The measuring system in the measuring work of the conventional steel frame erection work using this measuring device must operate the measuring instrument 1 directly on site while interacting with the measuring personal computer 4. , It was troublesome in that respect.

An object of the present invention is to solve the above-mentioned problems of the conventional example, to significantly reduce the on-site surveying work, to save the labor of the surveying work, and to improve the accuracy of completion. To provide.

[0007]

In order to achieve the above-mentioned object, the present invention provides a combination of a measuring instrument and a measuring personal computer for controlling the measuring instrument, and a single measuring instrument can be used for vertical angle, horizontal angle and distance. Elements can be measured at the same time, processing from data calculation to recording is performed with a measuring PC, and the measuring instrument has an automatic collimation function that automatically searches for a light receiving device within a certain range and finds its center. The measuring device is used, and the measuring points by the light receiver are indicated on the steel frame drawing using the CAD placed in the office. The measuring work is automatically performed by the measuring device of the measuring device and placed in the office. Check the construction status by drawing a drawing with the coordinates actually measured on the original steel frame drawing by CAD, and check the measurement PC connected to the measuring instrument of the measuring device from the office PC. Through the line Septum is intended to be required to operate.

[0008]

According to the present invention as set forth in claim 1, it is possible to improve the erection accuracy at the time of erection of the steel frame, check the positional deviation of the steel frame by superimposing the design drawing and the actual measurement data, and give an accurate instruction to correct the distortion. Therefore, labor saving can be realized by instructing measurement points by using CAD and automatic measurement.

According to the second aspect of the present invention, in addition to the above-mentioned operation, measurement instructions and collected measurement data can be obtained from a personal computer of the office via a premises line while remotely operating. The construction status can be grasped by.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of an apparatus used in an automatic measurement system in steel frame construction of the present invention, and FIG. 2 is a flowchart showing an actual flow of automatic measurement in the automatic measurement system in steel frame construction of the present invention.

The structure of the measuring device will be described first. As in the case of FIG. 11, the measuring device 1 is a Leica total station TM-3000 (trade name "WI").
LD ”), and includes a power supply 2 as a control mechanism, a controller 3 that controls and operates the measuring instrument 1 via the power supply 2, and a measuring personal computer 4.

In this way, the measuring device can simultaneously measure the three elements of vertical angle, horizontal angle, and distance with one measuring instrument 1, and in combination with the measuring personal computer 4, from calculation of data to recording. It has a comprehensive function and automatically searches for a light receiver as measuring point 5 (see Fig. 11) within a certain range.
It has an automatic collimation function to find its center.

Reference numeral 7 in the figure denotes a CAD placed in an office, which is operated by a personal computer 9 (for example, a product name PC98 of NEC Corporation).
Use AUTOCAD. 8 is a DXF file, and the steel frame drawing must be created by CAD7, and the DXF file 8 receives it.

Further, the measuring personal computer 4 placed on the site of the measuring device and the office personal computer 9 are connected to each other through a premises line 10, and the measuring personal computer 4 is connected to the office personal computer 9 through the premises line 10. I decided to operate it remotely. In the figure, 11 is a modem connected to the measurement personal computer 4, and 12 is a modem connected to the office personal computer 9.

As described above, the measurement of the measuring device 1 is performed by providing the measuring point 5 by the light receiver on the steel frame and the reference point 6 by the light receiver as in the case shown in FIG. However, this light receiver may use a reflection sheet instead of using a prism.

As shown in FIG. 2, CAD 7 is used to write the position of the measuring point on the steel frame drawing, and this is read into the DXF file 8.

The steel frame drawing in which the positions of the measurement points are written is given to the steel company, and the steel company makes a steel frame and marks it at the position specified in the drawing.

The inked steel frame is carried into the site, a light receiver is installed at the inked position (measurement point), and the measuring instrument 1 is installed at the designated position after lifting and assembling the steel frame.

On the other hand, the system flow of CAD7 is as shown in FIG.
Find a position where all the specified measuring points can be seen from measuring instrument 1. 5 and 6 show display screens when the CAD 7 checks the interference between the line of sight and the pillar or beam in such positioning.

A measurement instruction file is created by designating the measurement time and the like, and the measurement instruction data is received and confirmed at the site. Further, it is confirmed and corrected whether or not there is a light receiver as the measuring point 5 at the position of the measurement instruction data.

The measuring operation is automatically performed by the measuring device unattended during the night without vibration due to construction work. The flowchart of the automatic measurement concerning FIG. 4 is shown. The measuring personal computer 4 of the measuring device reads the measurement instruction file sent from the office, gives instructions to the measuring instrument 1 at a specified time, and calculates the three-dimensional coordinates from the measured vertical angle, horizontal angle, and distance. , Create a measurement result file (three-dimensional coordinates).

Further, the screen display of the measurement result is performed in real time on the display screen of the measurement personal computer 4 or the office personal computer 9.

Explaining the automatic collimation method at the time of the measurement, the measurement result file (three-dimensional coordinate) is created as described above. When the three-dimensional coordinate is given to the measuring personal computer 4, it is converted into a vertical angle and a horizontal angle, an instruction is given to the measuring instrument 1, and the main body goes to collimate the measuring point in that direction. At that time,
If there is no measurement point (light receiver) in the indicated direction, search for the range defined in the vertical and horizontal directions as shown in FIG. 9, widen the scan range to the third time, and if not found Ignores and goes to collimate the next station. Fig. 10 shows how to obtain the center coordinates when collimation is possible.

The construction result is checked by superimposing the drawing of the measured results on the original steel frame drawing by the measured coordinates. 7 and 8 show display screens in which the measurement results and the original steel frame drawings are superimposed.

In the above embodiment, the measurement work is automatically performed unattended during the night when there is no vibration due to construction, but it can also be performed in real time.

Further, although the measuring personal computer 4 placed at the site and the personal computer 9 at the office are connected by the premises line 10, it is also possible to connect the site and the office by changing the premises line 10 to wireless. .
