According to being applied not only to Centralized Monitoring, in addition it is also necessary to online data is carried out digging utilization, for operation system, DSS service.
The variable data concentrated collection that this each plant stand arbitrarily defines to together, be difficulty with standardization represent, general relative analysis,
Statistical summaries, comprehensive analysis etc. are conventional such as software function.
Such as, the same online data of each water factory same process node device is different variablees, can not be by solid during data separate
Set pattern then random query analysis, and need the configuration of variable one by one, when plant stand is increased or decreased, in addition it is also necessary to reconfigure,
Can not automatically access or reject.Multiple factory station data contrast can not be carried out by one variable of arbitary inquiry when data query.
(5) cannot be carried out data prediction: based on configuration software function and industry storehouse variable storage mechanism, configuration software and
The data prediction such as DTU/RTU can not hold before acquisition and realize complicated formulas calculating, data statistics collects, characteristic extraction
Function.
