Description

The present invention relates to a system for measuring the completed form of superstructures in bridge construction using a total station or the like, and enabling the creation of reports based on the measured data.

At bridge construction sites, values such as the span length, overall length, clearance, camber, reference height, and width of the bridge are calculated based on the coordinates of each grid point in the constructed superstructure (bridge erection work, deck work, etc.), and are used in as-built inspections. Recently, a system has been proposed that uses a total station to measure the as-built form of a bridge.

For example, paragraph number [0031] of cited document 1 (JP Patent Publication No. 2017-123061) describes that a measurement method such as measurement using a total station can be used to generate 3D visualization data of the completed shape.

JP 2017-123061 A

Previously, when measuring the coordinates of each grid point in the superstructure using a total station, multiple workers were needed, which was a labor-intensive task. In addition, when creating a report on the completed form (completed form report) of each value of the bridge's span length, total length, clearance, camber, reference height, width, etc. based on the coordinates of each grid point measured by a total station, there was also the problem that the report creation work required manpower and labor.

In order to solve the above problems, the completed form measurement system of the present invention is a system for measuring the completed form of a superstructure in bridge construction, and comprises a total station which automatically tracks a target prism and measures coordinate data of the target prism, a remote controller which commands the total station to perform measurements, an information processing device which stores design data corresponding to grid points on the superstructure, commands the total station and receives coordinate data from the total station, a pole which holds the target prism and the information processing device, a level measuring instrument, and a barcode staff which is read by the level measuring instrument, and based on a trigger signal from the remote controller, the coordinate data measured by the total station is imported into the information processing device as actual measurement data, the information processing device receives height data from the level measuring instrument, the information processing device corrects the actual measurement data based on the height data, and the level corrected actual measurement data is stored in the information processing device.

The completed form measurement system according to the present invention also has a user interface screen that displays whether the pole is approximately vertical when the information processing device sets up a pole at a grid point.

The finished product measurement system of the present invention also reports an error when the actual measurement data deviates from the design data by a predetermined value or more.

In addition, in the finished product measurement system according to the present invention, the information processing device overwrites and corrects the actual measurement data with height data, and the data is stored in the information processing device as level-corrected actual measurement data.

In addition, in the finished product measurement system according to the present invention, the information processing device has a user interface screen with at least a temperature input field, the temperature input in the input field is stored as temperature data, and at least the span length, total length, clearance, warp, reference height, and width values are calculated from the level-corrected actual measurement data and the temperature data.

In addition, in the finished product measurement system according to the present invention, the information processing device transmits each of the values to another information processing device.

In addition, in the finished product measurement system according to the present invention, the information processing device outputs each of the values to spreadsheet software.

The completed form measurement system of the present invention is a system for measuring the completed form of superstructures in bridge construction, and includes a total station that automatically tracks a target prism and measures the coordinate data of the target prism, a remote controller that commands the total station to perform measurements, an information processing device that stores design data corresponding to a specified position on the superstructure, commands the total station, and receives coordinate data from the total station, and a pole that holds the target prism and the information processing device.

The following describes an embodiment of the present invention with reference to the drawings. FIG. 1 is a diagram showing an outline of the configuration of a completed form measurement system 1 according to an embodiment of the present invention. The completed form measurement system 1 according to the present invention is used to determine various values such as the span length, overall length, clearance, warp, reference height, and width of a bridge in the completed form management of the superstructure (bridge erection work, deck work, etc.) constructed in bridge construction. In the completed form measurement system 1 according to the present invention, a total station 30 and a level measuring device 40 are used to measure and obtain coordinate data of the grid points in the superstructure that are set at the bridge design stage, and the coordinate data is used to calculate the various values.

The coordinate data measured by the total station 30 is originally the position coordinates of the target prism 20 that is set up vertically at the grid point in the superstructure, but in this specification it is defined as data relating to the position coordinates of the grid point in the superstructure minus the height of the pole 25 to which the target prism 20 is attached. In addition, the height data measured by the level measuring instrument 40 is also defined as data relating to the height of the grid point in the superstructure at that position. In summary, the measurement data by the total station 30 is the coordinate data (X, Y, Z) of the grid point in the superstructure, and the measurement data by the level measuring instrument 40 is the height data (Z) of the grid point in the superstructure.

