1.WiFi technology
WiFi technology is a technology that allows electronic devices to connect to a local area network. It can support wireless Internet access of many electronic products and implement wireless network transmission. WiFi technology undertakes the task of information perception in intelligent agriculture applications. The environment and other information collected by sensors need to be supported by WiFi technology in the aspect of information perception, and the information collected and transmitted to the application analysis level is also needed. WiFi technology makes it efficient and secure. It can be said that WiFi technology is the basis of the application of Internet of Things technology in intelligent agriculture. Without the support of WiFi technology, Internet of Things technology can not play its due role.
2.RFID technology
RFID technology, that is, radio frequency identification, is a kind of communication technology. The main principle is to use radio signals to sense the target and record the data. It consists of three main components: a transponder, a reader, and an application software system. The operation process in the Internet of Things technology is: after the reader detects the signal, the RF signal is emitted through the antenna at a corresponding frequency, and the application software system performs information processing after receiving the information frequency signal, and the chip inside the device will be stored. After the information is transmitted, the reader receives the frequency signal again for data analysis and processing, and transmits it to the background operating system to control the information data.
3. Sensor network technology
The sensor network technology integrates sensors, data processing unit components and communication components in a region where information collection and transmission are required, and is randomly distributed to form a network structure, which is a sensor network. The number of nodes is relatively large, and it is highly adaptable in a complex and varied environment. Although its information transmission capability is relatively limited and there is a certain degree of interference between signals, since the data transmitted by a single node component is small, the influence is small. Due to the dense and random distribution of nodes, they need to have a certain degree of energy storage. Sensor network technology can be said to be the core of the Internet of Things technology. It plays an important role in the connection between objects and objects for information exchange and transmission.
1. The application of Internet of Things in agricultural production
The application of Internet of Things technology in agricultural production has solved the problem of “good seedingâ€, especially in greenhouse field planting, livestock and poultry aquaculture, and agricultural machinery Internet of Things.
First, monitoring environmental changes to achieve intelligent management, dynamic changes in plant growth environment information monitoring environment acquired by wireless or wired sensing nodes, solar power supply systems, information collection devices, transmission systems, etc. Monitor soil moisture, soil temperature, air temperature, air humidity, light intensity, plant nutrient content and other parameters. According to the feedback of various parameters above, the agricultural park is automatically controlled by automatic irrigation, automatic cooling, automatic rolling, automatic liquid fertilizer application and automatic spraying.
The second is to monitor real-time images and control real-time status. The reference of video surveillance in agricultural parks intuitively reflects the real-time status of crop production and livestock aquaculture to provide farmers with timely adjustments to the breeding program and scientific decision-making.
2. The application of Internet of Things in agricultural supervision
Food is food to safety first. The application of Internet of Things technology in agricultural supervision solves the problem of “good management†of agricultural product quality and safety.
The first is to realize the ecological environment monitoring of agriculture. The agricultural ecological environment is the basis for affecting the quality and safety of agricultural products. The use of the Internet of Things technology to collect information on agricultural soils through information transmission for accurate analysis can not only produce corresponding crops suitable for detecting soil growth, but also detect some undetectable problems in the soil that are invisible to the naked eye. improve. The Internet of Things technology not only detects the sudden environment, but also the atmospheric environment and water environment. The water environment is tested to ensure that there are no microorganisms and heavy metal ions in the water source that affect the growth of crops and endanger human health. The atmospheric environment is tested to detect toxic gases such as sulfur dioxide and nitrogen dioxide in time, so as to take timely measures to improve the surrounding atmospheric environment and ensure the healthy growth of crops.
The second is to realize the traceability supervision of agricultural products safety. At present, the traceability management system based on the development of Internet of Things technology has been widely used in government supervision of agricultural product quality and safety traceability, electronic certification of livestock and poultry diseases, and through the RFID technology, intelligent two-dimensional code, etc. Safety, agricultural security, and agricultural product safety.
3. The application of Internet of Things in the utilization of agricultural resources
Use satellite shake and Internet technology to monitor and collect crop growth, area, estimated yield, quality, and soil and plant protection information in the monitoring area, and process the collected data to achieve planning and monitoring of agricultural production in a specific region. The vigorous development of Internet of Things technology in China in recent years is inseparable from the development of GIS systems and GPS systems. The coordinated operation of GIS and GPS, collecting and collating information, and using WiFi wireless technology for information processing and transmission have realized the overall planning of agriculture. GPS is the global positioning system using satellite sensing for information positioning. The farmland used by intelligent agricultural technology collects the necessary information through GPS technology and transmits it to the processor for information processing. It can not only understand the distribution and implication of water, soil and fertilizer beneficial to farmland, but also provide early warning for crop growth and plant diseases and insect pests in the monitoring area, providing a scientific basis for agricultural sector production decision-making.
4. The application of Internet of Things in the e-commerce of agricultural products
The docking agricultural Internet of Things platform is the future development direction of agricultural products and e-commerce, which is the biggest highlight of the difference between e-commerce providers such as Taobao and Jingdong. The application of the Internet of Things technology can not only realize the agricultural product introduction and online transaction functions, but also trace the source of the whole process of agricultural product safety production, and further enhance the safety of agricultural products for agricultural products through agricultural production monitoring video and VR real-life experience. Trust and purchase desire, and then cultivate high-end consumer groups to increase the income of agricultural producers, and achieve high-quality agricultural products really "sell well."
In accordance with the "Internet + Agriculture" development concept, the process of smart agriculture construction is accelerating, and the Yiwu Internet of Things has also continuously strengthened the application development based on Internet of Things technology. By coordinating the operation of WiFi technology, RFID technology and sensor network technology, Yiyi Internet of Things ensures the accurate operation of Internet of Things technology in smart agriculture, and promotes the fine management of agricultural production and the traceability of agricultural products. Although at present, there are still some unsolved technologies and application problems in the Internet of Things technology, with the development of the times and the progress of the industry, these problems will surely be solved. The Internet of Things technology will promote the rapid development of China's smart agriculture!
