The distance measuring unit 207 includes a light transmitting unit that emits distance measuring light, and a light receiving unit that receives the reflected light reflected by the object to be measured after being irradiated with the distance measuring light from the light transmitting unit. A prism, which is a retroreflective member provided on, for example, a pinpole, is used as the object to be measured. Note that the object to be measured is not limited to the retroreflective member, and is not limited to other reflecting members (for example, , a reflective sheet, a target plate, a wall, etc.).

The distance measurement unit 207 measures the distance (oblique distance) from the surveying instrument 2 to the measurement object by emitting distance measurement light, for example, pulsed laser light, and receiving reflected light reflected by the measurement object. Note that the distance measurement method is not limited to such a pulse method, and it is also possible to apply a well-known method such as a so-called phase difference method that measures distance based on the number of waves of laser light.

The tracking light transmitting/receiving unit 208 is a light source capable of irradiating the measurement target with tracking light. The tracking light transmitting/receiving unit 208 has a light receiving element such as an image sensor (such as a CCD sensor or a CMOS sensor) that receives part of the tracking light reflected by the measurement target and converts it into an electric signal. The control unit 211 controls the horizontal rotation driving unit 205 and the vertical rotation driving unit 206 so that the light receiving element of the tracking light transmitting/receiving unit 208 continues to receive the tracking light emitted from the light source.

The surveying instrument 2 also includes a horizontal angle detection unit 209 (horizontal encoder) for detecting the horizontal rotation angle of the telescope unit 24 (that is, the rotation angle about the vertical axis), and the vertical rotation angle of the telescope unit 24. (that is, the angle of rotation about the horizontal axis), and a vertical angle detection unit 210 (vertical encoder). The surveying instrument 2 incorporates a distance measuring unit 207 including a distance measuring optical system, and part of the optical path of the distance measuring optical system of this distance measuring unit 207 is shared with part of the optical system of the telescope. The light emitted from the distance measuring unit 207 or the tracking light transmitting/receiving unit 208 is guided from the object side of the telescope unit 24 coaxially with the collimation axis and emitted.

The control unit 211 also controls the angles (horizontal angle and vertical angle) detected by the horizontal angle detection unit 209 and the vertical angle detection unit 210, the distance (oblique distance) measured by the distance measurement unit 207, the tracking light transmission/reception unit 208 acquires, stores, and calculates various types of information such as an image captured, and causes the display unit 203 and the display unit 304 of the device control device 3 to display the acquisition result and the calculation result, for example. Further, the control unit 211 performs drive control of each unit according to the operation on the operation unit 204 or according to the calculation result.

The device control device 3 can transmit and receive information to and from the surveying device 2 via the communication unit 302 . The input unit 303 is an operation unit capable of inputting various operation instructions and settings. For example, the operation instructions may include power ON/OFF switching, surveying start trigger, surveying mode switching, surveying cycle setting, surveying device 2 (equipment) selection command, and the like. The input unit 303 can include arbitrary operation devices and input devices such as switches, buttons, and dials according to the form of the device control device 3 . In addition, the equipment control device 3 can remotely control the surveying device 2 according to an input operation on the input unit 303, acquire information such as the survey result of the surveying device 2, and display it on the display unit 304. . The display unit 304 can display an image or the like captured by the tracking light transmitting/receiving unit 208 . Note that when the display unit 304 is a touch panel, the display unit 304 and the input unit 303 may be formed integrally. The storage unit 305 stores information such as the correspondence table 41 and the device control program 42 .

The device control device 3 also includes a computer (not shown) for controlling the device control device 3 . The device control program 42 can also be stored, for example, in a computer-readable storage medium (or storage device) of the device control device 3 .

FIG. 3 is a configuration diagram of the correspondence table 41. As shown in FIG. The correspondence table 41 stores device identification information 411 and grade information 412 in correspondence. The device identification information 411 can be the model name, type, product number, series name, manufacturing number, etc. of the surveying device 2 . The device identification information 411 can optionally include letters, numbers, and symbols.

