【摘要】 研制了奶牛个体识别及信息采集系统,实现奶牛的精细养殖、科学管理,不仅有利于提高牛奶的产量和质量,而且能够时时监测奶牛的健康状况,利于及早进行疾病预防;系统由上位机、信息传输卡和个体识别及信息采集卡三部分组成,其中个体识别及信息采集卡是整个系统设计的关键,超低功耗是奶牛个体识别及信息采集卡设计的主要优化目标,设计中采取了多种方法以降低卡的功耗;在硬件方面,选用了超低功耗器件及带休眠模式的低功耗元器件;软件方面,通过软件设置使元器件尽量处于低功耗休眠状态,并利用单片机中断系统的特点,使各种外部事件都在中断处理程序中完成,经过现场大量试验,系统工作正常,各项指标均达到了设计要求。更多还原

【Abstract】 A cow’s individual identification and information collection system is designed.With it the cow could be breed precisely and managed scientifically.This not only improved the amount and quality of the milk but also helped to judge weather the cow was ill,so disease could be treated in time.The system is comprised of superior-computer,information transmission card and individual identification and information collection card.The cow’s individual identification and information collection card is the key for the system and low power consumption is the primary optimized target for it.Many measures were taken to reduce power consumed by the card.Super-low power consumed components and components with dormancy mode are used on the design of hardware.The components with dormancy mode were set into low power mode as soon as possible by software.All exterior functions are realized in the interrupt subprogram with the excellence of the microcomputer interrupt system.The system performed well on the cattle farm in the test and all of the design target is realized..更多还原
