Design and Implementation of Train Ethernet Card Based on Deterministic Scheduling
Ethernet card in the Ethernet-based train network control system generally uses software to implement the communication function.This approach is non-ideal because of poor real-time performance and high uncertainty when sending and receiving train real-time data protocol(TRDP)messages.This paper analyzes the source of this defect from the perspective of message processing,and proposes a real-time Ethernet card design for trains based on deterministic scheduling,then introduces its hardware and software design scheme.A test environment was built for comparative testing,which verified the real-time and deterministic improvement of the real-time Ethernet card for TRDP communication.
