The difference between the pulse electronic fence grid 


  intelligent pulse electronic fence and use the difference between the high-voltage grid in fact referred to the electronic fence, people tend to think of the high voltage power grid and other key military defense targets used. This high voltage with a perimeter, an attempt to climb by a strong psychological deterrent and a fatal blow, to defend the goal to become the first barrier. In fact, this high-voltage power grid and electronic fence are essentially different. 


  First, from the principle of speaking, the high-voltage grid is charged more than 220V AC, the electronic fence is electrified 5000V pulse voltage; 


  second, the consequences of speaking from the catenary, high voltage power grid: Due to high voltage, high current, high energy, action at the intruder, the intruder can easily lead to disability and death; and the electronic fence: Although the high-voltage pulse, but due to the current, short duration of action, so less energy and will not harm the human body, only a sense of shock; 


  third , from the use of a functional perspective, high voltage power grid is blocking, deterrence and the main shock, while the electronic fence to block, and alarm deterrence based; 


  fourth, from the use of terms in the use of high voltage power grid has strict restrictions, electronic fence has now entered every corner of civilian; 


  fifth, electronic fence front-end is generally used to set up or existing perimeter fence, front fence wire, is machined from a special alloy by a special process, with a light weight, low resistance, corrosion resistance, etc., life is far better than the general wire fence, and the single-zone power consumption of no more than 1 degree per day, comprehensive cost-effective. And monitoring probes and so large linkage system can greatly reduce the workload of security, a significant reduction in the number of security personnel and costs. 


  Electronic fence is in European countries developed animal husbandry and widespread application of active defense and perimeter alarm system, originated in animal husbandry highly developed countries such as Australia and New Zealand, the application of the latest perimeter security concept, namely blocking, deterrence and Call the police. Drawing on the front end of the wire fence and advantages of the conventional high voltage power grid, lead to tangible and warning signs based on the intruder feel a deterrent effect on the energy control, to take the pulse voltage, long cycle voltage pulse, low energy, not It will cause casualties, and can provide early warning function in the center console. With the development of science and technology, electronic fence after a replacement has begun to gradually widely used in some large-scale infrastructure, such as: communications, power, military, transportation and other fields. And be in the civilian market, such as luxury villas, residential quarters and widely used. 


  Third, intelligent pulsed electron fence and technical parameters of high-voltage power grid 


  1, the electronic fence main technical parameters: 


  with any alarm system network use, easy to improve prevention levels. 


  Intelligent perimeter security barrier alarm system, front fence Each wire has charged, so that no intruder opportunity. AC grid system and have essentially different, it uses a high-voltage pulse (700-5000V) and low energy (less than 5 joules), and thus will not constitute a hazard to life, while the electronic fence flexible intermediate and special alloy wire rod, It does not support the body's weight, but also perceived intruders and send alarm signals to ensure safe and reliable system. 


  The figure is then followed by a resistor divider fence oscilloscope to host high-voltage output voltage, pulse width does not exceed two 100us, voltage amplitude ratio of 1: 1000 of the display (the actual output voltage of the high-pressure 5.4Kv): 


  System high pressure, low pressure two modes, the user can freely switch modes depending on the needs of the high-pressure mode can generate high voltage pulse peak 5000-10000V, the low-voltage pulse mode can generate a peak pulse voltage 700-1000v so. During the day, or who switch to low-voltage mode operation near the fence, which makes the front fence pulse crackdown less, if the security alert at night or higher, can be restored to the pulse peak 5000-10000V high voltage pulse mode. 


  Product Specifications: 


  A) 


  the peak output voltage: 5KV 10KV ~ 


  B) 


  output low voltage peak: 700 ~ 1000V 


  C) 


  output peak power: <. 10A 


  D) 


  pulse width (pulse duration): ≤ 0.1s 


  E) 


  pulse interval: 1s 1.5s ~ 


  F.) 


  pulse output power: 2.5mC 


  G) 


  pulse output energy: ≤5.0J 


  H) 


  system power consumption: 5W 


  2, the main technical parameters of high voltage power grid: 


  technical Specifications: 


  input voltage: 180 ~ 240V (50HZ) 


  rated output: 1 to 4 5000V high voltage pulse 


  OCS combat power: 40mc 


  pulse duration: ≤10ms 


  power consumption: <50W 


  works: 


  220V electricity through the sinusoidal power supply UPS (backup power) after the regulator into the main chassis. The microprocessor sends each booster single cycle sinusoidal voltage detection according to the program set up, after the boost supply network perimeter.When someone contacts, change the system automatically detects the grid current and comparative analysis, after the exclusion of false alarm is triggered, continuous output pressure, until compliance with a predetermined standard power unit until the blow. And instructs the display area OCS, audible alarm so that duty personnel quickly determine the alarm, and the alarm signal is sent via RS-485 interface.
