The stress / pressure measuring sensor 111 measures the pore water pressure, earth pressure, hydrostatic pressure, stress, and tension applied to the hydraulic structure.

The displacement measuring sensor 112 measures the surface displacement, ground displacement, and settlement occurring in the hydraulic structure.

The dynamic load measuring sensor 113 measures a dynamic load generated in the hydraulic structure.

The temperature measuring sensor 114 measures the temperature of the hydraulic structure.

The level sensor 115 measures a level of groundwater in the hydraulic structure and the level of the adjacent water surface.

The external sensor unit 120 includes a measurement sensor 121, a settlement sensor 122, a hydraulic structure axial direction sensor 123, and an upstream / downstream deformation sensor 124.

The measurement sensor 121 is a sensor for measuring at least one of a settlement of a surface of a hydraulic structure, a side angle at the time of triangulation, a distance during triangulation, and a displacement in the upstream and downstream directions of a hydraulic structure.

Next, the electrical resistivity measurement module 130 is located within the hydraulic structure and performs a function of measuring the electrical resistivity in the hydraulic structure in real time.

5, the electrical resistivity measurement module 130 includes an electrical resistivity electrode array 131, a switching box 132, and a switching controller 133. [

The electrical resistivity electrode array 131 may include a plurality of electrodes configured in a channel shape, and the plurality of electrodes may include at least one current electrode and at least one potential electrode.

In general, the electrical resistivity probe supplies electric power to two current electrodes (C1, C2) through an ammeter connected to a power source, and then a voltmeter connected to two potential electrodes (P1, P2) The resistance value is read by dividing the potential difference by the current flowing through the potential difference (see FIG. 6A).

That is, if a constant current is flowed through the current electrodes C1 and C2 to a uniform underground medium for electrical resistivity survey, the current flows from C1 to C2 through a current path. At this time, an equipotential line having a potential of the same value perpendicular to the current path is formed. The equipotential line is connected to the ground, and the potentiometer installed on the ground measures the entire position between the potential electrodes P1 and P2.

Using the position of the current electrode and the potential electrode, the amount of current flowing and the measured potential difference, the accurate resistivity value of the homogeneous underground medium can be known.

However, if anomalous body exists underground, the electric current flowing for electrical resistivity survey flows more toward the material with low electrical resistivity and eventually deforms the equipotential line perpendicular to the current path and affects the potential difference measured on the surface. From this, the potential difference measured from the surface of the earth is used to obtain information on the electrical anomaly of the underground medium, and an apparent resistivity can be obtained (see FIGS. 6B and 6C).

As described above, the electrical resistivity survey is a method of determining the apparent resistivity by measuring a potential difference after flowing a constant current in the ground as described above, and interpreting the geological structure of the underground, the fracture zone, and the groundwater.

Therefore, the driving principle of the electrical resistivity measurement module 130 according to the present invention is the same as that of the electrical resistivity survey described above, and thus a detailed description thereof will be omitted.

Meanwhile, the switching box 132 selectively switches among a plurality of electrodes, and provides the measured electrical resistivity value to the controller 140, selected from the plurality of electrode arrays.

The controller 140 controls the operation of the at least one internal sensor unit 110 and the electrical resistivity measurement module.

When the integrated trigger signal is generated from the integrated trigger module 1100, the seismic measurement module communication unit 240 communicates directly with the manager's mobile phone, the administrator terminal, or the monitoring server 300 To provide communication functionality.

Here, the earthquake measuring instrument 210 is equipped with a vibration sensor of three components, such as a rectangular coordinate. The three components are a longitudinal component, a transverse (axis) A transverse component, and a vertical component.

At this time, the three components are designed to be aligned in the north-south direction, the east-west direction, and the vertical direction with respect to gravity. In addition, the three vibration sensors are traditionally generally circular in shape on the plan view, and may be formed in a shape close to a quadrangle or in various deformed shapes.

For reference, seismic measurements are useful as fundamental resources for earthquake-resistant design by providing data for earthquake alert and response as well as data collection and database acquisition. Therefore, reliability of the application fields can be ensured only if reliable installation operation is premised on.

The earthquake measuring instrument of the present invention determines whether external vibration is generated based on the speed measurement or the acceleration measurement principle.

In addition, earthquake instruments usually have verticality through base work and level adjustment at the points of contact with the natural atmosphere (air), such as the surface of the earth, And install it considering the azimuth.

