What links have the Beidou system of hard core technology been applied in the field? What processes have been saved?

Science and technology have been progressing, and China agriculture has entered the development track of intelligent management and precise implementation. The construction and application of intelligent agricultural machinery and equipment is an important part of intelligent precision agriculture and the most direct means to ensure food safety production. As a key technology in the intelligent technology of agricultural machinery, Beidou satellite navigation technology has been applied to agricultural production links such as farming, planting, management and harvesting, and achieved good results in production practice.

The application of Beidou navigation system in agriculture includes tractor automatic navigation and driving system, agricultural machinery autonomous operation system and UAV plant protection system. The autonomous operation of agricultural machinery is applied to ridge cultivation, harvesting, straw returning and other fields. Take combine harvester as an example, combine that data collected by Beidou system and geographic information system, the farmland is digitized and partitioned, so as to draw the output map of crop distribution, and how to control the movement and cutting length of combine harvester according to the output rate, and manipulate the harvest rate, threshing rate and feeding rate to achieve the best harvest and harvest efficiency; Analyze the increase and decrease of the output of the control center and optimize the field input. Similarly, through the division of cultivated land area and the setting of parameters such as row spacing, rice transplanting can also achieve standardized planting, with high accuracy and good planting effect.

The unmanned plant protection aircraft equipped with Beidou navigation system has higher remote control reliability and has achieved comprehensive coverage in signal blind areas, especially in remote mountainous areas. Beidou navigation system combines hyperspectral image processing technology, geographic information system and other technologies to comprehensively monitor diseases and pests, analyze the specific location and severity of diseases and pests, plan flight routes and flight areas, and accurately apply pesticides. In addition, some studies show that the system can also make the plane reach the exact position where it stopped spraying for the last time, so as to ensure that it does not repeat spraying and does not miss the area.

The application of Beidou navigation system in the field of agricultural mechanization in China will change the traditional operation mode and accelerate the transformation of agricultural development mode. It is an important seed industry practice, with good social value and economic benefits, leading the transformation and upgrading of agricultural machinery in China, pointing out the direction for the informationization and intelligence of agricultural machinery operation, and having broad industrial prospects.
