The invention discloses a data stream splitting and transmission method and system based on semantics and time delay sensitivity, and relates to the technical field of wireless communication and power system automation. A sending end carries out service semantic analysis on a to-be-sent service data stream, determines a minimum semantic integrity condition based on time delay sensitivities corresponding to different service semantics, and splits an original data stream into a plurality of micro data units which can be independently scheduled, independently transmitted and independently reconstructed. The micro data unit is generated without depending on a fixed data frame or a preset packaging length, and directly participates in resource allocation and transmission processes as a minimum scheduling object in a wireless communication system. And the receiving end dynamically reconstructs and processes the received data according to the semantics and dependency information carried by the micro data unit without waiting for the arrival of a complete data frame or complete service data. By means of the mode, the structural time delay in the wireless communication process can be effectively compressed, and the real-time communication performance of key services in a transformer substation is improved.
