As the "new darling" in the field of perimeter prevention, the electronic fence has many advantages such as low false positive rate, strong deterrence, high safety factor and beautiful appearance. Whether it is a campus, a community or a government or enterprise unit, the factory and the electronic fence will exert great advantages to ensure the safe operation of all units. The electronic fence is divided into a tension electronic fence and a pulse electronic fence. The functions of the electronic fence are different, and the application occasions are also different. For the user, how to choose the right electronic fence product?
First, we need to understand the principles and functions of the pulsed electronic fence and the tension electronic fence.
The working principle of the pulse electronic fence is as follows: the high-voltage output end of the fence mainframe sends a high-voltage or low-voltage pulse voltage to the front-end fence, and the pulse voltage is looped back to the receiving port of the host on the front-end fence, and the pulse electronic fence main body detects that the loop on the front-end fence is normal. Whether or not, and send an alarm signal according to the fence status. If an intruder climbs and cuts the electronic fence, it will cause the pulse circuit to open or short, causing the host to alarm. At the same time, the front end of the pulsed electronic fence has a certain amount of pulse voltage, which will be intruder during the climber's climbing process. It produces a certain current impact, which is the purpose of deterring intruders.
Pulse electronic fences have a wide range of applications in residential areas, factories, government and enterprise units, airports and other occasions.
The tension electronic fence has special sensors and control processing equipment, which can judge the movement behavior of the intruder climbing or cutting the steel wire through the slight force change on the steel rope. The working principle is that when the detector detects that the change of tension reaches the preset alarm requirement, the control processing device sends an alarm signal, and the signal is sent to the monitoring center through the transmission line, and the guardian can automatically pop up the alarm through the alarm management software interface. The dialog box understands the type of alert at the scene and handles it in a timely manner.
Unlike the pulsed electronic fence, the tension electronic fence does not carry any voltage, has a higher safety factor, does not generate sparks, and can also play a certain blocking role. It has a wide application space in education places such as primary and secondary schools, kindergartens, and flammable and explosive places such as natural gas and oil tank areas.
In the future development, the design of the electronic fence is required to be more intelligent and user-friendly, so that it can distinguish the difference between non-malicious touch and malicious touch, thereby avoiding accidental injury and indirect injury; in addition, because the electronic fence is the perimeter The eyes and ears of the anti-intrusion alarm system require the perimeter anti-intrusion alarm system to conduct regular inspections on the electronic fence.
At the same time, the alarm management center should have the function of timing inspection of each subordinate equipment, so that the operation of the perimeter security intrusion alarm system can be grasped at any time, which is one of the important methods to improve the reliability of the system.
In addition, in the future development trend of Keou, there is the application of strengthening remote control technology in the electronic fence, which not only can improve the technical level and product quality of electronic fence. It can also provide users with great convenience according to the actual application. The main remote control functions include remote program upgrade, remote data acquisition, remote data update, remote parameter setting and remote linkage control.
