  The present invention relates to an automatic surveying system and an automatic surveying method.

  2. Description of the Related Art Conventionally, there is an automatic surveying system technology based on a combination of a surveying instrument and a terminal device or a GPS (Global Positioning System) system. For example, Japanese Patent Laying-Open No. 2002-174518 (Patent Document 1) discloses an automatic surveying system including an automatic tracking type surveying device and a portable terminal device. The automatic tracking type surveying device includes automatic tracking means for a target to be measured, target position measuring means, data transmitting / receiving means, and control means. The portable terminal device includes a screen display unit, a screen display data creation unit, another data transmission / reception unit for transmitting / receiving data to / from the data transmission / reception unit, and another control unit. It comprises an automatic tracking type surveying device and data storage means provided in at least one of the portable terminal devices. As a result, the automatic tracking type surveying device automatically tracks and measures the position of the target to be measured, so that the surveying technician moves the planned measurement point within the area to be surveyed while holding the target. It is stated that a surveying technician can independently perform surveying of a wide area, and that the measured data is automatically recorded by a data storage means, thereby eliminating artificial surveying errors. Further, it is stated that since both the automatic tracking type surveying device and the portable terminal device have the control means, the surveying work can be continued even when one of the control means is out of order.

  Japanese Patent Laying-Open No. 2006-234776 (Patent Document 2) discloses an automatic surveying system including a coordinate measuring unit, a recording unit, a coordinate determining unit, a displacement calculating unit, and a coordinate correcting unit. The coordinate measuring means measures coordinates of a target to be measured and fixed points arranged at two different places from the target. The recording means records the coordinates of the fixed point measured by the coordinate measuring means as initial coordinates. The coordinate determining means determines whether or not the coordinates of the fixed point measured again by the coordinate measuring means match the initial coordinates. The displacement calculating means calculates the displacement of the fixed point when the coordinates of the fixed point do not match the initial coordinates. The coordinate correcting means calculates a correction amount based on the displacement of the fixed point, and corrects the coordinates of the target measured by the coordinate measuring means. This makes it possible to correct the measurement result of the target based on the initial coordinates of the fixed point, thereby reducing the error of the measurement result due to the displacement of the automatic measuring device.

The portable relay device is electrically connected to a portable antenna device for receiving a radio wave from a GPS satellite, and transmits a GPS signal received by the portable antenna device as a relay signal on a carrier wave. The fixed receiving device is installed at a fixed station having known coordinates on the ground, and receives a radio wave from a GPS satellite and a relay signal from a relay device. The coordinate calculating means calculates three-dimensional coordinates of the portable antenna device from the received GPS signal from the fixed antenna at the fixed station, the received GPS signal from the portable antenna device received via the relay device, and the known coordinates. The transmitter sends the calculated three-dimensional coordinates from the fixed station as coordinate signals. The portable display means has a portable receiver for receiving the coordinate signal, and displays the coordinate signal received by the receiver. Then, by positioning the portable antenna device on the ground surface measurement point distant from the fixed station while being connected to the portable relay device, the three-dimensional coordinates of the measurement point are measured in real time and displayed on the portable display means. This makes it possible to reduce the size and weight of the device that moves to the measurement point in real-time surveying, so that the labor of the worker in GPS surveying can be reduced, the work efficiency in GPS surveying can be improved, and the target position and measurement point can be measured. By displaying the three-dimensional coordinates relative to each other, the surveying device can be efficiently moved to a target position on a design drawing and accurately positioned.

  Japanese Patent Laying-Open No. 10-267656 (Patent Document 4) discloses a surveying system including a centralized processing device and a plurality of surveying devices. The centralized processing device includes a survey plan management unit, a data acquisition unit, a survey data analysis unit, an analysis result determination unit, and a communication connection unit. The survey plan management means stores a survey plan such as an installation position of a survey instrument and a survey method. The data capturing unit captures survey data of each surveying instrument via the communication unit. The survey data analysis means analyzes the survey using the survey data taken into the data taking means. The analysis result determination means determines whether the survey error is within an allowable range by combining the analysis result with the survey plan. The communication connection means connects the data acquisition means and the survey data analysis means to the communication means. Each surveying instrument has transmission / reception control means for sending survey data to the central processing unit by communication means. Thus, the data measured by each surveying instrument can be transmitted to the central processing unit by the communication means, and the data collected by each surveying instrument can be analyzed and analyzed by the central processing unit. According to the report, it is possible to judge the suitability of the survey result even in a state, etc., and to start the re-measurement promptly when the re-measurement is necessary.

  Japanese Patent Laying-Open No. 2000-18945 (Patent Document 5) discloses a surveying device including a global positioning system and a direction sensor. The global positioning system receives a radio wave from a positioning satellite via a positioning antenna, and calculates the distance between the current position where the positioning antenna is located and the target point based on the radio wave, information on the reference point, and information on the target point. You can get the bearing. The azimuth sensor is provided with a display that indicates a predetermined direction, and can notify the azimuth that the display takes with respect to the reference azimuth. The direction from the current position to the target position can be indicated by matching the direction obtained by the direction sensor with the direction obtained by the global positioning system. According to the document, it can be easily handled and can easily reach the target point in a short time.

  Japanese Unexamined Patent Application Publication No. 2002-6026 (Patent Document 6) discloses means for setting an unknown target position, GPS observation information sent from a fixed station at a known position, and reception by a portable mobile station. Means for calculating the current position of the mobile station based on the GPS observation information, and display control means for graphically displaying the relationship between the set target position and the calculated current position of the mobile station on a portable display device. A target position guidance system comprising the same is disclosed. Thus, the user carrying the display device can be guided to the target position in accordance with the guidance screen by simply instructing the calculated survey setting point, and can easily move the GPS mobile station to the target position. Therefore, it is possible to easily perform three-dimensional measurement and search for a buried object whose position coordinates are known without the need to secure a line of sight, and to confirm one's own position on the screen. It is said that work efficiency can be dramatically improved because work can be performed while doing so.

  Japanese Patent Laying-Open No. 2002-365054 (Patent Document 7) discloses a surveying instrument network system in which a plurality of surveying instruments and an information processing instrument are connected. Each device has an inquiry means for inquiring necessary information to other equipment connected to the surveying equipment network system, and a response means for responding to an inquiry from other equipment connected to the surveying equipment network system. doing. As a result, necessary information can be distributed and stored or processed in each surveying device or information processing device. Therefore, even if some devices are out of order, information necessary for surveying can be transmitted from other devices. It is possible to perform the surveying work smoothly without using a high-speed, large-capacity, expensive information processing device or communication means even if the number of surveying instruments increases, because the number of surveying instruments increases. And

  In conventional surveying, it is normal to perform the surveying by one pair. One is a surveying engineer who operates a surveying instrument, and the other is a surveying assistant who moves a target to a surveying position. At the time of surveying, the surveying assistant is far away from the surveying engineer, so it is difficult for the surveying engineer to grasp the surveying position, while the surveying assistant is difficult to grasp the survey result.

  In addition, a surveying technician stores survey results in a server on the network, so that a third party such as a supervisor who can access the server checks the survey results and determines whether the survey results are appropriate. ing. Here, there is a time lag between the surveying technicians' surveying time and the third party's confirmation time, so when a third party wants to request a re-survey from the survey results, the surveying technicians have already The situation of returning home may occur. In such a case, re-measurement of the survey or the like occurs, so that quick sharing of the survey result is required.

  In the technique described in Patent Document 1, although an automatic tracking type surveying device (automatic tracking type total station) plays the role of a surveying engineer, it is said that a surveying engineer or a surveying assistant who is a survey assistant can perform the survey independently. It is necessary for the surveyor to perform the instrument point measurement (such as back intersection) of the automatic tracking type surveying apparatus by the side of the automatic tracking type surveying apparatus. In the technique described in Patent Document 2, although a fixed point of the automatic surveying device of the automatic surveying system is corrected, surveying engineers are required to set initial coordinates and measure target coordinates. Therefore, the techniques described in Patent Literatures 1 and 2 have a problem that it takes time and effort to measure the instrument point.

  In the technology described in Patent Document 3, it is necessary to develop a portable antenna device, and only the three-dimensional coordinates of the portable antenna device are calculated using the received GPS signals, so that the measurement accuracy is limited. According to the technique described in Patent Document 4, although the survey data of each surveying instrument can be collected in the central processing unit, it is possible to solve the elimination of the time lag between the survey time of the survey engineers and the confirmation time of the third party. Not something.

  In the technology described in Patent Literature 5, it is necessary to develop a display that can communicate with the global positioning system, and it is only necessary to calculate the position of the display using the global positioning system (GPS). Measurement accuracy is limited. Similarly, in the technology described in Patent Document 6, it is necessary to develop a mobile station having a GPS antenna, and since the position of the mobile station is calculated using GPS, measurement accuracy is limited. In the technique described in Patent Document 7, a surveying device is inquired to other devices connected to the network, and a response is received. However, this does not easily lead to the elimination of the labor and time of the surveying performed by one pair.

  Therefore, the present invention has been made to solve the above-mentioned problems, and an automatic surveying method that allows a single surveyor to easily and efficiently perform the process from actual instrument point calculation to surveying. It is an object to provide a system and an automatic surveying method.

  As a result of intensive studies, the inventor has completed a new automatic surveying system and a new automatic surveying method according to the present invention. That is, the automatic surveying system according to the present invention is an automatic surveying system that connects a surveyor terminal device that controls a surveyor, a surveyor terminal device carried by a surveyor, and a server via a network so that they can communicate with each other. A surveying system, a reference point display control unit, an inclination angle control unit, a temporary instrument point control unit, a search condition control unit, a reference point selection control unit, an actual instrument point control unit, a survey control unit, , Is provided.

  The reference point display control unit causes the surveyor terminal device to display a plurality of reference points having XY coordinate values registered in advance in the XY coordinate system of the drawing of the survey site where the surveying instrument is installed. The tilt angle control unit determines whether the XY tilt angle of the surveying instrument is within a predetermined XY determination value. When the XY tilt angle is within the XY determination value, the temporary instrument point control unit acquires the XY coordinate values of the temporary instrument point of the surveying instrument in the XY coordinate system of the drawing of the survey site. The search condition control unit, upon receiving an input of a search range from a surveyor, based on the XY coordinate value of the temporary instrument point, the XY coordinate value of the reference point, and the search range, and based on the search range, The relative distance between the reference point and the search angle of the surveying instrument swinging around the reference point as viewed from the surveying instrument are calculated for each reference point, and the relative distance is calculated for each reference point. And a reference point list that associates the search angle with the search angle. The reference point selection control unit causes the surveyor terminal device to display the reference points in the reference point list in a descending order of the relative distance of the reference points. The actual instrument point control unit receives, from the surveyor, two reference points among the reference points in the reference point list as two selected reference points, and then, for each of the two selected reference points at the survey site, Then, the surveying instrument is automatically collimated using the temporary direction angle of the surveying instrument and the search angle of the reference point, and the direction angle of the target of the selected reference point viewed from the surveying instrument, The XY coordinate value of the actual instrument point of the surveying instrument is calculated by measuring the distance between the instrument and the target of the selected reference point. The surveying control unit, when a target is set at a predetermined observation point in the survey site by the surveyor and receives the XY coordinate value of the observation point in the XY coordinate system of the drawing of the survey site from the surveyor, the actual instrument. The surveying instrument is rotated to the target of the observation point based on the XY coordinate value of the point and the XY coordinate value of the observation point, and the surveying instrument is caused to measure the XY coordinate value of the target of the observation point.

