On Communication and Management of DRTS

The proposed technical measures are briefly stated. As regards communications, there are two measures: the distributed real-time communication mechanism is rationally divided into five logical levels; the Priority-Polling bus control mode is used. As regards schedule, two measures are adopted: global schedule according to the system working mode and local schedule driven by real-time events; the two types of schedule are well coordinated. As regards management, there are three technical measures adopted; broadcasting time synchronization, half-dynamic communication port mechanism, and coherent distributed data management.
