Embodiment Construction

[0042] The present invention will be further described below through specific implementation and accompanying drawings.

[0043] The present invention stores and manages data related to traffic flow calculation based on cloud computing technology, such as figure 1 As shown, it mainly includes distributed file system, columnar database, relational database cluster, parallel processing architecture, memory database and other modules, and completes the storage, preprocessing, calculation and analysis of static data and massive dynamic data. The system can also choose to deploy clusters in the form of virtual machines, which are easier for cluster management and data backup.

[0044] The system is built based on Hadoop and Oracle. With the help of Hadoop's distributed file system HDFS and parallel processing architecture MapReduce, it can effectively store and efficiently process massive data. By building an Oracle RAC real-time response cluster, you can quickly store and read ma...

Abstract

The invention relates to a TMIS traffic flow determination method and system based on cloud computing. The TMIS traffic flow determination method comprises the steps of (1) constructing a distributed storage resource pool on the basis of a cloud platform, collecting and storing monitoring data related to traffic flow calculation through a TMIS, (2) preprocessing the collected monitoring data through a concurrent processing framework, (3) writing a traffic flow calculation algorithm under the concurrent processing framework, utilizing static data for calculating the result of long-term traffic flow calculation, (4) utilizing the static data and dynamic data under the distributed environment for calculating the result of real-time traffic flow calculation corresponding to each station, and (5) providing a traffic flow calculation inquiry service externally through the cloud platform. The TMIS traffic flow determination system comprises a collecting layer, a storage layer, an engine layer, a service layer and a web service layer. According to the TMIS traffic flow determination method and system based on cloud computing, the cloud platform is utilized for obtaining various data required by traffic flow calculation in the TMIS, the concurrent computation is utilized for rapid data processing, and long-term and real-time traffic flow calculation and determination of railway transportation can be achieved.
