Analysis of two key technologies of tension electronic fence
2019-08-23

For tension-type electronic fence products, the “anti-climbing” alarm of the rod and the environment of the tension line are adaptive, that is, the control rod and force rod at the front of the tension-type electronic fence should have the function of preventing climbing. The technology that automatically adapts to the environment and adjusts the alert tension value due to changes in the external environment and climate are two key technologies for this type of product.


Shaoxing No.1 Middle Tension Electronic Fence Installation

The "anti-climbing" alarm is mainly aimed at preventing the front control lever and the force lever from becoming the point of force for the intruder to climb over. Designed to install a sensitive sensing device on the front lever to set a certain trigger threshold. Once the intruder touches Or if the climbing strength exceeds the set value, an alarm will be triggered to prevent the intruder from overturning by lever. At present, some manufacturers on the market use vibration sensors inside the bars to determine whether there is an intrusion by monitoring the amount of movement of the fence. Obviously, in some special cases (such as high winds), false alarms may occur. Therefore, the tension electronic fence that meets the technical standards requires breakthrough improvements in detection technology.

金线的警戒张力阈值,由于合金线的物理属性,会受环境影响,进而张力值发生变化,特别是对于一些特殊安装环境,因此,环境自适应技术也成为各报警厂商技术实力比拼的要素。 The alarm issued by the tension electronic fence mainly depends on the alert tension threshold of the front alloy wire. Because of the physical properties of the alloy wire, it will be affected by the environment, and the tension value will change, especially for some special installation environments. Therefore, environmental adaptive technology Become an element of the technical strength of each alarm manufacturer. "Automatically adjust the alert tension value according to changes in the external environment and climate", that is, adapt to the surrounding environment according to the uncertain environmental factors around the installation area of the perimeter equipment, and reduce false alarms.



From the perspective of technical implementation, a climbing detection device is installed inside the tension electronic fence member, which can detect the pressure value of the fence member being stretched. At the same time, under this technology, the climbing alarm can also be directly located at the position of the member. In order to locate the intrusion point, it is one of the advanced technologies that can stably implement the "anti-climbing" alarm function.

For environmental adaptive technology, mainstream tension electronic fence manufacturers can intelligently identify the impact of the surrounding environment by improving the signal processing method, and accurately distinguish the difference between interference signals and intrusion signals. In actual application, when the front tension line is loosened due to the influence of external environment, climate and other factors, the self-tensioning spring can be automatically tightened to the alert tension value to ensure the stable and normal operation of the system. Shanghai Guangtuo V7 series tension electronic fence products can simultaneously implement a variety of intrusion alarm functions such as disconnection alarm, slack alarm, main unit power failure alarm, main unit and front-end detection bar tamper alarm, etc., and have improved the perimeter protection level in all directions. In the statistical data of the application of this kind of technology, the false negatives and false positives are significantly lower than those of other similar products. It can be called the industry's better technical representative of tension type electronic fence products.
