摘要
根据奶牛发情期活动量明显增加的特点,设计了奶牛计步器来采集奶牛的活动信息,计步器采集信息后通过无线传输的形式传输给上位管理机进行分析处理,帮助奶农监测奶牛的发情期以便于奶牛及时受孕。低功耗是计步器设计的关键,采取了多种措施来降低系统功耗。计步器的微处理器和无线通信模块平时置于低功耗模式,信息采集与无线通信是通过中断方式实现的,振荡电路辅助通信模块完成无线信息传输。通过实验室及奶牛场现场实验,计步器计数正确率在99%以上。
A step counter for collecting cow activity information is designed to detect cow oestrus because cow increases movements obviously in oestrus period. The information collected is transmitted to upper computer management system by wireless transmission. With the assistant of step counter, cow administrators can judge whether cow is in oestrus period in time. Low power consumed is the key for design the step counter and many measures are taken to reduce power consumed. The microprocessor and wireless communication module are initialized in low power consumed mode. The information collecting and wireless communication are realized by interrupt mode. Many experiments are done to test the reliability and veracity in the library and cattle farm, the veracity rate of the counter steps is up to 99%.
