Abstract: A single-level single-line full-duplex bus communication method and system are disclosed. The method includes: transmitting, by a first signal transceiver, data according to a first internal transmitter clock F1, simultaneously monitoring a level change on a bus, and parsing received data; transmitting, by a second signal transceiver, data according to a second internal transmitter clock F2, simultaneously monitoring the level change on the bus, and parsing received data; and communicating between the first and second signal transceivers by means of a single line, wherein the first and second transmitter clocks satisfy a relationship: F1>F2*(length of data unit+2). The system achieves single-level single-line full-duplex communication by using different coding formats and different internal transmitter clocks, whereby the number of signal lines can be reduced, single-level communication can be achieved by using universal digital levels, i.e., 0, 1, and the hardware implementation difficulty can be reduced.
