Study on service-oriented framework of information integration of safety and security for high-speed railway

In order to improve information transparency, the technology of safety and security for high-speed railway based on integrated information needs to be researched and developed. After the deep analysis of the characteristics of safety and security for high-speed railway and its information processing, a service-oriented framework of information integration of safety and security for high-speed railway has been constructed, consisting of four layers, basic platform layer, data organization layer, key service layer and application layer. The key technology and interfaces of the framework has been studied to realize a prototype system. The framework breaks the hard situation of various information systems at present, which are always independent and have difficult data sharing. The framework makes a system more dynamic and expansible and is easy to establish different service modes for users with different information requirement.
