Abstract

Temporary Speed Restriction server (TSRS) is a safety related device in China train operation control system of passenger dedicated line. It uses PowerPC (MPC7455) as the processor, uses vxWorks system as the operate system, uses Ethernet as the communication interface. It builds a comparison computing platform using the VME bus of the MPC7455, uses the vxWorks semaphore method as computing system synchronization mechanism, implements double 2-vote-2 platforms.
