Research And Implementation On An Operation Management System For AFC Equipments Of Rail Transit

As the urbanization process in china is speeding up, a rapid development of rail transit construction for the cities of large and middle size has been presented. The efficient operation and management of rail transit AFC equipments is an important guarantee for the normalization operation of entire city's rail transit. AFC system has the features that there is variety types, a large quantity, a distribution wide, status diversifications in operation and etc. Its special terminal equipments, beside the comprehensive information management capabilities such as the centralized information management, distributed monitoring in real time and etc. A distributed monitoring in real time must be implemented for the operation status of AFC system's equipments, the operation data generated by the equipments should be transmitted to the station computers in time, and then be transmitted to the line central computer system through the station computers. It brings a great deal of technical difficulties for the operation management work of the entire system's equipments.The author in this thesis proposes that an operation management system for AFC equipments of rail transit can be designed and implemented by adopting the system development process based on components and framework, an actual project of Shenzhen Urban Rail Transit Line 4 (Phase 2) AFC system is combined as the basis for application of the key techniques of components, frameworks and etc, and an analysis method has also been discussed for hot spots and stable spots of the framework.The author's main innovation work is summarized as the followings:1) Through analysis and collation of relevant literatures inside and outside of China, and based on the specific projects, the business operations of rail transit AFC equipments has been analyzed and modeled in details; 2) The key techniques of the equipment operation management system have been studied and implemented, i.e., the techniques of software reuse and database synchronization are designed and applied;3) The system development process adopting components-based and framework-based has been proposed, the analysis, design and implementation process for hot spots and stable spots of the framework have been introduced in emphasis, and are illustrated by examples;4) The integration, deployment scheme and its application examples of the entire system have been presented and described.The partial results mentioned as the above studied by the author in this thesis have been applied to the development process of the equipment operation management sub-system for Shenzhen Urban Rail Transit Line 4 (Phase 2) AFC System, and the testings and validatings for its prototype system have been passed by the project group too.
