Description

Technical Field

[0001] The invention belongs to the technical field of microbiological laboratory equipment management, in particular to an ultraviolet management method and system for a microbiological laboratory. Background Art

[0002] Ultraviolet lamps play a vital role in the daily operations of microbiology laboratories. The ultraviolet light they produce effectively kills microorganisms in the air and on surfaces, providing essential disinfection for the experimental environment and ensuring the accuracy and reliability of experimental results. However, as consumables, UV lamps have a limited lifespan. Their disinfection effectiveness gradually decreases with age, necessitating regular replacement.

[0003] Existing technologies only focus on the cumulative usage time of individual lamps, ignoring the correlation between the historical service life ratio and the historical usage frequency ratio of lamps in the same batch. This fails to accurately reflect the impact of historical usage frequency on historical service life, resulting in a lack of sufficient data support for the prediction of the remaining service life of lamps, making it difficult to accurately determine the timing of lamp replacement.

[0004] Secondly, existing lamp replacement strategies are usually based solely on usage duration or intensity thresholds, without considering the accelerated loss of lamp life due to differences in usage frequency in different areas. There is a lack of a lamp load balancing strategy based on usage frequency, and it is impossible to reduce pressure in high-frequency areas by interchanging lamps, resulting in uneven distribution of lamp life across the laboratory.

[0005] To this end, the present invention provides an ultraviolet management method and system for a microbiology laboratory. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0008] In a first aspect, a method for ultraviolet management in a microbiology laboratory comprises:

[0009] Conduct correlation analysis on the historical service life ratio and historical usage frequency ratio of UV lamps during the historical usage cycle to assess whether there is a close correlation;

[0010] If they are close, the life correlation coefficient is obtained to predict the current remaining life of the UV lamp in the current cycle and to build a replacement management sequence;

[0011] Analyze the irradiation intensity of the UV lamps in the replacement management sequence, evaluate the uniformity and stability of the irradiation intensity, and screen out unstable and stable uniform areas;

[0012] The irradiation frequency of the unstable uniform area and the stable uniform area is analyzed to screen out the area to be exchanged and the area to be exchanged, and the ultraviolet lamps in the area to be exchanged and the area to be exchanged are exchanged.

[0013] As a further solution of the present invention, the process of evaluating whether the association is close is as follows:

[0014] The ratio of the historical usage time of each ultraviolet lamp to the total cycle length of the historical usage cycle is obtained as the historical service life ratio. The ratio of the historical usage times of each ultraviolet lamp to the total historical usage times of all ultraviolet lamps is obtained as the historical usage frequency ratio. An association analysis change curve is constructed, and adjacent coordinate points are combined to obtain adjacent analysis groups. The association analysis value is obtained by outputting the Manhattan distance calculation formula. If it is less than or equal to the association analysis threshold, a close association signal is generated.

[0015] As a further solution of the present invention, the process of obtaining the life correlation coefficient and constructing the loss life prediction model is as follows:

[0016] Based on the closely correlated signals, the adjacent change slopes corresponding to all adjacent analysis groups are averaged to obtain the lifespan correlation coefficient;

[0017] Based on the life correlation coefficient, a loss life prediction model is constructed, and the corresponding equation is: ,in, is the lifespan correlation coefficient, is a constant.

[0018] As a further solution of the present invention, the current remaining life is predicted and a replacement management sequence is constructed. The process is as follows:

[0019] Divide the current cycle into several current time periods, obtain the ratio of the number of times any UV lamp is used in each current time period to the duration of the current time period, obtain the unit usage frequency, and sum them up to obtain the current usage frequency;

[0020] Input the current usage frequency into the loss life prediction model to obtain the current loss life, and perform subtraction processing on it with the preset replacement loss life, take the absolute value, and obtain the current remaining life;

[0021] Arrange all ultraviolet lamps in descending order according to their current remaining lifespans to obtain a management sequence to be replaced.

