[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying apparatus using a global positioning system, and more particularly to a surveying apparatus which can be used together with a total station.

[0002]

2. Description of the Related Art Conventionally, this type of surveying apparatus is described in, for example, the following two publications. JP, 4-151509, A JP, 4-151510, A The main composition of the above-mentioned conventional surveying device is shown in Drawing 13.

[0003] A conventional surveying device is composed of the following three devices. The first is the total station 200. Second, a plurality of GPS surveying instruments 210 using the global positioning system, for example, one reference station side and one measurement station side GPS survey instrument 210,
220. The third is a personal computer 230, which measures the GPS measured by the GPS surveying instruments 210 and 220, respectively.
The measurement value and the total station measurement value measured by the total station 200 are input to the personal computer 230 and converted into a single coordinate system using the coordinate conversion program.

[0004]

However, the conventional surveying instrument described above has the following three problems. First,
Since the personal computer 230 was installed in the office, there was the first problem that the quality of the measurement result could not be judged at the surveying site. That is, as a result of returning to the office and judging the quality of the measurement result, for example, when the quality is poor, there is a case where the person is forced to visit the site again and perform a remeasurement.

Second, it is possible to bring a small portable personal computer 230 to the survey site.
There was a second problem that the number of items brought in increased. Further, even if the small portable personal computer 230 is brought to the site, it is necessary to sequentially input the GPS measurement value and the total station measurement value to the personal computer 230 in order to judge the quality of the measurement result. Inefficient.

Thirdly, the total station 200 has
There is a third problem in that the reference coordinate value and the absolute azimuth must be input. Therefore, the invention according to claim 1 is made in view of the first and second problems of the above-described conventional technique, and the purpose thereof is the following two points.

First, the object of the invention as claimed in claim 1 is that not only can the measurement result be immediately known at the surveying site and the measurement result can be immediately utilized, but also the quality of the measurement result can be judged at the surveying site. The point is that I was able to do it. Secondly, the object of the invention as set forth in claim 1 is that it is possible to save the labor of inputting data at the surveying site without increasing the number of equipments brought to the surveying site.

The invention according to claim 2 is the above-mentioned claim 1.
The present invention has been made in view of the above-mentioned third problem of the conventional technique in addition to the above-mentioned object of the invention, and the object thereof is the following two points. Firstly, the object of the invention as set forth in claim 2 is to enable the total station and the GPS surveying instrument to be connected to each other, so that the measurement result of the GPS surveying instrument can be used for inputting the reference coordinate values of the total station and the absolute azimuth. The point is that you can use.

Secondly, the object of the invention according to claim 2 is G
The point is that the GPS survey instrument can be used independently by removing the PS survey instrument from the total station. The invention according to claim 3 has the following object in addition to the object of the invention according to claim 1 or claim 2 described above. That is, an object of the invention of claim 3 is to make it possible to reduce the size and cost of the system on the GPS survey instrument side by performing coordinate conversion on the total station side.

The invention according to claim 4 is the above-mentioned claim 1.
Alternatively, in addition to the object of the invention as set forth in claim 2, the following objects are provided. That is, the object of the invention described in claim 4 is to omit the coordinate conversion on the side of the total station, and contrary to the invention described in claim 3, the system on the side of the total station can be downsized and the cost can be reduced. There is a point in doing so.

The invention according to claim 5 is the above-mentioned claim 1.
In addition to the objects of the inventions described in 4 to 4, the following objects are intended. That is, an object of the invention of claim 5 is to enable mutual data to be used in real time by performing digital data communication between the total station and the GPS surveying instrument.

The invention according to claim 6 is the above-mentioned claim 5.
In addition to the objects of the described invention, the following objects are intended. That is, the object of the invention of claim 6 is to use an optical communication cable for digital data communication so that not only can a large amount of data be communicated quickly but also the occurrence of radio interference can be prevented. There is a point in doing so.

This is a system in which the GPS surveying instrument itself receives a weak radio wave from the satellite, and therefore has a problem of being vulnerable to noise. On the other hand, by using the optical communication cable, the generation of noise can be suppressed, and the cable itself can be prevented from being affected by radio waves, thus preventing radio wave interference. The invention according to claim 7 has the following object in addition to the object of the invention according to claim 5 described above.

That is, the object of the invention of claim 7 is to:
The use of wireless communication for digital data communication eliminates the need for cables, so that not only can the number of equipment to be brought in be reduced, but also cables need not be connected and there is no need to worry about disconnection. The invention according to claim 8 is
In addition to the objects of the invention described in claims 1 to 7, the following objects are intended.

That is, the object of the invention of claim 8 is to:
By sharing the power supply unit between the total station and the GPS surveying instrument, storage management and charging management of the power supply unit can be facilitated. Conventionally, the total station and the GPS surveying instrument were each provided with separate power supply units.

For this reason, it is easier to store and charge the power supply units if the capacities and sizes of both power supply units are unified. However, since the total station and the GPS surveying instrument have different sizes and power consumptions, a design change is unavoidable if the power sources of both are unified.

Therefore, by sharing the power supply units of both as a single supply source without unifying the power supply units of both, it is possible to facilitate storage management and charge management of the power supply units. It was done like this. The invention of claim 9 is in addition to the object of the invention of claims 1 to 8 described above,
It aims at the following points.

That is, the object of the invention of claim 9 is to:
The point is that even the GPS surveying instrument on the measuring station side can see the combined coordinate values with the total station. This is because, for example, in the case of measuring, setting a stake on a predetermined coordinate, or the like, the own coordinate is required in real time.

For example, the GPS coordinate values (dx, dy, d
z) and the variance λ are calculated.

After the above baseline analysis processing, as shown in FIG.
Proceeding to the next sixth step S60, the solution (dx, dy, dz, λ) obtained by the baseline analysis processing is stored in a memory (not shown) in the GPS main body 41 of the reference station-side GPS surveying instrument 40. Next, as shown in FIG. 6, a seventh step S70
