Design and research of intelligent agricultural greenhouse based on agricultural internet of things technology

At present, with the advent of 5g and big data technology era, the development of intelligent agriculture industry based on information technology has been applied, in which the Internet of things is widely used to enrich planting technology, optimize the traceability of agricultural products, and ensure the organic combination of information technology and intelligent agriculture. By analyzing the indicators of greenhouse monitoring, this paper puts forward the standard architecture scheme of Intelligent Greenhouse Based on Agricultural Internet of things: in the perception control layer, the wireless sensor module detects soil moisture, environmental temperature and humidity and illumination, and uses the relevant knowledge of data fusion to start the control equipment such as lighting, temperature control and gas concentration, In the network transmission layer, Siemens S7-200 smart PLC and stm32f030c8t6 constitute the dual control core, sm3390b sensor is used to collect and monitor data, and the data hub between system layers is established; The terminal application layer adopts the visual man-machine interface of weiluntong, which can view the environmental monitoring data at any time and place. The simulation results show that the system has low cost but high automation level, which is of guiding significance to further improve the development of agricultural planting in China in the direction of intelligence.
