Description

Technical Field

[0001] The present invention belongs to the technical field of microbial laboratory equipment management, and specifically relates to a method and system for ultraviolet management in a microbial laboratory. Background Art

[0002] In the daily operation of a microbial laboratory, ultraviolet lamps play a crucial role. The ultraviolet rays they generate can effectively kill microorganisms in the air and on the surface of objects, providing necessary disinfection guarantee for the experimental environment, thereby ensuring the accuracy and reliability of experimental results. However, as a consumable, the service life of ultraviolet lamps is limited. As the usage time increases, the disinfection effect will gradually decline, so they need to be replaced regularly.

[0003] In the prior art, only the cumulative usage time of a single lamp is concerned, while ignoring the degree of association between the historical service life ratio and the historical usage frequency ratio among lamps of the same batch, which cannot accurately reflect the impact of historical usage frequency on historical service life, resulting in a lack of sufficient data support for predicting the remaining service life of the lamp, and thus making it difficult to accurately grasp the timing of lamp replacement;

[0004] Secondly, in the existing lamp replacement strategy, usually only the usage duration or intensity threshold is used as the replacement basis, without considering the accelerated loss of life caused by the difference in usage frequency of lamps in different areas, lacking a lamp load balancing strategy based on usage frequency, and unable to reduce the pressure in high-frequency areas by interchanging lamps, resulting in uneven distribution of the overall lamp life in the laboratory.

[0005] Therefore, the present invention provides a method and system for ultraviolet management in a microbial laboratory. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: In a first aspect, a method for ultraviolet management in a microbial laboratory includes: During the historical usage period, conduct a correlation analysis on the historical service life ratio and the historical usage frequency ratio of ultraviolet lamps to evaluate whether the correlation is close; If the correlation is close, obtain the life correlation coefficient, predict the current remaining life of the ultraviolet lamps in the current period, and construct a management sequence to be replaced; Conduct an irradiation intensity analysis on the ultraviolet lamps in the management sequence to be replaced, evaluate the uniform stability of the irradiation intensity, and screen out unstable uniform areas and stable uniform areas; Perform irradiation frequency analysis on the unstable uniform area and the stable uniform area, screen out the areas to be interchanged and the areas to be swapped, and interchange the ultraviolet lamps in the areas to be interchanged and the areas to be swapped.

[0008] As a further solution of the present invention: Evaluate whether the association is close, and the process is as follows: Obtain the ratio of the historical usage time of each ultraviolet lamp to the total cycle duration of the historical usage cycle as the historical service life ratio, obtain the ratio of the historical usage times of each ultraviolet lamp to the total historical usage times of all ultraviolet lamps as the historical usage frequency ratio, construct an association analysis change curve, and combine adjacent coordinate points to obtain adjacent analysis groups. Output the association analysis value through the Manhattan distance calculation formula. If it is less than or equal to the association analysis threshold, generate an association close signal.

[0009] As a further solution of the present invention: Obtain the life correlation coefficient, and the process of constructing the loss life prediction model is as follows: Based on the association close signal, calculate the average value of the adjacent change slopes corresponding to all adjacent analysis groups to obtain the life correlation coefficient; Based on the life correlation coefficient, construct a loss life prediction model, and the corresponding equation is: , where is the life correlation coefficient, is a constant.

[0010] As a further solution of the present invention: Predict the current remaining life and construct a replacement management sequence, and the process is as follows: Equally divide the current cycle into several current time periods, obtain the ratio of the usage times of any ultraviolet lamp in each current time period to the duration of the current time period to obtain the unit usage frequency, and sum them to obtain the current usage frequency; Input the current usage frequency into the loss life prediction model to obtain the current loss life, perform a difference process with the preset replacement loss life, and take the absolute value to obtain the current remaining life; Arrange all ultraviolet lamps in descending order according to the corresponding current remaining life to obtain a replacement management sequence.

[0011] As a further solution of the present invention: Perform irradiation intensity analysis on the ultraviolet lamps in the replacement management sequence to obtain an intensity stability value, and the process is as follows: Set an irradiation monitoring cycle and divide it into several irradiation monitoring nodes. Obtain the irradiation intensity in the irradiation area at each irradiation monitoring node, construct an irradiation intensity change curve, and draw a calibration intensity line intersecting the irradiation intensity change curve to obtain the intersection coordinate points; Extract the local irradiation intensity change curves between adjacent intersection coordinate points respectively as analysis sub-curves, and use the adjacent intersection coordinate points as the sub-curve start coordinate and sub-curve end coordinate of the analysis sub-curve respectively. Combine with the center point coordinate of the analysis sub-curve and calculate by the three-point coordinate curvature calculation method to obtain the sub-curve curvature. Statistically analyze the sub-curve curvatures corresponding to all analysis sub-curves, and input the sub-curve curvatures corresponding to adjacent analysis sub-curves into the Manhattan distance formula, and output to obtain the intensity stability value.

