Description

Disaster Management Surveillance System for All Dams {DISASTER MANAGEMENT SURVEILLANCE SYSTEM FOR EROSION CONTROL DAM}

The present invention relates to a disaster management monitoring system for all four dams to monitor the soil flow flowing into the four dams of the valley and to issue an early warning. More specifically, the present invention can be easily installed and maintained regardless of the geographical condition of the valley. It also relates to a disaster management monitoring system on all sides of the dam that minimizes damages downstream by early warning of overflow and landslides.

Rocky Mud Fow refers to a phenomenon in which soil or stone flows with water, and when a large amount of soil flows from a mountain suddenly along a valley due to rainfall or torrential rain, it appears as a massive destructive force downstream. Causes sacrifice In addition, the soils, which are not landslides caused by landslides, are also damaged by the sediments at the bottom of the valleys.

In order to prevent the damage caused by these soils, four-sided dams are installed that block the soils across the valley. The four-side dam has a structure that prevents the incoming soil from flowing downstream while the valley water flows downstream, so that the soil generated by rainfall or heavy rain accumulates on the upstream walls of the four-side dam. Therefore, the amount of sediment accumulated by the four sides of the dam can measure the amount of soil that can be blocked by the four sides of the dam.

However, if you look at the conventionally installed four-way dam, you do not monitor the amount of sediment deposition, you have to go directly to the situation of the four-side dam, and in addition, it is difficult to visit the four-side dam when rainfall or heavy rain occurs, It could not be confirmed, and it was difficult to grasp the ability to block the soil by the four sides dam.

On the other hand, as a conventional technology for monitoring the soil of the valley, there was a registered patent No. 10-0814470 and Patent Publication No. 10-2010-0053830, and the prior art to install the wire across the valley to monitor the disconnection of the wire. The occurrence of earth and sand was detected by using a light emitting unit and a light receiving unit in the valley to monitor the disconnection of the light source, to monitor the behavior of the soil layer, and to monitor the slope of the soil layer. However, the soil detection means adopted in the above-described prior art is difficult to install due to the geographic conditions of the valley, and had to be repaired every time the soil was generated.

Moreover, the above-described conventional techniques are not enough to cause damage to downstream, but when the soil is continuously piled up in the valley, the amount of accumulated soil can not be accurately grasped, and may be caused by the soil accumulated in the valley during heavy rains. It was not possible to predict the amount of clays present.

In addition, since the soil is generated in a state in which the soil is mixed with the valley water, estimating the amount of the soil alone except the valley water in the soil may predict the situation of the valley and the disasters that may occur in the future. Essen made no mention of this.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or known configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a four-way dam disaster management monitoring system according to an embodiment of the present invention, Figures 2 to 5 are views showing the installation position of the components of the four-way dam disaster management monitoring system. Specifically, Figure 2 is a landscape diagram around the four dams showing the installation location of the four-side dam monitoring unit 10 and the valley monitoring unit 20, Figure 3 is an upstream side to show the installation position of the four-side dam monitoring unit 10 4 is a cross-sectional view of the pressure sensing unit 220 installed on the four sides dam, and FIG. 5 is a cutaway view of the valley showing the components of the valley monitoring unit 20.

1 to 5, the four-way dam disaster management monitoring system according to an embodiment of the present invention, measuring and transmitting the amount of sediment deposited on the upstream side wall of the four-side dam (1) installed across the valley Four sides dam monitoring unit (10); Valley monitoring unit 20 is installed in the upstream valley at a distance from the four sides dam (1) to measure and transmit the amount of soil accumulated in the valley; Management server 30 for collecting and monitoring the soil sediment accumulation information of the four sides dams and valleys, and issues a warning according to the monitoring result; Manager terminal 40 for receiving the warning issued by the management server 30; .

Here, it should be noted that the amount of sediment measured is the amount of sediment only when the number of valleys is weak, and the amount of sediments when the soil is mixed with the number of valleys occurs. It should be noted that this is either the amount of soil or the amount of soil. In addition, since the soil flows along the valley, the sediment amount measured by the four-side dam monitoring unit 10 and the valley monitoring unit 20 is measured as the amount of the soil moving to the upper portion of the measurement point.

The four-side dam monitoring unit 10 is installed on the upstream side wall of the four-side dam (1), the four-sided dam deposition amount sensing means for measuring the amount of sediment accumulated in the block piled up by the four-side dam (1), And a main data logger 100 for transmitting the accumulation amount information of the soil obtained by measurement to the management server 30.

