Description

Irrigation Control System for Overcomeing Submergence and Drought}

The present invention relates to an irrigation control system for overcoming flooding and drought, and more particularly, to an irrigation control system for overcoming flooding and drought capable of efficiently utilizing rainwater using a rainwater storage facility.

Due to climate warming, agricultural land flooding damage due to torrential rains is increasing every year, and disaster losses are also occurring in urban areas. Installation of rainwater retention facilities is compulsory for new towns or building developments of a certain scale, and some local governments spend a lot of money to expand rainwater storage facilities, but utilization is low.

The Rural Development Administration announced that it would allocate 1.961 trillion won in the budget for 2021 and reflect it in future technology development and dissemination projects to respond to climate change, and rain city creation projects that efficiently use rainwater are spreading across the country.

In addition, rainwater is rich in nitrogen, minerals, oxygen, etc., which are necessary elements for plant and crop growth, so it serves as a fertilizer, prevents diseases and damage to crops due to groundwater salt by using rainwater. Crop water uptake is mostly in the topsoil, replenishing 40% of plant water in the surface layer below 30 cm. Lack of moisture is the biggest problem for growth in all crops. Therefore, automatic irrigation equipment or technologies for facilitating water supply to crops have been introduced.

Therefore, research and development on how to utilize rainwater in such an irrigation facility is required.

Referring to FIG. 6 , the cloud server 12 scans the water supply terminals of each registered water supply pond through the communication network 14 (S100). The scanned irrigation pond terminals upload environmental data and status data. Accordingly, the server 12 analyzes the uploaded environmental data and state data to diagnose whether the irrigation pond is out of order (S102). As a result of the diagnosis, it is determined whether a risk factor has occurred (S104). When an abnormality occurs in step S104, the user terminal 18 is informed of the occurrence of an abnormal state and returns to step S100. In step S104, if the state is normal, the uploaded environmental data is analyzed (S106) and growth data is analyzed (S108). These assays are used to control crop irrigation.

Next, the meteorological information of the irrigation area is analyzed (S110).

Subsequently, the water level of the irrigation tank 210 is checked (S124). When the water level of the irrigation tank 210 is at the set low level, the supply pump 330 of the rainwater storage facility 300 is operated to supply rainwater to the irrigation tank 210 (S126). Subsequently, when the water level of the irrigation tank 210 becomes high (S128), the supply pump 330 is stopped (S130) and the program returns to the main program.

Referring to FIG. 8 , the irrigation pond terminal 16 that has downloaded the control command from the server 12 first operates the drainage pump 350 in order to promptly drain the flooded state of the irrigation pond in the flood response irrigation control mode (S132 ). The drainage pump 350 is operated to maintain the water level of the rainwater storage tank 320 at a low level so that the rainwater from the irrigation pond is quickly drained through the rainwater storage tank 320 to quickly escape the flooded state of the irrigation pond. . Subsequently, the water level of the irrigation tank 210 is checked (S138). When the water level of the irrigation tank 210 is the set low level, the supply pump 330 of the rainwater storage facility 300 is operated to supply rainwater to the irrigation tank 210 (S140). Subsequently, when the water level of the irrigation tank 210 becomes high (S142), the supply pump 330 is stopped (S144) and the program returns to the main program.

9 is a flowchart illustrating the operation of a preferred embodiment of a control program in drought mode.

Analyze (S148). The supply amount is determined by calculating the rainwater supply amount according to the stored water amount and inflow amount of the analyzed rainwater storage tank 320 and the expected drought days (S150). That is, when the water storage amount of the rainwater storage tank 320 is divided by the expected drought days, the daily supply amount is calculated, and the daily supply amount is determined to determine the water supply amount in preparation for drought. Subsequently, the water level of the irrigation tank 210 is checked (S152). When the water level of the irrigation tank 210 is at the set low level, the supply pump 330 of the rainwater storage facility 300 is operated to supply rainwater to the irrigation tank 210 (S154). Subsequently, when the water level of the irrigation tank 210 reaches the supply amount level (S156), the supply pump 330 is stopped (S158) and the program returns to the main program.
