the early warning event module is used for combining the power failure early warning signals to obtain a plurality of power failure early warning events; if any one of the power failure early warning signals does not meet the preset condition, the power failure early warning signal is used as a power failure early warning event; the preset conditions are that at least two power failure equipment with power failure early warning signals are identical, and the power failure time interval is smaller than the preset interval;
The recall operation module is used for carrying out recall operation on the power failure equipment corresponding to the power failure early warning event so as to obtain three-phase current information of the power failure equipment; and judging whether the calling operation is successful or not, and if so, judging whether the corresponding power failure equipment is in a normal working state according to the comparison result of the obtained three-phase current information and the preset threshold value; if the corresponding power failure equipment is in a normal working state, generating prompt information of normal power supply of the power failure equipment and outputting the prompt information; if the corresponding power failure equipment is in a power failure working state or fails in recovery, generating dispatching processing information, and sending the dispatching processing information to a client of a rush-repair person so as to inform the rush-repair person to go to the field to carry out rush-repair processing on the power failure equipment;
The early warning module sends a power failure early warning short message notice to users of all power utilization categories influenced in a 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 a rush repair person for rush repair operation;
The visualization module is used for associating with the power failure events in the power failure bazaar to obtain association relations according to the power failure equipment information and the power failure time information included in the power failure early warning events, and carrying out visual display on the power failure early warning events on a power failure map;
Receiving a query instruction which is input by a user and is used for querying power failure information of any power failure early-warning event in a power failure map, acquiring power failure information of a power failure event in a power failure bazaar 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;
The visualization module is further used for acquiring terminal equipment affected by a power failure early warning event, acquiring terminal equipment corresponding to a power failure early warning signal which cannot be combined, associating the terminal equipment affected by the power failure early warning event or the terminal equipment corresponding to the power failure early warning signal which cannot be combined with the terminal equipment affected by the power failure event according to a power supply line or influence time, screening the terminal equipment in the same line or influence time, and associating the terminal equipment with the terminal equipment in the same line or influence time to generate an association relation.
5. The system of claim 4, wherein the visualization module is further configured to display an associated terminal device on the power line, display a power outage early warning event present on the power line, and display the power outage early warning event in association with the associated terminal device.
