Embodiment 1

[0032] Example 1: see figure 1 , a data-driven abnormal slice management method for chemical production, the method comprising the following steps:

[0033] Step 1: Use the sensor to realize the collection of various parameters;

[0034] Step 2: Correlation calculation, conduct periodic correlation analysis on the bit number, and obtain the correlation matrix at different times; the specific calculation method is as follows,

[0035] In the normal production process, periodically calculate the tag that is strongly related to the target tag and form a related tag group, for example, calculate the tag that is strongly related to the A.WL.MT.LT901A tag, then use the correlation coefficient algorithm Calculate other digit numbers that have a greater correlation with the change of A.WL.MT.LT901A, denote A.WL.MT.LT901A by x, and y refers to other k digit numbers involved in the correlation calculation. First calculate the correlation coefficient between x and y x=[x1,x2,x3,...xn]...

Abstract

The invention relates to an abnormal section management method in chemical industry production based on data driving. The method comprises the following steps of 1, collecting each bit number by usinga sensor; 2, analyzing periodical correlation on the bit number, to acquire correlation matrixes at different moments; 3, at the certain moment, giving an alarm by the target bit number, and findingthe correlation matrix closest to the alarm moment through time difference; 4, computing the similarity between the correlation matrixes and historical correlation matrixes, to acquire the historicalcorrelation matrix set with the highest similarity; 5, calling a historical operation corresponding to the most similar historical correlation matrix, and sending the same to an operation staff; and 6, after the alarm is solved, recording to the correlation matrixes and the operation records of the operation staff to form into knowledge sections, and putting the knowledge sections into a historical database. According to the method, the defect of traditional single alarm information is avoided, the correlation parameter of the alarm parameter is found via computation of the correlation matrix,and the operation staff can acquire more decision making bases and operation bases according to the correlation parameter.

Description

technical field [0001] The invention relates to a slice management method, in particular to a data-driven abnormal slice management method in chemical production, which belongs to the technical field of chemical production control. Background technique [0002] The chemical production process is a high-risk process with many parameters. The operator needs to stay in the control room and observe the parameters in real time according to the DCS system interface to keep abreast of the changes in production conditions. This traditional management operation is limited by time and place, and is relatively passive. powerful. The process of chemical production is complicated due to many parameters, diverse processes, and it is necessary to provide operators with flexible technical operation solutions to cope with the complex and changeable chemical production process. [0003] At present, the main method of tag management is that the operator observes the DCS interface and receives...
