The birth of the Internet of Things has subverted the traditional agricultural structure, and its rational application to smart agriculture specifically includes the following functions:
First, the real-time monitoring function, connected to the Internet of Things in smart agricultural production equipment, can rely on sensors to collect relevant data and information in greenhouse facility agriculture, such as soil temperature in the greenhouse, air humidity, carbon dioxide, soil moisture, light, greenhouse External wind speed, temperature, etc., with the help of the Internet of Things, the data will be transmitted to the service management platform in time, and relevant data will be analyzed and processed, and farmers will make targeted adjustments to ensure the good growth of crops.
Second, the remote control function. Install electromechanical equipment in farmland and greenhouses where conditions permit, such as electric irrigation systems, exhaust fans, electric roller shutters, etc., and agricultural managers log in to the system through mobile phones and computers. The water valve switch, exhaust fan, and shutter machine can be controlled remotely. Customers can also be entered according to the actual conditions of facility agriculture, and the control logic can be set. The system opens or closes the electromechanical equipment of the greenhouse according to the actual situation.
Third, the query function. Realizing information query is one of the important functions of Internet of Things technology, that is, agricultural workers can use information terminal equipment to conduct real-time query on various information of smart greenhouses, including greenhouse environmental conditions, equipment operation records, historical images and environmental change curves, etc. content. In addition, after logging into the information management system, it is also possible to understand information such as market conditions, agricultural policies, and professional announcements through information exchange with network databases, and solve the problem of information asymmetry.
Fourth, the warning function. The warning function is an important component of the smart greenhouse, that is, by setting thresholds for various information devices in advance, once the sensor information of the greenhouse is abnormal, the alarm function will be triggered, so the emergency situation in the greenhouse can be quickly grasped and resolved, ensuring the safety of agricultural products. Safety.
WiFi technology, RFID technology, sensor network technology, GNSS positioning, etc. are widely used in smart agriculture
