Abstract

The invention provides a double-ring optical network communication method and networking used for industrial control field, and relates to the industrial control technology field. A main station device and N substation devices (N is greater than or equal to 1) can be adopted to form a double-ring optical network networking way, and a main channel link is used as the default communication link for the communication. When the error of the data transmission of the communication link occurs, the standby communication links can be started for the communication, and the main communication link is not used for the communication. When the main communication link is restored, the main communication link can be started for the communication, and the standby communication link is not used for the communication. The communication rate and the communication distance can be effectively improved, and the reliability of the whole system can be improved.
