8. The system of claim 7, further comprising:
the early warning module is used for sending power failure early warning short message notification to users of all power utilization types affected in the power failure early warning event according to the visual display result; dispatching the terminal equipment in the power failure state according to the calling result, and sending the generated fault report to emergency repair personnel for emergency repair operation;
the visualization module is used for associating the blackout equipment information and the blackout time information included in the blackout early warning events with blackout events in a blackout city to obtain an association relation, and visually displaying the blackout early warning events on a blackout map;
and receiving a query instruction input by a user and used for querying the power failure information of any power failure early warning event in the power failure map, acquiring the power failure information of the power failure event in the power failure fair which is associated with the power failure early warning event corresponding to the query instruction according to the query instruction and the association relation, and outputting and displaying the power failure information.
9. The system of claim 8, wherein the visualization module is further configured to obtain a terminal device affected by the power outage early warning event, obtain a terminal device corresponding to the power outage early warning signal that cannot be combined, associate the terminal device affected by the power outage early warning event or the terminal device corresponding to the power outage early warning signal that cannot be combined with the terminal device affected by the power outage event according to a power supply line or an influence time, and screen the terminal devices on the same line or influencing the same time to associate with each other, so as to generate an association relationship.
10. The system of claim 9, wherein the visualization module is further configured to display the associated terminal device on the power line, display a power outage pre-alarm event present on the power line, and display the power outage pre-alarm event in association with the associated terminal device.
