Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an outline of the configuration of the as-built measurement system 1 according to an embodiment of the present invention. The as-built measurement system 1 according to the present invention is for managing the as-built of the superstructure (bridge erection work, slab work, etc.) constructed in bridge construction, and obtaining each value such as the span length, total length, camber, sag, reference height, and width of the bridge. In the as-built measurement system 1 according to the present invention, the total station 30 and the level measuring instrument 40 measure and acquire the coordinate data of the grid points in the superstructure set at the design stage of the bridge, and use them for calculating the above-mentioned respective values based on the coordinate data.

[0018] Note that the coordinate data originally measured by the total station 30 is the position coordinates of the target prism 20 erected vertically at the grid points in the superstructure. However, in this specification, it is defined as the data related to the position coordinates of the grid points in the superstructure from which the height of the pole 25 to which the target prism 20 is attached is subtracted. Also, the height data measured by the level measuring instrument 40 is defined as the data related to the height at the position of the grid points in the superstructure. In summary, the measurement data by the total station 30 is the coordinate data (X, Y, Z) of the grid points in the superstructure, and the measurement data by the level measuring instrument 40 is the height data (Z) of the grid points in the superstructure.

[0019] The as-built measurement system 1 according to the present invention is assumed to perform one-person surveying of as-built measurement at the upper structure construction site of a bridge using a total station 30 and a level gauge 40, and to automatically create and output as-built forms. In addition, an information processing device such as a tablet terminal device 12 is used in combination with the total station 30 and the level gauge 40 so that the difference between the design value (also referred to as "design data") and the measured value (also referred to as "measured data") can be confirmed on-site, and the measurement results of the entire digits (span length, total length, camber, sag, reference height, width of the bridge) can also be confirmed. Further, for example, when surveying using the total station 30, a remote controller 50 is provided to realize the distance measurement operation of the total station 30 by operating a button switch in order to perform the distance measurement operation while holding the horizontal of the target prism 20.

[0020] In the as-built measurement system 1 according to the present invention, it is assumed that the total station 30 and the level gauge 40 are those capable of transmitting and receiving data with an information processing device such as a tablet terminal device 12 and a personal computer 13.

[0021] In the as-built measurement system 1 according to the present invention, in the tablet terminal device 12 carried by a worker who performs one-person surveying, the measurement results can be displayed, and the as-built form can be created and output. However, the data held by the tablet terminal device 12 can be transmitted to other devices (information processing devices such as the tablet terminal device 12 and the personal computer 13 shown on the right end of FIG. 1), and the measurement results can be displayed and the as-built form can be created and output on other devices.

[0022] For this purpose, all the tablet terminal devices 12 and personal computers 13 in FIG. 1 can be connected via the communication line 15 so as to enable data communication, and the data acquired by the tablet terminal device 12 carried by the worker can be shared by the cloud server 18. Note that, including the tablet terminal device 12, a person handling an information processing device that executes the formed shape measurement system 1 according to the present invention may be referred to as a "user" including the worker.

[0023] Next, the measurement mode by the formed shape measurement system 1 configured as described above will be described. FIG. 2 is a diagram showing a state of a bridge construction site where measurement is being performed by the total station 30 in the formed shape measurement system 1 according to an embodiment of the present invention.

[0024] A target prism 20 is attached to one end side of the pole 25. The target prism 20 is an object that the total station 30 automatically tracks and the total station 30 measures its position coordinates. Also, it is assumed that the worker holds the pole 25 so that the other end side of the pole 25 is arranged on the grid point in the upper work 5.

[0025] The tablet terminal device 12 is attached to the pole 25 by an attachment member 26, and the worker can operate the remote controller 50 while referring to the display device of the tablet terminal device 12. When the total station 30 performs measurement, accurate measurement becomes possible when the pole 25 is vertical (in other words, the target prism 20 is horizontal) when the pole 25 is placed on the grid point. The worker adjusts while holding the pole 25 so as to keep the target prism 20 horizontal, and by operating the remote controller 50 at an appropriate moment, the coordinate data of the grid point is taken into the tablet terminal device 12. Each process for this will be described later.

