Description

Notification System of Slope Movement

The present invention detects the displacement for each unit area for the slope area and transmits the field image along with the result information to the manager terminal in the form of a text message for display, so that the manager can accurately check the site even from a remote location, so that the disaster has occurred It relates to a slope behavior disaster notification system that enables prompt action to be taken accordingly.

The phenomenon of slope failure is also called a landslide, and includes fall, topple, slide, flow, and spread.

In the case of Korea, as the terrain is mountainous, slopes are generated by cutting mountains or hills when road construction or house construction is implemented, and also when dams or embankments are built.

When a slope occurs like this, it is very important to understand the stability of the slope, and it is necessary to take countermeasures by predicting whether there is a possibility of slope collapse in advance.

The causes of slope collapse include internal factors such as geology, soil quality, geological structure, and topographical weakness; natural external factors such as rainfall, snowmelt, groundwater, river and coastal erosion, earthquakes, etc.; It can be divided into artificial extrinsic factors, etc. Due to these factors, when the shear stress increases or the shear strength decreases and the safety factor (= shear strength/shear stress) reaches a state of 1, slope collapse occurs.

In the case of Korea, slope collapse occurs mainly during the intensive rainfall and thawing period in summer, and when the slope collapse occurs, it causes enormous loss of life and property.

Recently, disasters and disasters that are close to natural disasters occur occasionally due to climate change and tectonic fluctuations, such as concentrated heavy rain caused by irregular extreme weather in summer. However, since it is very difficult to predict the collapse of the slope in the event of a disaster or disaster, the situation remains at the level of passive management at the level of establishing countermeasures after slope collapse.

Slopes are broadly divided into natural slopes and artificial slopes. It is very difficult to accurately predict the stability of a slope because the physical properties of the ground vary even on a single slope depending on the depth, weathering degree, deterioration degree, presence and type of geological structure, etc.

For reference, the error of the GPS signal received from each measuring station is corrected using the GPS signal received from a fixed station installed at a fixed location, and the slope behavior is identified and monitored in real time through the Internet or communication network at a remote location. By doing this, it is possible to determine the condition of the slope at that time, to determine whether the slope is safe, and to issue an alarm when a danger occurs to minimize damage to life and property. It has been disclosed in "Method and system for monitoring slope behavior using GPS" of No. 0066218 (published on June 16, 2006).

However, in the case of the prior art described above, since the manager judges the safety of the slope only with the slope behavior data, it is difficult to determine the exact on-site situation and the occurrence of a disaster from a remote location, and the need for an experienced manager to directly visit the site is inconvenient In particular, there is a problem that the scale of the disaster can be expanded as well as casualties due to the delay in the initial action in an actual disaster situation because on-site confirmation of such a manager is required.

It may further include identification information for identifying the location of the device 10 .

The camera 20 photographs the one unit slope area, and transmits the photographed second information to the control server 30 . In this case, the second information may be any one of a moving picture taken in real time and a photo image taken for a predetermined time, or may include both a moving picture and a photo image.

Specifically, the sensing device 10 according to an embodiment of the present invention includes a casing 11 embedded in each unit slope area, as shown in FIG. 2 , and a corresponding unit slope area configured inside the casing 11 . It may be configured to include an inclinometer sensor 12 for measuring the inclination of the casing 11 and a pile 13 that is typed in the ground while passing through the lower surface of the casing 11 .

First, the casing 11 is placed after digging the slope area, and the casing 11 can be buried in the ground by filling the filling material.

The casing 11 allows the electrical components including the inclinometer sensor 12 to be embedded therein to protect the components such as the inclinometer sensor 12 from external forces such as ground subsidence, and to be directly exposed to freezing and thawing. prevent.

In particular, the inclinometer sensor 12 is embedded in the casing 11 to increase the accuracy of the measurement. That is, when the inclinometer sensor 12 is directly exposed to soil, the above-mentioned external force, freeze-thaw, etc. causes a malfunction such as sensor deterioration or increases the probability that an error occurs in the measured value itself. This is to protect the sensor 12 .

In this way, even when an external force acts on the casing 11, the external force is blocked from being directly transmitted to the inclinometer sensor 12 by the above-described configurations, thereby reducing the fatigue of the sensor and controlling the deterioration.

The relaxation of the external force is to buffer the external force in the upper and lower directions by the spring 115-2, and the external force and torsion in the lateral direction are buffered by the rubber ball 114-1. That is, it is possible to protect the inclinometer sensor 12 from external forces in multiple directions by the above configuration.

Here, the horizontality of the horizontal plate 112 in the support 113 can be adjusted so that the horizontality of the horizontal plate 112 can be adjusted by adjusting the bolts in the body 114 as shown in the figure. In addition, by applying a known technique, the horizontality may be automatically adjusted by hydraulic pressure or the like.

In addition, by such a configuration, it is possible to reduce the exposure points to external air such as the above-mentioned freezing and thawing as much as possible.

The inclinometer sensor 12 is connected to the cable 16 embedded in each unit slope area, and as shown in FIG. 5 , the cable 16 penetrates the casing 11 from the lower surface and the inclinometer sensor 12 . to be connected with At this time, for watertightness, a watertight ring (no reference number) should be fastened between the cable 16 and the through hole (no reference number).

The detection sensor 186 is configured on the upper portion of the water level measuring tank 180 to detect electrical contact with the contact member 185 . As mentioned above, as the water level in the water level measuring tank 180 rises, the contact member 185 rises. As a touch signal is generated, the detection sensor 186 is connected to the cable 16 so that the contact signal generated as described above is transmitted through the cable 16 .

If such a contact signal is generated for a certain amount of time, it can be determined that the moisture content corresponds to the risk of collapse at the corresponding point as a critical contact signal.
