摘要

针对顶煤开采过程中液压支架的振动测量与无线传输困难问题,设计了基于LoRa的振动无线测量传输系统.设计了基于STM32单片机和AD7606的振动采集硬件系统,实现对压电式振动传感器的信号采集.针对煤矿井下振动数据无线传输困难的问题,设计了基于LoRa的无线发送单元和接收单元,并采用串表压缩算法(Lempel Ziv Welch,LZW)对振动数据进行压缩传输,上位机接收、解压缩并分析处理数据.实验结果表明,设计的系统最多可以测量8个通道的振动信号,1 024字节数据在5dB信噪比条件下无线传输压缩率为70.46%,为液压支架的振动采集与无线传输提供了可靠的解决方案.

Abstract

To address the difficulties in measuring and transmitting vibration signals of hydraulic support during coal mining,a vibration wireless measurement and transmission system based on LoRaWAN was designed.A hardware system for vibration acquisition based on STM32 single chip and AD7606 was designed to collect signals from Piezoelectric vibration sensors.To solve the problem of difficult wireless transmission of vibration data in coal mine shaft,a LoRa-based wireless sending and receiving unit were designed,and a compression algorithm(Lempel Ziv Welch,LZW)was used to compress and transmit vibration data.The computer received,de-compressed and analyzed the data.Experimental results showed that the designed system could measure up to 8 channels of vibration signals,and the compression rate of 1 024 bytes data under 5 dB signal-to-noise ratio was 70.46%,providing a reliable solution for vibration acquisition and wireless transmission of hydraulic supports.