The four-side dam sediment sensing unit 200, the image sensing unit 210 for measuring the sediment height by measuring the amount of sediment and the pressure applied by the load of sediment accumulated per unit area to measure the amount of sediment It is composed of a pressure sensing unit 220.

The image sensing unit 210 installs a tape measure 211 having a vertically extending scale up and down on the upstream side wall of the four-side dam 1, and shoots the tape measure 211 with the camera 212, thereby taking a tape measure 211. The scale position at the bottom of the image shown in the) is configured to detect the height of sediment deposition. The camera 212 allows the surrounding dam and the four-sided dam to fall within the shooting range, so that the resident manager can see the four-sided dam and the surroundings as the image is displayed by the management server 30 to be described later.

The pressure sensing unit 220 is installed on the upstream side wall of the four-side dam (1) to sense the pressure applied to the wall surface. It should be noted that in the case of a fluid, the pressure at the same depth is the same regardless of the direction, but in the case of soil (or soil), there is a difference between the pressure applied in the vertical direction and the pressure applied in the horizontal direction, In addition, since the installation of the four-sided dam (1) in a valley with a high inclination is applied to the accumulated soil load in the inclined direction, the pressure sensed by the pressure sensing unit 220 and the pressure applied in the vertical direction by the Causes a difference. Therefore, the pressure measured by the pressure sensing unit 220 is preferably converted to the pressure in the vertical direction according to the stacking height of the soil, the conversion equation is the inclination angle of the upstream side wall of the four-side dam (1), the slope of the valley And it is good to determine in advance according to the type of soil deposited in the valley. For example, the conversion relation may be formed by multiplying the pressure (that is, the weight) measured by the pressure sensing unit 220 with a ratio determined in consideration of the above considerations.

On the other hand, since the pressure sensed by the pressure sensing unit 220 means the pressure applied to the four-side dam (1), it is also to monitor the possibility of collapse of the four-side dam (1) by monitoring the pressure value before converting into a vertical load good. In addition, as shown in FIG. 3, the pressure sensing unit 220 may be installed in plural numbers on the upstream side wall of the four-side dam 1.

The pressure sensing unit 220 may employ a well-known load cell for detecting pressure (ie, weight or load), but in the embodiment of the present invention, since the amount of impact when the actual soil flows in is very large, In consideration of the simple structure. Referring to FIG. 4, the pressure sensing unit 220 protrudes outward from the wall surface of the four-side dam 1 and the fixing body 221 embedded in the wall surface of the four-side dam 1, and is movable toward the fixing body 221. A moving body 222, a compression spring 223 interposed between the fixed body 221 and the mobile body 222, and a distance sensing installed in the fixed body 221 to sense the distance to the mobile body 222 It comprises a sensor 224. As the pressure sensing unit 220 is configured as described above, the compression spring 223 compresses when the moving body 222 is pressed against the soil and moves toward the fixed body 221. The size of the elastic force can be obtained as the moving distance of the moving body 222, which is based on the characteristic curve of the elastic force with respect to the compression displacement of the compression spring 223.

Here, since the soil flows not only to accumulate soil on the upstream side wall of the four-side dam 1, the moving body 222 protrudes outside the wall surface of the four-side dam 1 in order to prevent water from penetrating into the pressure sensing unit 220. It is preferable to cover with a flexible protective cover (225). In addition, the compression spring 223 has an elastic characteristic sufficiently to withstand the impact caused by the earth and sand, and the fixing body 221 is also embedded in the wall surface of the four-side dam (1) to the depth of the compression spring 223 Do not reach the elastic limit.

The main data logger 100 transmits the sediment height and sediment weight (pressure according to the sediment) detected by the four-side dam sediment amount sensing means 200 to the management server 30 as sediment amount information. In this case, the image captured by the camera 212 of the image sensing unit 210 is also transmitted to the management server 30. Here, in general, since the four sides dam 1 is installed in a deep valley, it is preferable to transmit information between the main data logger 100 and the management server 30 by using a wireless communication network. In addition, the main data logger 100 also relays the accumulation amount information in the valley received from the valley monitoring unit 20 and transmits it to the management server 30. As described above, the main data logger 100 generates the pressure detected by the pressure sensing unit 220 based on a conversion equation when generating the deposition amount information based on the pressure.

On the other hand, the main data logger 100 is connected to the power supply means 110 because it needs to be supplied with electricity. Since the power supply unit 110 is difficult to receive electricity from the outside due to the geographical condition of the valley, the power supply means consisting of solar cells and wind power generators and charging means for charging the electricity so that the electricity can be stably supplied at all times of weather changes. It is good to have.

