- 为保障矿工生命安全和矿井生产安全，解决现有风速监测设备易受环境影响、磨损较快、成本较高等问题，提出1种基于无线中继的巷道超声波风速监测系统，采用时差法测量三维风速，并结合LoRa无线通信技术实现数据的实时传输。通过设计合理的超声波传感器硬件电路，包括微处理器最小系统、供电电路、超声波发射与接收电路、数模转换电路以及LoRa无线通信电路，构建了适用于煤矿井下复杂环境的风速监测系统。研究结果表明：该系统具有高测量精度、低功耗、安装灵活等特点，经现场实验验证，测量误差不超过0.2 m/s，能够实现巷道全断面风速的长期在线监测。研究结果可为煤矿智能化通风系统的建设提供有效的技术参考。
- Abstract:
- In order to ensure miners’ life safety and coal mine production safety,and to address issues with existing wind speed monitoring equipment such as susceptibility to environmental influence,relatively rapid wear,and high cost,a roadway ultrasonic wind speed monitoring system based on wireless relaying is proposed.This system utilizes the time difference method to measure three-dimensional wind speed and incorporates LoRa wireless communication technology to achieve real-time data transmission.By designing appropriate hardware circuits for the ultrasonic sensor,including a minimal microprocessor system,a power supply circuit,an ultrasonic transmit/receive circuit,an analog-to-digital conversion circuit,and a LoRa wireless communication circuit,a wind speed monitoring system suitable for the complex environment of underground coal mines is constructed.The results indicate that the system features high measurement accuracy,low power consumption,and flexible installation.On-site tests verify that the measurement error does not exceed 0.2 m/s,thereby enabling long-term online monitoring of wind speed across the entire cross-section of mine roadways.The findings provide an effective technical reference for the construction of intelligent ventilation systems in coal mines.
