[Abstract]:Mine hoist is often called the throat of mine. Its control level and reliability directly affect the daily production and safety of coal mining enterprises. At present, the control of hoist mostly adopts the traditional relay-rotor series resistance, which has seriously affected the requirement of continuous large output production in coal mining enterprises, and at the same time, the safety and reliability of coal mine is very low, and the accidents of personal injury and death occur frequently. Nowadays, the use of programmable controller and special motion controller to accurately control the speed and stroke of hoist has become an important development direction of hoist system. In this paper, the automatic control system of mine hoist based on FM458 module is studied. The main work is as follows: firstly, the research background and significance of current hoist system are introduced, including stroke control, safety and reliability, system monitoring, etc. The research status of hoist control system at home and abroad is compared, and the related characteristics are analyzed. Secondly, the paper introduces the working process of hoist and the requirements of coal mine enterprises for automatic control system, and analyzes the speed diagram curve of the current automatic control system of hoist. Aiming at the problems of comfort and system control disturbance in the existing models, a S-shape symmetric 7-order speed curve model is proposed, and the speed and position control algorithm is given, and the process system of the hoist is analyzed. Control system and supporting electrical transmission equipment are described. On this basis, the hardware and software design of the hoist automatic control system is given. The hardware part includes the module selection of the main control system and the motion control system, the field detection instrument, the configuration of the operation table and the upper computer. The software part includes the main program security monitoring system and the function design of motion control system module. According to the specific function module, the corresponding program flow chart and function diagram are given. Based on WinCC Flexible software and STEP 7 programming software, the implementation of the system is given. Finally, the S-shape symmetric 7 th order velocity curve is simulated based on PLC-ANALYZER software. The system test results show that the automatic control system can fully meet the overall task requirements of coal mining enterprises, high ride comfort, control accuracy to meet the error requirements. The automatic control system of coal mine hoist has been successfully used in a large state-owned coal mine in Shanxi Province, which was formally put into operation in February 2015. The successful development of the system greatly improves the production capacity of the coal mine enterprise and effectively avoids the occurrence of safety accidents. The design method of this subject can also be applied to other mine engineering such as gold mine and copper mine hoist system design.
