It is configured to be able to wirelessly communicate with a server computer (hereinafter simply referred to as a server) 3 provided as an online storage service using. The surveying position display device 4 and the surveying machine 5 are connected via a portable wireless LAN router 7 that can be carried at a surveying site, for example. Thereby, even if it is a case where it cannot connect with a public internet line like a tunnel, underground, a high place, etc., communication of the surveying position display apparatus 4 and the surveying machine 5 is securable. The surveying position display device 4 is connected to the computer 2 and the server 3 from the wireless LAN router 7 via the network 6. The computer 2 and the server 3 are CPUs, ROMs, RAMs, HDDs, etc. as arithmetic means provided as hardware resources, input means such as keyboards and mice, display means such as monitors, and communication with network lines. The communication means which enables is provided.

  FIG. 2 is a hardware configuration diagram of the surveying position display device 4. The surveying position display device 4 is a portable computer and is carried along with the surveying machine 5 to the surveying site. The surveying position display device 4 enables communication with a CPU 10 as a calculation means provided as hardware resources, a storage means 12 such as a ROM, a RAM, an HDD, an operation panel 14 provided as an input / output means, and a network line. An internal bus 18 for connecting the communication means 16 and the like.

  The surveying position display device 4 is configured by a tablet computer in which one hardware resource is accommodated in a plate-shaped housing, for example. The storage unit 12 stores a survey position display program that causes the tablet computer (CPU 10) to function as the survey position display device 4. Then, the CPU 10 functions as each unit described later by using the RAM as a work area and executing the surveying position display program stored in the storage unit 12.

  The operation panel 14 is a display input unit including a touch panel in which a display unit such as a liquid crystal monitor for displaying information to the surveying operator and an input unit for inputting a command by the surveying operator are integrated.

  FIG. 3 is a block diagram showing an embodiment of the survey position display device. As shown in the figure, the surveying position display device 4 includes an input operation receiving means 20, an observation execution command output means 22, a drawing acquisition means 24, a drawing display means 26, a machine point display means 28, and a survey point. The display means 30, the observation information calculation display means 32, and the observation drawing output means 34 are provided.

  The input operation receiving means 20 receives an operation on the operation panel 14 by a surveying operator as an input operation. For example, when a surveying operator taps a character or button displayed on the operation panel 14, it is recognized that the character or button is selected.

  The observation execution command output means 22 urges the surveying operator to select a surveying method such as radio surveying or pile driving surveying, and outputs the selected radio surveying or pile driving survey command to the surveying machine 5. Specifically, the observation execution command output means 22 displays buttons such as “coordinate surveying” and “stakeout surveying” on the operation panel 14 to prompt the surveying operator to select one of the surveying methods.

  The drawing acquisition unit 24 accesses the server 3 via, for example, the network 6 and the wireless LAN router 7 and downloads drawing data stored in the server 3, thereby drawing data from the server 3 into the survey position display device 4. To get. Specifically, the drawing acquisition means 24 accesses the server 3, displays a folder storing the drawing data of the server 3 on the operation panel 14, and selects drawing data necessary for surveying work from the displayed folder. The surveying operator is prompted to download the selected drawing data from the server 3 to the surveying position display device 4. The downloaded drawing data is stored in the storage unit 12.

  The drawing data is created based on, for example, a three-dimensional design drawing drawn by CAD software at the beginning of the design of a feature such as a building by the computer 2. For example, for drawing data, create a two-dimensional plan view such as a horizontal plane or vertical plane from a three-dimensional design drawing, and leave only the contents necessary for surveying from the plan view. It is created as a surveying drawing by processing to exclude. The survey drawing is created by a drawing coordinate system. The drawing coordinate system is a coordinate system that is set with the horizontal direction of the screen as the X axis and the vertical direction as the Y axis when displayed on the monitor by CAD software. Note that, for example, information on how many times the X axis is shifted clockwise from true north is linked to the survey drawing. The drawing data created by the computer 2 is uploaded to the server 3 described above. In addition to the above, the drawing data may be any of a completed plan view, a partial plan view, and the like.