[0026] In the as-built measurement system 1 according to the present invention, in addition to the target prism 20 with respect to the pole 25, the fact that the tablet-type terminal device 12 is attached has greatly contributed to the operator maintaining the level of the target prism 20.

[0027] Next, the measurement mode by the level gauge 40 of the as-built measurement system 1 will be described. FIG. 3 is a diagram showing a state of a bridge construction site where measurement by the level gauge 40 is being performed in the as-built measurement system 1 according to the embodiment of the present invention. At each grid point in the upper structure 5, as shown in the figure, grid point names such as C4-G2 are respectively attached. The operator shown in FIG. 3 holds the barcode staff 45 horizontally above the position of C4-G2 and operates the tablet-type terminal device 12 and the remote controller 50 to capture the height data of the grid point at the grid point C4-G2 into the tablet-type terminal device 12.

[0028] Here, although the coordinate data (X, Y, Z) of the grid points in the upper structure can also be obtained by the total station 30, since the height data (Z) obtained by the level gauge 40 may be considered to be more accurate in some cases, in the as-built measurement system 1 according to the present invention, when the latter data can be obtained, the Z value of the former coordinate data (X, Y, Z) is corrected by overwriting it with the latter data.

[0029] Next, the processing and operation of the as-built measurement system 1 according to the present invention will be described while referring to the display on the display device of the tablet-type terminal device 12 carried by the operator. FIG. 4 is a diagram showing an example of a user interface screen on the display device of the tablet-type terminal device (information processing device) 12.

[0030] The display device used in the tablet terminal device 12 usually adopts a touch panel display, and the operator can touch the user interface screen with a finger to perform an input operation. Each input operation generally known as "tap", "double tap", "long tap", "flick", "swipe", "pinch" is also adopted in the system according to the present invention.

[0031] For the user interface screen shown in FIG. 4, for example, when the operator taps the displayed button, the command marked on the button is executed. In the as-built measurement system 1 according to the present invention, when the button UI1 is tapped, the design setting process is executed in the tablet terminal device 12.

[0032] FIG. 5 is a diagram showing a flowchart of the design setting process by the tablet terminal device 12. When the design setting process is started in step S1000, the process then proceeds to step S1001.

[0033] In this step S1001, the user is requested to input information regarding the design of the upper structure to be designed. Correspondingly, the user inputs design data (design values of the coordinate data (X, Y, Z) of the measurement grid points) corresponding to the measurement grid point names in the upper structure.

[0034] FIG. 6 is an example of a plan view showing the grid points of the upper structure. The grid points are defined as the intersections of the line Gn along the traveling direction of the road, the line Sn, the line Cn, and the line Pn (where n is all natural numbers) along the direction perpendicular to the traveling direction, and are named. In this step, the design (X, Y, Z) coordinate data at the position corresponding to the name of such a grid point is input. Note that S is the initial of Support (end fulcrum), G is the initial of Girder (girder), P is the initial of Pier (intermediate fulcrum), and C is the initial of Cross (lateral girder grid point). FIG. 6 shows a state where the total station 30 is measuring the target prism 20 mounted on the pole 25 set at the grid point C4 - G2.

[0035] Also, in step S1001, since the user is required to set the grid points to be actually measured among the input grid points, correspondingly, in this step, the user selects the grid points to be actually measured. Next, proceed to step S1002 and end the process.

[0036] Returning to FIG. 4, when the button UI2 is tapped, the machine point setting process is executed in the tablet terminal device 12. FIG. 7 is a diagram showing a flowchart of the total station 30 machine point setting process by the tablet terminal device (information processing device) 12. This machine point setting process is preferably performed every day when the total station 30 performs measurement.

[0037] In step S1100, when the machine point setting process of the total station 30 is started, in the subsequent step S1101, the machine point of itself is determined by measuring a point whose coordinates are known in the total station 30 and this is stored. As a method for obtaining the machine point of the total station 30 itself, a well-known method can be appropriately adopted.

[0038] Subsequently, in step S1102, the user is prompted to input temperature data, etc. on the day when the total station 30 performs measurement, and the process of storing the input data is executed. FIG. 8 is a diagram showing an example of the user interface screen displayed on the tablet terminal device 12 in step S1102. Through such a screen, the user is prompted to input information related to weather and temperature, information related to the measurement type, and information related to the digit temperature.

