Referring to fig. 3, fig. 3 is a flowchart illustrating a method for detecting a fault based on a chromatograph applied to the electronic device 100 according to some embodiments of the present disclosure. The method can include the following steps S1-S6, each of which will be described in detail below.
In step S1, the test chromatogram data and the auxiliary determination information corresponding to the test chromatogram data are acquired.
In an embodiment of the present application, the auxiliary judgment information includes a test execution time of the test chromatogram data and integrated data of the first chromatograph that generates the test chromatogram data. The test chromatographic data is data, such as a chromatographic profile, generated by chromatographic separation of a sample by chromatograph 200. The test execution time is a time point at which a chromatographic separation test is started, and the integrated data represents factors affecting chromatographic data of the chromatograph in the chromatographic test, such as a stationary phase of the chromatograph, an ambient temperature around the chromatograph, a time interval between a current execution time of the chromatograph and a standard time, a flow rate of the mobile phase, and the like.
In the embodiment of the application, the test chromatographic data sent by the first chromatograph and the auxiliary judgment information corresponding to the test chromatographic data can be directly obtained. In other embodiments, each chromatograph corresponds to an independent number, and when data is acquired, the test chromatogram data sent by the first chromatograph, the test execution time of the test chromatogram data, and the number of the first chromatograph may also be acquired, and then the comprehensive data of the first chromatograph is determined according to the number of the first chromatograph, so as to obtain the auxiliary judgment information of the test chromatogram data.
Step S2, determining the basic matching degree of the test chromatogram data and each contrast chromatogram data in the preset contrast chromatogram database one by one, and determining the overall matching degree of the test chromatogram data and each contrast chromatogram data through the auxiliary determination information and the contrast auxiliary determination information of each contrast chromatogram data.
The main components of the chromatographic data are chromatographic peaks, including the number, the occurrence time, the peak area, the peak height, the peak width, the symmetry and the like of the chromatographic peaks, so that the contrast chromatographic data closest to the test chromatographic data can be obtained by comparing the indexes of the test chromatographic data and the contrast chromatographic data, and further the basic matching degree can be obtained. The overall matching degree is the matching degree of the test chromatographic data and the comparison chromatographic data at the chromatographic level and the test environment level, namely not only the similarity on the chromatographic spectrum is considered, but also the influence brought by the test environment is considered. And analyzing and judging the overall matching degree through the auxiliary judgment information and the comparison auxiliary judgment information of each comparison chromatographic data. Specifically, in the embodiment of the present application, the process of determining the overall matching degree may include the following steps:
step S21, for each of the comparison chromatogram data, the test environment information of the test chromatogram data and the comparison chromatogram data is determined by the comparison auxiliary determination information of the auxiliary determination information and the comparison chromatogram data.
In the embodiment of the present application, the test environment information is used to characterize the correlation between the test execution time and the chromatograph execution environment of the test chromatogram data and the comparison chromatogram data. For example, the test environment information may be a stationary phase of each of the first and second chromatographs generating the comparative chromatographic data, a time interval of test execution time of the test and comparative chromatographic data, a first flow rate of the mobile phase in the test chromatographic data, a second flow rate of the mobile phase in the comparative chromatographic data, and a failure unification probability between the first and second chromatographs. The stationary phase of the first and second spectrometers is different and directly affects the shape, e.g., the retention time, of the chromatographic data generated. If the time interval between the test execution time of the test chromatographic data and the test execution time of the comparison chromatographic data is too long, the shapes of the chromatographic column are likely to generate larger fluctuation and difference due to the problems of aging of the chromatographic column, more pollution caused by the middle test of the chromatographic column and the like, the flow rate of the mobile phase affects the performance of the time dimension of the chromatographic column, the unified fault probability is a probability for representing the consistency between the sample fault type in the test chromatographic data and the sample fault type in the comparison chromatographic data, and can be obtained through a large number of test analyses, in the large number of tests, the samples in different periods are tested at different time intervals to obtain corresponding faults corresponding to the samples in corresponding periods, so as to speculate what faults can occur to the equipment after what time interval, for example, the last test and the current test are 1 month, if it is a failure, it is likely what failure will occur. Of course, the failure prediction is not accurate in one dimension of the time interval, and therefore, it is preferable that it is used as a reference index to be analyzed in combination with the method of the embodiment of the present application.
Step S22, for each of the comparison chromatogram data, determining the chromatogram data information of the test chromatogram data and the comparison chromatogram data from the chromatogram data of the test chromatogram data and the chromatogram data of the comparison chromatogram data.
The atlas data information includes at least one of: the basic matching degree of the test chromatographic data and the comparison chromatographic data, the preset map characteristic information of the test chromatographic data and the preset map characteristic information of the comparison chromatographic data, wherein the preset map characteristic information at least comprises the number of chromatographic peaks and the chromatographic peak area corresponding to each chromatographic peak.
And step S23, determining the integral matching degree of the test chromatographic data and the comparison chromatographic data through the test environment information and the map data information of the test chromatographic data and the comparison chromatographic data for each comparison chromatographic data.
The test environment information includes the similarity of the test chromatogram data and the comparison chromatogram data in the test environment, such as whether the same stationary phase is adopted, whether the test conditions of the chromatographic column are close during the test, whether the probability of the same fault is existed, and the like. And determining the integral matching degree of the test chromatographic data and the comparative chromatographic data, namely the matching degree of the test chromatographic data and the comparative chromatographic data on the chromatographic level and the experimental environmental level by combining the test environmental information and the chromatographic data information of the test chromatographic data and the comparative chromatographic data.
