【摘要】我国矿井提升绞车大多是采用交流异步电机拖动，其电气控制系统采用转子串、切电阻调速，由继电器－接触器构成逻辑控制装置。本文以安全、可靠、高效、经济为出发点，以可靠性原则为依据，对矿井交流提升绞车电控系统中转子电路串电阻调速部分，进行研究设计，由可编程控制器（PLC）代替继电器－接触器构成的逻辑控制装置。本文以JTK-1.6X1.2矿用提升绞车为例，提出了研究设计方案，结合实际情况，对实际现场应用的提升绞车进行改造，研究探讨提升绞车电控系统的改进与优化设计。PLC电控系统实现了对提升过程的程序控制，精度高；实现了速度、电流以及矢量的数字交换等，对提升绞车进行闭环调节；实现行程、速度等重要参数及提升状态的监视实现无触点控制，寿命长，可靠性大大提高；具有良好的控制监视系统。

Abstract: China's mines are hoist AC Induction Motor Drive,and its electrical control system uses a rotor series, cutting speed resistance ,by the relay - contactor control devices constitute a logical. In this paper, a safe, reliable, efficient and economic as the starting point, reliability based on the principle of exchange of mine hoist control system of electric circuit series resistance of the rotor speed control part, runs research design, by the programmable logic controller (PLC) to replace the relay - contactor control devices consisting of logic. In this paper, JTK-1.6X1.2 mine hoist for example, a research and design programs, combined with the actual situation of the actual field application of hoist modify study to enhance the improvement of mechanical and electrical control system design and optimization. PLC electrical control system to enhance the process of realization of the process control, high precision; to achieve speed, current as well as the vector, such as digital switching, the closed-loop regulation of hoist carried out; the realization of stroke, speed and other important parameters and to enhance the status of realization of a touch monitor control, long life, reliability, greatly increased; has a good monitoring system to control..
