With the widespread use of the Internet of Things, the Internet of Things for Agricultural Applications will become the mainstream of future agricultural development and will subvert the traditional agriculture and open up the development of new agriculture under the Internet of Things era. Compared with the traditional methods of agricultural production, the Internet of Things not only brings about the change of production technology, but also applies the production information to the development of agriculture in a timely manner, which will promote the development of agriculture in our country.
Today, the development trend of the Internet of Things is already the mainstream. The development of agriculture requires the Internet of things. This is the trend that agricultural development gives to the development of the times. The transformation of agriculture is no longer a traditional manual work. Instead, a large amount of intelligent machinery and equipment will be put into operation as future agricultural production The main way.
In Tianjin, the production of agro-industry internet of things has made a very good reflection. Multi-functional sensor in the grape greenhouse is a weapon for agricultural production, professionals said: "Grape greenhouse the most labor-intensive, IoT equipment installed, the previous one up to manage two greenhouses, and now you can easily control to 5. Take the volume For curtains, it used to be laborious and painstakingly carried out manually, one by one, and it is now possible to do a little mouse click.
In the cooperative control room, energy-saving greenhouse inside the real-time display on the computer screen, a dynamic picture of the record 24-hour shed air temperature and humidity, soil moisture and other information. Once needed, irrigation and other operations can be performed automatically. Gu Jing's cooperative is a demonstration site of the Agricultural Internet of Things of the Ministry of Agriculture with a total of nearly 600 greenhouses. At present, nearly 20% of the affiliates use the Internet of Things, and he intends to expand the scale.
Zhang Hecheng, director of the Marketing Department of the Ministry of Agriculture, said that the Internet and the Internet of Things have achieved remarkable success in agriculture. A number of mature business models have emerged. More effective measures should be taken to make them a new impetus to modern agriculture.
The emergence of Internet of things, for the implementation of precision agricultural operations process, the collection of farmland environment information requires more accurate and timely. The use of technical means makes agricultural production more and more advanced, and the construction of modern agriculture is gradually started.
GPS provides hyper-localized information
Each time at least 3 orbiting satellites can participate in calculating your distance, helping GPS provide you with precise location information anywhere on Earth. As a result, agricultural machines equipped with GPS receivers are able to identify their location on the farm, mediate operations to maximize productivity or efficiency at this location.
Take soil fertilization as an example. Farmers can use GPS receivers to identify preselected farmland and collect their soil samples. Then the samples were analyzed experimentally and GIS map was established. In essence, this is a computer database program. Using this type of map, farmers can accurately determine the amount of fertilizer applied to each sampled farmland. Variable-technology (VRT) fertilizers precisely spray the fertilizer needed in the field. This process is an example of "precision agriculture."
Information, Analysis and Tools
Precision Agriculture requires success in three areas. It requires specific location information, such as soil-fertility maps; it requires understanding of location-specific information and the ability to make decisions; making decisions often requires computer-aided modeling, which requires mathematical and statistical analysis of soil fertility and Variable relationship between crop yields.
In the end, farmers must have the physical tools to make management decisions. For example, a variable-technology fertilizer applicator equipped with a GPS system automatically adjusts the amount of fertilizer applied to each farmland. Other examples of "precision agriculture" include applying different seeding rates depending on the type of soil; using sensors to identify weeds, diseases or pests for the most appropriate insecticide to use.
The role of location-specific information In addition to helping map soil conditions and increasing yields, satellite images can be used to show crop health. Now, drone can collect highly-clear photos of crops and farmland. These photos are analyzed by computer to show different reflected light, according to which scientists can understand crop health and soil types. For example, healthy crops in the picture show a clear bright color while diseased crops show a dark color, which can be used to determine the presence of cotton root rot. In the future, farmers may simply need to treat the affected area. UAVs also include the advantages of low cost and clear picture details, but the legitimacy of their use in agriculture is still under discussion.
automation
Automated navigation, or GPS-based system, guides the tractor to work in more accurate mode than even human action. Currently, safety concerns completely limit the unmanned potential of smaller machines. Fully automated or robotic farming machinery has begun to appear on a high-margin agriculture on a small scale, such as grapes, nursery crops, certain fruits and vegetables.
Automechanics can replace humans and accomplish more tedious tasks, such as harvesting vegetables by hand. They use sensing technology, including mechanical vision, detectable locations, stem and leaf size and other information, and then notify the machine during the job. Japan has become a leader in this area. Japanese agriculture is often divided into smaller plots, and the country is also a robot technology leader in the world. But automakers are also emerging in the United States, especially in California, where many specialty crops are produced in the United States.
The development of flying robots will result in the replacement of most human-operated drones today, with mechanical vision and hands-on pliers. Many reconnaissance missions, such as pests and diseases, require people to go far, obtain the leaves representing the plants, and then repeatedly see if they are pests and diseases. Researchers are developing a technology that can make use of flying robots to perform these tasks without human involvement.
Breeding + sensor + robot
High-throughput plant phenotype (HTPP) is a futuristic "precision agriculture" technology that is a combination of genetics, sensors and robots. It can be used to develop new crop varieties or increase crop nutrient content, drought tolerance and pest and disease resistance. HTPP technology uses multiple sensors to measure important plant physical data such as height, number of leaves, size, shape, angle, color, degree of wilt, stem thickness, number of results, and the like. These are phenotypic features and are also physical representations of plant genetic code. Scientists can compare these data with known genetic data for a particular plant.
Coupled with sensors, scientists can obtain phenotypic characteristics of thousands of species very quickly, and breeders and geneticists can determine which species will be excluded and which can be further tested, which will greatly accelerate crop improvement The process.
In the future, the development of agricultural Internet of Things will be more scientific, intelligent and digital.
The production of agriculture needs to adapt to the development of the times. In our country, the development of the Internet of Things has accelerated the change of the mode of agricultural production. The constant innovation of technology promotes the development of agriculture. The technology of Internet of Things has triggered a new round of agricultural development opportunities and mastering things technology, which is the key to the development of modern agriculture. In all intelligent today, the development of agriculture will carry the wings of science and technology, flying higher and higher.
