The application relates to the technical field of wireless communication and data transmission, and discloses a main-backup link digital transmission control method and system of an intelligent fusion terminal, wherein the method comprises the following steps: acquiring multi-dimensional observation parameters of a main link and a backup link and constructing a normalized vector; forming a main-backup link fusion score; constructing short window and long window exponential average values; calculating a score residual, a degradation energy quantization value and a cumulative degradation amount; generating a pre-switching control parameter; performing shunt transmission of a service packet; and completing session context migration and old link release.
