SOLUTION: The data transmission system transmits the measured data of the physical amounts, such as the amount of rainfall or the like, to an external managing terminal. The system comprises a field server having a data collecting means for collecting the measured data, a data processor for forming a data file based on the measured data collected by the collecting means, and a file transfer means for transferring the data file to the managing terminal via a communication network.</p> |
