Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
[Overall system configuration]
FIG. 1 is an overall configuration diagram of a nondestructive exploration system 1 according to an embodiment of the present invention.
As shown in FIG. 1, the nondestructive exploration system 1 of the present embodiment includes a wheeled probe 2 used for nondestructive exploration of a structure, and superimposes the investigation results of the probe 2 on a cross-sectional view of a tunnel T. and a display device 3 for displaying.

The probe 2 of this embodiment is a non-destructive investigation device that detects the position and size of an object or cavity existing in a structure using an electromagnetic wave radar. For example, "STRUCTURE SCAN" manufactured by KEYTEC Co., Ltd. can be used as this exploration device.
The probe 2 using an electromagnetic wave radar emits an electromagnetic wave W of the order of 1000 MHz toward the structure, for example, and receives a diamagnetic wave from the boundary surface with the cavity or the boundary surface where the material changes, thereby detecting the structure. Detect the position and size of an object or cavity within.

The probe 2 includes a device main body 20 and a communication device 21 connected to the device main body 20 . The device main body 20 has four wheels 22 and is movable along the moving direction X. As shown in FIG.
The apparatus main body 20 has a transmitting/receiving section (not shown) for electromagnetic waves W on the bottom side, and a grip section 23 that can be held by the operator 4 at the rear end. An operation part 24 such as a switch or a button is provided at the tip of the grip part 23 . The apparatus main body 20 has a liquid crystal display 25 on the upper surface side. The liquid crystal display 25 displays an initial setting screen, a graph showing search results, and the like.

Non-destructive exploration by the probe 2 is carried out, for example, by a worker 4 who brings a work trolley 5 into the tunnel T and rides on the work trolley 5 . As the work cart 5, for example, "Mobile Work Station" manufactured by TechnoPro Co., Ltd. may be used.
A worker 4 riding on a work vehicle 5 moves the probe 2 in a certain direction by bringing the wheels 22 into contact with the inner surface of the lining concrete C, and moves the probe 2 from the inner surface of the lining concrete C to the outside of the tunnel T in the radial direction. Explore objects and boundary surfaces located on the (ground side).

The search data output by the probe 2 to the liquid crystal display 25 includes the movement distance when the probe 2 is moved in the movement direction X, and waveform data Di ( i=1, 2...).
Here, it is assumed that the lining concrete C is plain, and the outer surface of the lining concrete C is the target of the non-destructive inspection. This is because if the outer surface of the lining concrete C can be estimated, it can be determined whether the thickness of the lining concrete C is as designed.

Therefore, the vertex of each waveform data Di represents the position in the depth direction Y of the outer surface of the lining concrete C at each position in the movement direction X. As shown in FIG.
However, if each waveform data Di includes vertices representing positions in the depth direction Y of the ground at each position in the movement direction X, the target of the nondestructive exploration may be the inner surface of the ground. can.

The communication device 21 is a wireless communication device conforming to a predetermined communication standard such as a wireless LAN. The communication device 21 is communicably connected to the device body 20 via a predetermined communication cable.
The communication device 21 has a predetermined information input section (not shown). The input information to the communication device 21 includes type information of the moving direction X of the probe 2 and measurement point information of the position at which the non-destructive inspection is started (the position where the probe 2 is first set).

FIG. 2 is an explanatory diagram showing an example of the type information of the moving direction X of the probe 2 and the measurement point information of the exploration start position P. As shown in FIG.
Here, it is assumed that the exploration start position P is the position on the center line L on the inner surface of the lining concrete C. As shown in FIG. Also, the survey point number of the exploration start position P is set to, for example, No. Assume that it is 100+10.00 (m).

As shown in FIG. 2, the type information of the moving direction X specifies one of the direction 1R, the direction 1L, and the direction 2. As shown in FIG.
A direction 1R represents a clockwise direction in the circumferential direction (transverse direction) of the tunnel T. FIG. A direction 1L represents a counterclockwise direction in the circumferential direction (transverse direction) of the tunnel T. FIG. Direction 2 represents the traveling direction of the tunnel T (longitudinal direction).

When starting the nondestructive exploration of the tunnel T, the worker 4 inputs the type information of the movement direction X and the measurement point information of the exploration start position P to the communication device 21 .
For example, when moving the probe 2 clockwise from the exploration start position P, the operator 4 inputs the type information=direction 1R and the position P=100+10.00 to the communication device 21 .

When moving the probe 2 counterclockwise from the exploration start position P, the worker 4 inputs the type information=direction 1L and the position P=100+10.00 to the communication device 21 .
When moving the probe 2 from the exploration start position P in the traveling direction (longitudinal direction) of the tunnel T, the worker 4 inputs the type information = direction 2 and the position P = 100 + 10.00 to the communication device 21. .

