    摘要: When a message is transmitted, frame by frame, from any one (10) of a plurality of multiplex nodes to a common multiplex bus (MB) to which the multiplex nodes are connected, each of the multiplex nodes (20 and 30) determines that transmission of a frame therefrom is allowed when it detects a transmission permission signal (b, b') added to the frame after detection of and idle state of the multiplex bus, and starts transmitting a message data frame. This makes it possible to properly implement priority-based control according to the priority levels of the data frames irrespectively of variations in the reference clocks of the multiplex nodes. Further, receiving multiplex nodes perform frame synchronization at the rise of a special code (a) of a start code (SOM) of a message data frame, and then perform re-synchronization at the rise of a special bit pattern (b") which includes a passive bit and a dominant bit. This prevents synchronization from being deviated and bit errors resulting from deviated synchronization, thus leading to higher reliability of multiplex transmission.

    摘要: A multiplex transmission apparatus in accordance with the present invention is interconnected with other multiplex transmission apparatuses via common transmission lines, and it is used for a multiplex transmission system which performs data transmission. The multiplex transmission apparatus comprises voltage converting circuits which detect voltages of the transmission lines, the first comparator which compares the detected voltages, the second comparator which compares one voltage of the detected voltages with a reference voltage, and the third comparator which compares the other detected voltage with a reference voltage. The comparators supply the comparison results to differential circuits, respectively, set the output of the differential circuit linked to a comparator, which is connected to a faulty line, for "L", and determine the logical sum of the outputs of the differential circuits by a logical synthesizing circuit. By applying the determined logical sum to a multiplex transmission control circuit, the apparatus makes it possible to reduce wasteful message transmission and successfully cope with faults in the transmission lines without causing delay in transmission of messages which require quick responses and without increasing the traffic volume of the transmission lines. The multiplex transmission control circuit detects signals on the transmission lines according to the comparison results of the comparators.
