BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope advance collision detection system, and more particularly, to a slope collapse advance detection system in which collapse of a slope is detected in advance to prevent a collapse-caused disaster.

Due to the geographical characteristics of mountainous areas and the fact that about two-thirds of the average annual rainfall (1300 ~ 1500mm) is concentrated in the summer season, slope failures frequently occur, resulting in yearly loss of life and property as well as serious economic and social damage. have.

Therefore, in order to prevent slope collapse in advance, slope maintenance system is currently under development in both Korea National Institute of Construction Technology and Road Research Institute of Korea Highway Corporation for cutting slopes of national highways and expressways in Korea. These slope maintenance management systems are commonly developed based on the investigation of the status of slope distribution, slope survey and stability analysis, establishment of countermeasure method, and database construction on slope data.

However, it is necessary to evaluate the long - term stability of the slope through the measurement of the slope of the slope beyond the maintenance stage of the slope through merely slope survey and databaseization, and to establish measures against the instability of the slope.

In particular, by developing a slope automatic measurement system capable of monitoring the slope behavior in real time at a remote location, it is possible to predict and predict the slope failure at a remote place in an early stage to establish appropriate measures against the slope risk and minimize damages caused by slope collapse I need a plan.

In addition, long-term data related to slope behavior can be accurately and efficiently accumulated through an automatic measurement system, and the correlation between slope failure factors (rainfall amount, etc.) and slope failure can be measured, To minimize the damage caused by slope failure and to improve the accuracy of the warning time by actively using the automatic warning system and operating the alarm system by constructing an automatic measuring system on the slope where the collapse is likely to recur or the collapse is in progress. .

Japanese Patent Application Laid-Open No. 2009-0116208 discloses a technique including a main body coupled to one of the files, a displacement measuring sensor provided in the main body, and a settlement amount measuring system installed in the main body to measure the slope settlement amount by relative displacement between the files .

However, the above-mentioned technology has a problem that when the weeds are flooded and the forest is thick, the settlement amount measurement system is not operated smoothly, and the displacement of the slope can not be detected accurately. Even when the slope is not collapsing, There is a problem that a large amount of energy is consumed.

The Utility Model Registration No. 0293128 discloses an image pickup apparatus comprising slope monitoring image acquisition means, slope measurement data collection means, slope surveillance image processing means, slope measurement data processing means, and central control means, To monitor real-time slope.

However, the above-described technique measures the displacement of a slope through a sensor. However, in the case of a sensor, it is difficult to measure a minute displacement, and a large amount of energy is consumed because power is continuously supplied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a slope collapse advance detection system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 8, a plurality of slope disintegration advance detection systems according to an embodiment of the present invention are installed on a slope surface, and sense information is transmitted to the administrator server 40 by sensing a slope of a slope surface, It is possible to promptly detect the collapse of the vehicle and to cope with it immediately.

The slope advance detection system includes a detector 10, a peripheral sensor 20, a field controller 30 and an administrator server 40. The sensor 10 includes a plurality of peripheral sensors 20, And the detector is configured to transmit information of the peripheral sensor connected to the detector to the field controller 30. [

A plurality of detectors 10 are installed on the slope surface, and the tilting of the installation area is sensed and transmitted to the field controller 30. At this time, the detector 10 detects a plurality of peripheral sensors 20 installed irregularly around the sensor 10, and transmits the detection information to the field controller 30.

In the present invention, the detector 10 and the peripheral sensor 20 are provided to be wired, and the detector 10 and the field controller 30 are connected to each other through a network communication network to perform wireless communication.

At this time, the peripheral sensor 20 is configured to perform the electrical contact only when the tilting occurs.

Therefore, when a slope such as slip occurs in a place where the peripheral sensor is installed, electric current flows while the electric contact of the peripheral sensor is connected, so that the sensing unit outputs a contact signal, that is, The risk of slope failure is reported, and the manager recognizes the danger of the slope.

Since the power is supplied only to the detector 10 except for the peripheral sensor 20, it is possible to monitor the collapse of the slope surface with only a small amount of energy compared with the conventional one. It is possible to acquire accurate information without a problem such as a malfunction due to the sensor.

The detector 10 and the ambient sensor 20 according to one embodiment are shown in FIGS. 3 and 4. FIG.

3, the sensor 10 includes a column 11 coupled to the upper end of a column directly buried in a slope surface or installed on a slope surface, and a sensor 11 installed on the column 11 to detect a slope of the slope surface. A controller 13 for transmitting the sensing information sensed by the sensing means 12 and the sensing information of the peripheral sensor 20 to the field controller 30, And a communication module 14 for transmitting the detection information through the communication module 14.

The pillars 11a are fixed to the columns by bolts or the like or fixed to the floor by an anchor or the like to form a flow 11a. The pillars 11a are formed on the lower part of the column 11, .

At this time, the column 11 should be installed in a vertical direction irrespective of a slope of a slope, so that the middle portion of the column is angled to effectively install the column 11. For example, as shown in FIG. 3, the joint portions 11b may be formed so as to be bent in different directions. Therefore, even if the struts 11 are inclined to the ground, they can be vertically installed through the operation of the joints 11b.

It is sufficient that the joints 11b are formed at two positions at intervals of 90 [deg.], But they may be formed at three positions at intervals of 60 [deg.] Depending on the case.

The sensing means 12 may have the same structure as a conventional tilt sensor or a structure for detecting whether a tilt is generated through an electrical contact of a peripheral sensor. In the accompanying drawings, a tilt sensor is used.