  An automatic surveying method according to the present invention is directed to an automatic surveying system in which a surveyor terminal device that controls a surveyor, a surveyor terminal device carried by a surveyor, and a server are communicably connected via a network. Automatic surveying method, comprising: a reference point display control step, a tilt angle control step, a temporary instrument point control step, a search condition control step, a reference point selection control step, an actual instrument point control step, and a survey control. And step. Each step of the automatic surveying method corresponds to each section of the automatic surveying system.

  Next, a configuration and an execution procedure according to the embodiment of the present invention will be described with reference to FIGS.

<Instrument point measurement>
FIG. 3 is a flowchart showing an execution procedure of the instrument point measurement according to the embodiment of the present invention. First, the surveyor carrying the surveyor terminal device 12 brings the surveyor 10 and the surveyor terminal device 11 to the surveying site, and as shown in FIG. 4A, moves the surveying device to a predetermined location on the surveying site. 10 and a terminal device 11 for a surveying instrument are installed. A plurality of targets 2a, 2b, 2c,... (Prisms, etc.) are installed in advance at the survey site where the surveying instrument 10 is installed, corresponding to each reference point of the survey site.

  When the surveyor activates the surveyor terminal device 12, the output unit (for example, a touch panel) of the surveyor terminal device 12 displays the top screen 400 as shown in FIG. 4B. On the top screen 400, a file key 401, a tilt display key 402, a backward association key 403, a general survey key 404, a stakeout survey key 405, and a setting key 406 are provided.

  The file key 401 is a key for reading a file. The tilt display key 402 is a key for displaying the inclination angles of the surveying instrument 10 in the X-axis direction and the Y-axis direction. Here, the X-axis direction is the front-back direction of the survey coordinate system (Japan Geodetic System), the Y-axis direction is the left-right direction of the survey coordinate system, and the Z-axis direction is the vertical direction (height) of the survey coordinate system. Direction. The X-axis direction and the Y-axis direction constitute a horizontal direction, and the Z-axis direction constitutes a vertical direction. The back intersection key 403 is a key for calculating the coordinates of the surveying instrument 10 (instrument point). The general survey key 404 is a key for surveying a predetermined observation point (selected point). The stakeout survey key 405 is a key for measuring a predetermined stakeout point. The setting key 406 is a key for performing various settings.

  First, when the surveyor selects the file key 401 to call a drawing indicating the reference point of the survey site, the input unit (for example, a touch panel) of the surveyor terminal device 12 receives the selection of the file key 401. Then, the reference point display control unit 201 of the surveyor terminal device 12 receives a key input from the surveyor, and registers the XY coordinates registered in advance in the XY coordinate system of the drawing of the surveying site where the surveyor 10 is installed. A plurality of reference points having values are displayed on the surveyor terminal device 12 (FIG. 3: S101).

  There is no particular limitation on the method by which the reference point display control unit 201 causes the surveyor terminal device 12 to display a plurality of reference points. For example, the reference point display control unit 201 first displays a drawing acquisition screen for selecting drawing data of the survey site and data of the reference point of the survey site on the touch panel.

  As shown in FIG. 5A, on the drawing acquisition screen 500, a cooperation key 501 and a connection status 502 are displayed. The cooperation key 501 is a key for using a file box (database) on the network 15. The connection status 502 indicates a network connection status. In the connection status 502, "unlinked" is displayed because the terminal device for surveyors 12 is not yet connected to the file box.

  Here, when the surveyor uses the file box on the network 15 and selects the link key 501, the reference point display control unit 201 accepts the selection of the link key 501 and accesses the file box on the network 15. Display the login screen for the file box. When the surveyor inputs an account (for example, an e-mail address) and a password on the login screen and selects a login key, the reference point display control unit 201 accepts the account and the password, and the file box is authenticated.

  Then, when the authentication is successful, as shown in FIG. 5A, “cooperated” is displayed in the connection status 502, and account information (for example, country, name, mail address, etc.) is displayed. Thus, the surveyor can use the file box on the network 15.

  Also, as shown in FIG. 5B, a CAD file read key 503, a data file read key 504, a read status 505, a CAD file save key 506, and a data file save key 507 are displayed on the drawing acquisition screen 500. Is done. A CAD file read key 503 is a key for reading drawing data (CAD file) of the survey site. A data file read key 504 is a key for reading data (data file) of a reference point corresponding to a target installed at a predetermined position on the survey site. The read status 505 indicates the read status of the CAD file and the data file. Nothing is displayed in the read status 505 because the CAD file and the data file have not been read yet. The CAD file storage key 506 is a key for storing the read CAD file in the surveyor's terminal device 12, and the data file storage key 507 is for storing the read data file in the surveyor's terminal device 12. Is the key.

  When the surveyor selects the CAD file read key 503, the reference point display control unit 201 displays the CAD file existing in the file box in a selectable manner. When a CAD file (for example, “A-1”) corresponding to the site is selected, the reference point display control unit 201 reads the selected CAD file (“A-1”). Similarly, when the surveyor selects the data file read key 504, the reference point display control unit 201 displays the data file existing in the file box in a selectable manner. When a data file (for example, “a-1”) corresponding to the survey site is selected, the reference point display control unit 201 reads the selected data file (“a-1”).

  Here, the CAD file and the data file are set to the same or similar file names related to the same survey site so that the surveyor can recognize the CAD file and the data file of the same survey site. It is preferable to keep it.

  When the reading of the CAD file and the data file is completed, the selected CAD file (“A-1”) and the data file (“a-1”) are displayed in the reading status 505 as shown in FIG. 5B. Is done. Thus, the surveyor can confirm the reading status of the CAD file and the data file.

  Then, when the surveyor selects the CAD file storage key 506, the reference point display control unit 201 stores the read CAD file (“A-1”) in the storage unit of the surveyor terminal device 12. When the surveyor selects the data file storage key 507, the reference point display control unit 201 stores the read data file (“a-1”) in the storage unit of the surveyor terminal device 12. Thus, the CAD file and the data file can be read by the surveyor's terminal device 12, and the surveyor can edit and add the CAD file and the data file using the surveyor's terminal device 12.

  In the above description, the surveyor uses the file box on the network 15 to read and save the CAD file and the data file of the survey site, but as another method, the storage section of the surveyor terminal device 12 is used. In the case where the CAD file and the data file are stored in advance, the surveyor may read the CAD file and the data file by selecting the CAD file and the data file in the surveyor's terminal device 12. .

  When the reading of the CAD file and the data file is completed, the reference point display control unit 201 displays a plurality of reference points on the drawing of the survey site based on the CAD file and the data file. Specifically, the reference point display control unit 201 expands the stored CAD file. The CAD file is basically a two-dimensional drawing of the survey site drawn in the XY coordinate system of the survey coordinate system, but the three-dimensional drawing of the survey site drawn in the XYZ coordinate system into which the Z value of the survey coordinate system is input. A three-dimensional drawing may be used. Next, when the reference point display control unit 201 refers to the stored data file, as shown in FIG. 6A, the data file 600 includes a point type 601 (for example, “reference point 1”) and a point name 602. (For example, “KK-1”), coordinates 603 (for example, XY coordinate values or XYZ coordinate values) in the survey coordinate system, and target information 604 (for example, target type, prism constant, (Prism size) are stored in association with each other. In the data file 600, a surveyor, a supervisor, and the like are created in advance according to the survey site, and reference points and their coordinates (XY coordinate values or XYZ coordinate values) are registered in advance.

  The reference point display control unit 201 acquires the coordinates 603 of the reference point (“reference point 1”) from the point types 601 of the data file 600, and stores the XY coordinate values of the acquired coordinates 603 of the reference point in the CAD file. 6B, the reference point 606a is displayed on the drawing 605 of the survey site, as shown in FIG. 6B. The reference point display control unit 201 plots the XY coordinate values of the coordinates 603 of the reference points on the XY coordinate system of the drawing 605 of the survey site for all the reference points stored in the point type 601 of the data file 600. Thus, all the reference points are displayed. Thus, the surveyor can grasp at a glance the position of the reference point 606 around the installation position of the surveying instrument 10 at the survey site.

  Further, the reference point display control unit 201 displays the point name 602a (“KK-1”) associated with the coordinates 603 of the displayed reference point 606a in the vicinity of the reference point 606a, so that the drawing 605 of the survey site is displayed. The upper reference point 606a can be identified. The reference point display control unit 201 displays the point names 602 near the reference points for all the reference points plotted on the XY coordinate system of the drawing 605 of the survey site, so that the surveyor can You can see at a glance what name the reference point is.

  When a plurality of reference points are displayed on the drawing of the survey site, the surveyor selects the tilt display key 402 next. Then, the input unit of the surveyor's terminal device 12 receives the selection of the tilt display key 402, and the inclination angle control unit 202 of the surveyor's terminal device 12 transmits the XY inclination angle of the surveying instrument 10 (X inclination in the X-axis direction). A horizontal tilt angle composed of the angle and the Y tilt angle in the Y-axis direction) is acquired (FIG. 3: S102).

  Specifically, the inclination angle control unit 202 communicates with the surveying device terminal device 11 via the network 15 and acquires the XY inclination angle of the surveying instrument 10 from the surveying device terminal device 11.

  When acquiring the XY inclination angle of the surveying instrument 10 from the surveying instrument terminal device 11, the inclination angle control unit 202 determines whether the acquired XY inclination angle is within a predetermined XY determination value for judging whether the surveying instrument 10 is horizontal. Is determined (FIG. 3: S103). The XY determination value includes an X determination value in the X-axis direction and a Y determination value in the Y-axis direction. The X tilt angle is determined by the X determination value, and the Y tilt angle is determined by the Y determination value. Note that the XY determination value is appropriately set by a surveyor, a manager, or the like.

  As a result of the determination, when the XY inclination angle is within the XY determination value (FIG. 3: S103 YES), in other words, when the X inclination angle is within the X determination value and the Y inclination angle is within the Y determination value, The tilt angle control unit 202 determines that the level of the surveying instrument 10 is normal, permits selection of all the keys of the back intersection key 403, the general surveying key 404, and the stakeout surveying key 405, and displays the tilt display screen. indicate.

  As shown in FIG. 7A, on the tilt display screen 700, an XY inclination angle 701 of the surveying instrument 10, a bubble image 702 imitating a bubble of a horizontal unit corresponding to the XY inclination angle, and a determination corresponding to the XY determination value. A line 703 is displayed. In this case, the bubble image 702 on the tilt display screen 700 is displayed inside the determination line 703. Thereby, the surveyor can confirm that the surveying instrument 10 is horizontal.

  On the other hand, as a result of the determination, when the XY inclination angle exceeds the XY determination value (FIG. 3: S103NO), in other words, when the X inclination angle exceeds the X determination value, or when the Y inclination angle exceeds the Y determination value. In this case, the inclination angle control unit 202 determines that the level of the surveying instrument 10 is abnormal (tilt over), and selects all the keys of the backward resection key 403, the general surveying key 404, and the stakeout surveying key 405. The transmission is not permitted and the transmission of the surveying instruction to the surveying instrument 10 is prohibited (lock processing is performed) (FIG. 3: S104).

  In this case, since the surveying instrument 10 installed at the surveying site is not horizontal, there is a high possibility that the accuracy of the surveying will be poor in the subsequent surveying. To prevent the surveyor from performing surveying under wrong conditions. In particular, when performed by one surveyor, such a determination process is extremely effective as a preliminary check. 7A, the tilt angle control unit 202 displays characters on the tilt display screen 700 in red, displays an error 704 on the tilt display screen 700, An error may be notified to the device 14.

  Here, in order to release the lock processing, the process returns to S102, and the surveyor manually levels the leveling table provided below the surveying instrument 10. In the case where the leveling platform is an automatic leveling platform capable of automatic leveling, the surveyor causes the automatic leveling platform to perform automatic adjustment via the surveyor terminal device 12. Then, when the surveyor selects the tilt display key 402 again, the tilt angle control unit 202 acquires the XY tilt angle of the surveying instrument 10 (FIG. 3: S102), and determines the XY tilt angle by the XY determination value. (FIG. 3: S103), the XY tilt angle falls within the XY determination value (FIG. 3: S103 YES). By doing so, the inclination angle control unit 202 permits selection of all of the rear intersection key 403, the general survey key 404, and the stakeout survey key 405.

