if the sub-station generates channel sending direction alarm, the receiving link between the main station and the sub-station is interrupted, the communication side alarm is analyzed, if the communication side has no alarm, the sub-station and other stations perform positioning through the alarm to obtain the position of the channel fault;
if the substation has no channel alarm, if the communication side has alarm, the substation generates channel to receive and send the direction alarm; if the communication side has no alarm, the sub station and other stations alarm to carry out positioning to obtain the position of the channel fault.
8. A safety and stability control system channel fault positioning system based on full link alarm is characterized by comprising:
an acquisition module: the device is used for acquiring alarm information of a safety and stability control device and a channel between the devices;
a system building module: the safety and stability control system is constructed based on the acquired alarm information;
a normalization processing module: the alarm processing device is used for carrying out standardized processing on the acquired alarm information according to the alarm classification obtained in advance to obtain processed alarm information;
an analysis module: and the method is used for analyzing the processed alarm information by adopting a preset channel fault decision tree based on a safety and stability control system to obtain the position of the channel fault.
9. A safe and stable control system channel fault positioning device based on full link alarm is characterized by comprising a processor and a storage medium;
the storage medium is used for storing instructions;
the processor is configured to operate in accordance with the instructions to perform the steps of the method of any of claims 1 to 7.
10. Computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 7.
