The internal sensor unit 110 is installed in at least one or more positions of the dangerous and fragile structure, and detects the pressure of the pore, the pressure of the earth, the pressure of the water, the stress, the tension applied to the dangerous and fragile structure, A dynamic load generated in the risk-vulnerable structure, a temperature of the vulnerable structure, an internal groundwater level of the vulnerable structure and a water level of the adjacent water level, a permittivity and a water content of the vulnerable structure, and a slope of the vulnerable structure And at least one of them is measured.

4, the internal sensor unit 110 includes a stress / pressure measurement sensor 111, a displacement measurement sensor 112, a dynamic load measurement sensor 113, a temperature measurement sensor 114, A measurement sensor 115, a TDR measurement sensor 116, and an inclination measurement sensor 117.

The stress / pressure measuring sensor 111 measures the pore water pressure, the earth pressure, the hydrostatic pressure, the stress, and the tensile force applied to the vulnerable structure.

The displacement measurement sensor 112 measures the surface displacement, ground displacement, and settlement occurring in the vulnerable structure.

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

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

The level measuring sensor 115 measures the level of the groundwater in the vulnerable structure and the level of the adjacent water surface.

The TDR measurement sensor 116 measures the permittivity and water content of the vulnerable structure.

The inclination measuring sensor 117 measures the inclination of the vulnerable structure.

The external sensor unit 120 includes a measurement sensor 121, a settlement sensor 122, a vulnerable 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 at the time of triangulation, and a displacement in the upstream and downstream directions of the vulnerable structure. , And a transit.

Next, the electrical resistivity measurement module 130 is located in the vulnerable structure, and performs a function of measuring the electrical resistivity of the vulnerable 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.

Electrode array methods used for electrical resistivity survey are: Pole-Pole, Pole-Dipole, Dipole-Dipole, Schlumberger, Wenner, Modified Pole- Pole and Modified Dipole-Dipole arrays.

7A is a graph showing an electrical resistivity distribution of an inverse analysis of the electrical resistivity survey using the dipole array of 5 m in the lateral direction of the vulnerable structure in the lateral direction, FIG. 7C is a result of inverse analysis of electrical resistivity survey using a modified dipole array of 10 m. FIG.

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 control unit 140 controls the operation of the electrical resistivity measurement module 130. When receiving the integrated trigger signal, the control unit 140 transmits measured values before and after the event of the electrical resistivity measurement module 130 to the manager's mobile phone, Or a monitoring server. In addition, the controller 140 controls the operation of the internal sensor unit 110. When receiving the integrated trigger signal from the integrated trigger module 1100, the control unit 140 controls the internal sensor unit 110, the external sensor unit 120, and the electrical resistivity measurement module 130, To at least one of the administrator terminal or the monitoring server (300).

 The resistivity measuring transceiver console 150 is interlocked with the monitoring server 300 through a wireless interface and is connected to the at least one internal sensor unit 110 and the external sensor units 120 and the electrical resistivity measurement module 130. [ And receives a control signal provided by the risky vulnerable structure management server 400. The risk-vulnerable structure management server 400 receives the control signal from the vulnerable structure management server 400,

When the integrated trigger signal is generated from the integrated trigger module 1100, the vulnerable structure measurement module communication unit 160 transmits the integrated trigger signal to the drones 600, the manager's mobile phone, So that the communication function can be performed.

Next, the earthquake measuring module 200 is provided in a peripheral area and inside of the dangerous and fragile structure, measures earthquake information according to an earthquake occurrence in real time, and provides the measured earthquake information to the monitoring server 300 Function.

2A to 2C, the seismic measuring module 200 includes at least one or more of an earthquake measuring instrument 210, an MCU 220, an earthquake measuring transmission / reception console 230, and an earthquake measuring module communication unit 240 ).

The at least one earthquake measuring instrument 210 may be a unit for detecting shaking and shocking signals generated in the ground in real time and then providing a sensed signal to the MCU 220. The earthquake measuring instrument 210 ) May be a borehole located in the ground of the surrounding area of the above-mentioned vulnerable structure or an indicator type positioned below or above the above-mentioned vulnerable structure.

Next, the MCU 220 performs a function of calculating the average value after summing the measurement information measured by the at least one earthquake measuring instrument 210.

The seismic measurement transmission / reception console 230 provides the monitoring server 300 with the calculation information calculated by the MCU 220 using a wireless interface.

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.

If the integrated triggering module 1100 generates an event in which a measurement signal exceeding a reference threshold value is measured in any one of the vulnerable structure measurement module 100 or the seismic measurement module 200, And transmits the integrated trigger signal to the sensors constituting the structure measuring module 100, the earthquake measuring instruments constituting the earthquake measuring module 200, and the drones 600, so that the drones 600 are taken off, And transmits the measurement values before and after the occurrence of the event in real time to the vulnerable structure measurement module 100 and the seismic measurement modules 200.

In this case, the abnormal value (or threshold value) of the electrical resistivity measurement value can be set to a case where a 10% reduction in the steady state occurs. In the case of the seismic measurement value, Can be set to a value corresponding to the degree of progress.

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 determines the occurrence of an abnormality in the case where the difference is large in comparison with the previously captured thermographic image by recognizing the change in the temperature distribution in the transmitted thermographic image and recognizing the leak or the like, Real-time monitoring of the structure can be performed. Also, in case of a high-resolution photographed image, it is possible to judge whether or not the risky structure is abnormal in real time in comparison with a previously photographed image.

Next, the monitoring server 300 determines whether the electrical resistivity measurement values received from the electrical resistivity measurement module 130 or the earthquake measuring instruments by the integrated trigger signal of the integrated trigger module 1100 or the event occurrence of the seismic measurement values And outputting status abnormality information and an alarm when a difference outside the range of the reference threshold value occurs.

The monitoring server 300 stores and manages information measured by the vulnerable structure measuring module 100 and the earthquake measuring module 200 in real time and measures the earthquake intensity The method includes the steps of calculating a distribution of the electrical resistivity of the variable vulnerable structure, comparing the electrical resistivity generation amount of the vulnerable structure generated during a predetermined period of time with the threshold value of electrical resistance per section set therein, Of the periodic electrical resistivity exceeds the electrical resistivity threshold value for each of the sections, provides the status abnormality information of the vulnerable structure according to the section specific electrical resistivity threshold value.

More specifically, the earthquake recorder 310 may perform a function of recording and storing earthquake information provided by the earthquake measuring instrument in real time, or recording and storing earthquake information exceeding a reference threshold value.

The earthquake event trigger generator 320 extracts a maximum ground acceleration (PGA) value from the seismic information recorded in the earthquake recorder, compares the maximum ground acceleration (PGA) value with a reference threshold value provided therein, The electrical resistivity distribution diagram performs a function of generating a driving signal of the calculation unit.

The electrical resistivity distribution calculating unit 330 may include a plurality of electrical resistivity intervals arbitrarily set therein and apply the electrical resistivity values provided by the electrical resistivity measurement module to the plurality of electrical resistivity intervals to calculate electrical resistivity And performs a function of calculating a resistivity distribution diagram.