  Now, when the surveyor selects the rear resection key 403 in a state where the level of the surveying instrument 10 is normal, the input unit of the surveyor terminal device 12 accepts the selection of the rear resection key 403, and The temporary instrument point control unit 203 of the device 12 acquires the XY coordinate values of the temporary instrument point of the surveying instrument 10 in the XY coordinate system of the drawing of the survey site (FIG. 3: S105).

  The method by which the temporary instrument point control unit 203 acquires the XY coordinate values of the temporary instrument point is not particularly limited. For example, the temporary instrument point control unit 203 displays a backward resection setting screen. As shown in FIG. 7B, the back resection setting screen 705 includes an instrument registration coordinate key 706, a GPS coordinate key 707, and coordinates 708 (XYZ coordinate values) of the temporary instrument point with respect to the temporary instrument point (estimated instrument point). ) Is displayed. The instrument registration coordinate key 706 is a key for acquiring XYZ coordinate values of instrument points registered in the surveying instrument terminal device 11 of the surveying instrument 10. The GPS coordinate key 707 is a key for acquiring the XY coordinate values of the temporary instrument point using the GPS function of the surveyor's terminal device 12. Note that nothing is displayed on the coordinates of the temporary instrument point 708 because the coordinates of the temporary instrument point have not yet been acquired.

  Here, when the installation location (XY coordinate value or XYZ coordinate value) of the surveying instrument 10 at the surveying site is registered in the surveying instrument terminal device 11 or the surveyor terminal device 12 in advance, the surveyor can use the instrument. When the registered coordinate key 706 is selected, the temporary instrument point control unit 203 acquires the installation location of the surveying instrument 10 from the surveying instrument terminal device 11 or the surveyor terminal device 12 as the XY coordinate values of the temporary instrument point.

  On the other hand, when the installation location of the surveying instrument 10 at the survey site has not been registered yet, the surveyor approaches the vicinity of the surveying instrument 10 by carrying the surveyor's terminal device 12, and the surveyor's terminal device 12 When the GPS coordinate key 707 is selected in a state in which the terminal is located near the surveying instrument 10, the temporary instrument point control unit 203 causes the GPS coordinate values (longitude, latitude) detected based on the GPS function of the surveyor terminal device 12. Is recognized as the XY coordinate value of the current position of the surveyor's terminal device 12, and this XY coordinate value is obtained as the XY coordinate value of the temporary instrument point. That is, since the surveyor's terminal device 12 is located near the surveying instrument 10, the temporary instrument point control unit 203 converts the XY coordinate values of the current position of the surveyor's terminal device 12 in the survey coordinate system into the survey coordinate system. The XY coordinate values of the temporary instrument points of the surveying instrument 10 are obtained and acquired. Thereby, the trouble of inputting the XY coordinate values of the temporary instrument point by the surveyor can be omitted.

  Here, when the temporary instrument point control unit 203 acquires the XY coordinate values of the current position of the surveyor's terminal device 12, the GPS coordinate values of the measurer's terminal device 12 are periodically used to obtain a predetermined number of GPS coordinate values (for example, , 5) Obtain and calculate the average value of the obtained predetermined number of GPS coordinate values. Since the GPS coordinate value is composed of the longitude in the X-axis direction and the latitude in the Y-axis direction, the temporary instrument point control unit 203 calculates the average value of the longitude and the latitude to obtain the GPS coordinate value. Calculate the average value. Then, the temporary instrument point control unit 203 acquires the average value of the calculated GPS coordinate values as the XY coordinate value of the current position of the surveyor's terminal device 12, that is, the XY coordinate value of the temporary instrument point. Thus, the measurement accuracy of the GPS coordinate values can be improved, and the XY coordinate values of the temporary instrument point can be acquired with high accuracy.

  Further, since the XY coordinate values of the current position of the surveyor's terminal device 12 are in the world geodetic system of GPS coordinates, the temporary instrument point control unit 203 next determines the acquired current position of the surveyor's terminal device 12. By converting the world geodetic system of the XY coordinate values into the survey coordinate system, the XY coordinate values of the current position of the surveyor terminal device 12 in the survey coordinate system are obtained. Specifically, the temporary instrument point control unit 203 uses the public reference points near the survey site registered in advance by the Geographical Survey Institute to determine the XY coordinate values of the public reference points of the world geodetic system and the public standard points of the survey coordinate system. A coordinate system difference indicating a difference between the point and the XY coordinate value is calculated. Here, since the XY coordinate values of the public reference point of the world geodetic system and the XY coordinate values of the public reference point of the survey coordinate system are composed of the X coordinate value and the Y coordinate value, the temporary instrument point control unit 203 , The coordinate system difference composed of the X difference and the Y difference is calculated by calculating the difference between the X coordinate value and the Y coordinate value. Then, the temporary instrument point control unit 203 calculates the current position of the surveyor's terminal device 12 in the survey coordinate system from the XY coordinate values of the current position of the surveyor's terminal device 12 in the world geodetic system based on the calculated coordinate system difference. To the XY coordinate values of

  In addition, when the surveyor grasps the installation position of the surveying instrument 10 at the survey site on the survey site drawing 605, the surveyor causes the surveyor terminal device 12 to display the survey site drawing 605. As shown in FIG. 8A, when the installation position of the surveying instrument 10 on the drawing 605 of the survey site is selected with the touch pen 800 or the tip of a finger, the temporary instrument point control unit 203 determines a point 801 near the tip of the touch pen 800 or the like. May be detected as a detection point, and the coordinate value (XY coordinate value) of the detection point 801 in the survey coordinate system may be acquired as the XY coordinate value of the temporary instrument point. Thus, the surveyor can easily acquire the XY coordinate values of the temporary instrument point using the drawing 605 of the survey site.

  When the temporary instrument point control unit 203 acquires the XY coordinate values of the temporary instrument point, the temporary instrument point control unit 203 stores the acquired XY coordinate values of the temporary instrument point in the data file 600. Here, when the coordinate values of the temporary instrument point are stored in the data file 600, “temporary instrument point” is stored in the point type 601 and “TS” (indicating the total station of the surveying instrument 10) is stored in the point name 602. The XY coordinate values of the coordinates of the temporary instrument point are stored as coordinates 603 in the survey coordinate system. Here, when the coordinates of the temporary instrument point are constituted by XY coordinate values, the XY coordinate values are stored, and when the coordinates of the temporary instrument point are constituted by XYZ coordinate values, the XYZ coordinate values are stored. You.

  Here, in FIG. 7B, the coordinates of the acquired temporary instrument point are displayed in the coordinates 708 of the temporary instrument point on the backward resection setting screen 705. Here, when the coordinates of the temporary instrument point are configured by XY coordinate values, the surveyor may manually input the Z coordinate value of the coordinates of the temporary instrument point.

  Next, as shown in FIG. 7B, a check box 709 for which the provisional direction angle has been set, a search unit key 710, a horizontal search range input field 711, and a vertical search A range input field 712 is displayed. The check box 709 for which the provisional direction angle has been set is a key for setting the provisional direction angle of the surveying instrument 10. The search unit key 710 is a key for designating a unit (length or angle) of a search range when the surveying instrument 10 searches for a target. The horizontal search range input field 711 is an input field for inputting a horizontal search range in designated search units. The vertical search range input field 712 is an input field for inputting a vertical search range in designated search units.

  Here, as shown in FIG. 8B, the surveyor sets the provisional direction angle of the surveying instrument 10 in the collimating direction of the telescope with the surveying instrument 10 installed. When the upward direction (or the forward direction) is made coincident, the gyro compass function built into the surveyor terminal device 12 causes the direction indicating the north of the gyro compass function to be the upper direction of the surveyor terminal device 12. The angle between them is calculated as the azimuth from north. Then, the surveyor sets the check box 709 (or the key in the check box 709) for which the temporary direction angle has been set, in a state where the upward direction of the surveyor's terminal device 12 matches the collimation direction of the surveying instrument 10. When selected, the search condition control unit 204 of the surveyor's terminal device 12 uses the gyrocompass function of the surveyor's terminal device 12 to set the azimuth of the surveyor's terminal device 12 to the north as the provisional direction angle of the surveying instrument 10. It is acquired (FIG. 3: S106). The reason why the azimuth angle of the surveyor terminal device 12 is set as the temporary direction angle of the surveying instrument 10 is that the actual direction angle of the surveying instrument 10 is determined by determining the XY coordinate values of the actual instrument point, as described later. To determine, the temporary direction angle of the surveying instrument 10 means the temporary direction angle of the surveying instrument 10 until the XY coordinate values of the actual instrument point are determined. Thereby, the surveyor can easily acquire the temporary direction angle of the surveying instrument 10.

  In the above description, the tentative direction angle of the surveying instrument 10 is set using the gyro compass function of the surveyor's terminal device 12, but other methods may be used. For example, the azimuth of the portable gyro compass may be set. By inputting the angle to the surveyor terminal device 12, the search condition control unit 204 may acquire the input azimuth as the temporary direction angle of the surveying instrument 10.

  Next, the surveyor selects a unit (for example, length) of the search range using the search unit key 710, and inputs a predetermined value (for example, 3 m) in the input field 711 of the horizontal search range and a vertical search. When a predetermined value (for example, 3 m) is input to the range input field 712, the search condition control unit 204 accepts an input of a horizontal and vertical search range (FIG. 3: S107). Then, based on the XY coordinate values of the temporary instrument point, the XY coordinate values of the reference point, and the search range, the search condition control unit 204 determines the relative distance between the temporary instrument point and the reference point, , The search angle of the swing of the surveying instrument 10 about the reference point is calculated for each reference point, and a reference point list in which the relative distance and the search angle are associated with each reference point is calculated (FIG. 3: S108).

  Here, the search angle has a horizontal direction and a vertical direction corresponding to the search range, and the horizontal search angle is, as shown in FIG. 8C, a direction from the temporary instrument point 802 to the reference point 803. A point 804 extending at a right angle from the reference point 803 in the horizontal direction by a horizontal search range is defined as a horizontal search end point, and a first straight line L1 between the temporary instrument point 802 and the reference point 803, and a temporary instrument point 802. And the second straight line L2 between the horizontal search end point 804 and the horizontal search end point 804. The vertical search angle is defined as a point 805 extending vertically from the reference point 803 by a vertical search range with respect to the direction from the temporary instrument point 802 to the reference point 803 in the vertical direction. It means twice the angle β formed by the first straight line L1 between the temporary instrument point 802 and the reference point 803 and the third straight line L3 between the temporary instrument point 802 and the vertical search end point 805. . The search condition control unit 204 includes a relative distance H (m) indicating the length of the first straight line L1, a horizontal search range A (m) indicating the length of the second straight line L2, and a third straight line. By substituting the vertical search range B (m) indicating the length of L3 into the following equations (1) and (2), the search angles 2α and 2β in the horizontal and vertical directions can be easily calculated. Can be done.

2α = tan ⁻¹ (A / H) * 2 (1)
2β = tan ⁻¹ (B / H) * 2 (2)

  Next, as shown in FIG. 9A, since the XY coordinate values of the temporary instrument points and the XY coordinate values of each reference point are stored in the data file 600 in association with each other, the search condition control unit 204 sets the data file 600 Is used to calculate a relative distance H between the temporary instrument point and the reference point with respect to a predetermined reference point (for example, “reference point 1”), and calculate the calculated relative distance H and the input horizontal direction. The search angles A and B in the horizontal and vertical directions are calculated by inputting the search ranges A and B in the vertical direction into the above equations (1) and (2). Then, the search condition control unit 204 stores the calculated relative distance 900 and the search angles 901 and 902 in the horizontal direction and the vertical direction in the data file 600. The search condition control unit 204 calculates a reference point list by calculating a relative distance 900 and horizontal and vertical search angles 901 and 902 for all the reference points stored in the data file 600. .