[0012] As a further solution of the present invention: perform irradiation intensity analysis on the ultraviolet lamps in the management sequence to be replaced to obtain the intensity uniformity value, and the process is as follows: In the management sequence to be replaced, obtain the irradiation areas corresponding to adjacent ultraviolet lamps, and respectively obtain the irradiation intensities corresponding to the irradiation areas, perform difference processing, and take the absolute value to obtain the adjacent intensity difference. Perform standard deviation calculation on the adjacent intensity differences, and output to obtain the intensity uniformity value.

[0013] As a further solution of the present invention: the screening process of evaluating the uniform stability of the irradiation intensity, the non-stable uniform area and the stable uniform area is as follows: Sum the intensity uniformity value and the intensity stability value, and output to obtain the uniform stability value; If the uniform stability value is less than the uniform stability threshold, it is a non-stable uniform area; If the uniform stability value is greater than or equal to the uniform stability threshold, it is a stable uniform area.

[0014] As a further solution of the present invention: the screening process of the area to be interchanged is as follows: Based on any stable uniform area, obtain the current usage frequency of the corresponding ultraviolet lamp in the current cycle, and compare it with the preset usage frequency. If the current usage frequency is less than or equal to the preset usage frequency, it is a low-dependency lamp tube, and mark the corresponding irradiation area as the area to be interchanged.

[0015] As a further solution of the present invention: interchange the ultraviolet lamps in the area to be interchanged and the area to be interchanged, and the process is as follows: Based on the intensity uniformity value, perform size comparison, and sort all low-dependency lamp tubes and the ultraviolet lamp tubes corresponding to the non-stable uniform areas from large to small respectively to obtain the sequence to be interchanged and the sequence to be interchanged. Extract the microbial experiment area corresponding to the non-stable uniform area as the area to be interchanged, and subtract the intensity uniformity values of adjacent stable uniform areas and take the absolute value to obtain the stable uniform intensity difference; Extract the maximum stable uniform intensity difference and the minimum stable uniform intensity difference to form a stable uniform intensity difference interval. Arbitrarily obtain the intensity uniformity value of the low-dependency lamp tubes within the sequence to be interchanged, and calculate the difference with the intensity uniformity value corresponding to the adjacent ultraviolet lamp tubes of the ultraviolet lamp tubes within the sequence to be interchanged in the microbial experiment area, and output the difference to be replaced; If the difference to be replaced exists within the stable uniform intensity difference range, perform an interchange operation on the ultraviolet lamp tubes.

[0016] In a second aspect, an ultraviolet management system for a microbial laboratory includes: Correlation analysis module: During the historical usage period, perform correlation analysis on the historical service life ratio and historical usage frequency ratio of each ultraviolet lamp tube in the same batch of ultraviolet lamp tubes to evaluate whether the correlation is close; Lifetime prediction module: If it is close, obtain the lifetime correlation coefficient, predict the current remaining lifetime of the ultraviolet lamp tubes in the microbial laboratory during the current period, and construct a management sequence to be replaced; Intensity monitoring module: Analyze the irradiation intensity of the ultraviolet lamp tubes within the management sequence to be replaced, evaluate the uniform stability of the irradiation intensity, and screen out non-stable uniform areas and stable uniform areas; Strategy interchange module: Analyze the irradiation frequency of the non-stable uniform area and the stable uniform area, screen out the area to be interchanged and the area to be interchanged with, and interchange the ultraviolet lamp tubes within the area to be interchanged and the area to be interchanged with.

