矿井提升机是矿山当中非常重要的设备,它担负着矿石、物料、人员运输的责任。过去的矿井提升机控制系统采用的是继电器———接触器来进行控制,这种提升机在一般情况下是采用电动机、转子回路来串接附加到电阻,然后再进行启动、调速,所以这种控制系统的可靠性非常差,而且不易操作,故障率非常高,很容易造成电能的浪费。随着科学技术的不断发展,矿井提升控制系统成了现代矿井专家研究的主要的对象,现针对提升机控制系统所存在的问题,提出PLC控制器在矿井提升机中应用的重要性。
Mine hoist is a very important mine equipment, it is responsible for the ore, materials, personnel transport responsibilities. Past mine hoist control system uses a relay --- contactor to control, this hoist in the general case is to use the motor, the rotor loop to the series connected to the resistance, and then start, speed, so The reliability of this control system is very poor, and not easy to operate, the failure rate is very high, it is likely to result in a waste of energy. With the continuous development of science and technology, the mine hoist control system has become the main object of modern mine experts research. In view of the problems existing in hoist control system, the importance of PLC controller in mine hoist is put forward.
