[Abstract]PLC is also referred to as programmable logic controller. It uses a type of programmable memory to store programs in its internal storage to perform user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and pass digital Or analog input/output control various types of machinery or production processes. With the continuous development of this technology, and close cooperation with DC speed control or AC frequency conversion speed control, different combination applications are used, and the logic operation, sequence control, timing, counting and arithmetic operation functions of PLC are used to control The control effect of the hoist is significantly improved, so that the mine hoist has superior control performance. Based on the improvement of the level of science and technology in my country, mine hoists in our country are increasingly developing in the direction of large-scale equipment, greater depth and speed, and high degree of automation and informatization of the control system. In order to improve the safety of the hoist, the programmable logic controller technology And significantly improve the reliability and safety of the hoist. Solve the problem that the traditional mine hoist is not reliable enough, improve the electricity consumption rate, reduce the failure rate, and effectively improve the intrinsic safety and transportation efficiency of the mine, thereby increasing economic benefits.
