Abstract: In order to further optimize the operation level of automatic control of greenhouse environment in China, the optimization design of the system was studied from the perspective of electronic information and signal control. Taking the core composition and functional characteristics of the universal automatic control system as the starting point, the temperature, humidity and light intensity were selected as the main monitoring parameters of the greenhouse environment to establish the mathematical model of the electronic communication circuit, and the corresponding control implementation and hardware matching of the system were carried out. The automatic control and monitoring test operation of the system showed that the layout planning of the automatic control system of the greenhouse environment based on the application of electronic information technology was scientific and feasible, The comprehensive regulation efficiency of the system was increased by 5.80%; Due to the timely accuracy of the electronic signal monitoring feedback, the system regulation rate could be increased to 92.02%, and the greenhouse satisfaction efficiency could reach 90.11%. The application of electronic information and communication network processing technology and concepts to the regulation system and the deep integration of intelligent control and internal circuit signal processing would be one of the mainstream innovation directions of the future facility agriculture development, which would be conducive to the effective upgrading of the digitization and intellectualization of agricultural monitoring equipment, and would have good application and promotion value.
