Abstract

[PROBLEMS] To obtain a reservoir dynamic monitoring system capable of predicting a collapse or drought of a reservoir in a short time using current water level data and rainfall data of the reservoir.
SOLUTION: The Ikego station device 2 collects measurement data obtained by measuring the water level and rainfall of an agricultural water reservoir using a water level gauge / rain gauge 1, and the collected measurement data is monitored through a line 3 for monitoring the dynamics of an agricultural water reservoir. Since it is arranged at the center, it is transmitted to the pond master station device 4, and since this is acquired from the pond master station device 4, the pond dynamic monitoring server 5 reads the past water level data and rainfall data stored in advance in the storage device, Based on these data, the water level rising trend of agricultural water ponds is grasped, current water level changes are predicted based on the current water level data and rainfall data, and the prediction results and the agricultural water ponds stored in the storage device are stored in advance. The height was compared to determine if a break or drought occurred.

Description

  This invention is intended for use in agricultural water ponds such as agricultural water ponds that temporarily store water to supply water to the fields in the event of drought. It relates to a reservoir dynamic monitoring system that is predicted in advance.

The conventional agricultural water reservoir monitoring device installs a water level meter and a telemeter slave station device in the reservoir, and transmits the water level data observed by the water level meter to the remote telemeter master station device via the NTT (registered trademark) line. However, the water level data is displayed remotely on a personal computer or the like, or the water level data is displayed on the data display panel.
Patent Document 1 describes a method for measuring an inflow amount and a discharge flow rate into a dam or a reservoir, calculating a predicted time until overflow, and notifying an operator of an alarm.
In addition, in Patent Document 2, in order to prevent the occurrence of a water disaster due to the discharge from the reservoir of the power plant overlapping the high tide of the sea, the arrival time to the discharge water level using the water level data and the rainfall data at that time Is predicted and is reported to the surrounding people.
