Digitalized tunnel face mapping system (DiTFAMS) using PDA and wireless network

초록

Accelerated development of information technology introduces a new way of decision making tool at the construction job sites. Especially wireless network technology as well as portable computing machine such as Personal Digital Assistant (PDA) can be a versatile decision making system for underground construction. This paper introduces the Digitalized Tunnel Face Mapping System (DiTFAMS) using PDA and wireless network. The DiTFAMS can record the RMR and Q system parameters and approximate sketch of joints pattern in the text and bitmap formats and compute the RMR and Q values at the tunnel face. Once the collected data are transmitted to the main server through the wireless network, the main PC sever classifies the text and image data sent from the PDA. From the collected data redesign of tunnel supports is possible, if it is required. The virtue of system is the ease on the use and search of the collected data which are in a digital format, so rapid decision making during the construction is possible.
