<p>PROBLEM TO BE SOLVED: To classify the reliability of reception data when the reliability of the reception data is difficult to guarantee due to a fault in a packet communication system.SOLUTION: A packet communication system, including a transmitter and a receiver, in which the transmitter transmits a communication packet and the receiver demodulates reception data from the received communication packet, includes a fault communication line to notify the receiver of the device fault information of a transmitter. The transmitter includes transmission means of fault information occurring in the device, through the fault communication line. The receiver includes: a fault information storage unit for storing the fault information of the transmitter, including a fault occurrence time, received through the fault communication line; a reception data storage unit for storing reception data together with transmission time information or reception time information; and a reliability evaluation unit for granting, by referring to the fault information, a reliability level according to the fault information, for each predetermined time zone of reception data.</p> |
