Detailed Description
The invention will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.
The embodiment provides a method for analyzing reasons for abnormal sintering process, as shown in fig. 1, the method comprises the following steps:
101. And determining abnormal parameters and abnormal moments of the quality of the sintering state.
The sintering process state quality parameters corresponding to the sintering mineral quality are obtained, the sintering process state quality parameter data are obtained in real time, and whether the sintering process state quality parameters have abnormal sintering state quality parameters or not is monitored in real time according to the sintering process state quality parameter data, so that the analysis and adjustment can be quickly made, and the increase of energy consumption and the reduction of the production quality in the sintering process are avoided.
The abnormal time refers to the time when the abnormal parameters of the sintering state quality exist in the parameters of the sintering process state quality.
102. And acquiring sintering operation parameters related to the first preset of the sintering state quality abnormal parameters, determining a sintering operation period to be analyzed according to the abnormal time, and acquiring sintering state quality abnormal parameter data and sintering operation parameter data corresponding to the sintering operation period.
For example step 101, the abnormal time is determined because example step 102 determines the sintering operation time period to be analyzed according to the abnormal time, and since the sintering process has the characteristics of long time delay, multiple influencing factors and strong parameter coupling, i.e. the operation error may not appear abnormal in the state quality parameter of the sintering process, but only appears abnormal after a time period, the data of the time period of the sintering operation time period, rather than the data of the time point of the abnormal time, needs to be analyzed, so that the abundant information in the big data is mined, and the accuracy of analysis of the abnormal reason of the sintering process is improved.
Wherein, the first preset correlation refers to selecting the first preset number from the correlation ranks, or selecting the sintering operation parameters with the correlation values larger than the first preset value. Since the determination of the sintering state quality abnormality parameter is performed in real time, the acquisition of the sintering operation parameter related to the first preset of the sintering state quality abnormality parameter is also performed in real time based on the sintering state quality abnormality parameter.
Wherein the determination of the sintering operation period may be preset, for example, the sintering operation period is the first two same days from the start of the abnormal time. For obtaining the sintering state quality anomaly parameter data and the sintering operation parameter data corresponding to the sintering operation period, it should be noted that the sintering operation period is formed by a plurality of sintering operation moments, and therefore obtaining the sintering state quality anomaly parameter data and the sintering operation parameter data corresponding to the sintering operation period includes: and acquiring sintering state quality abnormal parameter data and sintering operation parameter data corresponding to each sintering operation time, wherein the sintering operation time, the sintering operation parameter data of at least one sintering operation parameter and the sintering state quality abnormal parameter data of at least one sintering state quality abnormal parameter can be listed in a table form as an implementation mode.

As an embodiment, the target sintering operation parameter section may include a sintering operation parameter section having a forefront order with respect to the sintering state quality abnormality parameter section, which is not limited herein.
For example, one abnormal sintering state quality parameter is included, the abnormal sintering state quality parameter interval is [ a, B ], three sintering operation parameters are a, B and c respectively, the sintering operation parameter interval corresponding to the sintering operation parameter a is a1, a2 and a3, the sintering operation parameter interval corresponding to the sintering operation parameter B is B1, B2 and B3, the sintering operation parameter interval corresponding to the sintering operation parameter c is c1 and c2, the related sequence is a1 greater than a2 greater than a3, B1 greater than B2 greater than B3, and c1 greater than c2, and the target sintering operation parameter interval may be the sintering operation parameter interval a1, the sintering operation parameter interval B1 and the sintering operation parameter interval c1 which are the forefront in the related sequence corresponding to each sintering operation parameter.
Because the sintering state quality abnormal parameter data and the sintering operation parameter data come from the actual data information of the on-site production line, the information sources are real, and the target sintering operation parameter interval corresponding to the sintering state quality abnormal parameter interval is determined based on the sintering state quality abnormal parameter data and the sintering operation parameter data, the embodiment can accurately trace the abnormal target sintering operation parameter and the abnormal target sintering operation parameter interval, thereby improving the analysis accuracy of abnormal reasons in the sintering process.
104. Analyzing abnormal reasons of the sintering process according to the sintering state quality abnormal parameter interval and the target sintering operation parameter interval.
For the steps of this embodiment, since the reasons for the abnormality are the target sintering operation parameter and the target sintering operation parameter interval, the further reasons for the abnormality in the sintering process, that is, the reasons for the abnormality in the sintering process, can be analyzed based on the target sintering operation parameter and the target sintering operation parameter interval, and the positioning is not needed manually according to experience, thereby improving the efficiency and accuracy.
Compared with the prior art that manual monitoring is needed and manual judgment is needed for sintering state quality abnormal parameters, the sintering process abnormal reason analysis method, device and equipment provided by the application have the beneficial effects that whether the sintering process state quality parameters are abnormal or not is automatically analyzed, so that manual monitoring is not needed, the sintering state quality abnormal parameters are not needed to be judged manually, the real-time performance, the efficiency and the accuracy of sintering process abnormal reason analysis are improved, the labor cost is reduced, the sintering operation parameters related to the first preset of the sintering state quality abnormal parameters are acquired, the sintering operation time period to be analyzed is determined according to the abnormal time of the sintering state quality abnormal parameters, so that real information is acquired from a large amount of rich production line data in the time period, after a large amount of production line data are acquired, the information can be mined from the large amount of production line data, and the mined information comprises: compared with the prior art that a large amount of production line data can only be analyzed through manual experience, the method has subjectivity, and the analysis efficiency of the large amount of data is low, and is difficult to accurately and quickly position the reasons for causing the abnormal parameters of the quality of the sintering state.
Further, as a refinement and extension of the specific implementation of the foregoing embodiment, for a complete description of the specific implementation process in this embodiment, another method for analyzing the cause of abnormal sintering process is provided, as shown in fig. 2, which includes:

Specifically, the whole sintering production line process may be divided into stages having a process sequence, each stage obtaining a sintering process state quality parameter related to a second preset of the sinter quality, for example, the whole sintering production line process may be divided into stages 1, 2, and 3 having a process sequence.
For the embodiment, because the whole process of the sintering production line is obtained instead of only monitoring a certain key process parameter, the analysis of the abnormal reasons of the sintering process is more comprehensive and can not be omitted, thereby ensuring the analysis accuracy of the abnormal reasons of the sintering process.

The corresponding evaluation score of the sintering process state quality parameter data can be a corresponding relation between preset sintering process state quality parameter data and evaluation score according to expert experience or data analysis, so that when the sintering process state quality parameter data is acquired, the evaluation score can be automatically determined according to the sintering process state quality parameter data, the higher the evaluation score is, the more the sintering process state quality parameter data accords with the expectations of field operators, as an implementation mode, the sintering state quality abnormal parameter is determined according to the current time evaluation score and the last time evaluation score, specifically, the current time evaluation score and the last time evaluation score of the same sintering process state quality parameter are compared, the sintering process state quality parameter is ranked according to the degree of failure, the failure percentage in the sintering process state quality parameter is identified to be greater than a preset threshold value, the sintering state quality abnormal parameter is identified, the identification of the sintering state quality abnormal parameter is the dynamic identification by fusion of field experience and data analysis, the identification range is wide, and the adaptability and the interpretability of the production line are strong.
202. And acquiring sintering operation parameters related to the first preset of the sintering state quality abnormal parameters, determining a sintering operation period to be analyzed according to the abnormal time, and acquiring sintering state quality abnormal parameter data and sintering operation parameter data corresponding to the sintering operation period.
For the embodiment steps 201 and 202, the calculation of the first preset correlation and the second preset correlation may be performed based on the correlation analysis, specifically, a common correlation analysis method: (1) correlation coefficient analysis: to measure the strength and direction of the relationship between the two variables. Common correlation coefficients include pearson correlation coefficients, spearman correlation coefficients, and kendel correlation coefficients. (2) regression analysis: model relationships between one or more independent variables and dependent variables are established and described, and correlations between the independent variables and the dependent variables are estimated by fitting regression equations. (3) factor analysis: to explore hidden structures or patterns in a dataset, correlations between variables are determined by identifying common factors.

(2) hierarchical clustering (HIERARCHICAL CLUSTERING): by continuously merging or splitting samples to construct a hierarchical cluster structure, the cluster structure can be of a condensation type (from bottom to top) or a split type (from top to bottom). (3) DBSCAN (Density-Based Spatial Clustering of Applications with Noise): the high-density region is divided into clusters based on the density of the samples, and noise points can be identified.

