TECHNICAL FIELD [0001] The present invention relates to a multi-use coaxial cable and a crime prevention system using the multi-

The present invention relates to a multipurpose coaxial cable and a crime prevention / disaster prevention system using the same. The present invention is applicable to various types of products because it has various uses integrated into one product, and is particularly applicable to a crime prevention system.

The coaxial cable is surrounded by a copper wire and its periphery is insulated. Around the insulator, there is a conductor shielded by a net shape made of copper or aluminum. The shielding layer and the conductor forming the core form a concentric circle , Which is called coaxial cable and is used for TV antenna, high-speed data communication, cable TV or LAN (Local Area Network).

1, a conventional coaxial cable has a conductive line 1 made of a copper material having good electrical conductivity, a PE (polyethylene) insulating layer 2 surrounding the conductive line 1, A shielding layer 3 made of a conductive material such as copper or aluminum which surrounds the surface of the insulating layer 2 in a net shape and a polyvinyl chloride coating layer 4 covering the outside of the shielding layer 3, .

The PE insulating layer 2 formed between the conductive line 1 and the shielding layer 3 made of a conductive material is electrically insulated from the conductive line 1 and the shielding layer 3 Thereby preventing the electromagnetic interference from occurring, thereby transmitting a relatively stable signal from external disturbance or noise, and the PVC cover layer 4 is shielded from the external environment to protect the coaxial cable.

However, in such a conventional coaxial cable, the inside of the PE insulating layer 2 surrounding the conductive line 1 is not completely protected from external radio interference or noise because the inside of the PE insulating layer 2 is densely formed without pores therein Has come.

The prior art having the above-described structure prevents the interference of radio waves flowing through the conductive line 1 and the shielding layer 3 primarily by the PE insulation layer 2, The second insulated buffering action is performed by the air in the pores 2a formed inside the insulator 2, so that the noise during the propagation can be efficiently removed. In addition, since the pores 2a are formed in the PE insulating layer 2, the material is less in the material than in the prior art, and the manufacturing cost can be reduced economically.

However, when such a conventional coaxial cable is used in a crime prevention / disaster prevention system, since the static charge change caused by applying an external force or a vibration shock is small, it is easy to detect an instantaneous impact signal or, for example, Therefore, the signal is amplified. Therefore, it is vulnerable to noise.

FIG. 4 is a cross-sectional view of a multi-purpose coaxial cable according to a first embodiment of the present invention, and FIG. 5 is a structural view of FIG.

4 and 5, the versatile coaxial cable according to the first embodiment of the present invention includes an active spiral wire 10 made of a copper material having good electrical conductivity, an air layer 10 having a predetermined thickness surrounding the wire 10, (30) wrapped around the air layer (20), a cable (40) wrapping the surface of the insulation tube (30) linearly, and a conductive fine copper wire wrapping the surface of the cable (40) A shielding conductor 50 made of an aluminum material, and a covering layer 60 covering the outside of the shielding conductor 50 to finish.

The spiral wire 10 can be selectively configured to flow or be fixed by exposing it as a wire or by putting it in a tube.

The cable 40 may be arranged in a twisted (+, -) form instead of being linearly arranged. Arranging the cables in a linear (symmetrical) manner results in a smaller capacitance value and a larger capacitance value when arranged in a twisted pair. The cable 40 is constituted by a crime prevention and disarming device which will be described in detail later, and is a part that causes a change in the capacitance value so that the intruder can make an intruder judgment quickly by the movement of the intruder. It is preferable that the cable 40 is not constituted in the surveillance system of the security disaster prevention apparatus alone but is constituted in association with magnetism, which will be described later.

In the second embodiment of the present invention, the structure of the air layer 20 is omitted and the insulation tube 30 is directly attached to the spiral wire 10. The function of the coaxial cable having the configuration according to the second embodiment is the same as that of the first embodiment.

Next, a third embodiment of the present invention will be described in detail with reference to the drawings.

Fig. 6 is a cross-sectional view of a multipurpose cable according to a third embodiment of the present invention, and Fig. 7 is a structural view of Fig.

6 and 7, the multi-purpose coaxial cable according to the third embodiment of the present invention includes an active spiral wire 10 made of a copper material having good electrical conductivity, A cable 40 for wrapping the surface of the insulation tube 30 linearly and a cable 40 for wrapping the surface of the cable 40 in a net shape, A shielding conductor 50 made of a copper or aluminum material having good conductivity and a covering layer 60 covering the outside of the shielding conductor 50 to finish. In the third embodiment of the present invention, the optical communication cable tube 70 is additionally provided in the configurations of the first and second embodiments.

