For example, a voice recognition function is provided. The start instruction used may be used.

  In the following, for convenience of explanation, CAD (Computer Aided Design) data relating to a plurality of measurement points 58 included in a specific section in the map has already been acquired by the CPU 60 via the network 50 and stored in the secondary storage unit 64. The explanation is based on the assumption that Here, the specific section refers to, for example, a section to which one plane rectangular coordinate is assigned by the Geographical Survey Institute. The CAD data includes station coordinates that are plane rectangular coordinates of each of the plurality of station 58 and station identification information that can uniquely identify the station coordinates. As an example of the station identification information, an identification number given in advance to each of the station 58 can be cited.

  Further, hereinafter, for convenience of explanation, a case will be described in which instrument point coordinates that are plane rectangular coordinates of the instrument point 38 in a specific section are already stored in the secondary storage unit 64. In the following description, for convenience of explanation, the description will be made on the assumption that the smart device 14 is held in a specific posture by the holder 56. In the following, for convenience of explanation, an angle for rotating the surveying instrument main body 44 in the horizontal direction is referred to as “horizontal rotation angle”, and an angle for rotating the surveying instrument main body 44 in the vertical direction is referred to as “vertical rotation angle”. Further, for convenience of explanation, the explanation will be made on the assumption that the irradiation light receiving unit 16 is operating in the surveying instrument 12.

  In the first surveying assistance process shown in FIG. 5, first, in step 150, the acquisition unit 22 determines whether or not the touch panel 72A has received the station identification information. If the touch panel 72A does not accept the station identification information at step 150, the determination is denied and the determination at step 150 is performed again. If the touch panel 72A accepts the station identification information at step 150, the determination is affirmed and the routine proceeds to step 152.

  Hereinafter, for convenience of explanation, the station 58 identified by the station identification information received by the touch panel 72A in Step 150 is referred to as “target station 58A”. In the following description, for convenience of explanation, the positive direction of the Y axis of the smart device 14 is set to the instrument point 38 from the time when the station identification information is received in step 150 until the movement angle is calculated in step 180 described later. The explanation is based on the premise that they are facing each other.

  In step 152, the acquisition unit 22 acquires the station coordinates of the target station 58A. The station coordinates acquired in step 152 are an example of survey target coordinates according to the present invention.

  In the next step 154, the control unit 26 transmits capture instruction information for instructing the surveying instrument 12 to capture the prism 48 to the surveying instrument 12. Here, the capture of the prism 48 refers to a state in which the light receiving unit 16B receives reflected light when the laser beam L is irradiated onto the prism 48 by the light irradiation unit 16A.

  In the next step 156, the control unit 26 determines whether or not the capture information transmitted by the process of the later-described step 214 being executed by the surveying instrument control unit 20 is received. If it is determined in step 156 that capture information has not been received, the determination is negative and the process proceeds to step 158. If the capture information is received at step 156, the determination is affirmed and the routine proceeds to step 166.

  In step 158, the control unit 26 determines whether or not the uncaptured information transmitted by the processing of the later-described step 204 is executed by the surveying instrument control unit 20. If the uncaptured information is not received in step 158, the determination is negative and the process proceeds to step 156. If uncaptured information is received at step 158, the determination is affirmed and the routine proceeds to step 160.

  In step 160, the control unit 26 determines whether or not the orientation information transmitted as a result of the process in step 206 described later being executed by the surveying instrument control unit 20 has been received. Here, the orientation information refers to information indicating the current orientation of the surveying instrument main body 44, that is, the rotation angle of the surveying instrument main body 44 in the current horizontal direction. The orientation information refers to, for example, information indicating the rotation angle in the horizontal direction of the surveying instrument main body 44 when a state in which the front of the surveying instrument main body 44 is directly opposed to the origin of a specific section is 0 degree.

  If the direction information is not received in step 160, the determination is negative and the determination in step 160 is performed again. If the orientation information is received at step 160, the determination is affirmed and the routine proceeds to step 162.

