Examples
Referring to fig. 1, an application scenario of the chromatograph cluster control method provided in this embodiment is schematically illustrated.
As shown in fig. 1, the chromatograph cluster control method provided by the present invention is applied to a chromatograph cluster control device 200 of a chromatograph cluster system 100, where the chromatograph cluster system 100 includes the chromatograph cluster control device 200 and a plurality of online chromatographs 300, and the chromatograph cluster control device 200 implements online control of the plurality of online chromatographs 300, and the chromatograph cluster system 100 is provided with a communication module, and the chromatograph cluster control device 200 receives and sends information to the outside through the communication module. The sample to be analyzed is transmitted to the chromatograph cluster system 100 through an acquisition device or a transmission device externally connected to the chromatograph cluster system 100, the chromatograph cluster control device 200 controls the corresponding online chromatograph 300 to perform the chromatographic analysis on the sample to be analyzed, and the communication module transmits the analysis result and the information recorded in the analysis process to the outside.
On the basis, as shown in fig. 2, the chromatograph cluster control method provided by the present invention is applied to the chromatograph cluster system 100, and the method includes:
and S101, receiving a sample to be analyzed, and acquiring the parameter index information. The sample to be analyzed is provided with parameter index information for marking the target analysis state of the sample to be analyzed, and the parameter index information comprises target temperature, target pressure and target carrier gas type.
The corresponding mark carried by the sample to be analyzed comprises parameter index information of the target analysis state of the sample, and is used for indicating the chromatographic analysis of the sample under what environment.
Step S102, detecting the working state of the equipment of the online chromatograph in the chromatograph cluster system, and acquiring the equipment state information of the online chromatograph; the equipment state information comprises chromatographic column temperature information, internal pressure information, carrier gas type information and equipment working stage information.
The working states of a plurality of online chromatographs included in the chromatograph cluster system are mutually independent, and when a sample to be analyzed needs to be subjected to chromatographic analysis, the working states of the devices of the online chromatographs are detected for subsequent distribution of the most appropriate online chromatographs. For the chromatograph, the temperature and the internal pressure are two parameters which have the greatest influence on the operation of the equipment, so that the numerical values of the two parameters are emphasized to be detected. On the other hand, whether the carrier gas type is appropriate or not also affects the waiting time of sample analysis to a certain extent, and if the carrier gas type is switched, a certain time is needed. The detection of the working phase of the equipment can directly judge whether the equipment is idle or not, or judge the time required by the equipment to finish the current analysis process.
And step S103, comparing the equipment state information of the online chromatograph with the parameter index information, and determining the online chromatograph with the highest priority. The specific determination method comprises the following steps:
judging whether an online chromatograph in an idle state exists or not; if yes, determining any one online chromatograph in the idle state to have the highest priority; and if not, comparing the parameter index information with the equipment state information of the online chromatograph in sequence, and selecting the online chromatograph with the highest similarity as the online chromatograph with the highest priority.
And when the idle online chromatograph exists, the idle online chromatograph is directly arranged to analyze and process the sample to be analyzed. When all the devices are in the non-idle state, the parameter index information of the sample to be analyzed and the device state information of the online chromatograph need to be compared, and the optimal resource allocation mode is selected by comprehensively considering factors in various aspects such as waiting time, device parameter adjustment complexity and the like.
And step S104, distributing the sample to be analyzed to a sample introduction system of the online chromatograph with the highest priority.
After comprehensive consideration and comparison, an optimal distribution mode is selected, namely, an online chromatograph with the highest priority performs analysis processing on a sample to be analyzed.
The chromatograph cluster control method provided by the embodiment is applied to a chromatograph cluster system comprising a plurality of online chromatographs, when the chromatograph cluster analyzes a large batch of samples to be analyzed, the target analysis state of the samples to be analyzed is compared with the state information of each online chromatograph device in the chromatograph cluster system, the samples to be analyzed are analyzed by reasonably distributing the corresponding online chromatograph devices, the overall working efficiency of the chromatograph cluster system is improved, more samples can be analyzed in unit time, and the production cost of enterprises is effectively reduced.
