Automatic remote wireless self-learning metering system and address pairing method

Abstract

The invention discloses an automatic remote wireless self-learning metering system and an address pairing method. The system comprises an automatic metering terminal, the automatic metering terminal is connected with a DTU data processing unit through a conducting wire, the DTU data processing unit is in wireless communication connection with a RCU data processing unit, and the RCU data processing unit is connected with an automatic metering master station through a wireless public network. The following technical problems in the prior art are solved: the automatic metering terminal in a wireless communication signal blind area has two communication modes: the mode of adopting a high-gain antenna and a mobile signal amplifier is long in construction period and high in investment cost; and the mode of using a low voltage power line as a channel cannot solve the uplink communication problem of the automatic metering equipment in the signal blind area if the low voltage power line is absent in the field or not the same transformer power distribution environment is provided; and if a RS485 or 5 network cables are used as intermediate channels, the communication distance of relaying a wireless public network signal to the signal blind area through a special device is short.

Description

technical field [0001] The invention belongs to metering automation technology, in particular to a remote wireless self-learning metering automation system and an address matching method thereof. Background technique [0002] In recent years, as an important part of the smart grid, the metering automation system has greatly improved the automation level of power marketing with the advancement of the smart grid construction. Metering automation terminal equipment is distributed along with power users, power plants, and substations. There are many types of terminal equipment and they are widely distributed. Some are far away in the mountains, some are deep in the factory building under the dam, and some are in the basement of the building. In these places, the wireless public network signal cannot be covered or not completely covered, resulting in low terminal online rate, success rate of information collection, data accuracy and other important assessment indicators of the me...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a remote wireless self-learning metering automation system and address pairing method to solve the existing technology. There are two ways to solve the communication of the metering automation terminal in the blind area of ​​the wireless communication signal: using a high-gain antenna And the mobile signal amplifier method has long construction period and high investment cost; the use of low-voltage power lines as channels cannot solve the problem of uplink communication of measurement automation equipment in signal blind areas in environments where there are no low-voltage power lines in the field or power distribution without the same transformer; use RS485 or Category 5 network cables As an intermediate channel, there are technical problems such as short communication distances in relaying public network wireless signals to signal blind areas through special equipment