Through the steps, the overall matching degree of the test chromatographic data and each comparison chromatographic data is obtained so as to carry out the subsequent analysis step. As another embodiment, in the comparison chromatographic database, a plurality of chromatographic data queues may be included, each chromatographic data queue including a plurality of comparison chromatographic data, and step S2 may include:
at step S21', for each chromatographic data queue, a basic matching degree of the test chromatographic data with the reference chromatographic data of the chromatographic data queue is determined as the basic matching degree of the test chromatographic data with each comparison chromatographic data in the chromatographic data queue.
In this embodiment, each chromatographic data queue includes a plurality of comparison chromatographic data, and the failure types pointed to by the comparison chromatographic data in the same chromatographic data queue are consistent, that is, the basic matching degree and the overall matching degree between the comparison chromatographic data in the same chromatographic data queue are close, and the test chromatographic data can be matched with one of the chromatographic data queues and can also be matched with other comparison chromatographic data in the chromatographic data queue. The reference chromatography data represents the most representative comparative chromatography data in the chromatography data cohort.
And step S22', for the chromatographic data queue, determining the overall matching degree of the test chromatographic data and the reference chromatographic data of the chromatographic data queue as the overall matching degree of the test chromatographic data and each contrast chromatographic data of the chromatographic data queue according to the auxiliary judgment information and the contrast auxiliary judgment information of the reference chromatographic data of the chromatographic data queue.
Compared with the above contents, in the step S22', when the overall matching degree is determined, the comparison auxiliary judgment information of the reference chromatographic data is directly used as an analysis basis, so that comparison with each comparison chromatographic data in the chromatographic data queue is avoided, data calculation and memory occupation are reduced, and calculation efficiency is improved.
Before determining the basic matching degree of the test chromatographic data and each contrast chromatographic data in the contrast chromatographic database one by one, in order to avoid useless analysis, the method may further include:
and determining data qualification indexes of the chromatographic data of the test, wherein the data qualification indexes at least comprise that the baseline does not drift, no front peak and peak tailing occur, no peak occurs and no peak becomes small. Once data such as baseline drift, leading edge peaks, etc. are presented, problems during sample testing, such as mishandling, column aging, and gas leakage, are indicated. And if the data qualification index meets the preset requirement, executing a step of determining the basic matching degree of the test chromatographic data and each contrast chromatographic data in the contrast chromatographic database.
Step S3, determining target contrast chromatogram data corresponding to the test chromatogram data based on the basic matching degree and the overall matching degree of the test chromatogram data and each of the contrast chromatogram data in the contrast chromatogram database.
As described above, the basic matching degree and the overall matching degree can be compared with the contrast chromatogram data from multiple dimensions to determine the best matching target contrast chromatogram data, and the specific process may refer to the following steps:
step S31, for each piece of comparison chromatogram data, if the basic matching degree of the test chromatogram data and the comparison chromatogram data is greater than the first preset matching degree, determining the comparison chromatogram data as the target comparison chromatogram data corresponding to the test chromatogram data.
The basic matching degree is directly compared from the spectrum level of the chromatographic data, such as the number, the occurrence time, the maintenance time, the peak area, the peak height, the peak width, the symmetry and the like of the chromatographic data, so that the common degree of the chromatographic data and the contrast chromatographic data can be visually and accurately reflected, if the basic matching degree of the test chromatographic data and the contrast chromatographic data is greater than the first preset matching degree, the matching degree of the test chromatographic data and the contrast chromatographic data is high, the test chromatographic data and the contrast chromatographic data can be directly considered to belong to the same fault type, and other factors do not need to be considered.
And step S32, if the basic matching degree of the test chromatographic data and the comparison chromatographic data is less than a second preset matching degree, determining the next comparison chromatographic data one by one, wherein the second preset matching degree is less than the first preset matching degree.
If the basic matching degree of the test chromatographic data and the comparison chromatographic data is smaller than the second preset matching degree, the matching degree of the test chromatographic data and the comparison chromatographic data is low, the test chromatographic data and the comparison chromatographic data can be directly considered not to belong to the test chromatographic data of the same fault type, other factors do not need to be considered, and then the next pair of colorimetric data is traversed.
And step S33, if the basic matching degree of the test chromatographic data and the contrast chromatographic data is smaller than the first preset matching degree but larger than the second preset matching degree, determining the contrast chromatographic data as the target contrast chromatographic data corresponding to the test chromatographic data when the overall matching degree of the test chromatographic data and the contrast chromatographic data is larger than the third preset matching degree.
If the basic matching degree of the test chromatographic data and the comparison chromatographic data is smaller than the first preset matching degree but larger than the second preset matching degree, the conclusion cannot be directly drawn, and other factors are needed for auxiliary judgment, for example, the overall matching degree is obtained by combining the test environment, when the overall matching degree of the test chromatographic data and the comparison chromatographic data is larger than the third preset matching degree, the comparison chromatographic data can be further proved to be the target comparison chromatographic data corresponding to the test chromatographic data, if the overall matching degree is smaller than the third preset matching degree, the comparison chromatographic data is not the target comparison chromatographic data corresponding to the test chromatographic data, and at this time, the next pair of colorimetric data is traversed.

Step S5, storing the test chromatographic data in the comparison chromatographic database, and updating the test chromatographic data into the comparison chromatographic data.
Since the test chromatographic data can be matched with one or more of the comparison chromatographic data in the comparison chromatographic database to find the target comparison chromatographic data, the test chromatographic data can be used as the comparison chromatographic data of the next test chromatographic data needing fault analysis, and therefore, the test chromatographic data is stored in the comparison chromatographic database and is updated into paired chromatographic data.
In step S6, mapping information of the fault types corresponding to the test chromatogram data and the stored target contrast chromatogram data is generated in the contrast chromatogram database.
