Real-time irrigation forecasting system based on regional soil moisture monitoring and remote sensing data

Abstract

The invention belongs to the technical field of irrigation forecasting. The invention discloses a real-time irrigation forecasting system based on regional soil moisture monitoring and remote sensingdata. The real-time irrigation forecasting system comprises an irrigation area monitoring module, a crop image acquisition module, an environment data acquisition module, a central control module, a soil moisture prediction module, an irrigation area identification module, an irrigation prediction module, an actual water consumption module, a watering module, a water level depth measurement module, an alarm module, a wireless communication module, a data storage module, a data management module, a terminal module, a power supply module and a display module. According to the real-time irrigation forecasting system, the prediction precision can be improved and the generalization ability can be ensured through the soil moisture prediction module, so that large-scale deployment and expansion are facilitated, and better expandability and transportability are achieved; the irrigation area recognition module meets the requirement for extracting irrigation information of small plots, so that the precision of an irrigation area monitoring result is improved; and the real-time irrigation forecasting system can be widely applied to remote sensing identification and extraction of irrigation areas with high spatial resolution.

Description

technical field [0001] The invention belongs to the technical field of irrigation forecasting, in particular to a real-time irrigation forecasting system based on regional moisture monitoring and remote sensing data. Background technique [0002] Irrigation is a technical measure to replenish the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. Irrigation, i.e. irrigating the land with water. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions, and should b...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the method for obtaining moisture content in the root zone of the crop in the process of crop irrigation is expensive and requires a huge amount of engineering, which leads to the defects of insufficient decision-making accuracy and large errors in the irrigation decision-making methods; , cannot accurately identify the irrigated area
