This method has overcome the most of not enough of instrumentation record.Can use various means of communications to take the instrument communication of various communications protocol and multiple manufacturer, it is all higher to expand maintainability.But because this type of software only is used for the record accident, data show means and rich data analytical method so it lacks flexibly, also lack control device effectively.It often needs to cooperate the monitoring of finishing jointly production process with other software.
Summary of the invention
For the accident occurrence cause in the analytical industry production, must note the related data in this accident surrounding time, a series of data variation trend during accident analysis in the dynamically demonstration accident generation surrounding time are carried out comprehensive analysis and judgement thereby be convenient to the user, obtain correct conclusion.The purpose of emergency review and playback promptly is this.It provides the means of a kind of effective analysis accident and diagnosis accident.
To achieve these goals, the present invention adopts following technical scheme, comprises the steps:
The emergency review point of recollecting for needs and recollect data and be configured.These emergency review points and recollect data and all be taken from the computer supervisory control system real-time data base are responsible for the collection of data and are refreshed by supervisory control system.
Read the emergency review dot information according to configuration information, from real-time data base, obtain relevant data value.And the real-time tracking accident point, data recollected in record, and accident finishes the back and forms complete emergency review data slice, stores historical data base into.
Selection needs to analyze the clauses and subclauses of checking in the accident that has taken place, and the relevant historical data of inquiry demonstrates the tabulation of accident front and back data variation value and curve and all switching value displacements and the out-of-limit incident of analog quantity then.If adopt play mode to check, then the result that slowly will inquire according to playing progress rate shows, and is omnidistance thereby simulated accident takes place.
By the emergency review function is embedded in the real-time data base, can save cost and enhancement function to greatest extent.The present invention has overcome the deficiencies in the prior art, combines controlling to the record analysis of accident with to the supervision of industrial processes.Because real-time data base has configuration means and the higher maintainability expanded flexibly, so the maintenance of emergency review is also become simple.The real-time data base of supervisory control system just well provides the support to emergency review.
