【摘要】：得益于現(xiàn)代通信與計(jì)算機(jī)技術(shù)的快速發(fā)展,物流日趨信息化和自動(dòng)化,物流信息系統(tǒng)應(yīng)運(yùn)而生,促使物流運(yùn)作更加高效和穩(wěn)定可靠。在計(jì)算機(jī)通信領(lǐng)域里,無(wú)線傳感器網(wǎng)絡(luò)一直是一個(gè)研究熱點(diǎn),其在物流信息系統(tǒng)上亦有良好的應(yīng)用前景,例如監(jiān)測(cè)物流運(yùn)輸過(guò)程和倉(cāng)儲(chǔ)環(huán)境等。使用無(wú)線傳感器網(wǎng)絡(luò)進(jìn)行監(jiān)測(cè)需要進(jìn)行數(shù)據(jù)采集和查詢。本文首先針對(duì)無(wú)線傳感器網(wǎng)絡(luò)查詢中的數(shù)據(jù)處理問(wèn)題,提出了基于均值預(yù)期的差值傳輸算法,該算法在特定的數(shù)據(jù)模型下計(jì)算均值作為預(yù)期值,進(jìn)而通過(guò)傳輸采集值和預(yù)期值兩者差值的數(shù)據(jù)達(dá)到減少節(jié)點(diǎn)數(shù)據(jù)發(fā)送的數(shù)據(jù)量,降低能耗,延長(zhǎng)網(wǎng)絡(luò)生命周期,保證物流信息系統(tǒng)穩(wěn)定運(yùn)行的目的。然后,本文在TinyOS無(wú)線傳感器網(wǎng)絡(luò)操作系統(tǒng)基礎(chǔ)上,設(shè)計(jì)并開發(fā)了基于無(wú)線傳感器網(wǎng)絡(luò)的物流倉(cāng)儲(chǔ)環(huán)境監(jiān)測(cè)系統(tǒng),作為無(wú)線傳感器網(wǎng)絡(luò)在物流信息系統(tǒng)中的一個(gè)Web應(yīng)用實(shí)例,同時(shí)介紹了該系統(tǒng)的搭建、開發(fā)和配置過(guò)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.
