Design Of Distribution Grid Parameter Detector Based On OneNet Platform

With the improvement of people’s living quality,life involves a variety of electrical equipment,which requires on the one hand the continuous supply of electricity and reasonable scheduling,on the other hand also put forward new requirements for power quality.This Page describes the power quality data detector,which is applied to the monitoring of power quality data at the end of the distribution network.It relies on the China Mobile Internet of Things OneNet platform to achieve remote monitoring of power quality data and improve the quality and rationality of residential power consumption.Power dispatch provides convenient,scientific data support.This paper mainly includes two parts,one is the collection of power quality data,the ARM controller as the core,the low-power measurement V9281 chip developed by VMA(Vango Metering Architecture)Acquisition technology,non-contact voltage acquisition technology to achieve current and voltage data acquisition.Second,based on China Mobile’s open IoT platform,a remote control terminal with friendly human-computer interaction interface,simple operation mode and strong adaptability was set up.2G mobile network technology and computer network communication technology were used to realize the remote monitoring of power parameter data.After a single device test and the overall system testing,the design of the detector nodes and network operation can be stable,to achieve the remote control voltage and current data acquisition.Overall,the system basically meets the functional requirements that can be designed by the system,has the characteristics of simple structure and strong anti-interference ability,and has certain market potential.
