Abstract

The present invention relates to a routing protocol based on a Zigbee wireless communication network, which is used to construct a current differential emergency protection channel communication network for natural disasters, and belongs to the field of protection communication channels. The existing Zigbee network has many significant differences from the traditional MANET characteristic. The routing protocol of the present invention is composed of three parts: list establishment, route discovery and route maintenance. The routing protocol of the present invention is used to establish the communication route from the head end node to the end node of the transmission line, and is fully suitable for chain network and line current differential In the case of protection, it has the characteristics of short delay, low energy consumption, and multiple hops, which meets the data transmission requirements of emergency protection channels in disaster situations.

Description

technical field [0001] The invention belongs to the field of wireless sensor network construction of line longitudinal differential protection communication channels, and more specifically relates to a method for construction of communication network current differential emergency protection channels. Background technique [0002] With the rapid development of my country's economy, my country's electricity demand continues to grow, and the scale of electricity continues to increase. At present, the development strategy of "power transmission from west to east, mutual supply between north and south, and national networking" has been basically realized. Three inter-regional interconnected grids in the south, central and north have been initially formed, and an interconnected grid covering the whole country has begun to take shape. Once a failure occurs, the affected geographical scope and the number of users will become larger and larger, and the resulting economic losses will...
