Crop group collecting, transmitting and controlling system based on one-driving-N management and control mode as well as control method

The invention provides a crop group collecting, transmitting and controlling system based on a one-driving-N management and control mode. The system comprises a master controller, an information collection unit arranged in each crop unit, an expert data storage unit, a comparator, auxiliary controllers and execution units connected with the auxiliary controllers, wherein the expert data storage unit and the comparator are connected with the master controller, and the auxiliary controllers are connected with the master controller through communication units. With the adoption of the scheme, only one information collection unit for connecting actual environment parameters of all agricultural greenhouses is arranged in each crop unit, and the actual environment parameters and environmental parameter threshold values in the expert data storage unit are randomly compared by the comparator, so that whether crops in the greenhouses are in the optimal environment is judged, and a control decision of the master controller is formed; meanwhile, the control decision of the master controller is duplicated and transmitted to each auxiliary controller, a master-auxiliary management and control mode that one master controller controls multiple auxiliary controllers is realized, the usage cost is effectively reduced, and the crop environment is optimally controlled.
