    Abstract: An intelligent system and a method for coordinating harvester and logistics vehicle are illustrated. The intelligent system comprises a harvester terminal and a logistics vehicle terminal. The harvester terminal comprises a repository monitoring module and a control module, wherein the repository monitoring module monitors storage information of a storage bin of the harvester. The control module receives the storage information from the repository monitoring module, and determines whether the storage location of the storage bin of the harvester reaches a preset location. The harvester terminal and the logistics vehicle terminal are communicatively connected. When the storage location of the storage bin of the harvester reaches the preset location, the control module sends a transport instruction to the logistics vehicle terminal to control the logistics vehicle to transport grain, thereby achieving intelligent coordination between the harvester and the logistics vehicle.
