Problems solved by technology
[0002] The current factory early warning method mainly manages the alarms that have occurred, so as to reduce nuisance alarms and reduce alarm floods. It is a passive management and cannot achieve predictive management.
Factory personnel cannot know potential faults, so they cannot deal with faults in time, which seriously affects the economic benefits of the factory

Embodiment approach
[0067] As an implementation, the early warning model variables may include:
[0068] Input variables (independent dependent variables that can be read in from DCS or other control / instrumentation systems), X=(X 1 ,X 2 ,...,X n ), n is the number of input variables.
[0069] Early warning model output variables (dependent fruit variables, also known as alarm variables)
[0070] Y=(y 1 ,y 2 ,...,y m ), m is the number of output variables.
[0071] Manipulated variable (independent dependent variable that can be read from DCS or other control / instrumentation system), MV=(mv 1 ,mv 2 ,...,mv i ), i is the number of operand variables.
[0072] Control output variable (dependent fruit variable)
[0073] CV=(cv 1 ,cv 2 ,..., cv j ), j is the number of control variables.
[0074] For example, if the factory equipment is a factory liquid level tank, in general scenarios, the operating parameters of the factory liquid level tank can include the inlet flow F 1 , the outlet...

The embodiment of the invention provides a factory early warning implementation method, apparatus and system. The factory early warning implementation method includes the steps: acquiring early warning model variables, at the current moment, sent from a factory control system, wherein the early warning model variables include an input variable and an output variable of target factory equipment; inputting the early warning model variables into a control dynamic model, and calculating the prediction control output variables of a plurality of following moments; inputting the prediction control output variables and the early warning model variables into an early warning dynamic model, and calculating the corresponding plurality of moments of prediction input variables and prediction output variables; and according to the following plurality of moments of prediction input variables and prediction output variables, sending an early warning prompt to a user terminal. The factory early warning implementation method, apparatus and system can efficiently determine or predict the potential faults of factory equipment or technology so as to prompt factor staff to timely process the faults to reduce non-planned safety accidents and improve economic benefits of factory.
Description
technical field [0001] The invention relates to the field of factory early warning, in particular to a method, device and system for realizing factory early warning. Background technique [0002] The current factory early warning method mainly manages the alarms that have occurred, so as to reduce nuisance alarms and reduce alarm floods. It belongs to passive management and cannot realize predictive management. Factory personnel cannot know potential faults, so they cannot deal with them in time, seriously affecting the economic benefits of the factory. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a method, device and system for implementing factory early warning, which can efficiently judge or predict potential factory equipment or process failures, so as to remind factory personnel to deal with failures in time, Reduce unplanned safety accidents and improve p...
