The present application is intended to cover any and all adaptive changes.

[0025] In one embodiment, Figure 1 A flowchart of a filter core monitoring method in an embodiment is shown in the figure. Figure 1 A filter core monitoring method is provided. The embodiment mainly applies the method to a filter core monitoring device, and the filter core monitoring device can be carried on any type of water dispenser device, such as a cold and hot direct drinking water dispenser with a heating water tank, a purified drinking water dispenser, a warm water drinking water dispenser, etc., or a drinking water dispenser without a heating water tank. The filter core monitoring method specifically includes the following steps:

[0026] In step S210, periodically obtain the periodic detection data of the water dispenser according to a preset period.

[0027] Specifically, the preset period can be set according to the actual application scene, such as 1 day, 3 days, 5 days, a week, a month, etc. The shorter the preset period corresponds to the length of time, the higher the monitoring accuracy of the filter core replacement time, and the filter core can be monitored in time whether it needs to be replaced. The periodic detection data of the water dispenser is used to reflect whether the filtering function of the filter core is effective. For different models of filter cores of the water dispenser, the manufacturer information and the use conditions under laboratory conditions (appearance during use, water tank scale stacking, etc.) of the filter core are recorded before the filter core is monitored, so as to be compared subsequently.

[0028] In step S220, a use state of the filter element is determined according to a comparison result between the periodic detection data and the reference detection data, wherein the periodic detection data comprises at least one of filter element detection data, water tank detection data, and outlet water detection data.

[0029] Specifically, the reference detection data is used to indicate that the filter element in the water dispenser has a qualified filtering function, the periodic detection data is used to judge the use state of the filter element based on the reference detection data, the periodic detection data is compared with the reference detection data, the periodic detection data comprises at least one of filter element detection data, water tank detection data, and outlet water detection data, the filter element detection data is detection data scanned for the filter element, and the filter element detection data at least comprises a filter element end face radius, a filter element surface protrusion thickness, a filter element surface recess depth, a filter element surface area color value, and filter element positioning data, the water tank detection data is detection data scanned for a heating water tank in the water dispenser, and the outlet water detection data is detection data for diagnosing outlet water detection of the water dispenser. The filter element surface scaling condition, the corrosion condition, and the installation condition can be determined through the filter element detection data, the scale condition in the heating water tank can be determined through the water tank detection data, and the outlet water quality condition of the water dispenser can be determined through the outlet water detection data.

[0030] The use state of the filter element can be determined based on the comparison result between the periodic detection data and the reference detection data, and the use state specifically can be to be replaced or to be used. When the use state is to be used, it indicates that the filter element currently still has filtering performance and can be used for water quality filtering. When the use state is to be replaced, it indicates that the filter element currently still has filtering performance but will soon lose the filtering performance, that is, the filter element is currently in a critical state of having filtering performance and losing filtering performance, and the filter element needs to be replaced.

[0031] In step S230, a filter element replacement prompt is sent when the use state is to be replaced.

[0032] Specifically, when it is monitored that the use state of the filter element is to be replaced, a filter element replacement prompt is sent. The filter element replacement prompt can be sent through a voice broadcast of the water dispenser and / or sent to a mobile terminal bound to the water dispenser through wireless communication to inform a user to replace the filter element in the water dispenser in time. The filter element replacement prompt does not need to be determined by a person, and is more accurate than a person determining a filter element replacement node, so as to solve the problems of wasting filtering use performance or affecting user health caused by a person replacing the filter element in the water dispenser too early or too late.

