A fence is a type of perimeter security system. An electronic fence is a state-of-the-art perimeter alarm system, consisting of an electronic fence control unit and front-end detection fences. The electronic fence control unit generates and receives high-voltage pulse signals and triggers an alarm when the front-end detection fence is in a state of contact with the wire, short circuit, or open circuit, sending the intrusion signal to the security alarm center. The front-end detection fence is a physical perimeter composed of poles and metal wires. Multi-level networking can be achieved through a control keyboard or software.
Fenced grazing saves manpower, facilitates the rational use of grassland, and improves grassland productivity. Biological fences also have the functions of preventing wind and sandstorms, improving natural conditions, and increasing efficiency.
