The invention discloses a CQF mechanism
train communication network scheduling method based on a
time sensitive network, comprising the following steps: establishing a
train communication
network topology model based on a TSN, defining each performance parameter in the
train communication
network topology model, establishing a traffic scheduling model based on the
train communication network topology model, and scheduling the traffic scheduling model based on the
train communication network topology model. Defining performance parameters in a communication
flow scheduling model, defining related constraints based on a
flow scheduling process, constructing an overall flow of a JFRF
algorithm, and establishing a
flow scheduling model with a scheduling success rate as an optimization target on the basis of scheduling constraint conditions; the method comprises the following steps of: constructing a sequencing equation consisting of flow features and
route features by combining flow, offset and
route through the combination of the flow, the offset and the
route, determining and selecting all flow scheduling priorities according to the sequencing equation, and selecting the maximum priority from all the scheduling priorities for scheduling. According to the invention, the process of traffic scheduling can be more efficiently planned, load balancing with a higher level can be realized, and
scheduling resource allocation can be optimized. The problem that part of time trigger flows cannot be scheduled under the background that the data volume is increased in a blowout mode after train intelligentization can be effectively solved.
