Although the time perimeter protection system, the function of the system can't just stop at the alarm. First, it must be able to deter and block, and it must be able to alarm in time when the blocking is invalid.
Therefore, we advocate the use of tension-type electronic fences as front-end intrusion protection. The tension host reads the tension generated on the control rod at the same time to identify the tension value of each defense zone. When a certain defense zone at the front end is triggered by someone, the host will detect it. When the tension changes, when the preset threshold is exceeded, the tension host will alarm, and the host will transmit the alarm signal to the control keyboard through the communication bus. The keyboard will prompt which zone is alarming based on the information returned by the host. The linkage module will be linked to the corresponding output point and linked with the live video and sand table. The staff on duty quickly alarms through the alarm information of the keyboard and the video of the scene linkage.
In the traditional perimeter defense system, the use of pulsed electronic fences has certain limitations and has a strong deterrent effect. It uses high-voltage, low-energy pulses, although it will not cause direct harm to the human body, but once touched , There will be very strong inductance, which is very dangerous, and it is not suitable for many places such as schools.
When the tension type electronic fence is in operation, the front metal rods and tension wires and other mechanical parts are not charged, and no arc spark is generated; the front end does not emit electromagnetic waves, which will not cause pollution and damage to the surrounding environment. It mainly uses tension detection technology to realize the alarm function. It is an electronic fence with equal emphasis on blocking and alarming. It has both blocking and alarm functions and has a certain deterrent effect.
Its environmental adaptability is strong, and it is not affected by environmental factors such as greening, trees and small animals, and is not affected by temperature and climate changes, and is not limited by the height and tortuous degree of the terrain. It can automatically track the tension value according to the environmental temperature and The change of time keeps the tension alarm threshold updated in time to make the alarm stable and reliable.
In addition, the tension-type electronic fence can be linked with other security systems. When an alarm occurs, the electronic map of the alarm center or guard room can display the defense zone information and alarm location, which is convenient for security personnel to deal with the situation in time.
Tension type electronic fence mainframe is divided into single-defense zone mainframe and dual-defense zone mainframe. Each zone has its own switch alarm output, and the mainframe panel displays the working status of the zone in real time. Using AC and DC power supply (AC/DC: 16V-24V), the tension value of each tension line can be displayed in real time, so that the background system can monitor the situation of each defense zone in time.