  Here, from the above equations (1) and (2), it is understood that the longer the relative distance H, the smaller the search angles 2α and 2β in the horizontal and vertical directions. Therefore, when the surveying instrument 10 searches for a target at a reference point where the relative distance H is long, the search time for swinging the surveying instrument 10 can be small, and the search time can be shortened.

  Note that the surveyor selects a unit (for example, an angle) of the search range using the search unit key 710, and sets a predetermined value (for example, 3 degrees) in the input field 711 of the horizontal search range and a vertical search range. When a predetermined value (for example, 3 degrees) is input to the input field 712, the search condition control unit 204 receives the input of the search range in the horizontal direction and the vertical direction (FIG. 3: S107), and The relative distance from the reference point is calculated, and the angle obtained by doubling the input horizontal and vertical search ranges (input angle) without using the above equations (1) and (2) is used as it is. The reference point list is calculated by calculating the search angles in the horizontal direction and the vertical direction (FIG. 3: S108).

  When the reference point list is calculated, the reference point selection control unit 205 of the surveyor's terminal device 12 allows the surveyor to select the reference points in the reference point list in ascending order of the relative distance H of the reference points. It is displayed on the terminal device 12 (FIG. 3: S109).

  The method by which the reference point selection control unit 205 displays the reference points in the reference point list is not particularly limited. For example, as shown in FIG. 9B, a back intersection measurement screen 903 for selecting a reference point includes a selection field 904 for the first selection reference point and detailed information 905 (XYZ coordinates and XYZ coordinates) of the first selection reference point. Target information), a collimation height input field 906 for the first selection reference point, a selection field 907 for the second selection reference point, and detailed information 908 (XYZ coordinates and target information) for the second selection reference point. , A collimation height input field 909 of the second selection reference point, and a measurement key 910 are displayed.

  Here, the reference point selection control unit 205 acquires a reference point having the longest relative distance 900 (for example, “reference point 2”) from among the relative distances 900 of the data file 600 as a first candidate reference point, and A reference point having the second largest distance 900 (for example, “reference point 3”) is acquired as a second candidate reference point. Then, the reference point selection control unit 205 first displays the first candidate reference point (“reference point 2”) in the first selection reference point selection field 904, and selects the second selection reference point selection field 907. First, the second candidate reference point (“reference point 3”) is displayed first. That is, the reference point selection control unit 205 sets the relative distance H between the first candidate reference point (“reference point 2”) and the second candidate reference point (“reference point 3”) to be longer on the backward intersection measurement screen 903. It is displayed so that it can be selected preferentially in order. Thus, the surveyor can easily select the reference point that shortens the search time according to the survey site.

  In the above description, the reference point selection control unit 205 preferentially displays the reference point having the long relative distance H, but may further add another condition. For example, in the backward intersection for determining the instrument point of the surveying instrument 10, as shown in FIG. 10A, a first reference point straight line LS1 between the instrument point 802 and the first selected reference point 1000, and the instrument point 802 and the second The angle γ of the rear intersection formed by the selected reference point 1001 and the second reference point straight line LS2 is important. In order to determine the instrument point of the surveying instrument 10 with high accuracy, the rear intersection angle γ is preferably in the range of 40 ° to 160 °, and more preferably in the range of 60 ° to 140 °. Therefore, the reference point selection control unit 205 sets the first reference point straight line LS1 between the XY coordinate values of the temporary instrument point and the XY coordinate values of the first candidate reference point among the reference points having the long relative distance H. The first intersection point γ formed by the second reference point line LS2 of the XY coordinate value of the temporary instrument point and the XY coordinate value of the second candidate reference point is in the range of 40 degrees to 160 degrees. The candidate reference point and the second candidate reference point may be displayed so as to be preferentially selected.

  In the first selection reference point selection field 904 and the second selection reference point selection field 907, the reference point of the reference point list can be selected, for example, in a pull-down format. By operating 904 and 907, the reference point selection control unit 205 calls up the reference points in the reference point list of the data file 600, and displays the first candidate reference point and the second candidate reference point displayed first with priority. A reference point other than a point is displayed so as to be selectable. Thus, the surveyor can arbitrarily select a desired reference point according to the survey site.

  Now, the surveyor selects the first reference point (“reference point 2”) in the first selection reference point selection field 904, and selects the second reference point (“reference point 2”) in the second selection reference point selection field 907. When “reference point 3” is selected (FIG. 3: S110 YES), the reference point selection control unit 205, from the data file 600, selects the first selection reference point (first selection reference point (904) selected in the first selection reference point selection field 904). The XYZ coordinates of the “reference point 2” and the target information are displayed in the detailed information 905 of the first selection reference point, and the second reference point (“reference point”) selected in the second selection reference point selection field 907 is displayed. 3)) the XYZ coordinates and the target information are displayed in the detailed information 908 of the second selected reference point. Thereby, the surveyor can confirm the detailed information of the two selected reference points. Note that the reference point selection control unit 205 uses target information (target type, prism constant, prism size) in the detailed information 905 of the first selected reference point and the detailed information 908 of the second selected reference point by the operation of the surveyor. ) May be changed.

  Then, the surveyor inputs a predetermined value in the collimation height input field 906 of the first selection reference point in accordance with the survey site, and also inputs a predetermined value in the collimation height input field 909 of the second selection reference point. When a predetermined value is input, the reference point selection control unit 205 receives the input of the input collimation height of the first selection reference point and the collimation height of the second selection reference point. In this way, the setting of the two selection reference points required for the backward association is completed.

  The selection of the two selection reference points may be appropriately designed according to the usage of the surveying instrument 10 and the surveying instrument terminal device 11. For example, when the surveying instrument 10 and the surveying instrument terminal device 11 are of a fixed type, two selection reference points are easily determined in principle, so that the first candidate reference point and the second candidate reference point are It may be configured to automatically select one of the selection reference points and the second selection reference point. On the other hand, when the surveying instrument 10 and the surveying instrument terminal device 11 are portable, since the installation location of the surveying instrument 10 can be changed as appropriate, the reference points other than the first candidate reference point and the second candidate reference point are used. May be arbitrarily selected.

  Then, when the surveyor selects the measurement key 907 (FIG. 3: S111 YES), the actual instrument point control unit 206 of the surveyor's terminal device 12 performs the following for each of the two selected reference point targets at the survey site. The surveying instrument 10 is automatically collimated using the temporary direction angle and the search angle of the surveying instrument 10, and the direction angle of the target of the selected reference point viewed from the surveying instrument 10, the target of the surveying instrument 10 and the target of the selected reference point. Then, the XY coordinate values of the actual instrument point of the surveying instrument 10 are calculated by measuring the distance between the XY coordinate values.

  The method by which the actual instrument point control unit 206 calculates the XY coordinate values of the actual instrument point is not particularly limited. For example, as shown in FIG. 10B, the actual instrument point control unit 206 performs the first selection from the surveying instrument 10 based on the XY coordinate values of the temporary instrument point 802 and the XY coordinate values of the first selection reference point 1002. A first direction angle C1 (degree) with respect to the reference point 1002 is calculated and transmitted to the surveying instrument terminal device 11 via the network 15.

  On the other hand, upon receiving the first direction angle C1, the surveying instrument terminal device 11 sets the surveying instrument 10 at the survey site based on the received first direction angle C1 at the first selection reference point 1002. The target 2b is rotated ((KK-2)) (FIG. 3: S112).

  Next, the actual instrument point control unit 206 calculates the horizontal and vertical search angles C2 (degrees) and C3 (degrees) with respect to the first selection reference point 1002 from the data file 600 via the network 15 using the surveying instrument. To the terminal device 11. Note that FIG. 10B shows the search angle C2 in the horizontal direction.

  On the other hand, the surveying instrument terminal device 11 causes the surveying instrument 10 to automatically collimate based on the received horizontal and vertical search angles C2 and C3 at the survey site (target search) (FIG. 3: S113).

  Then, as shown in FIG. 11A, when the surveying instrument 10 finds the target 2b installed at the first selection reference point 1002 (“KK-2”) and completes the automatic collimation, the surveying instrument 10 The direction angle C4 (degrees) and the distance C5 (m) between the surveying instrument 10 and the target 2b are measured (angle measurement, distance measuring), and the surveying instrument terminal device 11 The direction angle C4 and the distance C5 of the target 2b of the selection reference point 1002 are transmitted to the surveyor terminal device 12, and the actual instrument point control unit 206 of the surveyor terminal device 12 The direction angle C4 and the distance C5 of the target 2b are received and acquired (FIG. 3: S114).

  Here, since the direction angle and the distance of the second selection reference point have not yet been measured (NO in S115 in FIG. 3), the process returns to S112, and the actual instrument point control unit 206 returns to FIG. Based on the XY coordinate values of the temporary instrument point 208 and the XY coordinate values of the second selection reference point 1003, the surveying instrument 10 calculates a second direction angle D1 (degree) with respect to the second selection reference point 1003. Is transmitted to the surveying instrument terminal device 11 via the network 15. Upon receiving the second direction angle D1, the surveying instrument terminal device 11 sets the surveying instrument 10 at the surveying site based on the received second direction angle D1 at the second selection reference point 1003 (“KK-3”). ) To rotate the target 2c (FIG. 3: S112).

  Then, the actual instrument point control unit 206 transmits the horizontal and vertical search angles D2 (degrees) and D3 (degrees) with respect to the second selection reference point 1003 to the surveying instrument terminal device 11 via the network 15. Then, the surveying instrument terminal device 11 causes the surveying instrument 10 to automatically collimate at the surveying site based on the received horizontal and vertical search angles D2 and D3 (FIG. 3: S113).

  Here, as shown in FIG. 11A, when the surveying instrument 10 finds the target 2c set at the second selection reference point 1003 ("KK-3") and completes the automatic collimation, the surveyed target 2c , And the distance D5 (m) between the surveying instrument 10 and the target 2c are measured, and the surveying instrument terminal device 11 The direction angle D4 and the distance D5 are transmitted to the surveyor terminal device 12, and the actual instrument point control unit 206 of the surveyor terminal device 12 receives the direction angle D4 and the distance D5 of the second selection reference point 1003. And acquire it (FIG. 3: S114).

  Here, since the measurement of the directional angles C4 and D4 and the distances C5 and D5 of the two selection reference points 1002 and 1003 has been completed (FIG. 3: S115 YES), the actual instrument point control unit 206 determines the first selection reference point 1002 Based on the XY coordinate value, the direction angle C4 and the distance C5, and the XY coordinate value of the second selection reference point 1003, the direction angle D4 and the distance D5, the XY coordinate value of the actual instrument point of the surveying instrument 10 is calculated. (FIG. 3: S116). The calculation of the XY coordinate values of the actual instrument point may be performed by using a well-known backward resection method.

  Next, when the actual instrument point control unit 206 calculates the XY coordinate values of the actual instrument point, the XY coordinate values of the actual instrument point, the direction angle C4 of the first selection reference point 1002 to the target 2b, and the distance Based on C5, the XY coordinate value of the first selection reference point 1002 is calculated, and the calculated XY coordinate value of the first selection reference point 1002 is set as the calculated XY coordinate value. Using the XY coordinate values of the selected reference point 1002 as registered XY coordinate values, a first selected reference point difference indicating the difference between the calculated XY coordinate value of the first selected reference point 1002 and the registered XY coordinate value is calculated. It is determined whether or not one selected reference point difference is within a predetermined selected reference point determination value for determining the normality of the XY coordinate values of the instrument point (FIG. 3: S117).