  In step 162, the control unit 26 calculates a horizontal rotation angle required for causing the irradiation direction of the laser light L from the light irradiation unit 16 </ b> A to face the station 58 specified by the station coordinates acquired in step 152. . The horizontal rotation angle is calculated based on the instrument point coordinates, the point coordinates acquired in step 152, and the orientation information received in step 160. The instrument point coordinates and the orientation information received in step 160 are an example of irradiation light receiving unit information according to the present invention.

  In the next step 164, the control unit 26 transmits the rotation angle information indicating the horizontal rotation angle calculated in step 162, and then proceeds to step 156. Note that the rotation angle information transmitted in step 164 is an example of instruction information according to the present invention.

  In step 166, the control unit 26 transmits survey start instruction information for instructing the surveying instrument 12 to start surveying to the surveying instrument 12.

  In the next step 168, the control unit 26 determines whether or not the surveying information transmitted by the process of the step 220 described later being executed by the surveying instrument control unit 20 has been received. Here, the survey information refers to information indicating a distance measurement value and an angle measurement value which are survey results by the surveying instrument 12. The distance measurement value indicates an oblique distance from the irradiation light receiving unit 16 to the prism 48, and the angle measurement value indicates a horizontal rotation angle and a vertical rotation angle from the reference point to the prism 48.

  In step 168, when surveying information is not received, determination is denied and determination of step 168 is performed again. If the survey information is received at step 168, the determination is affirmed and the routine proceeds to step 170.

  In step 170, the control unit 26 calculates a current position coordinate that is a plane rectangular coordinate of the current position from the instrument point coordinates and the survey information received in step 168. The “current position coordinates” referred to here is an example of current position specifying information according to the present invention.

  In the next step 172, the control unit 26 calculates a movement distance that is a distance required for the movement from the current position coordinates calculated in step 170 to the target measurement point 58 </ b> A. Then, the control unit 26 stores (overwrites and saves) the calculated moving distance in the moving distance storage area 62A. The moving distance stored in the moving distance storage area 62A is an example of the distance according to the present invention.

  In the next step 174, the control unit 26 calculates a magnetic north angle that is an angle of magnetic north in the XY plane based on the detection result of the geomagnetic sensor 88. Here, the XY plane refers to an XY plane in the smart device 14 in which the positive direction of the Y axis of the smart device 14 is 0 degree.

  In the next step 176, the control unit 26 determines whether or not the magnetic north angle calculated in step 174 is the initial magnetic north angle. The initial magnetic north angle refers to the magnetic north angle calculated in step 174 for the first time after the station identification information is received in step 150.

  Incidentally, in the magnetic north angle storage area 62B, an initial set angle (for example, 10000 degrees) predetermined as an angle that cannot be actually calculated is stored, and the magnetic north angle is stored (overwritten and saved) in step 178 described later. The The stored content of the magnetic north angle storage area 62B is reset to the initial set angle when, for example, new station identification information is received in step 150. Therefore, in step 176, whether or not the magnetic north angle calculated in step 174 is the initial magnetic north angle is determined based on whether or not the initial set angle is stored in the magnetic north angle storage area 62B. That is, in this step 176, when the initial set angle is stored in the magnetic north angle storage area 62B, it is determined that the magnetic north angle calculated in step 174 is the initial magnetic north angle.

  In step 176, when the magnetic north angle calculated in step 174 is the initial magnetic north angle, the determination is affirmed and the routine proceeds to step 178. In step 176, if the magnetic north angle calculated in step 174 is not the initial magnetic north angle, the determination is negative and the routine proceeds to step 182.

  In step 178, the control unit 26 stores (overwrites) the magnetic north angle calculated in step 174 in the magnetic north angle storage area 62B.

