A Data Communication Method Based on Multi - field Bus

A design of multi - field bus data communication method based on middleware is proposed and its system realization is achieved. The middleware encapsulates the user data into a functional frame, converts the functional frames into target frames corresponding to the bus type parameters according to the bus type parameters and the preset transmission and reception policies, and transmits the target frames through the bus corresponding to the bus type parameters, Scalability and compatibility, compatible with windows and Linux system. Given the middleware hierarchy, chart flow, the test results show that the middleware has successfully implemented the data transmission between the Ethernet bus, CAN bus and RS422 bus.
