The data collector 3 instructs a distance measurement in accordance with a mode or a special mode for performing a measurement corresponding to a special survey for obtaining a displacement in the sky or a subsidence amount at the top (step 302).

As a result, the electronic device 9 controls the optical unit 8, and the distance measurement is performed. The distance measurement data obtained by the distance measurement is stored in a memory inside the electronic device 9, and is taken out from the data collector 3 according to an instruction (step 30).
3). Note that the above-described operation of FIG. 7 describes a series of operations related to distance measurement of the total station 2,
As in step 301, human actions are also included.

Next, the operation of the data collector 3 will be described in detail. In the data collector 3, as shown in FIG. 8, the main menu is displayed on the display unit 13 by the main processing so that the worker can visually recognize the work item (step 501).
Note that the main processing includes items of processing related to normal surveying, but the description is omitted in this embodiment.

The operator selects various works from the work items displayed on the display 13. At the time of surveying, two modes, a general mode for performing a general survey and a special mode for performing a special survey, are displayed so as to be selectable. Therefore, when the general mode is selected by operating the keyboard unit 11, the general survey is performed thereafter, and when the special mode is selected, the special survey is performed thereafter (steps 502 to 504). This process returns to the main process again regardless of which survey is completed.

First, when the special survey of step 504 is performed, the measurement of the displacement of the inner space of the tunnel and the amount of settlement of the crown are performed. In this case, as shown in FIG. 9, the data collector 3 is operated to operate the data collector 3 and the distance measurement / angle measurement instruction processing is selected from the main menu, similarly to the flow shown in FIG. (Step 700). In response to this, a distance measurement / angle measurement value transmission request is output to the total station 2 (step 710).

In the total station 2, as shown in FIG. 11, each measurement target section of a target (reflection sheet or corner cube) 30 to be measured in the tunnel by the optical section 8, for example, a first measurement target Part 3
1 is collimated. At this time, the housing body 7 is rotated, and the optical section 8 is tilted. When the electronic device 9 captures the data of the distance measurement and the angle measurement in this manner, the data is transmitted to the data collector 3 via the communication line 4 and is stored in the storage device 15 after performing a predetermined check. (Steps 711 to 713).

Note that the processing flow of steps 710 to 713 shows a flow of a series of processing for one surveying target unit, but receives distance measurement and angle measurement data of all the surveying target units (stored in the storage device 15). And then step 7
The check after step 12 and the final storage after step 713 may be performed.

When the distance measurement and angle measurement data have been obtained in this manner, the display on the display 13 returns to the main menu again. Then, the operator selects the inner sky displacement calculation process (including the calculation of the amount of settlement of the top end) from the main menu (step 700).

Since the distance measurement and angle measurement data have already been acquired in this inner space displacement calculation processing, the processing location and time are free. Coordinate conversion is performed based on the distance measurement and angle measurement data stored in the storage device 15 (step 72).
0), edge length calculation (step 721) is performed. As a result, as shown in FIG.
5, the respective side lengths a, b, c, d, e, and f are obtained. Based on these calculation results, the amount of displacement in the sky and the amount of depression of the top are further calculated, and the results of these calculations are stored in the storage device 15 as survey results (step 722).

When the data collector 3 is operated and a printer print instruction is designated, the survey results indicating the inner space displacement and the amount of depression of the top stored in the storage device 15 are read out and the printer device 14 is read out. Is forwarded to Printer device 15
Then, the measurement list 36 based on the survey result is printed out (step 730).

When the data collector 3 is connected to an external device (not shown) such as a personal computer via an interface cable, when the transfer instruction to the external device is specified, The survey result, distance measurement, and angle measurement data stored in the storage device 15 are transferred to an external device or the like (step 740). In the transfer destination external device, based on the received data, an analysis program stored in a storage medium 37 such as a magnetic tape, a magnetic disk, or a magneto-optical disk or set in advance for further processing. The analysis process is executed based on the above.

When the general survey of step 503 (FIG. 8) is performed, as shown in FIG. 10, after the tripod 5 is erected at a location corresponding to the survey object, the flow shown in FIG. Similarly, the data collector 3 is operated, and the distance measurement / angle measurement instruction processing is selected from the main menu.

