Recently, domestic river banks have become less stable as river structures due to aging and abnormal floods, and the damage of lives and property due to bank collapse in floods has been increasing. According to statistical data from 1987 to 2003, domestic embankment decay type was 300 monthly (39.6%), erosion 295 (38.9%), erosion instability 87 (11.5%), and destruction by structures. 76 cases (10.0%) are reported. (Korea Institute of Construction Technology, 2004) Monthly flow occurs when flood capacity exceeds the channel's capacity, or when the capacity is lowered by soil or driftwood. Excessive flow velocity and convection force are applied at the part, and it occurs when the bank slope or the bottom part is scoured. Body instability refers to poor fill material and piping due to body and ground leakage. Collapse due to river structure is when the bank cross-section collapses and the bank breaks down or the structure contact surface is made of dikes and foreign materials. And collapse.

Nevertheless, the design standards for river structures in Korea are much lower than those in the US, Japan, and Europe in terms of stability and rationality. Recently, the collapse of river structures related to geotechnical engineering has become a major problem that accounts for 20.5% of the total structure damage. In particular, it has the collective characteristics of element technology related to civil engineering, including water resources related to river structures, piping related to surrounding ground, compaction, ground related to settlement, and structural areas related to drainage box design. Due to the simplicity of the structure, while all the fields of civil engineering are related from the technical point of view, the damage caused by the collapse of the domestic river structure has been increased. Japan has already established a database of facilities overview, location, engineering characteristics, damage history, and soil characteristics in relation to structures and drainage gates.In addition, it is possible to detect cavities around river structures, the largest vulnerability of river structures. It is a situation that proposed a structure / maintenance drainage gate system considering the communication system and ground subsidence.

Suggest.

Hereinafter, a river structure displacement real-time monitoring system according to the present invention will be described with reference to the accompanying drawings.

First, the cause of the displacement of the river structure will be described with reference to FIG. 1. As shown in FIG. 1A, when the river structure is designed according to the river, the river penetrates into the river structure due to the poor soil material and leaks occur. This occurs, and the sedimentation of the foundation of the river structure proceeds, causing the river structure to fall and collapse. In addition, as shown in B of Figure 1, due to the change in the flow rate of the river due to rainfall, such as erosion of the river due to the erosion slope of the river structure or the bottom end of the river structure scour occurs in the river structure as the river erosion stronger river structure Not only does it cause displacement, but also the progressive collapse of river structures. Furthermore, as illustrated in FIG. 1C, when the overflow occurs due to a decrease in water flow due to soil or driftwood and a flood outflow exceeding the water flow capacity, the stream structure collapses due to the overflow. Due to these reasons, when the collapse of a river structure starts, the river structure inevitably carries displacement.

 In view of the point that the displacement of the river structure changes when the collapse of the above-described river structure starts, the present invention, as shown in Figure 2, the step of partitioning and setting the predicted weak portion of the river structure, the river in the weak portion of the river structure And providing measuring means for outputting the displacement information of the structure in real time, collecting and transmitting the displacement information, collecting and receiving the displacement information, and monitoring the risk of displacement in real time.

Predicting, partitioning and setting the fragile portion of the river structure, as described above, grasps both the hydrological and geotechnical causes, analyzes and predicts the statistical data on the occurrence of the problem of the displacement of the river structure so far, By predicting the vulnerable part according to the river structure and dividing the vulnerable part, a system for preventing displacement of the river structure for each region or each part of the river structure is to be established.

The present invention has a step of installing the measuring means for outputting the displacement information of the river structure in real time to the weak part of the river structure to build the system.

As shown in FIG. 3, the measuring means includes: an upper cover 10 having a first screw thread 11 at a lower portion thereof; and a first screw part coupled to the first screw thread 11 of the upper cover 10 at an upper side thereof. A nipple-shaped transmission panel 20 having a second thread 22 on the lower side and a connection panel 30 having a second screw part 32 on the inner circumferential surface thereof, the second screw part 22 engaging with the second thread 22; A body 40 having a screw thread 41 connected to the second screw portion 32 on the upper outer circumferential surface thereof, bent inwardly from the lower opening, and having a male screw portion 42 on the outer circumferential surface; An insertion panel 50 embedded in the body 40 and having a pair of insertion grooves 51 formed through the inner circumferential surface and the outer circumferential surface thereof in a vertical direction; A weight center portion 60 having a female screw portion 62 coupled to the male screw portion 42 of the body 40 and having a conical shape; And a communication unit 72, a control unit (not shown), and a power supply unit 73 connected to the displacement sensor 71 and the antenna 72a for detecting the displacement information, and the insertion groove 51 of the insertion panel 50. It comprises a; measuring sensor consisting of a main body 75 of the flat plate sliding to the.

