A remote wireless self-learning measurement automation system and address pairing method

Abstract

The invention discloses a remote wireless self-learning metering automation system and address pairing method, which includes a metering automation terminal connected to a DTU data processing unit by wires, the DTU data processing unit and the RCU data processing unit are connected through wireless communication, and the RCU The data processing unit and the master station of metering automation are connected through the wireless public network; it solves the problem of the existing technology. There are two ways to solve the communication of the metering automation terminal in the blind area of ​​wireless communication signals: the use of high-gain antennas and mobile signal amplifiers has a long construction period , High investment costs; using 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; using RS485 or Category 5 network cables as intermediate channels, through special equipment. There are technical problems such as short communication distance between network wireless signal relay and signal blind area.

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...