The grade information 412 is type information classified according to the measurement accuracy (for example, angle measurement accuracy) of the surveying instrument 2 . The surveying device 2 can use different contents and purposes of surveying work depending on the grade (class). In the present embodiment, the case where the device connected to the device control device 3 is the surveying device 2 is described, and as the grade information 412, for example, "1st grade", "2nd grade" or "3rd grade" is stored. .

Next, the device control method executed by the device control device 3 will be described with reference to the control flowchart of FIG. Note that the processing including each step in FIG. 4 can be performed by the control unit 301 executing the device control program 42 .

First, in step S<b>01 , the control unit 301 receives an instruction to select the surveying instrument 2 from the input unit 303 . The display unit 304 of this embodiment is provided on a touch panel integrally formed with the input unit 303 . Therefore, the operator selects the surveying device 2 by touching the content displayed on the display unit 304 of the equipment control device 3, for example.

FIG. 5 is an example of a device setting screen 51 displayed on the display unit 304 in step S01. Items displayed on the device setting screen 51 include “brand”, which is manufacturer information of a device (instrument) such as the surveying device 2 , and “model name”, which is device identification information of the surveying device 2 . In addition, a communication connection method (for example, Bluetooth (registered trademark)) is displayed in “connection” on the device setting screen 51 . The device control device 3 receives a standby signal including device identification information from the surveying device 2 placed in the surrounding area, and the control unit 301 receives one or a plurality of standby signals acquired via the communication unit 302 to determine the surrounding area. can be detected. When the “model name” is selected, the control unit 301 displays on the display unit 304 the device identification information of the surveying instruments 2 included in the standby signals received from one or a plurality of surveying instruments 2 (for example, in a list format). displayed by). Therefore, the operator can arbitrarily select a device to be controlled from the group of surveying instruments 2 detected via the communication units 302 and 201 by performing an input operation on the input unit 303 . When the input unit 303 receives an instruction to select the device identification information of the surveying device 2, the control unit 301 establishes a communication connection with the surveying device 2 corresponding to the selected device identification information.

In this embodiment, an example in which any one is selected from the group of surveying instruments 2 detected via the communication units 302 and 201 will be described, but a plurality of surveying instruments 2 may be selected. In this case, the operator can use the input unit 303 to select which surveying device 2 to use when issuing a measurement instruction in step S04, which will be described later.

In step S<b>02 , the control unit 301 refers to the correspondence table 41 and obtains the grade information 412 corresponding to the device identification information 411 for the grade information of the surveying instrument 2 connected for communication. The control unit 301 sets the measurable distance, which is the operable range of the surveying instrument 2, according to the obtained grade information 412. FIG. For example, if the grade is "class 2", the measurable distance is set to "within 150m", and if the grade is "class 3", the measurable distance is set to "within 100m". Therefore, the control unit 301 can limit the measurable distance from the instrument point of the surveying instrument 2 to the measuring point 7, which is the object of measurement, according to the grade information.

Whether or not to restrict the operation by the measurable distance (operable range) depends on the operation mode of the surveying instrument 2 (equipment) (for example, when measuring a specific survey point 7, whether or not it is within the operable range). determination, etc.). Also, the measurable distance (operable range) corresponding to the grade information can be stored in the storage unit 305 in advance as an operating range setting table (not shown).

In step S03, the surveying device 2 is installed. The control unit 301 accepts selection of an instrument installation method from settings such as a resection method (for example, a posterior resection method) and a backsight point (known point) by an input operation to the input unit 303 . The control unit 301 transmits a control instruction to the surveying instrument 2 to specify the instrument point of the surveying instrument 2 by the selected instrument installation method. When the control unit 211 of the surveying instrument 2 obtains the instrument points by the instrument installation method selected by the instrument control device 3 , it transmits information on the instrument points to the instrument control device 3 . The control unit 301 acquires information on the instrument points of the surveying instrument 2 and stores it in the storage unit 305 .

