The invention relates to the technical field of communication, in particular to a dynamic priority dual-mode communication fault-tolerant switching method and equipment, and aims to solve the problems of communication interruption and
service quality reduction when a main link is degraded in a complex
electromagnetic environment. According to the method, a dynamic priority evaluation model and a dual-mode protocol cooperation mechanism are constructed,
throughput,
bit error rate,
delay jitter, task semantic priority and aging constraint data of a main link and a standby link are collected in real time, a priority weight and a communication mode
decision matrix are generated through combined modeling, an atomization switching instruction is executed according to the priority weight and the communication mode
decision matrix, and a communication mode is switched. And completing
path reconstruction and resource redistribution. The
system further introduces link health prediction, a resource reservation
pool and an
online learning feedback loop, and supports fault pre-judgment, key task
preemption and model
adaptive optimization. According to the method, the limitation of a static threshold is broken through, the task
semantics and channel state joint scheduling is realized, and the communication reliability, the service continuity and the intelligent fault-tolerant capability of a distributed
system in a high-risk scene are remarkably improved.
