摘要当今社会矿井提升机在煤矿企业的生存上起着决定作用，是关键所在，所有矿石原料，物料和人员的运输都在于它，矿井提升机的运行安全与效率对其整个企业的经济效益起着直接的联系。另外，对于现在的资源利用，只能在加深矿井的开采深度，所以对要求更加高的矿井提升机，它的应急措施和生产的效率就要更高，然而，现在的矿井提升机安全系数很低，而且故障率高，满足不了生产效率和安全措施，所以对矿井提升机的技术改造是势在必行的措施。73713

 在矿井提升机电控系统方面设计器件使用的是PLC，改善调速系统也是本次关键环节，使用的是变频器来实现的。本文的设计是根据提升机的具体要求来设计的，包括硬软件设计。在整个运行中有控制环节，保护环节，是通过监视用继电器配合使用实现的。 

 经过具体运行，与传统系统相比可靠性和安全性显著提高，控制方面使用g更灵活，并且节能经济，使得矿井提升系统的自动化水平得到显著提高。

Design of Control System on Mine Hoist  Based on PLC

Abstract Mine hoist in today's society plays a decisive role on the coal mine enterprise's survival, it is the key to all mineral raw materials,materials and personnel transport depend on it, the operation of the mine hoist safety and efficiency of the whole enterprise economic efficiency play a direct link。 In addition, for the resource utilization, we can only deepen mine mining depth,so the more demanding of mine hoist, its emergency measures and production efficiency will be higher。However,  mine hoist’s safety coefficient is low right now, and the failure rate is high, it can't satisfy the production efficiency and safety measures, so the technological transformation of mine hoist is imperative measures。

The use of device in the electrical control system is PLC。 Improving the speed control system is the key link。Use of frequency converter to realize it。The design is according to the concrete requirements of mine hoist to be designed,including hard and software design。Control links and protection link in the entire operation are used by monitoring to relay。

Running results show that the system is higher reliability, higher security, more flexible control,more energy and money saving than the traditional control system,The automation level of mine hoisting system is improved significantly。
