摘要
为了实现奶牛溯源信息高效采集与实时传输,在分析现有技术的基础上,提出一种将射频识别技术与无线传感器网络技术相结合的无缝隙信息采集与传输方法,并对系统方案设计、网络体系架构和通信协议转换等主要内容进行研究,实现并应用于奶牛养殖信息溯源系统。试验结果表明,基于单点通信有障碍35m、无障碍75m范围所构建的射频传感网络,手持终端采集的养殖信息,其数据传输丢包率在5%以内,系统运行稳定、可靠、数据能够实时、高效传送到溯源数据中心。
The development of embedded technology and wireless communication technology provide the necessary technical means for dairy cattle breeding. Based on analysis of the current method for dairy information collection and transmission, a new method was proposed which integrating RFID technology with wireless sensor network. The network architecture and communication protocol conversion process were investigated and the method was put into practice to develop the traceability information acquisition and transmission system for dairy cattle. Test results show that based on point to point communication method, the wireless sensor network could work in a range of 35 m with barrier and 75 m with barrier-free to effectively collect dairy information and transmit to the data center. The traceability information system can work real-time, steadily and reliability with package loss rate less than 5%.
