Dual-mode heterogeneous network communication system and method

Abstract

The embodiment of the invention provides a dual-mode heterogeneous network communication system and method. The dual-mode heterogeneous network communication system comprises a network center node, a station region information source node and a plurality of single-phase dual-mode nodes, wherein the station region information source node receives a station region transformer number, and broadcasts information source information including the station region transformer number and a phase sequence number to which a low-voltage power line belongs at fixed time on the low-voltage power line of each phase of a station region transformer; each single-phase dual-mode node receives the information source information, analyzes the station region transformer number and the phase sequence number which correspond to the single-phase dual-mode node, and sends the station region transformer number and the phase sequence number to the center node; the network center node receives information which includes power utilization information, the station region transformer number and the phase sequence number and is sent by the single-phase dual-mode node, and sends the power utilization information, the station region transformer number and the phase sequence number to a main station. According to the dual-mode heterogeneous network communication system, positioning of a station region to which the acquired power utilization information belongs and complete coverage of acquired data communication within a station region range are realized, and the data transmission reliability and the communication success rate in a power utilization information acquiring process are improved.

Description

technical field [0001] The present invention relates to the technical field of power communication, and more specifically, to a dual-mode heterogeneous network communication system and method. Background technique [0002] An important symbol of smart grid construction is the power user information collection system, which has developed rapidly in recent years. The current communication technologies of the power user information collection system are mainly power line carrier communication technology and micro-power wireless communication technology. [0003] Power Line Carrier (PLC) refers to a communication technology that uses a power supply line as a communication medium for data transmission. In order to ensure the reliability of communication, the available communication rate is low, and PLC can realize the identification of station area and line phase sequence; due to the strong time-varying power line load (impedance) and serious line interference, it is difficult fo...