As shown in fig. 3, a chromatograph cluster control method according to another embodiment of the present invention is applied to a chromatograph cluster system 100 including a plurality of online chromatographs, and includes:
step S201, receiving a sample to be analyzed, and acquiring the parameter index information. The sample to be analyzed is provided with parameter index information for marking the target analysis state of the sample to be analyzed, and the parameter index information comprises target temperature, target pressure and target carrier gas type.
Step S202, judging whether two or more samples to be analyzed are received continuously, wherein the parameter index information is completely the same, if so, executing step S221, otherwise, executing step S203.
And step S221, sequentially distributing the samples into sample introduction systems of the same online chromatograph.
When the parameter index information of a plurality of samples to be analyzed are continuously received and are completely the same, the device is convenient to directly and continuously process, so that the samples are distributed to the same online chromatograph to be sequentially processed, and when the online chromatograph processes the samples to be analyzed, various parameters in operation are not required to be adjusted midway, so that the use efficiency is improved. After step S221 is executed, other subsequent steps are not executed.
Step S203, detecting the working state of the online chromatograph in the chromatograph cluster system, and acquiring the equipment state information of the online chromatograph. The equipment state information comprises chromatographic column temperature information, internal pressure information, carrier gas type information and equipment working stage information.
And step S204, detecting whether the samples to be analyzed exist in the sample introduction system of the online chromatograph. If so, step S241 is performed, otherwise, step S205 is performed.
Step S241 is a wait for a preset wait time. Wherein the waiting time is greater than an average time for the on-line chromatograph to complete an analysis procedure. After waiting, the sampling system is detected, i.e. the step S204 is executed again.
And S205, selecting an online chromatograph without the sample to be analyzed in the sample injection system, and carrying out subsequent comparison.
When the sample to be analyzed enters the chromatograph cluster system to wait for analysis, part of the online chromatographs in the system are already allocated with other samples to be analyzed before the sample to be analyzed, and the allocated samples to be analyzed are still in a waiting analysis state and are also stored in a sample injection system of the online chromatographs. At this time, if there is no sample to be analyzed in the sample injection system with part of the on-line chromatographs in the system, these on-line chromatographs are selected for subsequent comparison.
If all the on-line chromatographs in the system already have a sample to be analyzed, even if the sample to be analyzed which has just entered is distributed, it cannot immediately enter the subsequent analyzing action. It is therefore possible to wait for a period of time, which is generally set to be greater than the average time for the on-line chromatograph to complete an analysis procedure. Therefore, after one waiting, more than one online chromatograph is necessary, and the sample to be analyzed no longer exists in the sample feeding system. At this time, an online chromatograph without a sample to be analyzed in the sample injection system is selected for subsequent comparison.
In this way, on the one hand, the time taken for the sample to be analyzed does not have an influence, and on the other hand, the allocation scheme can be further optimized.
And step S206, comparing whether the target temperature is the same as the chromatographic column temperature information. If not, go to step S261; if yes, further judgment is needed to be made whether the target temperatures of the plurality of online chromatographs are the same as the temperature information of the chromatographic columns. If there is only one, step S210 is executed; if there are more than one, further comparison is required, and step S207 is performed.
And step S261, selecting the online chromatograph with the minimum difference value between the chromatographic column temperature information and the target temperature. After the selection is completed, the number of the selected online chromatographs also needs to be judged, and if only one online chromatograph is selected, the step S210 is executed; when there are a plurality of the data, further comparison is required, and step S209 is performed.
Step S207, comparing whether the target pressure is the same as the internal pressure information. As a preferred embodiment of the present embodiment, if no, step S271 is executed. If yes, further judgment is needed to be made whether the target pressures of the plurality of online chromatographs are the same as the internal pressure information. If there is only one, step S210 is executed; if there are more than one, further comparison is required, and step S208 is performed.
