In recent years, with the development of smart agriculture and precision agriculture , the application of IoT technologies such as smart sensing chips and mobile embedded systems in modern agriculture has gradually expanded. In monitoring crop irrigation, soil air changes, environmental conditions of livestock and poultry, and large-scale surface inspections, collect temperature, humidity, wind, atmosphere, rainfall, related land humidity, nitrogen concentration, and soil pH . Networked technologies are playing an increasingly important role, thereby achieving scientific monitoring and scientific planting, helping farmers to resist and reduce disasters, and improving overall agricultural benefits.
1. Environmental information and animal and plant information monitoring
By arranging a multi-level IoT sensor network detection system, observation and research on the living habits, environment, physiological conditions and population complexity of livestock and poultry, aquaculture , and rare animals can also be used to monitor the forest environment and fire alarm (normal nodes It is randomly scattered in the forest, and the environmental data is regularly reported under normal conditions. When a fire occurs, the nodes will send the specific address of the fire source and the size of the fire to the relevant departments within a short time through cooperation. It can also be used in precision agriculture to monitor pests in crops, soil pH and fertilization.
2. Information collection in a greenhouse environment
In a greenhouse environment, a single greenhouse can become a measurement and control area of a wireless sensor network . Different sensor nodes are used to form a wireless network to measure soil humidity, soil composition, pH value, precipitation, temperature, air humidity and pressure, light intensity, and CO2. Concentration, etc. to obtain the best conditions for crop growth. At the same time, biological information acquisition methods are applied to wireless sensor nodes to provide a scientific basis for precise greenhouse regulation, so as to increase crop yield, improve quality, regulate growth cycles, and improve economic benefits.
3. Water-saving irrigation in precision agriculture
The wireless sensor network automatic irrigation system uses sensors to sense the soil moisture and communicates with the receiver under the set conditions to control the valve of the irrigation system to open and close, thereby achieving the purpose of automatic water-saving irrigation. Due to the characteristics of sensor network information transfer, self-organizing network, and real-time communication, the area and number of nodes in the irrigation area are not limited. Rotational irrigation groups can be flexibly increased and decreased. In addition, the nodes can measure and collect devices such as soil, plants, and weather. Build an efficient, low-energy, low-input, multifunctional agricultural water-saving irrigation platform. It can realize the quantification, standardization, modelling, and integration of agricultural and ecological water-saving technologies in greenhouses, courtyard gardens, green belts, highway isolation belts, and farmland irrigation areas, and promote the rapid and healthy development of water-saving agriculture .
4. In terms of large-scale production of farmland, orchards, etc.
How to use the Internet of Things technology to real-time obtain and transmit the information of the temperature, humidity, light, rainfall, etc. of the small agricultural environment, the organic matter content of the soil, temperature and humidity , heavy metal content, PH value, and plant growth characteristics. For science, Fertilization and irrigation are of great significance, which has become one of the most important topics in the research field of agricultural Internet of Things .
5. In terms of circulation of fresh produce
The temperature of the storage and transportation environment and the moisture of agricultural products need to be controlled. If the ambient temperature is too high, a large number of agricultural products may rot, and the quality of insufficient water will be affected. In this link, the help of the Internet of Things will greatly improve the transportation of agricultural products Quality. At present, Korea, the European Union and other countries and regions have developed operable IoT application models in this area, and China's research in this area needs to be strengthened urgently.
