Intelligent electric energy measuring remote metering system

Abstract

The invention relates to an intelligent electric energy measuring remote metering system which comprises an intelligent ammeter, a data acquisition unit, a second power line modulator-demodulator, a low-voltage power network, a first power line modulator-demodulator, a concentrator, a second modulator-demodulator, a data communication network, a first modulator-demodulator and a remote server meter-reading center, wherein the data acquisition unit is embedded on the intelligent ammeter and is used for automatically collecting, treating and sending the electricity consumption information and the charging information of the monitored electric equipment; the data acquisition unit is used for converting the collected electricity consumption data into the data format fit for power line carrier transmission through the second modulator-demodulator and performing output transmission through the low-voltage power network; the data which are transmitted in a carrier manner by the low-voltage power network is subjected to data format conversion through the first power line modulator-demodulator; and the data after format conversion are transmitted to the concentrator. The intelligent electric energy measuring remote metering system provided by the invention has the advantages of high technical level, high reliability, data accuracy, good adaptability, complete function, small module volume and low power consumption.

Description

technical field [0001] The invention relates to an electric meter telemetry system, in particular to an intelligent electric energy measurement telemetry system applied in the field of power supply and distribution. Background technique [0002] With the rapid development of electric power construction, the scale of power grid continues to expand. In many cases, the construction and equipment maintenance of power grids are becoming more and more frequent. The transmission line as the link of power transmission has the characteristics of long distance, large dispersion, and difficulty in inspection and maintenance. The following Tricon product "online monitoring system for transmission line status" can monitor the status of transmission lines very well. [0003] Automatic meter reading system refers to a new technology that uses communication and computer network technologies to automatically read and process meter data. The development of automatic meter reading technology...

AI Technical Summary

Problems solved by technology

[0005] At present, although some automatic meter reading systems have appeared in China, the installation volume is not large, and the technology is not mature, and the stability of data transmission is not high, so there is still a large room for development in the research of automatic meter reading systems
