Agricultural water automatic supply system {AN AGRICULTURAL WATER AUTOMATIC SUPPLY SYSTEM}

The present invention relates to an automatic agricultural water supply system, and more particularly, it automatically measures the water level at each base in farmland, and when the measured base water level is low, automatically opens a sluice switch close to the base to automatically supply agricultural water. Also, by transmitting the water level at each base and the water level in the irrigation canal to the central management server, it is possible to grasp the real-time water level for each base in the farmland and the water level in the irrigation channel, as well as supply the DB of the central management server to the personal terminal. It relates to an automatic agricultural water supply system that enables manual control of the central management server.

In general, agricultural water refers to irrigation water that artificially supplies water to paddy fields and fields for the purpose of producing crops.

Korea is classified as a country with severe water shortage, and systematic management of agricultural water, which accounts for about 50% of water usage, is required.

The purpose of the management of agricultural water is to accurately use the limited water resources and to efficiently use the limited water resources by establishing an appropriate irrigation schedule by accurately calculating the supply period and amount of irrigation required in the field, and then performing water management according to the irrigation plan in the field. to maximize productivity improvement.

Therefore, there is a need for an agricultural water management system capable of unified management from the water source to the waterway organization and field in order to determine the optimal irrigation time and relative amount under conditions of abundant or insufficient agricultural water.

On the other hand, the agricultural water management system according to the prior art calculates the daily irrigation amount according to the size of the water source by estimating the required amount according to the area of the pavement, and water management is performed based on the past experience of the local manager in the actual field. am.

In other words, in the prior art, daily irrigation through a water balance model that simply compares the daily watershed inflow according to the size of Suwon Gong and the required amount according to the area of the pavement without considering the size, type, system, and arrival time of the waterway organization. The quantity was calculated.

For this reason, it is difficult to predict or understand the water supply and demand situation in the waterway organization and pavement according to irrigation, and it is impossible to actively control the supply and demand of water, making it difficult to make decisions in an emergency.