The control unit 13 is provided for controlling the detectors and the peripheral sensors and is preferably installed in a separate box on one side of the strut 11 and is provided with a battery 15 The sensing unit 12 and the communication module 14 are also installed in the box and are connected to the control unit in a circuit connection manner.

The battery 15 may be a mercury battery or a dry battery.

As described above, the peripheral sensor 20 is wired to the detector 10 to receive power. When the tilting is not generated, current flow is blocked. When the tilting is generated, The contact is made so that current flows.

Therefore, it is possible to detect whether the inclined slope of the slope installed with the peripheral sensor is generated through the current flow of the peripheral sensor 20.

4, the peripheral sensor 20 may include a strut 21, a case 22, a contact terminal 24, and a weight 25.

The column 21 is coupled to the upper end of a column directly buried in a slope or provided on a slope and may be formed to have the same angle as that of the column 11 of the sensor 10,

Reference numeral 21a denotes a base plate, and reference numeral 21b denotes a joint portion.

The case 22 is coupled to the upper part of the strut 21 and a receiving space 23 in which the contact terminal 24 and the weight 25 can be installed is formed therein.

The case 22 is formed to be transparent or translucent so that light can be transmitted to the outside when the LED lamp 50 emits light when the LED lamp 50 described later is installed.

The case 22 includes a body portion 22a and a cap portion 22b for opening and closing an upper portion and a lower portion of the body portion so as to be separated into three portions for installing the contact terminal 24 and the weight 25. [ And the coupling of the cap portion 22b and the body portion 22a is coupled in a helical manner.

Here, the coupling of the cap portion 22b and the body portion 22a is not limited to the spiral coupling, but may be coupled by the interference fit, the screw coupling, and the coupling by the coupling protrusion.

A plurality of the contact terminals 24 are provided at predetermined intervals along the circumferential direction at the lower edge of the case 22. The weight 25 is connected to the wire rope 26 fixed to the inner upper portion of the case 22, And is installed at the center of the inner side of the contact terminal 24 so as to be spaced apart from the contact terminal 24 so that current flow is interrupted.

Therefore, in the initial installation state in which the tilting does not occur, the current does not flow because the weight 25 is in a state of being spaced from the contact terminal 24. In this state, when the tilting slope is inclined, When the current flows, a current flows through the sensor 10 to detect that the power is supplied, and the detection information is transmitted to the field controller 30 .

The contact terminals 24 are formed of a circular rod or a pin having a predetermined length and are provided in the inner lower edge of the case 20 along the circumferential direction. The contact terminals 24 are connected to each other And are connected to each other by a conductive panel.

The weight 25 is positioned at the center of the inside of the contact terminal 24 while being supported by the wire rope 26. The electric contact is made through contact between the weight 25 and the contact terminal 24, It flows.

At this time, the weight 25 comes into contact with the two contact terminals 24, so that even if a contact failure occurs at a contact point of the spot, the contact is connected at another point to make a current flow.

The on-site controller 30 is installed on one side of a slope surface, and is wired and wirelessly connected to the plurality of detectors 10 installed on the slope surface, and receives the detection information and transmits the detection information to the manager server 40 at a remote site.

The field controller 30 is provided with a communication module for communicating with the manager server 40 through a communication network. Electric power generated through a solar cell or the like is supplied to the electric power supply /

Here, at the one side of the field controller 30, the surroundings of the area where the detectors 10 are installed when the detection information is received from the detector 10 is photographed, and the photographed images are transmitted to the manager server 40 together with the detection information The camera 31 is installed. The camera 31 may be installed on the top of the field controller 30 or may be provided on a support provided with a support and provided for mounting the solar cell.

Meanwhile, the peripheral sensor 20 may be provided with an LED lamp 50 which is supplied with power when the weight 25 contacts the contact terminal 24.

The reason why the LED lamp 50 is installed is that a plurality of the peripheral sensors 20 are installed in the periphery of one sensor 10 so that when the contacts are connected, It is possible for the administrator to easily confirm whether the contact is connected or not in a shorter time with the image taken by the camera 31.

Even if the LED lamp 50 is not installed, all the surrounding sensors 20 are stored in advance in the respective detectors so that the surrounding sensors connected to the contacts are detected during connection of the contacts, .

At this time, an alarm is installed in the field controller 30 so that an alarm is sounded when the LED lamp 50 emits light, thereby informing the passer who is passing nearby that collapse is present, thereby reducing the damage caused by sudden collapse It is possible.

Reference numeral 51 denotes an anode wire, reference numeral 52 denotes a cathode wire, reference numeral 52a denotes a first cathode wire, and reference numeral 52b denotes a second cathode wire.

In the slope failure detection system of the present invention configured as described above, when slope motion occurs due to collapse of a slope in a state where the slope is installed on the slope, the sensor 10 and the surrounding sensor 20 move along with the movement of the slope. 7, when the weight 25 is tilted in either direction, the weight 25 is moved to contact the contact terminal 24, and at the same time, the electrical contact is connected to the first negative electrode wire 52a, And the second cathode wire 52b are connected to each other to allow a current to flow. The sensor 10 senses the presence or absence of contact of the peripheral sensor and transmits the sensing information to the field controller 30.

Therefore, when there is no sign of collapse of the slope, unnecessary energy waste can be reduced because the power supply is cut off because the contact is broken. In addition, when the tilting occurs, the electrical contact is tilted in response to the tilting, There is a predictable advantage.
