At present, there are fewer and fewer people in rural areas and fewer people engaged in agricultural activities, and they are generally older. Most young people go to work in big cities and rarely engage in agricultural production. This will lead to a decline in productivity in rural areas. Of course, if we want to solve this problem fundamentally, we must increase productivity and change the original inherent production methods, so that fewer manpower can create great value.
The realization of unmanned farms relies on three major technologies. "Biotechnology, Internet of Things technology, cloud computing technology.", "In terms of intelligent agricultural machinery and information technology, it mainly relies on the Beidou navigation and positioning system and 5G communication system."
In the Wisdom Farm demonstration, we can see that the parking position of the grain truck was a bit ahead during the third grain unloading, and the harvester was reminded by information. This is the result of the coordinated operation of the Beidou navigation and positioning system and the communication system to achieve precise navigation and precise operation of multiple agricultural machinery. He said that the Beidou navigation and positioning system mainly provides precise positioning. The Internet of Things communication system processes a large amount of information in real time and the information transmission speed is fast. At present, the unmanned agricultural machine has a high accuracy of linear walking.
At present, the Beidou-based smart agriculture results developed by the team have generally reached the international advanced level. Among them, paddy field automatic navigation operation and master-slave navigation technology are at the international leading level, meeting the precise operations of dry land and paddy field cultivation, planting, plant protection and harvesting. Need to break the monopoly of foreign technology and provide important support for my country's modern agricultural smart production.
For the question of when unmanned farms can be promoted on a large scale, two major conditions are needed. "First, the infrastructure must be good, and the water network, road network, power grid, and communication signal of farmland must meet certain conditions; second, the plot of land must be large, and the small and scattered land must be effectively integrated." Experiment and demonstration are the main focus, and then gradually promoted.
Our team has confirmed preliminary cooperation intentions in many places, and plans to experiment and plant various crops. There is still a long way to go for the comprehensive application of smart agriculture. First, we must improve the collection of agricultural data. This is inseparable from a large number of experiments and precise IOT system collaboration, which will lay a solid foundation for future promotion.