When the communication device 21 receives the exploration data (the movement distance of the exploration device 2 and the waveform data Di of each position within the movement distance) from the device body 20 , the communication device 21 transmits the received exploration data to the display device 3 .
Along with the exploration data, the communication device 21 displays the type information of the movement direction X (for example, direction 1R) input by the worker 4 at the start of the nondestructive exploration and the survey point information of the exploration start position P (for example, 100+10.00). Send to device 3.

If the probe 2 can receive the type information of the movement direction X and the survey point information of the search start position P, such information may be input to the operation unit 24 of the probe 2 .
In this case, the device body 20 transmits the input type information and survey point information to the communication device 21 together with the survey data. The communication device 21 transfers the type information and survey point information received from the device body 20 to the display device 3 together with the survey data.

[Display mode decision processing]
FIG. 3 is a flowchart illustrating an example of display mode determination processing. FIG. 7 is an explanatory diagram showing an example of the initial setting screen G0 and input screens G1 to G3 displayed on the display unit 33. As shown in FIG.
As shown in FIG. 3, the control section 34 of the display device 3 causes the display section 33 to display the "initial setting screen G0" (see FIG. 7) of the display mode (step ST31).

Next, the control unit 34 determines whether or not the user has input a display mode selection (step ST32). Specifically, the control unit 34 determines whether or not any of the selection icons A1 to A3 included in the initial setting screen G0 has been operated by the user.
When there is the above selection input, the control section 34 determines which one of the selection icons A1 to A3 has been selected (step ST33).

When the selection input by the user is "A1", the control unit 34 causes the display unit 33 to display the "transverse display input screen G1" (see FIG. 7), and performs a cross-sectional display process (step ST34: FIG. 4). transition to
When the selection input by the user is "A2", the control unit 34 causes the display unit 33 to display the "longitudinal display input screen G2" (see FIG. 7), and performs longitudinal display processing (step ST35: FIG. 5). transition to

When the selection input by the user is "A3", the control unit 34 causes the display unit 33 to display the "single point display input screen G3" (see FIG. 7), and performs single point display processing (step ST36: FIG. 6).

[Transverse display processing]
FIG. 4 is a flow chart showing an example of the horizontal display process.
As shown in FIG. 4, the control unit 34 of the display device 3 determines whether or not the user has input the measurement point position (step ST41). Specifically, the control unit 34 determines whether or not the value of the measurement point position of the tunnel T has been input in the input box for "measurement point" included in the input screen G1 for cross-sectional display.

When the above information is input, the control section 34 acquires the value of the crossing parameter of the tunnel T corresponding to the input measurement point position (step ST42).
The traversing parameters include the SL (spring line) height and inner diameters R1, R2 of the tunnel T. The user inputs the value of the traverse parameter to the input screen G1. However, if the storage unit 35 has CAD data of the tunnel T, the control unit 34 may read the values of the traversing parameters corresponding to the input measurement point positions from the CAD data.

Next, the control section 34 generates a traversing line of the inner surface of the lining concrete C corresponding to the input measurement point position based on the acquired traversing parameter value, and outputs it to the display section 33 (step ST43). .
As a result, the display unit 33 displays the cross-sectional shape of the inner surface of the tunnel at the input measurement point position on the cross-sectional display result display screen K1 (see FIG. 8).

Next, the control unit 34 determines whether or not there is survey data in the transverse direction corresponding to the input survey point position (step ST44).
Specifically, the control unit 34 determines that the survey point information of the survey start position matches the value of the survey point position input on the screen G1 from the survey data recorded in the database 37, and the moving direction X The presence or absence of search data whose type information is direction 1R and direction 1L is determined.

If the determination result in step ST44 is affirmative, the control unit 34 uses the exploration data in the direction 1R and the direction 1L read from the database 37 to estimate the transverse direction shape of the outer surface of the lining concrete C and the inner surface of the natural ground. is calculated, and the calculated estimated shape is output to the display unit 33 (step ST45).
As a result, the display unit 33 displays the estimated shape in the transverse direction of the outer surface of the lining concrete C and the natural ground corresponding to the input measurement point positions on the result display screen K1 (see FIG. 8) of the transverse display.

The calculation of the estimated shape is performed based on the depth of the vertex position of each waveform data Di included in the exploration data. Specifically, the control unit 34 generates an arc axis along the circumferential shape of the inner surface of the lining concrete C and a coordinate system whose depth direction is radially outward of the arc axis.
Then, the control unit 43 plots the depth of the vertex position of the waveform data Di at each position on the arc axis when the moving direction Y of the probe 2 is superimposed on the arc axis, and plots each plotted depth on the coordinate system. An estimated shape is calculated by connecting the points with straight lines or complementary curves.