The body 40, the center of gravity 60 and the connection panel 20 is preferably made of a material such as metal is formed so as not to be affected by external factors as possible, and furthermore, the center of gravity coupled to the lower portion of the body 30 60 is preferably made of a material that is heavier than the body and is formed in a conical shape so as to grasp the center of the measuring means when the underground is buried and more accurately detect the displacement change. The coupling method of the lower portion of the body 34 and the center of gravity 60 is sufficient if it is sealed to prevent the inside of the body from the penetration of moisture and the like. In addition, the upper cover 10 can be opened and closed, but closed, for failure, replacement, or upgrade of the measurement sensor 70 including the recycling of the measurement means or the power supply device 73, and the like. desirable.

The measuring means may be buried underground at a predetermined interval by arranging several measuring means in a line or in parallel according to the length, shape, and size of the river structure. In the preferred underground embedding embodiment of the measuring means according to the present invention, as shown in Figure 4, it is preferable to bury in a line at intervals of about 500M along the river structure, but concentrated at a narrower interval in the weak section set in the previous step It is more preferable to bury it. In addition, the measuring means is embedded at a predetermined depth to collect displacement information of the river structure, the measuring means of the river structure monitoring system according to the present invention is preferably buried below the average surface height of the river, the previous step It is more preferable to concentrate in the weak part set in different depth. As described above, since the collapse of the river structure starts from the bottom of the river structure and changes in displacement occur, the measurement means embedded at a predetermined depth of the river structure can collect more accurate displacement change information.

Subsequently, when the measuring means is installed in the partitioned river structure, displacement information of the river structure is collected. Will have a step of transmitting. For this step, the present invention is directed to problems such as design, construction, maintenance, etc. related to sedimentation, infiltration, slope stability, etc. of the groundwork and groundwork, which are directly and indirectly related to the displacement of river structures. In order to grasp the cause of the bank collapse and collect the information, a measurement sensor is used to detect the displacement of the river structure.

As described above, the measuring means has a built-in measuring sensor having a displacement sensor, the displacement sensor is preferably made of a sensor that can detect the inclination of the river structure. Patent Publication No. 10-2006-0074672 (published on July 03, 2006) is a capacitor unit for outputting a change value of the charge capacity according to the displacement change; It includes a displacement calculator that detects the charge capacity value between the electrode of the capacitor and the dielectric and calculates and outputs a displacement, and replaces a MEMS chip as a displacement sensor and is mounted on a mobile communication terminal. Displacement detection device that is mounted on the lower end of the device to detect the displacement of the PCB by measuring the amount of change in the charge capacity that changes according to the displacement change of the PCB, and is proposed as a compact as the displacement detection device of the invention It is preferable to use a displacement detection sensor embedded in the measuring means and capable of detecting the slope of the river structure such as displacement change.

In order to accurately collect information of the measurement means incorporating the displacement sensor 71, it is necessary to stably fix the measurement sensor 70. To this end, as shown in FIG. 3, the measuring means according to the present invention includes a separate inserting panel 50 to allow the measuring sensor 70 to be inserted and the inserting panel 50 to the body of the measuring means. 40). At this time, both end portions of the main body of the measurement sensor 70 is coupled to the insertion groove 51 of the insertion panel 50, the insertion panel 50 is bonded to the surface bent to the inner bottom of the body 40 By being fixed and embedded in such a manner as to be coupled, the displacement sensor 70 can accurately detect the tilt displacement of the river structure. In this case, when the outer diameter of the insertion panel is w1, and the inner diameter of the body is w2, it has a size relationship of w1 <w2, characterized in that there is a separation space between the insertion panel and the body. Due to this space, the measuring means can minimize the detection of incorrect displacement information due to external factors such as shock or vibration from the outside.

Furthermore, as a means for fixing the measurement sensor more firmly in order to prevent the collection of information of the displacement sensor 71 from external factors such as external shock or vibration, as shown in FIG. The measuring means according to the modification may further include a separate separation panel 80. The separation panel 80 embedded in the body 40 in combination with the measurement sensor 70 is formed to protrude in the vertical direction on the inner circumferential surface and slides into the insertion groove 51 of the insertion panel 50. Has In addition, the inner end of the insertion guide 81 is further provided with a fixing groove (81a) that can be slidingly coupled to both end portions of the main body 75 of the measurement sensor (70). In addition, the separation panel 80 further includes a fixing rail 82 protruding from the outer circumferential surface and formed in the vertical direction. The fixing rail 82 abuts on the inner circumferential surface of the body 40 to form a space with the spaced apart panel 80 to fix the insertion panel 50.

