Abstract: | Along with the constant improvement regarding the level of information in China as well as the continuous de -velopment of Mechanic automation , computer controlling system and measurement industry .The intelligence control has been applied extensively in agricultural production ,industrial manufacturing , advanced study and the like .Consequently , the seeder's malfunction collection and processing system is designed and created on the basis of STM 32 microprocessor . With the STM32 serving as the fundamental part , the system's hardware primarily include information collection , interac-tion between users and machine , intelligence control , alarming , auto-compensation ,motor drive and so forth , which per-form functions such as collecting , analyzing , processing and controlling the data of sensor node .The software of the sys-tem chiefly incorporate four subroutines known as speed status ,seeding rate , judgement of miss-seeding , the detection of opener's blocking and vacant seed case .The results of experiment indicate that the selected TAP-40 LS40 N1-D3 is able to detect the seed flow ,vacant seed case as well as the blocking of seed tubes .The accuracy rate of miss-seeding alarm reaches more than 97% under certain interference environment , which achieves the precise malfunction collection of the seeder .Furthermore , the system possesses high stability with low error rate , which means a wide application prospect for it. |
