Abstract: | The operation principle and software design of data transmission interface in DTMF signal mode with strong anti-interference are introduced,and 16 DTMF signal are taken as 16 segment codes of message frame,at the same time check code is adopted to detect error and correct error,thus making bit error rate of data transmission almost reduce to zero. |
