CBTC接口转换应用层设计与实现

Design and implementation of application layer in interface conversion of CBTC

CBTC系统中,多个子系统之间的信息交互是保证系统正常运行的必要条件。为了使不能直接进行信息交互的子系统之间能够正常通信,在北京地铁运营仿真实验室搭建的CBTC最小系统的基础上,设计和实现了接口转换应用层系统,按照用户需求对CBTC各子系统进行接口协议转换。并对接口转换应用层系统进行测试,结果表明系统在平台中运行正常,能够高效、准确、实时的完成信息交互,同时具有良好的通用性,可扩展性和可维护性。

In a CBTC System, the information exchange between the subsystems was necessary to ensure the normal working conditions. To make subsystems of a CBTC System which could not directly interact with the information could communicate properly, it was designed and implemented the Interface Conversion Application Layer System, according to the user＇s requirement, interface protocol conversion was made for each CBTC subsystem based on CBTC Minimum System building by Beijing Subway operation simulation laboratory. The designed System was tested, and it worked well in the platform, could be efficient, accurate, real-time information exchange, and was with good generality, expansibility and maintainability.
