The PLC control technology has widely applied in automated control each domain, this article introduced one kind of coal mine shaft adhesive tape's machine PLC automatic monitoring system in detail. This system use ohm dragon CJ1M the PLC control core, may carry on the correspondence with many kinds of intelligence electronic installation, has realized the coal mine adhesive tape machine system's automatic monitoring. The plan easy to realize, the reliability is high. Has the important reference value to the close system, can realize various adhesive tapes machine adhesive tape's height speed, the drum temperature, the nose smog, the CO density, a pile of coal as well as runs and so on each kind of protection function, but also has at the same time quick-wittedly with the around adhesive tape can the synthesis guarantee the meter correspondence the function, enables the overall system to have the counter coal class to start, along the coal class time delay parking function, compares based on this plan's con.
The adhesive tape transports machine as a kind of main continuous conveyer, extensively is applied to coal mine craft.Its characteristics is a supplies energy drive continuous carriage, and production efficiency higher -, simple structure, the power consume little and easy to composition flowing water production line, make business procedure in production realize mechanization, turn and automate in a row.Whether coal mine adhesive tape machine gathers to control system run - time safety firm or not directly effect the economic benefit of ore well.In order to raise the reliability and stability of adhesive tape machine transit system, the implementation concentrates supervision and carries out the synthesis safeguard of system, is very necessary. Uses PLC and many kinds of intelligent equipment carries on the active control to the coal mine adhesive tape machine is very essential, not only in the security, the speed, the transportation amount and many kinds of factors is playing the influential