  As described above, by creating the surveying drawing based on the design drawing as the basic drawing, the data capacity of the drawing data is reduced, so the processing speed when the surveying position display device 4 is configured by a tablet computer is improved. can do. In addition, since the amount of information displayed on the operation panel 14 is reduced, the visibility of the contents (drawings) displayed on the operation panel 14 is improved. That is, by limiting the contents described in the drawings, it is possible to easily confirm the correctness of the surveyed position when displaying the survey points measured by the surveying machine 5.

The drawing display means 26 includes a drawing unit setting unit 26A, a display range setting unit 26B, and a display rotation angle setting unit 26C. The drawing display means 26 operates an operation panel on the read drawing based on the conditions set in these setting units. 14 is displayed.
The drawing unit setting unit 26A prompts the surveying operator to input distance units such as mm and m when creating the read drawing data, and sets the input distance unit as the distance unit of the drawing data. Specifically, an input field for inputting the distance unit of the drawing data is displayed on the operation panel 14 to prompt the surveying operator to input the distance unit. Thereby, the distance unit of the line element constituting the drawing displayed on the operation panel 14 is linked to the number of pixels representing the line element.

  The display range setting unit 26B prompts the surveying operator to input a range to be displayed on the operation panel 14 of the read drawing data, and displays the input drawing data of the range on the operation panel 14. Specifically, the input drawing is displayed on the operation panel 14, and it is urged to continuously tap two diagonal points assuming a virtual rectangular region surrounding the surveying range from the displayed drawing. Thereby, for example, when the read drawing data is a drawing showing the entire site, the selected range is enlarged and displayed so that the range to be surveyed is displayed largely on the operation panel 14. If the read drawing is a partial drawing, this processing may be omitted.

  The display rotation angle setting unit 26C prompts the surveying operator to input the drawing orientation (rotation angle) to the operation panel 14 when displaying the drawing data on the operation panel 14, and rotates the drawing at the input rotation angle. Are displayed on the operation panel 14. For example, the rotation angle is set so that the longitudinal direction of the drawing displayed on the operation panel 14 is displayed along the long side direction of the operation panel 14. Thereby, the range of the survey target in the drawing can be displayed largely on the operation panel 14.

  The machine point display means 28 includes a machine unit setting unit 28A and a machine point registration unit 28B, and operates based on the coordinate value of the machine point (hereinafter referred to as the machine point coordinate value) input from the surveying machine 5 side. The machine point is displayed on the drawing displayed on the panel 14. The machine point means a position where the surveying machine 5 is installed, and is displayed on the operation panel 14 by a predetermined icon such as Δ.

  The machine unit setting unit 28A prompts the surveying operator to input a distance unit such as mm or m of the machine point coordinate value or the survey point coordinate value input from the surveying machine 5, and the input distance unit is set to the machine point coordinate. Set as a distance unit for values and survey point coordinate values. Thereby, the distance unit input from the surveying machine 5 is unified to the distance unit of the drawing. The machine point registration unit 28B reads the machine point coordinate value input from the surveying machine 5 and registers it as a machine point.

The survey point display means 30 includes a survey point registration unit 30A and a coordinate conversion unit 30B, and is measured on the drawing displayed on the operation panel 14 based on the survey point coordinate values input from the surveying machine 5 side. Display the survey points. The survey point is displayed on the operation panel 14 by a predetermined icon such as ◯.
The survey point registration unit 30A prompts the survey operator to input a name corresponding to the survey point coordinate value input from the surveying machine 5, sets the input name as the survey point coordinate value, and registers it as a survey point. To do. Specifically, an input field for inputting a name is displayed on the operation panel 14 to prompt the surveying operator to input the name. Then, when the surveying operator inputs an arbitrary name in the input field, the input survey point coordinate value is registered as a survey point. The registered survey points are linked to the drawing and registered as observation information.

  The coordinate conversion unit 30B converts the survey point coordinate value input from the surveying machine 5 into a drawing coordinate value. The survey points whose coordinate values have been converted by the coordinate conversion unit 30B are displayed on the drawing displayed on the operation panel 14. The drawing acquired by the drawing acquisition means 24 is created based on the drawing coordinate system using CAD software. On the other hand, since the survey point coordinate value input from the surveying machine 5 is a survey coordinate system, it is different from the coordinate system of the drawing. For this reason, the coordinate conversion unit 30B converts the survey point coordinate values (surveying coordinate system) input from the surveying machine 5 into coordinate values in the drawing coordinate system. Thus, the survey point input from the surveying machine 5 is automatically converted into drawing coordinates, and the position can be displayed on the drawing displayed on the operation panel 14 simultaneously with the surveying. Therefore, the surveying operator can immediately confirm the correctness of the surveying and the suitability of the construction itself by visually recognizing the position of the surveying point displayed overlapping the displayed drawing.

