Description

Technical Field

[0001] The present invention relates to the field of intelligent management technology, and specifically to an intelligent management system and method for microphone disinfection based on data analysis. Background Art

[0002] The existing irradiation intensity for disinfecting microphones is usually set manually. However, there are the following problems with manual setting: some viruses require a certain irradiation intensity to be eliminated. When the irradiation intensity is not enough, even if the irradiation time is extended, the energy threshold sufficient to destroy the virus structure and function cannot be reached, thereby failing to achieve the purpose of completely inactivating the virus, which poses a hidden danger to the hygiene of the microphone. Excessive irradiation intensity will affect the life of the disinfection equipment and damage the microphone material, causing material aging. Therefore, it is crucial to reasonably set the irradiation intensity of the disinfection equipment according to the use of the microphone. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent management system and method for microphone disinfection based on data analysis to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] The intelligent management method for microphone disinfection based on data analysis includes the following steps:

[0006] Step S100: collecting historical disinfection records of the disinfection device for disinfecting the microphone, the historical disinfection records including: the irradiation intensity during the disinfection process, the bacterial area of ​​the microphone head before and after disinfection, and the usage data of the microphone head before disinfection;

[0007] Step S200: marking the historical disinfection records according to the change of the bacterial area, and extracting the feature usage data corresponding to the marked historical disinfection records;

[0008] Step S300: Obtaining the degree to which the illumination intensity is affected by the usage according to the distribution of the characteristic usage data;

[0009] It should be noted that if the distribution of the characteristic distance value is relatively concentrated, it means that the characteristic distance value has a greater impact on the illumination intensity of the microphone. The marked disinfection process indicates that this part of the disinfection process is affected by the bacterial tolerance, resulting in an unsatisfactory disinfection effect. If the value of the variance D(FD) is small, it means that the illumination intensity is greatly affected by the use;

[0010] Step S400: taking the unsterilized microphone as the target microphone, collecting the usage time of the target microphone before disinfection and the usage data during the usage time, and obtaining the contamination degree coefficient of the target microphone according to the degree to which the illumination intensity is affected by the usage, and then determining whether the target microphone needs to be disinfected;

[0011] Step S500: If disinfection is required, a prompt is given, and the irradiation intensity of the disinfection device is set according to the degree to which the irradiation intensity is affected by use and the contamination degree coefficient.

[0012] Furthermore, the usage data of the microphone head before disinfection is obtained in step S100, including the following: the usage data is the distance value between the microphone head and the human mouth during use; a distance sensor is installed at the highest position in the microphone structure, and the time for transmitting and receiving sound waves from the distance sensor is obtained, thereby obtaining the distance value between the microphone head and the human mouth.

[0013] This solution is not limited to sensors, and can also obtain the highest position of the microphone structure and the distance from the human mouth in real time based on the monitoring video.

[0014] Further, step S200 includes the following steps:

[0015] Step S210: Obtain the bacterial area BC of the microphone head before and after the mth disinfection m and AC m , and obtain the bacterial residual ratio RAT m =1-AC m / BC m , if RAT is met 0 ≤RAT m ≤1, RAT 0 is the residual ratio threshold, then the mth disinfection record is marked;

[0016] Although disinfection equipment usually uses artificial settings for irradiation intensity and duration, in order to prevent premature aging of the equipment and not affect the service life of the equipment, when using ultraviolet disinfection equipment, it is not always turned to the most appropriate gear. Otherwise, the disinfection irradiation intensity or duration may be insufficient, resulting in an excessive number of bacteria after disinfection.

[0017] It should be noted that the usage data is the distance between the top of the microphone and the human mouth. Since this distance has a significant impact on microphone disinfection, when the distance is closer, the density of microorganisms on the microphone surface is higher, the risk of the microphone being contaminated with bacteria and viruses will increase, and it may also make disinfection more difficult. Because the amount of microorganisms attached may be greater, more effective disinfection methods and more frequent disinfection operations are needed to increase the intensity of disinfection to ensure the hygiene and safety of the microphone;

[0018] Step S220: Obtain the sound signal received by the microphone after the m-1th disinfection and before the mth disinfection, and collect the time period when the sound signal amplitude is greater than the sound signal amplitude threshold, and use the time period as the microphone usage time period UT corresponding to the mth disinfection record m ;

[0019] Step S230: The characteristic usage data is the characteristic distance value between the microphone head and the human mouth during use; obtain the usage time period UT m All distance values ​​within, and the distance value between the maximum and minimum distance values ​​is taken as the full distance segment, the full distance segment is evenly divided into Y sub-distance segments, the minimum distance value corresponding to a sub-distance segment is taken as the distance value of a sub-distance segment, there are a total of Y distance values, and the sub-distance segments are sorted from large to small according to the distance values;

[0020] Step S240: Wherein, L y is the distance value corresponding to the y-th sub-distance segment, and the feature weight corresponding to the y-th sub-distance segment is: Among them, 1≤y≤Y; the duration UT corresponding to the y-th sub-range y UT m Duration ratio DUR y =UT y / UT m ; Then the characteristic distance value corresponding to the mth disinfection process is obtained: And normalize the feature distance values.

