| Research Abstract |
(1)A compact and relativerly cheap system for measuring environmental data near the ground was developped. The system is composed of a small DC genearator works with propane gas, a data logger, a wireless telephone, a modem, poles, a small hanger. The measuring system is useful at no AC-electricity and no telephone line.
(2)We set up total 6 sets of the measuring system at hokkaido(3 sets), Tsukuba city, Sakai city, Yamaguchi city, and constracted measuring network. Evapotranspiration and heat badget were measured continuously for long periods at the 6 places by 5 research institutions.
(3)We made software for acquisiting and telemetering from the measuring systems at desired time. It is possible for every users to access directly to the measuring systems and get data from the systems, if they have a computer with a modem, a telephone line and the software. Then every users can be like a data acquisition center.
(4)We made a communication network among 5 institutions with such as PC-VAN for sending and recieving results of analyzed data among institutions.
(5)Through (1)-(4), we acomplished a measuring, data acqusitioning and communicating network system.
