At present, China's agriculture is in a period of transition from traditional agriculture to modern agriculture . The agricultural Internet of Things will play a unique and important role and also provide unprecedented opportunities for the development of modern agriculture. Using intelligent information management technology to develop modern agriculture has become one of the hotspots of agricultural development in various developed countries today.
What is the Agricultural Internet of Things ? To put it simply, the agricultural Internet of Things is to use the temperature sensor , humidity sensor , pH sensor , light sensor, CO2 sensor and other equipment in the greenhouse control system to detect the temperature, relative humidity, pH value, and light intensity in the environment. Physical parameters such as soil nutrients, CO2 concentration, etc. are displayed in real time through various instruments or participate in automatic control as parameters of automatic control to ensure that crops have a good and suitable growth environment.
As we all know, planting is inseparable from watering, fertilizing, and pesticide application. Farmers cultivate their fields based on experience and feeling. They face the loess and face the earth and cultivate in the fields. These experiences and methods are passed down from generation to generation. Should I water, fertilize, and spray medicine? How can I maintain the concentration, temperature, humidity, light, and CO2 concentration, and how to implement on-demand supply? In the past, these problems, which were handled in the different growth cycles of the crop based on experience and feeling "fuzzy", have begun 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.
The realization of remote control enables planters to monitor and control the environment of multiple greenhouses in the office. The use of wireless network measurement to obtain the conditions for crop growth can provide scientific basis for precise control of the greenhouse, and achieve the objectives of increasing yield, improving quality, regulating the growth cycle, and improving economic benefits.
Judging from the current trend, IoT agriculture is mainly composed of three major information systems.
The agricultural expert intelligent system takes the development and utilization of the intelligent expert system as the guide, analyzes and judges the environmental data such as climate, soil, and water quality, systematically plans the distribution of the park, rationally selects crop varieties, and scientifically guides the ecological rotation.
The agricultural production IoT control system is based on the Internet of Things technology, and uses various wireless sensors to collect real-time information such as light, temperature, humidity and other parameters of agricultural production sites and the growth status of agricultural products to remotely monitor the production environment. After digitally transforming the collected parameters and information, the transmission network platform is aggregated and integrated in real time. The agricultural expert intelligent system is used to perform timing, quantitative, and positioning cloud computing processing in accordance with various indicators for the growth of agricultural products, and remotely control agricultural equipment in a timely manner. It can be turned on or off to realize intelligent and automated agricultural production process.
The organic agricultural product safety traceability system adds RFID electronic tags to the agricultural products themselves or the freight packaging in the production link, and continuously adds and updates information in the transportation, warehousing, and sales links to build an organic agricultural product safety traceability system. Organic agricultural product safety traceability system strengthens the entire process data sharing and transparent management from agricultural production, processing, transportation to sales, etc., realizes the traceability of the entire agricultural product process, improves the management efficiency of agricultural production, promotes the brand building of agricultural products, and improves agricultural products. Added value. Most of the traditional greenhouse data collection work uses manual meter reading or pre-wired wired collection methods. The disadvantages of the manual method are the large workload, high cost, and difficulty to ensure the real-time and validity of the data. Wired data collection has many disadvantages such as high wiring costs and the need to change the line direction and length when the measurement node position changes.
The greenhouse temperature and humidity monitoring system deploys air temperature and humidity sensors , soil temperature sensors , soil moisture sensors, light intensity sensors, CO2 sensors, etc. in each intelligent agricultural greenhouse to collect the corresponding environmental parameters in the greenhouse in real time and on the data server Storage and intelligent analysis and decision-making of real-time monitoring data, and automatically turn on or off designated equipment (such as remote watering, roller shutter, etc.).
In the future agricultural production, the application of the agricultural Internet of Things system will be more extensive. Farmers see the benefits brought by the use of advanced technology, and will actively choose an intelligent system suitable for their own agricultural production to increase the output of agricultural products and increase returns.
