【摘要】：我国作为一个农业大国,农作物的产量对我国的可持续发展起到了基石的作用,喷洒农药作为防治病虫害的最重要措施之一,对农作物的健康生长起着至关重要的作用。目前,大部分喷洒装备仍依赖人工的现场操作,自动化、智能化程度低;由于在喷洒作业过程中,周围环境常伴随着农业药品挥发物,严重危害作业人员的身体健康;现有大部分喷洒机械作业都采用无差别喷洒,造成了严重的浪费,并且加重了对环境的污染。为了提高农业机械的智能水平,本课题提出了一种具有闭环控制、高自动化的智能喷洒机器人系统方案,并设计了一款无人驾驶的智能喷洒机器人系统。本课题主要针对国内喷洒机械普遍存在精度低、污染大、智能化低、整机不稳定等问题,进行有针对性的改良和创新设计,采用传感器技术、精准的喷洒技术、组态技术和可编程控制器技术等相结合的控制方法,研制的智能喷洒机器人,可实现在复杂多变的田间环境稳定工作,并对作物病虫害能实现精确定位、精准喷洒,可大幅提高农民的工作效率,降低生产成本,减少了环境污染物的使用,改善了作业者的工作环境,加强了对身体健康的保护。经试验测试,喷洒效率提高2~3倍;同国内外同类机械相比,价格为国外同类产品的1/4~1/3,待技术成熟后可在其他领域应用,不仅能大幅提高喷洒机械智能化水平、降低能耗、减少人工成本,而且可促进我国农机领域的技术水平的提升,该课题具有非常好的经济效益和应用前景。
[Abstract]:As a large agricultural country, crop yield plays a cornerstone role in the sustainable development of our country. As one of the most important measures to control diseases and insect pests, spraying pesticide plays an important role in the healthy growth of crops.At present, most spraying equipment still rely on artificial field operation, automation, low degree of intelligence, because in the spraying process, the surrounding environment is often accompanied by agricultural drug volatiles, seriously endangering the health of workers.Most of the existing spraying machinery uses indiscriminately spraying, which causes serious waste and exacerbates the pollution to the environment.In order to improve the intelligence level of agricultural machinery, a scheme of intelligent spraying robot system with closed loop control and high automation is proposed in this paper, and an unmanned intelligent spraying robot system is designed.Aiming at the problems of low precision, high pollution, low intelligence, unstable whole machine and so on in the domestic spraying machinery, this subject mainly carries on the targeted improvement and the innovation design, adopts the sensor technology, the precise spraying technology,The intelligent spraying robot developed by the combination of configuration technology and programmable controller technology can work stably in the complex and changeable field environment, and can realize accurate positioning and accurate spraying of crop pests and diseases.It can greatly improve the working efficiency of farmers, reduce production costs, reduce the use of environmental pollutants, improve the working environment of operators, and strengthen the protection of health.The test results show that the spraying efficiency is three times higher than that of similar machinery at home and abroad, and the price is 1 / 4 / 1 / 3 of that of similar products from abroad. When the technology is mature, it can be applied in other fields, not only can the intelligent level of spraying machinery be greatly improved, but also energy consumption can be reduced.It can reduce the labor cost and promote the improvement of the technical level in the field of agricultural machinery in China. This subject has a very good economic benefit and application prospect.