  In the next step 180, the control unit 26 determines from the instrument point coordinates, the station coordinates acquired in step 152, and the current position coordinates calculated in step 170 from the current position in the XY plane to the target station 58A. The movement angle which is an angle required for the movement of is calculated. Then, the control unit 26 stores (overwrites and saves) the calculated movement angle in the movement angle storage area 62C, and then proceeds to step 186. The movement angle stored in the movement angle storage area 62C is an example of a direction according to the present invention.

  In step 182, the control unit 26 calculates a magnetic north angle difference. Here, the magnetic north angle difference refers to an angle difference obtained by subtracting the magnetic north angle calculated in step 174 from the initial magnetic north angle stored in the magnetic north angle storage area 62B.

  In the next step 184, the control unit 26 updates the movement angle stored in the movement angle storage area 62C based on the magnetic north angle difference calculated in step 182. That is, the control unit 26 stores in the movement angle storage area 62C as the latest movement angle the angle obtained by subtracting the magnetic north angle difference calculated in Step 182 from the movement angle stored in the movement angle storage area 62C (overwriting). save.

  Here, a specific example of the method of updating the movement angle will be described with reference to FIG. FIG. 8 is a state transition diagram illustrating an example of a state in which the smart device 14 transitions in the order of the first arrangement example → the second arrangement example. In the first arrangement example and the second arrangement example shown in FIG. 8, for convenience of explanation, the holder stands in a direction opposite to the positive direction of the Y axis of the smart device 14 (the negative direction of the Y axis). The description will be made on the assumption that the pin pole 46 is held in the direction.

  As an example, as shown in FIG. 8, the first arrangement example is an arrangement example of the smart device 14 in which the positive direction of the Y axis is directed to the instrument point 38. In the first arrangement example, the magnetic north angle calculated in step 174 is 315 degrees, and the movement angle calculated in step 180 is 270 degrees. The second arrangement example is different from the first arrangement example in that the smart device 14 is rotated 90 degrees counterclockwise about the center point O as an axis. In the second arrangement example, the magnetic north angle calculated in step 174 is 45 degrees.

  Here, if the magnetic north angle shown in the first arrangement example is the initial magnetic north angle, the magnetic north angle difference calculated in step 182 is 270 degrees (= 315 degrees-45 degrees). In this case, in step 184, 0 degree which is an angle obtained by subtracting 270 degrees of the magnetic north angle difference from 270 degrees of the movement angle shown in the first arrangement example is moved as the latest movement angle (updated movement angle). It is stored in the angle storage area 62C.

  In step 186, the control unit 26 displays the moving distance calculated in step 172 and the moving direction which is an example of information related to the direction according to the present invention on the display 72 </ b> B, and outputs the sound by the speaker 74. Note that the moving distance and moving direction that are displayed on the display 72B and that are output by sound from the speaker 74 are examples of guidance information according to the present invention.

  Here, the moving direction refers to a direction uniquely determined from the moving angle stored in the moving angle storage area 62C. In step 186, for example, in the case of the first arrangement example shown in FIG. 8, an arrow indicating the direction rotated 270 degrees clockwise relative to the positive direction of the Y axis is displayed on the display 72B and calculated in step 172. The distance traveled is displayed. In addition, a message “Please move XXX meters to the left” is output by voice from the speaker 74. Thus, when the moving direction is presented by the speaker 74, the direction on the assumption that the holder is positioned in the negative direction of the Y axis of the smart device 14 and is directly facing the display 72B is audibly displayed. The

  In the case of the second arrangement example shown in FIG. 8, for example, since the positive direction of the Y axis corresponds to the moving direction, an arrow indicating the positive direction of the Y axis is displayed on the display 72B and calculated in step 172. The distance traveled is displayed. In addition, a message “Please move YYY meters forward” is output by voice from the speaker 74.

  In the next step 188, the control unit 26 determines whether or not the station coordinates acquired in step 152 and the current position coordinates calculated in step 170 match within a predetermined range (for example, within 10 millimeters). judge. In step 188, if the station coordinates acquired in step 152 and the current position coordinates calculated in step 170 do not match within a predetermined range, the determination is negative and the routine proceeds to step 154. In step 188, if the station coordinates acquired in step 152 and the current position coordinates calculated in step 170 match within a predetermined range, the determination is affirmed and the routine proceeds to step 190.