The spiral wire 10 can be selectively configured to flow or be fixed.

The optical communication cable tube 70 has a built-in optical communication cable. The optical communication cable tube 70 is built in a tube because, for example, it can be easily separated from other constituent parts at the time of repairing a fault and reconfigurable.

Since the insulation tube 30 isolates the optical communication cable tube 70 from the cable 40 to prevent signal interference, the communication function of the optical communication cable and the security function of the cable 40 interfere with each other And do so normally.

The cable 40 may be arranged in a twisted (+, -) form instead of being linearly arranged as in the first and second embodiments. Arranging the cables in a linear (symmetrical) manner results in a smaller capacitance value and a larger capacitance value when arranged in a twisted pair.

As in the first and second embodiments, the cable 40 is constituted by a crime prevention and disarming device to be described later in detail. When the movement is caused by an intruder, a change in the capacitance value . It is preferable that the cable 40 is configured not to be constituted in the surveillance system of the crime prevention and disarming device alone but in association with the magnetism.

The multi-purpose coaxial cable according to the first to third embodiments of the present invention has a large change in charge due to shaking or external impact due to the construction of the cable 40, so that it can be used as a sensing means of the anti- . FIG. 8 is substantially shown as being constructed by applying the third embodiment of the present invention. However, this is only an example, and the first and second embodiments may be applied.

As shown in FIG. 8, if a permanent magnet (magnet) 80 is installed in a fence in a state where the permanent magnet (magnetic) 80 is connected to any one of the constituent parts of the present invention, for example, the inner tube of the cable 40, The permanent magnet 80 is shaken by the intrusion of the intruder, and the magnetic field value changes as the permanent magnet 80 is shaken or shocked.

Accordingly, when the sensor 110 senses the change of the magnetic field and sends it to the control unit 200, the control unit 200 determines the shaking or external impact of the cable by a previously entered intruder determination program, .

The technology for carrying out the crime prevention and disaster prevention function using this principle is disclosed in a number of cases such as patent registration No. 10-1026080 (registered on March 23, 2011) and patent registration No. 10-0934988 (registered on December 23, 2009) It will be omitted because it has been described in detail.

Next, a fourth embodiment of the present invention will be described in detail with reference to the drawings.

9 is a cross-sectional view of a multi-use coaxial cable according to a fourth embodiment of the present invention, and FIG. 10 is a structural view of FIG. 9

9 and 10, a multipurpose cable according to a fourth embodiment of the present invention includes an active spiral wire 10 made of a copper material having good electrical conductivity, an air layer An aluminum shielding layer 90 surrounding the magnet 80 and an aluminum shielding layer 90. The aluminum shielding layer 90 surrounds the air tube 20, A shielding shield layer 100 surrounding the cable 40 and a covering layer 60 wrapping around the shielding shield layer 100 and covering the outside. The greatest difference between the fourth embodiment and the first to third embodiments is that a magnet (permanent magnet) 80 for the crime prevention function is constructed inside the coaxial cable.

The spiral wire 10 can be selectively configured to flow or be fixed.

The cable 40 may be arranged in a twisted (+, -) form instead of being linearly arranged as in the first to third embodiments. Arranging the cables in a linear (symmetrical) manner results in a smaller capacitance value and a larger capacitance value when arranged in a twisted pair.

A grounding cable or a sensing wire 85 is connected to the magnet 80 as a permanent magnet for causing a change in the capacitance value due to the flow of the cable. The sensing wire 80 is, for example, a sensor.

The aluminum shield layer 90 may be formed of tape or silver foil to insulate the magnetic 80 and the cable 40 from each other.

The shielding layer 100 may be formed of a copper foil or a silver foil.

According to the fourth embodiment of the present invention constructed as described above, the cable 40 can be formed of a plurality of slender metal plates, thereby widening the unit area, thereby increasing the variation in charge amount. Also, unlike the first to third embodiments in which the magnet 80 is formed outside the coaxial cable, the coaxial cable is constructed inside the coaxial cable, and by using the magnetic induction phenomenon generated when the active spiral wire 10 is shaken, Since it can react sensitively, change of charge amount and magnetic induction phenomenon can be detected at the same time, and it can be very usefully used for intruder detection.

11, the sensing wire 85 is connected to the magnet 80. Thus, for example, when the intruder is intruding into the coaxial cable of the fourth embodiment of the present invention, When the coaxial cable according to the present invention is touched, the magnet 80 is also shaken while the magnetic field value is changed. The value is transmitted to the control unit 200 at the remote place via the sensing wire 85, Be promptly judged and taken into account.
