The component of the electronic fence system

The electronic fence system is mainly composed of two major parts: the electronic fence host and the front-end accessories (terminal rod, establishment pole, alloy wire, etc.). Usually, the fence host is installed outdoors, along the original circumference The boundary fence (brick wall, cement wall or iron fence) is installed, and the alarm signal is transmitted to the electronic fence special platform software through the signal transmission equipment.

Electronic fence is the most advanced perimeter anti-theft alarm system at present. The system mainly consists of three major parts: electronic fence host, front-end accessories and back-end control system.

The electronic fence is a perimeter anti-theft alarm system, which consists of three major parts, namely the electronic fence host, the front-end accessories and the back-end control system.

The electronic fence system is mainly composed of electronic fence host + front-end accessories + control keyboard + perimeter management platform software, etc.

The electronic fence system is mainly composed of three major parts: electronic fence host, front-end accessories and back-end control system. Usually, the electronic fence host is installed outdoors along the original wall (such as brick wall, cement wall or iron fence), and the pulse host is also usually outdoors, transmitting the alarm signal to the back-end control center through the signal transmission device.

How to draw electronic fence cad system diagram

Electronic fence cad system icon annotation elements: The length of each defense area, the location of the electronic fence host, the number of fence lines, the communication power supply line, etc.; it is also necessary to refine the electronic fence host system diagram and clarify the equipment list.

I have seen the CAD floor plan produced by the stone electronic fence manufacturer, and I have also seen the CAD drawings of other companies. Basically, they distinguish the defense along the perimeter, and then draw the host defense area code, draw the terminal pole, line system, etc. Some also draw the power cord, the wiring method and model of the signal line, and the model name of the control equipment in the monitoring center, etc.

First of all, we need to open CAS and enter first. Then we open the construction plan, copy a copy to a new layer or create a new one. It is necessary to determine the location of the construction area and arrange the construction area to ensure the smooth progress of the construction.

What is the difference between the electronic fence host in the single defense zone and the electronic fence host in the double defense area?

The perimeter security electronic fence host is divided into single defense zone and double defense zone. The main difference is: cost single defense zone electronic fence system: that is, a host intelligently controls a defense zone. It is suitable for short perimeters, such as 100 meters and 200 meters.

Simply put, the dual defense zone host can monitor and alarm the two perimeter defense areas at the same time. The host of the single defense zone can only monitor and alarm one defense area. The size of the defense area depends on the length of your perimeter. The more defense areas, the easier it is to determine the direction of the invasion.

The use of the single defense zone expansion module is to expand one defense zone into two parallel defense zones. For example, your four-way alarm host is expanded into 2 defense zones through the single defense zone expansion module, becoming the 8 defense zone alarm host. The advantage of expanding the defense zone with resistance is that the type of defense zone can be set.

What is the functional difference between tension electronic fence and pulse electronic fence?

The functional difference between tension electronic fence and pulse electronic fence: tension electronic fence is generally composed of ordinary wire and tension detector.

The difference is big. First of all, in principle, the pulsed electronic fence, the alloy wire transmits the high-voltage pulse signal; the tension electronic fence, the alloy wire is not charged.

The main difference between the two is that the front-end equipment of the pulsed electronic fence is energized, and with sound and light alarms and linkage monitoring, it can cause great psychological deterrent to intruders; it is mainly used in: industrial parks, communities, villas, logistics warehouses, cultural relics protection sites, military bases, government agencies, etc.

High-voltage pulse electronic fence Features: It has the three functions of deterrence, gear resistance and alarm. It has a strong deterrence and a very strong sense of shock once touched. It has the functions of short-circuit and open-circuit alarm. The use of high-voltage and low-energy pulses will not cause direct harm to the human body.

Pulse electronic fence: Advantages: It has the three functions of deterrence, blocking and alarm. It has strong deterrence, strong environmental adaptability, and is not limited by the height of the terrain and the degree of twists and turns.

There is still a difference between the two types of fences. It mainly depends on what place it is used in. Take the perimeter security electronic fence as an example. There is electricity on the front-end fence of the pulse electronic fence, which integrates the two functions of blocking and alarm. It is mainly used in communities, villas, factory logistics parks, etc.

How to install the electronic fence

When the front-end fence of the electronic fence is installed, it should be based on the changes of different physical protection carriers in the perimeter. The installation methods of the front-end fence are different. The common installation methods can be divided into: auxiliary installation, wall ceiling installation, independent installation/ On-the-ground installation.

Electronic fence installation: first, assemble the terminal rod, load-bearing rod and intermediate rod separately; then select the corresponding position on the wall to fix the three rods separately; finally, hang the alloy wire, install the host, and debug.

Wire release: After all the brackets are fixed, the electronic fence network cable can be installed. The process of releasing the wire is the process of fixing the bare wire of the fence to the insulator of each bracket in turn.

Determin the installation angle of the perimeter fence:.Determine the angle and inclination direction of the perimeter fence according to the on-site situation and the requirements of Party A.

connect the high-voltage wire to the front end. At this time, this defense area can be tested when the power is on. The installation of the electronic fence is relatively simple, and the construction requirement is to make it horizontal and vertical. It is necessary to carry out seamless protection of the perimeter. I don't know if these are enough. If you don't understand, you can send me a private message and send you the details.

How is the construction of high-voltage pulse electronic fence wired? Is there a perimeter electronic fence system wiring...

1. Pulse electronic fence perimeter composition: controller, terminal rod, terminal rod insulator, intermediate rod, intermediate rod insulator, threaded wire- It is composed of wire connector, wire tensioner, warning sign, alarm, lightning arrester, alloy wire, high-voltage insulated wire, universal base and middle rod base, etc.

2. Generally, the pulse electronic fence pulse host and the rain box are placed between the two defense zones. For example, the circumference of 200 meters is divided into two defense zones, so the pulse host and the rain protection box are fixed at a position of 100 meters, that is, between the two defense zones, and supply power to the left and right defense zones through high-voltage lines.

3. The pulse electronic fence system cannot be connected to any other grounding system and maintain an independent grounding at a distance of more than 10m. 2 When the alloy wire is lengthened, the connector is connected reliably with a wire-wire connector. 3 The electrical pulse of this product will not harm the intruder, but joint factors should be avoided.

4. If the installation of the electronic fence is highThe degree is not high enough. In order to avoid unintentional touch by personnel, isolation walls or isolation nets should be installed on the outside or both sides of the electronic fence. 6 The pulsed energy of the electronic fence sometimes produces sparks, so there should be no flammable gases nearby.