[0033] Reference Figure 3In the use state of the filter element is usable, according to the difference between the periodic detection data and the reference detection data, the usable duration of the filter element is determined and the usable duration is sent out, the usable duration of the filter element refers to the duration that the filter element can still be used, to prompt the user how long the filter element can be used before it needs to be replaced. According to the difference between the periodic detection data and the reference detection data, the usable duration of the filter element is determined and the usable duration is sent out, specifically including: determining the difference value interval corresponding to the candidate duration to which the difference value between each detection parameter in the periodic detection data and the corresponding detection parameter in the reference detection data belongs; determining the candidate duration with the smallest value in the plurality of candidate durations as the usable duration of the filter element. The detection parameters include filter element end face radius, filter element surface protrusion thickness, filter element surface recess depth, filter element surface area color value, etc., each detection parameter corresponds to a plurality of difference value intervals, different difference value intervals correspond to different candidate durations, the candidate duration is used to indicate the duration that the filter element can be used until the use state of the filter element changes to be replaced, and any change of the detection parameter beyond the corresponding threshold value will change the use state of the filter element to be replaced, so the candidate duration with the shortest duration is used as the usable duration of the filter element.

[0034] In one embodiment, before the periodic detection data of the water dispenser is periodically obtained according to the preset period, the method further comprises:

[0035] When the filter element is used for the first time, initial detection data of the filter element is obtained;

[0036] The preset detection requirement is obtained, and it is judged whether the initial detection data meets the preset detection requirement;

[0037] When the initial detection data meets the preset detection requirement, the initial detection data is taken as the filter element reference detection data, wherein the reference detection data includes the filter element reference detection data.

[0038] Specifically, when the filter element is a new filter element used for the first time, a scanner in the water dispenser is started to scan the filter element to obtain initial scanning data, and a camera is started to shoot the surface of the filter element to obtain initial image data, and the initial scanning data and the image data are combined to generate the initial detection data, which includes filter element end face radius, filter element surface protrusion thickness, filter element surface recess depth, filter element surface area color value, and filter element positioning data, i.e. the scanner can perform three-dimensional scanning on the filter element to scan out the structural parameters and position parameters of the filter element, i.e. the structural parameters include the above-mentioned filter element end face radius, filter element surface protrusion thickness, filter element surface recess depth, and filter element surface area color value, and the position parameter indicates the filter element positioning data, based on which whether the filter element has defects can be determined, and based on which whether the filter element installation is standard can be determined.

[0039] The preset detection requirement can be obtained from the filter core monitoring device locally, or obtained from a server through wireless communication. The preset detection requirement is used to indicate a qualified filter core factory standard. The initial detection data is matched with the preset detection requirement to determine whether the filter core in the water dispenser meets the qualified filter core factory standard. When the initial detection data meets the preset detection requirement, the initial detection data is used as reference detection data for monitoring the filter core usage state in the future. For initial detection data that does not meet the qualified filter core factory standard, the initial detection data is fed back to a mobile terminal bound to the water dispenser as after-sales data, informing the user that the filter core does not meet the factory standard and timely after-sales processing.

[0040] In one embodiment, when the initial detection data meets the preset detection requirement, the initial detection data is used as filter core reference detection data, including:

[0041] When the filter core end face radius in the initial detection data is within the radius threshold range, the filter core surface protrusion thickness in the initial detection data is less than or equal to the preset protrusion thickness, the filter core surface recess depth in the initial detection data is less than or equal to the preset recess depth, the filter core surface area color value in the initial detection data is within the corresponding color threshold range, and the matching degree between the filter core positioning data in the initial detection data and the preset positioning data is higher than the matching degree threshold, the initial detection data is used as filter core reference detection data.

[0042] Specifically, the filter core end face radius is used to reflect the thickness of the filter core to determine whether the filter core is corroded. The filter core surface protrusion thickness is used to reflect the adhesion of the filter core surface to the attached object. The filter core surface recess depth is used to reflect the filter core surface defect. The filter core surface area color value is used to reflect the corrosion and adhesion of the attached object. The color threshold range corresponding to the color value of different regions of the filter core surface is different or the same. Because the filter core at different positions contacts the water source in different order and frequency, the filter core surface at different regions has different filtering order and filtering frequency. Therefore, the color of different regions of the filter core surface is recorded and the corresponding color threshold range is provided.

