摘要:
针对煤矿巷道等恶劣环境下顶底板移近量监测难题，采用激光相位测距技术，设计了一种低功耗无线激光移近量传感器。通过实验研究，该传感器实现了高精度测量，误差控制在3 mm以内，有效提升了测量准确性。同时，传感器在低功耗模式下整机功耗降至5 mW以内，显著延长了使用寿命。采用LoRa无线传输技术和WaveMesh网络，实现远距离自组网，方便安装使用。实验结果表明，该传感器具有高精度测量、低能耗工作和无线自组网通信等优势，可广泛适用于矿山巷道顶底板移近量监测中。
Abstract:
A low-power wireless laser proximity sensor was designed using laser phase ranging technology to address the difficulty of monitoring the displacement of the roof and floor in harsh environments such as coal mine tunnels. Through experimental research, the sensor has achieved high-precision measurement with an error controlled within 3 mm, effectively improving measurement accuracy. At the same time, the overall power consumption of the sensor is reduced to less than 5 mW in low-power mode, significantly extending its service life. Adopting LoRa wireless transmission technology and WaveMesh network, achieving long-distance self-organizing network for easy installation and use. The experimental results show that the sensor has advantages such as high-precision measurement, low energy consumption operation, and wireless self-organizing network communication, and can be widely used for monitoring the movement of the top and bottom of mining tunnels.
