基于超长距低功耗数据传输技术(LoRa)的油库储油自动感知系统的设计

Design of Automatic Oil Storage Sensing System Based on LoRa Technology

针对石油库储油自动感知系统的采集需求,提出一种基于超长距低功耗数据传输技术(LoFa)的低成本无线温度﹑压力和液位监测的解决方案。该方案通过LoRa节点采集仪表数据﹐以星型组网方式上报给LoRa网关,利用内置容积表实现油罐液位﹑密度和质量数据的实时存储、显示以及报警功能。该方案具有兼容性好、通信距离远、部署简单、成本低的特点,具有广阔的应用前景。

Aiming at the acquisition requirements of automatic sensing system for oil storage in oil depots,alow-cost wireless temperature,pressureand liquid level monitoring solution based on long range data transmission technology(LoRa)is proposed.The scheme can be used to collect the instrument data through LoRa node,and report to LoRa gateway in the form of star network,and realize the functions of real-time storage,display and alarm of liquid level,density and mass data in tank by using built-in volume table.The scheme has the characteristics of good compatibility,long communication distance,simple deploymentand low cost,and has broad application prospects.