Step S271, selecting an online chromatograph having the minimum difference between the target pressure and the internal pressure information. After the selection is completed, the number of the selected online chromatographs also needs to be judged, and if only one online chromatograph is selected, the step S210 is executed; when there are a plurality of the data, further comparison is required, and step S209 is performed.
Step S208, comparing whether the target carrier gas type is the same as the carrier gas type information. If not, go to step S209; if yes, further judgment is needed to be made whether the target carrier gas types of the plurality of online chromatographs are the same as the carrier gas type information. If there is only one, step S210 is executed; when there are a plurality of the data, further comparison is required, and step S209 is performed.
And step S209, further judging the working stage information of the equipment, and determining the online chromatograph which completes the current analysis process firstly according to the working stage information of the equipment.
In step S210, the online chromatograph is determined to have the highest priority.
And judging the weight pair to be the highest temperature, the next pressure and the next carrier gas type in the target temperature, the target pressure and the target carrier gas type which are included in the parameter index information, so that the weight sequence of the influence of the parameters on the chromatographic quality to be analyzed is reflected.
Therefore, when comparing the equipment state information with the parameter index information, the target temperature and the chromatographic column temperature information are compared firstly, and the comparison result can be divided into three cases:
(1) there are multiple online chromatographs with column temperature information that is the same as the target temperature information, at which point further comparisons of other parameters are needed. (2) The online chromatograph with the same chromatographic column temperature information and target temperature information exists, and the highest priority of the online chromatograph is directly determined without further comparison of other parameters. (3) And selecting the online chromatograph with the minimum difference value between the chromatographic column temperature information and the target temperature at the moment.
For case (1), sorted by weight, the target pressure is compared with the internal pressure information. For case (2), the online chromatograph with the highest priority has already been determined. For the case (3), a plurality of online chromatographs which simultaneously satisfy the conditions still exist, and other parameters are not compared at this time, because the deviation of the other two parameters is considered under the condition of different temperatures, the influence on the waiting time is smaller than the influence on the working stage of the equipment, and therefore the information on the working stage of the equipment is directly judged.
The case of comparing the target pressure with the internal pressure information is similar to the last comparison, and the comparison result can be divided into three cases:
A. there are multiple on-line chromatographs with the same target pressure as the internal pressure information, and further comparison of other parameters is needed. B. An online chromatograph with the same target pressure and internal pressure information exists, and the highest priority of the online chromatograph is directly determined without further comparison of other parameters. C. And (4) the online chromatograph with the same target pressure and internal pressure information does not exist, and the online chromatograph with the minimum difference value between the target pressure and the internal pressure information is selected.
For case a, the target carrier gas type is compared with the carrier gas type information, ordered by weight. For case B, the online chromatograph with the highest priority has already been determined. In case C, a plurality of online chromatographs that simultaneously satisfy the conditions may still be present, and at this time, no comparison with other parameters is performed, because under the same temperature and the different target pressure and internal pressure information, the deviation of the remaining parameter is considered, and the influence on the waiting time is smaller than the influence on the device working phase, so that the device working phase information is directly determined.
The case of comparing the type of the target carrier gas with the type information of the carrier gas is similar to the comparison of the two parameters, and the comparison result can be divided into three cases:
a. and an online chromatograph with the same type of target carrier gas and carrier gas exists, and the working stage information of the equipment needs to be further judged at the moment. b. An online chromatograph with the same target carrier gas type and carrier gas type information exists, and the highest priority of the online chromatograph is directly determined without further comparison of other parameters. c. And (4) judging the working stage information of the equipment at the moment when the online chromatograph with the target carrier gas type being the same as the carrier gas type does not exist.
The method comprises the steps of judging the working stage information of the equipment, namely judging which stage of an analysis process the online chromatograph is at currently, and further estimating the approximate time for finishing the current analysis process, wherein the time is the basic time for waiting for the next sample to be analyzed, when the online chromatograph is in the working stage closer to the front, the basic time is longer, and when the online chromatograph is in the working stage closer to the rear, the basic time is shorter.