[0022] As a further solution of the present invention, the irradiation intensity of the ultraviolet lamps in the replacement management sequence is analyzed to obtain the intensity stability value. The process is as follows:

[0023] Set the irradiation monitoring cycle and divide it into several irradiation monitoring nodes. Obtain the irradiation intensity of the irradiated area at each irradiation monitoring node, construct an irradiation intensity change curve, and draw a calibration intensity line that intersects the irradiation intensity change curve to obtain the intersection coordinate point.

[0024] The local irradiation intensity variation curves between adjacent intersecting coordinate points are extracted respectively as analysis sub-curves, and the adjacent intersecting coordinate points are used as the sub-curve starting coordinates and sub-curve ending coordinates of the analysis sub-curve respectively. Combined with the center point coordinates of the analysis sub-curve, the curvature of the sub-curve is calculated by the three-point coordinate curvature calculation method;

[0025] The sub-curve curvatures corresponding to all analysis sub-curves are counted, and the sub-curve curvatures corresponding to adjacent analysis sub-curves are input into the Manhattan distance formula to obtain the intensity stability value as output.

[0026] As a further solution of the present invention, the irradiation intensity of the ultraviolet lamps in the replacement management sequence is analyzed to obtain the intensity uniformity value, and the process is as follows:

[0027] In the management sequence to be replaced, the irradiation areas corresponding to the adjacent ultraviolet lamps are obtained, and the irradiation intensities corresponding to the irradiation areas are obtained respectively, and difference processing is performed, and the absolute value is taken to obtain the adjacent intensity difference;

[0028] The standard deviation of adjacent intensity differences is calculated and the output is the intensity uniformity value.

[0029] As a further solution of the present invention, the uniformity and stability of the irradiation intensity are evaluated, and the screening process of the unstable uniform area and the stable uniform area is as follows:

[0030] The uniform intensity value and the stable intensity value are summed and the uniform stable intensity value is output;

[0031] If the uniform stability value is less than the uniform stability threshold, it is an unstable uniform area;

[0032] If the uniform stability value is greater than or equal to the uniform stability threshold, it is a stable uniform area.

[0033] As a further solution of the present invention, the screening process of the regions to be exchanged is as follows:

[0034] Based on any stable and uniform area, the current usage frequency of the corresponding ultraviolet lamp in the current cycle is obtained and compared with the preset usage frequency. If the current usage frequency is less than or equal to the preset usage frequency, it is a low-dependence lamp, and the corresponding irradiation area is marked as the area to be interchanged.

[0035] As a further solution of the present invention, the ultraviolet lamps in the area to be exchanged and the area to be exchanged are exchanged, and the process is as follows:

[0036] Based on the intensity uniformity value, a size comparison is performed, and all low-dependence lamps and UV lamps corresponding to the unstable uniform area are sorted from large to small to obtain the sequence to be interchanged and the sequence to be interchanged;

[0037] The microbial experimental area corresponding to the unstable uniform area is extracted as the exchanged area, and the intensity uniformity values ​​of adjacent stable uniform areas are subtracted and the absolute value is taken to obtain the stable uniform intensity difference;

[0038] Extract the maximum stable uniform intensity difference and the minimum stable uniform intensity difference to form a stable uniform intensity difference interval;

[0039] Arbitrarily obtain the intensity average value of the low-dependence lamp in the sequence to be exchanged, and perform difference calculation with the intensity average value corresponding to the adjacent ultraviolet lamp in the microbiological experimental area of ​​the ultraviolet lamp in the sequence to be exchanged, and output the difference value to be replaced;

[0040] If the difference value of the ultraviolet lamp to be replaced exists in the stable uniform intensity difference range, the ultraviolet lamp is interchanged.

