<p>A multipath transmission system for communicating between devices includes a plurality of multiplex nodes connected in parallel to three common signal transmission lines(A,B,C). The multiplex node includes a transmission control circuit(72) which is allotted to a corresponding one of the devices, receives a multiplex signal from the device in response to a transmission request of another multiplex node and transmits the multiplex signal to the signal transmission line(A,B,C). It includes a voltage detection circuit for detecting a voltage generated in at least one of the transmission lines(A,B,C), a reception control circuit(73) for specifying the transmission state of the signal transmission line according to a voltage detected by the voltage detection circuit(74), a communication control device(71) for communicating with the multiplex nodes(10-70) to detect a fault, and a voltage setting circuit(76) for changing a voltage of the signal transmission line when a fault is detected by the communication control device(71). <IMAGE></p> |
