摘要: 针对选煤厂煤仓仓位检测及配仓小车运行控制的现实问题,设计了一套煤位连续检测的煤仓块煤精准落煤自动控制系统,对移动检测仓位过程建立数学模型,将仓位信息与配仓小车自动化控制联系起来,能够通过随车安装雷达料位计收取的仓位信号实时调整小车运行速度,实现控制工艺和仓位数据的协同,另外对配仓小车定位误差问题及料位计仓位误差问题进行了分析和处理,提高了系统精度。赵庄矿选煤厂的现场运行表明,该系统能够实现煤仓仓位监测与配仓小车自动化控制的协同一体,小车自动化运行及精准落煤情况良好,仓位检测准确,同时减少了传感器件数量,降低了维护成本,节省了人力物力。

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.
