PURPOSE:To ensure the reception of the diagnosis data without being affected by the difference of the transmission control sequence and the synchronizing system by constituting the data processor so that all the data transmitted from the communication control unit may be received continuously. CONSTITUTION:The data transmission system contains data processor 1, channel unit 2 and communication control unit 3 and is then connected to the terminal unit via unit 3 and the communication circuit. In the diagnosis data reception process system for the above data transmission system, reception data buffer 12-1 and 12-2 are installed to store the reception data sent from unit 2 to unit 3 continuously and alternately. Furthermore, command control part 16 to command to store the reception data transmitted from unit 2 into buffer 12-1 and 12-2 in sequence is provided, along with the timer device which checks the contents of buffer 12-1 and 12-2 in the prescribed fixed or variable timing. Thus, the command received from part 16 is indicated to be stored in buffer 12-1 ans 12-2 in the chained form. |
