成されている。 FIG. 1 is an enlarged sectional view of a destruction detection wire for a metal-coated network fence showing an embodiment of the present invention.
This destruction detection wire 1 is used, for example, by being built into an aluminum-coated net fence that is stretched to prevent intrusion into steel towers, and is made of a hollow metal wire made of the same aluminum or aluminum alloy as the net fence. A hollow reinforcing layer 3 made of steel, glass fiber, plastic, etc. is provided on the inner periphery of the coating material 2 to be formed.
A plurality of signal wires 4 and reinforcing wires 5 are drawn through the hollow portion of the wire. Each signal line 4 is surrounded by the reinforcing layer 3 and the reinforcing wire 5. The signal line 4 is made of a coated copper wire, and the reinforcing wire 5 is made of the same material as the reinforcing layer 3.

抗として検知される。 As shown in FIG. 2, the plurality of signal lines 4 are composed of an open type signal line 4a and a closed loop type signal line 4b, and these signal lines 4a, 4b and the covering material 2
is connected to a receiver 6 with a self-diagnosis function at one end of the detection side of the destruction detection line 1. The open type signal line 4a is in an open state at the other end on the far side of the detection line 1 and is not connected to any other signal line or any conductive part, and the closed loop type signal line 4b is connected to the other end on the far side by combining two or more of them. are connected to each other to form a closed loop. Therefore, normally these signal lines 4a,
4b, the open type signal line 4a is detected as an infinite resistance, and the closed loop type signal line 4b is detected as a short circuit resistance.

を得ることができる。 Here, if the destruction detection line 1 is cut,
Since the open type signal line 4a may be connected to another signal line or the covering material 2 at the cut point, in this case, the open type signal line 4a is detected by the receiver 6 as a short circuit resistance. . In addition, when the closed loop signal line 4b is cut, there is a very high probability that two or more signal lines that have previously formed a closed loop will separate at the cut point and become open. , this closed loop type signal line 4b
is detected by the receiver 6 as an infinite resistance. That is, one end of the destruction detection line 1 is monitored by the receiver 6, and the open signal line 4 is monitored.
Disconnection information on the destruction detection line 1 can be obtained by detecting a change in the signal line a from an open state to a short-circuited state or a change in the closed-loop signal line 4b from a short-circuited state to an open state.

感じないようにすることが望ましい。 By incorporating the destruction detection wire 1 into a NetFence or using it as the metal wire itself forming the NetFence, information about the destruction of the NetFence can be obtained instantaneously, which is very useful for crime prevention. Destruction detection line 1
As for the method of assembling it into a netfence, it is not necessary that the material of the covering material 2 be the same as that of the netfence, but it is desirable that the material does not give an unnatural appearance.

ができる。[Effects of the Invention] As described above, when the destruction detection line of the present invention is cut, the open type signal line and the closed loop type signal line become short-circuited and open, so there is no detection at one end of the detection line. By keeping the receiver connected, disconnection information can be reliably detected. Also,
Since a reinforcing layer, reinforcing wire, etc. are interposed between the signal line and the sheathing material, there is extremely little risk of a short circuit between the signal line and the insulation becoming undetectable, unlike in the conventional case. Since the detection receiver can perform self-diagnosis at all times, it is possible to prevent false alarms due to abnormalities in the detection wire itself, and it is possible to provide a highly reliable destructive detection wire for a metal-coated network fence.
