气动锚杆钻机冲击频率测量仪的设计

Design of Measuring Instrument of Impact Frequency of Pneumatic Anchor Drill

针对气动锚杆钻机冲击频率不易测量的问题,提出了一种新型气动锚杆钻机冲击频率测量仪的设计方案。该测量仪采用压力传感器采集钻机冲击信号,采用电压比较器和单稳态触发器处理冲击信号并输入到单片机,由单片机计算出钻机冲击频率。实际应用表明,该测量仪可准确、方便地测量出钻机冲击频率。

In view of problem that it is difficult to measure impact frequency of pneumatic anchor drill,the paper proposed a design scheme of new type of measuring instrument of impact frequency of pneumatic anchor drill.The instrument uses pressure sensor to collect impact signal of drill,and uses voltage comparator and monostable trigger to process the signal which is input into single-chip microcomputer to count impact frequency of drill.The actual application showed that the instrument can measure impact frequency of drill accurately and easily.
