[ China Agricultural Machinery Industry News ] In recent years, the development of plant protection drones has undoubtedly opened a good start for the development of unmanned agricultural machinery. Many cooperative directors, large grain farmers and farmers have expressed their approval for plant protection drones. It has shown great interest in other unmanned agricultural machinery and equipment. At present, with the accelerating process of rural land circulation and the shortage of rural labor, the mechanization of unmanned agricultural production is the general trend. However, there is still a long process of research and development and large-area application of unmanned agricultural machinery technology. The author believes that the industry should focus on the following three aspects to carry out research and promotion.
There is a long road to promotion of unmanned agricultural machinery. It is necessary to make great efforts in three aspects.
First, increase state subsidies and guide key areas and demonstration cooperatives to promote their applications.
How can intelligent and advanced agricultural machinery be highly recognized and accepted by users as soon as possible? How can I quickly move to a market with high demand? How to better match good technology and products with user needs? It is important and effective to use guiding policy support and increase the corresponding state subsidies.
The National Conference on Agricultural Mechanization held at the beginning of the year revealed that this year, the open subsidy policy will continue to be implemented. Plant protection drones will be included in the scope of national agricultural machinery subsidies, and plant subsidies for plant protection unmanned aircraft will be allowed in suitable areas. The pilot areas will be promoted from important agricultural provinces and cities. And gradually promoted to the whole country. At present, Henan, Shandong, Jiangsu, Hubei and other places have gradually included plant protection drones into the local subsidy category, but the specific subsidy catalogue has not been announced. Although the state has introduced support policies for plant protection drones, the subsidy needs to be continuously increased. The support and promotion policies for other unmanned agricultural machinery must be put on the agenda as soon as possible.
It is understood that the unmanned agricultural machinery automatic driving system can be used for agricultural machinery operations such as land ploughing, hoeing, rotary tilling, ridge, sowing, spraying, harvesting, etc., which is greatly improved than manual labor, and is an important aspect of realizing agriculture. The research and development and promotion of unmanned agricultural machinery technology will inevitably bring about earth-shaking changes for farmers' life, agricultural machinery industry and agricultural development. However, due to the high cost of this system, if the cooperatives or farmers who have the intention to purchase the unmanned agricultural machinery can obtain certain subsidy funds, if these intelligent unmanned agricultural machinery and equipment can enter the national subsidy catalog, the unmanned agricultural machinery will be like no one. The machine is used as quickly as it is in the field.
Second, accelerate the key technologies of the key issues and strengthen cooperation between science and technology.
The unmanned agricultural vehicle uses the satellite positioning and navigation system to remotely command the agricultural machinery to drive automatically. This system combines satellite navigation and automatic control technology with agricultural machinery, adding sensors and controllers to the traditional hydraulic steering system. Command input from the autopilot system can be received. Before the cultivation, the operator inputs the operating parameters such as the area of ​​the cultivation and the thickness of the soil into the navigation system. After receiving the signal, the antenna can guide the agricultural machine into the automatic operation mode through the navigation system, and carry out the cultivation according to the planned route through the electronic control valve group. In addition to tractors, satellite navigation autopilot systems can be applied to large agricultural machines such as planters, harvesters, and plant protection machines. Therefore, vehicle networking equipment, related software services, and hydraulic steering systems have become the key to unmanned agricultural machinery.
The development of core technologies is the key to the development of unmanned agricultural machinery. With the gradual improvement of intelligent vehicle systems, intelligent unmanned agricultural products will be able to comprehensively improve the current agricultural landscape, and will be widely promoted in the future and gain wide recognition. However, compared with well-known foreign brands such as Kubota and Case, the pace of domestic enterprises is relatively backward. This requires cooperation and research between relevant research and development institutions and production enterprises. For domestic agricultural machinery, appropriate reference to foreign intelligent control and remote control. Information technology, apply them to China's agricultural machinery.
Third, according to the characteristics of different regions, the market research and development and development will be carried out step by step.
According to the data of the 2016 China UAV Industry Research Report released by iResearch, the market size of China's agricultural and forestry plant protection drones will reach 20 billion yuan by 2025. Although it was once one of the hot investment track of the high-tech industry in the capital market in 2015, the coverage rate of plant protection drones in China is only 2%, compared with 40% to 50% coverage in Japan. The share of man-machines in China's agricultural industry is actually low.
Then, the market for unmanned agricultural machinery and equipment needs to be further developed, but it cannot be blind. The intelligentization and informationization of agricultural machinery aims to turn agricultural machinery into intelligent networking machinery in the future, and carry out intelligent operations according to different crop varieties, topography and climate. The new agricultural machinery and equipment has become a fully digital device, and the farmers can easily realize the combined action at the push of a button.
This intelligence is a gradual process. Large foreign agricultural machinery brands such as John Deere have reached a certain height in the development of products including automatic driving, remote information monitoring, highly intelligent vehicle control, and even coordinated control of multiple machines. However, the distribution of farmland in China is complicated, with more farmland in the south and more and more land in the north. In response to this situation, the development and promotion of unmanned agricultural machinery should be integrated into intelligence and information, and each machine can achieve local high-level intelligent control and remote networking. To do both at the same time, we have put forward higher requirements for relevant scientific research institutions and enterprises in China, and we need to carry out market research and development and development step by step according to the characteristics of different regions.
