【摘要】：得益于現(xiàn)代通信與計算機技術(shù)的快速發(fā)展,物流日趨信息化和自動化,物流信息系統(tǒng)應運而生,促使物流運作更加高效和穩(wěn)定可靠。在計算機通信領域里,無線傳感器網(wǎng)絡一直是一個研究熱點,其在物流信息系統(tǒng)上亦有良好的應用前景,例如監(jiān)測物流運輸過程和倉儲環(huán)境等。使用無線傳感器網(wǎng)絡進行監(jiān)測需要進行數(shù)據(jù)采集和查詢。本文首先針對無線傳感器網(wǎng)絡查詢中的數(shù)據(jù)處理問題,提出了基于均值預期的差值傳輸算法,該算法在特定的數(shù)據(jù)模型下計算均值作為預期值,進而通過傳輸采集值和預期值兩者差值的數(shù)據(jù)達到減少節(jié)點數(shù)據(jù)發(fā)送的數(shù)據(jù)量,降低能耗,延長網(wǎng)絡生命周期,保證物流信息系統(tǒng)穩(wěn)定運行的目的。然后,本文在TinyOS無線傳感器網(wǎng)絡操作系統(tǒng)基礎上,設計并開發(fā)了基于無線傳感器網(wǎng)絡的物流倉儲環(huán)境監(jiān)測系統(tǒng),作為無線傳感器網(wǎng)絡在物流信息系統(tǒng)中的一個Web應用實例,同時介紹了該系統(tǒng)的搭建、開發(fā)和配置過程。
[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.
