Composition is netted to be formed plus necessary framework.It is widely used in highway, railway, bridge, industrial and mining establishment, power station, warehouse, building garden
Isolation, defence and the warning to external world of all kinds of civil and military facility such as area, airport, prison, barracks.
If by the metal cable in fence with necessarily regularly arranged and with ground connection framework insulation, can apply to clue
High electric field pulse, such as applies certain tension force to clue simultaneously and is equipped with tension pick-up, just become " tension type electronic fence ",
Not only can deter and stop people and the animal of illegal invasion by high electric field pulse, can also be appointed by detecting tension variation handle
What attempt climbing, the manpower of line of cut clue, mechanical force are converted into electronic signal and are sent to control centre, thus realizing guarding against
And warning.
If using conventional fence as carrier, optical cable is contacted and is fixed with definite shape on, optical fiber in cable
The vibration of fence just can be experienced, just become " vibration type fiber fence ".Pass to the various disturbances of optical fiber by gathering fence
Data, processes through back-end analysis and identifies, can determine whether out different disturbance types, as climbing, pressing, cutting fence etc. directly
The detour behavior such as behavior and the walking in a range of humans and animals of fence circumference, excavation, thus realize warning and early warning.
So, be otherwise known as " optical fiber perimeter alarm system ".
To the harbour, nuclear power station, islands and reefs base, oil gas platform, submarine cable and the oil gas that are in seashore and sea and seabed
The warning under water such as pipeline and defence, then difficulty is much greater, the attack that they are subject to and destroying except coming in surface ship
Outward, also include frogman under water, dolphin, midget submarine etc. close to and invasion and torpedo destruction.
One of existing technology is the high anti-tensile fence laying under water similar to check cable, and this fence generally uses sea water resistance
The high-strength galvanized steel wire rope composition of corrosion, for hindering shelves, hooking frogman and the equipment drawing illegal invasion.But this technology can not stop
Frogman is to the invasion after fence cutting and destruction, nor judges invasion particular location.
The two of existing technology are to form fence using the galvanized steel rope of having insulation sheath, apply pulse electricity to hawser
Press and detect echo, for judging directly to invade the concrete orientation of (as cutting and shock etc.), but this technology is not provided that circumference
Early warning.Because the D.C. resistance of steel core is larger, except the scope of warning be restricted outer, for the close of invader's (thing) in addition it is also necessary to
In addition lay at the bottom with the sensor network of cable and optical cable and underwater installation composition (as active or passive sonar and magnetic pass
Sensor etc.), thus providing early warning.
The three of developing technology are to enclose cable using optical cable composition, using Fiber Analysis equipment, can determine that direct invasion
Particular location and invader's (thing) are a range of close to (by underwater sound signal).But because the optical fiber in optical cable is relatively crisp
Weak and be not provided that power supply, in order to power to active equipment under water, often still also need in addition lay at the bottom with cable, from
And early warning is provided.