  As a result of the determination, when the first selection reference point difference is within the selection reference point determination value (S117: YES), the actual instrument point control unit 206 determines that the XY coordinate values of the actual instrument point are normal. Then, selection of the general survey key 404 and the stakeout survey key 405 is permitted, and a measurement result screen is displayed.

  As shown in FIG. 11B, the measurement result screen 1100 displays the coordinates 1101 (XYZ coordinate values) of the actual instrument point, the calculated coordinates 1102 (including the calculated XY coordinate values) of the first selection reference point, and the first And a registration key 1104 are displayed. Thereby, the surveyor can confirm the measurement result obtained by the backcrossing.

  On the other hand, when the first selection reference point difference exceeds the selection reference point determination value (FIG. 3: S117NO), the actual instrument point control unit 206 determines that the XY coordinate values of the actual instrument point are abnormal, The selection of the general surveying key 404 and the stakeout surveying key 405 is prohibited, and transmission of the surveying instruction to the surveying instrument 10 is prohibited (lock processing is performed) (FIG. 3: S118).

  In this case, since the actual XY coordinate value of the instrument point is not accurately measured for some reason, there is a high possibility that the accuracy of the subsequent measurement will be poor. Forbidden to avoid surveying mistakes and prevent surveyors from surveying under wrong conditions. When the lock process is performed, the actual instrument point control unit 206 may display an error on the measurement result screen 1100 or notify the office terminal device 14 of the error, for example.

  Here, in order to release the lock processing, the process returns to S110, and the surveyor selects a combination of two selection reference points different from the combination of the two selection reference points selected earlier (FIG. 3: S110). ), The back intersection is performed again, the XY coordinate values of the new actual instrument point are calculated (FIG. 3: S116), the calculated XY coordinate values of the first selection reference point are calculated, and the first The selection reference point difference is determined (FIG. 3: S117), and the first selection reference point difference is within the selection reference point determination value (FIG. 3: S117 YES). By doing so, the actual instrument point control unit 206 can permit selection of the general survey key 404 and the stakeout survey key 405.

  In the above description, in order to determine the normality of the XY coordinate values of the actual instrument points, the actual instrument point control unit 206 calculates the XY coordinate values of the first selection reference point 1002, and Although the point difference was calculated and compared with the selection reference point determination value, it is not necessary to limit to this. For example, the actual instrument point control unit 206 determines the second selection reference point 1003 based on the XY coordinate values of the actual instrument point, the direction angle D4 of the second selection reference point 1003 to the target 2c, and the distance D5. May be calculated, a second selection reference point difference may be calculated from the XY coordinate values of the second selection reference point 1003, and the difference may be compared with the selection reference point determination value. Both the first selection reference point 1002 and the second selection reference point 1003 may be used.

  Now, when the surveyor selects the registration key 1104 on the measurement result screen 1100, the actual instrument point control unit 206 changes the “temporary instrument point” of the point type 601 of the data file 600 to “instrument point” as shown in FIG. 12A. Is updated to “point”, and the coordinates (including XY coordinate values) of the actual instrument point are stored in the coordinates 603 of “instrument point”. Then, when the coordinates of the actual instrument point are determined, the actual instrument point control unit 206 calculates and sets the actual direction angle of the surveying instrument 10 (FIG. 3: S119). When setting the actual direction angle of the surveying instrument 10, the actual instrument point control unit 206 may set the actual direction angle to 0 degrees with the telescope of the surveying instrument 10 facing north. This completes the instrument point measurement at the stage prior to the general survey or the stakeout survey.

  When the coordinates of the actual instrument point are stored (registered), the actual instrument point control unit 206 registers the coordinates (XYZ coordinate values) of the actual instrument point in the surveying instrument terminal device 11 via the network 15. Let it. Accordingly, when the surveyor selects the instrument registration coordinate key 706 on the back-rear setting screen 705, the temporary instrument point control unit 203 acquires the coordinates of the instrument point from the surveyor terminal device 11 or the surveyor terminal device 12. You can do it.

  At this time, since the coordinates and direction angle of the actual instrument point of the surveying instrument 10 and the XY coordinate value and the direction angle of the current position of the surveyor's terminal device 12 are known, the reference point display control unit 201 12B, the instrument point 1200 of the surveying instrument 10, the collimating direction 1201, the current position 1202 of the surveyor's terminal device 12, and the upward direction 1203 are displayed on the drawing 605 of the surveying site. In addition, the reference point display control unit 201 displays the azimuth angle 1204 of the gyrocompass function of the surveyor terminal device 12 on the drawing 605 of the survey site. This allows the surveyor to easily understand the positional relationship between the surveying instrument 10 and the surveyor's terminal device 12 at the surveying site.

<General survey>
FIG. 13 is a flowchart showing a general survey execution procedure according to the embodiment of the present invention. When the instrument point measurement is completed and the surveyor selects the general survey key 404 on the top screen 400, the input unit of the surveyor terminal device 12 accepts the selection of the general survey key 404 (FIG. 13: S201 YES), and The survey control unit 207 of the user terminal device 12 displays a general survey setting screen.

  On the general survey setting screen 1400, as shown in FIG. 14A, input of a general survey target observation point selection field 1401, observation point detailed information 1402 (XYZ coordinates and target information), and observation point collimation height are input. A column 1403 is displayed. Since the observation point has not been selected yet, nothing is displayed in the detailed information 1402 of the observation point.

  Here, in the observation point selection field 1401, points (reference points, observation points, etc.) registered in the data file 600 in advance are displayed so as to be selectable. If the desired observation point is registered in advance, the surveyor can select the desired observation point using the observation point selection field 1401.

  On the other hand, when the desired observation point is not registered, the surveyor may register the desired observation point on the spot and select the registered observation point in the observation point selection field 1401. Specifically, when the surveyor displays the drawing 605 of the survey site and selects a desired observation point on the drawing 605 of the survey site with the tip of a touch pen 1409 or a finger as shown in FIG. The display control unit 201 detects a point 1410 near the tip of the touch pen 1409 or the like as a detection point, and acquires the coordinates (XY coordinate values) of the detection point 1410 in the survey coordinate system. Then, the reference point display control unit 201 inquires of the surveyor about the type of the acquired coordinate point of the detection point 1410, and the surveyor determines the type of the detection point 1410 (for example, “observation point 1”). When input, as shown in FIG. 15A, the reference point display control unit 201 sets the “observation point 1” of the detection point 1410 in the point type 601 of the data file 600 and the detection point 1410 in the coordinates 603 of the “observation point 1”. (XY coordinate values) are stored. This allows the surveyor to easily add and register observation points. Note that, among the coordinates of the observation points, the Z coordinate value and the target information are stored in the data file 600 by being separately input by the surveyor.

  When the surveyor selects a predetermined observation point (“observation point 1”) in the observation point selection field 1401 (FIG. 13: S202 YES), the survey control unit 207 selects the observation point selected from the data file 600. The XYZ coordinates of (“observation point 1”) and the target information are displayed in the detailed information 1402 of the observation point. Then, the surveyor inputs the collimation height of the observation point into the input field 1403 in accordance with the survey site, and the survey control unit 207 displays the input value in the collimation height input field 1403 of the observation point. Thereby, the surveyor can confirm the detailed information of the selected observation point.

  In addition, as shown in FIG. 14A, the general survey setting screen 1400 includes a search unit key 1404, a horizontal search range input field 1405, a vertical search range input field 1406, and an observation point. A rotation key 1407 and a rotation key 1408 are displayed toward the tablet (the terminal device for surveyors 12). The rotation key 1407 for the observation point is a key for rotating the surveying instrument 10 toward the observation point, and the rotation key 1408 for the tablet is used to rotate the surveying instrument 10 to the surveyor terminal device 12 (tablet). It is a key for turning it toward.

  Here, the surveyor selects a unit (for example, length) of the search range using the search unit key 1404, and inputs a predetermined value (for example, 3 m) into the input field 1405 of the horizontal search range and a vertical search. When a predetermined value (for example, 3 m) is input to the range input field 1406, the survey control unit 207 accepts the input of the search range in the horizontal direction and the vertical direction, and receives the XY coordinate values of the actual instrument point and the observation point. Based on the XY coordinate values and the horizontal and vertical search ranges, the horizontal and vertical search angles that the surveying instrument 10 swings around the observation point as viewed from the surveying instrument 10 are calculated ( (FIG. 13: S203). The method for calculating the search angle is the same as that described above, and a description thereof will be omitted.

  Furthermore, when the surveyor selects either the rotation key 1407 toward the observation point or the rotation key 1408 toward the tablet, the survey control unit 207 rotates the surveying instrument 10 in a predetermined direction (FIG. 13: S204).

  Here, as shown in FIG. 15B, the surveyor sets the target 2d at the observation point (“observation point 1”) at the survey site, and selects the rotary key 1507 toward the observation point in that state. Then, based on the XY coordinate values of the actual instrument point and the XY coordinate values of the observation point (“observation point 1”), the survey control unit 207 sends a direction from the surveying instrument 10 to the observation point (“observation point 1”). The angle is calculated and transmitted to the surveying instrument terminal device 11 via the network 15. Then, the surveying instrument terminal device 11 rotates the surveying instrument 10 to the target 2d of the observation point (“observation point 1”) based on the direction angle of the observation point (“observation point 1”). As described above, the surveyor can automatically rotate the surveying instrument 10 toward the target 2d of the observation point (“observation point 1”) by operating the key, and the surveyor manually operates the surveying instrument 10. There is no need to rotate, and a single surveyor can easily and efficiently proceed with the survey.

  Further, as shown in FIG. 15B, the surveyor sets the target 2d at the observation point ("observation point 1") at the survey site, brings the surveyor terminal device 12 near the target 2d, and sets the target 2d. In the state where the surveyor's terminal device 12 is present in the vicinity of, the rotation key 1408 is selected toward the tablet. Then, the surveying control unit 207 obtains the XY coordinate values of the current position of the surveyor's terminal device 12 in the world coordinate system from the GPS function of the surveyor's terminal device 12, and obtains the surveyor terminal device 12 in the surveying coordinate system. XY coordinate values of the current position of the surveyor terminal device 12 in the survey coordinate system are regarded as the XY coordinate values of the observation point (“observation point 1”). Of the observation point (“observation point 1”) from the surveying instrument 10 based on the XY coordinate values of the observation point (“observation point 1”) and the XY coordinate values of the observation point (“observation point 1”). It is transmitted to the terminal device 11. Then, the surveying instrument terminal device 11 rotates the surveying instrument 10 to the target 2d of the observation point (“observation point 1”) based on the direction angle of the observation point (“observation point 1”). As described above, the surveyor carrying the surveyor's terminal device 12 operates the keys in a state where the surveyor is present near the target 2d installed at the observation point (“observation point 1”), so that the surveying instrument 10 is operated. Since it is possible to automatically rotate and measure the target 2d at the observation point (“observation point 1”), the surveyor does not need to manually rotate the surveying instrument 10 even in this case, A single surveyor can easily and efficiently proceed with the survey.

  Next, the survey control unit 207 automatically collimates the surveying instrument 10 with respect to the target 2d of the observation point (“observation point 1”) at the survey site using the search angle of the observation point (“observation point 1”). (FIG. 13: S205). Here, since the surveying instrument 10 has already rotated in the direction of the target 2d, the surveying instrument 10 can easily collimate the target 2d.

  Then, the surveying control unit 207 displays a general surveying measurement screen. As shown in FIG. 16A, on the general survey measurement screen 1600, an observation point selection field 1601, an automatic tracking start key 1602, a single measurement start key 1603, and a continuous measurement start key 1604 are displayed. Since the surveyor has already selected the observation point ("observation point 1") on the general survey measurement screen 1600, the observation point selected by the surveyor ("observation point 1") is displayed in the observation point selection field 1601. ) Is displayed, but also on this screen, the surveyor can operate the selection field 1601 to change another observation point.