[0039] UI of the user interface screen in FIG. 8 11As shown, in the formed shape measurement system 1 according to the present invention, in particular, information related to the digit temperature is input and used for data correction as described later. In this example, although it is configured such that the user manually inputs the digit temperature, a temperature sensor (not shown) is provided at the grounding point of the pole 25, and the digit temperature acquired by this sensor is transmitted to the tablet terminal device 12 by communication and utilized as information of the screen UI 11 can also be configured. Subsequently, in step S1103, the process ends.

[0040] Returning to FIG. 4, when the button UI3 is tapped, the tablet terminal device 12 executes the reference point setting process. FIG. 9 is a diagram showing a flowchart of the reference point setting process of the level measuring instrument 40 by the tablet terminal device (information processing device) 12.

[0041] In step S1200, when the reference point setting process of the level measuring instrument 40 is started, the process then proceeds to step S1201, where the level measuring instrument 40 measures a known level to determine its own level and stores it. In step S1202, similar to the example of the total station, the user is prompted to input information such as weather conditions, and the information input by the user is stored. The process proceeds to step S1203 and ends.

[0042] Returning to FIG. 4, when the button UI4 is tapped, the tablet terminal device 12 executes the measured data measurement process by the total station 30. The process of acquiring the measured data by this total station 30 is a process in which an operator holds the pole 25 with the target prism 20 attached to the grid point to be measured (for example, grid point C4 - G2) and checks the horizontality of the target prism 20. Also, the process of acquiring the measured data is performed for each grid point to be measured. Therefore, when the measured data of a certain grid point is acquired, the operator moves to the next grid point, stands the pole 25 at the grid point again, and acquires the measured data.

[0043] Figure 10 is a flowchart showing the acquisition process of the measured data by the total station 30 of the formed shape measurement system 1 according to the embodiment of the present invention. This flowchart illustrates the collaborative processing by the tablet-type terminal device 12, the total station 30, and the remote controller 50. Further, this flowchart is premised on being executed for each grid point to be measured.

[0044] When the button UI4 in FIG. 4 is tapped, on the tablet-type terminal device 12, a user interface screen as shown in FIG. 11 is displayed. In the process on the tablet-type terminal device 12, in step S1301, the design data corresponding to the grid point name to be measured is acquired. This design data is the one input in the previous design setting process. Also, the grid point name to be measured may be manually input by the operator, or the next grid point may be automatically input every time the actual measurement is completed. The UI in FIG. 11 21 shows that the grid point to be measured is C4-G2. Also, based on the design data of this grid point to be measured being C4-G2, a dashed circle as shown in the UI 23 is displayed. The center of this dashed circle is the (X, Y) coordinates among the (X, Y, Z) coordinates of the design data.

[0045] In the total station 30, in step S2001, while automatically tracking the target prism 20, its coordinates are measured. In the next step S2002, the measured coordinates are transmitted to the tablet-type terminal device 12. In the total station 30, the loop of step S2001 and step S2002 is repeated.

[0046] In the tablet-type terminal device 12, in step S1302, based on the measured coordinates received from the total station 30, a graphical user interface screen is generated. In this generation process, a solid circle screen display as shown in the UI 24 is performed. The UI 24The center of the solid-line circle shown is the (X, Y) coordinates among the (X, Y, Z) coordinates of the measured data transmitted from the total station 30. It is assumed that the operator checks on the user interface screen shown in FIG. 11 that the dashed-line circle and the solid-line circle overlap, and presses a switch (not shown) of the remote controller 50. The overlapping of the dashed-line circle and the solid-line circle means that the pole 25 is in a vertical state.

[0047] Now, in the remote controller 50, at step S4001, it is determined whether or not the pressing of a switch (not shown) is detected. If this determination is NO, the process loops back to step S4001 to make the determination again. However, if the determination at step S4001 becomes YES, the loop is exited, and the process proceeds to step S4002 to generate a trigger signal and transmit this to the tablet terminal device 12. Note that in this example, an example is shown in which the pressing of a switch (not shown) of the remote controller 50 generates a trigger signal. However, it is also configured such that by pressing the UI 22 (“Measurement” button) on the user interface screen of the tablet terminal device 12, a trigger signal is generated and transmitted.

