Wind power plant wireless network system based on plain open landform

Abstract

The invention relates to a wind power plant wireless network system based on plain open landform. The invention belongs to the technical field of wind power station wireless networks. The technical problem to be solved is to solve. How to construct a stable and full-coverage wireless network system suitable for a wind power plant station with an open plain landform is solved. The system comprisesat least one Mesh router arranged on a booster station, at least one Mesh fixed node device arranged at the top of a fan, at least one unmanned aerial vehicle carrying a Mesh module and at least one Mesh terminal. The Mesh router, the Mesh fixed node device and the unmanned aerial vehicle are interconnected to form a wireless backbone network, the wireless backbone network is connected with the wind power plant network through the Mesh router, and the Mesh terminal is accessed to the wireless backbone network through the Mesh fixed node device or the unmanned aerial vehicle. According to the invention, stable wireless network communication can be realized.

Description

technical field [0001] The present invention relates to the technical field of wind farm station wireless network, in particular to a wind farm station wireless network system based on plain open landform. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world with the advancement of technology and the development of environmental protection. In recent years, under the direction of national policies, China's grid-connected wind power has developed rapidly, and there are more and more construction projects for wind farms. [0003] At present, the construction of wireless Internet generally adopts the networking mode of wireless controller (AC) + thin AP (FIT AP), and its network topology is as follows: figure 1 As shown, the thin AP implements wireless signal processing, while user management, encryption, roaming, AP management and other functions are all centralized in the AC. However...

AI Technical Summary

Problems solved by technology

However, this networking method cannot be fully applied to the wireless communication network of wind farm stations, mainly for the following reasons: 1. Wind farm stations are generally located in remote locations, and mobile communication base stations cannot completely cover them; 2. The distribution of wind turbines is scattered, and the distance between them is average Between 300 meters and 3 kilometers, it is far away from the central control room of the wind farm, and the height difference between the top and bottom of the cabin inside the wind turbine is about 80 meters, and it is impossible to achieve full coverage of wireless signals; 3. The wind farm station The environment is relatively harsh and requires high reliability of equipment
