The invention discloses a data bus based data acquisition and forwarding mode. The mode is characterized by involving a data bus and members, wherein the members are connected through the data bus; and the members include a communication medium library, a device library, a specification/interface library and a data processing library. According to the mode, an original real-time library based data acquisition and forwarding framework is subjected to business layering and mode transformation to form a data bus based data acquisition and forwarding framework, so that the members can be mutually connected by a public interface, and the plug-and-play, automatic injection and seamless integration of the members are realized; and a data bus and member combined mode is adopted, so that the difficulty of system maintenance is effectively lowered, the repeated work is reduced, a front acquisition framework solves a load balancing problem to a certain extent through a layered framework and distributed deployment, the module reusability is greatly improved, and the program coupling and the repeated development work of programmers are greatly reduced.