[0048] In the tablet terminal device 12, when the trigger signal is received, at step S1303, the measurement coordinate data from the total station 30 is acquired as the measured data. Subsequently, at step S1304, the distance difference D1 between the (design data) and the (measured data) is calculated.

[0049] In step S1305, it is determined whether the calculated D1 is greater than or equal to a predetermined value. If the determination in step S1305 is YES, since the deviation between (design data) and (measured data) is large and there is a possibility that meaningless data has been acquired as measured data, the process proceeds to step S1306 to give an error notification. The method of error notification by the tablet terminal device 12 may be any method, such as notification by voice, notification by screen display, or notification by vibration that causes the tablet terminal device 12 to vibrate.

[0050] If the determination in step S1305 is NO, the measurement coordinate data from the total station 30 is stored as error-free formal measured data as measured data.

[0051] Returning to FIG. 4, when the button UI5 is tapped, in the tablet terminal device 12, the measurement process of the measured data by the level measuring instrument 40 is executed. The process of acquiring the measured data by this level measuring instrument 40 is a process in which an operator places the barcode staff 45 at the grid point to be measured (for example, grid point C4-G2). Also, the process of acquiring the measured data is performed for each grid point to be measured. Therefore, when the measured data of a certain grid point is acquired, the operator moves to the next grid point and places the barcode staff 45 at the grid point again to acquire the measured data.

[0052] FIG. 12 is a flowchart showing the process of acquiring measured data by the level measuring instrument 40 of the formed shape measurement system 1 according to the embodiment of the present invention. This flowchart illustrates the collaborative process by the tablet terminal device 12, the level measuring instrument 40, and the remote controller 50. Also, this flowchart is premised on being executed for each grid point to be measured.

[0053] In the processing of the tablet terminal device 12, in step S1401, Z-direction design data corresponding to the grid name to be measured is acquired. This design data is the one input in the previous design setting process. If there is already measured data measured by the total station 30, the measured data may be used.

[0054] In the level measuring instrument 40, in step S3101, the barcode staff 45 is measured. In the next step S3102, the measured height data is transmitted to the tablet terminal device 12. In the level measuring instrument 40, the loop of step S3101 and step S3102 is repeated.

[0055] In the tablet terminal device 12, in step S1402, height data is transmitted from the level measuring instrument 40.

[0056] In the remote controller 50, in step S4101, it is determined whether or not the pressing of a switch (not shown) is detected. If this determination is NO, the loop is repeated to make the determination again in step S4101. However, if the determination in step S4101 becomes YES, the loop is exited, and the process proceeds to step S4102 to generate a trigger signal and transmit this to the tablet terminal device 12. In this example, an example of generating a trigger signal by pressing a switch (not shown) of the remote controller 50 is shown. However, it is also configured to generate a trigger signal by input from the user interface screen of the tablet terminal device 12 and transmit this.

[0057] In the tablet terminal device 12, when receiving the trigger signal, in step S1403, the height data from the level measuring instrument 40 is acquired as measured data. Subsequently, in step S1404, the distance difference D2 between (the Z-direction design data) and (the measured height data) is calculated.

[0058] In step S1405, it is determined whether the calculated D2 is greater than or equal to a predetermined value. If the determination in step S1405 is YES, since the deviation between the design height data and the measured height data is large and there is a possibility that meaningless data has been obtained as the measured data, the process proceeds to step S1406 to give an error notification. The method of error notification by the tablet terminal device 12 may be any method, such as notification by voice, notification by screen display, or notification by vibration that causes the tablet terminal device 12 to vibrate.

[0059] If the determination in step S1405 is NO, the height data from the level measuring instrument 40 is stored as formal height data without errors.

[0060] Next, a process of calculating the as-built shape based on the measured data at the grid points in the upper part work acquired and collected by the tablet terminal device 12 will be described. Such a process of calculating the as-built shape may be executed in the background while the tablet terminal device 12 is running the as-built shape measurement system 1 according to the present invention.