  Here, when the surveyor slightly moves the target 2d of the observation point (“observation point 1”), if the automatic tracking start key 1602 is selected (YES in S206 in FIG. 13), the survey control unit 207 causes the collimated target 2d to move. Is automatically tracked by the surveying instrument 10. Thereby, fine adjustment of the position of the target 2d is possible. On the other hand, when the surveyor does not select the automatic tracking start key 1602 (FIG. 13: NO in S206), the survey control unit 207 keeps the surveying instrument 10 automatically collimated to the target 2d.

  Then, when the surveyor performs the single measurement, when the single measurement key 1603 is selected (FIG. 13: S207 YES), the surveying control unit 207 causes the surveying instrument 10 to set the target 2 d of the observation point (“observation point 1”). The XY coordinate values are measured (FIG. 12: S208). The measurement of the XY coordinate values of the target 2d is the same as the measurement by the usual surveying instrument 10. This completes the measurement of the observation point (“observation point 1”).

  When the measurement of the observation point is completed, the measurement result 1605 (XYZ coordinate values, oblique distance, vertical angle, horizontal angle) of the observation point and the registration key 1606 are displayed on the general survey measurement screen 1600, as shown in FIG. 16A. It is displayed (FIG. 13: S209). Note that the survey control unit 207 calculates the oblique distance, horizontal angle, and vertical angle of the coordinates of the observation point from the XY coordinate values of the observation point, and displays the result in the measurement result 1605 of the observation point. Thereby, the surveyor can confirm whether the measurement result of the observation point is good or not.

  Here, when the single measurement key 1603 is selected, the survey control unit 207 completes the measurement of the observation point (“observation point 1”) by the surveying instrument 10 (FIG. 13: S210NO). On the other hand, when the surveyor has selected the continuous measurement start key 1604 instead of the single measurement key 1603 (FIG. 13: S210 YES), the survey control unit 207 returns to S208 and sends the XY of the target 2d to the surveying instrument 10. The coordinate values are periodically measured (FIG. 13: S208), and the XY coordinate values of the target 2d of the measured observation point are periodically updated and displayed (FIG. 12: S209). This enables continuous measurement. Here, it is preferable that the measurement result of the continuous measurement is stored in the storage unit as a history and can be checked later. When the surveyor wants to stop the continuous measurement, the survey control unit 207 stops the continuous measurement by selecting the continuous measurement start key 1604 again (FIG. 13: S210NO).

  Then, when the surveying apparatus 10 performs the automatic tracking, the surveyor selects the automatic tracking start key 1602 again, and the surveying control unit 207 causes the surveying apparatus 10 to stop the automatic tracking (FIG. 13: S211 YES). On the other hand, when the surveyor has not selected the automatic tracking start key 1602, the survey control unit 207 does not particularly perform a stop process (FIG. 12: S211 NO).

  When the surveyor wants to register the measurement result, he selects the registration key 1606 on the general surveying measurement screen 1600, and the surveying control unit 207 gives the surveyor a point name of the observation point to be registered (“observation point 1”). When the surveyor inputs the point name of the observation point (for example, “KS-1”), the survey control unit 207 transmits the observation point “observation point” of the point type 601 in the data file 600 as shown in FIG. 16B. “KS-1” is stored in the point name 602 of “1”, and the coordinates of the measurement result are stored in the coordinates 603 of “observation point 1” (FIG. 13: S212 YES). Thereby, the observation point to be surveyed can be registered. If the surveyor does not register the survey result, he or she need not select the registration key 1606 (FIG. 13: NO in S212).

<Stakeout survey>
FIG. 17 is a flowchart for illustrating an execution procedure of the pile driving survey according to the embodiment of the present invention. When the instrument point measurement is completed, the surveyor selects the stakeout survey key 405 on the top screen 400, and the input unit of the surveyor terminal device 12 accepts the selection of the stakeout survey key 405 (FIG. 17: YES in S301). The survey control unit 207 displays a stakeout survey setting screen.

  As shown in FIG. 18A, on the stakeout survey setting screen 1800, a selection column 1801 of an observation point (pileout point) to be stakeout, detailed information 1802 (XYZ coordinates and target information) of the observation point, and an observation point And a collimation height input field 1803 are displayed. Since the observation point has not been selected yet, nothing is displayed in the detailed information 1802 of the observation point.

  Here, in the observation point selection column 1801, points (reference points, observation points, and the like) registered in the data file 600 in advance are selectably displayed as described above. If the desired observation point is registered in advance, the surveyor selects the desired observation point using the observation point selection field 1801. If the desired observation point is not registered, the surveyor registers the desired observation point by selecting a predetermined position on the drawing 605 of the survey site in the same manner as described above.

  When the surveyor selects a predetermined observation point (“observation point 2”) in the observation point selection field (FIG. 17: S302), the survey control unit 207 selects the observation point (“observation point”) from the data file 600. The XYZ coordinates of the “observation point 2”) and the target information are displayed in the detailed information 1802 of the observation point. Then, the surveyor inputs the collimation height of the observation point into the input column 1803 in accordance with the survey site, and the survey control unit 207 displays the input value in the collimation height input column 1803 of the observation point. Thereby, detailed information of the observation point (pile driving point) to be piled up can be obtained.

  Also, as shown in FIG. 18A, the general survey setting screen 1800 includes an input field 1804 for guidance sensitivity, an input field 1805 for guidance display maximum distance, a search unit key 1806, and an input field 1807 for search range in the horizontal direction. A vertical search range input field 1808, a rotation key 1809 toward the stakeout point, a rotation key 1810 toward the tablet, and an automatic tracking start key 1811 are displayed.

  The guidance sensitivity means a predetermined range centered on the observation point (stakeout point). If the target position is within the range of the guidance sensitivity centered on the stakeout point, the target is located at the stakeout point. If the target position is outside the guidance sensitivity range, it is determined that the target has not yet approached the stakeout point. The guidance display maximum distance means the maximum memory for guidance display. The rotation key 1809 is a key for rotating the surveying instrument 10 toward the stakeout point, and the rotation key 1810 is a button for rotating the surveying instrument 10 toward the stakeout point. It is a key for rotating toward.

  Here, the surveyor inputs a predetermined value (for example, 5 mm) in the input field 1804 for guidance sensitivity and a predetermined value (for example, 1000 mm) in the input field 1805 for guidance display maximum distance. A step 207 sets the guiding conditions for the stakeout survey based on the input values (FIG. 17: S303).

  The surveyor selects a unit (for example, length) of the search range using the search unit key 1706, and inputs a predetermined value (for example, 3 m) into the input field 1707 of the horizontal search range and a vertical search range. When a predetermined value (for example, 3 m) is input to the input field 1708, the survey control unit 207 receives the input of the search range in the horizontal direction and the vertical direction, and inputs the XY coordinate values of the actual instrument point and the observation point. Based on the XY coordinate values and the horizontal and vertical search ranges, horizontal and vertical search angles that the surveying instrument 10 swings around the observation point as viewed from the surveying instrument 10 are calculated (FIG. 17: S304). The method for calculating the search angle is the same as that described above, and a description thereof will be omitted.

  Next, the surveyor selects one of the rotation key 1809 toward the stakeout point and the rotation key 1810 toward the tablet, and the surveying control unit 207 rotates the surveying instrument 10 in a predetermined direction. (FIG. 17: S305).

  Here, the selection of the rotation key 1809 toward the stakeout point is the same as the selection of the rotation key 1407 toward the observation point, as described above. That is, when the surveyor sets the target at the observation point at the surveying site and selects the rotary key 1809 toward the stakeout point in this state, the survey control unit 207 determines the XY coordinate value of the actual instrument point and the observation value. The surveying instrument 10 is rotated to the target of the observation point based on the XY coordinate values of the point (“observation point 2”). In addition, the selection of the rotation key 1810 for the tablet is the same as the selection of the rotation key 1408 for the tablet, as described above, and a description thereof will be omitted. Thus, as described above, the surveyor does not need to manually rotate the surveying instrument 10, and the surveying can be easily and efficiently performed by one surveyor.

  Next, the survey control unit 207 performs automatic collimation on the surveying instrument 10 using the search angle of the observation point (“observation point 2”) with respect to the target of the observation point (“observation point 2”) at the survey site. (FIG. 17: S306). Here, since the surveying instrument 10 has already rotated in the direction of the target, the surveying instrument 10 can easily collimate the target.

  Furthermore, when the surveyor selects the automatic tracking start key 1811 (FIG. 17: S307 YES), the survey control unit 207 causes the surveying instrument 10 to automatically track the collimated target. This prepares for stakeout surveying. On the other hand, when the surveyor does not select the automatic tracking start key 1811 (FIG. 17: S307 NO), the survey control unit 207 does not proceed to the next processing in the stakeout survey.

  When the surveying instrument 10 is automatically tracking the target, the surveying control unit 207 displays a stakeout surveying measurement screen. As shown in FIG. 18B, a stakeout surveying measurement screen 1812 displays a selection field 1813 for a stakeout target observation point, a continuous measurement start key 1814, and a single measurement start key 1815.

  On the stakeout surveying measurement screen 1812, since the surveyor has already selected the observation point, the observation point selected by the surveyor (“observation point 2”) is displayed in the observation point selection column 1813. Also on this screen, the surveyor can operate the selection field 1813 to change the observation point.

  Next, when the surveyor selects the continuous measurement start key 1814 (FIG. 17: YES in S308), the survey control unit 207 changes the continuous measurement start key 1814 to a continuous measurement stop key and sends the observation point ("observation") to the surveying instrument 10. The XY coordinate values of the target at point 2 ") are measured (FIG. 17: S309). The method of measuring the XY coordinate values of the target is the same as described above. Then, when the surveying instrument 10 completes the measurement of the XY coordinate values of the target at the observation point, the survey control unit 207 receives the measurement coordinates of the observation point from the surveying instrument 10 via the network, and sets the guidance conditions (the guidance conditions). A stakeout survey result screen is displayed based on the sensitivity and the maximum distance of the guidance display) and the measurement coordinates of the observation point (FIG. 17: S310).

  As shown in FIG. 18B, the stakeout survey result screen 1816 includes a stakeout point guidance display 1817 in the X-axis direction and the Y-axis direction, a display type selection column 1818, a display unit selection column 1819, and a one-way Is displayed. The stakeout point guidance display 1817 in the X-axis direction and the Y-axis direction displays the difference between the registered XY coordinate value of the observation point input in advance and the measured XY coordinate value of the measured observation point in the X-axis direction and the Y-axis direction. This is a display indicated by a directional arrow, and the set guidance display maximum distance is displayed as the maximum memory. The stakeout point guidance display 1817 in the X-axis direction and the Y-axis direction may be a numerical display of the difference in addition to the intuitive arrow display, or, for example, “Xmm forward to the stakeout point and Ymm to the right. , Etc., the minimum information may be displayed. In the display type selection field 1818, a display type such as "front / rear / left / right" or "east / west / north / north" can be selected. In a display unit selection field 1819, a display unit such as “m” or “mm” can be selected. The stakeout point guidance display 1820 in one direction is a display indicating a direction in which the difference between the registered XY coordinate value and the measured XY coordinate value of the observation point is larger in either the X-axis direction or the Y-axis direction. This allows the surveyor to easily grasp where the current position of the target is with respect to the stakeout point.

