    • Abstract
  • In view of shortcomings of complicated operating, inconvenient maintenance and incidental misoperation existed in mine auxiliary car operating control system based on single-chip microcomputer or integrated circuit, a design scheme of mine auxiliary shaft car operating control system based on PLC was proposed. Structure, control method, control process and core interlock relationships of the system were introduced. Wellhead and downhole work station of the system were separately installed a set of car operating PLC, and they use PLC to receive position signals and garage control signals to control running of car operating equipments. The practical operation showed that the performance of the system is stable and reliable, which ensures safety production of coal mine.
