[0021]
FIG. 2 is a schematic view of a measurement system according to an embodiment of the present invention (in this embodiment, claim 7). As shown in FIG. 2, the present embodiment uses TS2 as an observation device, and uses a radio device 3 as a first communication means for transmitting guidance data and a second communication means for transmitting observation data. That is, in the present embodiment, by connecting one of the PC 1 and the wireless device 3 with the cable 4 and connecting the other of the TS 2 and the wireless device 3 with the other cable 4, the guidance data is transmitted from the PC 1 to the TS 2, and the TS 2 to the PC 1 It is configured to be able to transmit observation data. Further, TS2 is configured to change the horizontal angle of the observation device according to the guidance data received from PC1 by providing a servo motor.

However, by providing PC1 on the TS2 side and connecting TS2 and PC1 with a cable, guidance data is transmitted from PC1 to TS2, and TS2 to PC1. It is good also as a structure which transmits observation data.
[0022]
In the present embodiment, measurement is performed by the following procedure using the measurement apparatus and measurement system configured as described above. FIG. 14 is a flowchart showing an example of the overall flow of the operation of the PC 1. In the flowchart of FIG. 14, sketching is performed first, and then, until all the measurements are completed (for example, menu buttons other than machine installation, backsight setting, guidance, and measurement are input to the PC 1) When observation data storage is repeated and all measurements are completed (for example, when menu buttons other than machine installation, backsight setting, guidance, and measurement are input to PC1), the measured shape is displayed at once, and then the sketch shape is displayed once. Shows the case of deformation.
[0023]
▲ 1 ▼ Sketch
A point staff and a TS staff (hereinafter also referred to simply as a staff) walk around the site, select an observation point, and sketch an approximate site shape on the PC 1. At this time, the person in charge creates a sketch while walking according to the observation point, or the person in charge creates a sketch while staying in a place where the entire site can be seen. Details of the sketch means will be described below.
[0024]
First, as shown in FIG. 4, the person in charge touches the point creation button 12 on the menu, and instructs the point creation by touching the approximate position of the observation point with the pen 11 on the screen of the PC 1. Further, the person in charge sets the TS2 installation point where the entire site or the place where the site can be maximized is touched, touches the point creation button 12 of the menu, and touches the approximate position on the screen of the TS installation point with the pen 11. Create a point. Similarly, the point of the backsight point for determining the reference direction of the horizontal angle 0 is created. The TS installation point and the backsight point may be at the same position as any observation point. Note that the TS installation point and the backsight point may be set before guidance, without being set at the time of sketching. The PC 1 displays a point mark (for example, ●) at the touched position. Further, the PC 1 generates point numbers in the order of point creation, displays them on the screen, and stores them in association with coordinate values on the screen. Furthermore, the person in charge inputs a point name for each observation point. The PC 1 stores the point name in association with the point number.
[0025]
Next, as shown in FIG. 5, the person in charge touches the connection button 13 on the menu and touches two points to instruct connection. The PC 1 displays the connection and stores connection information such as which point is connected. Note that the PC 1 determines that the point has been selected even if the vicinity of a certain point mark is touched. That is, if the PC 1 is touched in an area having a predetermined radius centered on each point mark, the PC 1 determines that the point has been selected.
[0026]
Further, the person in charge inputs the field attribute using a line segment / free curve or the like as shown in FIG. The PC 1 stores the position, shape, etc. of the input attribute and displays it on the screen as input.
[0027]
An example of a flowchart of a program for causing the PC 1 to function as the sketch means is shown in FIG. If the menu button input to the PC 1 is a menu button for sketching such as point creation / connection, the program determines that the input point etc. is a sketch, and responds to the menu button for the input point etc. Process and display. For example, if a menu button for point creation is input, as shown in the flowchart of FIG. 20, a point number is generated for the next input point, and the coordinates on the screen of the input point corresponding to the point number are generated. The point creation process for storing the value and displaying the point mark and the point number on the screen is performed until the next menu button is input.
[0028]
After creating the sketch, the person in charge of the point stands a mirror in the order of measurement based on the sketch. In addition, the point staff corrects the sketch when the necessary points are added. At this time, the PC 1 adds a point number and stores the coordinate value of the point on the screen.
[0029]
By this sketching means, the observation object is plotted before observation, so that the observation can be performed smoothly based on this. For example, by setting up a mirror based on this sketch, it is possible to avoid setting up the mirror by mistaken observation points. In addition, when the observation data is later transferred to a computer in the company and connected on a graphic, the connection information stored in the PC 1 can be used, so that no connection mistakes are eliminated.