The housing body 7 is rotated by the optical section 8 so that the measurement target section of the box scale to be measured, for example, the measurement target section 21 of the box scale 20 at the point A can be collimated. When the optical unit 8 is tilted, the angle measurement data and the distance measurement data at this time are taken into the electronic device 9 and stored. In accordance with the distance measurement / angle measurement value transmission request from the data selector 3, the angle measurement data and the survey data stored in the electronic device 9 are transmitted to the data collector 3 via the communication line 4, and a predetermined check is performed. Is made. Thereafter, the oblique distance, the horizontal distance, and the specific height difference are calculated and stored in the storage device 15.

Similarly, the measuring section 23 of the box ruler 22 at the point B and the measuring section 25 of the box ruler 24 at the point C are sequentially measured by the total station 2, and this is measured by the electronic device 9. While the data of the time is taken in,
In accordance with the distance measurement / angle measurement value transmission request from the data selector 3, the angle measurement data and the survey data stored in the electronic device 9 are transmitted to the data collector 3 and checked. Thereafter, the oblique distance, the horizontal distance, and the specific height difference are calculated and stored in the storage device 15.

As described above, according to the present embodiment, distance measurement and angle measurement are performed on the target portion to be surveyed by the total station 2 to obtain distance measurement data and angle measurement data. The distance measurement data and the angle measurement data obtained by the total station 2 are received via the communication line 4, and data processing based on the distance measurement data and the angle measurement data can be executed.

At the time of surveying, a mode relating to surveying is instructed to the total station 2 by an instruction of the data collector 3. The general mode is instructed when performing the measurement corresponding to the general survey, and the special mode is instructed when performing the measurement corresponding to the special survey for obtaining the inner space displacement and the amount of depression of the crown.

In the data collector 3, after the measurement according to the designated mode is performed, the distance measurement data and the angle measurement data, which are the measurement results, are received from the total station 2. Then, data processing according to the instructed mode is performed according to the operation of the keyboard unit 11, and a survey result is obtained by calculation. Therefore, the total station used for general surveying and special surveying for determining the amount of in-air displacement and the amount of settlement on the top is reduced by reducing the number of parts by using a common total station.
The total cost can be greatly reduced, and the versatility of the system can be greatly increased.

As for, the operability corresponding to the conventional survey measurement has been realized, so that anyone can easily use it. In addition, the optical unit 8 of the total station 2 performs distance measurement by light waves using a target arranged in a target unit to be measured. In the optical unit 8, since the optical paths of the emitted light beam and the received light beam are independent,
The emitted light beam is prevented from being received as it is without passing through the target, and a large amount of light beam reflected from the target is received. Therefore, high-precision surveying can be realized in both general surveying and special surveying.

Further, the distance measurement data and the angle measurement data received from the measuring device are stored in the storage device 15 of the data collector 3 and the measurement results obtained by the data processing are also stored in the storage device 15. The distance measurement data, the angle measurement data, and the measurement result stored in the storage device 15 are stored. Therefore, after surveying, by moving the location or shifting the time, by connecting the interface cable to another external device and transferring the data, it is possible to carry out processing such as analysis and drawing. This data can be applied to processing (work) such as management of public works, registration, and civil engineering work.

In the above-described embodiment, the two modes of the general survey and the special survey have been described as the modes. However, the accuracy of the angle measurement and the distance measurement is further divided stepwise according to the survey target. Thus, a survey result according to the work request may be obtained. In the above-described embodiment,
Although a wired communication line 4 is connected between the total station 2 and the data collector 3 as shown in FIG. 2, the present invention is not limited to this, and wireless communication of data and control signals is performed. May be performed. In this case, it is not necessary to secure the space of the communication line 4 and it is not necessary to worry about the disconnection of the communication line 4 during the work.

Further, in the above-described embodiment, as shown in FIG. 2, the wired communication line 4 is connected between the total station 2 and the data collector 3, but the present invention is not limited to this. Instead, the electrical connection between the total station 2 and the data collector 3 may be a coupling mechanism using a connector. In this case, the data collector 3 becomes a part of the total station 2 and the data collector 3 is fixed. In this case, it is not necessary to secure a space for the communication line 4 and the communication line 4 is disconnected during the operation. You don't have to worry about