[0041] In a second aspect, a UV management system for a microbiology laboratory comprises:

[0042] Correlation analysis module: within the historical usage cycle, the historical service life ratio and historical usage frequency ratio of each UV lamp in the same batch are analyzed to evaluate whether there is a close correlation;

[0043] Life prediction module: If it is close, the life correlation coefficient is obtained to predict the current remaining life of the ultraviolet lamp in the microbiology laboratory in the current cycle, and a replacement management sequence is constructed;

[0044] Intensity monitoring module: analyzes the irradiation intensity of the UV lamps in the replacement management sequence, evaluates the uniformity and stability of the irradiation intensity, and screens out unstable and stable uniform areas;

[0045] Strategy exchange module: Analyze the irradiation frequency of the unstable uniform area and the stable uniform area, screen out the area to be exchanged and the area to be exchanged, and exchange the ultraviolet lamps in the area to be exchanged and the area to be exchanged.

[0046] The beneficial effects of the present invention are as follows:

[0047] 1. The present invention performs a correlation analysis on the historical service life ratio and the historical usage frequency ratio of each ultraviolet lamp in the same batch within a historical usage cycle to obtain a correlation analysis value. The correlation analysis value not only reflects that the historical service life ratio and the historical usage frequency ratio of each ultraviolet lamp in the same batch are closely correlated, but also indirectly reflects that the historical usage frequency of the ultraviolet lamp has a significant impact on the historical service life, thereby providing data support for subsequent prediction of the remaining service life of the ultraviolet lamp;

[0048] 2. The present invention extracts the irradiation area corresponding to each ultraviolet lamp in the management sequence to be replaced in the microbiology laboratory, and performs irradiation intensity analysis to screen out unstable uniform areas and stable uniform areas, thereby not only reflecting the impact of the ultraviolet lamp life on the stability and uniformity of the ultraviolet lamp irradiation intensity, but also providing technical support for actively maintaining the service life of the ultraviolet lamp by identifying abnormal areas in advance. Irradiation frequency analysis is performed on the unstable uniform area and the stable uniform area, and the area to be interchanged and the area to be interchanged are screened and interchanged, thereby not only identifying the excessive loss of ultraviolet lamp life caused by high-frequency use, but also introducing low-frequency lamps to share the load of high-dependence areas, reducing the use frequency of the original high-dependence lamps, delaying their performance degradation, and reducing the frequency of replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The present invention will be further described below with reference to the accompanying drawings.

[0050] Figure 1 It is a flow chart of the steps of an ultraviolet management method for a microbiology laboratory of the present invention;

[0051] Figure 2 The present invention is a schematic diagram of an ultraviolet management system for a microbiology laboratory. DETAILED DESCRIPTION

[0052] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0053] Example 1: Figure 1As shown, in an embodiment of the present invention, a method for managing ultraviolet light in a microbiology laboratory is described. Since the ultraviolet light in the microbiology laboratory is emitted by the installed ultraviolet lamps, the same batch of ultraviolet lamps are used for different periods of time or frequencies in the daily laboratory. If the same batch of ultraviolet lamps are used for a long time or are used frequently, the service life of the ultraviolet lamps will be greatly affected, and ultimately the ultraviolet lamps will not be able to disinfect the microbiology laboratory effectively by emitting ultraviolet light. 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. The method includes the following steps:

[0054] Step 1: Conduct a correlation analysis on the historical service life ratio and historical usage frequency ratio of each UV lamp in the same batch within the historical usage cycle to assess whether there is a close correlation;

[0055] In a preferred embodiment, the historical service life ratio of the ultraviolet lamp is obtained as follows:

[0056] During the historical use cycle, the historical use time of each UV lamp in the same batch of UV lamps is recorded, and the ratio is calculated with the total cycle length of the historical use cycle to output the historical service life ratio;

[0057] The historical usage frequency ratio of the UV lamp is obtained as follows:

[0058] Count the number of times each UV lamp has been used in its historical use cycle, and calculate the ratio of the number to the total number of times all UV lamps have been used in its historical use cycle, and output the historical use frequency ratio;

[0059] With the historical usage frequency ratio of the UV lamps as the X-axis and the historical service life ratio as the Y-axis, a correlation analysis change curve is constructed based on the historical service life ratio and historical usage frequency ratio of the UV lamps in the same batch.

