Description

Technical Field

[0001] This utility model relates to the field of wind farm field control technology, specifically a 5G private network system for wind farms. Background Technology

[0002] With the rapid development of the new energy industry and the continuous expansion of wind farm scale, intelligent operation and maintenance are increasingly reliant on communication systems. Traditional wind farm communication methods have many limitations: Insufficient coverage means that when relying on public mobile communication networks, signal blind spots can easily form in the wind turbine tower (enclosed metal structure) and remote roads, failing to meet the continuous coverage requirements of the entire area inside the tower and the roads in the wind farm. Poor environmental adaptability; wind farms are mostly located in the wild, with large temperature differences between day and night and frequent sandstorms, making it difficult for ordinary communication equipment to operate stably in extreme temperature and sandstorm environments. With limited business support, smart operation and maintenance services such as real-time high-definition video backhaul and massive sensor data collection require high uplink speeds and low latency, which traditional networks cannot meet.

[0003] Therefore, there is an urgent need for a 5G private network system specifically designed for wind farms to solve problems such as incomplete coverage, security risks, poor environmental adaptability, and insufficient business support. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a 5G private network system for wind farms that is fully covered, safe and reliable, adaptable to extreme environments and supports multiple services, thereby solving the problems of incomplete coverage, insufficient environmental adaptability and service support capabilities of existing wind farm communication systems.

The multiple field base stations are respectively connected to the base station switch via on-site optical fiber. The base station switch is connected to the core switch. The core switch is connected to the private network 5GC module and the network management server. The private network 5GC module and the network management server are connected to the 5GC and IMS server display. The private network 5GC module is connected to the enterprise intranet via a firewall. The field base station includes a base station body and a power divider, a surge arrester, and a UPS module electrically connected to the base station body. The power divider is communicatively connected to the external antenna of the cabin, and the UPS module is electrically connected to the power distribution cabinet through a leakage current protector. The base station switch is also communicatively connected to a micro base station, which is electrically connected to a second power divider, and the second power divider is electrically connected to a second antenna.

[0006] Optionally, the UPS module is also electrically connected to a micro base station.

[0007] Optionally, the base station body is connected to the first grounding busbar of the surge arrester.

[0008] Optionally, the micro base station is connected to a second grounding busbar.

[0009] Optionally, the base station body is communicatively connected to the first GPS antenna.

[0010] Optionally, the micro base station is also communicatively connected to a second GPS antenna.

[0011] Optionally, there may be multiple power dividers, external antennas, and surge arresters.

[0012] Optionally, there may be multiple second power dividers and second antennas.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: This invention achieves precise full-area coverage of the wind farm through a collaborative architecture between the data center control subsystem and the on-site base stations. The base station within the wind turbine nacelle covers the entire wind turbine tower area via external antennas and power dividers, while micro base stations supplement other communication blind spots, ensuring high signal coverage. Simultaneously, surge arresters and grounding blocks conduct lightning-induced voltage to the ground, and a UPS module ensures stable power supply, adapting to the extreme temperature differences and sandstorm environments of the wind farm. The core switch and dedicated network 5GC module enable centralized data scheduling, and the network management server monitors network status in real time. Through this efficient network architecture and equipment collaboration, the system significantly improves the operation and maintenance efficiency of the wind farm. Attached Figure Description

[0019] The working principle of this utility model is as follows: The 5G private network system for wind farms achieves full coverage, secure transmission, and service support through the collaboration of components in the equipment room control subsystem and the on-site base station subsystem. Its working principle is as follows: The data center control subsystem, acting as the network hub, comprises base station switches 2, core switches 3, dedicated network 5GC modules 4, network management servers 5, firewalls 7, and the enterprise intranet 8. Base station switches 2 connect multiple field base stations 1 and micro base stations 19 via on-site fiber optic cables, responsible for aggregating front-end data.
