合せて親局に返送することも考えられる。Furthermore, in the present invention, data is stored in each slave station by a simultaneous signal from the master station, but in order to make the time more clear, the relevant time or a signal equivalent to this is also included in the simultaneous signal. It is also conceivable that when the observation data is transmitted and stored in the slave station, this time signal is also stored, and the data and time signal are combined and sent back to the master station.
以上説明したように、本発明によれば、親局からの一斉
信号により全く同時刻に各子局が観測データを採取する
ようにしているため、全系の状態を同時に把握すること
ができるという効果かある。As explained above, according to the present invention, since each slave station collects observation data at exactly the same time using a simultaneous signal from the master station, it is possible to grasp the status of the entire system at the same time. It's effective.
従って、広域の水管理システム等においては、同一時点