[0043] The filter core end face radius in the initial detection data is within a radius threshold range, indicating that the filter core is not corroded. The filter core surface protrusion thickness in the initial detection data is less than or equal to a preset protrusion thickness, indicating that the filter core surface has no or less attachments. The filter core surface recess depth in the initial detection data is less than or equal to a preset recess depth, indicating that the filter core has no or less defects. The filter core surface area color value in the initial detection data is within a corresponding color threshold range, indicating that the filter core surface is not corroded or has a low degree of corrosion. The matching degree between the filter core positioning data in the initial detection data and the preset positioning data is higher than a matching degree threshold. The matching degree between the filter core positioning data and the preset positioning data indicates the overlap degree between the installation area indicated by the filter core positioning data and the installation area indicated by the preset positioning data. The higher the overlap degree, the higher the matching degree. The lower the overlap degree, the lower the matching degree. When the matching degree is higher than the matching degree threshold, it indicates that the filter core installation position meets the installation standard. When all the above conditions are met, that is, the initial detection data meets the preset detection requirements, the initial detection data is determined as the filter core reference detection data.

[0044] The radius threshold range, the preset protrusion thickness, the preset recess depth, the color threshold range, and the matching degree threshold can be customized according to application requirements. In this embodiment, the radius threshold range is 50 mm±2 mm, the preset protrusion thickness is 1 mm, the preset recess depth is 1 mm, the color threshold range is 128±10 (RGB value), and the matching degree threshold is 98%.

[0045] In one embodiment, the periodic detection data includes filter core detection data, and the use state of the filter core is determined according to the comparison result between the filter core detection data and the reference detection data, including:

[0046] When the difference between the filter core end face radius in the periodic detection data and the filter core end face radius in the filter core reference detection data is less than or equal to a first threshold, the difference between the filter core surface protrusion thickness in the periodic detection data and the filter core surface protrusion thickness in the filter core reference detection data is less than or equal to a second threshold, the difference between the filter core surface recess depth in the periodic detection data and the filter core surface recess depth in the filter core reference detection data is less than or equal to a third threshold, and the difference between the filter core surface area color value in the periodic detection data and the filter core surface area color value in the same area in the filter core reference detection data is less than or equal to a fourth threshold, the use state of the filter core is determined as usable; or,

[0047] If at least one of the following conditions is met, the filter element is determined to be in a condition requiring replacement: the difference between the filter element end face radius in the filter element test data and the filter element end face radius in the filter element reference test data is greater than a first threshold; the difference between the filter element surface protrusion thickness in the periodic test data and the filter element surface protrusion thickness in the filter element reference test data is greater than a second threshold; the difference between the filter element surface indentation depth in the periodic test data and the filter element surface indentation depth in the filter element reference test data is greater than a third threshold; or the difference between the color value of the filter element surface area in the periodic test data and the color value of the same area of ​​the filter element surface in the filter element reference test data is greater than a fourth threshold.

[0048] Specifically, the periodic test data is compared with the reference test data to determine whether the difference between the parameter values ​​in the periodic test data and the corresponding parameter values ​​in the reference test data is less than the corresponding threshold. The first threshold, second threshold, third threshold, and fourth threshold can all be customized according to actual needs. When the difference between the filter element end face radius in the filter element test data and the filter element end face radius in the reference test data is less than or equal to the first threshold, and the difference between the filter element surface protrusion thickness in the periodic test data and the filter element surface protrusion thickness in the reference test data is less than or equal to the second threshold, and the difference between the filter element surface indentation depth in the periodic test data and the filter element surface indentation depth in the reference test data is less than or equal to the third threshold, and the difference between the filter element surface area color value in the periodic test data and the filter element surface area color value in the same area in the reference test data is less than or equal to the fourth threshold, it indicates that the corrosion degree of the filter element surface is low, there are few deposits, and the filter element still has the filtering function. Therefore, the filter element is determined to be usable.

