Description

Multi-spray-way controllable spray-amplitude type accurate targeting weeding module based on artificial intelligence

Technical Field

The utility model discloses an it is accurate to target weeding module to spout controllable spray pattern formula more based on artificial intelligence relates to agricultural machine field, automatic control field and artificial intelligence field, specifically is applied to the field intelligence of the multiple crop of agricultural field and weeds.

Background

Grain production is related to national grain safety, but in the agricultural production process, problems of farmland weed damage, excessive pesticide use and the like seriously threaten grain yield and production safety: the farmland weeds compete with crops for resources such as light, heat, water, fertilizer and the like, and the grain yield is influenced. Survey data show that in 2018, the total yield of grains in China reaches 65789 million tons, and because 300 hundred million kilograms of grains are lost due to weed damage, the yield loss of grains caused by weed damage reaches 4.56%. Therefore, in order to overcome the harm of weeds to agricultural production, the existing weeding modes at home and abroad are mainly manual weeding, mechanical weeding, chemical weeding and biological weeding, and research institutions at home and abroad also research laser weeding and current weeding, but the current technology is still not mature. Because of low efficiency and time and labor consumption of manpower weeding, the method is not suitable for the development of modern agriculture. The mechanical weeding efficiency is high, but the seedling injury problem still exists. The biological weeding cost is high, the pertinence is strong, and the problem of various weeds in the field cannot be solved. In the past 50 years, chemical weeding has become an important component of global modern agricultural production, but the chemical weeding adopts a broad-type 'carpet' and 'broad-width' herbicide throwing mode at present, so that serious herbicide resource waste and ecological environment pollution are caused. Excessive pesticide input causes non-point source pollution and continuous environmental deterioration, which not only directly increases the agricultural production cost, but also indirectly increases the environmental management cost. The importance of reducing and controlling the amount of the pesticide on the conversion of agricultural production modes and the promotion of agricultural green development is self-evident. The difference of weed area distribution is completely ignored in the traditional herbicide spraying operation, and the extensive carpet type herbicide putting mode is adopted, so that serious herbicide resource waste and ecological environment pollution are caused. Excessive pesticide input causes non-point source pollution and continuous environmental deterioration, which not only directly increases the agricultural production cost, but also indirectly increases the environmental management cost. The importance of reducing and controlling the amount of the pesticide on the conversion of agricultural production modes and the promotion of agricultural green development is self-evident. The difference of weed area distribution is completely ignored in the traditional herbicide spraying operation, and the extensive carpet type herbicide putting mode is adopted, so that serious herbicide resource waste and ecological environment pollution are caused. Therefore, how to reduce the quantity and improve the efficiency and improve the utilization rate of the liquid medicine become a research hotspot of the current chemical weeding technology, and under the promotion of the policy of 'precision agriculture', along with the rapid development of the artificial intelligence technology, opportunities are brought to the research and application of variable target spraying equipment based on weed identification and detection.
