PURPOSE: A vehicle information delivery system retransmits the loss of data generating due to data communications error after the arbitrary time waiting. Simply, error is reduced. CONSTITUTION: An optical receiver(210) is attached to the front side of the vehicles. An optical transmitter(220) is attached to the back side of the vehicles. The data processing unit(230) processes the information signal received from the optical receiver. It changes into digital data. The system controller(250) controls transmitting and receiving between the optical receiver and the optical transmitter. |
