Description

{LAND SLIDE ALARMING APPARATUS}

The present invention relates to a device for alarming a landslide, and more particularly, to a device for warning a landslide by detecting the occurrence of a debris flow through a wire installed in a landslide occurrence area and a contact sensor connected to the wire through an insulator, A landslide warning device capable of monitoring landslides more effectively by informing a control center or generating an alarm signal.

In Korea, natural disasters such as earthquakes, typhoons, heavy rains, heavy snow, hail, lightning strike, and tsunami have caused economic damages of nearly 2 trillion won each year. Most damages are reported to occur in June ~ September . Especially, more than 75% of the total damage is caused by heavy rains and typhoons. The types of damage are not only the damage but also various types such as large-scale structure flooding, flooding, and large-scale slope collapse.

The behavior of the typhoon centered on the Korean Peninsula is showing a course of turning eastward in both the Pacific and the southern areas in spring and winter, but it is approaching to the summertime and going north. In July and August, the number of passing through the peninsula increases, And it is turning to the south again. Therefore, structural and engineering problems are decreasing due to the strengthened design standards every year, but the scale and incidence of natural disasters are increasing due to abnormal weather. Therefore, it is time to analyze and examine the large-scale disasters that require systematic and professional inspection of disaster characteristics and disaster prevention plan centering on past meteorological statistics and the possibility of occurrence every year.

Landslide is a phenomenon in which a large amount of rocks, fissure materials, and soil move downward along the slope, and it is caused by many factors such as the cohesion of the rock structure, the slope of the slope, the water content, the relative movement rate, It is divided into various forms such as rockfall, evangelism, activity, spread and flow.

In general, the phenomenon that topsoil and rock move downward along the slope by gravity is called gravity slope movement and can be classified into slip situation, slurry type, and granular type. The slurry is defined as a mixture of sediments and water mixed with water. Especially, soil and rock fragments are mixed with water and flow down along the slopes and valleys. The topsoil (weathering layer) is saturated with rainfall, And landslides that are moving are defined as debris flow.

In recent years, damage has been increasing mainly in mountainous terrain among various types of disasters due to intensive storms or typhoons in Korea. In addition, due to intensive rainfall and catchment topographical causes, fine grain loss occurs at an accelerated flow rate and sequential increases in density flow , But the exact mechanism has not been clarified yet. So far, it has been found that deokseok contains water and descends at high speed. It contains large particles larger than sand and tends to destroy the non-caking layer (surface layer) It is known to leave.

So far, Korea has focused on restoration rather than prevention as a countermeasure against mountain disasters. However, if a scientist analyzes the landslide in advance and predicts and observes landslides and dangerous areas in advance, it will minimize the damage caused by landslides.

At present, various methods for measuring the movement of mountain slopes are being carried out in order to identify signs of occurrence of landslides. However, it was difficult to accurately measure and predict the landslide occurring due to the complex combination of various factors merely by measuring the movement of slopes. Especially, in the case of landslide landslides, it is important to know the exact location and speed of landslides, but there is virtually no way to measure or predict them.

Accordingly, it is required to develop a landslide warning device capable of detecting the occurrence of landslide accidents such as the occurrence of landslides and line collapses at an early stage and minimizing the damage thereof.

On the other hand, in the case of a device for detecting and predicting a conventional landslide, the basic idea of detecting the movement of the gravel-like material on the surface of the slope surface has been occasionally occasionally mistaken for the movement of wild animals in the mountains.

The basic object of the present invention is to solve the problems of the prior art as described above. More specifically, one object of the present invention is to detect the occurrence of debris flow through a wire installed in a debris flow generation zone and a contact sensor connected to the wire through an insulator, And to provide a landslide warning device capable of monitoring occurrence of debris flow more effectively and minimizing damage caused thereby by transmitting or issuing a warning signal.

It is another object of the present invention to provide a landslide warning device that can warn landslides in the event of a landslide, and improve the accuracy of the alarms so that the movement of wild animals and the like is not mistaken for landslides.

