The invention discloses an electronic fence alarm
system. The
system comprises a plurality of
stainless steel wire ropes, a plurality of
wire rope fixing devices, a plurality of high-strength insulating
ceramic terminals, a plurality of tension detection devices, a main
tension control board and a high-
voltage generating device, wherein, the plurality of the
stainless steel wire ropes are sequentially and alternately arranged from the top down and are connected in series through high-
voltage leads; the plurality of the
wire rope fixing devices are respectively connected on two ends of each
stainless steel wire rope; two ends of each
wire rope are respectively and sequentially connected with one wire
rope fixing device and one high-strength insulating
ceramic terminal, the high-strength insulating
ceramic terminal on one end is arranged on a support bar, and the high-strength insulating ceramic terminal on the other end is connected with one tension detection device; the tension detection devices are fixedly arranged on the other support bar and are connected with the main
tension control board; and the main
tension control board is connected with the high-
voltage generating device, is used for receiving and
processing a tension
signal, and controls the high-voltage generating device to generate high-
voltage pulse in case of an alarm. The electronic fence alarm
system has an
active defense function without blind spots in perimeter precaution; and the system is adapted to various complex
terrain environments without precaution
dead space, thus being widely applicable to all places in need of perimeter precaution.
