摘要
随着物联网和低功耗技术的发展,对局部放电数据传输介质的需求,正在由传统高速以太网转向低速485、窄带无线等.传统局部放电信号编码所对应的局部放电数据量大,难以依靠低速传输介质如485、窄带无线等完成局部放电数据的高效传输.文章分析了目前局部放电信号传输编码的现状,并总结出了一套适用于低速传输介质的局部放电信号传输编码.
With the development of Internet of things and low-power technology,the demand for partial discharge data transmission medium is changing from traditional high-speed Ethernet to low-speed 485,narrowband wireless,etc.Traditional PD signal coding has a large amount of PD data,so it is diffi cult to rely on low-speed transmission media such as 485,narrowband wireless to complete the effi cient transmission of PD data.This paper analyzes the current status of partial discharge signal transmission coding,and summarizes a set of partial discharge signal transmission coding suitable for low-speed transmission medium.