  The observation information calculation display means 32 executes processing for providing observation information to the surveying operator based on the drawings and survey points displayed on the operation panel 14 after surveying. The observation information calculation display means 32 displays the observation information on the operation panel 14 in response to the surveying operator tapping a line segment, a survey point, a machine point, or the like of the drawing displayed on the operation panel 14 with a fingertip. For example, by specifying a line segment of the drawing, the dimension of the line segment is displayed superimposed on the drawing. Further, by tapping the survey point displayed on the operation panel 14 with a fingertip, the coordinate value of the survey point is displayed beside the survey point. In addition, by designating two survey points displayed on the operation panel 14, a distance between the two selected points is calculated, a line segment connecting the two survey points is drawn, and the calculated distance is calculated. indicate.

  The surveying machine 5 is a three-dimensional observation machine that controls surveying using light waves by a computer. The surveying machine 5 includes a lightwave distance meter, an angle meter, a collimation control unit, a surveying control unit, a calculation unit, and a communication unit (not shown). The optical distance meter is provided so that the irradiation direction of the distance measuring light (laser) can be changed up and down, left and right, irradiates the target on the measurement object with the laser, and the distance to the target based on the received reflected light Measure. The goniometer measures the horizontal and vertical angles of the optical axis of the laser emitted toward the target.

Based on the distance, horizontal angle, and vertical angle measured by the light wave distance meter and the angle meter after the surveying machine 5 is installed, for example, using a plurality of known points at the survey site by the backward intersection method. The machine point coordinate value is calculated. Further, the calculation means calculates the survey point coordinate value of the survey point based on the distance to the target (survey point), the horizontal angle, and the vertical angle measured by the light wave distance meter and the angle meter. The calculated survey point coordinate value is obtained by a survey coordinate system (orthogonal coordinate system). The survey coordinate system in this example is based on the position of the machine point of the surveying machine 5, the north-south is the X axis, the east-west is the Y axis, true north is the positive value of the X axis, and true east is the positive direction of the Y axis. Is set. Also, the vertical (height) is set as the Z axis. The calculated machine point coordinate values and survey point coordinate values are output to the communication means.
If the surveying machine 5 is equipped with a GPS receiver, the coordinate value obtained based on the position measured by the GPS receiver is output to the communication means as the machine point coordinate value.

  The collimation control means controls the direction of the light wave distance meter so as to automatically collimate the position of the target installed on the survey target at the construction site based on the survey command input from the survey position display device 4. . For example, when performing collimation surveying, the collimation control means starts from the initial position of the surveying machine 5 (both horizontal and vertical angles are zero degrees) based on the relative angle included in the input survey command. It automatically changes its direction and automatically collimates a target installed at a predetermined position on the outer surface of a building member such as a column or beam. Further, the collimation control means irradiates the laser toward the coordinate value input from the surveying position display device 4 when performing the pile driving surveying, and performs the surveying work while maintaining the state in which the target is irradiated with the laser. Control is performed so that the coordinate value desired to be obtained at the site can be obtained by moving the target by the person.

  The communication means enables communication with the surveying position display device 4, and inputs surveying commands from the surveying position display device 4 and outputs observation results such as machine point coordinate values and survey point coordinate values to the surveying position display device 4. To do.

Hereinafter, the flow of surveying work using the surveying position display device 4 will be described. In the following description, it is assumed that the processed data is stored in the server 3 in advance, and the surveying operation is performed as a radiation survey (coordinate survey).

As the target, a prism or a target seal is suitable, and a non-prism can be used when the measurement accuracy of an obstacle or the like is not required precisely.

  After the surveying machine 5 is arranged, for example, a machine point coordinate value at which the surveying machine 5 is installed is acquired by a backward intersection method using a reference point or a known point previously installed at the surveying site. The machine point coordinate value is transmitted to the survey position display device 4 via the wireless LAN router 7.
