The invention discloses a protocol conversion method of an Ethernet based on a real-time data bus and a 2M multiplex channel. The method comprises the following steps that the control decision information of an IEC103 protocol transceiver module is sent to an information aggregation and distribution module, the control decision information is orderly transmitted to a protocol conversion module and an HDLC protocol transceiver module and then is transmitted to a stability control execution station, the HDLC protocol transceiver module transmits state information to the protocol conversion module and an HDLC protocol transceiver module orderly, and then the IEC103 protocol transceiver module transmits the information to a dispatching end decision server. In the state information transmission, through employing bus no-real-time transmission, the contradiction between the stability control system large-capacity data transmission and real-time data bus bandwidth limitation is solved. In the control strategy transmission, a data block transmission function is used, and the efficiency of real-time data and bus data transmission and the flexibility of real-time data bus use are improved.
