摘要
针对现有放顶煤工作面采用人工操作方式放煤存在随机性强、放煤效率低等问题,设计了综采工作面放顶煤自动控制系统。该系统采用煤矸识别传感器采集、分析、处理煤块和矸石撞击支架尾梁产生的振动信号,以判断煤块和矸石的下落状态,并将处理结果通过ZigBee无线收发装置发送给支架控制器,支架控制器依据检测结果自动控制放煤支架动作,从而实现放煤过程的自动控制。
In view of problems of large randomness,low efficiency of coal caving of artificial operation for top coal caving mining face,an automatic control system of top coal caving on fully-mechanized coal mining face was designed.The system uses coal gangue recognition sensor to collect,analyze,process vibration signals generated by coal and gangue impacts tail beam,so as to determine the whereabouts condition of coal and gangue,and the processing results were sent to support controller by ZigBee wireless transceiver,then the support controller automatically control coal caving support action according to test results to achieve automatic control of process of coal caving.
