if the main station generates channel receiving direction alarm, analyzing alarm generated by the sub-station:
if the sub-station generates a channel receiving direction alarm, the receiving and transmitting links between the main station and the sub-station are abnormal, the alarm of the communication side is analyzed, and if the communication side does not have the alarm, the alarm between the sub-station and other stations is used for positioning, so that the position of the channel fault is obtained;
If the sub-station generates a channel sending direction alarm, a receiving link between the main station and the sub-station is interrupted, a communication side alarm is analyzed, and if the communication side does not generate an alarm, the sub-station and other stations are positioned by the alarm to obtain the position of the channel fault;
if the substation has no channel alarm, if the communication side has the alarm, adopting the substation to generate the step analysis of channel receiving and sending direction alarm; if the communication side has no alarm, positioning is carried out through the alarm between the substation and other stations, and the position of the channel fault is obtained.
6. The safety and stability control system channel fault positioning device based on the full link alarm is characterized by comprising a processor and a storage medium;
the storage medium is used for storing instructions;
The processor being operative according to the instructions to perform the steps of the method of any one of claims 1 to 4.
7. Computer readable storage medium, on which a computer program is stored, characterized in that the program, when being executed by a processor, implements the steps of the method according to any one of claims 1-4.