Exceptionally expensive borehole-based seismic measurements do not have free-field contact with the atmosphere, and their installation or operation may be performed by seismology or earthquake engineering experts Are generally involved in the planning, installation, and operation of the system.

On the other hand, instrument-based seismic measurements installed in free spaces are relatively inexpensive and universal. For this reason, the number of installed installations has been increasing rapidly in recent years, and there have been frequent instances where seismic or seismic engineering experts have been excluded and simple installations are made by non-experts.

When an event occurs in which the measurement signal exceeding the reference threshold value is measured in any one of the mathematical measurement module 100 or the seismic measurement module 200, the integration triggering module 1100 performs the measurement of the hydraulic structure And transmits the integrated trigger signal to the sensors constituting the module 100 and the earthquake measuring instruments constituting the earthquake measuring module 200 so that the hydraulic structure measuring module 100 and the earthquake measuring modules 200 can detect an event And transmits the measured values before and after the generation in real time.

The drone 600 includes a camera 610 such as a high resolution camera or a thermal camera and a precision GPS unit. When the integrated trigger signal of the integrated trigger module 1100 is received, the drone 600 takes off and moves to an event generation point, An infrared image capturing or high resolution image capturing is performed on the event occurrence point, and the captured image is transmitted to at least one of a manager's mobile phone, an administrator terminal, or a monitoring server. The manager or the monitoring server 300 recognizes a change in the temperature distribution in the transmitted thermographic image to recognize a leak or the like or compares the previously captured thermographic image with a previously captured thermographic image, So that it can perform real-time monitoring. Also, in case of a high-resolution photographed image, it is possible to judge whether or not the hydraulic structure is abnormal in real time compared with the previously photographed image.

Next, the monitoring server 300 stores and manages the information measured by the mathematical measurement module 100 and the seismic measurement module 200 in real time, and according to the seismic intensity, The electrical resistivity generation amount of the hydraulic structure generated during a predetermined period of time is compared with the electrical resistivity threshold value set in the interior of the hydraulic structure, And provides the abnormal state information of the hydraulic structure according to the section specific electrical resistivity threshold value when the specific electrical resistivity threshold is exceeded.

The comparator 350 compares and determines a threshold value of the reference electrical resistivity distribution diagram provided by the mathematical structure change determining unit and the electrical resistivity distribution diagram provided by the electrical resistivity distribution diagram calculating unit, When the resistivity distribution diagram exceeds the threshold value, an excess signal according to the excess range is provided to the alarm unit and the expected damage information providing unit 370.

The alarm unit 360 provides different types of alarm signals to the hydraulic structure management server according to the magnitude of the excess signal.

 The predicted damage information providing unit 370 estimates damage information (for example, flooding, loss, breakage, collapse, flooding, infiltration, infiltration, flooding, And includes at least one of scour, crack, exposed steel, bending, separation, deformation, and piping).

At this time, the expected damage information providing unit may be different according to the type, size and geographical position of the hydraulic structure, and may also be different depending on the life cycle of the hydraulic structure, the design year, and the number of times of maintenance / reinforcement. Therefore, even if the same type of hydraulic structure, the expected damage information may be different.

Therefore, the monitoring server 300 provided in the present invention monitors changes in electrical resistivity in a hydraulic structure at the time of occurrence of an earthquake, so that changes in the behavior of the hydraulic structure due to an earthquake can be monitored in real time through electrical resistivity. After the earthquake, damage to hydraulic structures can be provided.

Specifically, the monitoring server 300 compares the measured values received from the sensors and the earthquake measuring instruments by the integrated trigger signal of the integrated trigger module 1100 before and after the event occurrence time and then exceeds the reference threshold value And outputs the corresponding state information and alarm.

Next, after receiving the alarm signal, the mathematical structure management server 400 performs a function of providing a disaster warning message to the maintenance manager of the mathematical structure and the management server of the SME.

When the estimated damage information predicted by the monitoring server 300 exceeds the reference expected damage information set according to the repair structure, the repair structure management server 400 updates the maintenance structure of the repair structure, the repair structure, Provides a disaster warning message to a management server of a government office that performs prevention of damage caused by natural disasters such as a portable terminal of a local resident in the installed area, a fire emergency management center, a local police station, and a disaster evacuation headquarters.
