Vehicle Monitring System Data Storage Method And Optimization

Along with social progress, economic level, the number of motor vehicles is greatly improved, and the attendant road congestion, increasing traffic accidents and a series of social problems. Vehicle monitoring system is in this context was born, it means systematically solve the above problems, and thus becoming a modern traffic engineering is an important component.After entering the era of massive data, vehicle monitoring system has also ushered in a new development opportunities. In the article from theory to practical starting point, the basic theory of vehicle monitoring system were studied. The main contents and innovations are as follows:1. Development of vehicle monitoring system at home and abroad were reviewed. From a systematic point of view, discusses the overall structure and data storage method for a vehicle monitoring system. For each module and gateway communication system vehicle monitoring service platform for a detailed functional design, and implementation of these functions;2. On the basis of the above study, the author combines reality system case, vehicle monitoring system for problems when faced with massive data storage, analysis of the shortcomings of relational database applications in vehicle monitoring system, given proposed a cloud storage scheme, which is based on Hadoop distributed storage system vehicle monitoring system. Cloud storage platform for Hadoop and HDFS distributed file system are described.3. set up a Hadoop cluster, configure HBase database, oracle database installed, deployed on the application server system for improved system performance test results show that the system is indeed improved storage performance has been improved.4. Special bottleneck situation Hadoop Distributed File System and Storage System-storage of small files, the performance falling instead of rising problems, propose solutions and improvements to be demonstrated. Final conclusion:Hadoop distributed file storage system can solve the problem of mass data storage vehicle monitoring systems encountered, and, through improved Hadoop distributed file storage system at the store massive amounts of small files also have better performance.
