【摘要】 为加强奶牛活动量的监测,设计了一种无线数据传输的低功耗计步器。单片机选用高性能的AT-MEGA32,无线发射模块选用NRF24E1芯片,上位机采用了LABVIEW编程,系统平时工作在休眠状态,数据的采集和传输通过软件中断请求进行处理。实验结果表明,该系统能够提供可靠的奶牛活动量数据,并且系统模块集成度高、结构简单、功耗低、工作稳定可靠,适合推广应用。更多还原

【Abstract】 In order to strengthen the monitoring activities of dairy cattle,this paper designed a wireless data transmission of low-power pedometer.SCM has selected high-performance ATMEGA32,wireless transmitter module has selected NRF24E1 chips,supervisory computer software was programed using LABVIEW,data collection and transmission through software interrupt,system usually in the dormant.experiment result has showed that the system can provide reliable data of cattle activities,systems integration,simple structure,low power consumption,stable and reliable work etc,so it is worthy to spread the application.更多还原