  In step 190, the control unit 26 determines whether or not the position of the target measurement point 58A is an unphotographed position. The unphotographed position refers to a position that has not yet been photographed by the camera 67 in step 192 described later. Whether or not the position of the target measurement point 58A is an unphotographed position is determined based on whether or not later-described shooting information including the measurement specifying information received in step 150 is stored in the secondary storage unit 64.

  In step 190, when the position of the target measurement point 58A specified by the measurement specifying information received in step 150 is an unphotographed position, the determination is affirmed and the process proceeds to step 192. In step 190, if the position of the target measurement point 58 </ b> A specified by the measurement specification information received in step 150 is a position already captured by the camera 67, the determination is negative and the process proceeds to step 196.

  In step 192, the control unit 26 performs photographing with the camera 67. Here, the image acquired by the camera 67 is an image showing the target measuring point 58A side.

  In the next step 194, the control unit 26 stores the shooting information in the secondary storage unit 64. The shooting information includes the image acquired by the camera 67 in step 186, the station identification information received in step 150, and the current time acquired from the RTC 65 when the processing in step 188 is executed. Refers to information associated with each other.

  In the next step 196, the control unit 26 determines whether or not a condition for ending the first surveying assistance process is satisfied. The condition for ending the first survey assistance process is, for example, a condition that an instruction to end the first survey assistance process is received by the hard key 70 and the touch panel 72A, or a predetermined condition after the execution of the first survey assistance process is started. It refers to the condition that time (for example, 1 hour) has passed.

  In step 196, if the condition for ending the first surveying assistance process is not satisfied, the determination is negative and the routine proceeds to step 154. If the prism 48 is not captured by the surveying instrument 12 (step 158: Y), the rotation angle information is retransmitted to the surveying instrument 12 by executing the processing of step 164.

  In step 196, if the condition for ending the first surveying assistance process is satisfied, the determination is affirmed and the first surveying assistance process is terminated.

  Next, the first surveying instrument side processing performed by the CPU 90 when the CPU 90 executes the first surveying instrument side program 98 when the start condition of the first surveying instrument side process is satisfied will be described with reference to FIG. To do. In addition, as an example of the start condition of the first surveying instrument side process, there is a condition that the main power switch of the surveying instrument 12 is turned on. As another example of the start condition of the first surveying instrument side process, there is a condition that the trigger signal transmitted from the smart device 14 is received when the start instruction of the first surveying auxiliary process is received by the touch panel 72A. .

  In the first surveying instrument side processing shown in FIG. 7, in step 200, the surveying instrument control unit 20 determines whether or not the capture instruction information transmitted by executing the processing of step 154 by the control unit 26 has been received. judge. If the capture instruction information is not received at step 200, the determination is negative and the determination at step 200 is performed again. If the capture instruction information is received at step 200, the determination is affirmed and the routine proceeds to step 202.

  In step 202, the surveying instrument control unit 20 determines whether the prism 48 is captured. If the prism 48 is captured in step 202, the determination is affirmed and the routine proceeds to step 214.

  In the next step 208, the surveying instrument control unit 20 determines whether or not the rotation angle information transmitted by the processing of the step 164 being executed by the control unit 26 has been received. If the rotation angle information is received at step 208, the determination is affirmed and the routine proceeds to step 210. If the rotation angle information is not received in step 208, the determination is negative and the determination in step 208 is performed again.

  In step 210, the surveying instrument control unit 20 determines whether or not the horizontal rotation angle indicated by the rotation angle information received in step 208 is not 0 degrees. In step 210, if the horizontal rotation angle indicated by the rotation angle information received in step 208 is not 0 degrees, the determination is affirmative and the routine proceeds to step 212. In step 210, when the horizontal rotation angle indicated by the rotation angle information received in step 208 is 0 degree, the determination is negative and the routine proceeds to step 213.