[0021] The feature weight represents the weight corresponding to each section. Because the distance value may change accordingly due to different people's usage habits in each time period before disinfection, the distance value corresponding to the time period closest to disinfection is the most critical. The larger the y is, the smaller the distance value is, and the closer the human mouth is to the microphone. The closer the distance to the mouth is, the higher the risk of the microphone being contaminated with bacteria and viruses, so the weight is larger at this time. Feature distance value FD m Comprehensively considering the distance and time between the human mouth and the microphone head, when the distance is small and the time is longer, the feature weight is larger, indicating that the feature distance value is larger. In this embodiment, the number of Y segments can be determined according to the number of users and the usage time.

[0022] Further, step S300 includes the following steps: obtaining characteristic distance values ​​corresponding to all marked disinfection processes, and obtaining an average value corresponding to the characteristic distance values And variance D(FD), and get the evaluation coefficient E of the feature distance value FD =2-D(FD), 2≤E FD≤1; then according to the evaluation coefficient of the characteristic distance value, the degree of influence of the irradiation intensity on the use is obtained: DEG TH =log2E FD .

[0023] Further, step S400 includes the following steps:

[0024] Step S410: According to steps S220 to S240, obtain the characteristic distance value FD corresponding to the target microphone dm dm , according to the average value corresponding to the characteristic distance value in step S300 Then the illumination intensity value of the target microphone dm is obtained And normalize it;

[0025] Step S420: Establish a coordinate system with the duration of use as the horizontal coordinate and the illumination intensity value as the vertical coordinate; according to the illumination intensity value BTV of the target microphone dm dm and usage time UT dm , get the pollution degree coefficient of the target microphone dm: If PDC is met dm ≥1 and UT dm ≥UT 0 , then it is determined that the target microphone dm needs to be disinfected, where a and b are the correlation coefficients of the usage time and the bacterial tolerance value, a>b=1, UT 0 The usage duration threshold.

[0026] When the microphone is used for too long or the irradiation intensity reaches a high value, it means that it is time to disinfect. In this solution, the irradiation intensity value BTV dm and usage time UT dm , evaluate the contamination degree coefficient of the microphone, and then evaluate whether the microphone should be disinfected. In this scheme, the contamination degree coefficient PDC is obtained dm It is an ellipse formula, and the usage time is the horizontal axis. When the usage time is greater than the set usage time threshold, the pollution degree coefficient can be obtained by integrating the irradiation intensity value. When the pollution degree coefficient is greater than PDC dm ≥1 and UT dm ≥UT 0 , indicating that the degree of contamination has exceeded the range of the ellipse, and the usage time of the microphone has reached the threshold, and disinfection is required.

[0027] Furthermore, step S500 includes:

[0028] Step S510: According to step S210, obtain the first reliable disinfection process where all bacteria with a residual ratio less than the residual ratio threshold, if the irradiation intensity is affected by the use degree DEG TH >DEG0 , DEG 0 is the impact degree threshold, and according to the characteristic distance values ​​corresponding to all the first reliable disinfection processes, the characteristic distance value set RFD is obtained according to the characteristic distance values ​​from small to large; the characteristic distance threshold is set, and the distance values ​​less than the characteristic distance value FD in the set RFD are dm The corresponding disinfection process set as RDP 1 , the disinfection process set corresponding to the characteristic distance threshold is taken as RDP 2 , and RDP 1 ∪RDP 2 The corresponding minimum value of the irradiation intensity during the corresponding disinfection process is used as the irradiation intensity of the disinfection device;

[0029] Step S420: Otherwise, if DEG TH ≤DEG 0 , obtain the contamination degree coefficients corresponding to all first reliable disinfection processes, and obtain the contamination degree coefficients that are not less than the contamination degree coefficient PDC dm , and the usage time is not less than the usage time threshold UT 0 The second reliable disinfection process is obtained, and the disinfection irradiation intensity corresponding to the minimum value of the bacterial residual ratio in the second reliable disinfection process is used as the irradiation intensity of the disinfection device.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-Figure 2 The present invention provides an intelligent management system and method for microphone disinfection based on data analysis, and the corresponding flowchart of the intelligent management method for microphone disinfection based on data analysis is as follows: Figure 1 As shown. The following steps are included:

[0050] Step S100: Collect historical disinfection records of the disinfection device for disinfecting the microphone, the historical disinfection records include: the irradiation intensity during the disinfection process, the bacterial area of ​​the microphone head before and after disinfection, and the usage data of the microphone head before disinfection.

