Abstract

The invention provides a greenhouse automatic control system, which is characterized by comprising an upper computer used for monitoring and giving instructions, a data acquisition receiver for acquiring and receiving data, an electromechanical control operation unit, and a programmable logic controller which is connected with the upper computer, the data acquisition receiver, and the electromechanical control operation unit and used for controlling the upper computer, the data acquisition receiver and the electromechanical control operation unit. The programmable logic controller comprises an input module connected with the upper computer and the data acquisition receiver and an output module connected with the electromechanical control operation unit. The input module sends the data processed by the data acquisition receiver to the programmable logic controller and the upper computer, then the programmable logic controller processes the data and then sends the data to the output module, and the electromechanical control operation unit is controlled to perform operation.

Description

technical field [0001] The invention relates to the field of greenhouse environment control and irrigation, in particular to a greenhouse automatic control system for greenhouse drip irrigation automatic production and greenhouse comprehensive cooling. Background technique [0002] At present, countries all over the world are actively researching the impact of greenhouse comprehensive intelligent control technology on crop production and cost optimization, but a large number of irrigation systems or greenhouse electromechanical control have not studied soil information input variables, greenhouse environmental factor variables, and crop transpiration. speed for comprehensive control and data analysis. Taking the above problems into consideration, this patent uses soil information input variables, greenhouse environment factor variables, and crop transpiration rate as the input of the control system to dynamically determine the key variables that trigger greenhouse production...
