针对当前电能表计量数据采集精度低,且无法实现同步的问题,引入远距离无线电(Long Range Radio,LoRa)通信技术,开展电能表计量数据采集方法的设计研究。基于LoRa通信技术,设定电能表通信传输协议;进行离散化和滤波处理,去除电能表信号中的噪声;通过同步控制设计,确保电能表计量数据的同步采集。通过对比实验证实,应用文章提出的采集方法可以实现对电能表计量数据的同步高精度采集。

Aiming at the problem that the current metering data acquisition accuracy of watt-hour meters is low and synchronization cannot be realized,the design and research of metering data acquisition method of watt-hour meters are carried out by introducing Long Range Radio(LoRa)communication technology.Based on LoRa communication technology,the communication transmission protocol of electric energy meter is set;Discretization and filtering are carried out to remove the noise in the electric energy meter signal;Through synchronous control design,the synchronous acquisition of metering data of electric energy meter is ensured.Through comparative experiments,it is confirmed that the acquisition method proposed in this paper can realize synchronous and high-precision acquisition of watt-hour meter measurement data.
