The Agricultural Internet of Things (Digital Agriculture ) is a new type of intelligent agricultural model based on agricultural big data . Through the accumulation and use of big data , the digitalization, precision and intelligence of agricultural production can be realized. The agricultural Internet of Things has several key levels: the collection of front-end production information, the transmission of information, and the processing and application of information. Use sensors to collect information during production such as soil, weather, pests and diseases, agricultural operations, etc., and transfer the information to a cloud platform for data analysis through the cloud platform to provide data support for production management, quality traceability, agricultural technology services, etc. Main applications in agriculture.
Real-time data monitoring of agricultural planting and transmission of sensing data are the basis of precision agriculture and smart agriculture . Low-cost and easy-to-use IoT wireless sensing equipment and wireless control equipment are the keys to the precision agriculture and smart agriculture's widespread application and popularization. However, understanding the agricultural Internet of Things technology and learning to apply related sensing and control equipment are the prerequisites for all realization.
Whether it is the traditional planting industry or the modern Internet of Things planting, watering, fertilization, and pesticides are indispensable. Farming is based on experience and feeling. Farming in the field and passing these experiences and methods from generation to generation, people use this. Methods Complete the cultivation of previous agricultural products. However, should the fruits and vegetables be watered, fertilized and sprayed? How can we maintain the concentration, temperature, humidity, light, and CO2 concentration, and how to implement on-demand supply? In the past, these problems, which were manually handled in the different growth cycles of crops based on experience and sensation, have begun the real-time quantitative "check" in front of the agricultural Internet of Things. The "farming" model created by the Internet of Things has become a new type of agricultural model that makes up for the disadvantages of traditional agriculture . This kind of smart storm started through the Internet of Things technology has enabled farmers to achieve the goals of “environmentally measurable, controllable production, and traceable quality”, ensure the quality and safety of agricultural products , and lead the development of modern agriculture .
Nowadays, there is a temperature and humidity monitoring system ( temperature and humidity control system ). The system uses wireless data transmission technology to realize the collection of agricultural production environment information and remote control of equipment. At the same time, a camera is installed in the field to realize remote monitoring of video; environmental information and video Based on information monitoring, build a production management, storage and transportation and quality traceability system.
The temperature and humidity monitoring system will install temperature and humidity , light, soil temperature and humidity, leaf humidity, carbon dioxide and other sensors in all areas that need to be monitored. The temperature and humidity, light, soil temperature, soil water content, carbon dioxide concentration and Environmental parameters such as leaf surface humidity are collected in real time, and wireless data transmission is used to send the temperature and humidity information in the facility to the central control room in real time. Automatically turn on or off the specified equipment (such as remote control of irrigation, opening and closing of roller shutters, etc.). When the collected data exceeds the preset limit of the system, the system alarm function will be turned on, and a short message will be sent to inform the relevant management personnel to facilitate the management of crop production.
At the same time, cameras and other monitoring equipment are arranged on the scene of the greenhouse to collect video signals in real time. All image information is summarized to the main control room through the LAN of the park, unified control and management, and remote access to image information can be achieved; the administrator can observe the situation of the scene, view data such as temperature and humidity on the scene, and control remotely through a computer or smartphone. Intelligent adjustment of specified equipment. Video surveillance is responsible for collecting audio and video information of key production links and important circulation links in the plantation park.
Intelligent monitoring system for field soil information. Small and medium-sized automatic weather stations can automatically monitor meteorological information such as air temperature and humidity, wind speed and direction, rainfall and solar radiation. The same soil profile has 4 depths (surface soil layer, core soil layer, subsoil layer, and incubation layer). ) Humidity and volume moisture content.
The equipment remote control system is mainly composed of control equipment and corresponding relay control circuits. Through the relay, various agricultural production equipment can be freely controlled, including water spray systems such as sprinklers and drip irrigation, and air conditioning systems such as roller shutters and fans. The administrator can directly control the device through the computer and mobile terminal to complete the daily work.
Today's Internet of Things system has fully demonstrated the power of the agricultural product traceability system. Advanced markets rely on the agricultural product traceability system to check the product quality of agricultural products, manage various parameters and indicators of agricultural products cultivation, and record all links in production. system. Finally, the product information is output in the form of a barcode or a two-dimensional code. The middle entry record will be displayed after scanning the barcode. Once a product has a problem, it can be traced back to every detail of the processing process, which also enables consumers to trace back to each stage of agricultural product production and make purchases more assured.