[0049] like Figure 2 As shown, when the difference between the end face radius of the filter element in the filter element test data and the end face radius of the filter element in the filter element reference test data is greater than a first threshold, it indicates that the filter element is severely corroded. When the difference between the thickness of the protrusions on the filter element surface in the filter element test data and the thickness of the protrusions on the filter element surface in the filter element reference test data is greater than a second threshold, it indicates that there are many deposits on the filter element surface. When the difference between the depth of the indentation on the filter element surface in the filter element test data and the depth of the indentation on the filter element surface in the filter element reference test data is greater than a third threshold, it indicates that the filter element is severely corroded or has serious defects. When the difference between the color value of the filter element surface area in the filter element test data and the color value of the same area of ​​the filter element surface in the filter element reference test data is greater than a fourth threshold, it indicates that the filter element surface is severely corroded, has many deposits, or is worn. The filter element's filtration function is about to be lost, and it will soon be unable to continue to filter the water. The filter element needs to be replaced, and its usage status is determined to be "needing replacement".

[0050] The fourth threshold value includes color threshold values corresponding to respective color channels, and the color value of the surface area of the filter element includes color values corresponding to three color channels, denoted as RGB values (red value, green value, and blue value), as shown in the following table:

[0051]

[0052] When the color value of the surface area of the filter element in the filter element detection data is compared with the color value of the surface area of the filter element in the filter element reference detection data, each color value in the color value of the surface area of the filter element in the filter element detection data is subtracted from the corresponding color value in the color value of the surface area of the filter element in the filter element reference detection data. For example, the color value of the surface area of the filter element in the filter element detection data is (10, 10, 258), and the corresponding color value of the surface area of the filter element in the filter element reference detection data is (0, 0, 255). The difference between the two color values of the surface area of the filter element is (10-0=10, 10-0=10, 258-255=3). Assuming that the fourth threshold value is (10, 10, 10), since 10=10, 10=10, and 3<10, it can be determined that the difference between the color value of the surface area of the filter element in the filter element detection data and the color value of the surface area of the filter element in the filter element reference detection data is less than or equal to the fourth threshold value. If the difference corresponding to at least one color channel is greater than the color threshold value of the corresponding color channel, it is determined that the difference between the color value of the surface area of the filter element in the filter element detection data and the color value of the surface area of the filter element in the filter element reference detection data is greater than the fourth threshold value.

[0053] The filter element detection data is compared with the filter element reference detection data to determine whether there is a significant color difference or appearance difference between the current filter element and the filter element before use. For example, the filter element is made of sponge material and has a fluffy appearance with many pores, but the adsorbed object has no small pores. It is determined whether there are many adsorbed objects adsorbed on the surface of the filter element or present in the pores of the filter element. The difference between the filter element detection data and the filter element reference detection data is used to determine whether the filter element has affected the filtering effect at the physical level and whether it needs to be replaced.

[0054] The image of the surface of the filter element captured by the camera is used to determine whether there are foreign objects adsorbed on the surface of the filter element. For example, there are particles in the water before purification. The determination method is an image processing algorithm. The positions of the protrusions in the scanning data are compared with the filter element before use to determine whether there is a significant color difference or appearance difference.

[0055] In one embodiment, the periodic detection data of the water dispenser is periodically obtained according to a preset period, including:

[0056] The type of the water tank of the water dispenser is obtained.

[0057] When the water tank type of the water dispenser is a heating water tank, the scanner is periodically started according to a first preset interval to scan the heating water tank in the water dispenser, and first scale data after the scanning of the heating water tank by the scanner is obtained, wherein the periodic detection data includes the first scale data, and the preset period includes the first preset interval.

[0058] According to a comparison result between the periodic detection data and reference detection data, a use state of the filter element is determined, including:

[0059] When a difference between the first scale data and first preset scale data in the preset detection requirement is greater than or equal to a first preset difference value, the use state of the filter element is determined as to be replaced, wherein the reference detection data further includes the first preset scale data.

