【摘要】：随着互联网技术日新月异地发展与完善,物流行业信息化建设也有了巨大的进步。然而,数据源异构问题、物流信息系统的兼容性问题一直制约着物流信息化前进的步伐。这些数据源设备往往在功能设计、接口参数和通信协议等方面都存在着巨大的差异。针对各物流信息系统数据源设备的差异问题,开发人员必须对不同设备进行单独开发,这往往会增加程序设计的难度和复杂度,代码重复现象严重。然而,由厂商和用户统一弥补相关设备的差异是不现实也是不客观的。目前,各物流企业急切地需要开发出一种中间适配器来连接下层的物理设备和上层的物流信息系统,以解决数据异构的问题。本文基于面向对象模型和中间件技术,论述了物流信息系统异构数据采集模块是一种数据服务中间件,使其能够通过配置来进行对采集设备的适配应用。首先,本文研究了物流信息系统平台的开发技术；然后,为了解决物流信息系统数据源中存在的异构数据采集问题,研究了数据集成技术和数据采集技术；其次,针对物流信息系统异构数据的差异问题,对中间件模型做出了研究,设计并实现了物流信息系统异构数据服务器层的核心部分。最后,详细设计了异构数据服务器模块和其模型的工作流程。本文的最后主要介绍了自适应异构数据采集模型在应急成品粮物流信息系统项目中的适配应用。按照本文设计的模型,开发人员可以不再对物流信息系统各异构数据源进行单独开发,只需通过对异构数据服务器模型进行系统配置以及遵守相应的协议规范,就可以采集到各车载终异构的数据并进行正确地解析,这既避免了软件重复开发,也对物流信息系统的发展起到了重要的意义。
[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.
