DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction management system for constructing a landfill offshore or opening a mountainous area to build a residential area.

[0002]

2. Description of the Related Art When an artificial island is constructed on the sea, landfilling is performed over a wide area using a large number of bulldozers. Needless to say, it is necessary to level the top of the ground to be made as planned.

[0003] When the bulldozer is used to construct the ground, the management of whether the top of the ground to be constructed is at the planned height is performed by first conducting a preliminary survey to measure the difference from the planned height. Next, a procedure called staking is installed everywhere so that the difference can be understood, then the operator visually observes the goal, level the top, and finally repeat the survey for confirmation. General.

[0004]

However, such a work is extremely complicated, and the problem is that as the work area becomes wider, an enormous amount of time and labor are required.

The present invention has been made in view of the above circumstances, and has as its object to provide a construction management system capable of efficiently and accurately managing the top of a ground surface to be constructed. .

[0006]

According to a first aspect of the present invention, a construction management system according to the present invention includes: a GPS surveying device mounted on a construction moving body; Arithmetic processing means for calculating the height of the ground surface immediately below the construction moving body as the actual ground height together with its plane position using survey data from the GPS surveying device mounted on the body, and storing the design ground height And a display means for displaying the calculated actual ground height together with the designed ground height at the same plane position.

[0007] The creation management system according to the present invention comprises:
Posture measuring means for measuring the posture of the creation moving body, the posture of the creation moving body measured by the posture measuring means is displayed on the display means, and the actual ground height and the design The arithmetic processing means is configured so that the ground height is displayed in a plane or three-dimensionally.

[0008] In addition, the creation management system according to the present invention,
The arithmetic processing means is configured such that a difference between the actual ground height and the design ground height is displayed in different colors according to its sign and magnitude.

[0009] The creation management system according to the present invention includes:
The arithmetic processing means is configured such that a work purpose is displayed on the display means in accordance with the sign of the difference between the actual ground height and the design ground height.

[0010] The creation management system according to the present invention includes:
It is provided with posture measuring means for measuring the posture of the creation moving body, the actual ground height and the design ground height are displayed in a cross-section along a traveling direction or a desired azimuth of the creation moving body. This constitutes arithmetic processing means.

In the construction management system according to the present invention, when the construction is performed while moving a construction moving body such as a bulldozer, a GPS surveying device mounted on the construction moving body is used to directly below the construction moving body. The height of the ground surface is calculated by the processing means together with the plane position as the actual ground height. That is, the position of the construction moving body is measured by the GPS surveying device, and the measured position is measured on the ground surface by using a relative positional relationship between the measurement location and a place where the construction moving body is in contact with the ground surface. , And this is taken as the height of the ground surface and its planar position.

Next, the designed ground height at the same plane position as the ground surface is read from the storage means, the designed ground height is displayed on the display means together with the actual ground height, and the calculated actual ground height is calculated. It is written and stored in the storage means as needed.

[0013] In this case, the actual ground height at the current position of the creation moving body is displayed on the display means together with the design ground height at the plane position.

For this reason, as in the prior art, first, a pre-survey is performed to measure the difference from the planned height, then targets are set everywhere so that the difference can be seen, and then the targets are visually observed by the operator. It is possible to easily manage the height of the ground under construction without performing the cumbersome work procedure of leveling the top while performing surveying for confirmation again at the end.

[0015] The positioning method of the GPS surveying device is optional, but in terms of accuracy and real-time performance, it is preferable to use the DGPS method, which is a relative positioning method, rather than the single positioning method. It is desirable to use an RTK-GPS (real-time kinematic GPS) system, which is a type of interference positioning system.

When the RTK-GPS method is adopted, a fixed station having a known coordinate position is additionally required in addition to the GPS surveying device mounted on the construction mobile, and the RTK from the fixed station is required. It goes without saying that it is necessary to mount a wireless device for receiving the correction data on the construction moving object. In the case of such a positioning method, the RTK correction data from the fixed station is received by the radio of the construction mobile as the mobile station, and this is combined with the GPS signal received by the GPS surveying device of the construction mobile. As a result, the position of the construction moving object is calculated and output as survey data.

The arithmetic processing means, the storage means, and the display means may be configured in any manner, but may be formed using various computers such as a desktop personal computer, a notebook personal computer, a pen-compatible mobile personal computer, and a portable information terminal. A hard disk or a liquid crystal display built in or external to the computer can be used as the storage means and the display means, respectively.

The design ground height and the actual ground height may be stored in advance as a function of the plane position, or may be stored at any time.

How the actual ground height is displayed together with the designed ground height at the same plane position on the display means is arbitrary. For example, the actual ground height and the designed ground height are adjusted in accordance with the movement of the construction moving body. It is also conceivable to display in real time numerically the attitude of the creation moving body, and the attitude of the creation moving body measured by the attitude measurement means is displayed on the display means. In the case where the arithmetic processing means is configured so that the actual ground height and the designed ground height are displayed on a plane or in a three-dimensional manner, the actual ground height and the designed ground height It is displayed not only at the current position of the body but also within a predetermined range including the surrounding area, so that the progress status of the crown level, that is, the range where the work has been completed and the range where the work should be performed, can be grasped at a glance It is Rukoto, even if it is sufficient to travel Construction for mobile in either direction in performing work can easily grasp.

The posture of the construction moving body is displayed on the display means using a geometric figure such as a triangle or an arrow or a simplified plane figure of the construction moving body so that its orientation can be recognized. It is possible.

The attitude measuring means can be constituted by, for example, a mechanical gyrocompass, an optical gyrocompass, an electro-magnetic compass, or the like. In displaying the designed ground height and the actual ground height, it is conceivable to use a plane element of, for example, 50 cm square as one unit. Further, as for displaying them, they may be displayed as a plan view or three-dimensionally as in a bird's-eye view.

Here, how the actual ground height and the designed ground height are displayed in a plane or in a three-dimensional manner is arbitrary. For example, a plane element of 50 cm square as described above is displayed on a display means, and It is conceivable that the actual ground height and the designed ground height are numerically displayed in two steps in each element, but the difference between the actual ground height and the designed ground height is color-coded according to its sign and size. When the arithmetic processing means is configured as described above, the work purpose such as whether to cut or fill and the amount of work such as the height to cut and the height to fill can be grasped at a glance. Work becomes easier.

Further, in the case where the arithmetic processing means is configured so that the work purpose is displayed on the display means in accordance with the sign of the difference between the actual ground height and the design ground height, the cut should be made. Regarding the purpose of work, such as whether or not to embank, work can be carried out without any hesitation, and there is no fear that the work will be performed in reverse by mistake.

On the other hand, there is provided attitude measuring means for measuring the attitude of the construction moving body, and the actual ground height and the design ground height are displayed in a cross-section along a traveling direction or a desired direction of the construction moving body. In the case where the arithmetic processing means is configured so as to be performed, it is possible to intuitively grasp the progress status of the crown leveling.
