Abstract

The invention discloses an intelligent bridge and belongs to the technical field of telecommunication. According to the technical scheme, the intelligent bridge comprises a medium-voltage-side signal isolation and transceiving circuit, a low-voltage-side signal isolation and transceiving circuit and a signal processing and transmission control circuit, wherein a communication signal of a medium-voltage power line is sent to an input end of the signal processing and transmission control circuit through the medium-voltage-side signal isolation and transceiving circuit and coupled to a low-voltage power line through the low-voltage-side signal isolation and transceiving circuit after processed by the signal processing and transmission control circuit; and a communication signal of the low-voltage power line is sent to the input end of the signal processing and transmission control circuit through the low-voltage-side signal isolation and transceiving circuit and coupled to the medium-voltage power line through the medium-voltage-side signal isolation and transceiving circuit after processed by the signal processing and transmission control circuit. According to the intelligent bridge, the network connection of a medium-voltage power line channel with low-voltage power line channel is realized, and the technical problem of remote real-time uploading of a large amount of low-voltage power distribution and use information is solved.

Description

technical field [0001] The invention relates to an intelligent bridge capable of realizing the channel network interconnection function of medium-voltage / low-voltage power lines, which belongs to the technical field of communication. Background technique [0002] With the continuous deepening and development of smart grid construction, a large number of intelligent terminal equipment with remote communication and measurement and control functions need to be installed on the grid to realize the temperature of key nodes of transmission and distribution lines, the insulation level of insulators, the temperature of switch contacts, power distribution The parameters and operating status of electrical equipment such as transformers, as well as user power consumption information are monitored, transmitted or controlled, and a large amount of low-voltage distribution power consumption information is uploaded to the substation in real time for comprehensive analysis and processing. ...
