基于STM32和OneNet云平台的奶牛计步器系统设计

Design of cow pedometer system based on STM32 and OneNet cloud platform

奶牛活动量的及时准确监测对奶牛发情检测具有重要意义,为了实现奶牛活动量的无线远距离实时监测,设计一种基于STM32和OneNet云平台的奶牛计步器系统。系统采用STM32单片机作为主控制器,基于ADXL345加速度传感器来实时检测奶牛运动状况,同时利用ESP8266 WIFI实现活动量数据到OneNet云平台的传输。并通过LabVIEW开发奶牛计步器上位机监控系统,实现奶牛活动量的实时监视功能。测试结果表明:系统安装方便,实时性好,对奶牛活动计步的准确率可达97%以上,能够实现奶牛活动量的无线远程监测,及时有效地对发情状态的奶牛进行干预,对奶牛养殖的信息化和智能化具有一定的应用价值。

Timely and accurate monitoring of cow activity is of great significance for cow estrus detection.In order to realize wireless remote real-time monitoring of cow activity,a cow pedometer system based on the STM32 and OneNet cloud platform is designed.The system uses the STM32 single-chip microcomputer as the main controller and an ADXLl345 acceleration sensor to detect the movement of dairy cows in real-time.At the same time,ESP8266 WIFI is used to realize the transmission of activity data to the OneNet cloud platform.The upper computer monitoring system of the cow pedometer is developed through LabVIEW to realize the real-time monitoring function of cow activity.The test results show that the system has the advantages of convenient installation and good real-time performance.The accuracy of step counting for dairy cows can reach more than 97%.It can realize the wireless remote monitoring of cow activity timely and effectively intervene the cows in the estrous state and has a certain application value for the informatization and intelligence of cow breeding.
