Referring to fig. 3, which is a flowchart illustrating an online control method for a chromatograph according to some embodiments of the present application, the method is applied to a chromatograph server 200, and may specifically include the following steps S-step S, and some alternative embodiments will be described.
The chromatograph online control method provided by the embodiment is mainly applied to providing an online spectrum determination system, and mainly has the advantages that based on the existing internet system, the acquisition of multiple groups of people on the chromatogram and the determination of substances are realized by building a set of system and a method.
The existing chromatograph is mainly used for qualitatively detecting specific mixtures or substances in a laboratory, and most target personnel are specific scientific researchers and production related personnel. However, since the chromatograph is a special product, and it is impossible to provide a wider spectrum for general scientific research interest or under the scene where a small number of chromatographs exist but have strong experimental needs, a system and a method are needed to meet the needs of a large number of people to use the chromatograph under the condition that a small number of chromatographs exist based on the internet technology.
Therefore, based on the technical background, the present embodiment provides an online chromatograph control method, which can satisfy the use of the chromatograph by a large number of people based on the internet.
The internet can be a world wide web or a local area network based on a regional architecture, but the implementation logics are the same, the information of the to-be-detected article and the sample provider is determined for acquiring corresponding personnel, the chromatograph is used for carrying out experiments, the qualification of the article is realized based on the data processing, the information is fed back to the corresponding personnel, and the whole process is completed.
Because the detection process based on the method is a continuous process, the variety of samples is complicated, and a certain error is generated for a chromatograph, the detection result, namely a chromatographic peak, needs to be corrected and removed to a certain extent in order to ensure the accuracy of the detection result. Therefore, in the online chromatograph control method provided in this embodiment, data denoising processing is also required.
Therefore, the online chromatograph control method provided by the embodiment mainly includes four specific steps:
determining a sample providing user corresponding to the sample, and establishing a connection;
pretreating a sample, determining the type range of the sample, and adjusting the detection condition;
obtaining a chromatographic peak based on a chromatograph, and removing noise and rectifying the chromatographic peak;
and comparing the samples aiming at the obtained chromatographic peaks, determining the samples, and sending result information to corresponding users.
The present embodiment is described in detail with respect to the above process:
step S1, acquiring the first tag sent by the identification terminal.
In this embodiment, the identification terminal is used for identifying information in the sample, wherein the information mainly comprises user information and sample information. The method is characterized in that how information is constructed can be realized through software, and a user inputs the information through the software, wherein the information comprises the information of the user, namely user ID, namely key personnel name, mailbox and geographical geology; the sample information includes relevant data of the sample, and in this embodiment, the data of the sample does not need to be provided completely and comprehensively, and only needs to be provided with rough categories for use purposes. For the determination of the category, a questionnaire may be provided in software or a computer program, and the sample may be determined to approximate the range by a specific question. For example, when a user performs qualitative processing on a certain composition and samples information is reported, software can provide property investigation, such as liquid state, viscous state or solid state, for the sample, and further narrow the range for more accurate investigation, such as the property of the product in a certain use scene, the property of the product in a certain temperature range, and the like. It is also possible to set questions, such as the usage scenario of the sample, for what specific treatments and effects to achieve based on what reactions under what conditions. Specific questions may also be set, such as where the user determines the general classification of the sample, e.g., the sample is an ester or aldehyde, and may also be filled in with this information.
The above information is mainly intended to realize rough judgment of a sample.
After the information is filled, the user obtains a unique identification code corresponding to the sample, the code can be a bar code or a two-dimensional code, and the code is downloaded and printed to be sent to a specific place along with the sample for detection processing.
Based on the scheme, the embodiment also provides a preferable scheme that the online chromatograph can be a plurality of chromatographs in a plurality of regions, and the nearby detection location can be recommended according to the specific geographic position information to realize the nearby detection.
For the unique identification code, the detection device, i.e. the chromatograph, first identifies the unique identification code through the identification terminal, which in this embodiment may be a code scanning gun or other code scanning devices, and retrieves the related information, i.e. the first tag.
Step S2, associating the first label with the constructed user list and retrieving the first information.
And aiming at all the acquired information, the association is realized by calling a user list which is generated and stored during information filling, a sample provider and a detection user are determined, the information is updated in real time at the user terminal, and the updated information is sent to the user terminal. The update message includes the completed sample listing, the pending test, etc.
The first information is sample information, including questionnaire-related information and information on filling out of the sample by the user.
And step S3, correlating the first information with the standard sample database to determine a temperature adjusting command, and sending the temperature adjusting command to the chromatograph.
In this embodiment, a standard sample database is constructed before the sample identification, the standard sample database is classified into a plurality of categories by identifying the large classes of chemical substances, and the temperature intervals are classified according to the large classes, and in the process of qualitative processing of a substance by a chromatograph, different temperature thresholds are required to identify the substance because the precipitation temperature intervals of the chemical composition are different. In a conventional use scene, detection processing is mostly performed on products with the same type or similar temperature intervals. Therefore, no special temperature adjustment is required, but the chromatograph control method provided by the present embodiment is mainly for determination of a wide range of substances. Therefore, the temperature interval of the sample to be detected needs to be determined every time the sample is detected, so that the detection method can be determined more accurately to ensure the accuracy of qualitative processing.
Step S31, comparing the feature value based on the first information with the feature values of the plurality of standard samples.
In terms of how to regulate and control the temperature, in the method provided in this embodiment, a characteristic value of the first information is first determined, and in this embodiment, the characteristic value of the first information is a range classification of the sample, such as aldehydes, esters, acids, and the like; if the core component of the sample is determined, the core component is also a characteristic value.