[0060] Specifically, the water tank type of the water dispenser is a heating water tank, indicating that the water dispenser has a heating function, and the filtered water quality can be heated by using the heating water tank. The scanner is periodically started according to a first preset interval to scan the heating water tank in the water dispenser, and the scale of the heating water tank can be scanned, that is, the first scale data data2 is generated. The first preset scale data is used to indicate the detection data when there is no scale in the heating water tank in the laboratory environment. The peak area in the detection data is calculated to obtain the first preset scale data, which is recorded as data1. The difference between the first scale data and the first preset scale data in the preset detection requirement is greater than or equal to the first preset difference value, indicating that there is more scale in the heating water tank. The first preset difference value can be customized according to the actual application scenario. The smaller the first preset difference value, the easier it is to determine that the use state of the filter element is to be replaced. The larger the first preset difference value, the more difficult it is to determine that the use state of the filter element is to be replaced. The more scale is caused by the reduction of the filtering performance of the filter element, so the filter element needs to be replaced at this time, and the use state of the filter element is determined as to be replaced.

[0061] Generally, scale is mainly formed by calcium and magnesium ions to form carbonate, which is mostly white or light yellow, and appears in places that are easy to contact air, so only white color needs to be considered in this embodiment. If the scale is very thick, it will affect the replacement judgment result of the filter element. If the scale is not very thick but has accumulated, it will affect the qualified judgment result of the filter element.

[0062] In one embodiment, the periodic detection data of the water dispenser is periodically obtained according to a preset period, including:

[0063] The water tank type of the water dispenser is obtained.

[0064] when the water tank type of the water dispenser is a non-heating water tank, periodically starting the scanner to scan the hot water outlet of the water dispenser according to a second preset interval, and obtaining second scale data obtained after the scanner scans the hot water outlet, wherein the preset period includes the second preset interval, the second preset interval is longer than the first preset interval, and the water outlet detection data includes the second scale data;

[0065] According to the comparison result between the periodic detection data and the reference detection data, the use state of the filter element is determined, including:

[0066] When the difference between the second scale data and the second preset scale data in the preset detection requirement is greater than or equal to a third preset difference value, it is determined that the use state of the filter element is to be replaced, wherein the reference detection data further includes the second preset scale data.

[0067] Specifically, when the water tank type of the water dispenser is a non-heating water tank, it means that the water dispenser does not have a heating water tank, and the water dispenser does not have a heating function. Then, the scanner is periodically started to scan the hot water outlet of the water dispenser according to a second preset interval to detect the scale at the hot water outlet, i.e., to obtain second scale data. The second preset scale data is used to indicate the detection data of the hot water outlet of the water dispenser in a laboratory environment without scale. When the difference between the second scale data and the second preset scale data in the preset detection requirement is greater than or equal to a third preset difference value, it means that there is a lot of scale at the hot water outlet of the water dispenser. The third preset difference value can be customized according to the actual application scenario. A lot of scale is caused by low filter performance. Therefore, when there is a lot of scale at the hot water outlet, it is determined that the filter element needs to be replaced, i.e., the use state of the filter element is to be replaced.

[0068] The second preset interval is longer than the first preset interval because the hot water outlet is not easy to scale, while the water quality in the heating water tank is easy to scale. Therefore, the scale detection period of the heating water tank is shorter than that of the hot water outlet.

[0069] In one embodiment, after obtaining the first scale data obtained after the scanner scans the heating water tank or the second scale data obtained after the scanner scans the hot water outlet, the method further includes:

[0070] obtaining previous scale data scanned earlier than target scale data, wherein the scanning timestamp corresponding to the previous scale data is close to and earlier than the scanning timestamp corresponding to the target scale data, and the target scale data is the first scale data or the second scale data;

[0071] When the difference between the target scale data and the previous scale data is greater than or equal to a third preset difference value, it is determined that the use state of the filter element is to be replaced.

[0072] Specifically, according to the comparison result between the difference between the first scale data and the previous scale data scanned before the first scale data and the third preset difference value, or according to the comparison result between the difference between the second scale data and the previous scale data scanned before the second scale data and the third preset difference value, the use state of the filter element is determined. If the difference between the first scale data and the corresponding previous scale data is greater than the third preset difference value, or the difference between the second scale data and the corresponding previous scale data is greater than the third preset difference value, it indicates that the difference between the two time stamp adjacent scale data has changed, which may be due to the failure of the filter element causing the filtering performance to decrease. In order to ensure that the content of particulate impurities in the water is less, the use state of the filter element is also determined to be replaced, and the filter element with low filtering performance is replaced in time to avoid the user drinking drinking water with more particulate impurities.