In step S04, the control unit 301 instructs the surveying device 2 to measure. FIG. 6 is an example of the measurement instruction screen 52 displayed on the display unit 304 in step S04. The measurement instruction screen 52 includes the surveying device 2, the known points 6, the survey points 7, and various information and operation icons. Of these, the measurement points 7 to be measured (targets) can be data included in the measurement point data (for example, route data) read in advance by the device control device 3 from the storage unit 305 or the like. Station data may include one or more stations 7 . FIG. 6 shows an example in which one measuring point 7 is displayed. The control unit 301 receives an instruction to select the measuring point 7 displayed on the measurement instruction screen 52 through the input unit 303 .

The identification information of the selected measuring point 7 is displayed as the "name of measuring point" on the measurement instruction screen 52 (specific display is omitted). Also, in the "cross section", the cross section of the survey point 7 selected by the "station name" (for example, in the case of the survey point 7 in the route data, the pile number corresponding to the number pile number and plus position information) are displayed, and the crossing point of the survey point 7 selected by the "station name" is displayed in "crossing point". In addition, "from cross section" displays the distance from the cross section to which survey point 7 belongs to the actual measurement point in the front-back direction (route direction), and "from CL" displays the distance to the left and right from the center of the route to which survey point 7 belongs. A remote position is displayed.

After that, when the operator selects the measurement icon 521 (here, distance measurement icon) on the measurement instruction screen 52, the control section 301 performs the process of step S05.

In step S05, the control unit 301 determines whether or not the selected survey point 7 exceeds the distance limit set in step S02 (i.e., the distance L from the surveying instrument 2 to the survey point 7 is greater than the measurable distance). long or not). The control unit 301 performs the process of step S06 when the determination of step S05 is true (Yes), and performs the process of step S07 when the determination of step S05 is false (No).

In step S06, the control unit 301 transmits a measurement instruction to the surveying device 2 via the communication units 302 and 201, and causes the surveying device 2 to measure the survey point 7 (distance measurement or angle measurement). The control unit 301 can receive measurement results such as distance or angle via the communication units 302 and 201 and store them in the storage unit 305 .

On the other hand, in step S07, the control unit 301 does not transmit the measurement instruction to the surveying instrument 2, and displays on the display unit 304 that the survey point 7 that cannot be measured is selected. For example, the control unit 301 can cause the display unit 304 to display an error message "this point cannot be saved because the distance from the instrument point exceeds the limit".

Note that regardless of the contents of the error message, the control unit 301 may prohibit the measurement (distance measurement or angle measurement) itself, or perform the measurement, display the result on the display unit 304, and store the measurement data. may be processed to prohibit

In this way, when the input unit 303 receives an input of a measurement instruction to the surveying device 2, the control unit 301 determines that if the distance L from the surveying device 2 to the survey point 7 is longer than the measurable distance, the surveying device 2 It is possible to restrict acceptance of measurement instructions for For example, in the control cross-section workmanship observation, a limit is set in advance for the distance measurement value according to the surveying device 2 used for measurement (observation). The determination process in step S05 can prevent the surveying instrument 2 from performing measurements exceeding the limits.

(Modification)
Next, a modified example of this embodiment will be described. In this modified example, a correspondence table 41A shown in FIG. 7 is used instead of the correspondence table 41 shown in FIG. 3 in a configuration similar to that of the surveying system 1 described so far. Correspondence table 41A stores manufacturer information 413 and country information 414 in correspondence with equipment identification information 411 and grade information 412 .

A processing example using the correspondence table 41A will be described. In step S<b>01 of the control flowchart described with reference to FIG. 6 , the control unit 301 receives an instruction to select the surveying device 2 through the input unit 303 . The control unit 301 displays one or a plurality of brands (manufacturers) when "brand" is selected by an input operation on the input unit 303, and receives a brand selection instruction to select one or a plurality of them. . Further, when the "model name" is selected by the input operation of the input unit 303, the control unit 301 selects the equipment of the surveying instrument 2 included in the brand name selected by the brand selection instruction and detected by the aforementioned standby signal. Display one or more identification information. When the control unit 301 receives an instruction to select equipment identification information to be controlled from the group of surveying instruments 2 detected by the input unit 303 via the communication units 302 and 201, the control unit 301 receives the surveying equipment corresponding to the selected equipment identification information. A communication connection is made with the device 2 .

