Dam control information system using IP network

摘要

Since NTT DoCoMo started i-mode services in February 1999, i-mode mobile phones have widely spread owing their Internet accessibility and superior portability, and regarded as one of the best tools for information gathering in the IT industry. Taking advantage of the Internet accessibility of i-mode mobile phones, we have developed a dam control information system to disseminate dam information to i-mode mobile phone users on Internet. This system ensures not only up-to-date dam information to be disclosed to the public, but also dam operation alarms to be informed by e-mail to dam operation personnel due to support taking quick actions. This report describes the configuration and functions of the dam control information system and outlines its technical specifications, referring to the system in operation at Haji Dam under the control of Chugoku Regional Development Bureau, Ministry of Land, Infrastructure and Transport.
