Remote power quality monitoring system based on wireless sensor network

Abstract

The invention relates to a remote power quality monitoring system based on a wireless sensor network. The remote power quality monitoring system based on the wireless sensor network comprises sensor nodes, a network base station, a database service center and a user terminal, wherein the sensor nodes form the wireless sensor network in a sensor ad-hoc network mode, acquire power grid parameters and electric quantity in a monitoring area and transmit data to the network base station in a multi-hop routing mode, the network base station returns the data back to the database service center through GPRS, the data are stored on a server of the database service center, and users and power grid workers can visit a central server through mobile client sides in real time. However, the users can only know the household electric quantity consumption situation and historical electric quantity consumption data due to different authority limits, the grid workers can visit the central server in real time to obtain power quality parameters and meanwhile can remotely control the sensor nodes, the reliability, stability and transmission distances of data acquisition are improved / increased.

Description

technical field [0001] The invention relates to a remote electronic detection device, in particular to a remote power quality monitoring system based on a wireless sensor network. Background technique [0002] A wireless sensor network (Wireless Sensor Network, WSN) is a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner to cooperatively perceive, collect, process and transmit the perceived objects in the geographical area covered by the network. information, and eventually send this information to the owner of the network. [0003] At present, people pay more and more attention to remote monitoring of power quality. Many power supply stations have begun to build wireless-based power quality monitoring systems for remote monitoring of electrical parameters on lines and power consumption by users. In the traditional wireless power quality monitoring system, a single detection device communicates directly with...

AI Technical Summary

Problems solved by technology

In the traditional wireless power quality monitoring system, a single detection device communicates directly with the data center. There is no communication link between the detection devices, the distance of data transmission is limited, the anti-interference ability is poor, and the data is easily lost.
