Study on controller with online decision support system for laser-controlled leveling

Abstract

A controller and its hardware structure for laser-controlled field leveling was developed that has online decision support function. S3C44B0X and μC/OS-II were adopted as the CPU and operating system respectively. The controller has three main functions: course determination, rough/precision leveling switch and earthwork calculation. The purpose of course determination is to find the shortest transport distance and minimize the cost. The rough/precision leveling switch can increase working efficiency and reduce the wearing and tearing of the equipments. And the function of earthwork calculation is used to estimate the workload of the leveling system. Experiments showed that the online support system made the field leveling quite efficient and intelligent. © 2005 by International Federation for Information Processing.
