| Title | Design and Implementation of Principle Prototype of Radio Block Center Based on MCU |
| Abstract | Chinese high-speed railway is developing rapidly, which demands urgently of equipping advanced, safe and reliable railway signaling system for train operation safety. The Track circuit Based Train Control system (TBTC) can’t satisfy the safety requirement as the train speed increased, while the Communication Based Train Control system (CBTC) can. Radio Block Center (RBC) is the kernel subsystem of the ground system in high-speed railway signaling system. The information of train operation state and train control is transferred between RBC system and Centralized Traffic Control system (CTC); the information of train operation state and route state is transferred between RBC system and Computer Interlocking System(CIS); the information of train operation state, movement authorities and train interval control is transferred between RBC system and Train On-board system; the handover of train control is realized between RBC system and neighborhood RBC system. RBC system makes key effect of actualizing the function of “operation commanding, safety protection” in the high-speed railway signaling system.At present, the research on the RBC system abroad is mature, while the domestic counterpart is still at the start stage. The functional requirements and implementation scheme were presented based on the functional decomposition of the signaling system introduced by high-speed railway project. And a RBC principle prototype based on MCU and CAN bus was developed, the running environment of RBC principle prototype for simulation was constructed. The software & hardware debugging and functional experiment were completed.Research works in this paper are focused on the followings:Firstly, the working principles of RBC system in the signaling system of different architecture were studied, the scheme of functional decomposition of signaling system was described, and the functional requirements and implementation scheme of RBC system were presented. The interior and exterior architecture of RBC system were analyzed, and the architecture of RBC principle prototype was designed.Secondly, the principle prototype hardware architecture was designed, and the principle prototype consisting of kernel 2OO2M2 processing unit, voting unit, switch unit and communication unit based on Mega128, CAN bus was developed. The safety and reliability of the principle prototype were analyzed. Thirdly, the principle prototype software architecture was designed. The software modules for train registration, start-up, operation control, switch between RBC system and neighborhood RBC system or different line levels and communication were complied according to the RBC system’s technical specification. And the operation control module was composed of train receiving, departure, passing and block running etc.Finally, the external running environment for simulation was constructed, and the software testing was completed, then the hardware debugging was realized. At last the functional experiment of the principle prototype with CTC, CIS and Train On-board system was realized. |
