Intelligent area recognition method based on wireless mesh network and intelligent area system

Abstract

The invention provides an intelligent area recognition method based on a wireless mesh network, and relates to an area recognition method. At present, an intelligent area generally takes an intelligent distribution transformer terminal as an information data center, and the updating timeliness is poor. According to the technical scheme, the method comprises the steps that when slave equipment is powered on, the slave equipment actively registers from a network server to acquire an IPv6 address, and the network server synchronizes the IPv6 address and an equipment ID of the slave equipment to amain station; main equipment sends a query command to the slave equipment according to received slave equipment archive information; the main equipment actively reports the detailed archive information to the main station to form a list and sends the white list to the distribution transformer terminal main equipment of the corresponding area; and the distribution transformer terminal starts equipment and line topology structure recognition of the area according to the received white list and synchronously sends information returned after recognition to the main station, and an equipment and line topology graph of each area is formed on the main station. According to the technical scheme, the updating timeliness and convenience of wireless slave equipment archives and topology structures of the areas are improved, and install and play of the wireless slave equipment is achieved.

Description

technical field [0001] The invention relates to a station area identification method, in particular to an intelligent station area identification method based on a wireless mesh network. Background technique [0002] The smart station area is an important part of the construction of the smart grid. It is the hub connecting the two major links of power distribution and power consumption. Power compensation, etc. The equipment involved mainly includes: transformers in the station area, intelligent distribution transformer terminals, low-voltage collection concentrators, intelligent capacitors, intelligent circuit breakers, intelligent commutation switches, SVG, and user-side load acquisition equipment. At present, the realization of all the functions of the intelligent station area generally takes the intelligent distribution transformer terminal as the information data center: first, in the direction of uplink data monitoring, except for the transformer voltage, current and o...

Problems solved by technology

[0003] 1. Security issues: At present, most of the wireless solutions used are micro-power wireless working in the license-free frequency band. In terms of communication methods, the mesh network composed of its own communication protocol is mostly used, and there is also a lesser use of no self-organization In addition, due to reasons such as technical capabilities and costs, most wireless solutions do not adopt very complicated security mechanisms, which poses a great hidden danger in security;

[0004] 2. Management of wireless slave device files and line topology in the local area: Under the framework of the system, each station has only one local micro-power wireless mesh network, and the main device of the wireless network is the intelligent distribution network in the local area. The terminal is responsible for establishing a wireless network, and other wireless devices under this station area are slave devices
