摘要： A multiplex transmission system, in which a node as a transmission node transmits data frame by frame to a transmission path, and a plurality of other nodes, as reception nodes, returns a reception acknowledgment signal to the transmission path upon proper reception of the frame of data. Each of the reception nodes which properly received the frame returns the reception acknowledgment signal specific thereto to that division of a reception acknowledgment signal area in the frame which corresponds to this node. Each node discriminates the success/failure of signal transmission, by comparing the information registered beforehand in its reception acknowledgment signal table with the information in the reception acknowledgment signal area. When the information of the reception acknowledgment signal table does not coincide with that of the reception acknowledgment signal area, the transmission node re-transmits the frame and the reception acknowledgment signal tables of all the nodes are updated. The system can not only effect the addition and deletion of multiplex nodes easily without requiring the change of scale of the circuit of the system, but also discriminate trouble for each of the multiplex nodes.

摘要： A multiplex transmission system, in which a plurality of nodes are coupled together through a transmission path, and a node as a transmission node transmits a frame of data including a data area containing transmission data, to other nodes as reception nodes through the transmission path. The frame of data includes a data valid/invalid area having the same bit length as the data area and indicating, bit by bit, the validness/invalidness of the data carried by the corresponding bits in the data area. The system need not be modified depending on the model and grade of vehicles, and can be used widely and applied to various options by the use of a signal allocation system common to different models and grades of vehicles. Those bits in the data area which correspond to the bits in the data valid/invalid area indicative of data invalidness may have values thereof set to a fixed value, so that the reception node judges the transmission node to be defective when a bit of the data valid/invalid area of the received frame and the corresponding bit of the data area of the received frame make a combination of specific values.

摘要： A multiple transmission system for use in a vehicle, in which a second node having a control function sends an command to first nodes of an ordinary type when an transmission error higher than a certain level takes place or at certain time intervals to effect system refreshment which resides in the following operation. Each of the first nodes, which has received the command, sends its status information (e.g., the status of an input device element such as a sensor or switch) to the other nodes. The other nodes which receive this information initialize their status (e.g., the status of an output device element such as an actuator or a motor) according to the received status information.

摘要： 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.

摘要： 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.

摘要： 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. When the data transmission was carried out properly, the subnode returns a signal ACK3, and when the data transmission failed, the data frame is retransmitted, whereby the subnode need not have an ACK management function.