In order to accomplish the above object and to solve the problems of the prior art, the landslide warning device according to the present invention is characterized in that one end thereof is fixed and one or more wires extending across a landslide monitoring area, A plurality of wire fixing members which are disposed on the outer side of the landslide winding zone and which are electrically connected to the other end of the wire and are electrically turned on by the tension of the wire, A sensor connected to the sensor for supplying power to the sensor; and a controller connected to the sensor for generating information on the occurrence of a landslide when the sensor is turned on, A warning signal generating unit And a communication unit connected to the control unit and transmitting the occurrence of the landslide to the external communication device when the detection sensor is turned on.

Here, the landslide warning device may include two or more wires including two or more wires, and two or more sensors connected to the respective wires, and the controller may notify the user of the occurrence of the landslide only when all of the two or more sensors are turned on .

In particular, the power supply, the two or more detection sensors are connected in series.

The sensing sensor may include a pair of non-conductive fixing parts formed at predetermined intervals in the middle of the pair of electric conductive parts, the pair of electric conductive parts being spaced apart from each other by a predetermined distance, And an elastic member disposed on the opposite side of the wire and having one end connected to the conductor and the other end connected to the fixing point.

In this case, the non-conductive fixing peg has a ground inserting portion which is inserted into the ground when fixing the non-conductive fixing peg to the ground below the electric conductive portion.

Meanwhile, the through-hole is formed in a size that does not allow the conductor to pass through the through-hole.

According to the above-described landslide warning device of the present invention, the wire is installed in the area where the earth and the earth is likely to be generated, and the force applied to the wire when the earth stone is generated is sensed through the detection sensor including the insulator connected to the wire, It is possible to obtain the effect of minimizing the damage by monitoring the occurrence of the debris flow at the beginning in a simple and more efficient manner.

In addition, according to the landslide warning device of the present invention, the switch connected to the wire is normally turned off in the normal state so that the landslide warning device maintains the power-off state, and when the landslide occurs, The connecting conductor is located between the conductors so that the contact sensor is turned on and the landslide warning device is switched to the power-on state. Thus, it is possible to effectively observe the occurrence of the collapse accident with the minimum energy consumption alone .

In addition, according to the landslide warning device of the present invention, it is possible to prevent the occurrence of landslides and to prevent the movement of wild animals from being mistaken for landslides, thereby improving the accuracy of landslide detection.

According to the landslide warning apparatus of the present invention, when a collapse of landslide and line collapse is detected, an alarm signal including the zone information is generated and transmitted to the management server, It is possible to obtain an effect of accurately recognizing the area where the landslide occurs and effectively coping with it.

In addition, according to the landslide warning device of the present invention, when a landslide such as the occurrence of landslides is detected, the area is transmitted to the management server of the disaster management center so that the manager located at the remote location can more accurately grasp the occurrence of the landslide The effect can be obtained.

Embodiments of the present invention will now be described with reference to the accompanying drawings. The following description and accompanying drawings are for understanding the operation according to the present invention, and parts that can be easily implemented by those skilled in the art can be omitted.

Furthermore, the specification and drawings are not intended to limit the present invention, and the scope of the present invention should be determined by the claims. The terms used in the present specification should be construed to mean the meanings and concepts consistent with the technical idea of the present invention in order to best express the present invention.

1 is a block diagram showing a configuration of a landslide warning device according to an embodiment of the present invention.

The landslide warning device according to an embodiment of the present invention includes a wire installation part 150 including one or more wires installed in a landslide monitoring area 10 for monitoring occurrence of landslides, And a switch box part 110 including at least one detection sensor for detecting whether a landslide occurs due to a tensile force of the switch box part.

Here, the switch box unit 110 includes one or more detection sensors s1 to sn and a control unit 112 connected to one or more wires w1 to wn of the wire installation unit 150, respectively. The switch box unit 110 further includes a warning signal generating unit 114 and a communication unit 116. Alternatively, the warning signal generator 114 and the communication unit 116 may be connected to a plurality of the switch box units.

The first wire w1, the second wire w2, the third wire w3 to the n-th wire wn may be respectively installed in the landslide monitoring area 10 . The landslide monitoring zone (10) can be implemented in various zones where collapses may occur, such as debris-generating zones or track zones. In this specification, for the sake of convenience of explanation, the case where the landslide monitoring area 10 is mainly embodied as a debris generating area will be described as an example.

