Intelligent agricultural supervision system and method based on block chain big data

The invention relates to the technical field of agricultural data processing, in particular to an intelligent agricultural supervision system and method based on block chain big data, and the system comprises a control unit, a data collection unit, an expert recognition unit and a cloud end. A plurality of recognition models are stored in the cloud; the data acquisition unit acquires crop growth information and uploads the growth information to the block chain; the control unit extracts the growth information in the block chain, marks the plant height in the crop image, and pushes the marked crop image to the expert identification unit; the expert recognition unit recognizes the large-range growth cycle of the crops and the types of the crops, and the control unit calls a corresponding recognition model according to the expert recognition result and recognizes the small-range growth cycle of the crops; the control unit judges whether the crops are healthy or not according to the recognition result and the gro
