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.
