The control system of the traditional coal mine hoist mainly adopts relay contactor for control, and the hoist usually starts and adjust the extra resistance in the rotor circuit of the motor.. The control system has the disadvantages of poor reliability, plex operation, high failure rate, waste of power and low efficiency.. Therefore, it has practical significance to study the control system of the mine hoist, and is also a research subject of domestic and foreign experts and scholars.. The in the view of the elevator control system in the presence of the above problems, the programmable program controller and a frequency converter used in elevator control system, and have carried on deeper research in feasibilityThe control of the hoist is essentially a position control, to ensure that the lifting container is located in the reservation location, the accuracy is high, and the current can reach to the 2cm. shaft, a cylinder and a wire rope wear signal processing calculated container accurate position and impose control and protection. General process control with microputer for monitoring, stroke control is alsoAt present, the AC winding motor relay contactor system, which is the most of the electromechanical control system, is controlled by the series resistance of the rotor loop. The equipment is obsolete and the technology is backward.. And there are m