[0073] In one embodiment, the periodic detection data of the water dispenser is periodically obtained according to a preset period, including:

[0074] The water outlet conductivity of the water dispenser is obtained according to a third preset interval, wherein the preset period further includes the third preset interval, and the water outlet detection data further includes the water outlet conductivity.

[0075] According to the comparison result between the periodic detection data and the reference detection data, the use state of the filter element is determined, including:

[0076] When the water outlet conductivity is greater than a conductivity threshold value, it is determined that the use state of the filter element is to be replaced, wherein the reference detection data further includes the conductivity threshold value.

[0077] Specifically, the conductivity sensor arranged at the water outlet of the water dispenser is used to collect the conductivity of the outlet water, and the conductivity sensor is controlled by a microcontroller or a processor to collect the conductivity of the outlet water. The conductivity of the outlet water of the water dispenser is used to indicate the mineral content in the outlet water of the water dispenser. The higher the conductivity of the outlet water, the higher the mineral content in the outlet water, which means that the filtering performance of the filter core is poorer. The conductivity of the outlet water is compared with the conductivity threshold value in the reference detection data to determine whether the mineral content in the outlet water of the water dispenser is too high. The conductivity threshold value can be a parameter value in the filter core reference detection data or a preconfigured parameter value. When the conductivity threshold value is a parameter value in the filter core reference detection data, it is used to indicate the conductivity of the outlet water detected when the water dispenser is used for the first time, i.e., the initial detection data includes the conductivity of the outlet water detected when the water dispenser is used for the first time. Since the initial detection data of the water dispenser meets the preset detection requirement, it also means that the filtering performance of the filter core is better. Therefore, the conductivity of the outlet water detected when the water dispenser is used for the first time can be used as the conductivity threshold value for subsequent judgment of the filtering performance of the filter core. When the conductivity of the outlet water is greater than the conductivity threshold value, it means that the mineral content in the outlet water is high, and the impurity particle content is high, which means that the filtering performance of the filter core is poor. It is determined that the use state of the filter core is to be replaced and a filter core replacement prompt is sent out to remind the user to replace the filter core in time to avoid the user drinking drinking water with high impurity particle content.

[0078] Based on the above filter core monitoring method, laboratory data is input before the water dispenser is used. The laboratory data is obtained by continuously replacing sample water dispensers in a flow line or sampling survey environment, and then scanning to finally train an ideal structure parameter threshold range, for example, the radius threshold range is 50mm±2mm, the highest surface irregular protrusion cannot exceed 1mm (i.e., the preset protrusion thickness is 1mm), etc. If the scanned data is within this interval range, it is considered to be a qualified product in shape. Then the color of the filter core is recorded. Specifically, the color of the object can be judged by using openCV digital image processing algorithm to pre-process the image scanned by the camera, and the image processing algorithm is used to divide it into N regions, and record the RGB number of each region, for example: (128±10, 128±10, 128±10). The best color threshold range is trained to obtain the ideal preset detection requirement.

[0079] When the new filter core is used for the first time, the detection is performed: directly compared with the laboratory data (i.e., the preset detection requirement), if the specifications, flat smoothness and surface area color of the filter core meet the preset detection requirement, it is considered that the "new filter core" is a qualified product.

[0080] For old filter cartridges that have been used for a period of time: These cartridges should have passed the testing procedures for new filter cartridges. After a period of use, the periodic test data should be compared with the reference test data. If the thickness of the raised areas on the filter cartridge surface in the periodic test data exceeds the preset thickness in the reference test data, it may be due to a large amount of contaminants such as sediment during the filtration process. If the depth of the indentations on the filter cartridge surface in the periodic test data exceeds the depth in the reference test data, it may be due to corrosive substances in the water source. If the color of the filter cartridge surface area in the periodic test data is significantly darker or lighter than the same area in the reference test data, it may be due to scale buildup. In summary, a low degree of matching between the periodic test data and the reference test data may lead to unqualified filtration results.