[0030]
(2) Guidance
The person in charge directs guidance after setting up a mirror at the point to be observed. Details of the guiding means will be described below.
[0031]
First, prior to guidance, the person in charge of TS installs TS2 at the installation point and adjusts the direction of TS2 so as to face the backsight point. Then, as shown in FIG. 6, the person in charge touches the machine installation button 14 in the menu and also touches the mark of the TS installation point (point number 6 in FIG. 6) on the screen of the PC 1 to display the PC 1 Teach the installation points of TS2. In addition, as shown in FIG. 7, the person in charge touches the backsight setting button 15 on the menu and touches the backsight point mark (point number 5 in FIG. 7) to connect the backsight point to the PC 1. teach. The PC 1 stores the direction from the TS installation point toward the backsight point as a reference direction with a horizontal angle of zero. Next, when the person in charge of the point touches the guide button 16 on the menu as shown in FIG. 8 and touches the mark of the point to be observed (point number 3 in FIG. 8), the PC 1 observes. The swing angle of TS2 from the reference direction is calculated based on the coordinate value on the screen of the point to be transmitted, and this is transmitted as guidance data to TS2 through radio 3. TS2 that has received the guidance data drives the servo motor to face the mirror. In the embodiment in which PC1 is provided on the TS2 side and connected by a cable, PC1 transmits guidance data to TS2 through the cable.
[0032]
An example of a flowchart of a program for causing the PC 1 to function as the guiding means is shown in FIG. This program calculates the swing angle from the reference direction as guidance data based on the coordinate value on the screen of the observation point inputted next when the menu button input to PC1 is guidance, If it is set to the machine installation or rear view setting, it is determined that the reference direction is set, and then the reference direction is set based on the input coordinate value of the TS2 installation point or rear view point on the screen. . The PC 1 receives the input of the next menu button.
Since this guide means guides TS2 approximately in the direction of the mirror, collimation of the mirror is facilitated.
[0033]
(3) Transmission and storage of observation data
After confirming the points to be measured with the point staff by the point number / point name, etc., the TS staff manually fine-tunes the horizontal angle and adjusts the vertical angle so that TS2 collimates the mirror correctly. And observe the point. In the embodiment that does not include the above-described guiding means, for example, the horizontal angle and the vertical angle are manually adjusted, and the point is observed.
[0034]
After the observation, when the person in charge touches the measurement button 17 (see FIG. 9) on the menu, the PC 1 uses the wireless device 3 to request the TS 2 to transmit observation data, and the TS 2 measures the horizontal angle, vertical angle, and light wave distance. Observation data such as the measured distance is transmitted to the PC 1 using the wireless device 3.
[0035]
In the embodiment in which the observation data is not transmitted, for example, when the TS person in charge has PC1, the TS person in charge inputs observation data directly to PC1, and when the point person in charge has PC1, the TS person in charge A person inputs observation data to the PC 1 by means such as transmitting the observation result to the point person by voice using a wireless device or the like.
[0036]
The PC 1 stores the received observation data in association with the point numbers of the points on the sketch, and displays them on the screen as needed as shown in FIG.
[0037]
An example of a flowchart of a program for causing the PC 1 to function as the observation data storage means is shown in FIG. If the menu button input to the PC 1 is a measurement, this program transmits a signal requesting transmission of observation data to TS 2 and stores the observation data received from TS 2 in association with the point number. If the observation data needs to be displayed, the PC 1 displays the observation data on the screen and receives the input of the next menu button.
[0038]
This observation data storage means eliminates input errors when it is later transferred to a company computer. Further, since the points and the observation data are automatically stored in association with each other, there is no recording error. Further, the person in charge of the point has the PC 1, and while confirming the attribute of the site on the spot, the observation data is displayed on the screen and compared with the attribute, so that an observation mistake can be found intuitively.
[0039]
▲ 4 ▼ Measured shape display
There are two types of measured shape display means for displaying the measured shape on the screen of the PC 1 in association with the sketch shape: means for displaying at once after all measurements are completed, and means for sequentially displaying each measurement.
[0040]
In the means for displaying all at once after the completion of all measurements, the person in charge touches the display button of the menu when all the observation data is prepared, and the PC 1 displays the measured shape in association with the sketch shape. An example of this measured shape display means is shown below.