In other words, as illustrated in the upper left side view of FIG. 7, the size correlation between the body 40, the insertion panel 50, and the separation panel 80 will be described. Virtual grooves connecting the outermost side of the high-cut rail d1, the inner diameter of the separation panel 20 d2, and the fixing groove 81a provided in the pair of insertion guides 81 of the separation panel 80. When the width connecting the inside of d3 is d3, a size relationship of d3 <d2 <d1 is formed, so that the space between the separation panel 80 and the body 40 coupled to the measurement sensor 70 is provided. In addition, the measurement sensor 70 not only minimizes the disturbance of accurate displacement information collection due to external factors such as external vibration or shock, but also allows the measurement sensor to be dually fixed, thereby enabling more robust fixing to obtain more accurate information collection. can do.

Furthermore, as shown in the enlarged view represented by the lower left dashed line in FIG. 7, the spaced apart panel 80 may be easily inserted into the insertion panel 50, and the spaced apart panel 80 may not be discharged after insertion. Has an insertion member 82 protruding from the end is bent upward, the insertion panel 50 has an insertion tab 52 in contact with the insertion member 82 on the outer peripheral surface. The insertion member 82 is formed in a 'b' shape bent upwards, the insertion tab 52 is made of a concave-convex shape such as a screw thread when inserted there is no interference of the insertion member 82, but when discharged Since the distal end of the insertion member 82 is bent upward, it is prevented from being caught by the unevenness of the insertion tab 52, thereby ensuring a firm fixing of the separation panel 80, which is the measurement sensor 70. Since it is intended to secure the fixed, it can help to collect the accurate information of the displacement sensor (71).

In addition, since the displacement sensor 71 of the measuring means has to collect displacement information of the river structure for a long time, the power consumption is low and the accuracy of detecting the displacement change of the river structure is required. The precision of the displacement sensor can be selected differently according to the embedding position of the measuring means. When buried in the slope of the river structure, high accuracy is required as a sensitive part, and when buried in the lower portion of the river structure, the river scour occurs frequently and requires relatively lower precision than the bank slope. Can be selected according to the depth of burial and the shape and size of river structures.

In order to monitor the displacement of the river structure in real time, the present invention is installed in all or part of each river structure through the communication unit 72 of the measurement sensor 70 built in the measurement means, as shown in Figures 4 and 5 A plurality of measuring means to be formed to include an information collecting unit which is a local area network formed in the form of a mesh. In the measuring means according to the present invention, the communication unit 72 of the measuring means is capable of smoothly transmitting information even in the ground, without noise. The communication unit for forming the information collecting unit may include all of the various communication technologies of the prior art, in particular, using the Zigbee module proposed in Patent Publication No. 10-2008-0000290 (January 02, 2008 published date) desirable. The present invention uses a ZigBee communication to collect and manage the status information of various monitoring targets, such as a boiler provided in a common house without a separate network, each has a ZigBee communication module having identification information and transmitting and receiving data between each other It includes, and receives the status information output from the sensing means for detecting the status of each part of the device and outputs the status information received through the Zigbee communication module or received through the Zigbee communication module, the shortest distance to the left and right of the apartment house A plurality of monitoring objects grouped into monitoring objects adjacent to and adjacent to the shortest distance up and down; At least one local server for receiving, collecting and outputting state information transmitted for each monitoring group; It provides a monitoring system using a Zigbee configured to include; central server for providing the device status information provided from the local server to the administrator, and stores and processes it. By using the Zigbee module method, all of the river structures or parts of the river structures divided into zones form an information collection unit constituting a local area network.

Furthermore, the present invention, as described above, for the smooth formation of the above-described information collecting unit, the upper cover 10 and the transmission panel 20 is preferably made of a PVC material or the like without interference. As shown in Figure 3, the measuring means is provided with a transmission panel 20 made of a PVC material and made of a nipple shape. This is because when the insertion panel 50 coupled to the measurement sensor 70 is embedded in the connection panel 30 and the body 40, the displacement due to the connection panel 30 and the body 40 made of a metal material This is because the information may not be transmitted smoothly due to interference caused by the characteristics of the material. The connection panel 20 is inevitably formed on the outer surface of the body 40 due to the insertion panel 50 in which the body 40 is embedded. Ease of interference is impossible and can only be combined by screwing or the like. At this time, when screwing the materials with different hardness, since the small hardness of the connection panel 30 can be easily damaged by external impacts, etc. If the fixing of the connection panel 50 is relaxed later, as a measuring means, displacement sensor It may be difficult for 71 to collect accurate displacement information of the stream structure.

Accordingly, the present invention introduces a metal connecting panel 20 to the body 40 and the interference fit with the body 40, thereby ensuring a long and secure coupling between the measuring means components, and furthermore a transmission panel 20 with less interference The antenna 72a, which will be described later, is positioned inside the transmission panel 20 to enable smooth transmission of displacement information of the stream structure.

