【摘要】:物聯(lián)網(wǎng)技術(shù)的快速發(fā)展與廣泛應(yīng)用使得人們的生活水平不斷提高,車聯(lián)網(wǎng)作為物聯(lián)網(wǎng)的一個(gè)重要分支受到不斷的關(guān)注,當(dāng)今物流行業(yè)發(fā)展迅速,但物流車輛監(jiān)管系統(tǒng)支持的車載終端類型單一,因此開發(fā)支持多種終端協(xié)議的物流車輛公共平臺(tái)具有重要的研究意義。本文依托湖北省科技支撐計(jì)劃項(xiàng)目《基于車聯(lián)網(wǎng)的物流車輛協(xié)同監(jiān)管關(guān)鍵技術(shù)及應(yīng)用示范》(2014BAA146)對(duì)物流車輛公共平臺(tái)進(jìn)行研究。主要研究?jī)?nèi)容如下:1、業(yè)務(wù)分離的系統(tǒng)平臺(tái)架構(gòu)設(shè)計(jì)。結(jié)合物流車輛特性,對(duì)現(xiàn)有系統(tǒng)架構(gòu)方案進(jìn)行分析,確定系統(tǒng)架構(gòu)的五大模塊:負(fù)責(zé)GPS車載終端對(duì)接的網(wǎng)關(guān)服務(wù)器,負(fù)責(zé)平臺(tái)對(duì)接的通訊服務(wù)器,負(fù)責(zé)業(yè)務(wù)處理的業(yè)務(wù)服務(wù)器,負(fù)責(zé)數(shù)據(jù)存儲(chǔ)的數(shù)據(jù)庫(kù)服務(wù)器,負(fù)責(zé)用戶交互的Web服務(wù)器。2、兼容部標(biāo)和非部標(biāo)協(xié)議的模塊間通信數(shù)據(jù)格式的制定。不同車載終端上傳的GPS數(shù)據(jù)格式不同,建立模塊間統(tǒng)一的通信數(shù)據(jù)格式,便于系統(tǒng)模塊間數(shù)據(jù)通信。通過對(duì)數(shù)據(jù)格式的對(duì)比,最終選取JSON為通信數(shù)據(jù)格式,對(duì)數(shù)據(jù)的功能進(jìn)行分類和整合,確定通信數(shù)據(jù)中的具體功能格式。3、數(shù)據(jù)庫(kù)分庫(kù)分表并結(jié)合MVC三層架構(gòu)對(duì)系統(tǒng)進(jìn)行設(shè)計(jì)。首先,通過對(duì)MSMQ、ZMQ等五種消息隊(duì)列框架的對(duì)比,選取ZMQ為模塊間通信框架;其次,通過Sharding技術(shù)把數(shù)據(jù)庫(kù)垂直切分為基本信息、GPS定位、百度糾偏三個(gè)數(shù)據(jù)庫(kù),并對(duì)GPS定位數(shù)據(jù)庫(kù)按月進(jìn)行水平分庫(kù),對(duì)百度糾偏數(shù)據(jù)庫(kù)按地區(qū)分表;第三,對(duì)業(yè)務(wù)中心模塊的業(yè)務(wù)劃分為實(shí)時(shí)數(shù)據(jù)傳輸、報(bào)警處理、油耗分析、調(diào)度處理等模塊,并完成此模塊的開發(fā)與設(shè)計(jì);最后,對(duì)Web服務(wù)器選用MVC三層架構(gòu)模式進(jìn)行開發(fā),對(duì)系統(tǒng)進(jìn)行整體測(cè)試,完成對(duì)系統(tǒng)的部署和發(fā)布。本文設(shè)計(jì)的兼容多種類型車載終端的物流車輛公共平臺(tái)具有較高的實(shí)用性。通過此公共平臺(tái)對(duì)物流車輛實(shí)行統(tǒng)一化管理,減少交通事故的發(fā)生,提升物流車輛的運(yùn)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.