  In step 212, the surveying instrument control unit 20 drives the horizontal direction driving unit 108 to rotate the surveying instrument main body 44 in the horizontal direction by the horizontal rotation angle indicated by the rotation angle information received in step 208. As a result, before the prism 48 reaches the target measurement point 58A, the light irradiation unit 16A is in front of the target measurement point 58A in the horizontal direction.

  In the next step 213, the surveying instrument control unit 20 determines whether or not the prism 48 is captured. If the prism 48 is captured in step 213, the determination is affirmed and the routine proceeds to step 214. If the prism 48 is not captured in step 213, the determination is negative and the determination in step 213 is performed again.

  Although illustration is omitted, if the determination is initially negative in step 213, the surveying instrument control unit 20 has rotated the surveying instrument main body 44 in the horizontal direction by the horizontal rotation angle indicated by the rotation angle information. The rotation completion information shown is transmitted to the smart device 12. Upon receiving the rotation completion information, the smart device 12 transmits search instruction information for instructing the surveying instrument 12 to search for the prism 48. The CPU 90 executes the predetermined control program (not shown) on the condition that the search instruction information is received by the Wi-Fi interface 112, thereby moving the surveying instrument main body 44 in the horizontal direction and the vertical direction until the prism 48 is captured. Rotate in the direction.

  In step 214, the surveying instrument control unit 20 transmits capture information indicating that the prism 48 is captured to the smart device 14.

  In the next step 216, the surveying instrument control unit 20 determines whether or not the surveying start instruction information transmitted by executing the processing of step 166 by the control unit 26 has been received. If the surveying start instruction information is not received in step 216, the determination is negative and the determination in step 216 is performed again. In step 216, when surveying start instruction information is received, the determination is affirmed and the process proceeds to step 218.

  In the next step 220, the surveying instrument control unit 20 transmits the distance measurement value obtained by the distance measurement and the angle measurement performed in step 218 and the survey information indicating the angle measurement value to the smart device 14.

  In the next step 222, the surveying instrument control unit 20 determines whether or not a condition for ending the first surveying instrument side processing is satisfied. The conditions for ending the first surveying instrument-side process are, for example, a condition that an instruction to end the first surveying instrument-side process is received by the receiving unit 102, or a predetermined time after the execution of the first surveying auxiliary process is started. It refers to the condition that (for example, 1 hour) has passed.

  If the condition for ending the first surveying instrument side processing is not satisfied at step 222, the determination is negative and the routine proceeds to step 200. In step 222, if the condition for ending the first surveying instrument side processing is satisfied, the determination is affirmed and the first surveying instrument side processing is ended.

  Next, the second survey assistance process performed by the CPU 60 when the CPU 60 executes the second survey assistance program 68 when the start condition of the second survey assistance process is satisfied will be described with reference to FIG. As an example of the start condition of the second survey assistance process, the condition that the main power switch of the smart device 14 is turned on, or the start instruction of the second survey assistance process by the touch panel 72A when the main power switch is turned on.

Hereinafter, for convenience of explanation, the current position of the smart device 14 is referred to as “device current position”.

  In the next step 256, the control unit 26 determines whether or not the distance calculated in step 254 is less than a predetermined distance (for example, 2000 m). The predetermined distance is, for example, a distance that is equal to or less than an upper limit distance that can be optically captured by the prism 48 and that falls within the specific section described above. The predetermined distance used in this step 256 may be a fixed value, or may be a variable value that can be customized in accordance with an instruction received by the hard key 70 or the touch panel 72A.

  As described above, in the smart device 14, the control unit 26 obtains the horizontal rotation angle based on the instrument point coordinates, the orientation information, and the measurement point coordinates (step 162). Then, rotation angle information indicating the obtained horizontal rotation angle is transmitted to the surveying instrument 12 by the control unit 26 (step 164). In the surveying instrument 12, the horizontal driving unit 108 is controlled by the surveying instrument control unit 20 to rotate the irradiation light receiving unit 16 at a horizontal rotation angle indicated by the rotation angle information transmitted by the smart device 14 (step 212). ). Therefore, the surveying system 10 can reduce the labor required for the work of directing the irradiation light receiving unit 16 toward the target measurement point 58A.

