Agriculture generally uses a fully distributed system without a central node, namely, a wireless sensor network. By random placement, many sensor nodes are densely deployed in the monitoring area. These sensor nodes integrate sensors, data processing units, communication modules, and energy units that are connected via wireless channels and self-organized into network systems. Its purpose is to cooperatively perceive, collect and process the information of monitored objects in the network coverage area and send it to the observer. To help farmers find problems in a timely manner and accurately determine the location of the problem.
In traditional agriculture. People obtain farmland information in a limited manner, mainly through manual measurement, and the acquisition process requires a lot of manpower. Using wireless sensor networks can effectively reduce manpower consumption and impact on farmland environment, and obtain accurate crop environment and crop information. .
The application of IoT technology in agriculture can not only change the extensive agricultural management methods, but also improve the prevention and control capabilities of animal and plant epidemic diseases, ensure the quality and safety of agricultural products, and lead the development of modern agriculture.
Application of Internet of Things in Agricultural Informatization
In recent years, the term Internet of Things has appeared more and more frequently in agriculture. What is the Internet of Things? The Internet of Things is recognized by the world as the third wave of the world's information industry after computers, the Internet, and mobile communication networks. According to experts, the Internet of Things is premised on perception and realizes a fully interconnected network of people, people, things, and things. Behind this, various kinds of microchips are implanted on objects, and various information in the physical world is acquired using these sensors, and then transmitted through various wireless communication networks such as local wireless networks, the Internet, and mobile communication networks. The perception of the world.