The valley monitoring unit 20 is installed in an upstream valley spaced at a sufficient distance (for example, 500 M) from the four-side dam 1 where the four-side dam monitoring unit 10 is installed, and the amount of soil accumulated in the installed point. Is measured, and the information on the measured accumulation amount is transmitted to the four-side dam monitoring unit (10). The valley monitoring unit 20 for this purpose, the sub data logger 300 for transmitting the sediment accumulation amount sensing means 400 and sediment amount information for measuring the sediment amount of the soil deposited in the valley to the four-side dam monitoring unit 10. And a power supply means 310 for supplying power.

In the exemplary embodiment of the present invention, the valley deposition amount sensing means 400 is applied by the image sensing unit 410 and the accumulated soil which senses the deposition height of the soil in the same manner as the above-described four-side dam deposition amount sensing means 200. It is configured to include a pressure sensing unit 420 for sensing a load.

However, the image sensing unit 410 here consists of a camera 412 that shoots the rod 411 by planting the lower portion of the rod 411, which is engraved with a scale in a valley, and standing vertically, which is engraved with a scale. Because there is no place to put a tape measure. The camera 412 is not only photographing the rod 411, but the entire valley portion in which the rod 411 is installed as a photographing range, so that the manager who resides in the situation of the valley in the management server 30 to be described later can be seen. To be.

In addition, the pressure sensing unit 420 is embedded in the valley and detects the amount of soil accumulated in the upper portion by weight. In detail, referring to FIG. 5, the pressure sensing unit 420 is a hollow tube-shaped embedded body 426 deeply embedded in a valley embedded in a valley, and a fixing body inserted into and fixed to the upper opening of the embedded body 426 ( 421, the movable body 422 which can descend toward the stationary body 421, the compression spring 324 interposed between the stationary body 421 and the movable body 422, and the stationary body 421 are installed to move the body ( And a flexible protective cover 425 covering the movable body 422 so that water does not enter the fixed body 421. Here, the filling body 426 is deeply planted in the valley and the fixing body 421 is installed so as not to be swept away by the soil. In addition, it is preferable that the pressure sensing unit 420 is embedded in a plurality of pieces, since the exact value can not be obtained by measuring the amount of sediment deposition at only one point of the valley. In addition, it is preferable to bury a plurality of pressure sensing unit 420 to be arranged in the direction across the valley, to calculate the earth flow flowing along the valley, in this case, the rod 411 in the embodiment of the present invention Although only one is shown, it is better to provide a plurality of the installation in a direction crossing the valley.

On the other hand, referring to Figure 5, the pressure sensing unit 420 is attached to the inclination sensing unit 500 for detecting the inclination, when the landslide occurs and the pressure sensing unit 420 is inclined to detect the sub data logger Send a signal to 300. This is because, when a landslide occurs, the ground of the depth in which the pressure sensing unit 420 is embedded can also be moved downstream. The inclination sensing unit 500 may be configured as, for example, an acceleration sensor.

The sub data logger 300 is electrically connected to the valley accumulation amount sensing means 400 and stores the accumulation amount information measured by the valley accumulation amount sensing means 400 as the main data logger of the four-side dam monitoring unit 10. To 100. That is, the sub data logger 300 reads the position of the scale shown in the image of the rod 411 engraved with the scale, obtains the accumulated height of the soil, and accumulates the soil with the pressure detected by the pressure sensing unit 420. By acquiring the weight, the amount of accumulation information based on the deposition height based on the photographed image and the amount of accumulation information based on the pressure are transmitted to the main data logger 100 together with the image. Here, it is preferable that the data transmission between the sub data logger 300 and the main data logger 100 is made by a short range wireless communication technology.

The power supply means 310, like the power supply means 110 of the four-side dam monitoring unit 10, because it is difficult to receive electricity from the outside in the geographic conditions of the valley, so that the electricity can be stably supplied at all times in the weather changes It is preferable to have a power generation means consisting of a battery and a wind power generator and a charging means for charging electricity.

The manager terminal 40 receives alarm command information from the management server 30 as a manager's portable terminal. The manager terminal 40 is a mobile communication terminal used by the manager, for example, a mobile phone, a PDA, a smart phone, a tablet, and receives alarm command information transmitted from the management server 30 in a text message or a video. In the case of a smart phone or tablet, it is preferable to utilize a dedicated application that can conveniently check the alarm command information transmitted from the management server (30).

