Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying instrument having a resuming function in which a program can be selected in a hierarchical menu and the program can be shifted to a program at the end of the previous survey when resuming the survey.

[0002]

2. Description of the Related Art Since a surveying instrument such as a total station has a plurality of functions such as an observation function for measuring a distance and an angle, and a data management function, its program becomes huge, and each function can be selected by a multi-level menu. Configuration. In a program having such a configuration, for example, when the power of the surveying instrument is turned on, a main menu is displayed on the display, and when one of the main menus is selected, a sub-menu such as a ranging or a condition setting in a lower hierarchy is selected. Is displayed. The operator selects, for example, a program for distance measurement or the like from the submenu, and places the surveying instrument under control of a program for executing a function such as distance measurement.

Therefore, when the same survey is repeatedly performed, it is necessary to follow the hierarchical menu every time the surveying instrument is started, and the operation from the start of the surveying instrument to the start of the survey is complicated. Therefore, the conventional surveying instrument has added a resume function that can resume from the state at the time of surveying the previous day, so that after starting, it can automatically transition to the state of the program used at the end of the previous survey, and started The need for complicated settings from the start to the start of surveying has been eliminated, and surveying work has been streamlined.

[0004] On the other hand, when a specific function is executed by the surveying instrument, a constant or condition for executing the function may be required. For example, distance measurement measures the phase difference between the light projected toward the target and the light reflected and received by the target,
The distance to the target is obtained from the phase difference and the speed of light. The calculation of this distance requires a value of the speed of light.
It changes depending on the atmospheric pressure and the like. Therefore, in order to obtain an accurate speed of light, values of the temperature and the atmospheric pressure at the survey site are required.

Further, a surveying instrument having a communication function can output measured data to an external device such as a computer. In this case, the communication speed such as the baud rate of the surveying instrument must be adjusted to the communication speed of the external device, and the communication speed needs to be set by the condition setting function of the surveying instrument.

FIG. 8 is a schematic operation flowchart of a conventional surveying instrument. The flow of the surveying work will be described according to this flowchart. When the power of the surveying instrument is turned on in step 50, the display becomes a startup screen, and a message "Please shake the telescope" is displayed (step 51). The operation of shaking the telescope is an operation for resetting the encoder for measuring the altitude angle and adjusting the zero point to a horizontal state, and is always performed before starting the survey.

When the telescope is shaken in step 52, the encoder for measuring the altitude angle is reset in step 53, and in step 54, it is determined whether or not the resume function is on. If the resume function is on, resume processing is performed in step 55, and the program shifts to the state of the program used at the end of the previous survey (step 6).
1).

On the other hand, if the resume function is off, the process proceeds from step 54 to step 56, and the main menu is displayed. The main menu includes menus for setting conditions, basic observations, and the like. For example, when a menu for setting conditions is selected, the screen shifts to a constant display screen of step 57 below the menu.

The constant display screen in step 57 is a screen for displaying constants such as temperature, pressure, baud rate and the like to be set. In order to set constants and the like, select an item to be set on the constant display screen in step 57, and further select step 5 in the lower layer.
Set each constant on the constant setting screen 8. When the constant setting is completed, the display returns to the main menu and selects the next menu.

When basic observation is selected in the main menu of step 56, a submenu of basic observation is displayed in step 59. When an observation program is selected in the basic observation submenu, distance measurement or the like is performed in step 60 of the lower screen, and the measurement data is displayed on the display.

The recording of the measurement data is performed in step 60.
The measurement is performed on a data recording screen or the like below the observation screen, and when the measurement data is recorded, the surveying is often ended. For this reason, the lower screen of the observation screen in step 60 is defined as step 61, and the program at the end of the previous time is displayed for convenience. As described above, if the resume function is on, the current survey is started from the hierarchical screen of step 61, and the trouble of following the hierarchical menu from the main menu (step 56) can be omitted.

On the other hand, when resetting the constants and the like used in the program in step 61, the process returns to the main menu in step 56, shifts from the main menu to the constant setting screen in step 58, and resets each constant. .

[0013]

A surveying instrument having such a resume function returns to the state of the program used at the end of the previous survey when the resume function operates after the start-up. Is repeated, it is not necessary to follow the hierarchical menu every time.

However, some of the constants, for example, constants such as temperature and atmospheric pressure, change in a short period of time, and therefore need to be reset frequently. In this case, when the resume function operates and returns to the program used at the end of the previous survey, to set the constants, return to the main menu from that program, switch to the constant setting screen from the main menu, and Setting constants required a lot of trouble.

Therefore, the present invention provides a surveying instrument which can easily reset the constants or conditions which need to be frequently reset on the initial screen while maintaining the simplicity of the operation by the resume function. Aim.

[0016]

The object of the present invention is to provide a surveying system in which a startup screen is displayed when the power is turned on, and after performing a predetermined initial operation on the telescope, the resume function shifts to a state at the end of the previous surveying. The present invention is attained by providing a surveying instrument wherein a predetermined constant required for surveying can be set before performing an initial operation on the telescope on the startup screen.

According to the present invention, a constant which needs to be frequently reset before the resume function is activated can be set on the start screen displayed first after the start, so that the surveying instrument having the resume function can be set. In this case, it is possible to save the trouble of returning to the main menu from the program used at the end of the previous survey and further moving to the constant setting screen to reset the constants.

Further, the predetermined constant set at the end of the previous survey is displayed on the start screen of the surveying instrument of the present invention.

According to the present invention, the constant set at the end of the previous survey is displayed on the start-up screen, so that it is possible to judge the necessity of changing the constant, and the constant changing process can be efficiently performed. It can be carried out.

Further, the initial operation of the surveying instrument of the present invention is as follows:
The telescope is characterized in that the telescope is passed through a horizontal plane and shaken.

The initial operation of shaking the telescope is always the first operation due to the nature of the surveying instrument in order to reset the encoder inside the surveying instrument. Therefore, the resume function operates after this initial operation. According to the present invention, the constant can be set before the operation of shaking the telescope which is the trigger of the resume function, so that the necessary constant can be changed without changing the operability of the conventional surveying instrument. Become.
In addition, if there is no need for resetting, the measurement can be started by shaking the telescope as in the related art, so that the smoothness of the conventional surveying work is not hindered.

Further, the constant of the surveying instrument of the present invention includes at least one of the temperature, the atmospheric pressure, and the prism constant, and the predetermined constant is set in a condition setting menu below the main menu which can be shifted after the initial operation. And other constants can be set.

According to the present invention, since constants that need to be frequently reset to affect measurement accuracy can be reset on the startup screen, the constants can be set without hindering the efficiency of the surveying operation by the resume function. Resetting can be performed easily.
