Temperature and Pressure Monitoring System of Exploration Borehole in Deep Mine

为了获取矿山勘探钻孔的温度和压力数据,提出一种将FBG传感器放入地勘钻孔中,并通过光纤光栅解调仪将光信号转换为数字信号,再通过STM32微控制器处理数据,最后通过LoRa无线传输技术将数据传回到上位机的监测系统。该系统将光纤光栅传感技术和LoRa无线传输技术结合起来,使系统具有测量精度高、抗干扰能力强、通讯距离远、功耗低的优点。

In order to obtain the temperature and pressure data of mine exploration boreholes,a fiber Bragg grating sensor is installed into the geological exploration borehole,and the optical signal is converted into electrical signal by the fiber grating demodulator,and then the data is processed by STM32 microcontroller.Finally,the data is transmitted back to the monitoring system of the upper computer through Lora wireless transmission technology.The system hasthe advantages of high measurement accuracy,strong anti-interference ability,long communication distance and low power consumption.
