Abstract
A multipath transmission system of this invention includes a plurality of multiplex nodes connected in parallel to three common signal transmission lines. The multiplex node includes a transmission control circuit which is allotted to a corresponding one of 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. It includes a voltage detection circuit for detecting a voltage generated in at least one of the transmission lines, a reception control circuit for specifying the transmission state of the signal transmission line according to a voltage detected by the voltage detection circuit, a communication control device for communicating with the multiplex nodes to detect fault, and a voltage setting circuit for changing a voltage of the signal transmission line when fault is detected by the communication control device.