[0017] The beneficial effects of the present invention are as follows: 1. During the historical usage period of the present invention, the historical service life ratio and historical usage frequency ratio of each ultraviolet lamp tube in the same batch of ultraviolet lamp tubes are analyzed for the degree of correlation, and a correlation analysis value is obtained. Therefore, according to the correlation analysis value, it not only reflects that the historical service life ratio and historical usage frequency ratio of each ultraviolet lamp tube in the same batch of ultraviolet lamp tubes are relatively closely related, but also indirectly reflects that the historical usage frequency of the ultraviolet lamp tubes has a greater impact on the historical service life, thus providing data support for subsequent prediction of the remaining service life of the ultraviolet lamp tubes; 2. The present invention extracts the irradiation area corresponding to each ultraviolet lamp tube within the management sequence to be replaced in the microbial laboratory, and performs irradiation intensity analysis, screening out non-stable uniform areas and stable uniform areas. Therefore, it not only reflects the influence of the ultraviolet lamp tube life on the stability and uniformity of the ultraviolet lamp irradiation intensity, but also provides technical support for actively maintaining the service life of the ultraviolet lamp tubes by identifying abnormal areas in advance. Analyze the irradiation frequency of the non-stable uniform area and the stable uniform area, screen out the area to be interchanged and the area to be interchanged with, and perform an interchange. Therefore, it not only identifies the excessive loss of the ultraviolet lamp tube life caused by high-frequency use, but also interchanges and introduces low-frequency lamp tubes to share the load of high-dependency areas, reduces the usage frequency of the original high-dependency lamp tubes, delays their performance decay, and reduces the replacement frequency.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Figure 1 is a flowchart of the steps of a method for ultraviolet management in a microbiology laboratory according to the present invention; Figure 2 is a schematic diagram of a system for ultraviolet management in a microbiology laboratory according to the present invention. Detailed Embodiments

[0020] In order to make the technical means, creative features, achieved objectives and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figure 1 shown, for a method for ultraviolet management in a microbiology laboratory according to an embodiment of the present invention, since the ultraviolet rays in the microbiology laboratory are emitted by the installed ultraviolet lamps, however, the service life or usage frequency of the same batch of ultraviolet lamps in the daily laboratory is different. If the usage time or usage frequency of the same batch of ultraviolet lamps is relatively long, it will have a greater impact on the service life of the ultraviolet lamps. Eventually, the disinfection effect of the ultraviolet lamps on the microbiology laboratory will be poor when emitting ultraviolet rays subsequently. Therefore, it is necessary to replace the ultraviolet lamps in the microbiology laboratory to reduce the impact on the disinfection effect of the microbiology laboratory, including the following steps: Step 1: In the historical usage period, perform correlation analysis on the historical service life ratio and historical usage frequency ratio of each ultraviolet lamp in the same batch of ultraviolet lamps to evaluate whether the correlation is close; In a preferred embodiment, the process for obtaining the historical service life ratio of the ultraviolet lamp is as follows: In the historical usage period, record the historical usage time of each ultraviolet lamp in the same batch of ultraviolet lamps, and calculate the ratio with the total cycle duration of the historical usage period, and output the historical service life ratio; The process for obtaining the historical usage frequency ratio of the ultraviolet lamp is as follows: Count the historical usage times of each ultraviolet lamp in the historical usage period, and calculate the ratio with the total historical usage times of all ultraviolet lamps in the historical usage period, and output the historical usage frequency ratio; Taking the historical usage frequency ratio corresponding to the ultraviolet lamp as the X-axis and the historical service life ratio as the Y-axis, construct a correlation analysis change curve according to the historical service life ratio and historical usage frequency ratio corresponding to the same batch of ultraviolet lamps; On the correlation analysis change curve, combine adjacent coordinate points to obtain adjacent analysis groups; Within adjacent analysis groups, the X-axis coordinates and Y-axis coordinates of adjacent coordinate points are respectively extracted, and the adjacent change slopes are obtained through the slope calculation formula; The adjacent change slopes corresponding to multiple groups of adjacent analysis groups are input into the Manhattan distance formula, and the correlation analysis value is output ; Specifically, the Manhattan distance formula: , and the correlation analysis value is calculated , where represents the total number of adjacent analysis groups, represents the adjacent change slope corresponding to the th group of adjacent analysis groups, adjacent change slope corresponding to the th group of adjacent analysis groups; The correlation analysis value is compared with the correlation analysis threshold, and the process is as follows: If the correlation analysis value is greater than the correlation analysis threshold, it indicates that the correlation degree between the historical usage frequency and the historical service life is less tight, and a correlation non-tight signal is generated; If the correlation analysis value is less than or equal to the correlation analysis threshold, it indicates that the correlation degree between the historical usage frequency and the historical service life is relatively tight, and a correlation tight signal is generated; This embodiment is summarized as: within the historical usage period, the ratio of the historical service life and the ratio of the historical usage frequency of each ultraviolet lamp in the same batch of ultraviolet lamps are compared, and the correlation degree analysis is carried out to obtain the correlation analysis value, so that according to the correlation analysis value, it not only reflects that the correlation degree between the historical service life ratio and the historical usage frequency ratio of each ultraviolet lamp in the same batch of ultraviolet lamps is relatively tight, but also indirectly reflects that the historical usage frequency of the ultraviolet lamp has a greater impact on the historical service life, thus providing data support for predicting the remaining service life of the ultraviolet lamp tube in the future.