[0061] When the as-built shape calculation process is started in step S1500, subsequently, in step S1501, the measured data measured by the total station 30 at each grid point, the measured height data measured by the level measuring instrument 40, and the input girder temperature data are acquired.

[0062] In step S1502, the height data (Z) in the measured data (X, Y, Z) by the total station 30 is replaced with the measured height data by the level measuring instrument 40, and this is used as new data. In this specification, this new data will be referred to as "level-corrected measured data". In the present invention, such a process is adopted because the height data by the level measuring instrument 40 is more reliable than the height data by the total station 30.

[0063] Next, in step S1303, each value of the span length, total length, camber, sag, reference height, and width is calculated from the measured data of level correction and the temperature data. Hereinafter, each calculation method will be described with reference to FIG. 14. ● Regarding the span length Taking the span length between the grid points G1-S1 and G1-S2 as shown in FIG. 14(a) as an example. In this case, the span length L1 is L1 = {(X2 - X1) 2 + (Y2 - Y1) 2 + (Z2 - Z1) 2} 1 / 2 and can be calculated by. ● Regarding the total length The total length is the sum of consecutive span lengths. Taking FIG. 14(b) as an example, the total length L is L = L1 + L2 + L3 + ···· and can be calculated as such. ● Regarding the camber Taking the grid point G1-C4 existing between the grid points G1-S1 and G1-S2 as shown in FIG. 14(c) as an example for explanation. In calculating this camber, the coordinate transformation shown in FIG. 14(d) is performed. In this coordinate transformation, the grid point G1-S1 is moved to the origin, and a rotation of θ is applied so that the straight line passing through the grid points G1-S2 and G1-C4 becomes the Y-axis. At this time, the camber can be calculated as follows. X2’ = X2 - X1 Y2’ = Y2 - Y1 θ = arctan(Y2’ / X2’) × (-1) X3’ = X3 - X1 Y3’ = Y3 - Y1 X3’’ = Y3’ × sinθ - X3’ × cosθ Y3’’ = Y3’ × cosθ - X3’ × sinθ (Camber) = Y3’’ × (camber sign) Here, (camber sign) = -1: In the case of the plus direction (see FIG. 14(c)) (Camber sign) = +1: In the case of the minus direction (see FIG. 14(c)) ● Regarding the sag (when the upper worker is a bridge erection worker) Sag = (Z coordinate of measured value) - (Z coordinate of designed value) ●Regarding the reference height (when the upper work is the floor slab work) (Reference height) = (Z coordinate of measured value) - (Z coordinate of designed value) ●Regarding the width It is calculated by the distance between two points in the width direction of the upper work. ●Regarding the correction by girder temperature (temperature data) The correction by girder temperature (temperature data) is applied to the span length and the total length.

[0064] First, the temperature change amount δ is δ = α × (T - T o ) × L and can be obtained by this. Here α: Coefficient of thermal expansion = 1.22 × 10 -5 [mm / ℃] T: Girder temperature = (measured value) [℃] ··· Input by the user interface screen T o : Designed temperature = 20 [℃] L: Girder length = designed value [mm] ··· Obtained from the design data. That is.

[0065] As an example, when the girder temperature is 40.3℃, the designed temperature is 20℃, and the designed girder length is 50m, the temperature change amount δ is δ = 1.22 × 10 -5 × (40.3 - 20.0) × 50000 = 12.4 [mm].

[0066] When the value of the span length (or the total length) based on the measurement is L', the measured value corrected by the girder temperature (temperature data) is (L' - 12.4) [mm].

[0067] Now, returning to FIG. 4, when the button UI6 is tapped, the process of form output is executed in the tablet terminal device 12. FIG. 15 is a diagram showing a flowchart of the form output process in the form measurement system 1 according to the embodiment of the present invention.

[0068] In step S1600, when the form output process is started, the process then proceeds to step S1601, where the calculated values of the bay length, total length, camber, sag, reference height, and width obtained in the form calculation process are acquired. In the next step S1602, these calculated values (all calculated values, any calculated value, or any combination of calculated values) are output in the file format of spreadsheet software.
