Description

[0001] SENSING SYSTEM FOR COLLAPSE OF SLOPE [0002]

The present invention relates to a slope failure detection system. More particularly, the present invention relates to a method of measuring the surface behavior of a slope using an elastic force of an elastic support by mounting an indicator displacement detection module on an upper portion of an elastic support that is exposed to the top of a slope of a slope, Particularly, it is possible to prevent the malfunction of the sensor due to the external load so that the possibility of collapse of the slope face can be accurately predicted. In addition to the measurement value of the surface displacement detection module by mounting a separate ground displacement detection module in the foundation block embedded in the soil layer The present invention relates to a slope failure detection system capable of predicting the ground motion of a slope surface in consideration of all the measured values of the ground displacement detection module, thereby enabling more accurate collapse prediction.

Generally, the slope surface is formed by an artificial cut or embankment or is formed by a natural settlement. When the slope surface is weakened, it causes great loss of life and material damage.

Particularly, the slope of the slope is often caused by the geographical characteristics of the mountainous region and the climate characteristic of the winter season where about two-thirds of the average annual rainfall (1300 ~ 1500mm) is concentrated in Korea. This causes yearly loss of people and property, .

In order to prevent collapse of the slope, a physical construction technique such as a net, a partition, and a concrete installation method has been used. However, such a construction method has a problem that the slope can not be sufficiently collapsed.

Recently, a method for predicting the collapse of the slope and predicting the slope has been actively researched and developed. As a countermeasure to prevent the collapse of the slope in advance, slope maintenance system is currently being developed in Korea by Korea Institute of Construction Technology and Road Traffic Research Institute of Korea Highway Corporation for slope slope of general highway and expressway in Korea. The system is commonly developed based on the investigation of current slope distribution, slope survey and stability analysis, establishment of countermeasure method, and database construction on slope data.

A slope failure detection system for predicting the slope failure of a slope surface is a widely used method for predicting the collapse of a slope by measuring a strain of a wire in real time by connecting a plurality of files to a slope and connecting the upper portion of each file with a wire have.

However, this slope failure detection system has a problem that it is impossible to precisely predict the possibility of the slope collapse because only the change of the slope surface can be observed, but the change of the slope surface can not be detected at all.

Particularly, slope slopes are generally formed by forming a rock layer on a deep depth layer, and a slope layer on top of a rock layer. The slope collapse occurs in a form in which the slope layer collapses. Therefore, it is desirable to estimate the slope failure probability by measuring the ground slope change as well as the ground slope change, thereby further improving the prediction accuracy. Therefore, there is a strong demand for a detection system capable of detecting such slope change.

Also, in the case of a file installed externally on the slope surface, the file may be changed due to collision of live beasts or by external factors such as wind or trees, and the change of the actual slope surface can not be accurately detected .

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a conceptual view of a slope failure detection system according to an embodiment of the present invention. FIG. 2 is a block diagram illustrating a configuration of a surface displacement detection module of a slope failure detection system according to an embodiment of the present invention. FIG. 3 is a view illustrating an example of an elastic deformation state of an elastic support of a sloping surface collapse detection system according to an embodiment of the present invention. Referring to FIG.

The slope failure detection system according to an embodiment of the present invention includes a base block 100, an elastic support 200, an indicator displacement detection module 300, a repeater 400, and a central control unit 500 .

The foundation block 100 is buried in the soil layer 12 of the slope 10 and may be formed in the form of a concrete block or in the form of a separate box-like structure. As shown in FIG. 1, slope 10 is formed in such a manner that a rock layer 11 exists in a deep layer and a tolstone layer 12 is stacked on an upper portion of rock layer 11. Slope collapse generally occurs when the slope of soil layer 12 It is caused by collapse. The foundation block 100 is embedded and fixed to the soil layer 12, not the rock layer 11, so that the behavior of the soil layer 12 can be detected.

The lower end of the elastic support 200 is coupled to the foundation block 100 and the upper end of the elastic support 200 is exposed on the upper surface of the ground surface. Respectively.

The surface displacement detection module 300 is coupled to the upper portion of the elastic support 200 to configure different measured values according to the displacement state of the elastic support 200. That is, it is configured to measure the displacement state of the elastic support 200.

For example, the surface displacement detection module 300 includes an index case 310 fixedly coupled to an upper portion of the elastic support 200, and an inclination angle sensor 360 installed in the index case 310 to measure an inclination angle of the index case 310 An electronic compass 330 mounted on the inside of the indicator case 310 to measure the inclination direction of the indicator case 310 and an indicator case 310 mounted inside the indicator case 310, And an accelerometer 340 for measuring the moving state of the vehicle.

