Electronic fences can be broadly divided into security electronic fences, animal husbandry electronic fences and zoo-specific electronic fences. The most common ones are security electronic fences, while security electronic fences are divided into pulse electronic fences and tension electronic fences, although we all know The pulsed electronic fence is live, and the tension electronic fence is uncharged, but how do you know the two fences?
The front end of the pulse electronic fence is charged, and the deterrent force is strong. After the pulse generator (host) is energized, the transmitting port sends a pulse voltage to the front fence, and the time interval is about 1.5 seconds, and the pulse stays on the fence is about 0.1 second. After the loop is formed on the front fence, the pulse returns to the receiving port of the host. This port receives the feedback pulse signal. Once the port receives the pulse signal, it will trigger an alarm. The disconnection caused by human damage will also cause the receiver to not receive it. Pulse signal. At the same time, the host will also detect the resistance between the two transmitters. If the front fence is damaged and cause a short circuit, the pulse master detects that the resistance between the two transmitters is too small and will also issue an alarm.
The front end of the tension electronic fence is not charged. As the name implies, the tension electronic fence determines whether the alarm is detected by detecting the tension value. The tension electronic fence adopts a new detection method and a special signal processing method to ensure that the environmental change does not cause the static value of the tension. The tension alarm value and the tension alarm threshold change. When an intruder forcibly crosses, the tension electronic fence detects the change of the tension value. If the tension value changes or exceeds the specified range value, an alarm will occur.
Although the pulse electronic fence and the tension type electronic fence are both electronic fences, their alarm principle is quite different. One is to detect the alarm according to the front end pulse circuit, and the other is to change the alarm according to the detected tension value. Only by understanding the electronic fence alarm principle can you better understand how the product works, in order to use these products more reasonably.
