[

The tension change sensing unit 150 includes a sensing unit body 151 having a substantially H shape and a torque sensing unit 152 and a pair of wire clamps 153 mounted on the sensing unit body 151.

The torque sensing unit 152 senses a torque generated in the sensing housing 151 generated when the actuator wire 142 moves along the longitudinal direction of the tension detecting post 111 and detects a change in the tension of the sensing line 113 do.

By the tightening operation of the intermediate tensioner 192, the sensing line 113 can maintain the tension state. The tensor is disclosed in, for example, Patent Application No. 11946 (entitled " Tension Detection Security System ") in 2011, and thus a detailed description thereof will be omitted.

The operation of the conventional tension detection security system having such a configuration will be described with reference to FIG.

A force applied to one of the main sensing lines 113a from the outside is transmitted to the clamping disk 141 connected to the main sensing line 113a to which the force is applied through the intermediate tensioner 192. [ The clamp disk 141 connected to the main sensing line 113a to which force is applied is referred to as an external force applying disk 141 'for convenience of explanation.

A part of the force applied to one of the main sensing lines 113a is transmitted to a tension spring 193 coupled to another sensing line 113 coupled to the main sensing line 113a to be looped, (193).

When a force is transmitted to the external force application disk 141 ', the external force application disk 141' moves toward the intrusion position, that is, the position where the force is applied to the detection line 113.

When the external force application block 160 'moves, the actuator wire 142 moves in the vertical direction. The inert wire 143 maintains its position without being affected by the movement of the external force application block 160 '.

The actuator wire 142 moves in the vertical direction, and torque is generated in the sensing portion body portion 151 as the inert wire 143 maintains the position.

The torque generated by the sensing part body part 151 is detected by the torque sensing part 152 and transmitted to a control part (not shown).

The control unit (not shown) determines whether or not an intrusion has occurred based on the torque magnitude detected by the torque sensing unit 152, and controls a security device such as a warning lamp, an imaging camera, etc., Security work will be carried out.

When the force applied to the main sensing line 113a is removed, the external force applying disk 141 'and the main sensing line 113a are returned to their original positions by the elastic force accumulated in the tension spring 193.

On the other hand, the main sensing line 113a, which is externally applied with force, is bent by the sensing line restraining clip 180, so that a greater force is transmitted to the external force applying disk 141 '.

A conventional tension detecting security system having the above-described configuration is disclosed in Patent Application No. 700441 (entitled " Intrusion Detection Fence with Trip Wire and Common Actuator "

However, according to the conventional tension sensing security system, some of the forces applied to one of the main sensing lines 113a are coupled to the other sensing lines 113 coupled to the main sensing line 113a, There is a problem that a relatively small force is transmitted to the tension detecting unit 140 because the tension spring 193 is transmitted to the tension spring 193.

If a relatively small force is transmitted to the tension detector 140, a second problem arises that the intrusion can not be accurately determined.

Accordingly, an object of the present invention is to provide a tension detection type security system capable of preventing a force applied to a sensing line from being transmitted to another sensing line connected in a loop form.

According to the present invention, the above object can be attained by providing a tension detecting apparatus comprising a tension detecting pillar and a pair of anchor pillars standing on the ground at both sides of the tension detecting pillar, A plurality of sensing lines arranged at both ends so as to form a group of two loops so as to form a loop, a tension detector installed in the tension detecting pillar to detect a change in the tension of the sensing line, Wherein two sensing lines, which are coupled to each other at both ends of the sensing line, are referred to as a sensing linear group, and two sensing lines belonging to each of the sensing linear group An interlocking pin provided on the anchor post to be disposed between both ends of the sensing line; And a loop formed by a sensing line belonging to each of the sensing sunroof groups is wound around the interlocking prevention pin.

Here, the anchor pillar is installed so as to be placed on the XY plane when the direction of arrangement of the sensing lines is referred to as the X-axis direction and the direction perpendicular to the paper is referred to as the Y-axis direction so that the sensing lines can be easily wound around the interlocking prevention pins And a sensing line support plate extending from the ground support plate so as to be disposed along the Z axis direction and having sensing line mounting holes for mounting the sensing lines; The sensing line is installed to pass through the sensing line installation hole; And the interlock pin is coupled to the sensing line support plate so as to be perpendicular to the paper surface of the sensing line support plate.

