Electronic fence is the most advanced perimeter security alarm system. The system is mainly composed of two main parts: electronic fence host and front-end accessories. In general, the electronic fencing host is installed outdoors along the existing fence (such as a brick wall, cement wall, or iron fence). The pulse generator is usually outdoor and transmits the alarm signal to the back-end control center through a signal transmission device.
Introduction
Introduction The edit electronic fence is the most advanced perimeter security alarm system. It consists of an electronic fence host and a front detection fence. The electronic fencing host generates and receives high-voltage pulse signals, and generates an alarm signal when the front-end detection fence is in contact net, short-circuit, or open circuit state, and sends the invasion signal to the security alarm center; the front-end detection fence consists of rods and metal wires and other components. The composition of the physical perimeter. Multi-level networking can be achieved by controlling the keyboard or control software. An electronic fence is an active intrusion prevention fence that counters an intrusion attempt, repels an intruder, delays the invasion time, and does not threaten human life. It sends the intrusion signal to the security department monitoring equipment to ensure that the management personnel Can understand the situation of the alarm area in time, and quickly handle it.
The blocking effect of the electronic fence is firstly reflected in the deterrence function. A warning sign is hung on the metal wire. When you see it, it generates psychological pressure. When you touch the fence, there is a feeling of electric shock, which is enough to make the intruders stop them. Second, the electronic fence itself is A tangible barrier, with proper height and angle, is difficult to climb; if it is forced to break through, the host will send an alarm signal.
The development of electronic fences comes from Europe and the United States. The modern electronic fences are from Australia. The electronic fences are divided into security electronic fences and animal husbandry electronic fences and zoo-specific electronic fences. It has been widely used in China and has been successfully applied to major projects such as the Olympic Games, the World Expo, and the State Grid, and has become a major product in the field of perimeter alarm. In 2008, the national standard for electronic fences was promulgated. Its standard number is: GB/T7946-2008.
The main function
1. Completely and clearly demarcated high-voltage pulse electronic fences and electrostatic induction fences have a strong blocking and deterrent effect.
2. Intelligent alarm function with extremely low false alarm rate.
3, with alarm interface, can be linked with other security systems to improve the system's security protection level.
4. The electronic fence has the prominent features of "defense-based, alarm-assisted".
The composing and editing electronic fence system is mainly composed of two main parts: an electronic fence host and front-end accessories. In general, the electronic fencing host is installed outdoors along the existing fence (such as a brick wall, cement wall, or iron fence). The pulse generator is usually outdoor and transmits an alarm signal through a signal transmission device to the back-end control center.
Application area
The electronic fence is widely used in substations, power plants, water plants, factories, industrial heavy land, industrial and mining enterprises, material warehouses, residential quarters, villa areas, schools, airports, aquaculture and livestock farms, government agencies, and key projects. Cultural relics, military installations, prisons, detention centers, and other places that have walls and require walls.
Advantages 1. The electronic fencing host adopts the advanced perimeter security concept of “mainly blocking and supplementing the alarm” and combines “deterrence, blocking, alarm, and security” in one.
2. The unique touch screen detection technology enables the electronic fence to realize three alarm modes: touch net, short circuit, and open circuit.
3, controlled by a microprocessor with high reliability, the keyboard is simple and convenient.
4. Advanced pulse high-voltage output function: Each line in the perimeter has electric shock, making the perimeter electronic fence impeccable. Strongly prevent the formation of physical barriers, delay the invasion time, and strive for initiative for security.
5, the false alarm rate is extremely low, advanced alarm principle, anti-interference ability, accurate alarm, to overcome the technical defects of infrared, microwave, electrostatic induction, etc., the perimeter of all kinds of insulators are waterproof design, ensure the system can alarm at the same time , not affected by climate, plants, small animals and other factors.
6, no blind area, no dead ends, perimeter electronic fence can be erected with the terrain ups and downs, gate, corner can be installed.
7, safe and reliable, the system uses high voltage, low energy design ideas, will not constitute a life hazard to the human body.
8, high and low voltage conversion mode: Users can freely switch modes according to different needs. During the day, some people switch to the low pressure mode when operating near the fence, which can reduce the impulse strength of the front fence; at night or when high alert time is required, it can be restored to the high-voltage pulse mode. Many electronic fence hosts now have the ability to automatically switch between high and low voltages after setting the switching time.
9, can use mobile phone SMS for remote arm, disarm operation.
10. There is a linkage output interface that can achieve linkage with monitors and alarm centers. Network computer monitoring can also be implemented.
11, with a customized battery, in the case of power outages continue to work, after the call automatically converted into 220V power supply.
12. As an integral part of the perimeter fence, electronic cables can reduce construction costs and investment.
13, electronic fence also has a beautiful appearance, easy installation and maintenance, simple operation, without terrain restrictions, lower cost and other advantages.
