Patent number: 6414941Abstract: A communication frame has a counter value which is updated each time the communication frame passes through a node, and a source address. Therefore, upon receiving the communication frame, the node references a source address to check to see if the communication frame was generated by the node, that is, if the communication frame is a returned frame. In addition, even when the node finds that the received communication frame is not the communication frame generated by this node, the node checks counter value information in the communication frame to check to see if the communication frame has already circulated around the network, that is, if the communication frame is abnormal. Furthermore, because the counter value information is provided in each communication frame, the present invention is compatible with a system where a plurality of communication frames are on a network at the same time.Type: GrantFiled: April 20, 1999Date of Patent: July 2, 2002Assignee: Yazaki CorporationInventor: Katsumi Murakami

Patent number: 6253335Abstract: A network abnormality recovery method and system capable of recovering the normal state of a network communication function as soon as possible even if the network communication function is impaired. When it is determined that a network communication function is impaired because a broken line occurs on a main data transmission line or an abnormal condition occurs in a communication IC, a CPU of a station unit transmits network maintaining information required for maintaining the network communication function to another CPU of a master station unit over a sub data transmission line provided separately from the main data transmission line, thereby recovering the normal state of the network communication function as soon as possible.Type: GrantFiled: April 15, 1998Date of Patent: June 26, 2001Assignee: Yazaki CoporationInventors: Katsutoshi Nakajima, Hiroshi Nishiyama, Katsumi Murakami, Akira Norizuki, Yoshiyuki Furuya
