Apparatus for forwarding message based on dynamic priority and apparatus for priority adjustment and method for processing dynamic priority message

1. the art that the invention defined in the claims The present invention will on the dynamic priority message transmission system based on priority and priority adjustment unit and the dynamic priority message processing method using the same. 2. The invention attempts to solve the technical challenges The invention is based on dynamic priority to allow to send and receive data at any time according to the number of nodes and a transmission medium (a communication bus) communication network environment ensures minimum transmission delay time of a message in, and that each node prioritize consisting of to provide a message transmission device and the priority rankings using the same apparatus and message processing method that purpose. 3. Resolution of the subject matter of the invention, The invention, according to a dynamic priority message transmission system based on ranking, a plurality of nodes in communication network environments with record their priorities, and at least first to record the lowest priority in the priority storage means; If the monitor is a communication bus, the communication bus is idle (idle) state monitoring communication bus means for transmitting the message; If from another node at the same time a message is sent, and the it has detected compared to the priority of the node, if his lower priority without sending the message, the priority is high, by sending a message to resolve the message collision resolving conflicting message means; The reporting an identifier of the message to determine if the message is its own node will handle the message filtering means for performing filtering; And according to a predetermined specific rule, and includes the priority adjustment means for adjusting the priority of the corresponding node. 4. An important use of the invention, The invention yiyongdoem such a communication network system. Dynamic priority, CAN, TTP, TTCAN, FlexRay, communication bus, the node
