Abstract
Ensuring safety of the Operator of the Construction Machinery is an important issue in the disaster restoration spot and Danger environment. Construction Machinery of the Remote Control is used in the environment where a human being cannot enter. It is thought that the Remote Control greatly has decreased Operating Efficiency in comparison with boarding operation. A lot of causes of the drop of the Operating Efficiency are thought about, and one of the big factors is transmission delay of the images. Therefore the authors built a Remote Control system of the Hydraulic Excavator using the spot radio and public cable broadcasting network to confirm a problem of the Remote Control. And a system used Remote Control of the built Hydraulic Excavator and performed inspection about the transmission delay time for picture. This report introduces delay time of the video transmission with a built Remote Control system.
