Patent number: 5499247Abstract: A multiplex transmission system includes a plurality of multiplex nodes interconnected by a common multiplex transmission line. Data frames are transmitted among the multiplex nodes through the multiplex transmission line. A data frame transmitted from a sending multiplex node includes a data area which is divided into subdivided areas in accordance with data transmitted therefrom and data transmitted from receiving multiplex nodes which send data in response to a send request, in accordance with the number of data pieces or the number of bits, and the receiving nodes send data to respective subdivided areas in a predetermined order, to thereby carry out a data transmission. Accordingly, the sending multiplex node can simultaneously collect data from the receiving multiplex nodes which are functionally subordinate. When any of the receiving multiplex nodes fails to return an ACK signal, the sending multiplex node retransmits the data frame.Type: GrantFiled: January 18, 1994Date of Patent: March 12, 1996Assignees: The Furukawa Electric Corp., Mazda Motor Corp.Inventors: Yutaka Matsuda, Hiroo Moriue, Kyosuke Hashimoto, Mitsuru Akimoto, Seiji Hirano, Osamu Michihira, Koji Terayama, Hiroaki Sakamoto, Koji Umegaki

Patent number: 5398240Abstract: In a multiplex transmission apparatus and a multiplex transmission method when a control unit reads reception data while a status flag is set, it determines that the reception data is obtained before data in a transmission buffer is transmitted. When the control unit reads the reception data while the status flag is reset, it determines that the read data is response data to transmission data. Thus, the control unit precisely recognizes the time series of data on communication control.Type: GrantFiled: December 24, 1992Date of Patent: March 14, 1995Assignee: Mazda Motor CorporationInventors: Takashi Nakashima, Yoshikazu Nobutoki, Osamu Michihira, Toshimichi Tokunaga

Patent number: 5357525Abstract: A multiplex transmission system of this invention includes a plurality of multiplex nodes interconnected by a common multiplex transmission line. A frame of data is transmitted among the multiplex nodes through the multiplex transmission line. When a data frame transmitted from an air conditioner switch multiplex node (subnode) is received, an air conditioner unit multiplex node (main node), which is predetermined as a destination node, detects the contents of each data from an ID-a of the received data, performs a calculation on SOM to DATA 4 received, generates collation data (CRC) in accordance with the result of the calculation and transmits same. The subnode generates collation data (CRC), which is an error check code, through a calculation on the transmitted SOM to DATA 4, and compares the thus-generated CRC with the CRC received from the main node, to determine whether or not the data transmission was properly carried out.Type: GrantFiled: March 31, 1992Date of Patent: October 18, 1994Assignees: The Furukawa Electric Co., Ltd., Mazda Motor Corp.Inventors: Hiroo Moriue, Yutaka Matsuda, Kyosuke Hashimoto, Kiyoshi Inoue, Seiji Hirano, Osamu Michihira, Yoshikazu Nobutoki, Hiroaki Sakamoto
