Grid communication system based on Beidou system

Abstract

The invention discloses a grid communication system based on a Beidou system, which comprises a field acquisition system, a communication channel system and a master station system. The field acquisition system comprises a terminal module, a communication module, and an antenna. The terminal module is connected with an electric energy meter; the terminal module is in communication connection withthe communication module through a serial port; the communication module shields a connection wire through multiple wires so as to supply power for the antenna and perform data interaction; the antenna achieves data transmission with the communication channel system through a RDSS wireless link; the communication channel system comprises the Beidou satellite; the Beidou satellite communicates witha Beidou director in the master station system through the RDSS wireless link; the master station system comprises the Beidou director and the Beidou master control front-end processor; and the Beidou director is connected with the Beidou master control front-end processor through a communication cable. The system in the invention has the beneficial effects that a Beidou communication module anda Beidou antenna are added in the field acquisition system so that the system can better adapt to various use scenes and the problem of inconvenience of construction of communication wires in remote mountainous areas is solved.

Description

technical field [0001] The invention relates to the field of electric auxiliary equipment, in particular to a grid communication system based on the Beidou system. Background technique [0002] At present, the uplink channels of data acquisition in the power industry mainly use optical fiber, Ethernet, GPRS and other methods for communication. However, for sparsely populated mountainous areas, pastoral areas, and hydropower stations in deep mountains, there are neither optical fiber channels nor stable GPRS signal coverage, and there are many problems such as high cost and complicated construction and maintenance of new communication channels. Therefore, satellite communication is suitable for power data collection in remote mountainous areas, pastoral areas, and deep mountains, which can reduce input costs while ensuring timely and automatic data collection. The existing technical solutions cannot solve the above problems. For example, the Chinese patent "A Communication S...

Problems solved by technology

The existing technical solutions cannot solve the above problems. For example, the Chinese patent "A Communication System for Inductive Distribution Network" with the application number 201711330891.7 discloses a power grid communication system based on sensors for communication; the application number is 201721459667.3 The Chinese patent "A Power Distribution Terminal Communication System" discloses a power grid communication system using wireless communication technology. The above-mentioned technical solutions still need to rely on the construction of base stations and other supporting hardware to achieve operation, which cannot meet the needs of remote areas. Achieved with less investment
