How does a smart agricultural system based on the Internet of Things promote agricultural development?
A foreign research team named Our World in Data conducted such a survey: Half of the world's habitable land has been used for agriculture, and animal husbandry accounts for 77% of the global agricultural land. Although animal husbandry occupies most of the world’s agricultural land, it only produces 18% of the world’s calories and 37% of the total protein. Insufficient agricultural land and low utilization rate are a common problem. With the continuous growth of population and the frequent occurrence of natural disasters in recent years, the problem of agricultural land has become more and more serious. Under this major premise, in addition to protecting agricultural land from being occupied, it is urgent to use land efficiently. The rise of smart agriculture has made a great contribution to improving land utilization. Smart agriculture is the product of my country’s transformation from traditional agriculture to modern agriculture, and is an important development direction of agricultural modernization. In recent years, as the country has accelerated the process of agricultural modernization, the transfer process of rural land contractual management rights has accelerated, and the scale of agricultural production and operation has continued to expand. At the same time, smart agricultural systems continue to increase, and the requirements for smart agricultural efficiency are beginning to become higher and higher, and smart agricultural systems based on the Internet of Things are urgently required to be launched. What is a smart agricultural system based on the Internet of Things? The smart agricultural system can be divided into three layers based on the Internet of Things: application layer, transmission layer and perception layer. The perception layer of smart agriculture: As the name suggests, the perception layer is actually a hardware layer dominated by sensors. Smart agriculture sensors are classified into soil temperature and humidity sensors, soil parameter sensors, and various gas sensors. It can monitor the growing environment of crops in real time, monitor various farms and so on. Only by monitoring the data can a proper solution be obtained. Transmission layer of smart agriculture: The transmission layer uploads data obtained by sensors to the monitoring terminal through data upload. That is, the communication between the hardware layer and the software layer. At present, in addition to the well-known data upload methods such as GPRS/4G/5G, there are: RS485, Ethernet, Zware, ZigBee, NB-IOT, Bluetooth, WiFi, etc. The application layer of smart agriculture: The application layer can also be called the software layer, which is mainly used by the agricultural terminal system to analyze and process the data collected by the sensors. The software system data of the application layer can be produced and viewed on computers, mobile phones or other smart terminal devices. Check the status of real-time or past smart agricultural sensors through the official website of the sensor or the mobile APP, and analyze and process the data through the operation interface. Real-time control of the on-site environment based on the results. Importance of the Internet of Things in the Smart Agricultural SystemSensors have been developed as early as the last century and applied to people’s daily production and life. The Internet of Things was formally proposed in 2005, and it has only been widely used in agricultural production in recent years. The emergence of the Internet of Things has completely subverted the traditional farming mode of agriculture, digitizing and informatizing all environmental elements. Promote the further development of agriculture in the direction of smart agriculture and precision agriculture. In addition, the smart agriculture system is equipped with the Internet of Things, which makes it possible to trace the growth process of agricultural products in the whole process. It can also effectively realize the industrialization of agricultural production. Standard implementation, increase land utilization and unit output, and promote farmers' income. Smart agriculture will be the development trend of our country and the future development direction of agriculture. With the further development of information technology, it is believed that smart agriculture based on the Internet of Things will be applied in a wider range.