[0060] On the correlation analysis change curve, adjacent coordinate points are combined to obtain adjacent analysis groups;

[0061] In the adjacent analysis group, the X-axis coordinates and Y-axis coordinates of the adjacent coordinate points are extracted respectively, and the adjacent change slope is obtained by the slope calculation formula;

[0062] Input the adjacent change slopes corresponding to multiple adjacent analysis groups into the Manhattan distance formula and output the association analysis value ;

[0063] Specifically, the Manhattan distance formula is: , calculate the correlation analysis value ,in, Expressed as the total number of adjacent analysis groups, Expressed as The adjacent change slopes corresponding to the adjacent analysis groups are: Expressed as The adjacent change slopes corresponding to the adjacent analysis groups;

[0064] It can be understood that the correlation analysis value is obtained by obtaining the adjacent change slopes between adjacent analysis groups using the Manhattan distance formula. Since the principle of the Manhattan distance formula is to measure the distance between two points in a multi-dimensional space, and the historical usage frequency and historical service life corresponding to each ultraviolet light are a coordinate point on the correlation analysis change curve, therefore, by processing the adjacent change slopes corresponding to multiple groups of adjacent coordinate combinations using the Manhattan distance formula, it is possible to quantify the degree of correlation between the historical usage frequency and historical service life corresponding to the ultraviolet light, and thus identify the degree of influence of the historical usage frequency on the historical service life based on the degree of correlation between the two, providing data support for the subsequent prediction of the remaining service life of the ultraviolet lamp;

[0065] The association analysis value is compared with the association analysis threshold value, and the process is as follows:

[0066] If the correlation analysis value is greater than the correlation analysis threshold, it means that the correlation between the historical frequency of use and the historical service life is not close, and a non-close correlation signal is generated;

[0067] If the correlation analysis value is less than or equal to the correlation analysis threshold, it means that the correlation between the historical usage frequency and the historical service life is relatively close, and a close correlation signal is generated;

[0068] This embodiment can be summarized as follows: within a historical usage cycle, a historical service life ratio and a historical usage frequency ratio of each UV lamp in the same batch of UV lamps are analyzed for a degree of correlation to obtain a correlation analysis value. The correlation analysis value not only reflects that the historical service life ratio and the historical usage frequency ratio of each UV lamp in the same batch are closely correlated, but also indirectly reflects that the historical usage frequency of the UV lamp has a significant impact on the historical service life, thereby providing data support for subsequent prediction of the remaining service life of the UV lamp.

[0069] Example 2 Figure 1 As shown, based on Example 1, an ultraviolet management method for a microbiology laboratory according to an embodiment of the present invention includes:

[0070] Step 2: If the relationship is close, obtain the lifespan correlation coefficient, predict the current remaining lifespan of the ultraviolet lamps in the microbiology laboratory within the current cycle, and construct a replacement management sequence;

[0071] In a preferred embodiment, if a closely correlated signal is generated, the adjacent change slopes corresponding to all adjacent analysis groups are averaged to obtain the life correlation coefficient, and a loss life prediction model is constructed. The corresponding equation is: ,in, is the lifespan correlation coefficient, is a constant;

[0072] Divide the current cycle into several current time periods, obtain the number of times any UV lamp is used in each current time period, and calculate the ratio with the duration of the current time period to obtain the unit usage frequency;

[0073] Sum up the usage frequencies of all units to get the current usage frequency;

[0074] In the current cycle, the current usage frequency of any UV lamp in the microbiology laboratory is obtained, and combined with the life correlation coefficient, it is input into the remaining life prediction model, and the output is the current loss life;

[0075] It is understandable that the current loss of life means the degree of life loss of the UV lamp due to actual usage frequency during the current use cycle. It is the core indicator for evaluating the remaining life of the lamp and formulating replacement strategies. When predicting the life of UV lamps in microbiology laboratories, it is possible to timely maintain and replace UV lamps with low service life, thus achieving preventive management of UV lamps in microbiology laboratories.

