Research On Optimized Design Of Alarm System Performance Based On Data Analysis

In the production process of processing industrial,monitoring of process safety alarm system is very important.Once the alarm system performance is not enough,it is easy to appear a large number of abnormal alarm and nuisance alarm and alarm flood happe n frequently,leading to accident appear constantly,production safety is also affected by the extremely serious.Therefore,comprehensive and effective evaluation of the performance of the alarm system and the performance of the alarm system is optimized in the alarm system is particularly important in many research fields.At present,the alarm system mainly USES the traditional performance evaluation aspects according to the existing basic indicators and the evaluation of foreign standards for mechanical calculation,or based on experience to judge the alarm system performance;In the field of alarm system performance optimization,mainly from the aspects of law of certain type of alarm and alarm analysis.Existing method without considering the scope covered with alarm system in addition to the traditional sense of automation machinery and equipment system,and the role of personnel factor and management factor;While the study of alarm system performance optimization without considering the alarm system itself have intrinsic functions such as alarm inhibition,research achievements in production implementation Angle has the certain difficulty,and the research content is usually not directly effective solve the most need to solve problems in the process of production,especially the existing inhibiting strategy research does not consider the need to curb when the problem such as the characteristics of the alarm.In this paper,firstly analyze the alarm system performance evaluation of the existing indicators,on the basis of summarizing the existing effective alarm system evaluation index,the analysis of these indicators associated with each part of the alarm system and effect relationship,then indicators related to the specific topic through a certain algorithm,put forward the new alarm system design specific elements of evaluation index,in particular,to the existing quantitative influence factors of key performance indicators(KPI)is analyzed,and their contact with the operator response performance,on the basis of building an operator response calculation formula of the performance comprehensive evaluation of quantitative indicators.With field alarm system data to evaluate effect of proof test.On the basis of the alarm system performance evaluation indicators analysis software is designed.And then studied the inhibition of alarm system strategy,due to lack of inhibition in the existing alarm system related research strategy based on state of alarm and related research,existing alarm suppression method problem such as the lack of integrity and systemic,so design and puts forward a new static alarm control strategy.On the basis of studying the existing alarm inhibition,summarize and put forward the definition and characteristics of static/dynamic alarm suppression strategy,combines sorting and data filtering,based on data driven static alarm suppression strategies,due to production,in order to solve the false-negatives problems caused by the change of state,enhances the working efficiency of the alarm system.