The completed form measurement system 1 according to the present invention is intended to use a total station 30 and a level measuring instrument 40 to perform one-man surveying of completed form measurement at the bridge superstructure site and to automatically create and output completed form reports. In addition, an information processing device such as a tablet terminal device 12 is used in conjunction with the total station 30 and level measuring instrument 40 so that the difference between the design value (also called "design data") and the actual measurement value (also called "actual measurement data") can be confirmed on the spot where the measurement is performed, and so that the measurement results of the entire girder (bridge span length, overall length, clearance, warp, reference height, and width) can also be confirmed. In addition, for example, when surveying using the total station 30, a remote controller 50 is provided that enables the total station 30 to operate the distance measurement operation with a button switch in order to perform distance measurement operations while maintaining the horizontality of the target prism 20.

In the finished product measurement system 1 according to the present invention, it is assumed that the total station 30 and level measuring instrument 40 are capable of transmitting and receiving data to and from information processing devices such as a tablet terminal device 12 and a personal computer 13.

The completed form measurement system 1 of the present invention can be configured to display the measurement results and create and print completed form reports on a tablet terminal device 12 carried by a worker performing one-man surveying, but it can also be configured to transmit data held by the tablet terminal device 12 to another device (an information processing device such as the tablet terminal device 12 shown on the right side of Figure 1 or a personal computer 13) so that the measurement results can be displayed and completed form reports can be created and printed on the other device.

For this purpose, all tablet-type terminal devices 12 and personal computers 13 in FIG. 1 can be connected so as to enable data communication via a communication line 15, and data acquired by the tablet-type terminal devices 12 carried by workers can be shared on a cloud server 18. Note that people who operate the information processing devices that execute the finished form measurement system 1 according to the present invention, including the tablet-type terminal devices 12, may be referred to as "users," including workers.

Next, we will explain the measurement mode using the completed form measurement system 1 configured as described above. Figure 2 is a diagram showing the state of a bridge construction site where measurements are being performed by a total station 30 using the completed form measurement system 1 according to an embodiment of the present invention.

A target prism 20 is attached to one end of the pole 25. The target prism 20 is automatically tracked by the total station 30, and the total station 30 measures its position coordinates. It is also assumed that a worker will hold the pole 25 so that the other end of the pole 25 is positioned above a grid point in the superstructure 5.

A tablet-type terminal device 12 is attached to the pole 25 by a mounting member 26, and a worker can operate the remote controller 50 while referring to the display device of this tablet-type terminal device 12. When the total station 30 performs measurements, accurate measurements are possible if the pole 25 is vertical (in other words, the target prism 20 is horizontal) when the pole 25 is set up at the grid point. The worker adjusts the pole 25 while holding it so that the target prism 20 remains horizontal, and operates the remote controller 50 at the appropriate moment, so that the grid point coordinate data is imported into the tablet-type terminal device 12. The various processes for this will be described later.

In the finished product measurement system 1 according to the present invention, in addition to the target prism 20, a tablet terminal device 12 is attached to the pole 25, which greatly contributes to the worker keeping the target prism 20 horizontal.

Next, the manner in which measurements are taken by the level measuring device 40 of the completed form measurement system 1 will be described. FIG. 3 is a diagram showing a bridge construction site where measurements are being taken by the level measuring device 40 in the completed form measurement system 1 according to an embodiment of the present invention. As shown in the figure, each gate point in the superstructure 5 is given a gate point name such as C4-G2. The worker shown in FIG. 3 holds the barcode staff 45 horizontally above the position of C4-G2, and operates the tablet terminal device 12 and remote controller 50 to input the gate point height data for gate point C4-G2 into the tablet terminal device 12.

The coordinate data (X, Y, Z) of the grid points in the superstructure can also be obtained by the total station 30, but the height data (Z) obtained by the level measuring device 40 may be considered to be more accurate. Therefore, in the completed form measurement system 1 according to the present invention, when the latter data is obtained, the Z value of the former coordinate data (X, Y, Z) is corrected by overwriting it with the latter data.

Next, the processing and operation of the finished product measurement system 1 according to the present invention will be described with reference to the display on the display device of the tablet terminal device 12 carried by the worker. Figure 4 is a diagram showing an example of a user interface screen on the display device of the tablet terminal device (information processing device) 12.

The display device used in the tablet terminal device 12 is usually a touch panel display, and the worker can perform input operations by touching the user interface screen with his or her fingers. Commonly known input operations called "tap," "double tap," "long tap," "flick," "swipe," and "pinch" are also used in the system according to the present invention.

For example, when a worker taps a button displayed on the user interface screen shown in Fig. 4, a command marked on the button is executed. In the completed form measurement system 1 according to the present invention, when the button _UI1 is tapped, a design setting process is executed on the tablet terminal device 12.

Figure 5 is a diagram showing a flowchart of the design and configuration process by the tablet terminal device 12. When the design and configuration process is started in step S1000, the process proceeds to step S1001.

