Abstract
The invention discloses a GIS double-fiber data transmission and processing method. The method comprises the steps that: a GIS digital interval measurement and control device is connected with the first to the Nth communication modules of an intelligent monitoring device in sequence by a double-path fiber to form a double circuit; the GIS digital interval measurement and control device sends two data frames which are opposite in directions to the double circuit; each communication module of the intelligent monitoring device receives the data frames which are sent to the circuit and changes data of the data frames and then transmits the changed data to the next communication module of the intelligent monitoring device; when an entire frame data packet is completely sent, the communication modules of the intelligent monitoring device compare the data frames in the different directions in the double circuit; and if a comparison result shows an abnormal condition, the path is connected with another path to ensure the normal sending of the data packet. In the invention, if data errors occur due to the failure of one or two paths of fiber in a data transmission process, the double-fiber transmission can be changed into transmission network with two single fibers in time, so the normal data transmission is effectively guaranteed and the GIS equipment control stability is realized.
