the WEB server in the area III judges whether the file is successfully received or not by reading the file updating time, the last change time of the file is read every 5 seconds, the file is considered to be successfully received after the file is not changed for 2 seconds, the file is submitted to a file sending area after the file receiving buffer area successfully receives the overhaul file, and the overhaul file can be checked through an ls command;
step 1.5, the application server in the area I analyzes and processes the maintenance information file and sends the maintenance information file to a master control end; the overhaul file in the file sending area can be correctly monitored by the reverse transmission module and transmitted to the I area of the regulation and control system through reverse isolation, the file directory is received in the I area of the regulation and control system, and the file can be viewed through the ls command.
Step 2, the system intelligent analysis matching module intelligently analyzes the overhaul file, and matches corresponding equipment with equipment information according to matching rules, wherein the method specifically comprises the following steps:
step 2.1, after the main control end host receives the maintenance information file, the main control end host analyzes and processes the maintenance information file through a system intelligent analysis matching module, and the standby host analyzes and processes the maintenance information file when the main control end host does not receive the maintenance information file; the maintenance information file adopts an E file standard format, the analysis file adopts an E language analysis standard dynamic library, and the analysis content comprises start time, end time, equipment name, station name, voltage level and maintenance information; the analyzed maintenance information and the file names are stored in an 'maintenance schedule information table', then the table is synchronized to a region III, the region III judges the transmission state by reading the file names in the 'maintenance schedule information table' of a real-time library, if the file exists, the transmission is successful, if the file name does not exist, the transmission is continued, the file is moved to a FAIL directory after 1 hour, real-time warning is carried out, a host is reminded of not correctly receiving the maintenance information file, the warning information complies with the standard of a regulation and control system, can be checked through a real-time warning window, and can be inquired through a historical warning inquiry tool; classifying backup files according to the file transmission state, successfully transmitting the file backup to a SUCCESS directory, unsuccessfully transmitting the file backup to a FAIL directory, and respectively checking the files which are successfully and unsuccessfully transmitted in the SUCCESS directory and the FAIL directory through an ls command; the file with failed transmission is written into the alarm library in the area III, the alarm is sent to the electronic on-duty system through the electronic on-duty interface, and short message alarm is carried out;
step 2.2, intelligently analyzing fuzzy matching equipment for the circulated maintenance information, wherein the plant station name determines the equipment range in an accurate matching mode, and then fuzzy matching of the equipment name is carried out in a mode of extracting keywords of the equipment name;
step 2.3, checking the maintenance information, and marking the maintenance information as unreasonable if the checking time is not accordant with the current time < the starting time < the ending time; if the result is in accordance with the verification result, the verification is passed;
and 2.4, storing the information after passing the verification in a warehouse, and checking an information analysis verification storage result in the maintenance schedule information table through a DBI maintenance tool.
Step 3, visually managing the maintenance information in the master control station, which specifically comprises the following steps:
step 3.1, opening a maintenance information management interface through a master control end host or an input terminal command;
step 3.2, after the user name and the password are correctly logged in, checking whether the user has the license hanging authority, if so, entering step 3.3 to carry out maintenance information management operation, and if not, reminding that the user does not have the management authority and cannot operate;
step 3.3, carrying out maintenance information query according to listing time, picking time, planned maintenance starting time, planned maintenance finishing time, station and state, wherein the query result display field is as follows: the system comprises a maintenance ID, a station, a voltage grade, an equipment name, a planned maintenance starting time, a planned maintenance finishing time, a listing time, maintenance information and a state, and supports sequencing;
and 3.4, manually modifying the information with inaccurate intelligent analysis fuzzy matching result through the retriever, deleting the selected overhaul information through right key operation, and only marking the data as deleted without deleting the data in the database.
Step 4, analyzing the maintenance information by a tile hanging and picking feasibility analysis module, and automatically hanging and picking the tiles based on the analysis result, wherein the method specifically comprises the following steps:
4.1, analyzing the maintenance information by a hang-off card feasibility analysis module, performing hang-off card feasibility analysis after the starting time of maintenance operation in a waiting execution state is reached, and modifying the state to be in execution if the maintenance operation is feasible and the hang-off card is already hung; if the operation is feasible and the card is not listed, submitting the card listing request of the corresponding equipment to a regulation and control system; if the card is not hung after the time exceeds 15 minutes after the starting time is reached, sending an alarm;
step 4.2, for the maintenance operation in the 'execution' state, after the end time is reached, if the cards have been picked, the modification state is 'execution end'; if the cards are not picked, comprehensively judging whether records of the same equipment with time overlap exist, submitting a card picking request of the corresponding equipment to a regulation and control system if the records of the same equipment with time overlap do not exist, and only modifying the state to be 'execution end' if the records of the same equipment with time overlap exist; if the card is not picked after the ending time is reached and the time exceeds 15 minutes, sending an alarm, and checking the operation alarm through an alarm window of a regulation system;
and 4.3, searching the historical alarm records through alarm inquiry.
The invention improves the working efficiency of completing the plate hanging and picking operation during the maintenance of the power equipment, reduces the error rate of manual operation, avoids the interference of abnormal data such as error remote signaling, mutation remote sensing and the like generated by a regulation and control system in the maintenance process of the equipment on the monitoring work of a power grid, and improves the safety of the maintenance process of the equipment.