[0051] The usage data is the distance between the microphone head and the human mouth during use; a distance sensor is installed at the highest position in the microphone structure to obtain the time it takes for the sound wave to be emitted and received from the distance sensor, and then the distance between the microphone head and the human mouth is obtained. An ultrasonic sensor is installed on the top of the microphone to obtain the distance from the human mouth by emitting ultrasonic pulses and measuring their round-trip time.

[0052] Step S200: marking the historical disinfection records according to the change of the bacterial area, and extracting the feature usage data corresponding to the marked historical disinfection records.

[0053] Step S210: Obtain the bacterial area BC of the microphone head before and after the mth disinfection m and AC m , and obtain the bacterial residual ratio RAT m=1-AC m / BC m , if RAT is met 0 ≤RAT m ≤1, RAT 0 is the residual ratio threshold, the mth disinfection record will be marked.

[0054] The bacterial residual ratio represents the residual state of the microphone after disinfection. 0 ≤RAT m ≤1, indicating that the microphone disinfection is not very ideal, and there are still a lot of bacteria. In this solution, this part of the disinfection process is marked and analyzed in the next step. In this embodiment, RAT 0 =0.5.

[0055] Although disinfection equipment usually uses artificial settings for irradiation intensity and duration, in order to prevent premature aging of the equipment and not affect the service life of the equipment, when using ultraviolet disinfection equipment, it is not always turned to the most appropriate gear. Otherwise, the disinfection irradiation intensity or duration may be insufficient, resulting in an excessive number of bacteria after disinfection.

[0056] It should be noted that in this embodiment, the data used is the distance between the top of the microphone and the human mouth. Since this distance has a significant impact on microphone disinfection, when the distance is closer, the density of microorganisms on the microphone surface is higher, the risk of the microphone being contaminated with bacteria and viruses will increase, and it may also make disinfection more difficult. Because the amount of microorganisms attached may be greater, more effective disinfection methods and more frequent disinfection operations are required to increase the intensity of disinfection in order to ensure the hygiene and safety of the microphone.

[0057] Step S220: Obtain the sound signal received by the microphone after the m-1th disinfection and before the mth disinfection, and collect the time period when the sound signal amplitude is greater than the sound signal amplitude threshold, and use the time period as the microphone usage time period UT corresponding to the mth disinfection record m The effective sound time period is the time period when the human body makes sounds.

[0058] Step S230: The characteristic usage data is the characteristic distance value between the microphone head and the human mouth during use; obtain the usage time period UT m All distance values ​​within, and the distance value between the maximum and minimum distance values ​​is taken as the full distance segment, the full distance segment is evenly divided into Y sub-distance segments, the minimum distance value corresponding to a sub-distance segment is taken as the distance value of a sub-distance segment, there are a total of Y distance values, and the sub-distance segments are sorted from large to small according to the distance values.

[0059] Step S240: Wherein, L yis the distance value corresponding to the y-th sub-distance segment, and the feature weight corresponding to the y-th sub-distance segment is: Among them, 1≤y≤Y; the duration UT corresponding to the y-th sub-range y UT m Duration ratio DUR y =UT y / UT m ; Then the characteristic distance value corresponding to the mth disinfection process is obtained: And normalize the feature distance values.

[0060] The feature weight represents the weight corresponding to each section. Because the distance value may change accordingly due to different people's usage habits in each time period before disinfection, the distance value corresponding to the time period closest to disinfection is the most critical. The larger the y is, the smaller the distance value is, and the closer the human mouth is to the microphone. The closer the distance to the mouth is, the higher the risk of the microphone being contaminated with bacteria and viruses, so the weight is larger at this time. Feature distance value FD m Comprehensively considering the distance and time between the human mouth and the microphone head, when the distance is small and the time is longer, the feature weight is larger, indicating that the feature distance value is larger. In this embodiment, the number of Y segments can be determined according to the number of users and the usage time.

