Property is estimated, and the analysis result of artificial intelligence is realized according to the big data for having stored, it is ensured that Operation of Electric Systems safety, and
And O＆M decision-making is formulated by the assessment to transformer life in time, reduce failure risk.
Cloud Server formulates maintenance decision according to transformer assessment result, determine transformer maintenance and renewal it is optimal
Time.User can judge whether to need to update or repair according to the assessment result of system, if desired just can be according to reality
Situation, selection is updated or repairs at the maintenance influence minimum time point that has a power failure, it is to avoid transformer fault causes just bad
Influence.Alarm record is produced when cloud server is to abnormal real-time status data, by abnormality alarming information and the use of correlation
After the analysis and evaluation result of family customization is encrypted encapsulation, it is pushed to pre-defined wiredly and/or wirelessly O＆M client and sets
It is standby.O＆M client can also carry out predefined setting to required evaluation result content, and O＆M client can be with
Sent to Cloud Server by encryption channel and actively patrol and examine instruction, if routine monitoring, can set by O＆M client
The frequency of the real-time data acquisition of monitoring terminal or cycle, and timing mitigates the work of personnel control to O＆M client feedback
Also ensure the monitor in real time to transformer while amount, improve safety precaution effect.
The web service module requirement Cloud Server that user can also be provided by Cloud Server is actively patrolled and examined designated equipment
And the real-time status data required for obtaining.And then realize the collection of more accurate transformer information and the monitoring of state.Have
Line and/or wireless O＆M client device are by after the warning information and O＆M information that encryption channel receives Cloud Server push
Carry out data deciphering and be presented to user.
Remote signalling：It is required that using without source contact mode, i.e. the input of certain remote signalling amount all the way should be a pair of contacts of relay, or
Person is closure, or is disconnected.The closure of relay contact or disconnection are converted into by low level or height by remote signalling terminal board
