Description
Technical field
The present invention relates to unmanned air vehicle technique field, particularly relate to a kind of plant protection unmanned plane.
Background technology
In China cereal crops production process, plant protection is still based on craft, semi-mechanized operation.In agricultural production, the substantial amounts of agricultural plant protection operation of annual needs, the labour that plant protection operation puts into is many, labor intensity big, and dispenser personnel's poisoning happens occasionally, and China's annual pesticide intoxication number has the crowd of 100,000, fatality rate about 20%.The number of dying of illness that pesticide residues and pollution cause also is a surprising numeral.According to statistics, China is every year because preventing and treating not in time, and the cereal crops production loss that pest and disease damage causes reaches more than 10%.Application agricultural aviation plant protection technology to improve the Crop in China prevention and control of plant diseases, pest control Mechanization Level, strengthen agricultural the ability to ward off risks, ensure national food security, ecological safety, realize agricultural sustainable development tool be of great significance.
Relative to traditional agricultural plant protection machinery; unmanned plane has obvious advantage: (1) unmanned plane aloft flies; will not leave behind rut print and damage crops; it is particularly suitable for the Oryza sativa L. that ground installation cannot be walked; the Semen Maydis Caulis Sacchari sinensis of middle and late stage; mountain region forestry and crop, and the prevention and control of plant diseases, pest control of forest vegetation；(2) unmanned plane can hovering, VTOL, need landing site little, can be in field landing, landing is flexible, is particularly well-suited to the national conditions that Chinese soil concentration degree is the highest；(3) dispenser personnel shake control operation dispenser, away from dispenser environment, it is to avoid the health hazard that close contact pesticide causes；(4) there is GPS navigation system, it is possible to automatically plan course line, autonomous by airline operation can independently relay (after i.e. disconnected medicine of building up one's health by taking tonic, start continuous spray from disconnected snack made with traditional Chinese medicines), it is possible to reduce the phenomenon that manually drain spray is resprayed, lifting dispenser quality；(5) operation height is low, can press close to crop 2～3 meters, the air-flow that the huge spin that rotor is downward in addition produces, and pesticide spray is strong to crop penetration power from top to bottom, and drift is few, high-efficiency environment friendly；(6) electronic unmanned plane spray application uses spray mode at least can save the Pesticide use amount of 50%, saves the water consumption of 90%, and this will reduce resources costs significantly；(7), compared with electronic unmanned plane moves with oil, overall dimensions is little, lightweight, and allowance for depreciation is lower, fundamental operation cost of labor is the highest, easily maintains.Therefore the appearance of plant protection unmanned plane substantially increases production efficiency, has saved human and material resources, and plant protection unmanned plane has become rural holding intensive management reinforcement, effective solution route of labour force's day by day shortage problem.Agricultural aviation plant protection is the inexorable trend of agricultural modernization development.But traditional agricultural plant protection unmanned plane, by flying platform (fixed-wing, single rotor, many rotors), GPS flies control, spraying mechanism three part forms, and flies control by ground remote control or GPS, realizes spraying operation；Spraying mechanism includes spray bars, shower nozzle, water pump and medicine-chest；Medicine-chest is suspended on the lower section of flying platform or is fixed on flying platform, and the adjustment of flight attitude can cause medicine-chest inner liquid medicine constantly to rock, and in turn results in the instability of unmanned plane during flying, can cause air crash time serious.Additionally due to unmanned plane is relatively remote owing to flying when operation, observes by the naked eye and be difficult to see clear liquid medicine surplus, it is impossible to understand the surplus of medicine-chest inner liquid medicine, the impact understanding to dispenser process in real time.Do not meet people to automatization, the requirement of intelligent plant protection unmanned plane.
