DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wide-area work management system used when performing large-scale construction at sea, on land, or the like.

[0002]

2. Description of the Related Art When an artificial island is constructed on the sea, large-scale earth and sand collection and land development are performed on land, the construction area is wide. Therefore, in such large-scale construction, it is extremely important for each vehicle or ship to know its own position accurately in terms of construction accuracy. Recently, GPS has been widely used as a method for performing such position surveying. It has come to be.

[0003] GPS is a positioning system that can determine its own position by receiving a radio signal from a GPS satellite, and is initially used for navigation (navigation support) of moving objects such as aircraft and for providing time information. Although developed, various positioning methods such as an independent positioning method, an interference positioning method, and a differential method (DGPS) have been developed and are widely used in the field of surveying.

Here, in the wide area construction using GPS, each work vehicle or work ship measures its own position by GPS surveying, and the relative positional relationship with another work vehicle or work ship, the order of work, and the like. For, collisions and mutual interference of work were avoided by communicating via wireless voice.

[0005]

However, in such a method mainly based on voice communication, it is impossible to avoid a time lag or lack of accuracy in information transmission, so that a work vehicle or a work boat cannot be used. Especially when the number is large or the work process has no margin, the work efficiency may be reduced due to the interference between the work vehicles or work boats, or in the worst case,
There has been a problem that a contact accident may not be avoided.

[0006] Although each work vehicle or work boat can grasp or manage its own construction performance, the work performance or work status of other work vehicles or work boats is managed as described above. However, there is a problem that there is a limit in terms of immediacy and accuracy.

[0007] Such a problem similarly arises in the case where the operation status of each work vehicle and each work boat and the progress status of the entire construction are centrally managed, and information transmission such as work instructions and operation instructions from the central management side is not performed. This has led to delays and inaccurate decisions on the central management side.

The present invention has been made in view of the above-mentioned circumstances, and even when a large number of work vehicles or work boats are interlaced or there is no room in the work process, the operation status and work status of those work vehicles and work boats can be checked. It is an object of the present invention to provide a wide-area work management system that can accurately grasp in real time and ensure high construction efficiency and safety.

Thus, collision and work interference can be avoided beforehand.

According to the wide-area work management system of the present invention, it is possible for the management side to predict the movement of each work moving body, and it is possible to more reliably prevent a collision or work interference. It also has the effect of being able to do it.

According to the wide-area work management system of the third aspect of the present invention, it is possible to predict the movement of another work moving body on the side of each work moving body, without waiting for an instruction from the management side. In addition, there is an effect that a situation such as a collision or work interference can be more reliably prevented by a user's own judgment.

Further, according to the wide area work management system of the present invention, each work moving body can move by following the guidance of the operation instruction information given from the management side, and can move by itself. There is also an effect that the efficiency of the entire work and the safety of movement can be ensured without making a judgment.

Further, according to the wide-area work management system of the present invention, it is possible for the management side to centrally manage the work progress status of each work moving body. In addition, if such work information is written in the storage device of the management computer, various construction management records can be output to the output means at any time, and compared with the conventional construction system that relied on voice communication. Also, there is an effect that large labor saving, speeding up and improvement of accuracy can be achieved.

According to the wide-area work management system of the present invention, it is possible for each work moving body to grasp the work progress status of another work moving body. Also play.

According to the wide-area work management system of the present invention, each work moving body only works in accordance with work instruction information given from the management side, and does not judge by itself. In addition, there is an effect that efficient work can be performed.

Further, according to the wide-area work management system of the present invention, it is possible for each work moving body to work safely while grasping the surrounding environment. Play.
