The invention provides a protocol converter for a FlexRay bus and a PC104 bus. The converter comprises base hardware and support software, wherein the base hardware comprises a power supply adapting module and a protocol conversion module, and the support software is a finite state machine implemented based on state query and response mechanism. The protocol converter can efficiently and reliably realize bidirectional communication between nodes of the FlexRay bus and the PC104 bus in real time, meanwhile, positions, identifies, analyzes, tracks and detects the bus communication fault, solves the problems of signal interfaces and data exchange between the FlexRay bus and the PC104 bus, and has the advantages of low network time delay, reasonable dynamic distribution of data frames, accurate and quick fault positioning and convenience for quick and effective integration of a multi-bus control system.
Description
technical field [0001] The invention belongs to the technical field of field bus communication control, in particular to a protocol converter for FlexRay bus and PC104 bus. The invention can be used in automobile electronic control systems and industrial bus control systems. Background technique [0002] In automotive electronic control systems and industrial bus control systems, multiple bus technologies are often used in the same control system. The signal interface and protocol conversion between buses directly affect the rapid and effective integration of the entire control system. As a new high-speed bus with transmission determinism and fault tolerance mechanism, FlexRay bus also needs to solve the interface problem with PC104, USB, CAN and other buses widely used at present. Contents of the invention [0003] In order to solve the problem of signal interface and protocol conversion between the FlexRay bus and the PC104 bus, the invention provides a protocol conve...
