Description

TECHNICAL FIELD

[0001] The utility model relates to 5G wireless communication technical field, concretely is a kind of offshore wind farm communication system based on 5G network. BACKGROUND

[0002] Offshore wind farm has become an important direction of wind power development in China due to its advantages of not occupying land resources, being basically unaffected by topography, high sea wind speed, large single machine capacity and the like. At present, offshore wind power single pile foundation is a commonly used type of foundation, which has the advantages of simple structure, convenient construction and good bearing performance. However, due to the unique geographical location of offshore wind farm and complex natural conditions, the existence of pile foundation changes the original flow field and forms vortex systems such as horseshoe vortex and wake vortex under the combined action of wave and current, which can cause scouring effect on the pile foundation, resulting in reduction of foundation burial depth, increase of cantilever length and reduction of bearing stratum depth. This not only reduces the bearing capacity of the foundation and the stiffness of the structure, but also can cause the vibration frequency of the foundation to decrease, induce structural resonance and cause structural damage, thereby threatening the safety of the wind turbine. In order to ensure the safety, integrity, applicability and durability of offshore wind farm building structure in long-term service, it is particularly important to monitor the safety of offshore wind power engineering structure.

[0003] At present, optical fiber ring network is basically used in offshore wind farm to realize the backhaul and control of facility and equipment data. The complexity of marine environment and the passage of ships can easily cause optical fiber breakage or damage, affecting the reliability of network transmission. The difficulty of repairing and laying submarine optical cable is much greater than that on land, and the repair period is long and the cost is high. Once the submarine cable is broken, the offshore wind farm will face a long time of wind turbine production data loss and communication interruption, which brings great trouble to the production and operation of offshore wind farm.

[0004] Therefore, it is urgent to build a wireless network as a backup network for submarine optical cable. The successful construction of wireless network can effectively solve the problems of long-time inability to obtain production data and send control information after the submarine cable is broken. It is also unnecessary to urgently start the repair work of submarine cable, and the repair work of submarine cable can be arranged when the repair window and sea conditions are suitable, which not only saves a lot of operation and maintenance cost, but also meets the requirements of power grid on the station.