In order to achieve the object as described above, in order to forcibly fit the connection panel 30, a separate interference fitting member 90 is required, as shown in the partial perspective line divided by the right chain line of FIG. 90 has a bolt portion 91 to be coupled to the second screw portion 32 of the connection panel 30, made of the same metal material. At this time, the upper outer circumferential surface of the body 40 is formed flat and the connection panel 30 coupled with the interference fitting member 90 is placed in contact with the upper opening of the body 40, a strong striking means such as a hammer By pressing the second screw portion 32 of the connecting panel 30 to the outer peripheral surface of the body 40, it is possible to enable a firm fixed coupling between the components of the measuring means. Alternatively, the second screw part 32 of the connection panel 30 coupled to the interference fitting member 90 may be attached to the outer circumferential surface of the body by using the rotational clamping part 92 formed on the interference fitting member 90. By forcing screw tightening, it is possible to enable a firmer fixing than the general screw bolt, nut coupling method. When the fixing of the connection panel 30 through the interference fitting member 90 is completed, the screw coupling of the interference fitting member 90 and the connection panel 30 is released and the nipple shape of the transmission panel 20 is formed. The second screw thread 22 is coupled to the second screw portion 32 of the connecting panel 30, and the first screw thread 11 of the upper cover 10 and the first screw portion 21 of the transmitting panel 20 are connected to each other. By combining), the stream structure displacement real-time monitoring system according to the present invention facilitates the information transmission of the measurement sensor, and has a measuring means capable of collecting accurate displacement information due to the rigid fixed coupling, to form an information collecting unit for the purpose It becomes possible.

In order to prevent the penetration of moisture and the like into the measuring means, the present invention provides a sealing auxiliary means such as an O-ring or a flat ring made of a material such as rubber to each of the coupling portions to which the respective components are coupled. It may be further provided. Through the hermetically sealed auxiliary means, the measuring means prevents the infiltration of soil, insects, and the like, as well as preventing water from ingress due to the infiltration of rainwater or rivers, thereby preventing failures, and collecting and transmitting displacement information of safe and accurate river structures. Can be. When the displacement information of the stream structure is smoothly collected and transmitted from each measuring means through such a configuration, the information collecting unit wirelessly connects to the gateway to transmit the collected information to the control unit.

Subsequently, as shown in FIGS. 4 and 5, the control unit collects and receives displacement information collected and transmitted by the measuring unit forming the information collecting unit, and monitors the displacement risk in real time. The control unit in the step is characterized in that the information collected from all the river structures in Korea are integrated into one through each gateway. At this time, the control unit has a single web server, and integrated the information of each river structure delivered from all river structures in the country by administration, watershed, river, name, etc. to build a database to analyze the web server By storing the information on the stream structure in real time, establishing a comprehensive real-time monitoring and preventive management system, and moving away from the local or one-sided analysis system, so that the entire access to all the river structures in Korea is possible. can do. In addition to the real-time monitoring of the stream structure, the information constructed by the database provides information for maintenance and repair of the river structure in the future, and analyzes the database information and compares the stored displacement information to predict risks. By further including, the risk of displacement of the river structure is foreseen in advance, and the databased information is analyzed to enable various studies to prevent the collapse of the river structure when designing river structures such as new river structures.

Furthermore, as shown in Figure 6, the web server of the control unit is formed to be interoperable with the portable terminal. As an embodiment of the present invention, it is desirable to enable a river structure inquiry service that can easily and quickly find the river structure information in real time by using an application such as a smartphone. The application is also more preferably to enable the display of database information by searching by watershed, river, name.

Subsequently, the measuring means further includes a function of collecting and transmitting displacement information of the river structure, and transmitting and receiving an alarm signal when the risk of collapse of the river structure occurs by analyzing and comparing it with previous displacement information at the time of transmitting the information. The control unit not only prevents the collapse of the river structure through real-time monitoring of the river structure information, but also transmits an alarm signal from the measuring unit, and when the control unit receives the alarm signal, information of the measuring unit through the remote control device. By shortening the collection and transmission intervals to enable intensive river structure information monitoring, the effect of preventing river structure collapse can be further enhanced.

Furthermore, the measurement means of the real-time monitoring system for preventing the collapse of the river structure according to the present invention is not only buried underground in the river structure, but also to make a variety of installations according to the shape and characteristics of the river structure by making a deformable attachment type. In addition, the measuring means not only has a built-in displacement sensor, but also includes a submersion sensor, a pore pressure gauge, a leak gauge, a strain gauge, and the like to collect various information for preventing the collapse of the river structure, thereby real-time river structure displacement. Maximize the use of the monitoring system.