[0041]
First, the PC 1 selects, for example, a point closest to the screen origin on the sketch as a point at which the sketch shape and the actually measured shape are overlapped, and after making the coordinate value by the sketch of the point and the coordinate value by the actual measurement identical, Calculate the coordinate values of other points. And each point is displayed on a screen using the coordinate value by actual measurement. At this time, for example, the PC 1 calculates the scale based on the ratio of the distance on the screen from the TS installation point to the first observation point and the actually measured distance. Then, each point is connected with, for example, a broken line using the connection information, and the actually measured shape is displayed. This state is shown in FIGS. FIG. 10A shows the actual site shape, and FIG. 10B shows the sketch shape on the screen of the PC 1. The PC 1 considers that the point 1 within a predetermined area of the screen origin coincides with the screen origin, selects it as a point to be overlapped, and sets the coordinate value of the point 1 in the actually measured shape as X = 0.00, Y = After setting to 0.00, other points are coordinated based on the observation data as shown in FIG. Then, as shown in FIG. 11B, the actually measured shape and the sketch shape are displayed in an overlapping manner.
[0042]
FIG. 18 shows an example of a flowchart of a program for causing the PC 1 to function as the actually measured shape display means. If the menu button input to the PC 1 is displayed, this program calculates the coordinate value by actual measurement of each point as described above, and displays the actual measurement shape.
[0043]
Further, in the means for sequentially displaying each measurement, the PC 1 automatically displays and connects points by actual measurement every measurement, that is, every time observation data is obtained. An example of this measured shape display means is shown below.
[0044]
First, the PC 1 selects, for example, the first observation point as a point at which the sketch shape and the actual measurement shape are overlapped, and displays the first observation point by making the coordinate value of the sketch of the point and the coordinate value of the actual measurement identical. Then, each time the observation data is obtained, the PC 1 calculates a coordinate value obtained by actually measuring the point, and displays the point on the screen using the coordinate value. At this time, for example, the PC 1 calculates the scale based on the ratio of the distance on the screen from the TS installation point to the first observation point and the actually measured distance. The PC 1 refers to the connection information, and if the displayed point is connected to any of the previously displayed points, the PC 1 connects these points with a broken line, for example. Similarly, the PC 1 sequentially displays the measured shape every time observation data is obtained.
[0045]
The person in charge compares the actually measured shape with the sketch, and if there is a mistake, remeasures and displays the actually measured shape again.
[0046]
With this measured shape display means, mistakes in observation data can be judged intuitively, and it can be remeasured and corrected immediately on site.
[0047]
(5) Deformation
Furthermore, the deformation means for deforming the measured shape according to the sketch shape also corresponds to the measured shape display means, that is, a means for deforming at one time after the completion of all measurements and a means for successively deforming each measurement. There is.
[0048]
In the means for deforming at one time after completion of all measurements, when the person in charge touches the deformation button on the menu, the sketch shape is deformed so as to match the actually measured shape. This is shown in FIGS. That is, the PC 1 moves the solid line intersection to the position of the broken line intersection as shown by the arrow in FIG. 12B for the portion where the local shape and the sketch shape are shifted as shown in the circle of FIG. At the same time, the connection is expanded and contracted to deform the sketch shape. As a result, the sketch shape as shown in FIG. 13A is replaced with the actually measured shape as shown in FIG.
[0049]
FIG. 19 shows an example of a flowchart of a program that causes the PC 1 to function as the deformation means. If the menu button input to the PC 1 is deformed, this program converts the coordinate value and connection of each point to match the measured shape, and displays the deformed shape.
[0050]
In addition, with the means of sequentially deforming for each measurement, the PC 1 displays the actual measurement shape for each measurement, and automatically moves the points on the sketch to the points indicated by the coordinate values by the actual measurement for each measurement. And expand and contract the connection.
[0051]
With this deformation means, the observation result can be seen in real, and an observation mistake can be found at the observation stage in the field. In addition, after completing the drawing, comparing the deformed shape with the drawing will help to discover mistakes in the observation results.
[0052]
▲ 6 ▼ Drawing completion
After observation, the observation data recorded at the site is transferred from PC1 to a computer in the company, etc., and connected on the graphic. Also, check whether the attribute of the site is expressed in a predetermined format. The CAD function is used for correction, and the drawing is completed using an automatic plotter or the like.
[0053]
At this time, according to the present invention, there is no occurrence of an input error to the computer due to a dirty memo character, an ambiguous expression, or the like. Absent.
[0054]
In this embodiment, the total station is used as the observation device. However, the observation device is not limited to the total station as long as the observation data can be obtained digitally. The present invention can also be applied to observation of a three-dimensional shape, for example, by using a level (electronic level) as an observation device.
[0055]
