Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying system mainly used when surveying a large area.

[0002]

[Prior Art] When surveying in civil engineering construction work,
It is common for assistants and engineers to work in pairs. In other words, an assistant holds a box measure or target called staff at a surveying point, and an engineer collimates this to measure the position of the box scale or target with a surveying device such as a level or transit. While repeating the work of the assistant moving to the next surveying point and performing the measurement again, the prescribed surveying points are successively measured.

[0003]

However, in such a method, an assistant for surveying is always required,
The problem that one technician cannot do surveying,
Since it is necessary to instruct the assistant at the next surveying point using a transceiver or the like, there has been a problem that it is complicated and time-consuming.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a surveying system capable of performing measurement by an engineer alone.

[0005]

In order to achieve the above object, a surveying system according to the present invention, as set forth in claim 1, is an automatic tracking type distance measuring and angle measuring device and the automatic tracking type distance measuring and angle measuring device. A measuring-side transceiver connected to the instrument, an operating-side transceiver that transmits data between the measuring-side transceiver, and a portable computer connected to the operating-side transceiver. A storage means for storing the measurement data of the target position which is measured by the automatic tracking type distance measuring and angle measuring instrument and transmitted through the measurement side transceiver and the operation side transceiver, and the measurement data is used. A screen display unit for displaying the current position of the target and its movement locus is provided, and the portable computer is provided with an operation unit for giving an operation instruction to the automatic tracking type distance-measuring instrument. Of the stored known point, which is constituted of the operation means so as to perform an operation instruction to suited the automatic tracking type distance measuring angle measuring instrument into a desired known point selected.

[0006]

[0007]

Further, the surveying system according to the present invention is such that a desired surveying point is superimposed on the screen display means and displayed.

In the surveying system according to the present invention, an engineer carrying a portable computer causes the target to be tracked by an automatic tracking type distance measuring and angle measuring device while carrying the target. Then, the measurement data of the target position measured by the automatic tracking type distance measuring and angle measuring instrument is received by the portable computer via the measuring side transceiver and the operating side transceiver and stored in the storage means, and the received measurement is performed. The current position of the target and its movement trajectory are displayed on the screen display means using the data.

In this way, the surveying engineer
It is possible to grasp the survey results accurately and in real time while always checking where you are by looking at the screen display means, and the technician alone surveys without the need for an assistant as in the past. It can be performed.

The automatic tracking type distance measuring and angle measuring instrument includes an automatic tracking type total station and an automatic tracking type transit. In addition, the format of the portable computer is arbitrary and can be appropriately selected from a notebook computer, a pen input computer, a touch panel computer, and the like.

The moving locus of the target may be displayed as discontinuous data consisting only of the data of the actually measured points, or the coordinates of the unmeasured points may be the coordinate data of the known known points. It may be obtained by interpolation processing or the like and displayed as a continuous curve.

When measuring with the automatic tracking type distance measuring and angle measuring instrument, the measurement is automatically performed at every time interval set on the side of the instrument, and the measured data is transferred to the portable computer in the same manner. Although it may be automatically performed, if the portable computer is provided with an operating means for instructing an operation to the automatic tracking type distance measuring and angle measuring equipment, the operating means is operated to perform the automatic tracking type distance measuring By giving an operation instruction to the angle instrument, the technician can cause the automatic tracking type distance measuring and angle measuring instrument to measure the target position, transfer the measurement data, record the measurement data, etc. at a convenient timing.

In particular, even when the automatic tracking type distance measuring and angle measuring device loses sight of the target, that is, when mirror lost (prism lost) occurs, the automatic tracking type distance measuring and angle measuring device is shaken vertically and horizontally by remote operation. The target can be recaptured.

Here, among the known points stored in the storage means, the operating means is provided so that an operation instruction for directing the automatic tracking type distance measuring and angle measuring device to a selected desired known point can be given. With this configuration, even if a mirror-lost occurs in the automatic tracking type distance measuring and angle measuring device, the target is set at the selected known point and the automatic tracking type distance measuring and angle measuring device is directed to the known point in such a state. By making it possible, it is possible to surely recapture the target.

If the desired surveying point is displayed on the screen display means, the technician carrying out the survey with the target and the surveying point projected on the screen display means his own. While confirming the position, it is possible to reliably move to the next survey point.
