G-Lab is a digital intelligent management platform based on the interaction with the expert database in the cloud to manage relevant software and hardware, covering three parts: model library, model algorithm and operation interface. Through the G-Lab big data simulation computing platform and its data flow, it is possible to digitally integrate the design module, internal environment control module and automation system platform module of the fully controlled industrial greenhouse, effectively improving the automation, mechanization and intelligence level of greenhouse production, thereby forming The core competitiveness of fully controlled industrial greenhouses. The model library includes the fifth-generation semi-closed greenhouse, plant model, automation system platform and sales data.