The wirings (w1, w2, w3, ..., wn) extend laterally in the sloping landslide monitoring zone (10), wherein each of the wires Respectively.

The wirings w1, w2, w3, ..., wn are arranged on a sloping surface of the landslide monitoring area 10, 152, respectively.

For this, a lower end of the wire fixing hole 152 is inserted and supported in the topsoil, and an upper end portion of the wire fixing hole 152 is formed with an annular portion through which the wires pass.

The first wire w1 to the n-th wire wn are fixed to predetermined fixed points f1, f2, f3, ..., fn, respectively, and the second side is fixed to the detection sensors s1, s2 , s3, ..., sn, respectively, in the landslide monitoring area 10. The fixing points f1, f2, f3, ..., fn at which the first side ends of the wires are fixed can be set to a point at which the wires can be installed sufficiently across the landslide monitoring area.

For example, the first 1-1 side (the right side end in the drawing) of the first wire w1 can be set to a point at which the first wire w1 is positioned across the upper side of the landslide monitoring area 10 have. The second-1 side end (the right-side end in the drawing) of the second wire w2 can be set to a point at which the second wire w2 is positioned across the center of the landslide-monitoring area 10. The n-1-th end 131 of the n-th wire wn may be set to a point at which the n-th wire wn is positioned across the lower side of the landslide-

In addition to the above-described embodiments, the installation position of the wire can be set through various methods such as a position at which the wire can receive the influence of the occurrence of the landslide as much as possible according to the judgment of an ordinary technician.

The second side (the left side end in the drawing) may be connected to the detection sensors s1, s2, s3, ..., sn respectively. For example, the first-second side of the first wire w1 may be connected to the first conductor of the first sensing sensor S1. And the second-second side of the second wire w2 may be connected to the conductor of the second sensing sensor S2. The n-2-th end of the n-th wire (wn) may be connected to the n-th insulator of the n-th sensor (sn).

In this case, when a landslide occurs in the landslide monitoring area 10, one or more wires w1 to wn may be subjected to a tensile force on the second side (i.e., the left side end) of each wire due to the influence of the landslide . Due to the tensile force, the conductor (s1_126) connected to the second side end electrically conducts each sensing sensor s1. This will be described in detail with reference to FIG.

FIG. 2 is a diagram illustrating a configuration of a sensing sensor according to an embodiment of the present invention. Referring to FIG.

The sensing sensors s1, s2, s3, ..., sn are connected to the wires w1, w2, w3, ..., wn through the conductors 220 as described above. The wirings w1, w2, w3, ... wn have a second side connected to the conductor s1_126 and a first side connected to the landslide monitoring area 10, The wirings w1, w2, w3, ..., wn may be positioned across the landslide monitoring area 10. The wirings w1, w2, w3, ...,

In FIG. 2, the first sensing sensor s1 is illustrated as an example, and the remaining sensing sensors have the same structure.

The first detection sensor s1 is provided with a fixed peg s1_120 having a groove with a predetermined width d1 at the center, and the fixed peg s1_120 includes a header portion S1_122, And a pair of leg portions S1_124 disposed between the grooves.

The pair of leg portions S1_124 are formed with electrical conduction sections s1_125a and s1_125b, respectively. For example, each of the electric conductive parts has a predetermined height d3, and the coil wound on the electric conductive part is preferably wound tightly.

Further, a bottom surface insert portion having a predetermined height d2 is formed below the leg portion s1_124. The topsoil inserting portion may be formed to be sharper toward the lower side so as to be easily embedded in the topsoil.

It is preferable that the fixed peal s1_120 is formed of a nonconductive material.

The conductor s1_126 passes through a groove formed between a pair of leg portions s1_124 of the fixed pot s1_120 and is connected to a wire w1 at one end thereof. An elastic member (s1_127) connected to the fixing point (s1_128), for example, a spring spring is connected to the other side of the conductor

Accordingly, when the tensile force is applied to the wire wn in the right direction in the drawing, the conductor s1_126 moves toward the pair of the electric power passing units s1_125a and s1_125b of the fixed pot s1_120, It is brought into electrical contact with the conductive part, that is, turned on.