When the determination result of step ST44 is negative, the control section 34 outputs to the display section 33 information to the effect that there is no exploration data for the input measurement position (step ST46).
In this case, for example, the display unit 33 displays a dialog box containing an alert message such as "no exploration data". As a result, the user perceives that there is no search data in the transverse direction at the input measurement point position.

[Longitudinal display processing]
FIG. 5 is a flowchart illustrating an example of longitudinal display processing.
As shown in FIG. 5, the control unit 34 of the display device 3 determines whether or not the user has input an operation for measuring point sections (step ST51). Specifically, the control unit 34 determines whether or not the value of the measurement point section of the tunnel T has been input to the input box for "measurement point" included in the input screen G2 for vertical section display.

When the above information is input, the control section 34 generates a longitudinal section line of the inner surface of the lining concrete C in the input survey point section, and outputs it to the display section 33 (step ST52).
As a result, the display unit 33 displays the longitudinal shape of the inner surface of the tunnel in the input survey point section on the result display screen K2 (see FIG. 9) for longitudinal display.

Next, the control unit 34 determines whether or not there is survey data in the longitudinal direction corresponding to the input survey point section (step ST53).
Specifically, the control unit 34 determines that the survey point information of the survey start position P from the survey data recorded in the database 37 matches the value of the start position of the cartwheel section input to the screen G2, and , the presence or absence of search data in which the type information of the movement direction X is direction 2 is determined.

If the determination result in step ST53 is affirmative, the control unit 34 calculates the estimated shape in the longitudinal direction of the outer surface of the lining concrete C and the inner surface of the natural ground from the exploration data of the direction 2 read from the database 37. , the calculated estimated shape is output to the display unit 33 (step ST54).
As a result, the display unit 33 displays the outer surface of the lining concrete C corresponding to the input survey point section and the estimated shape of the ground in the longitudinal direction on the longitudinal result display screen K2 (see FIG. 9).

The calculation of the estimated shape is performed based on the depth of the vertex position of each waveform data Di included in the exploration data. Specifically, the control unit 34 generates a coordinate system in which the horizontal axis is the longitudinal direction of the inner surface of the lining concrete C and the upper side of the vertical axis is the depth direction.
Then, the control unit 34 plots the depth of the vertex position of the waveform data Di at each position on the horizontal axis when the moving direction Y of the probe 2 is superimposed on the horizontal axis, and plots each plotted depth on the coordinate system. An estimated shape is calculated by connecting the points with straight lines or complementary curves.

When the determination result of step ST53 is negative, the control section 34 outputs to the display section 33 a reminder that there is no survey data for the input measurement section (step ST55).
In this case, for example, the display unit 33 displays a dialog box containing an alert message such as "no search data". As a result, the user perceives that there is no search data in the longitudinal direction in the input survey point section.

[Single point display processing]
FIG. 6 is a flowchart illustrating an example of single-point display processing.
As shown in FIG. 6, the control section 34 of the display device 3 determines whether or not the user has input the measurement point position (step ST61). Specifically, the control unit 34 determines whether or not the value of the measurement point position of the tunnel T has been input to the input box for "measurement point" included in the single-point display input screen G3.

When the above information is input, the control unit 34 generates a cross-sectional line of the inner surface of the lining concrete C at the input measurement point position and outputs it to the display unit 33 (step ST62).
As a result, the display unit 33 displays the height position of the inner surface of the tunnel at the input measurement point position on the single-point display result display screen K3 (see FIG. 10).

Next, the control unit 34 determines whether or not there is survey data in the transverse or longitudinal direction corresponding to the input survey point position (step ST63).
Specifically, the control unit 34 determines whether or not there is survey data, which is a survey range including the measuring point position input on the screen G3, from the survey data for the direction 2 recorded in the database 37 .

If the determination result in step ST63 is affirmative, the control unit 34 estimates the outer surface of the lining concrete C and the inner surface of the natural ground at the measurement point position input on the screen G3 from the survey data read from the database 37. The height is calculated, and the calculated estimated height is output to the display section 33 (step ST64).
As a result, the display unit 33 displays the estimated heights of the outer surface of the lining concrete C and the inner surface of the natural ground corresponding to the input survey point section on the single-point display result display screen K3 (see FIG. 10). .

The calculation of the estimated height is performed based on the depth of the vertex position of the waveform data Di of the measurement position input to the screen G3 included in the survey data.
Specifically, the control unit 34 plots the vertex position of the waveform data Di above by the depth of the vertex position with the inner surface position of the lining concrete C as the origin, and plots a predetermined point including the plotted point. Let the line segment of length be the estimated height.

If the determination result of step ST63 is negative, the control section 34 outputs to the display section 33 a reminder that there is no investigation data for the input measurement position (step ST65).
In this case, for example, the display unit 33 displays a dialog box containing an alert message such as "no search data". As a result, the user perceives that there is no search data in the longitudinal direction in the input survey point section.