The inclination meter 320, the electronic compass 330 and the accelerometer 340 measure the displacement of the indicator case 310 within the indicator case 310. The displacement of the indicator case 310 is measured by the displacement of the elastic support 200 The displacement of the indicator case 310 can be measured by measuring the displacement of the elastic support 200. [ Since the lower portion of the elastic support 200 is coupled to the foundation block 100 and buried in the soil layer 12, the soil layer 12 of the slope surface 10 is moved over a predetermined reference value as a precursor of collapse The displacement of the resilient support 200 due to the movement of the soil layer 12 will occur and thus the measurement value of the sensors of the surface displacement detection module 300 will be referred to as measuring the moving state of the soil layer 12 .

The indicator case 310 may include a display unit 350 that displays values measured by sensors such as an inclinometer 320, an electronic compass 330, and an accelerometer 340, A separate solar panel 600 may be coupled to one side of the indicator case 310 so as to supply power to the indicator case 310.

The repeater 400 receives the measured values from the surface displacement detection module 300 and transmits the measured values to the central control unit 500. That is, as shown in FIG. 1, a plurality of base blocks 100, an elastic support 200, and an indicator displacement detection module 300 are installed on the slope 10, and the relay 400 includes a plurality of index displacement detection Module 300, and transmits the measured values to the central control unit 500 again. Data transmission between the repeater 400 and the surface displacement sensing module 300 can be set according to the user's need to be performed wirelessly or in a wired manner and data transmission between the repeater 400 and the central control unit 500 can be performed according to the transmission distance It is preferable that it is performed in a wireless manner.

The central control unit 500 receives the measurement value measured by the sensors of the surface displacement sensing module 300 from the relay 400 and determines the displacement state of the slope 10 and outputs the determination result.

The sensors of the surface displacement detection module 300 are mounted on the inside of the indicator case 310 and the displacements of the elastic support 200 and the indicator case 310, The central control unit 500 receives the measured values and calculates them according to a predetermined rule to determine the displacement state of the soil layer 12 .

At this time, since the elastic support 200 coupled to the base block 100 and exposed to the upper surface of the ground surface is elastically deformable, it is elastically deformed and deforms easily even when the soil layer 12 is finely moved. The detection performance for the displacement state of the soil layer 12 of the fuel tank 300 is further improved.

In addition, since the elastic support 200 is formed of an elastic material, when the elastic support 200 is deformed due to a collision of live animals or an external load such as a wind or a tree as shown in FIG. 3, If it is removed, it is restored to its original state by the elastic force. Thus, it is possible to prevent such a malfunction by determining whether the measured value measured by the sensors of the surface displacement detection module 300 is restored after a predetermined time. That is, if the measured values of the surface displacement detection module 300 are all returned to the original state after the elapse of the reference time, the central control unit 500 outputs a collapse warning signal or the like since it is not a measured value according to the displacement of the soil layer 12 It is not necessary to merely output the current state of the slope 10 at the present time. If the measured values remain unchanged even after the reference time has elapsed, Therefore, in this case, a collapse warning signal or the like can be output.

According to such a structure, the slope surface collapse detection system according to an embodiment of the present invention can exhibit a more accurate detection performance for the slope collapse and can prevent the malfunction of the sensor due to external factors.

FIG. 4 is a conceptual view of a slope failure detection system according to another embodiment of the present invention. FIG. 5 is a functional block diagram of a slope failure detection system according to another embodiment of the present invention. 6 is a functional block diagram of the slope failure detecting system according to another embodiment of the present invention, FIG. 6 and FIG. 7 illustrate an operation state of the slope failure detecting system according to another embodiment of the present invention, In which the moving resistance member is mounted.

4 and 5, the slope failure detecting system according to another embodiment of the present invention includes a ground displacement detection module 700 mounted inside a foundation block 100 buried in a soil layer 12 And the like.

The underground displacement detection module 700 is configured to display different measured values according to the displacement state of the foundation block 100. For example, the underground displacement detection module 700 includes an underground case 710 fixedly coupled to the inside of the foundation block 100, And an accelerometer 720 installed inside the underground case 710 and measuring the moving state of the underground case 710. [ Also, although not shown, an inclination meter and an electronic compass can be provided to measure the inclination angle and the inclination direction of the underground case 710, as in the case of the surface displacement detection module 300.

At this time, a wire C connected to the underground displacement detection module 700 is inserted into the inner space of the elastic support 200 and extends to the inner space of the indicator case 310, and the underground displacement detection module 700 is connected to the elastic support 200 may be connected to the solar panel 600 directly or through the indicator displacement sensing module 300 to receive power from the solar panel 600. [ With this configuration, the installation work for the underground displacement detection module 700 can be easily performed.

