AN AUTOMATIC MONITERING SYSTEM FOR OBSERVED GROUND WATER

摘要

PURPOSE: An automatic monitoring system for observed ground water is provided to prevent the exposure of various data in spite of a wiretapping or leakage in a data transmission process. CONSTITUTION: Various data of underground water obtained by a sensor probe are coded by a sensor probe installed in a tube well(21,22). Data coded at each underground observing network is transmitted to a central control station by an encrypted communication system by wire/wireless(23). Various coded data of underground water from each underground observatory is decoded at the central control station and various data of underground water measured at each underground observatory is obtained(25).