[0022] Embodiment 2 is as Figure 1 shown. On the basis of Embodiment 1, a method for ultraviolet management in a microbiology laboratory according to an embodiment of the present invention includes: Step 2: If it is tight, obtain the life correlation coefficient, predict the current remaining life of the ultraviolet lamp tubes in the microbiology laboratory during the current period, and construct a replacement management sequence to be processed; In a preferred embodiment, if an associated tight signal is generated, calculate the average value of the adjacent change slopes corresponding to all adjacent analysis groups to obtain the life correlation coefficient, and construct a loss life prediction model. The corresponding equation is: , where is the life correlation coefficient, is a constant; Evenly divide the current period into several current time periods, obtain the usage times of any ultraviolet lamp tube within each current time period, and calculate the ratio with the duration of the current time period to obtain the unit usage frequency; Sum all the unit usage frequencies to obtain the current usage frequency; During the current period, obtain the current usage frequency of any ultraviolet lamp tube in the microbiology laboratory, and combine it with the life correlation coefficient, and input it into the remaining life prediction model to output the current loss life; It can be understood that the meaning represented by the current loss life is: during the current usage period, the degree of life consumption of the ultraviolet lamp tube due to the actual usage frequency, which is the core index for evaluating the remaining life of the lamp tube and formulating a replacement strategy. When predicting the life of the ultraviolet in the microbiology laboratory, the ultraviolet lamp tubes with low service life can be maintained and replaced in a timely manner, realizing the preventive management of the ultraviolet lamp tubes in the microbiology laboratory; Perform a difference process on the current loss life and the preset replacement loss life, take the absolute value, and obtain the current remaining life; Arrange all the ultraviolet lamp tubes in descending order according to the corresponding current remaining life to obtain a replacement management sequence to be processed; Step 3: Extract the irradiation areas corresponding to each ultraviolet lamp tube in the replacement management sequence to be processed in the microbiology laboratory, and perform a uniform and stable analysis on the irradiation intensity within each irradiation area, and mark the non-stable uniform area and the stable uniform area; Those skilled in the art can understand that an ultraviolet lamp is composed of multiple ultraviolet lamp tubes. When using the ultraviolet lamp to irradiate and disinfect the microbiology experiment area, each ultraviolet lamp tube in the ultraviolet lamp corresponds to an irradiation area within the microbiology experiment area; In a preferred embodiment, sequentially extract the irradiation areas corresponding to the ultraviolet lamp tubes in the replacement management sequence to be processed in descending order; Set an irradiation monitoring period and divide it into several irradiation monitoring nodes; It should be noted that the irradiation monitoring period is included in the current period; Obtain the irradiation intensity at each irradiation monitoring node for the irradiation area. Taking the X-axis as time and the Y-axis as the irradiation intensity, construct an irradiation intensity change curve; On the irradiation intensity change curve, mark the calibrated irradiation intensity on the Y-axis, and starting from the calibrated irradiation intensity on the Y-axis, draw a calibration intensity line parallel to the X-axis, and the calibration intensity line intersects the irradiation intensity change curve; Extract the coordinate points where the calibration intensity line intersects the irradiation intensity change curve, which are the intersection coordinate points; Respectively extract the local irradiation intensity change curves between adjacent intersection coordinate points as analysis sub-curves, and use the adjacent intersection coordinate points as the sub-curve start coordinate and sub-curve end coordinate of the analysis sub-curve respectively; Obtain the center point coordinate of the analysis sub-curve, and combine the sub-curve start coordinate and sub-curve end coordinate, and calculate through the three-point coordinate curvature calculation method to obtain the sub-curve curvature. The process is as follows: A1.

Generate an unstable uniformity signal and mark it as an unstable uniformity area; If the uniform stability value is greater than or equal to the uniform stability threshold, it indicates that the irradiation intensity of the analyzed irradiation area is stable and the difference in irradiation intensity compared to other irradiation areas within the microbial experiment area is small. A stable and uniform signal is generated and marked as a stable and uniform area; Step 4: Analyze the irradiation frequencies of the non-stable and uniform areas and the stable and uniform areas, screen out the areas to be swapped, and swap the ultraviolet lamps within the areas to be swapped and the areas to be swapped with; In a preferred embodiment, based on any stable and uniform area, obtain the current usage frequency of the corresponding ultraviolet lamp within the current cycle and compare it with the preset usage frequency.