In this step S1001, the user is prompted to input information about the design of the superstructure to be designed. In response, the user inputs design data corresponding to the measurement point names in the superstructure (design values of the coordinate data (X, Y, Z) of the measurement point).

Figure 6 is an example of a plan view showing the grid points of the superstructure. The grid points are defined and named as the intersections of a line Gn along the road's travel direction, and lines Sn, Cn, and Pn (where n is a natural number) perpendicular to the travel direction. In this step, the design (X, Y, Z) coordinate data for the positions corresponding to the names of such grid points is input. Note that S is the initial letter of Support (end support), G is the initial letter of Girder (beam), P is the initial letter of Pier (intermediate support), and C is the initial letter of Cross (cross beam grid point). Figure 6 illustrates how the total station 30 measures the target prism 20 attached to a pole 25 erected at grid point C4-G2.

In step S1001, the user is prompted to select the points at which measurements will actually be taken from among the points entered, and in response, the user selects the points at which measurements will actually be taken in this step. Next, the process proceeds to step S1002, where the process ends.

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 machine point setting process of the total station 30 by the tablet terminal device (information processing device) 12. This machine point setting process is preferably performed every day that measurement is performed by the total station 30.

In step S1100, the process of setting the mechanical point of the total station 30 is started. In the following step S1101, the total station 30 measures a point whose coordinates are known, thereby determining and storing its own mechanical point. As a method for acquiring the mechanical point of the total station 30 itself, any well-known method can be appropriately adopted.

In the next step S1102, the user is prompted to input temperature data and the like for the day that the measurement is to be performed by the total station 30, and the input data is stored. FIG. 8 is a diagram showing an example of a user interface screen displayed on the tablet terminal device 12 in step S1102. This screen prompts the user to input information related to the weather and temperature, information related to the measurement type, and information related to the digit temperature.

As shown in the UI ₁₁ of the user interface screen in Fig. 8, in the finished product measurement system 1 according to the present invention, information relating to the girder temperature is input in particular and used for data correction as described below. Note that, in this example, the user is configured to manually input the girder temperature, but it is also possible to provide a temperature sensor (not shown) at the point where the pole 25 is grounded, and to transmit the girder temperature acquired by this sensor to the tablet terminal device 12 via communication and use it as information on the screen UI _11. In the next step S1103, the process ends.

Returning to Fig. 4, when the button _UI3 is tapped, a reference point setting process is executed in the tablet-type terminal device 12. Fig. 9 is a diagram showing a flowchart of a reference point setting process of the level measuring instrument 40 by the tablet-type terminal device (information processing device) 12.

In step S1200, the process of setting the reference point of the level measuring device 40 is started, and then the process proceeds to step S1201, where the level measuring device 40 measures a known level to determine its own level and executes a process of storing it. In step S1202, similar to the example of the total station, the user is prompted to input weather conditions, etc., and the information input by the user is stored. The process proceeds to step S1203, where it ends.

Returning to Fig. 4, tapping the button _UI4 causes the tablet terminal device 12 to execute measurement processing of actual measurement data by the total station 30. This processing of acquiring actual measurement data by the total station 30 is performed by an operator holding the pole 25 to which the target prism 20 is attached at the grid point to be measured (for example, grid point C4-G2) while checking the level of the target prism 20. Furthermore, the processing of acquiring actual measurement data is performed for each grid point to be measured. Therefore, once acquisition of actual measurement data for a certain grid point has been performed, the operator moves to the next grid point, sets up the pole 25 at the grid point again, and acquires actual measurement data.

Figure 10 is a flowchart showing the process of acquiring actual measurement data by the total station 30 of the finished form measurement system 1 according to an embodiment of the present invention. This flowchart illustrates the collaborative process between the tablet terminal device 12, the total station 30, and the remote controller 50. This flowchart is also based on the premise that it is executed for each measurement point to be measured.

When the button UI ₄ in FIG. 4 is tapped, the tablet terminal device 12 displays a user interface screen as shown in FIG. 11. In the process in the tablet terminal device 12, in step S1301, design data corresponding to the name of the measurement target is acquired. This design data is input in the previous design setting process. The name of the measurement target may be input manually by an operator, or the next measurement point may be automatically input each time the actual measurement is completed. The UI ₂₁ in FIG. 11 shows that the measurement target is C4-G2. Based on the design data of the measurement target is C4-G2, a dashed circle as shown in the UI ₂₃ is displayed. The center of this dashed circle is the (X, Y) coordinate of the (X, Y, Z) coordinate of the design data.