[0076] The current loss life is subtracted from the preset replacement loss life, and the absolute value is taken to obtain the current remaining life;

[0077] Arrange all UV lamps in descending order according to their current remaining lifespan to obtain a management sequence to be replaced;

[0078] Step 3: Extract the irradiation area in the microbiology laboratory corresponding to each UV lamp in the management sequence to be replaced, and perform a uniformity and stability analysis of the irradiation intensity in each irradiation area, marking the unstable uniform area and the stable uniform area;

[0079] It is understood by those skilled in the art that an ultraviolet lamp is composed of a plurality of ultraviolet lamp tubes. When the ultraviolet lamp is used to irradiate and disinfect the microbial experimental area, each ultraviolet lamp tube in the ultraviolet lamp irradiates a corresponding irradiation area within the microbial experimental area.

[0080] In a preferred embodiment, the irradiation areas in the microbiology laboratory corresponding to the ultraviolet lamps are sequentially extracted in descending order within the associated sequence to be replaced;

[0081] Set the irradiation monitoring cycle and divide it into several irradiation monitoring nodes;

[0082] It should be noted that the irradiation monitoring period is included in the current period;

[0083] Obtain the irradiation intensity of the irradiated area at each irradiation monitoring node, with the X-axis representing time and the Y-axis representing irradiation intensity, and construct an irradiation intensity change curve;

[0084] On the irradiation intensity variation curve, mark the calibrated irradiation intensity on the Y axis, and draw a calibrated intensity line parallel to the X axis with the calibrated irradiation intensity on the Y axis as the starting point, and the calibrated intensity line intersects with the irradiation intensity variation curve;

[0085] Extract the coordinate point where the calibration intensity line intersects the irradiation intensity variation curve, which is the intersection coordinate point;

[0086] Extracting local irradiation intensity variation curves between adjacent intersecting coordinate points as analysis sub-curves, and using the adjacent intersecting coordinate points as sub-curve starting coordinates and sub-curve ending coordinates of the analysis sub-curves;

[0087] Get the coordinates of the center point of the analysis sub-curve, and combine them with the coordinates of the sub-curve start point and the sub-curve end point to calculate the curvature of the sub-curve using the three-point coordinate curvature calculation method. The process is as follows:

[0088] A1, according to the coordinate point distance formula, obtain the coordinate distance between the sub-curve starting point coordinate and the sub-curve end point coordinate to obtain the starting and ending distance ;

[0089] Specifically, ,in,( , ) represents the starting coordinates of the sub-curve, ( , ) represents the coordinates of the end point of the sub-curve;

[0090] A2, according to the coordinate point distance formula, obtains the coordinate distance between the starting point coordinate of the sub-curve and the midpoint coordinate of the sub-curve, and obtains the starting-midpoint distance ;

[0091] Specifically, ,in,( , ) represents the starting coordinates of the sub-curve, ( , ) is represented as the coordinates of the midpoint of the sub-curve;

[0092] A3, according to the coordinate point distance formula, obtain the coordinate distance between the sub-curve end point coordinate and the sub-curve midpoint coordinate to obtain the end-to-midpoint distance ;

[0093] Specifically, ,in,( , ) represents the coordinates of the end point of the sub-curve, ( , ) is represented as the coordinates of the midpoint of the sub-curve;

[0094] A4, using Heron's formula, calculates the area of ​​the triangle formed by the coordinates of the sub-curve's starting point, end point, and center point. The process is as follows:

[0095] Specifically, ,in, Expressed as the start-end distance, Indicates the starting distance, It is expressed as the final center distance;

[0096] ;