The repeater 400 is connected to the underground displacement detection module 700 so as to receive the measurement value of the underground displacement detection module 700 and to transmit the measured value to the central control unit 500. The central control unit 500 is connected to the surface displacement detection module 300 and the ground displacement detection module 700 to determine the displacement state of the slope 10.

More specifically, when the measured value transmitted from the surface displacement detection module 300 is equal to or greater than a predetermined first reference value, the central control unit 500 determines whether the measured value transmitted from the underground displacement detection module 700 is a second reference value If the measured value of the underground displacement detection module 700 is equal to or greater than the second reference value, it is possible to determine the displacement state of the slope 10 and output a collapse warning signal.

For example, as described above, since the elastic support 200 can be elastically deformed, when the elastic support 200 is deformed due to the external load, it returns to the original shape after a predetermined time elapses. However, The central control unit 500 judges that the displacement of the soil layer 12 has occurred, and the central control unit 500 judges that the displacement of the soil layer 12 has occurred when the elastic support 200 is maintained in a deformed state without returning to the original state And output a collapse warning signal. This indicates that the deformation caused by the external load was not detected and that a false warning signal was output.

In one embodiment of the present invention, the underground displacement detection module 700 is installed in the foundation block 100 buried in the earth layer 12 to determine the displacement state of the foundation block 100 and the underground case 710, , The displacement state of the soil layer 12 is measured and it is possible to judge whether or not the displacement of the soil layer 12 has occurred over a certain strength through the measurement value of the underground displacement detection module 700. Based on the judgment result By outputting a collapse warning signal, it is possible to prevent an erroneous warning signal caused by an external load, and thus, a more accurate collapse probability prediction is possible.

At this time, the underground displacement detection module 700 includes only an accelerometer 720 without an inclinometer and an electronic compass to measure only the movement of the to-earth layer 12, and the inclination angle and the change in the inclination direction are measured by an inclinometer 320 and the electronic compass 330, the configuration of the system can be simplified.

That is, when the measured value of the surface displacement detection module 300 is maintained to be equal to or greater than a predetermined first reference value, the central control unit 500 does not directly determine that the measured value is due to the soil layer displacement, If the second reference value is equal to or greater than the second reference value, it determines a tolvalue displacement using the measured value of the surface displacement detection module 300, and outputs a collapse warning signal. Since only the information about whether or not the displacement of the soil layer 12 has occurred over a predetermined reference is sufficient, the measured value through the underground displacement detection module 700 can include only the accelerometer 720, The inclination angle and direction change of the slope surface 10 can be determined using the slope meter 320 and the electronic compass 330 of the surface displacement detection module 300.

7 (a), when the inclination angle of the foundation block 100 changes due to the displacement of the soil layer 12, and the elastic support 200 is deformed accordingly, the elastic support The inclination angle, the inclination direction, and the like of the soil layer 12 can be measured by the land surface displacement detection module 300 mounted on the upper part of the bed. Whether the measured value of the surface displacement sensing module 300 is actually due to the displacement of the soil layer 12 can be determined through the measured value of the underground displacement sensing module 700, that is, the measured value of the accelerometer 720 have.

7 (b), when the soil layer 12 flows downward along the inclined direction as it is, the elastic support 200 can be moved downward together with the foundation block 100 without being deformed The measured values by the inclinometer 320 and the electronic compass 330 of the surface displacement sensing module 300 are not changed and only the measured values of the accelerometer 340 of the surface displacement sensing module 300 are changed . At this time, it can be known through the measured value of the accelerometer 720 of the underground displacement detection module 700 that displacement has occurred in the soil layer 12, and accordingly, a collapse warning signal can be output. That is, even if there is a displacement that does not change in the inclination angle and direction of the soil layer 12, it is possible to detect the displacement and output an accurate collapse warning signal.

According to an embodiment of the present invention, a movable resistive member 800 having a surface in a direction perpendicular to the slanting direction of the slant surface 10 may be mounted on the slanting surface of the elastic support 200, (800) may be formed to have a plurality of resistance plates (810) in a radial direction from the elastic support (200).

Resistance against the movement of the soil layer 12 is generated by the moving resistance member 800 when the soil layer 12 is moved according to such a structure, so that the foundation block 100 and the elastic support 200 are sandwiched between the soil layer 12, So that both the surface displacement sensing module 300 and the underground displacement sensing module 700 can exhibit more sensitive and accurate sensing performance.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
