The embodiment of the invention relates to a processing method for transmitting and receiving data signals by a master-slave network based on a power line. The method comprises the following steps: constructing the master-slave network; when the host sends a high/low level data signal to the slave, the host controls the output level state of the host to be in an opposite low/high level state, so that the slave is activated to finish corresponding high/low level data signal receiving processing locally; and when the slave sends a high/low level data signal to the host, on the premise of confirming that the output level state of the host is a high level state, the slave completes corresponding setting locally according to the high/low level characteristics of the data signal, and the host receives and processes the data signal according to the sampling voltage of the current sampling resistor RS in the host. According to the invention, the realization difficulty and the realization cost of the master/slave can
