Abstract

The invention relates to a middleware system applied to a rail traffic signal safety system and belongs to the technical field of rail traffic. The middleware system comprises a configurable management module, a bottom layer interface adaption management module, an application development management module and a safety and reliability management module. The configurable management module is configured with an operation system, a drive, a system internal data structure and software and hardware resources; the application development management module is used for providing united APIs (Application Programming Interfaces) for upper-layer application and meanwhile being in charge of information interaction and system initialization; the safety and reliability management module is used for realizing management on system safety and reliability; and the bottom layer interface adaption management module is used for realizing information interaction with other sub-systems in a rail traffic signal system. The middleware system, which can be adapted to different bottom-layer operation systems and applied to various rail traffic safety sub-systems, undertakes a universality task of accessing bottom-layer operation of various application programs and provides universal service for application systems through the simple and convenient public-safety APIs.

Description

Technical field [0001] The invention relates to the technical field of rail transit, in particular to the technical field of rail transit signal safety, and specifically refers to a middleware system applied to a rail transit signal safety system. Background technique [0002] The train control system (CBTC) based on wireless communication realizes the two-way information transmission between trains and ground, breaking through the limitation of traditional track circuit fixed block, using mobile block technology to greatly improve the operation efficiency of trains and the flexibility of the system, which represents the future trains The development trend of automatic control system. The entire CBTC signal system is composed of automatic train monitoring system (ATS), computer interlocking system (CBI), automatic train protection system (ATP) and automatic train driving system (ATO). Among them, CBI, ATP, and ATO are safety-related in the CBTC system The system needs to run in ...
