The invention discloses a real-time monitoring management system of intelligent agriculture based on big data. The real-time monitoring management system of intelligent agriculture based on big data comprises a rice field environment parameter detection module, a soil nutrient parameter detection module, a parameter pre-processing module, an image acquisition module, an insect disease classification identification module, a management database, a remote server, an irrigation analysis module, an execution terminal and a display terminal. According to the real-time monitoring management system of intelligent agriculture based on big data in the invention, related environment parameters of a rice field are acquired; irrigation environment influence coefficients of the rice field are counted;then, the irrigation amount corresponding to the area of the rice field is obtained according to the water demand of the unit rice field area corresponding to various growth periods of rice; in combination with acquisition processing of rice growth images, insect disease types are analyzed and identified; the pesticide type and the pesticide amount are determined; simultaneously, the nutrient kinds and contents of soil in the rice field are detected; the nutrient kinds and the contents deficient in the soil of the rice field are analyzed; the execution terminal is controlled to quantitativelyexecute irrigation, fertilization and pesticide spraying operations; and thus, precise control of the rice irrigation amount, the fertilization amount and the pesticide spraying amount is greatly increased.
