【摘要】：物联网技术的快速发展与广泛应用使得人们的生活水平不断提高,车联网作为物联网的一个重要分支受到不断的关注,当今物流行业发展迅速,但物流车辆监管系统支持的车载终端类型单一,因此开发支持多种终端协议的物流车辆公共平台具有重要的研究意义。本文依托湖北省科技支撑计划项目《基于车联网的物流车辆协同监管关键技术及应用示范》(2014BAA146)对物流车辆公共平台进行研究。主要研究内容如下:1、业务分离的系统平台架构设计。结合物流车辆特性,对现有系统架构方案进行分析,确定系统架构的五大模块:负责GPS车载终端对接的网关服务器,负责平台对接的通讯服务器,负责业务处理的业务服务器,负责数据存储的数据库服务器,负责用户交互的Web服务器。2、兼容部标和非部标协议的模块间通信数据格式的制定。不同车载终端上传的GPS数据格式不同,建立模块间统一的通信数据格式,便于系统模块间数据通信。通过对数据格式的对比,最终选取JSON为通信数据格式,对数据的功能进行分类和整合,确定通信数据中的具体功能格式。3、数据库分库分表并结合MVC三层架构对系统进行设计。首先,通过对MSMQ、ZMQ等五种消息队列框架的对比,选取ZMQ为模块间通信框架;其次,通过Sharding技术把数据库垂直切分为基本信息、GPS定位、百度纠偏三个数据库,并对GPS定位数据库按月进行水平分库,对百度纠偏数据库按地区分表;第三,对业务中心模块的业务划分为实时数据传输、报警处理、油耗分析、调度处理等模块,并完成此模块的开发与设计;最后,对Web服务器选用MVC三层架构模式进行开发,对系统进行整体测试,完成对系统的部署和发布。本文设计的兼容多种类型车载终端的物流车辆公共平台具有较高的实用性。通过此公共平台对物流车辆实行统一化管理,减少交通事故的发生,提升物流车辆的运作效率。
[Abstract]:With the rapid development and wide application of Internet of things technology, the standard of living of people has been continuously improved. As an important branch of the Internet of things, car networking has been paid more and more attention, and the logistics industry is developing rapidly. However, the logistics vehicle supervision system supports a single type of vehicle terminal, so it is of great significance to develop a public platform for logistics vehicles that supports a variety of terminal protocols. This paper studies the public platform of logistics vehicles based on Hubei Provincial Science and Technology support Project < key Technology and Application demonstration of Logistics vehicle Collaborative Supervision based on vehicle networking "(2014BAA146). The main research contents are as follows: 1, system platform architecture design of service separation. Combined with the characteristics of logistics vehicles, the paper analyzes the existing system architecture and determines the five modules of the system architecture: the gateway server responsible for docking GPS vehicle terminals, the communication server responsible for platform docking, and the service server responsible for business processing. The database server is responsible for data storage, the Web server. 2 is responsible for user interaction, and the data format for communication between modules compatible with the standard and non-standard protocols is formulated. Different vehicle terminals upload GPS data in different formats. A unified communication data format between modules is established to facilitate data communication between system modules. Through the comparison of data format, finally select JSON as the communication data format, classify and integrate the function of the data, determine the specific function format of the communication data .3. the database is divided into tables and the system is designed with MVC three-tier architecture. First of all, through the comparison of five message queue frameworks, such as MSMQ and ZMQ, ZMQ is selected as the communication framework between modules. Secondly, the vertical segmentation of the database is divided into basic information and GPS positioning through Sharding technology, and Baidu corrects three databases. At the same time, the GPS positioning database is divided into monthly horizontal database, and Baidu correction database is divided into regional tables. Third, the business of the business center module is divided into real-time data transmission, alarm processing, fuel consumption analysis, dispatch processing and other modules. The development and design of this module is completed. Finally, the Web server is developed with MVC three-tier architecture pattern, and the system is tested as a whole to complete the deployment and release of the system. The public logistics vehicle platform designed in this paper, which is compatible with many types of vehicle terminals, has high practicability. Through this common platform, logistics vehicles are managed in a unified way to reduce traffic accidents and improve the operational efficiency of logistics vehicles.