  Here, the surveyor does not select the continuous measurement stop key in order to adjust the current position of the target to the stakeout point (registered coordinates of the observation point) while viewing the stakeout measurement result screen 1816 (FIG. 17: 312), the target is moved (FIG. 17: 313). Then, the surveying instrument 10 automatically tracks the moving target, returns to S309, and periodically measures the XY coordinate values of the target (FIG. 17: 309). This allows the surveyor to match the current position of the target to the stakeout point. Here, in the continuous measurement, since the measurement results of the XY coordinate values of the target are obtained periodically, it is preferable that the measurement results are stored in the storage unit as a history and can be checked later.

  Here, when the surveyor moves the target greatly, and the surveying instrument 10 loses track of the target during automatic tracking, the survey control unit 207 determines whether the observation point at the first or most recent measurement (“observation point 2”) ), The surveying instrument 10 may be rotated in the direction of the observation point (“observation point 2”). Thereby, even if the surveying instrument 10 loses track of the target during automatic tracking, the surveying control unit 207 rotates the surveying instrument 10 in the direction of the previous observation point (“observation point 2”) to return to the original state. To return, the surveyor can easily start over.

  Now, when the surveyor brings the target's current position close to the stakeout point and the difference between the registered XY coordinate value and the measured XY coordinate value of the observation point falls within the range of the guidance sensitivity, the X-axis direction and the Y-axis direction , And the stakeout point guidance display 1820 in one direction disappears. Here, when the surveyor wants to stop the continuous measurement, when the continuous measurement stop key is selected, the survey control unit 207 changes the continuous measurement stop key to the continuous measurement start key 1814, and the surveying instrument 10 performs the continuous measurement. It is stopped (FIG. 17: 311 YES).

  If the surveyor wants to register the measurement result (measurement coordinates of the observation point), he selects the registration key on the stakeout survey measurement screen 1812, and the survey control unit 207 gives the surveyor a point name of the observation point to be registered. When the surveyor inputs the point name of the observation point (for example, “KS-2”), the survey control unit 207 sets the point name 602 of the observation point “observation point 2” of the point type 601 in the data file 600 to “ The measurement coordinates of the measurement result are stored in the coordinates 603 of “KS-2” and “observation point 2” (FIG. 17: 313 YES). As a result, the observation point of the stakeout survey target can be registered, which can be used for confirming an error. If the surveyor does not register the survey result, he or she need not select the registration key (FIG. 17: 313 NO).

  Since the single measurement start key 1815 is provided on the stakeout measurement screen 1812, the surveyor selects the single measurement start key 1815 in S308 as necessary (FIG. 17: S308 YES). The surveying control unit 207 causes the surveying instrument 10 to measure the XY coordinate values of the target at the observation point (“observation point 2”) (FIG. 17: S309). In this case, every time the surveyor moves the target (FIG. 17: S312), the single-shot measurement start key 1815 is selected to execute the measurement (FIG. 17: S308 YES).

<Schedule survey>
FIG. 19 is a flowchart showing a procedure for executing the schedule survey according to the embodiment of the present invention. When the surveyor selects the schedule key on the top screen 400 to measure a plurality of reference points (check points) at a predetermined time, the input unit of the surveyor terminal device 12 accepts the selection of the schedule key ( (FIG. 19: 401 YES), the schedule control unit 208 displays a schedule survey setting screen.

  On the schedule survey setting screen 2000, as shown in FIG. 20A, a schedule acquisition key 2001, a check point setting selection field 2002, an add key 2003, a delete key 2004, a point name change key 2005, and an up key 2006 is displayed.

  When the surveyor selects the schedule acquisition key 2001, the schedule control unit 208 acquires a check point stored in the schedule file in association with the schedule time (FIG. 19: 402). Here, at this time, there is no check point stored with the schedule time associated with the schedule time, so nothing is displayed in the check point setting selection field 2002.

  When the surveyor selects the add key 2003 to add a check point, the schedule survey setting screen 2007 displays a reference point selection field 2008, a schedule time input field 2009, and a schedule time input field 2009 as shown in FIG. 20A. A search unit key 2010, a horizontal search range input field 2011, a vertical search range input field 2012, an additional key 2013 at a check point, and a schedule set key 2014 are displayed.

  Here, for example, the surveyor selects a predetermined reference point (“reference point 2”) in the reference point selection field 2008 and inputs a predetermined time (“t1”) in the schedule time input field 2009. “Length” is selected by the search unit key 2010, a predetermined value (for example, 3 m) is input to the input field 2011 of the horizontal search range, and a predetermined value (for example, 3m) is input to the input field 2012 of the vertical search range. , 3m), and select an additional key 2013 at the check point.

  Then, the schedule control unit 208 adds the selected reference point as a check point (FIG. 19: 403 YES). Specifically, the schedule control unit 208 refers to the schedule file 2015. As shown in FIG. 20B, a schedule 2016 and a check point 2017 are stored in the schedule file 2015 in association with each other. As in the data file 600, items of the check point 2017 include a point type, a point name, coordinates in a survey coordinate system, target information, a relative distance, and horizontal and vertical search angles. The schedule control unit 208 inputs the input schedule time (“t1”) to the schedule 2016, and selects the type of the check point 2017 corresponding to the input schedule time (“t1”). The stored reference point (“reference point 2”) is stored in association with the reference point. As described above, the reference point (“reference point 2”) is stored in association with the schedule 2016 of the schedule file 2015, so that the selected reference point is added as the check point 2017.

  Next, the schedule control unit 208 calculates the XY coordinate values of the actual instrument point, the XY coordinate values of the selected reference point (“reference point 2”), and the input horizontal and vertical search ranges. Based on this, the horizontal and vertical search angles are calculated (404 in FIG. 19). The method for calculating the search angle is the same as that described above, and a description thereof will be omitted. Then, the schedule control unit 208 associates the calculated values with the search angles in the horizontal direction and the vertical direction among the items of the reference point (“reference point 2”) of the check point 2017 in the schedule file 2015 and stores them. As described above, the surveyor can change the information in the checkpoint 2017 of the schedule file 2015 as appropriate. On the other hand, among the items at the check points 2017, items that do not require input reflect, for example, information stored in the data file 600.

  When a reference point is added to a check point, the added reference point (“reference point 2”) is selected in the check point setting selection field 2002, and detailed information 2002a (for example, The XYZ coordinates of the reference point and the target information) are displayed. Thus, the surveyor can check the detailed information 2002a of the reference point of the check point.

  When the surveyor selects the delete key 2004 in a state where a predetermined reference point is selected in the check point setting selection field 2002, the schedule control unit 208 selects the check point 2017 of the schedule file 2015 from the check point 2017. Delete the reference point. When the surveyor selects the point name change key 2005, the schedule control unit 208 receives the point name from the surveyor and changes the point name of the selected reference point. Further, when there are a plurality of reference points in the check point setting selection field 2002, when the surveyor selects the move key 2006, the schedule control unit 208 selects the selected reference point among the plurality of reference points. To change the display order. The order of display corresponds to the order of scheduled surveys.

  Here, in order to select a plurality of reference points existing around the surveying instrument 10 without selecting the schedule set key 2014 (FIG. 19: 405 NO), and further selecting the additional key 2003, the surveyor The input schedule time (“t1”) is displayed in the time input field 2009. The surveyor selects a predetermined reference point (“reference point 3”) in the reference point selection field 2008, selects “length” with the search unit key 2010, and sets the predetermined length in the horizontal search range input field 2011. (For example, 3 m), and a predetermined value (for example, 3 m) in the input field 2012 for the vertical search range, and an additional key 2013 is selected as a check point.

  Then, the schedule control unit 208 stores the selected reference point (“reference point 3”) in association with the type of the check point 2017 corresponding to the schedule time (“t1”) of the schedule 2016, The selected reference point is added as a check point (FIG. 19: 403 YES). Also, the schedule control unit 208 calculates the search angles in the horizontal direction and the vertical direction (404 in FIG. 19), and among the items of the reference point (“reference point 3”) of the check point 2017, the horizontal and vertical directions are determined. The calculated value is stored in association with the search angle. Thereby, two reference points are added as check points.

  In the schedule survey, a predetermined number (or all) of the reference points existing around the surveying instrument 10 may be measured. Therefore, when the schedule time (“t1”) is input, the schedule control unit 208 In the schedule file 2015, a predetermined number of reference points registered in advance may be automatically added as check points to the input schedule time ("t1").

  In the schedule survey, a predetermined number (or all) of the reference points need to be periodically measured. Therefore, the surveyor may input a predetermined reference point (“reference point” 2)), enter another time (“t2”) in the schedule time input field 2009, make the other input values the same, and select the additional key 2013 at the check point. Then, the schedule control unit 208 stores the selected reference point (“reference point 2”) in association with the type of the check point 2017 corresponding to the schedule time (“t2”) of the schedule 2016, The selected reference point is added as a check point (FIG. 19: 403 YES). In this way, by associating the check points with other schedule times, it is possible to measure a predetermined number of reference points at a plurality of schedule times.

  Then, when the surveyor selects the schedule set key 2014 (FIG. 19: 405 YES), the schedule control unit 208 starts the schedule survey, and the schedule 2016 in the schedule file 2015 has not yet arrived at the current time. The latest schedule time (eg, “t1”) with no schedule time and earliest arrival is selected as the target time (FIG. 19: 406), and whether or not the current time reaches the target time (“t1”) (407 in FIG. 19).

  If the result of the determination is that the current time has not reached the target time ("t1") (FIG. 19: 407 NO), the schedule control unit 208 returns to S407 and repeats the determination of the target time ("t1").

  On the other hand, as a result of the determination, when the current time has reached the target time (“t1”) (407 in FIG. 19), the schedule control unit 208 checks the check point (“t1”) associated with the schedule time of the target time (“t1”). For example, the surveying instrument 10 performs the measurement of “reference point 2” and “reference point 3” (FIG. 19: 408). Specifically, the schedule control unit 208 determines one check point (“reference point 2”) among the check points (“reference point 2” and “reference point 3”) associated with the target time (“t1”). ), And instructs the actual instrument point control unit 206 to measure the selected check point ("reference point 2"). The actual instrument point control unit 206 first, as shown in FIG. Is rotated to the target 2b of the check point (“reference point 2”), and the surveying instrument 10 is automatically collimated based on the horizontal and vertical search angles with respect to the check point (“reference point 2”). Since the target 2b is set at the check point (“reference point 2”), when the surveying instrument 10 finds the target 2b at the check point (“reference point 2”) and completes the automatic collimation, the search is performed. The directional angle (degree) and distance of the target 2b at the check point (“reference point 2”) are measured, and the XY coordinate values of the target 2b at the check point (“reference point 2”) are measured. The actual instrument point control unit 206 acquires the XY coordinate values of the target 2b at the check point (“reference point 2”).

  Here, if there is an error in the measurement result of the check point (“reference point 2”) (FIG. 19: 409 YES), the actual instrument point control unit 206 causes the surveyor terminal device 12 to display the error, An error is notified to the office terminal device 14 (FIG. 19: 410). For example, when the surveying instrument 10 cannot find the target at the check point due to the occurrence of an obstacle, the surveying instrument 10 detects reflected light from the target due to a change in the surveying site. You can mention the case where you could not do it.

  When the measurement of the XY coordinate values of one check point is completed, the schedule control unit 208 sets another check point (“reference point 3”) associated with the schedule time of the same target time (“t1”). It is determined whether it exists (FIG. 19: 411).

  As a result of the determination, when there is another check point (“reference point 3”) associated with the schedule time of the same target time (“t1”) (FIG. 19: 411 YES), the schedule control unit 208 proceeds to S408. Returning, the schedule control unit 208 returns the remaining unselected check points (“reference points”) among the check points (“reference point 2” and “reference point 3”) associated with the target time (“t1”). 3 ”), and the actual instrument point control unit 206 rotates the surveying instrument 10 to the target 2c at the check point (“ reference point 3 ”) as shown in FIG. Then, the XY coordinate values of the target 2c at the check point (“reference point 3”) are measured.