The management server 30 receives and monitors the deposition amount information from the four-side dam monitoring unit 10, and when the deposition amount reaches a preset threshold in the process of monitoring the deposition amount information, or the amount of change in the deposition amount per hour. A warning is issued when the preset threshold variation value is reached. In this case, the monitoring means monitoring the change in the amount of sediment information over time and calculating the amount of change in the amount of sediment, thereby monitoring the amount of change in the hour, and the amount of change of the sediment information and the amount of sediment on the display unit (not shown). It means to print out and display visual information to resident administrator. In addition, the monitoring means outputs the camera image received from the four-way dam monitoring unit 10 to the display means that the resident manager to monitor the situation of the four-way dam and valley as an image.

In addition, the warning issued by the management server 30 is usually a green warning light, but when the amount of accumulated soil is increased, a yellow warning light and a red warning light are lighted step by step or an alarm broadcast is issued, and a warning message is output to the display unit. It can adopt what it does.

In addition, the warning is that the management server 30 transmits the warning content to the administrator terminal 40 to notify the administrator does not reside in the monitoring center in which the management server 30 is installed. Here, the contents of the warning issued to the manager terminal 40 may be made of a text message or a video of the dam or the valley indicating the warning.

In addition, the four-way dam disaster management monitoring system according to the present invention is further provided with a warning plate on the downstream side of the four-side dam, it is preferable to inform the warning issued situation to people living or moving downstream.

In addition, the management server 30 receives the sediment accumulation amount information accumulated on the four sides of the dam and the sediment accumulation information on the upstream side of the four sides of the dam to monitor the four sides of the dam and the upstream valleys, respectively, It also monitors the impact on the sediment volume of the four dams. In other words, if the amount of sedimentation in the four-sided dam increases over time when the amount of sedimentation (in this case, the amount of sediments) increases rapidly in the upstream valley, the elapsed time is sensed as the movement time of the sediment. Accordingly, the management server 30 can predict the time when the soil flows upstream of the valley reaches the four sides of the dam and the amount of soil piled up on the four sides of the dam, and also predicts the time of overflow of the soils. It is.

On the other hand, it is preferable that the management server 30 monitors the movement time and the movement amount before the soil flow moving along the valley reaches the four-side dam, so as to predict the timing of the overflow in advance. To this end, the valley monitoring unit 20 may be installed at a plurality of points on the upstream side of the four-side dam, but may be installed at a distance from each other along the valley. In other words, using the time difference between the increase in the amount of soil in the valley monitoring unit installed upstream and the increase in the amount of soil in the valley monitoring unit installed downstream, it is possible to estimate the moving speed of the soil and detect the amount of the amount of soil detected upstream and downstream. It compares mutually and predicts the amount of movement of the soil, and based on the movement speed movement, it is possible to predict the time of reaching the four sides dam and the amount of the soils reaching the four sides dam.

In the present invention, since the deposition height and the pressure according to the deposition are obtained at the point where the tape measure (or rod) is installed and the pressure sensing part is installed, the valley monitoring unit 20 and the four-side dam monitoring unit 10 are deposited at the position where the installation unit is installed. Although it is difficult to calculate the total amount accurately, the values obtained from the point where the tape measure (or rod) is installed and the pressure sensing part are installed. ), And the depth of the valley can be predicted.

In addition, the deposition amount information monitored by the management server 30, the accumulation amount information based on the pressure (or weight) by the accumulated soil and the accumulation amount information based on the accumulation height of the accumulated soil, both of the deposition amount information Since the basis of is different, it can be obtained with different values, and furthermore, there is an error from the actual deposition amount. This is because the density of the soil can not be specified in advance by precisely matching the density of the soil to the actual situation, and also because the valley water may flow in the gap of the soil or the top of the stacked soil. Accordingly, the scale shown in the image of the camera may not detect the exact deposition height of the soil alone according to the influence of the valley water, and the pressure detected by the pressure sensing unit may not detect the weight of the soil alone according to the influence of the valley water. In other words, the pressure and height measured by the sedimentation amount information may be values due to accumulated soil, valley water flowing through the stacked soil, or flowing as soil.

Accordingly, the management server 30 according to an embodiment of the present invention calculates the water level based on the deposition amount information based on the pressure of the pressure sensing unit and the sediment layer height based on the scale in the captured image, and corresponds to the calculated water level. It is configured to obtain the amount of sediment accumulation information except pressure.

As a specific embodiment, the management server 30 is configured to pre-specify the specific gravity (density) of the soil according to the geological characteristics of the valley, and also to specify the specific gravity of the valley number in advance, which is transmitted from the four sides dam monitoring unit 10 After converting the pressure value into the deposition height, the deposition height based on the pressure and the deposition height received from the four-side dam monitoring unit 10 are compared with each other. As a result of the comparison, if it is out of the predetermined tolerance, it is judged as an error due to the number of valleys, and the amount of sediment deposition is calculated based on the following simultaneous equation.
