and if the abnormal signal does not cause the device to be locked, the device has no correlation model and does not influence the operation of the device, and the priority of the abnormal processing is general.
For example, after the "a position signal abnormality" occurs, it is determined according to S2-1 that the apparatus is not locked, and the abnormality configures a correlation element model, and the abnormality type is acquisition abnormality, and it is determined that the primary equipment element a is correlated, and further it is determined through a policy influence range that all policy functions of the abnormality influencing apparatus need to remind a scheduling operator that the apparatus policy determination is influenced, and emergency processing is needed.
Taking the error-proof check abnormality of the safety and stability control device as an example, one abnormality of the device is described as a 'constant value check abnormality', the type of the abnormality is the error-proof check abnormality, and whether the locking attribute is yes or not is judged.
After the 'fixed value check abnormity' occurs, judging that the device is locked according to S2-1, entering S2-4, judging that the device is locked due to the abnormity occurrence, judging that the processing priority of the abnormity is urgent, and immediately informing a scheduling operator to process the abnormity of the device.
Taking a channel abnormality of the safety and stability control device as an example, one abnormality of the device is described as "communication abnormality with the station B", the type of the abnormality is channel abnormality, whether the locking attribute is negative or not is judged, and the abnormality configures an associated channel model.
After the communication abnormity with the station B occurs, judging that the device is not locked according to S2-1, and entering S2-2; confirming the associated model configuration, and entering S2-3-2; the signal belongs to the device channel abnormity, which can cause the device to judge the policy logic or the execution is influenced, the processing priority of the abnormity is judged to be urgent, and the scheduling operator needs to be informed immediately to process the device abnormity.
Taking other anomalies of the safety and stability control device as an example, one anomaly of the device is described as 'GPS signal anomaly', the type of the anomaly is other anomalies, and whether the locking attribute is negative or not is judged.
After the GPS signal is abnormal, judging that the device is not locked according to S2-1, entering S2-2, confirming that no associated model configuration exists, and not influencing the operation of the device when the abnormal signal occurs; and S2-4, judging the processing priority of the abnormity to be general, and requiring a scheduling operator to inform an operation maintenance operator to carry out subsequent processing on the device abnormity.