In the total station 30, in step S2001, the target prism 20 is automatically tracked and its coordinates are measured. In the next step S2002, the measured coordinates are transmitted to the tablet terminal device 12. In the total station 30, a loop of steps S2001 and S2002 is repeated.

In the tablet terminal device 12, in step S1302, a graphical user interface screen is generated based on the measurement coordinates received from the total station 30. In this generation process, a solid circle as shown in UI ₂₄ is displayed on the screen. The center of the solid circle shown in UI ₂₄ is the (X, Y) coordinates of the (X, Y, Z) coordinates of the actual measurement data transmitted from the total station 30. It is assumed that the worker confirms that the dashed circle and the solid circle overlap on the user interface screen shown in FIG. 11 and then presses a switch (not shown) of the remote controller 50. The dashed circle and the solid circle overlap means that the pole 25 is in a vertical state.

In the remote controller 50, in step S4001, it is determined whether or not pressing of a switch (not shown) has been detected. If the determination is NO, the process loops to make a determination in step S4001 again, but if the determination in step S4001 is YES, the process exits this loop and proceeds to step S4002, where a trigger signal is generated and transmitted to the tablet-type terminal device 12. Note that, although this example shows an example in which a trigger signal is generated by pressing a switch (not shown) of the remote controller 50, it is also configured to generate and transmit a trigger signal by pressing UI ₂₂ (the "Measure" button) on the user interface screen of the tablet-type terminal device 12.

When the tablet terminal device 12 receives the trigger signal, in step S1303, it acquires the measurement coordinate data from the total station 30 as actual measurement data. Then, in step S1304, it calculates the difference D1 in distance between (design data) and (actual measurement data).

In step S1305, it is determined whether the calculated D1 is equal to or greater than a predetermined value. If the determination in step S1305 is YES, there is a large discrepancy between the (design data) and the (actual measurement data), and it is possible that meaningless data has been acquired as the actual measurement data, so the process proceeds to step S1306, where an error is notified. The method for notifying the error by the tablet-type terminal device 12 may be any method, and may include a sound notification, a notification by a screen display, or a notification by vibration that vibrates the tablet-type terminal device 12.

If the determination in step S1305 is NO, the measurement coordinate data from the total station 30 is stored as official actual measurement data without any errors.

Returning to FIG. 4, tapping the button _UI5 causes the tablet terminal device 12 to execute a measurement process of actual measurement data by the level measuring instrument 40. This process of acquiring actual measurement data by the level measuring instrument 40 is performed by an operator who places the barcode staff 45 at the grid point of the measurement target (e.g., grid point C4-G2). The process of acquiring actual measurement data is performed for each grid point of the measurement target. Therefore, once the actual measurement data of a certain grid point has been acquired, the operator moves to the next grid point, places the barcode staff 45 at the grid point again, and acquires the actual measurement data.

Figure 12 is a flowchart showing the process of acquiring actual measurement data by the level measuring device 40 of the finished shape measurement system 1 according to an embodiment of the present invention. This flowchart illustrates the collaborative process between the tablet terminal device 12, the level measuring device 40, and the remote controller 50. This flowchart is also based on the premise that it is executed for each measurement point to be measured.

In the processing in the tablet terminal device 12, in step S1401, Z-direction design data corresponding to the grid point name to be measured is acquired. This design data was input in the previous design setting process. If actual measurement data measured by the total station 30 already exists, this actual measurement data may be used.

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, a loop of steps S3101 and S3102 is repeated.

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

In the remote controller 50, in step S4101, it is determined whether pressing of a switch (not shown) has been detected. If the determination is NO, the process loops to make a determination in step S4101 again, but if the determination in step S4101 is YES, the process exits this loop and proceeds to step S4102, where a trigger signal is generated and sent to the tablet-type terminal device 12. Note that while this example shows an example in which a trigger signal is generated by pressing a switch (not shown) on the remote controller 50, it is also configured to generate and send a trigger signal in response to input from a user interface screen of the tablet-type terminal device 12.

When the tablet terminal device 12 receives the trigger signal, in step S1403, the height data from the level measuring device 40 is acquired as the actually measured data. Next, in step S1404, the difference D2 in the distance between (the design data in the Z direction) and (the actually measured height data) is calculated.

In step S1405, it is determined whether the calculated D2 is equal to or greater than a predetermined value. If the determination in step S1405 is YES, there is a large discrepancy between the design height data and the actually measured height data, and it is possible that meaningless data has been acquired as the actual measured data, so the process proceeds to step S1406, where an error is notified. The method for notifying the error by the tablet-type terminal device 12 may be any method, and may include a sound notification, a notification by a screen display, or a notification by vibration that vibrates the tablet-type terminal device 12.

