奶牛体温无线收发数据采集系统的设计与实现

Design and Realization of a Wireless Data Collection System for Milk-cow Body Temperature

定时采集奶牛体温对于发病奶牛的诊断、及时治疗有着重要的意义。为此,介绍了基于无线收发芯片nRF403实现PC机与多台STC51单片机系统的无线数据通信,在此基础上选用了高精度的一线式温度传感器DS18B20组成了奶牛体温无线数据采集系统,并给出了系统硬件和软件的设计。该系统结构简单,易于实现,可靠性较高,且功能易于扩展。系统的应用能够对奶牛的体温进行定时、连续、无损伤、精确地测量和记录。

A data collection system based on the wireless transceiver chip nRF403 was introduced to gather body temperature of the milk cows. PC was used as the main controller of the system and a single - chip microcomputer STCS1, the terminal. The collected data were transmitted wirelessly to personal computer through serial port to carry out data gathering and processing. By setting the communication model for nRF403 with STC51, the transmission of digital signals can easily be realized, so that the data can be gathered and processed systematically, contimiously and accurately.
