摘要
针对GPRS无线通信技术在野外地下水文环境监测中出现的组网设备增多带来成本增高问题和ZigBee通讯出现的采集范围受限问题,设计一套基于LoRa的地勘钻孔水压水温的实时监测系统。监测设备通过水压和水温传感器采集数据,通过STM32F103RCT6微处理器处理数据并实现现场存储功能,最后通过LoRa无线模块将数据上传服务器。结合待机模式和多路可控开关电路设计,使得终端具有更低的功耗。试验结果表明,设备功耗低,通讯距离远,可满足地质勘探数据长期自动采集与传输需求。
Aiming at the increasing cost caused by the increase of networking equipment in the field monitoring of underground hydrological environment by GPRS wireless communication technology and the limited acquisition range caused by ZigBee communication,a set of monitoring system for water pressure and temperature of geological exploration boreholes based on LoRa is designed.The monitoring equipment collects data through water pressure and water temperature sensors,processes data through STM32F103RCT6 microprocessor and realizes field storage function,and finally uploads data to the server through LoRa wireless module.Combined with standby mode and multi-channel controllable switch circuit design,the terminal has lower power consumption.The test results show that the equipment has low power consumption and long communication distance,which can meet the needs of long-term automatic acquisition and transmission of geological exploration data.
