Abstract:

To resolve the question of controlling the in-vehicle MOST（Media Oriented System Transport） device node, design and realize a in-vehicle MOST control node. Comparing to the traditional connection methods, MOST bus has the advantages of anti-interference, low quality, high speed,low cost, and etc. With OS81050 and ATmega128, optical fibers are used, control node send message to MOST device nodes. All device nodes can work synchronously. The control node can monitor the status of device nodes, adjust MOST network when the status of a device node is changed.With the research on the principle of MOST network, it becomes foundation and theory to apply MOST technology to in-vehicle electronic technology, smart homes.

Key words: in-vehicle electronic technology, media oriented system transport bus, control node