If the determination in step S1405 is NO, the height data from the level measuring device 40 is stored as correct height data without any errors.

Next, we will explain the process of calculating the completed form based on the actual measurement data at the grid points of the superstructure that is acquired and collected by the tablet terminal device 12. This process of calculating the completed form can be executed in the background while the tablet terminal device 12 is executing the completed form measurement system 1 according to the present invention.

In step S1500, the finished form calculation process is started, and in the following step S1501, the actual measurement data measured by the total station 30 at each grid point, the actual height data measured by the level measuring device 40, and the input girder temperature data are acquired.

In step S1502, the height data (Z) in the actual measurement data (X, Y, Z) from the total station 30 is replaced with the actual measurement height data from the level measuring instrument 40, and this is used as new data. This new data is referred to in this specification as "level-corrected actual measurement data." This type of processing is adopted in the present invention because the height data from the level measuring instrument 40 is more reliable than the height data from the total station 30.

In the next step S1303, the span length, overall length, alignment, warp, reference height, and width are calculated from the level-corrected measured data and the temperature data. Each calculation method will be described below with reference to FIG.
Span length Let us take the span length between the grid points G1-S1 and G1-S2 as shown in Figure 14(a) as an example. The span length L1 in this case is:
L1={(X2-X1) ² +(Y2-Y1) ² +(Z2-Z1) ² } ^1/2
It can be calculated by:
● Total length The total length is the sum of the lengths of consecutive spans. Taking Figure 14(b) as an example, the total length L is L = L1 + L2 + L3 + ...
It can be calculated as follows:
● Regarding the street We will explain this by taking as an example the grid point G1-C4 between grid points G1-S1 and G1-S2 as shown in Figure 14(c). In calculating this street, the coordinate transformation shown in Figure 14(d) is performed. In this coordinate transformation, the grid point G1-S1 is moved to the origin, and a θ rotation is performed so that the straight line passing through grid points G1-S2 and G1-C4 becomes the Y-axis. In this case, the street 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
(pass) = Y3'' x (pass code)
Here, (pass code) = -1: in the positive direction (see FIG. 14(c)).
(pass code) = +1: in the negative direction (see FIG. 14(c))
● About warping (when the superstructure is bridge construction)
(Warp) = (actual Z coordinate) - (design Z coordinate)
●About the reference height (when the superstructure is deck construction)
(Reference height) = (actual measured Z coordinate) - (designed Z coordinate)
●The width is calculated based on the distance between two points on the superstructure in the width direction.
Correction based on girder temperature (temperature data) Correction based on girder temperature (temperature data) is applied to span length and total length.

First, the temperature change δ is
δ=α×(T-T _o )×L
Here,
α: Coefficient of thermal expansion = 1.22×10 ^-5 [mm/°C]
T: Digit temperature = (measured value) [°C] ... input via the user interface screen T _o : Design temperature = 20 [°C]
L: Beam length = design value [mm]...obtained from design data.
It is.

For example, when the girder temperature is 40.3°C, the design temperature is 20°C, and the design girder length is 50m, the temperature change δ is
δ=1.22× ^10-5 ×(40.3-20.0)×50000
= 12.4 [mm].

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

4, when the button UI ₆ is tapped, a process of outputting a form is executed in the tablet terminal device 12. Fig. 15 is a diagram showing a flowchart of the process of outputting a form in the finished shape measurement system 1 according to the embodiment of the present invention.

In step S1600, the report output process is started, and then the process proceeds to step S1601, where the calculated values of span length, total length, alignment, warp, reference height, and width obtained in the completed form calculation process are obtained. In the next step S1602, these calculated values (all calculated values, any calculated value, or a combination of any calculated values) are output in a file format for spreadsheet software. An example of such a completed form report is shown in Figure 16. The process ends in step S1603.

As described above, the completed form measurement system 1 of the present invention is a system for measuring the completed form of a superstructure 5 in bridge construction, and comprises a total station 30 that automatically tracks a target prism 20 and measures the coordinate data of the target prism 20, a remote controller 50 that commands the total station 30 to perform measurement, an information processing device (tablet type terminal device 12) that stores design data corresponding to a predetermined position on the superstructure 5 and commands the total station while receiving coordinate data from the total station, and a pole 25 that holds the target prism 20 and the information processing device (tablet type terminal device 12). According to the completed form measurement system 1 of the present invention, one-man operation is possible when performing measurements at the bridge construction site, and furthermore, after measurement, a report can be created using the information processing device, making it possible to significantly reduce manpower and effort.