  If there is no other checkpoint associated with the schedule time of the same target time (“t1”) (FIG. 19: 411 NO), the schedule control unit 208 sets the schedule that has not yet arrived at the current time. It is determined whether or not the time exists (FIG. 18: 412). Specifically, the schedule control unit 208 determines whether or not there is a schedule time that has not yet arrived with respect to the current time among the schedules 2016 of the schedule file 2015 and the latest schedule time that has arrived earliest. Is determined.

  As a result of the determination, if there is a schedule time that has not yet arrived with respect to the current time and there is a latest schedule time that has arrived earliest (FIG. 19: 412 YES), the schedule control unit 208 returns to S406, The schedule time is selected as a target time (for example, “t2”) (FIG. 19: 406), and it is determined whether the current time reaches the target time (“t2”) (FIG. 19: 407). ).

  Then, when the current time reaches the target time ("t2") (FIG. 18: 407 YES), the schedule control unit 208 checks the schedule associated with the target time ("t2") as shown in FIG. 21B. The measurement of the points (for example, “reference point 2” and “reference point 3”) is performed by the surveying instrument 10 (408 in FIG. 19). This makes it possible to repeatedly measure a predetermined number of reference points at a plurality of schedule times.

  On the other hand, in S412, when there is no schedule time that has not yet arrived with respect to the current time (FIG. 19: 412 NO), the schedule control unit 208 completes the processing. Here, the measurement result of the schedule survey is stored in the storage unit as a history at each schedule time, and can be confirmed later.

  In this way, even if the surveyor is not at the surveying site, the measurement of a predetermined number of check points is automatically completed simply by setting a schedule. Therefore, for example, before the surveyor visits the surveying site, the surveying instrument 10 can measure two check points in advance and automatically perform the back-to-back association. After this measurement, the surveyor can calculate the actual instrument point of the surveying instrument 10 using the measurement results of the two check points, and can immediately start the general survey or the stakeout survey. For example, the surveyor sets the schedule time at 7:00 am for the two check points of the backcrossing, and causes the surveying instrument 10 to measure the two check points from this time. Sometimes when you arrive at the surveying site, you can immediately start a general survey or a stakeout survey since the measurements at the two checkpoints have been completed.

  In addition, for example, all reference points existing around the surveying instrument 10 at the survey site are set as check points, the schedule time is set to 9:00 pm at all check points, and all the survey points are set to the surveying instrument 10 from this time. Checkpoint measurement is performed. That is, in the nighttime, the surveying instrument 10 measures all the check points. Then, the surveyor first goes to the survey site in the morning, confirms the measurement results of all the check points, and determines a reference point that can be used for surveying among the plurality of reference points. This makes it possible to measure the reference point to be checked in the daytime at night, thereby shortening the surveyor's time for surveying. Furthermore, by periodically measuring a predetermined number (or all) of the reference points as check points, the system can be used for periodic dynamic observation of the predetermined number of reference points.

<Data communication>
FIG. 22 is a flowchart showing a procedure for executing data communication according to the embodiment of the present invention. In the above description, the specific description of the data communication between the surveying instrument 10 and the surveyor's terminal device 12 is omitted, but basically, it is performed as follows. That is, for example, when the surveyor terminal device 12 (sender) transmits a predetermined command (for example, a measurement instruction) to the surveyor 10 (receiver) (FIG. 22: S501 YES), the surveyor terminal device 12 Generates a message corresponding to the command (measurement instruction) (FIG. 22: S502).

  Next, the surveyor's terminal device 12 writes a message to a predetermined database (called a topic, here, “topic 1”) provided in advance in the server 13 via the network 15 (FIG. 22: S503). . As shown in FIG. 23, the server is provided with a plurality of topics, and has a dedicated topic “topic 1” when the surveyor terminal device 12 causes the surveyor 10 to perform processing. 12 writes a message to a dedicated topic "topic 1". Thereby, the process of the surveyor's terminal device 12 is completed.

  On the other hand, the surveying instrument terminal device 11 connected to the surveying instrument 10 periodically accesses the dedicated topic “topic 1” of the server 13 via the network 15 (FIG. 22: S504), and It is determined whether the latest message has been written to "1" (FIG. 22: S505).

  If the result of the determination is that the latest message has not been written (FIG. 22: S505 NO), the surveying instrument terminal device 11 returns to S504 and again periodically accesses the dedicated topic “topic 1” of the server 13. Then, the latest message is determined (FIG. 22: S504) (FIG. 22: S505).

  On the other hand, if the result of the determination is that the latest message has been written (FIG. 22: S505 YES), the surveying instrument terminal device 11 acquires the latest message (FIG. 22: S506), and The command is converted into a command that can be executed by the surveying instrument 10 (FIG. 22: S507) and transmitted to the surveying instrument 10. When receiving the command, the surveying instrument 10 executes a process (measurement instruction) based on the received command (FIG. 22: S508). As described above, the surveyor terminal device 12 causes the surveying instrument 10 to execute the process via the dedicated topic “topic 1” of the server 13.

  On the other hand, when the surveying instrument 10 transmits a predetermined command (for example, a measurement result) to the surveyor's terminal device 12 (FIG. 22: S501YES), the above-described sender and receiver are reversed. That is, the surveying instrument terminal device 11 generates a message corresponding to the command (measurement result) of the surveying instrument 10 (FIG. 22: S502), and the dedicated topic of the server 13 via the network 15 (“topic 2”). The message is written in (FIG. 22: S503).

  On the other hand, the surveyor's terminal device 12 periodically accesses the dedicated topic (“topic 2”) of the server 12 via the network 15 (FIG. 22: S504), and the dedicated topic (“topic 2”). )) (S505 in FIG. 22), and if the latest message has been written (YES in S505 in FIG. 22), the terminal device 12 for the surveyor uses the latest message. Is acquired (FIG. 22: S506), the acquired latest message is converted into a command (FIG. 22: S507), and processing (measurement result) is executed based on the command (FIG. 22: S508). If the command is a measurement result, the surveyor's terminal device 12 updates or displays the measurement result.

  Such a method of performing data communication using a dedicated topic is called a Pub / Sub messaging model. This Pub / Sub messaging model has the advantage that the sender can send data to multiple recipients simultaneously. For example, by configuring the terminal device 12 for the surveyor and the terminal device 14 for the office to access a dedicated topic (“topic 2”) for writing a message of the measurement result, the terminal device 12 for the surveyor The office terminal device 14 can simultaneously share the latest measurement results at the survey site. This allows not only the surveyor but also a third party such as a supervisor to immediately confirm the latest measurement result at the survey site using the office terminal device 14, and the surveying time of the surveyor and the third party The time lag between the time of confirmation and the time of confirmation can be eliminated.

  Furthermore, two surveyor terminal devices 12 are prepared, and the two surveyor terminal devices 12 send messages to a dedicated topic (“topic 3”) that the surveyor terminal device 11 causes the surveyor 10 to process. 24, two surveyor terminal devices 12 can share one surveying instrument 10 at the same surveying site and perform two different surveys, as shown in FIG. As a result, the result of the survey performed by one surveyor can be shared by the two surveyors, and the efficiency of the surveying work in a wide range of surveying sites can be improved. In the above description, two surveyor terminal devices 12 share one surveying device 10, but three or more surveyor terminal devices 12 may share one surveying device 10. Absent.

  In the above-described Pub / Sub messaging model, the terminal device 11 for the surveying instrument and the terminal device 12 for the surveyor perform data communication via the server 13, which is effective in terms of sharing the result. However, the communication speed may be slow. Therefore, when it is desired to perform higher-speed communication, the terminal device for surveyor 12 may be configured to directly communicate with the terminal device for surveyor 11 without going through the server 13. In this case, for example, it is suitable for continuous measurement of stakeout survey requiring high-speed communication.

  In the embodiment of the present invention, the CAD file is a two-dimensional drawing drawn in the XY coordinate system of the survey coordinate system, but may be a three-dimensional drawing drawn in the XYZ coordinate system of the survey coordinate system.

  As described above, according to the present invention, it is necessary to perform general surveying and stakeout surveying, since a single surveyor can easily and efficiently perform calculations from actual instrument point calculation to surveying. The present invention can be applied to certain general structures, buildings, equipment, ground, roads, vehicles, railways, and other measurement fields, civil engineering fields, surveying fields, and the like.

  In the embodiment of the present invention, the measurement is started by selecting the measurement key by the surveyor. However, a remote controller capable of wireless communication with the surveyor terminal device 12 is provided, and a button of the remote controller is provided. The measurement key may be associated with the measurement key and the measurement key may be selected by pressing the button of the remote controller. Thus, in a general survey or a stakeout survey, a single surveyor can easily start a measurement by setting a target at a selected point and pressing a button on a remote controller. Further, a voice recognition unit is provided in the surveyor terminal device 12, various keys and voices are associated in advance, and the surveyor emits voices corresponding to the predetermined keys, so that the voice recognition unit May be configured to select a key corresponding to the voice of (1). Thereby, one surveyor can easily start the measurement by emitting a sound in the general survey or the stakeout survey.

  In the embodiment of the present invention, the surveyor's terminal device 12 is configured to include each unit. However, a program that realizes each unit may be stored in a storage medium, and the storage medium may be provided. In this configuration, the program is read by a predetermined processing device, and the processing device realizes each unit. In that case, the program itself read from the recording medium has the operational effects of the present invention. Further, the steps executed by each unit can be provided as the automatic surveying method of the present invention.

  As described above, the automatic surveying system and the automatic surveying method according to the present invention require general surveying and stakeout surveying, general structures, buildings, equipment, ground, roads, vehicles, railways, and the like. Automatic surveying system and automatic surveying that are useful in the measurement field, civil engineering field, surveying field, etc., and can easily and efficiently perform the calculation from actual instrument point calculation to surveying with one surveyor It is effective as a method.

A reference point display control step of causing the surveyor terminal device to display a plurality of reference points having XY coordinate values registered in advance on the XY coordinate system of the drawing of the survey site where the surveying instrument is installed;
A tilt angle control step of determining whether or not the XY tilt angle of the surveying instrument is within a predetermined XY determination value;
When the XY tilt angle is within the XY determination value, a temporary instrument point control step of acquiring an XY coordinate value of the temporary instrument point of the surveying instrument in an XY coordinate system of the drawing of the survey site,
When an input of a search range is received from a surveyor, an XY coordinate value of the temporary instrument point, an XY coordinate value of the reference point, and a search between the temporary instrument point and the reference point based on the search range. The relative distance and the search angle of the swing of the surveying instrument around the reference point viewed from the surveying instrument are calculated for each reference point, and the relative distance and the search angle are calculated for each reference point. A search condition control step of calculating an associated reference point list;
A reference point selection control step of displaying the reference point of the reference point list on the terminal for the surveyor so that the relative distance of the reference point can be selected in descending order,
When two reference points among the reference points in the reference point list are received from the surveyor as two selected reference points, the provisional survey of the surveying instrument is performed for each of the targets of the two selected reference points in the surveying site. Automatically collimate the surveying instrument using the direction angle and the search angle of the reference point, the direction angle of the target of the selected reference point viewed from the surveying instrument, and the surveying instrument and the selected reference point An actual instrument point control step of calculating an XY coordinate value of an actual instrument point of the surveying instrument by measuring a distance to a target;
When a target is set at a predetermined observation point in the survey site by a surveyor and the XY coordinate value of the observation point in the XY coordinate system of the drawing of the survey site is received from the surveyor, the XY coordinate value of the actual instrument point is obtained. And a survey control step of rotating the surveying instrument to the target of the observation point based on the XY coordinate value of the observation point, and causing the surveying instrument to measure the XY coordinate value of the target of the observation point.
