2. Description of the Related Art The position and direction of a construction machine can be obtained by measuring the coordinates of two points on the construction machine.
There are various methods for measuring the coordinates, and among them, the positioning technology using a GPS satellite, which has been popularized recently, has high accuracy, is easier to handle than conventional positioning, and is versatile. Is available and is the best. The coordinates of a construction machine are generally measured by using a pair of GPS antenna means and a reference station and a GPS satellite at a known position. However, on a construction machine, especially on a large work boat these days, a leader or a crane arm is used. A columnar structure with a complicated shape such as is installed, which acts as a radio wave obstruction, and two GPS antenna means are simultaneously installed on the satellite because of the relationship between the orientation of the work boat and the arrangement of the satellites in the positioning time zone. It may not be possible to capture the radio waves.

In the figure, a leader installed on the work boat 1 or a crane is shown. A highly rigid antenna strut (high structure) 5 is integrally erected in the vicinity of the stern of a work boat that is relatively unaffected by radio interference due to a high columnar structure such as an arm, and the top of this strut 5 is Is the GPS antenna installation position 3.

[0016] In civil engineering construction machines, since the work is installed on the surface of the earth or under the water surface, the coordinates are often under the construction machine. When positioning a construction machine, it is preferable to install an antenna in the lower part of the machine and obtain the coordinates in order to minimize the error due to the inclination of the machine in order to improve the accuracy. However, in the GPS positioning method, since radio waves from satellites are used for positioning, there is a risk that radio waves may be blocked by obstacles. In other words, there is a columnar structure with a complicated shape, such as a leader or a crane arm, installed on a recent work boat, which acts as a radio wave obstacle.
Since the GPS antenna may not be able to capture the radio waves of the satellite in relation to the arrangement of the satellites in that time zone, the GPS antenna should be as independent as possible from a place where the influence of the radio wave obstacle is not exerted, for example, an obstacle around it. Therefore, it is desirable to provide it at a relatively high position.

However, it is difficult to say that the apex of the high structure provided on the work boat is always kept in a fixed position by moving due to the inclination of the high motion of the boat, the work condition or the bending of the high structure due to the strong wind. . Therefore, the GPS antenna is mounted on a rigid high structure dedicated to make it easy to receive satellite radio waves in the positioning time zone, and the tilt angle of the high structure is calculated at the same time as the GPS coordinates and the machine (workboat ) By correcting the coordinates in the lower part, it is possible to prevent radio interference due to obstacles and improve the positioning accuracy of the coordinates.

(3) FIG. 3 shows a plan view of a main part of another embodiment of the construction machine positioning system using GPS and a gyro according to the present invention. In the figure, the work boat 1 is represented by a rectangular thin line and its center line 2 The intersections 4 and 8 with the rectangular sides respectively indicate the center points (center positions of the stern) of the line connecting the construction position of the workpiece on the work boat and the installation points of the pair of GPS antennas. The installation positions X 2 , Y 2 and X 3 , Y 3 of the pair of GPS antennas are symmetrical with respect to the central position 8 of the stern of the work boat 1 which is represented by a rectangular thin line. Normally, a pair of GPS antennas determine respective coordinates X 2 , Y 2 and X 3 , Y 3 , and if the coordinates of two points on the work boat are measured, the position and orientation of the work boat are also determined. Based on this, it is possible to determine the construction position 4 of the workpiece. At this time, the measurement of the azimuth angle by the gyro compass or the gyro assistance system becomes unnecessary.

However, when positioning of one GPS antenna becomes impossible due to the relationship between the position of the satellites in the positioning time zone and the position of the radio wave obstruction due to the orientation of the work boat, positioning of the other GPS antenna becomes impossible. When the position of the work boat (GPS antenna) is measured by a reference station and a GPS satellite at a known position to obtain, for example, X 2 and Y 2 , the coordinates of the work boat and the gyrocompass mounted on the work boat cause the work boat to move on the work boat. The workpiece construction position 4 can be specified by the same process as described in the above-described embodiment.

Further, the respective coordinates X 2 , Y 2 and X 3 , Y 3 are obtained by the pair of GPS antennas, and when the orientation (position) of the work boat is known, it is mounted on the work boat. If you use the existing gyro assistance system and measure the azimuth angle of the work boat at that time in advance, the coordinate position of one newly positioned antenna based on that azimuth angle and the assistance system Thus, it is possible to identify the new workpiece construction position 4 on the work boat by the same process as described above. However, unlike the gyro compass, the gyro assistance system
Since it is a means for specifying the relative orientation and errors accumulate over a long period of use, it is necessary to perform work properly.
It has the advantage of low equipment costs.

The above is not necessarily limited to the case where the GPS antenna is a pair. That is, it is clear that it is also effective as a positioning system when three or more units are installed. With this, about the work boat,
It is possible to reduce the situation in which positioning is impossible due to GPS radio interference, and it is possible to expect efficient progress in construction work and improvement in accuracy.

(4) The above embodiment is described on the premise that the pair of GPS antennas are installed at the level position on the work boat. However, reception of satellites required as much as possible during the GPS positioning time zone is possible. If it is easy, there is a benefit that the efficiency of work boat positioning improves and the accuracy increases accordingly. For that purpose, it has been known that the GPS antenna should be installed at a position away from a radio wave obstacle such as a crane or a reader, and the top of a high structure should be provided so as to shield reflection from the ground. However, it is inevitable that a positioning error will occur depending on the degree of rolling and pitching of the work boat. Therefore, if an inclinometer is attached to the high structure to correct the error, as in the other embodiment,
Positioning with high accuracy can be performed.

As described above, according to the GPS and gyro construction machine positioning system of the present invention, the number of expensive GPS antenna means can be reduced to one. Since the work boat can be positioned by one GPS antenna, the situation that positioning is impossible due to the arrangement of satellites and obstacles is drastically reduced. In a system in which a plurality of GPS antenna means are installed on the work boat, when the system is used as an assistance system, the state of non-positioning is further reduced. And so on, it is possible to obtain special actions and effects that cannot be expected from a conventionally known system of this type.
