Machine guiadnce based site control technology (SCT) for earthwork equipment fleet

In order to maximize coordination between earthwork equipment (e.g., excavators, bulldozers, graders, dumptruck and rollers) and a site office, fleet control technology is introduced in this study. Machine guidance technology is employed to enhance the performance of bucket and blade based equipment. The study consists of two parts: 1. developing a construction control center (C^3), and 2. systemizing guidance technology to provide safe and efficient equipment operation. The construction control center is stationed in a site office and produces detailed and energy saving construction plan of earthwork equipment including zoning and path planning considering the characteristics of the site contour, design information and equipment fleet. And then, earthwork processes are monitored based on the communication, comprising the exchange of design and construction information in real time, between C^3 and the machine guidance systems installed in the individual machines.