If the number of abnormal parameters of the sintering state quality is one, as an implementation manner, the determining the target sintering operation parameter interval according to the related sequence includes: and determining a third preset related sintering operation parameter interval corresponding to each sintering operation parameter as a target sintering operation parameter interval. The third preset correlations refer to a third preset number before selection in the correlation sequence, or sintering operation parameter intervals with correlation values greater than the third preset values are selected.
For example, one abnormal sintering state quality parameter is included, the abnormal sintering state quality parameter interval is [ a, B ], three sintering operation parameters are a, B and c respectively, the sintering operation parameter interval corresponding to the sintering operation parameter a is a1, a2 and a3, the correlation sequence is a1 greater than a2 greater than a3, the sintering operation parameter interval of the sintering operation parameter B is B1, B2 and B3, the correlation sequence is B1 greater than B2 greater than B3, the sintering operation parameter interval of the sintering operation parameter c is c1 and c2, the correlation sequence is c1 greater than c2, the target sintering operation parameter interval can be the first two sintering operation parameter intervals a1 (first order) and a2 (second order) of the correlation sequence corresponding to each sintering operation parameter; sintering operation parameter intervals b1 (first order), b2 (second order); sintering operation parameter intervals c1 (first order), c2 (second order).
If the number of abnormal parameters of the sintering state quality is greater than one, as another embodiment, the determining the target sintering operation parameter interval according to the related sequence includes: determining a fourth preset related sintering operation parameter interval corresponding to each sintering operation parameter of each sintering state quality abnormal parameter, and taking intersection of the fourth preset related sintering operation parameter intervals of the same sintering operation parameter of all the sintering state quality abnormal parameters according to a preset rule to obtain a target sintering operation parameter interval. The fourth preset correlations refer to a fourth preset number before selection in the correlation sequence, or sintering operation parameter intervals with correlation values greater than the fourth preset value are selected. Specifically, the following is a first and second examples.
First: taking the example that the previous fourth preset number of each sintering operation parameter is 1, that is, the sintering operation parameter interval related to the fourth preset is the most related sintering operation parameter interval, for example, two sintering state quality abnormal parameters are main negative pressures (the sintering state quality abnormal parameter interval is the main negative pressure a, the main negative pressure B), the sintering operation parameter interval corresponding to the main negative pressure is the end temperature (the sintering state quality abnormal parameter interval is the end temperature a, the end temperature B), three sintering operation parameters corresponding to the main negative pressure are respectively a, B and c, at least one sintering operation parameter interval corresponding to each sintering operation parameter is obtained, specifically, the sintering operation parameter interval of the sintering operation parameter a is a1, a2 and a3, the related sequence is that a1 is larger than a2 and is larger than a3, the sintering operation parameter interval of the sintering operation parameter B is B1, B2 and B3, the related sequence is that B1 is larger than B2 and is larger than B3, the sintering operation parameter interval of the sintering operation parameter c is c1 and c2, and the related sequence is c1 is larger than c2, and the sintering operation parameter interval corresponding to each sintering operation parameter a is obtained, that is the most related sintering operation parameter interval of the sintering operation parameter a is larger than B1.
Similarly, two sintering operation parameters corresponding to the end temperature are a and d respectively, at least one sintering operation parameter interval corresponding to each sintering operation parameter is obtained, specifically, the sintering operation parameter interval of the sintering operation parameter a is a4, a5 and a6, the related sequence is that a4 is larger than a5 and larger than a6, the sintering operation parameter interval of the sintering operation parameter d is d1 and d2, the related sequence is that d1 is larger than d2, and then the most relevant sintering operation parameter interval corresponding to each sintering operation parameter is obtained, namely, the sintering operation parameter interval a4 and the sintering operation parameter interval d1 are obtained for the end temperature.
Then, for the fourth preset number of 1, the preset rule is to make the most relevant sintering operation parameter intervals of the same sintering operation parameter of all the abnormal parameters of the sintering state quality correspond to each other, and the sintering operation parameter intervals of different types do not need to be intersected, that is, the sintering operation parameter of the same type of the main negative pressure and the end point temperature is a, the most relevant operation parameter interval a1 of the sintering operation parameter a of the main negative pressure and the most relevant operation parameter interval a4 of the end point temperature are intersected, for example, a1 is [ 780, 800 ], a4 is [ 770, 790 ], then the intersection is a [ 780, 790 ] and the sintering operation parameter intervals of different types do not need to be intersected, so that the target sintering operation parameter interval of the main negative pressure is a [ 780 ], the sintering operation parameter interval b1, the sintering operation parameter interval c1, and the target sintering operation parameter interval a1 of the end point temperature are obtained.

And on the basis of real-time data, the method carries out quick analysis by a big data technology, has strong instantaneity, strong generalization capability of the production line and accurate analysis result, is convenient for assisting on-site operators to quickly make decisions, further improves the overall stability of the sintering production line, and reduces the sintering production cost.