[0097] A5, according to the curvature calculation formula, obtain the radius of the triangle's circumcircle and take the reciprocal as the sub-curve curvature , the process is as follows:

[0098] Specifically, ,in, It is expressed as the area of ​​the triangle formed by the coordinates of the sub-curve starting point, the sub-curve ending point and the center point of the analysis sub-curve. Expressed as the start-end distance, Indicates the starting distance, Expressed as the final center distance;

[0099] The curvature of the sub-curves corresponding to all the analysis sub-curves is counted, and the curvature of the sub-curves corresponding to the adjacent analysis sub-curves is input into the Manhattan distance formula to output the intensity stability value. ;

[0100] Specifically, ,in, Expressed as the total amount of sub-curve curvature, Expressed as The curvature of the sub-curve, Expressed as Curvature of the sub-curve;

[0101] In the management sequence to be replaced, the irradiation areas corresponding to the adjacent ultraviolet lamps are obtained, and the irradiation intensities corresponding to the irradiation areas are obtained respectively, and difference processing is performed, and the absolute value is taken to obtain the adjacent intensity difference;

[0102] It should be noted that adjacent UV lamps are in the same UV lamp, and the irradiation area is also in the same microbiological experimental area;

[0103] Calculate the standard deviation of adjacent intensity differences and output the intensity uniformity value;

[0104] The uniform intensity value and the stable intensity value are summed and the uniform stable intensity value is output;

[0105] It can be understood that the meaning of the uniform stability value is: a quantitative indicator that comprehensively reflects the stability of the irradiation intensity of the UV lamp irradiation area and the uniformity between areas in the microbiology laboratory, and indirectly reflects that the life of the UV lamp has a great impact on its irradiation intensity, providing data support for the subsequent replacement or interchange of UV lamps;

[0106] If the uniform stability value is less than the uniform stability threshold, it means that the irradiation intensity of the analyzed irradiation area is unstable and has a large difference compared with the irradiation intensity of other irradiation areas in the microbiological experimental area, generating an unstable uniform signal and marking it as an unstable uniform area;

[0107] If the uniform stability value is greater than or equal to the uniform stability threshold, it means that the irradiation intensity of the analyzed irradiation area is stable, and the difference in irradiation intensity compared with other irradiation areas in the microbiological experimental area is small, a stable uniform signal is generated, and it is marked as a stable uniform area;

[0108] Step 4: Analyze the irradiation frequency of the unstable uniform area and the stable uniform area, select the area to be exchanged, and exchange the UV lamps in the area to be exchanged with the UV lamps in the area to be exchanged;

[0109] In a preferred embodiment, based on any stable and uniform area, the current usage frequency of the corresponding ultraviolet lamp in the current cycle is obtained and compared with the preset usage frequency. The process is as follows:

[0110] If the current usage frequency is greater than the preset usage frequency, it means that the UV lamp is used more frequently in the current cycle and is a high-dependency lamp;

[0111] If the current usage frequency is less than or equal to the preset usage frequency, it means that the UV lamp is used less frequently in the current cycle and is a low-dependency lamp, and the corresponding irradiation area is marked as an area to be exchanged;

[0112] Compare the average intensity values ​​of the low-dependence lamps during the irradiation monitoring period and sort them from large to small to obtain a sequence to be exchanged;

[0113] The unstable uniform area is used as the area to be exchanged, and the intensity uniformity value of the ultraviolet lamp corresponding to each unstable uniform area during the irradiation monitoring period is obtained, and the values ​​are compared and sorted from large to small to obtain the sequence to be exchanged;

[0114] Extract the microbial experimental area corresponding to the unstable uniform area as the exchanged area;

[0115] Difference is made between the intensity average values ​​of adjacent stable and uniform areas within the area to be exchanged, and the absolute value is taken to obtain the stable and uniform intensity difference;

[0116] Extract the maximum stable uniform intensity difference and the minimum stable uniform intensity difference to form a stable uniform intensity difference interval;

