【摘要】：得益于现代通信与计算机技术的快速发展,物流日趋信息化和自动化,物流信息系统应运而生,促使物流运作更加高效和稳定可靠。在计算机通信领域里,无线传感器网络一直是一个研究热点,其在物流信息系统上亦有良好的应用前景,例如监测物流运输过程和仓储环境等。使用无线传感器网络进行监测需要进行数据采集和查询。本文首先针对无线传感器网络查询中的数据处理问题,提出了基于均值预期的差值传输算法,该算法在特定的数据模型下计算均值作为预期值,进而通过传输采集值和预期值两者差值的数据达到减少节点数据发送的数据量,降低能耗,延长网络生命周期,保证物流信息系统稳定运行的目的。然后,本文在TinyOS无线传感器网络操作系统基础上,设计并开发了基于无线传感器网络的物流仓储环境监测系统,作为无线传感器网络在物流信息系统中的一个Web应用实例,同时介绍了该系统的搭建、开发和配置过程。
[Abstract]:With the rapid development of modern communication and computer technology, logistics becomes more information and automation, and logistics information system emerges as the times require, which makes logistics operation more efficient and stable and reliable. In the field of computer communication, wireless sensor network (WSN) has been a research hotspot, and it has a good application prospect in logistics information system, such as monitoring logistics transportation process and storage environment. Monitoring using wireless sensor networks requires data acquisition and query. Aiming at the problem of data processing in wireless sensor network query, a difference transmission algorithm based on mean expectation is proposed in this paper, which calculates the mean value as expected value under a specific data model. By transmitting the data of the difference between the collection value and the expected value, the purpose of reducing the amount of data sent by the node data, reducing the energy consumption, prolonging the network life cycle and ensuring the stable operation of the logistics information system can be achieved. Then, based on the TinyOS wireless sensor network operating system, this paper designs and develops the monitoring system of the logistics storage environment based on the wireless sensor network, as a Web application example of the wireless sensor network in the logistics information system. At the same time, the process of building, developing and configuring the system is introduced.