Therefore, according to the present invention, when two sensing lines connected at both ends of a sensing line are bundled to be a sensing linear loop group, an interlocking prevention is provided to the anchor holding member so as to be disposed between both ends of two sensing lines belonging to each sensing linear loop group It is possible to prevent the force applied to the sensing line from being transmitted to the other sensing lines connected in a loop shape by inserting the pins and causing the loop formed by the sensing lines belonging to each sensing linear loop group to be wound on the interlocking prevention pins. When the force applied to the sensing line is prevented from being transmitted to the other sensing lines connected in a loop shape, a relatively large force is transmitted to the tension detecting unit so that the intrusion can be accurately determined.

[ The tensor is disclosed in, for example, Patent Application No. 11946 (entitled " Tension Detection Security System ") in 2011, and thus a detailed description thereof will be omitted.

The operation of the tension detection type security system according to one embodiment of the present invention having such a configuration will be described with reference to FIG. 15 to FIG. For convenience of explanation, when the termination detecting line 13b and the main sensing line 13a are divided into two sides of the tension detecting unit 40 and each of them is referred to as a sensing line segment group, It is assumed that intrusion occurs through the sensing line 13a.

The force applied to the main sensing line 13a belonging to the left sensing line segment group by the intrusion is transmitted to the main sensing line 13a which is exerted through the intermediate tensioner 92, the tension spring 93 and the spring connecting ring 94, Lt; RTI ID = 0.0 > 60 < / RTI > The conversion block 60 connected to the main sensing line 13a to which the force is applied is referred to as an external force application block 60 '.

Since the loop formed by the sensing lines belonging to each of the sensing linear loop groups is wound on the interlock prevention pin 71, the force applied to one of the main sensing lines 13a causes a loop to be applied to the main sensing line 13a Is prevented from being transmitted to the other sensing lines (13) coupled thereto.

When a force is applied to the external force application block 60 ', the external force application block 60' moves toward the intrusion position, i.e., the position where the force is applied to the sensing line 13. [

A tensile force is applied to the conversion spring 40 through the block linking ring 42 as the external force applying block 60 'moves.

When the tensile force is applied to the conversion spring 40, the conversion spring 40 is extended and the sensing lever 52 moves toward the external force application block 60 '(see FIG. 16). 17 is a view showing the movement of the sensing lever 52 when a force is externally applied to the sensing line 13 disposed on the upper side of the tension change sensing unit 50. [

As the sensing lever 52 moves, a change in the tension of the sensing wire 13 is detected by the load cell 53 and transmitted to the control unit 19.

The control unit 19 determines whether or not an intrusion has occurred based on a change in the tension of the sensing line 13 detected by the tension detecting unit 40. If the intrusion is detected, the control unit 19 controls a security device such as a warning lamp, It is possible to perform a predetermined security operation with respect to the user.

When the force applied to the main sensing line 13a is removed, the external force applying block 60 'and the main sensing line 13a return to their original positions by the elastic force accumulated in the conversion spring 40 and the tension spring 93. [

On the other hand, when external force is applied, the main sensing line 13a is bent by the sensing line restraining clip 80, so that a greater force is transmitted to the external force applying block 60 ' When compared to the case).

It is possible to determine whether or not the intruder intrudes through the main sensing line 13a belonging to the left sensing target segment group in the same manner.

On the other hand, in the above-described embodiment, the interlocking pin 71 is provided on the anchor support 12 so as to be arranged on the plane of the paper and perpendicular to the plane of the sensing line support plate 12b. However, as shown in Fig. 18, It is possible to dispose the interlocking prevention pin 71 'on the anchor support 12 such that the interlocking prevention pin 71' is disposed perpendicularly to the surface of the support plate 12a.

As described above, according to one embodiment of the present invention, when two sensing lines connected to both ends of the sensing line 13 are grouped into a sensing linear loop group, both ends of two sensing lines belonging to each sensing linear loop group Interlocking prevention pins 71 and 71 'are provided on the anchor supports so that the loops formed by the sensing lines belonging to each of the sensing linear loop groups are wound around the interlocking prevention pins 71 and 71' It is possible to prevent a force applied to the sensing line from being transmitted to another sensing line connected in a loop form.

When the force applied to the sensing line is prevented from being transmitted to another sensing line connected in a loop shape, a relatively large force is transmitted to the tension detecting unit 40 so that the intrusion can be accurately determined.

The anchor pillars 12 are formed so as to include the sensing line support plate 12b disposed along the Z axis direction when the arrangement direction of the sensing lines 13 is the X axis direction and the direction perpendicular to the paper surface is the Y axis direction The sensing line 13 is easily connected to the interlocking prevention pin 12b by connecting the interlocking prevention pins 71 and 71 'to the sensing line support plate 12b so as to be perpendicular to the paper surface of the sensing line support plate 12b, (71, 71 ').