[0061] The purpose of normalization is: since each disinfection process may vary greatly, for example, the disinfection time is too long or the distance is too close, the deviations between the characteristic distance values ​​calculated in this way may be too large and not representative, so normalization is needed.

[0062] Step S300: Obtain the degree to which the illumination intensity is affected by the usage according to the distribution of the characteristic usage data.

[0063] Get the characteristic distance values ​​corresponding to all marked disinfection processes, and get the average value corresponding to the characteristic distance values And variance D(FD), and get the evaluation coefficient E of the feature distance value FD =2-D(FD), 2≤E FD ≤1; then according to the evaluation coefficient of the characteristic distance value, the degree of influence of the irradiation intensity on the use is obtained: DEG TH =log2E FD .

[0064] It should be noted that if the distribution of the characteristic distance value is relatively concentrated, it means that the characteristic distance value has a greater impact on the illumination intensity of the microphone. The marked disinfection process indicates that this part of the disinfection process is affected by the bacterial tolerance, resulting in an unsatisfactory disinfection effect. If the value of the variance D(FD) is small, it means that the illumination intensity is greatly affected by the use.

[0065] Step S400: Take the unsterilized microphone as the target microphone, collect the usage time of the target microphone before disinfection, and the usage data during the usage time, and obtain the contamination degree coefficient of the target microphone according to the degree to which the illumination intensity is affected by usage, and then determine whether the target microphone needs to be disinfected.

[0066] Step S410: According to steps S220 to S240, obtain the characteristic distance value FD corresponding to the target microphone dm dm , according to the average value corresponding to the characteristic distance value in step S300 Then the illumination intensity value of the target microphone dm is obtained And normalize it.

[0067] Step S420: Establish a coordinate system with the duration of use as the horizontal coordinate and the illumination intensity value as the vertical coordinate; according to the illumination intensity value BTV of the target microphone dm dm and usage time UT dm , get the pollution degree coefficient of the target microphone dm: If PDC is met dm ≥1 and UT dm ≥UT 0 , then it is determined that the target microphone dm needs to be disinfected, where a and b are the correlation coefficients of the usage time and the bacterial tolerance value, a>b=1, UT 0 The usage duration threshold.

[0068] When the microphone is used for too long or the irradiation intensity reaches a high value, it means that it is time to disinfect. In this solution, the irradiation intensity value BTV dm and usage time UT dm , evaluate the contamination degree coefficient of the microphone, and then evaluate whether the microphone should be disinfected. In this scheme, the contamination degree coefficient PDC is obtained dm It is an ellipse formula, and the usage time is the horizontal axis. When the usage time is greater than the set usage time threshold, the pollution degree coefficient can be obtained by integrating the irradiation intensity value. When the pollution degree coefficient is greater than PDC dm ≥1 and UT dm ≥UT 0 , indicating that the degree of contamination has exceeded the range of the ellipse, and the usage time of the microphone has reached the threshold, and disinfection is required.

[0069] Step S500: If disinfection is required, a prompt is given, and the irradiation intensity of the disinfection device is set according to the degree to which the irradiation intensity is affected by use and the contamination degree coefficient.

[0070] Step S510: According to step S210, obtain the first reliable disinfection process where all bacteria with a residual ratio less than the residual ratio threshold, if the irradiation intensity is affected by the use degree DEG TH >DEG 0 , DEG 0 is the impact degree threshold, and according to the characteristic distance values ​​corresponding to all the first reliable disinfection processes, the characteristic distance value set RFD is obtained according to the characteristic distance values ​​from small to large; the characteristic distance threshold is set, and the distance values ​​less than the characteristic distance value FD in the set RFD are dm The corresponding disinfection process set as RDP 1 , the disinfection process set corresponding to the characteristic distance threshold is taken as RDP 2 , and RDP 1 ∪RDP 2 The corresponding minimum value of the irradiation intensity during the corresponding disinfection process is used as the irradiation intensity of the disinfection device.

[0071] In this embodiment, the feature distance threshold is determined according to the set RFD, all feature distance values ​​in the set RFD are obtained, and the maximum feature distance value corresponding to less than 30% of the set RFD is used as the feature distance threshold.

[0072] Step S420: Otherwise, if DEG TH ≤DEG 0 , obtain the contamination degree coefficients corresponding to all first reliable disinfection processes, and obtain the contamination degree coefficients that are not less than the contamination degree coefficient PDC dm , and the usage time is not less than the usage time threshold UT 0 The second reliable disinfection process is obtained, and the disinfection irradiation intensity corresponding to the minimum value of the bacterial residual ratio in the second reliable disinfection process is used as the irradiation intensity of the disinfection device.
