LPWAN技术在鄂州民信闸重建工程中的研究与应用

Research and Application of LPWAN Technology in the Reconstruction Project of Ezhou Minxin Sluice

低功耗广域网LPWAN(Low-Power Wide-Area Network,LPWAN)在不同通信环境下运行效果相差较大,理论数据基本没有参照意义。为了使中小水利工程应用LPWAN有详实的参照数据,对其技术进行研究,给出LPWAN基站和单元的装配方法及一体式模块的研发思路,在鄂州民信闸重建工程中进行LPWAN组网;组网运行和测试的数据表明,距离对LPWAN通信效果的影响非常小,而遮挡物的性质、体积是丢包率增加的主要原因。测试统计了LPWAN在水利工程常见场景环境下的通信数据,并提出改善通信效果的方法。

Low-Power Wide-Area Network(LPWAN)has very different operation effects in different communication environment.Therefore,the theoretical data hardly have any reference value.With the aim to provide detailed reference data for the application of LPWAN in small and medium-sized water conservancy projects,this technology was tested and analyzed in the paper in order to provide the assembly methods of LPWAN base stations and units and R&D ideas for integrated modules,and carry out LPWAN networking in the reconstruction project of Ezhou Minxin Sluice;Networking operation and testing data showed that distance had little impacts on the LPWAN communication effects,but the nature and volume of the shelter constituted the main reason for the increase of packet loss rate.The communication data of LPWAN in the common environment of water conservancy project was listed and the methods to improve the communication effect were proposed in the paper.
