Field of the Invention The present invention relates to a compaction management system using GPS, and more particularly to a system for controlling the number of compaction vibrations of compaction vibrating rollers (hereinafter, also referred to as compaction roller wheels) on an embankment.

[0002]

2. Description of the Related Art Conventional quality control of an embankment is carried out by a sand replacement method, a water replacement method, an RI method, etc., but all of them require a great deal of labor and time for compaction. Sometimes, it hindered smooth embankment construction.

As one of the alternatives to these conventional methods, it has been proposed to take the running distance of the vibrating roller as an index of the degree of compaction and use it for compaction management. It is practically used in some construction as a task meter method. Have been served. However, it has been pointed out that the task meter method has a drawback in that it does not have an index for confirming that the target embankment is uniformly compressed, although the traveling distance of the vibrating roller is accurately grasped.

Further, in the task meter method proposed above, it is not possible to strictly manage the number of rolling compactions represented by the number of times the vibrating roller travels on the embankment, and it is difficult to grasp the progress of the work. There were problems such as being there. In addition, there were cases where the ground did not reach the specified strength in the test after the compaction, and it was necessary to apply compaction again to the insufficient compaction area.

Therefore, it is an object of the present invention to provide a compaction management system using GPS capable of strictly controlling the number of times of compaction.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1, 2 and 3, the coordinates of two GPS antennas 8 and 9 on a roller wheel 2 are G.
It can be determined by the PS survey method. In the example shown,
The GPS antenna 3 and G are attached to the fixed station 1 by using the relative positioning method.
Two GPS equipped with PS receiver 4 and mounted on roller car 2
The antennas 8 and 9 are used as mobile stations and GP for each mobile station is used.
The S receivers 10 and 11 are mounted on the roller wheel 2.

According to the GPS relative positioning method which belongs to the publicly known art, the coordinates of the mobile station GPS antenna 8 are known coordinates of the fixed station 1, the radio wave information received by the GPS receiver 4 of the fixed station GPS antenna 3 and the mobile station antenna 8. GPS receiver 10
It is calculated from the difference with the received radio wave information. Also, the mobile station G
The coordinates of the PS antenna 9 are obtained from the known coordinates of the fixed station 1 and the difference between the reception radio wave information of the GPS receiver 4 of the fixed station GPS antenna 3 and the reception radio wave information of the GPS receiver 11 of the mobile station antenna 9. The transmission modem 5 of the fixed station is G
This is for transmitting the reception radio wave information of the PS receiver 4, and the reception modems 12 and 13 of the mobile station receive the reception radio wave information from the GPS receiver 4 and receive the GPS receivers 10 and 11 respectively.
To add to. GP of roller car shown in FIG.
The position calculating means 27 of the two S antennas is, for example, G of the mobile station.
It is incorporated in the PS receivers 10 and 11, and the positions or coordinates of the GPS antennas 8 and 9 are calculated from the received radio wave information from both antennas and the received radio wave information from the fixed station 1. However, the present invention is not limited to the GPS relative positioning method as long as the positions of the two GPS antennas 8 and 9 on the roller car 2 can be measured.

When the roller car 2 is remotely operated, the image 2I of the roller car 2 is displayed on the fixed station 1 or the central control room. Therefore, the outputs of the position calculating means 27 of the two antennas are sent to the personal computer 7 of the fixed station 1. It is added to the roller vehicle position / orientation detecting means 29 inside. The data transmitter 14 and the data receiver 6 of FIG. 2 are for this purpose. When displaying the roller car image 2I only on the roller car 2, these data transmitters 14 and receivers 6
Can be omitted.

Referring to FIG. 4, if the positions of the two GPS antennas 8 and 9 on the roller car are 17a and 17b, respectively, and the line segment between the two positions is the base line 17, the base line 17 and the roller car will be described. The geometrical relationship between the two body corners 18, namely 18a, 18b, 18c, 18d, is constant. Therefore, if the position and direction of the base line 17 are detected, the position and direction D of the roller wheel 2 can be determined. The position calculating means 27 for the roller wheel 2 can be configured based on this principle. Further, although the drawing shows the roller wheel 2 in a plan view, the inclination of the roller wheel 2 can be taken into consideration within a certain range, if necessary.

As shown in FIG. 3, a ground mesh composed of a group of mesh sections obtained by dividing a zone to be compacted (compacted zone) of the ground 20 with an appropriate pitch S, for example, a vertical line L and a horizontal line M having a pitch of 1 meter. It can be displayed as image 20I. The mesh section storage device 28 of the compaction area stores the data of the ground mesh image 20I that is separately created and displays it on the display 22 of the personal computers 7 and 15. As can be understood from FIG. 4, the pitch S of the vertical line L and the horizontal line M is set to be narrower than the width Wa of the pressure roller 24 of the roller wheel 2.
It is desirable to provide an overlap between adjacent roads with a lap width Wb during traveling.

The roller vehicle position / orientation detecting means 29 superimposes and displays the image 2I of the roller vehicle 2 on the ground mesh image 20I based on the output of the position calculating means 27 of the two antennas. When the roller wheel 2 is remotely controlled, the direction D of the center line of the roller wheel 2 is changed by the traveling control means 31 to, for example, the adjacent vertical line L.
It is possible to drive while matching the center line C between the two. In this way, by monitoring the movement of the roller wheel 2 of the image, compaction roller 24 rolling pressure range of the roller wheel 2 of the ground 20
It is possible to sequentially detect and monitor the compaction. By monitoring it, the number of times of rolling compaction for each mesh section is detected.
The storage unit 32 detects the number of times of compaction for each mesh section by an image processing method and stores the detection result. The monitoring result of the traveling locus of the compaction roller 24 of the roller wheel 2 and the detection result of the number of compaction times are displayed on the display 22 by the locus / compacting number display means 33.

The personal computer 15 on the roller wheel 2 in FIG. 1 is the same as the personal computer 7 of the fixed station 1, and when the operator manually operates the roller wheel 2, the personal computer 15 monitors the number of rolling pressures online. Can be

The displayed rolling number can accurately digitally display the rolling result up to the current position of the roller wheel for each mesh section, and the running of the roller wheel can be controlled. Can be managed.

Thus, the object of the present invention is to provide a "compacting management system using GPS capable of strictly managing the number of times of compaction".

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in FIG. 1, the color assigning means 34 displays the number of rolling compactions in different colors for each rolling compaction count. For example,
