The electronic fence is an intelligent perimeter system consisting of a pulse generator (host) and a front-end fence. The modern public safety electronic fence has evolved and improved to become a new type of perimeter alarm product. It has changed the traditional model of simple post-warning in the former perimeter protection and emphasized the use of blocking (visible fences, manufacturing of intrusion barriers) as The main and alarm (acousto-optical alarms can be linked with other security systems) are supplemented by the new concept of international perimeter security with the role of deterrence (reducing the desire to commit crimes), while the product overcomes the shortcomings of the AC grid that are fatal and affect aesthetics, and the traditional Compared with perimeter security systems such as infrared, microwave, and electrostatic induction, it has the advantages of low false alarm rate, free from terrain and environmental constraints, and high safety. It has been widely used in substations, factories, communities, schools, villas, warehouses, and airports. , military bases, detention centers, prisons and other places.
Pulse electronic fence system composition and principle
The electronic fence system is mainly composed of four subsystems: the pulse high-voltage front-end fence system, the pulse electronic fence host, the wiring system (city power, communication), and the control system.
Pulse electronic fence host is the core of the entire electronic fence system. It completes the occurrence of high-voltage pulses, monitors front-end high-voltage values ​​and alarm conditions, handles control signals such as arm/disarm and high/low voltage switching, and uploads alarm zones and alarms. Type four processes.
Among them, the control system can be divided into keyboard control system and computer software control system (computer software control system is divided into long-range direct control program and LAN remote centralized management program)
The pulsed electronic fence host scans every wire of the front fence 60 times per minute, and each pulse has a peak of 700-5000 volts, making it difficult for intruders to climb. In the event of a fault such as an open circuit, short circuit, or human damage, the system will issue an alarm signal corresponding to the zone and type of alarm. And can be used in conjunction with any alarm system to form a reliable and effective Internet of things mechanism.
Analysis of Pulse Electron Fence Advantages
The electronic fence is an intelligent perimeter system consisting of a pulse generator (host) and a front-end fence. At the same time, the pulsed electronic fence system is different from the traditional high-voltage power grid. The pulsed electronic fence system can identify intentional intrusions and unintentional intrusions. And can intelligently identify the location of the invasion to give effective block, will not cause personal injury. Compared with infrared contrast, it has the following advantages:
It belongs to physical protection. After the installation of pulsed electronic fence, it is equivalent to adding a height of 75-85cm to the fence to form a type of protective wall, which hinders the movement of intrusions. Infrared radiation is invisible light, and there is no intruding behavior. Obstructive effect
The role of deterrence is that the 5000V high voltage on the pulsed electronic fence alloy line corresponds to the deterrent effect of intruders and can reduce the probability of intrusion. Infrared emission does not have this function.
With low false alarm rate, the pulsed electronic fence is less influenced by the weather, and bad weather caused by rain, fog and dust storms will increase the false alarm rate;
Anti-destruction function, with detection circuit short-circuit open circuit alarm, improve the reliability of the system; poor anti-destructive performance of the radio.
A pulsed electronic fence is improved on the existing advantages and characteristics, and it has the following characteristics:
Four-line/six-wire compatible, meeting the needs of ordinary users and high-end users;
The shell is designed as a waterproof case, no need to increase the waterproof box, saving equipment costs;
Protection from the indoor to outdoor transfer, making the alarm early warning, while making the user's indoor activities more convenient.
