Patent ID: 7698039

Claim:
A mobile communication system which is provided in a mobile body and communicates via a communication network, said system comprising: a plurality of nodes; a path control device which receives data from the nodes respectively, selects a path for data transfer on the communication network, and outputs the data; first optical fibers which connect each of the nodes and the path control device to transfer the data; and second optical fibers which connect each of the nodes and the path control device, in parallel with the first optical fibers, wherein the path control device communicates with the node via the second optical fiber when a failure occurs in the first optical fiber, wherein the node is any one of a sensor, and a control unit which controls an equipment provided in the mobile body, and at least one node is a total-control device which performs a signal processing on information transmitted from at least one of the sensor and the control unit, and issues an instruction to the control unit, said mobile communication system further comprising: a bit error correcting section configured to correct a bit error, being provided in the path control device and the nodes respectively.
