基于LoRa的校园配电数据检测系统设计

Design of Campus Distribution Data Detection System Based on LoRa

4G无线通信技术在校园配电数据监测中组网设备多成本高,ZigBee通讯采集的范围有限,基于Lo Ra的智慧校园电能数据的实时监测系统可降低成本且满足通信范围。监测设备通过电压互感器和电流互感器采集数据,通过STM32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。结合可控开关电路设计和待机等多运行模式,使得终端功耗明显降低。实测结果表明,设备通讯范围广且损耗低,可满足智慧校园的电能数据自动采集与传输需求。

4 G wireless communication technology has many network equipment and high cost in campus power distribution data monitoring.ZigBee communication limits the collection range.The real-time monitoring system of smart campus power data based on LoRa can reduce the cost and meet the communication range.The monitoring equipment collects data through voltage transformer and current transformer,processes the data through STM32 microprocessor and realizes the field storage function,and finally uploads the data to the server through LoRa wireless module.Combined with multi operation modes such as controllable switch circuit design and standby,the terminal power consumption is significantly reduced.The measured results show that the equipment has a wide communication range and low loss,which can meet the requirements of automatic power data acquisition and transmission in smart campus.
