Design And Research Of Agricultural Information Acquisition System Based On Embedded Linux

Precision agriculture is the direction of modern agricultural development.Applying embedded data collection technology to agricultural production process can not only save manpower and material costs,but also increase crop yield and quality,reduce pesticide pollution and improve production efficiency.In the precision agricultural production process,it is necessary to collect and monitor data during the growth of crops for decision making.In order to realize the information collection in the agricultural production process,this paper mainly studies the collection,transmission and control of agricultural production information,and designs a set of agricultural information collection system based on embedded Linux system.In view of the collection,transmission and control of key data in the process of crop growth,this paper designs Cortex-A8 as the core processor and embedded Linux as the operating system.The GPS satellite positioning technology and agricultural information acquisition sensor technology are used to grow crops.Geographical location,ambient temperature and humidity,light intensity,climatic conditions,soil composition and other information are collected in real time.The data is collected and managed locally using the SQLite database.The local 7-inch LCD screen displays real-time data and sets system parameters.4G wireless communication technology,the collected data is transmitted to the background server in real time,and the background server can issue commands to control the local electronic switch,so as to control the sprinkler irrigation,fertilization,ventilation,illumination and other switches of the crops,and realize agricultural information collection and transmission.,remote or local automated control system.This paper organically combines embedded Linux system,SQLite database and mobile 4G communication in agricultural information collection system,and uses Linux system open source,croppable,multi-tasking,multi-threading,powerful network and other advantages to ease the difficulty of application design.Use SQLite database to efficiently store management data,realize flexible data addition,deletion,check,change,etc.,realize real-time transmission of collected data and remote control through mobile 4G communication technology.Experiments show that the agricultural information collection system designed in this paper can quickly and efficiently complete the local collection,storage and display of agricultural information,and upload the collected data to the backend server in real time,as well as remotely control crop irrigation,fertilization,ventilation,lighting,etc..The system can be applied to greenhouse cultivation,farmland planting,flower nursery and other occasions.