[0117] Arbitrarily obtain the intensity average value of the low-dependence lamp in the sequence to be exchanged, and perform difference calculation with the intensity average value corresponding to the adjacent ultraviolet lamp in the microbiological experimental area of ​​the ultraviolet lamp in the sequence to be exchanged, and output the difference value to be replaced;

[0118] If the difference value of the UV lamp to be replaced exists in the stable uniform intensity difference range, the UV lamp is interchanged;

[0119] If the difference value to be replaced does not exist in the stable uniform intensity difference range, the ultraviolet lamp is replaced;

[0120] This embodiment can be summarized as follows: extracting the irradiation area corresponding to each ultraviolet lamp in the management sequence to be replaced in the microbiology laboratory, and performing irradiation intensity analysis to screen out unstable and uniform areas and stable and uniform areas, thereby not only reflecting the impact of the ultraviolet lamp life on the stability and uniformity of the ultraviolet lamp irradiation intensity, but also providing technical support for proactively maintaining the service life of the ultraviolet lamp by identifying abnormal areas in advance, performing irradiation frequency analysis on the unstable and uniform areas and the stable and uniform areas, screening out the areas to be interchanged and the areas to be interchanged, and then performing the interchange, thereby not only identifying the excessive loss of ultraviolet lamp life caused by high-frequency use, but also introducing low-frequency lamps to share the load of high-dependence areas, reducing the use frequency of the original high-dependence lamps, delaying their performance degradation, and reducing the frequency of replacement.

The process is as follows: Based on the intensity uniformity value, a size comparison is performed, and all low-dependence lamps and UV lamps corresponding to the unstable uniform area are sorted from large to small to obtain the sequence to be interchanged and the sequence to be interchanged; Difference is made between the intensity average values ​​of adjacent stable and uniform areas within the area to be exchanged, and the absolute value is taken to obtain the stable and 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 average value of the low-dependence lamp in the sequence to be exchanged, and perform difference calculation with the intensity average value corresponding to the adjacent ultraviolet lamp in the microbiological experimental area of ​​the ultraviolet lamp in the sequence to be exchanged, and output the difference value to be replaced; If the difference value of the ultraviolet lamp to be replaced exists in the stable uniform intensity difference range, the ultraviolet lamp is interchanged.

8. A UV management system for a microbiology laboratory, characterized by: Correlation analysis module: within the historical usage cycle, the historical service life ratio and historical usage frequency ratio of each UV lamp in the same batch are analyzed to evaluate whether there is a close correlation; To assess whether the association is close, the process is as follows: Obtain the ratio of the historical usage time of each UV lamp to the total duration of its historical usage cycle as the historical service life ratio. Obtain the ratio of the historical usage times of each UV lamp to the total historical usage times of all UV lamps as the historical usage frequency ratio. Build an association analysis change curve, combine adjacent coordinate points, and obtain an adjacent analysis group. Obtain an association analysis value using the Manhattan distance calculation formula. If it is less than or equal to the association analysis threshold, a close association signal is generated. Life prediction module: If it is close, the life correlation coefficient is obtained to predict the current remaining life of the ultraviolet lamp in the microbiology laboratory in the current cycle, and a replacement management sequence is constructed; Intensity monitoring module: analyzes the irradiation intensity of the UV lamps in the replacement management sequence, evaluates the uniformity and stability of the irradiation intensity, and screens out unstable and stable uniform areas; Strategy exchange module: Analyze the irradiation frequency of the unstable uniform area and the stable uniform area, select the area to be exchanged, and exchange the UV lamps in the area to be exchanged with those in the area to be exchanged; Obtain the current usage frequency of the UV lamp corresponding to the stable and uniform area 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-dependence lamp and the corresponding irradiation area is marked as the area to be exchanged; The microbial experimental area corresponding to the unstable uniform area is extracted as the exchanged area.