When the tensile force of the wire is removed, the conductor s1_126 returns to its original position by the restoring force of the elastic member s1_127.

The conductor s1_126 may have a diameter d4 larger than a predetermined distance d1 of the grooves of the fixing pots s1_120 or may be selectively passed through the conductor s1_126 even if the conductor s1_126 is pulled to the right on the drawing due to a tensile force applied to the wire wn. The conductive member s1_126 is caught without passing through the groove after the conductive member s1_126 contacts the electric conductive units s1_125a and s1_125b.

2, if the contractile force of the elastic member s1_127 in the detection sensor s1 is larger than the tensile force of the wire wn, the conductor s1_126 is spaced apart from the fixed pell s1_120 The pair of electric conduction units s1_125a and s1_125b are disconnected from each other to maintain the OFF state.

At this time, when a debris flow occurs in the landslide monitoring area 10, a force is applied to the wires w1, w2, w3, ..., wn due to the debris flow so that the wire 230 moves the conductor s1_126 in the wire direction .

The attracting force of the wire wn causes the conductor s1_126 to move to the right in Fig. 2 and to electrically contact the pair of electric conduction sections s1_125a and s1_125b of the fixed pot s1_120 of the detection sensor s1 . When the conductor s1_126 comes into electrical contact with the electric conduction units s1_125a and s1_125b, the detection sensor s1 becomes the contact-on state.

If only one sensing sensor s1 is provided, the landslide warning device can also be switched to the power-on state with the sensing sensor turned on. That is, when the landslide warning device maintains the power-off state at the normal time, when the landslide occurs, the electric conductor (s1_126) contacts the pair of the electric power passing sections (s1_125a, s1_125b) of the fixed field (s1_120) And when the pair of electric conduction parts are energized with each other, the detection sensor s1 can be switched to the power-on state while the contact sensor is turned on.

In the case where a plurality of wires are provided and correspondingly a plurality of sensors are provided, no actual landslide occurs, but when an animal is caught on one of the wires to pull the wire, the landslide warning device of the present invention, It can distinguish landslides from landslides.

3, the landslide warning apparatus of the present invention includes two or more wires (w1, w2) and two or more detection sensors (s1, s2) connected to respective wires, And only when two or more detection sensors are all turned on, the information of the landslide occurrence is generated.

3, the conductor s1_126 in the first sensing sensor s1 is in contact with the pair of electrical conduction portions of the fixed electrode s1_120 by overcoming the contracting force of the elastic member by the tensile force of the first wire w1 When the second sensor unit (s2) is turned off so that the second wire (w2) is not pulled in the second sensor unit (s2), the sensor unit Because it is not pulled, it does not judge it as a landslide.

3, the power supply 113 and the two or more detection sensors s1 and s2 are connected in series.

When a group of detection sensors connected in series to each other as described above is referred to as a detection group, although not shown in the drawings, each of the winding groups may be separately connected in parallel so as to distinguish the winding groups in which the wires are drawn.

When all the sensors are in contact with each other in a state where a plurality of sensors are connected in series, the controller 112 connected to the cold sensors generates the landslide occurrence information, and the warning signal generator 114 generates the landslide occurrence information A warning signal such as a siren may be generated according to the occurrence information.

In this case, the landslide occurrence information of the control unit 112 may be notified to the disaster control center through a communication unit 116 connected to the control unit 112 in a wired or wireless manner. That is, the control unit 112 transmits the landslide occurrence information to the external server through the communication unit 116. The external server may be implemented as an operation server located at a remote location from the landslide warning device 100 or the landslide monitoring area 10.

The communication unit 116 may be connected to the external server through a network through a mobile communication network, a PSTN network, or the Internet. Therefore, it is possible to detect the occurrence of landslides and minimize the damage by using existing communication resources that are widely constructed without installing a separate communication infrastructure.

Although not shown in the figure, a separate photographing unit may be provided so that, when the control unit 112 generates the landslide occurrence information, the area may be photographed.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
