【摘要】：隨著互聯(lián)網技術日新月異地發(fā)展與完善,物流行業(yè)信息化建設也有了巨大的進步。然而,數(shù)據(jù)源異構問題、物流信息系統(tǒng)的兼容性問題一直制約著物流信息化前進的步伐。這些數(shù)據(jù)源設備往往在功能設計、接口參數(shù)和通信協(xié)議等方面都存在著巨大的差異。針對各物流信息系統(tǒng)數(shù)據(jù)源設備的差異問題,開發(fā)人員必須對不同設備進行單獨開發(fā),這往往會增加程序設計的難度和復雜度,代碼重復現(xiàn)象嚴重。然而,由廠商和用戶統(tǒng)一彌補相關設備的差異是不現(xiàn)實也是不客觀的。目前,各物流企業(yè)急切地需要開發(fā)出一種中間適配器來連接下層的物理設備和上層的物流信息系統(tǒng),以解決數(shù)據(jù)異構的問題。 本文基于面向對象模型和中間件技術,論述了物流信息系統(tǒng)異構數(shù)據(jù)采集模塊是一種數(shù)據(jù)服務中間件,使其能夠通過配置來進行對采集設備的適配應用。首先,本文研究了物流信息系統(tǒng)平臺的開發(fā)技術；然后,為了解決物流信息系統(tǒng)數(shù)據(jù)源中存在的異構數(shù)據(jù)采集問題,研究了數(shù)據(jù)集成技術和數(shù)據(jù)采集技術；其次,針對物流信息系統(tǒng)異構數(shù)據(jù)的差異問題,對中間件模型做出了研究,設計并實現(xiàn)了物流信息系統(tǒng)異構數(shù)據(jù)服務器層的核心部分。最后,詳細設計了異構數(shù)據(jù)服務器模塊和其模型的工作流程。 本文的最后主要介紹了自適應異構數(shù)據(jù)采集模型在應急成品糧物流信息系統(tǒng)項目中的適配應用。按照本文設計的模型,開發(fā)人員可以不再對物流信息系統(tǒng)各異構數(shù)據(jù)源進行單獨開發(fā),只需通過對異構數(shù)據(jù)服務器模型進行系統(tǒng)配置以及遵守相應的協(xié)議規(guī)范,就可以采集到各車載終異構的數(shù)據(jù)并進行正確地解析,這既避免了軟件重復開發(fā),也對物流信息系統(tǒng)的發(fā)展起到了重要的意義。
[Abstract]:With the rapid development and improvement of Internet technology, the information construction of logistics industry has made great progress. However, the problem of heterogeneous data sources and compatibility of logistics information systems has been restricting the pace of logistics information. These data source devices often differ greatly in function design, interface parameters and communication protocols. In order to solve the problem of the difference of data source equipment in each logistics information system, developers must develop different devices separately, which often increases the difficulty and complexity of program design, and the phenomenon of code repetition is serious. However, it is not realistic and objective for manufacturers and users to make up for the difference of related equipment. At present, logistics enterprises urgently need to develop an intermediate adapter to connect the physical equipment of the lower layer and the logistics information system of the upper layer, in order to solve the problem of data heterogeneity. Based on the object-oriented model and middleware technology, this paper discusses that the heterogeneous data acquisition module of logistics information system is a kind of data service middleware, which can be configured to adapt to the acquisition equipment. First, this paper studies the development technology of logistics information system platform; then, in order to solve the problem of heterogeneous data acquisition in logistics information system data source, data integration technology and data acquisition technology are studied. Aiming at the difference of heterogeneous data in logistics information system, the middleware model is studied, and the core part of heterogeneous data server layer of logistics information system is designed and implemented. Finally, the heterogeneous data server module and the workflow of its model are designed in detail. At the end of this paper, the adaptive heterogeneous data acquisition model in the emergency grain logistics information system project is introduced. According to the model designed in this paper, developers can no longer develop each heterogeneous data source of logistics information system separately, but only by configuring the heterogeneous data server model and complying with the corresponding protocol specification. The data can be collected and analyzed correctly, which not only avoids the repeated development of software, but also plays an important role in the development of logistics information system.
