Data, which are called together, surveys the main acquisition and parsing realized to acquisition terminal electricity consumption data, including instantaneous voltage, transient current,
It is positive/negative to active energy and end message (terminal address code, terminal address, producer etc.).
2, fault alarm:
Fault alarm module mainly realizes the function that multiplexing electric abnormality automatic failure alarm is reminded, the alarm form of automatic alarm
There are the modes such as image alarm, word alarm, SMS alarm and Email alarm.
The technical program is mainly showed in the form of word alarm, the multiplexing electric abnormality of alarm be mainly electric energy meter stop walking,
Under-voltage abnormal, full decompression exception, disconnected mutually exception, undercurrent are abnormal and stop abnormal etc. abnormal.
3, data sheet:
Data sheet function be mainly realize to data information check and the statistical analysis of data etc., include anomaly statistics
And analytical statement.
4, system administration:
System administration mainly includes system clock synchronization, rights management, exception management and safety management etc..
1) system clock synchronization is to guarantee the error of special transformer terminals and platform, platform and standard Event no more than 3 seconds；
2) rights management is the configuration and management of the user role and permission used platform；
3) exception management is to carry out setting management to the multiplexing electric abnormality type of automatic alarm, including Exception Type and criterion
Setting；
4) safety management be platform should have operation log, data reasonableness test, data it is automatic or manual backup and it is extensive
The security functions such as multiple.
Multiplexing electric abnormality automatic alarm platform realizes the real-time early warning of Electricity customers multiplexing electric abnormality and the intelligence of fault type
Diagnosis, provides judgment basis and data supporting for engineers and technicians scene defect elimination, and acquisition is improved from technological means eventually
Hold defect elimination efficiency.From business, management view, department of linked groups is set up, it is ensured that the normal operation of automatic alarm platform；It is excellent
Change terminal defect elimination workflow, and formulate job rating standard, it is horizontal to promote defect elimination work management.
Fig. 3 gives defect elimination flow diagram of the invention.
Fig. 4 gives defect elimination process organization configuration diagram of the invention.
Wherein, the function of each function group and effect are as follows:
1, power information acquisition group:
1) it is responsible for the daily maintenance to alarm platform, it is ensured that terminal is online, and data acquisition holds water；
2) it is responsible for the monitoring to the warning message of alarm platform, worksheet processing is carried out to the terminal of multiplexing electric abnormality；
3) it is responsible for the processing result fed back to each teams and groups and processing work order carries out unified filing management；
4) it works each teams and groups' defect elimination and carries out job rating.
2, customer service group:
1) work order issued according to power information acquisition group, sends supervision of power consumption to be checked to scene, appraises and decides fault type
And reason；
2) fault type determined according to scene delivers related teams and groups and eliminates failure, and carries out process tracking；
3, power utility check group:
1) the doubtful stealing user found after checking for supervision of power consumption scene carries out site inspection, is such as implicitly present in stealing
Situation is carried out in accordance with regulations processing and imposes a fine, and records processing result；
2) processing result at the appointed time, is fed back into power information acquisition group；
4, dress table connects electric group:
1) electrical energy meter fault found after checking for supervision of power consumption scene arranges personnel to carry out meter exchange, fills in work
Make single；
2) processing result at the appointed time, is fed back into power information acquisition group；
5, other marketing teams and groups:
The device end failure defect elimination work being responsible for other than electrical energy meter fault and electricity stealing, and by defect elimination result and work order
Feed back to power information acquisition group.
From the defect elimination process illustrated:
1. power information acquisition group passes through alarm platform daily checks multiplexing electric abnormality warning message；
2. power information acquisition group finds that there are abnormal alarms such as in platform, according to multiplexing electric abnormality type, analysis is sentenced
Disconnected terminal fault type, and the Electricity customers relevant information (family number, table number, voltage, electric current etc.) of alarm is recorded, work order is generated,
Customer service group is assigned to be handled；
3. customer service group assigns supervision of power consumption to check to scene according to work order, to turning again the problem of actually encountering on site
Relevant departments are handed over to be handled, in which:
It was found that live decompression, defluidization or disconnected phase, and without other abnormal, other battalion are delivered in the corresponding electricity charge of subsequent collection
Sell teams and groups' processing；
It was found that there is stealing suspicion, delivers power utility check and (oppose electricity-stealing) group；
Electric energy meter stops walking, meter failure, delivers dress table and connects electric group；
4. each teams and groups carry out in-situ processing, record processing work order to terminal fault, and processing result is fed back to and uses telecommunications
Cease acquisition group；
5. power information acquisition group carries out relevant issues processing record, convenient for the dimension from now on for special transformer terminals and meter
Shield.
For management above, the examination of terminal defect elimination work is provided as follows:
1) in one month after issue handling of same meter and terminal, alarm should not occurs again；Such as go out in one month
It now alarms three times and more than three times, customer service group supervision of power consumption related responsibility should be investigated；
2) occurs abnormal alarm every time, it is necessary to fault message be notified into supervision of power consumption on the day of, otherwise investigate and use telecommunications
Cease acquisition group related responsibility；
3) abnormal alarm must not exceed 3 working days to the time cycle eliminated extremely every time；If you need to mileometer adjustment or subsequent anti-
Stealing action, interim reply should be done within 3 working days；As do not replied on time, the responsibility of relevant treatment teams and groups is investigated；
4) warning message and scene are not inconsistent actually, are responsible for system maintenance by power information acquisition group.
