Abstract

The invention discloses a frequency converter winch system based on a PLC and a control method thereof and relates to the technical field of coal mines. The problem of low safety in the prior art is solved. According to the system, a control table controls operation of a motor through a frequency converter; the motor controls operation of a winch; a tensile device is arranged at one end of a mine car and is connected with the winch through a rope; a tensile sensor is arranged in the tensile device; a processor and a zigbee module are arranged on the mine car; a plurality of repeaters, a plurality of voice alarms, a plurality of acousto-optic signal devices and a plurality of handsets are evenly arranged in a mine coal roadway; and the control table is sequentially connected with the multiple repeaters, the multiple voice alarms and the multiple acousto-optic signal devices through leaking cables.

Description

Technical field [0001] The invention relates to the technical field of coal mines, and more specifically to a PLC-based frequency converter winch system and a control method thereof. Background technique [0002] With people's requirements for energy conservation and environmental protection in recent years, frequency converters have been widely used in coal mines, mainly embodied in the application of stepless speed regulation such as compressors, ventilators, hoisting equipment, winches, and belt conveyors. The use of frequency converters can reduce power line voltage fluctuations, reduce impact on the grid, and has adjustable acceleration functions, operating speed and torque poles, controlled stop methods, controllable motor starting currents, reversible operation control, and reduction of coal mining machinery The wear and tear of equipment can effectively reduce costs and improve system stability. Application in hoisting equipment and winches can not only reduce the pullin...
