Process parameter online early warning method based on variance analysis

Abstract

The invention discloses a process parameter online early warning method based on variance analysis and a computer readable storage medium, used for solving the technical problem that the invariabilityof production parameters cannot be found in time in the production process. The process parameter online early warning method based on the variance analysis comprises the following steps: obtaining amonitoring data sample of the process parameters from a production system real-time database; calculating a variance value of the monitoring data sample to characterize fluctuations of the process parameters; generating early warning information of the process parameters based on the preset early warning configuration of the process parameters and the variance value; and pushing the early warninginformation according to a preset early warning graded push mechanism. The process parameter online early warning method based on the variance analysis is based on the real-time data and can performonline continuous analysis and diagnosis on various process parameters, discover hidden dangers, and predict risks; and the graded early warning and push mechanism is used for refining the early warning information and early warning methods, which provides more powerful support for production scheduling management.

Description

technical field [0001] The invention belongs to the technical field of industrial production monitoring, and in particular relates to an online warning method of process parameters based on variance analysis and a computer-readable storage medium. Background technique [0002] Process parameters are important indicators that reflect the safety production status of enterprises. In industrial enterprises such as crude oil extraction, oil refining, and chemical industry, the typical feature of their production and operation is continuous production day and night. The production process mostly uses equipment such as pipelines and containers. The materials complete the physical and chemical processing process during the flow process. Among them, the production process and the flow process The process parameters need to be monitored, especially the pre-adjustment needs to be made according to the changing trend to avoid production stop accidents or safety accidents. [0003] In a...

Problems solved by technology

Once the feed flowmeter of the reactor breaks down and the data of the feed amount remains unchanged, the temperature and pressure of the reactor may fluctuate greatly because the system cannot obtain the correct reaction parameters in time. Variety

As a follow-up device of the reactor, the temperature and pressure of the regenerator will also fluctuate accordingly, which will greatly increase the difficulty of process operation, thereby affecting product quality and even causing accidents
