Compared with the pulse type electronic fence, the tension type electronic fence has no perfect function and the anti-theft function may be slightly inferior to the pulse type electronic fence in function, but it is more meticulous than the pulse type electronic fence in the alarm detail. And this kind of fence is more used in the protective fence made of metal.

1、 Concept

(1) Pulse type electronic fence is the most common electronic security fence equipment in our life. In fact, the role of pulse fence can be simplified into two parts: anti-theft and alarm. Because the structure of the fence is composed of charged pulse electronic cable, when someone attacks the electronic security fence, the electronic cable can produce non lethal pulse high voltage to effectively repel the intruder and play a role of anti-theft. At the same time, the system will also send the intrusion signal to the system management terminal to remind the security personnel to pay attention, thus achieving the function of alarm. So it is a combination of anti-theft alarm.

Due to the good anti-theft characteristics of pulse fence, and the ability to work independently is also very strong, so whether it is government agencies or civil security field, can often see its shadow. In addition, because of its strong anti-corrosion ability, it is also more used in relatively harsh environment.

(2) Tension type electronic fence is a collection of mechanical and electrical devices that can prevent human body from crossing obstacles and sense the intrusion of climbing, pulling and cutting obstacles. It is a new type of perimeter intrusion prevention alarm facility. It is composed of control module, control rod, stress bar, support rod, wire rope, spring, fastener, etc. Tension type intelligent electronic fence adopts new detection method and special signal processing method. Ensure the change of environment, completely change the previous perimeter security detector environmental adaptability, easy to false alarm. Therefore, the tension type intelligent electronic fence can always be loyal to duty and work stably and reliably in the harsh environment of wind, frost, rain and snow, sand and dust, and high temperature.

Because the biggest difference between the tension type electronic fence and the pulse type electronic fence is that when the tension electronic fence works, the external devices including the tension cable are not charged, which has a more protective effect on the personal safety of students. Moreover, the tension type electronic fence has the minimum damage to human body and radiation, which can not only play a role in safety prevention, but also reduce the impact on students Human injury. Among all kinds of electronic fence facilities, tension type electronic fence is the most suitable security facilities for schools.

Function and application of tension type electronic fence and pulse type electronic fence

2、 Function description

(1) Pulse electronic fence is an active intrusion prevention system, which counterattacks the intrusion attempt, repels the intruder, delays the invasion time, and does not threaten human life. The pulsed electronic fence is composed of the electric cable with charged pulse. The non lethal pulse high voltage generated by the electronic cable can effectively repel the intruder, and send the intrusion signal to the monitoring equipment of the security department, so as to ensure that the management personnel can timely understand the situation of the alarm area and deal with it quickly.

(2) Tension type electronic fence is generally composed of ordinary metal wire and tension detector. The system is connected with various types of regular wire through tension detector. Each tension detector converts the human and mechanical force (force change) of any attempt to climb or cut the wire into an electronic signal and send it to the control center to achieve the purpose of alarm. When the tension type electronic fence is affected by external force, it will be converted into electronic signal according to the different force, so as to complete the alarm work.

Compared with the pulse type electronic fence, the tension type electronic fence has no perfect function and the anti-theft function may be slightly inferior to the pulse type electronic fence in function, but it is more meticulous than the pulse type electronic fence in the alarm detail. And this kind of fence is more used in the protective fence made of metal.

3、 Applicable place

(1) Pulse type electronic fence is applicable to any place (such as military base, government agency, judicial system, key cultural relics site, border, private residence, real estate agent, industrial area, factory, warehouse, etc.). On existing perimeter fence, fence, or self-supporting installation. The system automatically adapts to the change of environmental conditions and field conditions. It varies according to regional conditions. For example, in foggy days and windy sand days, the system can maintain the highest alarm value. It is easy to construct, no welding is needed, and it will not be threatened by erosion.

(2) The tension type electronic fence is suitable for the outdoor peripheral fence composed of metal wire (such as: ordinary wire, double braided wire, barbed wire, etc.). The weather has little effect on the system. It is suitable for schools, military facilities, airports, industrial sites, petrochemical and other places.
