Description

AN EXTERNAL TRESPASS SENSING SYSTEM Technical Field

[1] The present invention relates to an external trespass sensing system on the basis of a net constructed by using coaxial cables to form a physical barrier and more particularly, to an external trespass sensing system capable of easily install to new net fence and an existing fence that is designed to the new net fence, monitoring attempts to defeat the physical barrier and sensing an area where the wires are cut to improve a security in the intrusion detection. Background Art

[2] Generally, a trespass sensing system is installed to an inner wall or underground of facilities or buildings such that an external object, animal or person(hereafter, refer to the intruder) must move or disturb the wire to gain entry into the secured location and detect the intruder entry and alert it into the facilities.

[3] The trespass sensing system has a main function for protecting from the intruder entry using anchor posts between which the wires are strung. The trespass sensing system may use such that one end of the fence is secured into the underground to protecting the intruder entry from the underground and also a barbed taut wires ars installed over the fence to protect from the intruder's climbing up the anchor posts.

[4] Fig. 1 is a perspective view schematically showing a generally trespass sensing fence. The trespass sensing fence 10 comprise a plurality of anchor posts 12 and a net 14 for protecting the intruder entry between anchor posts 12. A barbed rounded wires 16 are positioned on an upper portion of anchor posts 12 to protect from the intruder's climbing up the anchor posts.

[5] While, the trespass sensing fence 10 may use such that one end of the fence is secured into the underground to protecting the intruder entry from the underground and ground entry.

[6] However, the disadvantage ot the trespass sensing fence 10 shown in Fig. 1 is that if the net 14 of the trespass sensing fence 10 may easily cut by any tool, it is not protect the intruder entry from the underground and ground entry. Further there are no any means for detecting a cutting operation in the net and thus a supervisor may not easily check the intrusion area. If the intruded area is not repaired, still the intruder entry may continued.

[7] To solve these sisadvantages, a technology utilizes a plurality of camera or a round of inspection. However the technology is in need of observation by the supervisor own and a maintenance costs are expensive. [8] Recently, one of method for solving the disadvantage is that a trespass sensing system comprises the net 14 having optical cables wherein a laser beam incidence into the optical cables may detect the intruder entry. [9] The optical cables sensing system utilizes such that if the optical cables may pulled or cut, a change of reflection in a laser beam is calculated. In these cases, a controller detects the intruder entry or cut of the optical cables.

[10] However, the method of the optical cables sensing system have a following disadvantages. The system senses cut and deformation of the optical cables and thus it may not operate correctly if a typhoon or strong wind is occured. [11] Furthermore, the method of the optical cables sensing system needs expensive equipments such as an expensive optical cable, installation and maintenance costs. [12] Meanwhile, a magnetic sensing system utilizes a plurality of magnets using a magnetic force generated by the motion of a conductor through between magnetics. [13] However, the magnetic sensing system is inexpensive more than method of the optical cables sensing system in installation and maintenance costs. The system still may not operate correctly if a typhoon or strong wind is occured. [14] It was developed an electrostatics method such that electrostatics was sensed if a vibration or impact in a sensing system was occured. However, the electrostatics sensing system is inexpensive more than method of the optical cables sensing system in installation and maintenance costs. The system still may not operate correctly if a typhoon or strong wind is occured. [15] The magnetic, optical cables and electrostatics sensing systems are need further costs if it constructs new fence after remove the existing fence. [16] Therefore, a need has arisen in the industry for apparatus for providing intruder's climbing detecting means with secure anchor posts to efficiently and accurately monitor a secured area.
