基于LoRa通信的矿用低功耗无线传感器设计

Design of Mine Low Power Comsumption Wireless Sensor Based on LoRa Communication

在煤矿安全监控系统中,为降低电池更换的频率,必须最大限度地降低电池供电设备的整机功耗,对此设计一种基于LoRa通信的矿用低功耗无线传感器。该传感器采用矿用锂离子蓄电池供电,低功耗MCU微处理器及LoRa无线模块等硬件设计,并结合软件控制休眠模式切换方式,降低整机功耗,增加电池工作时间。

In the coal mine safety monitoring system,in order to reduce the frequency of battery replacement,the power consumption of the battery power supply equipment must be reduced to the minimum,a low power wireless sensor for mine based on LoRa communication has been designed. The lithium ion battery power supply,low power MCU microprocessor and LoRa wireless module hardware were used to design the sensor,combined with software control sleep mode switching mode,it reduced power consumption and increased battery working time.