  In the smart device 14, the moving distance and moving direction are displayed on the display 72 </ b> B, and the moving distance and moving direction are output by sound from the speaker 74 (step 186).

However, the present invention is not limited to this. For example, the control unit 26 obtains the angle obtained by subtracting the initial magnetic north angle from the angle obtained by adding the latest magnetic north angle to the movement angle stored in the movement angle storage area 62C as the latest movement angle (after the update). (Movement angle). As described above, the movement angle is not updated based on the integrated value of the angular velocity detected by the angular velocity sensor 86, but may be updated according to the change amount of the magnetic north angle.

  In the above-described embodiment, the case where the shooting information is stored in the secondary storage unit 64 is illustrated. However, the present invention is not limited to this. For example, the shooting information is transmitted to the external device via the network 50. You may be made to do.

  Moreover, although the case where CPU60 calculated GPS information was illustrated in the said embodiment, this invention is not limited to this. For example, when a device with a GPS function such as a PC or other smart device equipped with a GPS function is connected to the external interface 82, the CPU 60 may acquire GPS information from the device with a GPS function.

  Moreover, although the case where CPU60 acquires CAD data via the network 50 was illustrated in the said embodiment, this invention is not limited to this. For example, the CPU 60 may acquire CAD data from an external device connected to the external interface 82.

  Moreover, although the said embodiment demonstrated on the assumption that the geomagnetic sensor 88 was incorporated in the smart device 14, this invention is not limited to this. For example, when the geomagnetic sensor 88 is not built in the smart device 14, an external geomagnetic sensor may be connected to the external interface 82. In this case, the CPU 60 may calculate the magnetic north angle with reference to the magnetic north detected by the external geomagnetic sensor.

  Moreover, in the said embodiment, although the case where CPU60 calculated the present position coordinate based on surveying information was illustrated, this invention is not limited to this. For example, the CPU 60 may provide instrument point coordinates and survey information to an external electronic computer connected to the external interface 82 to the smart device 14 to acquire the current position coordinates calculated by the external electronic computer. Further, the movement distance and the movement angle may be calculated by an external computer. In this way, the calculation load of the CPU 60 is reduced by causing the external computer connected to the smart device 14 to calculate the current position coordinates, the movement distance, the movement angle, and the like, and the CPU 60 obtaining the calculation result.

  Further, in the above embodiment, the case where the movement distance and the movement direction are presented in step 186 is exemplified, but the present invention is not limited to this, and for example, the movement distance after the processing of step 194 is executed. In addition, the moving direction may be presented.

  Moreover, although the said embodiment showed the case where a moving distance and a moving direction were shown with the display 72B and the speaker 74, this invention is not limited to this. For example, the moving distance or moving direction may be presented. Further, at least one of the movement distance and the movement direction may be presented by the display 72B or the speaker 74.

  Moreover, although the case where the moving distance and the moving direction are presented by the display 72B and the speaker 74 mounted on the smart device 14 is illustrated in the above embodiment, the present invention is not limited to this. For example, at least one of the movement distance and the movement direction may be presented using a presentation device of an external device that is connected to the external interface 82 and used. As an example of an external device presentation device used by being connected to the external interface 82, a display and a speaker of another smart device, a display and a speaker of a PC, or a display and a speaker of a wearable terminal device can be given.

  In the above embodiment, the smart device 14 has been described as an example, but the present invention is naturally applicable to a portable PC or a wearable terminal device.

  Moreover, in the said embodiment, although the survey assistance program and the surveying instrument side program were illustrated, this is an example to the last. Therefore, it goes without saying that unnecessary steps may be deleted, new steps may be added, and the processing order may be changed within a range not departing from the spirit.