Therefore, the operator can easily select the surveying device 2 that he or she wants to use from among the plurality of surveying devices 2 .

6, the control unit 301 refers to the correspondence table 41A and refers to the surveying instrument 2 connected for communication. Information 412 is acquired and sought. That is, the control unit 301 obtains the grade information 412 corresponding to the combination of the device identification information 411 and the country information 414 . It should be noted that the selection instruction of the country information 414 may be configured such that the input unit 303 receives the selection at any time in step S02, or the country information 414 may be stored in the storage unit 305 in advance. The control unit 301 sets the measurable distance, which is the operable range of the surveying instrument 2, according to the obtained grade information 412. FIG. Therefore, the control unit 301 can limit the measurable distance from the instrument point of the surveying instrument 2 to the measuring point 7, which is the object of measurement, according to the grade information.

As described above, in this embodiment, the device control device 3 includes the storage unit 305 that stores the correspondence table 41 in which the device identification information 411 and the grade information 412 are associated, the input unit 303 that receives the device selection instruction, The communication unit 302 that communicates with the selected device and the grade information that corresponds to the device identification information of the device that is communicatively connected is obtained by referring to the correspondence tables 41 and 41A, and the device can operate according to the obtained grade information 412. The configuration including the control unit 301 that sets the range has been described. With this configuration, the grade of the equipment (for example, the surveying instrument 2) to be controlled by the equipment control device 3 is automatically set. And the device control program 42 can be configured.

In addition, the device control device 3 of the present embodiment prevents an operator from setting an erroneous grade, and prevents a measurement that exceeds the measurable distance limit determined according to the grade. can be Therefore, it is possible to improve the reliability of the measurement data measured by the surveying device 2 and the work efficiency.

Although the description of the embodiment of the present invention is finished above, the aspect of the present invention is not limited to this embodiment.

For example, in the above embodiment, the surveying device 2 was described as an example of a device that is connected for communication with the device control device 3, but instead of the surveying device 2, a GNSS (Global Navigation Satellite System) receiver, Other devices (herein including devices) such as rotating laser devices may be applied.

In addition, although FIG. 1 of the present embodiment shows a configuration in which the surveying device 2 and the device control device 3 are directly connected for communication, the surveying device 2 and the device control device 3 communicate via a relay device (not shown). It is good also as a structure which connects.

In addition, the grade information 412 is an arbitrary combination of, for example, "special", "1st grade", "2nd grade", "2nd grade A", "2nd grade B", or "3rd grade" according to the type of equipment. , and the operable range of the device may be set according to the performance of each grade.

Further, the device identification information displayed as options for the surveying apparatus 2 (device) on the device setting screen 51 is not limited to the "model name", and other identification information may be displayed in a selectable manner.

Further, the storage unit 305 may further store additional information of the surveying device 2 used for determining whether or not the equipment control device 3 permits connection (or permits control). The additional information may be, for example, presence/absence of "automatic tracking", version information, authentication information, or the like. In step S01 of the control flowchart of FIG. 4, the control unit 301 may prohibit connection with the surveying instrument 2 accepted by the selection instruction according to the content of the additional information. As a result, the device control program 42 can prohibit connection with the non-compliant surveying instrument 2 and can identify non-genuine surveying instruments. Further, when the control unit 301 determines that the surveying device 2 is not compatible, the control unit 301 may display an error message on the display unit 304 to the effect that the surveying device 2 to be determined is not supported.

If the device control program 42 does not support control of devices such as the surveying instrument 2, the control unit 301 may cause the display unit 304 to display a message prompting an update of the device control program 42. Updating the device control program 42 may include updating the correspondence tables 41 and 41A (for example, adding device identification information 411 and data corresponding to the device identification information 411).
