Application Of Message Queue Technology In Integrated Vehicle Information Platform System

Nowadays,the transportation resources are strained and the number of car ownership increases year by year.People have higher requirements for driving.With the development of the Internet of Things,with the purpose of effectively regulating the operating status of driving vehicles with different functional requirements and providing comprehensive services,a comprehensive information platform for vehicle networking emerges at the historic moment.The integrated information platform for vehicle networking includes many different application systems and massive real-time data.The data transmission between different system platforms and the massive data storage in the management system have become the core technical problems of the integrated information platform for the car network.The specific performance is as follows:The first is the database performance problem caused by managing massive data;the second is that the network protocols and structural connections owned by different system platforms are different,and what kind of technical means is chosen to complete the data between different application systems Communication transmission.According to the above problems,through the analysis of the corresponding technical means,the following solutions are obtained:(1)For mass data in the management database,the code is modified on the premise of no change in the application program,and the system is optimized for processing and use.ORACLE partition technology to deal with the table of large data amount of the three kinds of technical means,the final use of ORACLE partition technology to effectively solve the problem of massive data management.(2)As for the data communication transmission between different application systems,after analyzing the three solutions of FTP transmission,wireless AP transmission,and message queue transmission,the message queue transmission is selected as the data transmission method,and the ORACLE advanced queue technology is adopted.The data transmission features possessed are analyzed in depth.On this basis,ORACLE advanced queue technology is selected as the data transmission method for the integrated information platform of the car network,and compared with the polling technology in experiments,and finally the system is completed.After the advanced queue was built,data transmission performance tests were performed.At present,the integrated information platform for the Internet of Vehicles has already served eight rental and long-distance freight forwarding agencies in six cities including Chongqing,Hohhot and Jining.Through the use of ORACLE advanced queuing technology,data transmission between multiple application platforms has been realized,and on the basis of using only three general-purpose servers,data transmission speed of 28 bits per 30 seconds has been achieved,and a single data transmission only takes about 1 ms.Since the launch of the system platform,there have been no accidents such as the safety of transportation vehicles during the average driving time,which has ensured the safety of life and property of transportation companies and drivers.
