Abstract

The invention relates to a petrochemical process alarm system adaptive dead zone setting method based on multi-source data, which mainly solves the problems of inaccurate alarm information, manual adjustment and poor safety in the prior art. The present invention adopts a petrochemical process alarm system adaptive dead zone setting method based on multi-source data, including the construction of a real-time collection platform for multi-source data of the device, the collection of device operation account data, data preprocessing, operation account analysis, Calculation of adaptive dead zone range, alarm system with adaptive dead zone setting, real-time collection of data collected by the platform and data collected by the operation account data acquisition server After preprocessing, the operation account data is analyzed, and the target data The technical scheme of setting the dead zone in the alarm system with adaptive dead zone setting can better solve the above problems, and can be used in the petrochemical process alarm system adaptive dead zone zone settings.

Description

technical field [0001] The invention relates to a petrochemical process alarm system adaptive dead zone setting method based on multi-source data. Background technique [0002] The complex working conditions in the petrochemical production process have the characteristics of nonlinearity, strong coupling, multi-scale, multi-mode, dynamic time-varying, etc., which put forward higher requirements and challenges for process safety assurance and product quality control. Abnormal working conditions in the petrochemical production process have the characteristics of strong concealment, many related factors, and great harm. Once misjudgment or misoperation occurs, it is easy to cause production fluctuations or even unplanned shutdowns. Most of the monitoring and early warning methods remain at the level of relying on manual experience to analyze and deal with. Due to the influence of various objective interference factors and the level of operators, it is difficult to quickly and a...
