Abstract
PURPOSE:To improve reliability of data transmission by using a simple program, by performing majority operation on the receiving side even when errors of several bits are generated and automatically correcting the generated code errors. CONSTITUTION:A transmission side device 10 and a reception side device 20 of data transmssion are connected by a communication circuit 30. Data consists of a frame of tens bits are stored in a data memory 14 of the device 10, and a transmission carrier circuit 11 is controlled by a processor 12 in accordance with the read program from a program memory 13. Frames are continuously, 2n+1 time (n: positive integer previously set), transmitted on the circuit 30 from this circuit 11, and data of series bits on the circuit 30 are received by a receiving carrier circuit 21 of the receiver. Data are classified by each time of 2n+1 time by a processor 22 and are stored in a data buffer memory 24. Logical majority operation at every 2+n is performed by the processor 22 in accordance with the program of the program memory 23 and code error is automatically corrected.