And comparing the characteristic value of the sample with the corresponding characteristic value of the stored standard sample, wherein the comparison result is not a unique result and is a plurality of results.
In step S32, a target standard sample is determined based on a confidence algorithm.
For multiple alignment results, a target standard sample is inferred based on a confidence algorithm.
And step S33, acquiring the temperature of the target standard sample.
In step S34, a target temperature is determined based on the target standard sample temperature.
Based on the estimated target sample and the corresponding temperature in the database, a target temperature is determined, i.e. the temperature threshold to be controlled.
The column temperature of the constant temperature column is controlled according to the target temperature, the temperature control in this embodiment may be control logic based on a fuzzy algorithm, the control logic is the prior art, the description is not emphasized in this embodiment, and the target is to control the temperature within a threshold range, so as to achieve the accuracy of detection on the sample.
In step S4, chromatographic data is acquired.
Based on the working principle and mechanism of the chromatograph, preliminary chromatographic data is obtained.
And step S5, acquiring at least one group of standard chromatographic matching data sent by the inquiry terminal.
Since the chromatograph provided in this embodiment operates continuously and causes inaccuracy of data, a certain processing is required for the generated chromatographic data. However, the process of the chromatogram data is not a blank process, and the chromatogram data needs to be corrected based on standard chromatogram data as a reference. In the online chromatograph control method provided in this embodiment, the query terminal is provided, and the query terminal is provided with the standard chromatographic data, and the target data is determined by comparing the standard chromatographic data with the query terminal.
And step S6, performing characteristic chromatographic data identification on the standard chromatographic matching data to obtain target chromatographic data.
When the target chromatographic data is identified, conventionally, a confidence interval is set, the chromatographic data obtained by detection is matched with standard chromatographic data, and a comparison result in the confidence interval can determine a specific chromatographic data correction result. However, since the chromatograph provided in the present embodiment is continuously operated, there is a possibility that an error interval is large, and in this case, data needs to be processed deeply. Therefore, the present embodiment provides a method for comparing and correcting chromatographic data, which specifically includes the following steps:
step S61, determining a chromatographic peak.
In the online chromatograph control method provided by this embodiment, for determining a chromatographic peak, first, a time window with a preset size is sequentially slid from an acquired chromatographic curve starting point to perform detection processing on the chromatographic peak until processing of original spectrogram data is completed, all chromatographic peaks in the curve are detected, and a detection result is generated based on the detected chromatographic peaks;
step S611, comparing the slope of each point on the chromatographic curve with a threshold value, and determining a reference point of a chromatographic peak based on the comparison result;
in a chromatograph, a plurality of chromatographic peaks generally exist for a certain complete spectrogram data, in other words, each chromatographic peak is detected sequentially by sliding a time window during the detection process. Therefore, there are a plurality of chromatographic peaks, and a plurality of chromatographic peaks have a plurality of points on the base of the chromatogram.
In this embodiment, in order to compare chromatographic peaks, the slopes of the points on the chromatographic curve need to be compared with a threshold, and a reference point of the chromatographic peak is determined based on the comparison result, where the reference point includes a peak start point reference point, a temporary peak top point reference point, and a peak end point reference point, and the threshold is determined based on a calculation analysis of an idle output signal of a chromatographic instrument that generates raw spectrogram data.
Different from the prior art, in the process of detection based on the slope, the threshold is not manually set, but is determined based on calculation and analysis of a no-load output signal of a chromatographic instrument for generating original spectrogram data.
And step S612, based on the position of the chromatographic peak represented by the reference point on the chromatographic curve, performing pattern recognition detection on the chromatographic curve near the position by taking a Gaussian wave as a matching wave, and taking the peak top in the recognition detection result as a peak top correction point.
Step S613, correcting the temporary peak-top reference point according to the peak-top correction point, and using the corrected point as a peak-top reference point;
specifically, in this step, by comparing the vertical coordinate values of the peak-top correction point and the temporary peak-top reference point, a point having a larger vertical coordinate value is determined as the peak-top reference point.
And step S614, determining the chromatographic peak represented by the peak starting point reference point, the peak end point reference point and the peak top point reference point as the detected chromatographic peak.
Step S62, determining the slope of the starting point, the slope of the peak point and the slope of the end point of the chromatographic peak;
step S63, determining the slope of the starting point, the slope of the peak point and the slope of the end point of each chromatographic peak in the standard chromatographic matching data;
step S64, comparing each slope of the chromatographic peak with each slope of the standard chromatographic matching data to obtain a matching degree;
and step S65, determining a target chromatographic peak based on the obtained matching degree.
And step S7, sending the identified target chromatographic data to the inquiry terminal.
And step S8, selecting the sample information corresponding to the target chromatographic data for matching, and sending the sample information to the user terminal.
And storing the finally determined analysis result of the sample, and synchronizing the stored information to the user terminal to complete the overall processing.
The embodiment of the present application further provides a control device based on an online chromatograph, configured to perform the above method, where the chromatograph control device is applied to a chromatograph server, and the control device includes:
the acquisition module is used for acquiring the first label sent by the identification terminal, acquiring chromatographic data and acquiring at least one group of standard chromatographic matching data sent by the query terminal. In the present embodiment, the obtaining module is configured to execute the step S2, the step S4, and the step S5.
And the association module is used for associating the first label with the constructed user list and calling first information, and is also used for associating the first information with the standard sample database to determine a temperature regulation command. In the present embodiment, the association module is configured to execute the step S2 and the step S3.
