Design Of The Intelligent Spraying System Controller Based On DSP

China is a large agricultural country. Therefore, it's important to do well in modernization of agriculture. Along with the acceleration of our country's modernization, agriculture modernization has is also gradually developing. Agricultural modernization is a process to gradually equip agriculture by using modern production methods and technologies. With today's advancement in electronic technology, it is gradually being applied in the agricultural modernization, especially the embedded technology. This paper is based on these ideas, which designs the automatic spraying insecticides as an adaptive controller for a large scale grape growing areas.With the view of inefficient traditional orchard spraying trellised, we designed an intelligent spraying system controller using a combination of modern embedded systems and multi-sensor signal fusion technology to solve the low efficiency spraying process, drug waste and environmental pollution of traditional type. The intelligent spraying system controller consists of three processor, namely S3C2410 for intelligent control, TMS320DM642 for image acquisition and processing and TMS320F2806 for multi-sensor signal acquisition integration. These processors are combined together with different protocols, thus controlling the real time intelligent movement of the machine for automatically spraying the trellised type crops.This article start from the present situation of domestic and foreign trellised type crops spraying system, firstly introduces the intelligent of trellised type spraying system controller of significance and embedded systems used in agriculture of advantages, overall introduction of this intelligent system constructability. Secondly, introduces the visual processing technology based on TMS320DM642 in hardware platform and the algorithm of grape leaves sparse degrees extraction realization. Presents the multi-channel sensor signal collection and processing, and to illustrate the driver circuit design. Finally, does a detailed discussion about the communication protocols and adaptive type control method of whole system. At the end of the article also puts forward a more constructive conclusions and recommendations for this system.
