A cable sensor is a coaxial cable in which a supporting dielectric is filled between an inner conductor and an outer conductor, and a charged charge of the supporting dielectric is generated by minute deformation of the inner conductor and the outer conductor due to vibration, and an electric signal is generated. It is taken out as.

り崩落の予兆を検知することができる。In the disaster prevention system described in Japanese Patent Application Laid-Open No. 10-11677, optical fibers are arranged in a grid so as to cover a rock slope. Since the amount of transmitted light decreases when an optical fiber is subjected to an external stress such as tension, bending, or compression, a sign of collapse can be detected by detecting the decrease in the amount of transmitted light.

点がある。In such a conventional disaster prevention system, a special cable sensor or an optical fiber must be provided on the slope. Since such a distortion detecting means is generally expensive, there is a problem that the system becomes expensive if it is intended to cover a large area collapse danger point.

る。DESCRIPTION OF THE PREFERRED EMBODIMENTS In a slope monitoring system according to the present invention, when a crack or swells on a slope or cliff, a wire stretched in close contact with or very close to the rock slope is pulled, and the switch is turned on. The movable piece of the means contacts the fixed contact. The monitoring means recognizes the abnormality of the slope by the conduction of the switch means, and notifies the monitoring person of the abnormality, for example. In response to the notification of the abnormality, the observer can quickly take necessary measures such as going to the site where the abnormality has occurred or prohibiting traffic on a road or the like affected by the slope collapse.

ので引張られ、スイッチ手段が導通する。[0009] In order to more accurately capture small fluctuations occurring on the slope, it is preferable that the wire and the slope are in close contact with each other. However, since the slope is generally not linear, the slope and the wire cannot be connected simply by stretching the wire. A gap is likely to be formed between them. Therefore, the slope monitoring system according to the present invention may further include a tubular outer cover having flexibility and holding the wire movably therein, and the outer cover may be fixed or embedded on the slope. . That is, the outer cover bends or expands according to the movement of the surrounding ground or rock. Therefore, when a crack is generated or swells on the slope, the outer cover is deformed, while the inner wire slides freely and is pulled, and the switch means is conducted.

免れ得る。If the wire is extended when a predetermined tension or more is applied, the movable piece of the switch means can contact the fixed contact when an extremely large tension is applied to the wire. Since the tension equal to or greater than the stroke is absorbed by the extension of the wire, breakage of the switch means can be avoided.

易である。According to the slope monitoring system according to the present invention, phenomena such as cracks, slippages and uplifts, which are signs of the collapse of cliffs and slopes and rockfalls, can be captured with a simple configuration. It can be constructed at low cost and is easy to construct.

And a monitoring unit 7 that receives a detection signal from each detection unit 6 and determines a risk of collapse, and a notification unit 8 that notifies a monitor or the like of an abnormality. It is composed of The lower end of the detection wire 3 is fixed to a fixing anchor 4 which is driven into a strong fixed ground 2 which is less likely to collapse, while the upper end side is a slope 1
It is slidably held by a pipe-shaped holder 5 that is driven into the fixed ground 2 above. The distance between the adjacent detection wires 3 is appropriately determined according to the state of the slope or the like, but is generally preferably about several tens cm to several meters.

２が伸長する。FIG. 2 is a front view showing the detecting wire 3 and the detecting section 6. The detection wire 3 has a linear body 31 made of a strong thread (for example, a yacht thread) and a tension coil spring 32 that is an elastic body for absorbing an excessive tension when the tension is applied. ing. The detection unit 6 is a switch 61 having a movable piece 62 that can freely move. The upper end of the detection wire 3 is fixed to the movable piece 62. When the detection wire 3 is pulled, the movable piece 62 is fixed. The terminal 63 is brought into contact with the terminal 63 so as to conduct. In addition,
The spring constant of the tension coil spring 32 of the detection wire 3 is larger than the spring constant of a spring (not shown) that biases the movable piece 62 of the switch 61. That is, when tension is applied to the detection wire 3, the movable piece 62 first swings, and after the movable piece 62 contacts the fixed contact, the tension coil spring 3
2 elongates.

加わることを回避できる。The above-mentioned monitoring system detects a sign of the rock collapse or the sliding of the earth and sand by the following operation. When a part of the slope 1 rises due to a crack or swelling, the detection wire 3 that is in close contact with the raised surface is pulled. Then, the movable piece 62 of the switch 61 comes into contact with the fixed contact 63, and conduction between the two terminals 64 is established. When the amount of tension of the detection wire 3 is large, the tension coil spring 32 is extended and the tension is absorbed as described above, so that it is possible to avoid applying a large force to the switch 61.

止するなどの必要な措置を講じる。When the monitoring unit 7 detects that one of the plurality of switches 61 is turned on, it determines that an abnormality has occurred on the slope 1 and drives the notification unit 8. The notification unit 8 may be, for example, a warning lamp or a warning buzzer that visually or audibly notifies the monitor of an abnormality. Upon receiving the warning of the abnormality notification, the observer goes to, for example, visually check the location of the abnormality,
Or take necessary measures such as prohibiting the passage of roads, railroads, etc. below the slope.
