Problems solved by technology

The current method of laying optical fibers is high in cost, long in cycle, complex in installation and operation and maintenance, and poor in scalability. It cannot achieve communication coverage of the entire scene and the entire production cycle, and cannot collect more on-site data in real time. It can only support the wind turbine control system and Stable and real-time transmission of main sensor data, other data, such as interactive data during operation, maintenance and repair, cannot be transmitted remotely, multi-point, and in real time Decentralized operation mode, resulting in unreachable communication terminals, high communication costs, limited data collection capabilities, and low efficiency

Embodiment 1

[0022] Such as figure 1 As shown, the wind farm fan wireless network system includes the following content,

[0023] The cabin wireless unit is used to provide wireless network signals to the surrounding area of ​​a wind turbine cabin. It includes an antenna, a cabin base station and an optical switch. base station connection;

[0024] The wind farm service unit includes an optical switch and a switch, and the optical switch is connected to the switch to access the operator's network;

[0025] Wherein, at least one nacelle wireless unit is networked to cover the wind farm, and the nacelle base station of at least one nacelle wireless unit is respectively connected to the optical switch of the wind farm service unit through an optical switch and an optical fiber.

[0026] Among them, the antenna adopts rod-shaped LTE omnidirectional antenna, and 2 pairs of antennas are connected to the cabin base station of the cabin wireless unit through the 7D-FB feeder. The nacelle base s...

Embodiment 2

[0030] see figure 2 , as an option, on the basis of embodiment 1, the wireless network system of this embodiment 2 also includes a roving wireless unit, which includes interconnected antennas and roving base stations, which are installed on the drone to provide wireless network signals to the surrounding area ; Wherein, at least one roving wireless unit moves cyclically along the outer edge of the wind farm and at least one nacelle wireless unit handover area according to the set trajectory during roving movement, and connects to at least one nacelle wireless unit network . Wherein, the junction area includes overlapping areas and non-overlapping spacing areas, and the range of the spacing area is smaller than the coverage area of ​​the base. In this way, the roving wireless unit can tour according to the preset track period, and cover the entire wind farm and the base station of the nacelle. When the signal in the handover area is not good or a base station in the nacelle f...

Embodiment 3

[0032] On the basis of the aforementioned embodiment 1 or embodiment 2, this embodiment 2 also provides a wind farm wind turbine wireless network management system, including the above-mentioned wind farm wind turbine wireless network system, an application terminal and a management computer room, and at least one wind farm server It is connected with the management computer room through Internet communication based on IP protocol, and at least one application terminal is respectively connected with the management computer room through Internet communication based on IP protocol.

Abstract

The invention discloses a wind power plant fan wireless network system, which belongs to the technical field of wireless networks, and comprises a cabin wireless unit which is used for providing wireless network signals for a peripheral area of a fan cabin and which comprises an antenna, a cabin base station and an optical switch, wherein the antenna is arranged at the top of the fan cabin, the cabin base station is arranged in the fan cabin, and the antenna and the optical switch are connected with the cabin base station; a wind field service unit which comprises an optical switch and a switch, wherein the optical switch is connected with the switch so as to access an operator network, at least one cabin wireless unit is networked to cover the wind power plant, and the cabin base station of the at least one cabin wireless unit is connected with the optical switch of the wind power plant service unit through the optical switch and the optical fiber. According to the system, a plurality of appropriate places are selected from the wind power plant to be set as wireless networking points, the coverage of the wind power plant is completed through the networking of base stations of the networking points, and communication coverage of the whole scene and the whole production cycle is achieved.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a wireless network system for wind turbines in wind farms. Background technique [0002] Our company has a wind farm (Qiuping Wind Farm) in the Xianggui Corridor. The area is mountainous, with Dupang Ridge in the east and Yuecheng Ridge in the west. The site covers an area of ​​about 30 square hectares, and the wind farm covers an altitude range of 300m to 1200m. The operation site has many points, is scattered, and has a vast area, and it is located in a mountainous area with few people and few resources. The current method of laying optical fibers is high in cost, long in cycle, complex in installation and operation and maintenance, and poor in scalability. It cannot achieve communication coverage of the entire scene and the entire production cycle, and cannot collect more on-site data in real time. It can only support the wind turbine control system and Stable and ...
