摘 要：本文中笔者基于MSP430低功耗单片机控制的奶牛生理状态监测系统对奶牛生理状态监测原理、2.4G无线模块做星状网络、GPRS模块数据上传方案等进行详细的说明。经实践可知此系统具有低成本、高精度等特点，在NRF24L012.4G模块的应用方面具有创新性。该系统在对奶牛生理状态监测时，既关注奶牛的健康状况，又着重监测奶牛的妊娠期，并将数据无线发送到工作人员的手机客户端和办公显示屏上，从而可以在一定程度上减轻奶牛场工作人员的工作量，提高奶牛妊娠期的监测效率，扩大奶牛场的经济效益。

Abstract：In this paper，the physiological state monitoring system of dairy cows based on MSP430 low-power microcontroller is used to monitor the physiological status of dairy cows、2.4G wireless module makes star network，GPRS module data uploading scheme and so on. According to the practice，this system has the characteristics of low cost and high accuracy，and it has an innovative application in the application of NRF24L012. When the cows physiological status monitoring，this system is focused on the health of the dairy cow and focus on monitoring the cow's pregnancy，and the data are sent to the staff's mobile APP and office display screen，which can reduce the workload of the dairy farm workers to a certain extent，improve the monitoring efficiency of the cow's pregnancy and expand the economic benefits of the dairy farm.

Keywords：MSP430；GPRS；NRF24L01；wireless communication；pregnancy

牛奶是生活中必不可少的營养品，提高奶牛牛奶的产量成为商家比较关注的问题。影响奶牛产奶量的关键因素有两个：一是奶牛的生理状况是否健康，二是饲养员能否较为准确的判断奶牛的发情期。目前，对奶牛的发情期判断一般还是由人工来进行，效率较低。若是能利用物联网技术通过计算机判断发情期，并对奶牛的生理状况进行检测和提醒，可以提高工作效率，在一定程度上提高产量，同时也减少工厂工人的数量，为工厂节约成本。本文中笔者设计的奶牛生理状态检测系统，可对每头奶牛的生理状况进行实时检测，并对发情期做出较准确的判断。然后通过2.4G无线模块发送到上位机做提醒和处理，使工作人员能够及时发现奶牛的异常，并及时验证和处理。……
