Intelligent Plant Protection System of Greenhouse Based on Plant Phenotypic Discrimination Warning

In order to realize intelligent plant protection through plant phenotype in greenhouse, this paper designs a greenhouse intelligent plant protection system based on plant phenotype discrimination warning by combining mobile device, dispensing barrel, spraying device, visual device and central control unit. In this paper, the crop phenotype is monitored by visual device to distinguish the type and degree of diseases and insect pests, and early warning is carried out to assist the administrator to select the medicament in time and accurately, to automatically dispensing the medicine, and to plan the navigation route by the central control unit. And according to the degree and position of diseases and insect pests real-time adjustment of spray nozzle, to achieve the combination of treatment and prevention. The system has the advantages of accurate application, water saving and fertilizer saving, green development, strong adaptability and intelligent management, which can effectively avoid pesticide poisoning of workers, and provide a solution to promote the safety and accuracy of plant protection in greenhouse.
