【摘要】：随着传感器网络的发展以及肉品中冷链物流技术需求的迫切性，将WSN应用到肉品冷链物流中已成为一种必然的趋势。本文对WSN进行了深入研究，将以ZigBee技术为基础的WSN应用到肉品冷链物流中。主要实现了肉品冷链物流运输过程中冷藏车厢内对冷鲜肉和各类低温肉制品温度的实时采集和监控，此外，针对冷鲜肉排酸车间（冷库）等大空间场合中的温度监控，本文对WSN空间定位技术进行了研究。本文主要分析了肉品冷链物流和WSN的实际背景及具体意义。对冷链物流中WSN系统中的关键技术进行了综述，分析了ZigBee技术的特点、体系结构以及协议标准等，研究了GSM短信技术的现状以及常用的AT指令等。本文设计的肉品冷链物流中WSN体系结构包括终端局域网络、骨干传输网络及业务管理网络。终端局域网络平台的构建用到的主要元器件有CC2430芯片和DS18B20传感器等，，骨干传输网络平台构建时选用的是GSM短信模块。同时，对这两个平台进行了测试。在硬件平台构建的基础之上设计和开发的肉品冷链物流中WSN系统软件包括ZigBee网络中软件的设计开发、GSM短信通信软件的设计开发以及上位机监控软件的设计开发。ZigBee网络实现了冷链物流过程中冷藏车厢内温度数据的实时采集和传输，GSM短信通信主要实现了两个GSM短信模块之间的数据传输和接收，上位机监控软件主要实现了上位机工作人员对温度数据的实时监控，以便在温度数据发生异常时及时采取措施。为了保障肉品在排酸车间（冷库）等大空间场合中的质量，本文研究了WSN定位技术并且设计了一种WSN三维空间定位方法，这种方法充分利用了目前较为成熟的WSN平面定位技术并且结合了本文设计的移动锚节点来实现。
[Abstract]:With the development of sensor network and the urgency of the demand for the cold chain logistics in meat products, it has become an inevitable trend to apply WSN to the cold chain logistics of meat products.
This paper makes a deep research on the WSN based on ZigBee WSN is applied to the meat cold chain logistics. Mainly realizes the inside of the cold meat and all kinds of meat products of low temperature real-time temperature acquisition and monitoring, chilled meat cold chain logistics and transport process in the cold fresh meat acid workshop (cold) temperature in the monitoring of large space, this paper studied the WSN space positioning technology.
This paper mainly analyzes the practical background and the specific meaning of meat cold chain logistics and WSN. The key technology of WSN system in cold chain logistics are discussed in the article, analyzes the characteristics of ZigBee technology, the system structure and protocol standards, studies the present situation of GSM technology and the commonly used AT commands.
Meat cold chain logistics in the design of the WSN architecture includes terminal network, backbone network and business network management terminal. Local area network platform mainly used components with CC2430 chip and DS18B20 sensor, backbone transmission network platform construction is the selection of the GSM SMS module. At the same time, on the two platform for the test.
The design and development of WSN system software including software ZigBee in the network of meat cold chain logistics design and development based on the hardware platform in the design and development of.ZigBee network GSM SMS communication software design and PC monitoring software to realize the real-time data acquisition and transmission of temperature refrigerated compartment of the cold chain logistics process, GSM SMS communication mainly realizes the data transmission between two GSM SMS module and receiving PC monitoring software to achieve the real-time monitoring of temperature data of the staff of PC, to take timely measures to occur in abnormal temperature data.
In order to ensure meat in acid workshop (cold) quality in big space, this paper studies the WSN positioning technology and the design of a WSN three-dimensional space positioning method, this method makes full use of the WSN plane positioning technology is more mature and the combination of the mobile anchor node is designed to achieve.
