Design and Installation of Guangzhou Ailifu Pulse Electronic Fence
The basic principle of the pulse electronic fence is to send out high-voltage pulses. It is an intelligent perimeter system composed of a pulse generator (host) and a front fence. It has perimeter prevention functions such as anti-theft and alarm. The electronic fence for modern public safety has evolved and improved to become a new high-tech intelligent perimeter alarm product.
Compared with the traditional perimeter security systems such as infrared, microwave, and electrostatic induction, pulse electronic fences have obvious advantages such as low false alarm rate, freedom from terrain and environmental restrictions, and high security. , Schools, villas, warehouses, airports, military bases, and other industries.
Design and installation:
The design of the electronic fence is based on different security levels, and the appropriate electronic fence can be configured to meet the requirements. Security levels are usually divided into three levels:
(1) Deterrent-a defense zone is set up around the perimeter, such as a 4-wire system installed on the top of a wall. With blocking alarm and deterrent effect.
(2) Medium security level. The length of each defense zone is not more than 300 meters, and more than 300 meters should be divided into multiple defense zones.
(3) Higher security level. The length of each zone is set between 100 meters, and the entire fence is divided into multiple zones. Each zone has its own independent trigger alarm, which can indicate the zone where the alarm is located. Alarm output is usually linked with other security systems such as CCTV, infrared beam, spotlight, alarm, etc. In actual use, the length of each zone should be set according to the length, terrain and economic needs.
The installation of electronic fences is divided into three basic installation forms: free-standing, auxiliary and wall-mounted according to their installation positions on the site.
A free-standing electronic fence is erected directly on the ground. Its height is about 2 meters, and generally 10-12 cables are installed. Considering the equipment and personal safety, it is required to install a protective wall or fence of no less than 1.2m on one or both sides of the free-standing electronic fence. The clearance between them should not be less than 1m. Keep the normal working area of ​​the free-standing electronic fence in an enclosed area that is generally inaccessible to the public.
The attached electronic fence is attached to the fence. The attached electronic fence is mainly used in places with higher security requirements without occupying peripheral land. There are three requirements for the existing fence. First, the fence should have sufficient fastness to withstand the tension and pressure of the electronic fence. The second is that the height of the surrounding wall should not be less than 2m. Third, the mesh of the fence must be less than 50mm to prevent people from reaching into it and touching the electronic fence attached to the inside of the wall. Wall-type electronic fences are more popular in China and are erected above or to the side of existing fences. It can be installed vertically or at a certain angle. The height of the electronic fence is about 0.8m.
