Abstract: For coal bunker position detection and distribution warehouse vehicle operation control of practical problems, to design a set of a continuous detection of coal bunker coal precision automatic control system for the coal, the mathematical model is established for detecting mobile positioning process, the position information in relation to the distribution warehouse automation control car, can through the accessory installation of radar level meter charging position signal real-time adjust the car speed, the control process and positioning data together, in addition to the storehouse car positioning error and position error of the indicator problems are analyzed and processing, improve the system accuracy. The field operation of Zhaozhuang Coal preparation plant shows that the system can realize the coordination between the warehouse position monitoring and the automatic control of the warehouse trolley. The automatic operation and precise coal dropping of the trolley are good, and the position detection is accurate. Meanwhile, the number of sensors is reduced, the maintenance cost is reduced, and the manpower and material resources are saved.
