A single wire serial communication method and single wire serial communication system are disclosed. In every communication, the master device transmits a data packet, and each of the plurality of slave devices sequentially receives the data packet. The slave device forwards the data packet to a next slave device, and before the data packet are forwarded to the next slave device, the slave device modifies device address data in the data packet. The slave device compares the device address data in the received data packet with preset data or the device address data transmitted by the master device in order to find at least one target slave device in the communication. The single wire serial communication method and the single wire serial communication system solves a problem of automatic addressing of single wire serial communication of a plurality of same apparatus without performing address initialization, thereby avoiding all communication on the latter stage from influencing due to the failure of the address initialization.
