Technical Field

[0001] The present application relates to the technical field of water purifiers, and in particular to an intelligent and accurate method, device, equipment and medium for calculating the life of a filter element. Background Art

[0002] As people's requirements for water purity continue to increase, filters are widely used in various water treatment equipment; in order to ensure that these devices can continuously and effectively remove impurities, pollutants, odors, etc. in water or air, it is necessary to accurately understand how long the filter can work normally under different working conditions. However, accurately estimating the service life of the filter in smart water purification equipment is still a major challenge, so how to accurately predict the service life of the filter has become a hot topic in current research.

[0003] Traditional filter life calculations mostly use simple time calculations or flow counting methods, that is, setting a fixed usage time or filtered water volume threshold, and prompting to replace the filter when it is reached.

[0004] However, the traditional method of calculating the life of the filter element can only perform simple calculations based on a single condition, resulting in inaccurate estimation of the actual remaining life of the filter element. Summary of the invention

[0120] The following combination Figure 1-Figure 3 This application is described in further detail.

[0121] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0122] The embodiment of the present application provides an intelligent and accurate method for calculating the life of a filter element, which is executed by an electronic device, which may be a server or a terminal device, wherein the server may be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device may be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server may be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application.

[0123] Reference Figure 1 The method comprises: step S101, step S102, step S103 and step S104, wherein:

[0124] Step S101, obtaining filtered water quality information and qualified water quality information, if the filtered water quality information is inconsistent with the qualified water quality information, determining the life of the first filter element.

[0125] In the embodiment of the present application, the filtered water quality information is the water quality information currently filtered by the water purifier, and the qualified water quality information is the water quality information after being filtered by the water purifier for the first time.

[0126] Specifically, the water inlet and outlet of each water purifier are equipped with monitoring equipment for detecting water quality. The monitoring equipment will collect the filtered water quality information of the water purifier when it is working in real time, and transmit the filtered water quality information to the electronic device; after receiving the filtered water quality information, the electronic device classifies and stores it in the database according to the working time and the water inlet and outlet, and sets the water quality information after the first filtration by the water purifier as qualified water quality information; then, the electronic device compares the filtered water quality information with the qualified water quality information. If the filtered water quality information is inconsistent with the qualified water quality information, it means that there are still impurities in the water after filtering through the filter element, and the water quality at this time cannot meet the use standard. Then, the electronic device determines the corresponding first filter element life by analyzing and processing the filtered water quality information.

[0127] Step S102: Obtain user usage information, and determine the life of the second filter element according to the user usage information.

[0128] In the embodiment of the present application, the user usage information includes the filter element usage time and the amount of water flowing through.

[0129] Specifically, each filter installation position of the water purifier is equipped with a monitoring device for monitoring user usage information. After receiving the user usage information transmitted by the monitoring device, the electronic device will store the information in a database one by one according to the filter usage time and the amount of water flowing through. The electronic device will then calculate the life of the second filter according to the second filter life calculation formula transmitted by the staff.

[0130] Calculate the second filter element life corresponding to the user usage information according to the following formula:

[0131]

[0132] Among them, n represents the user's filter usage time, m represents the water flow after n days, N represents the total number of days the filter is used, and M represents the total water flow after N days.

[0133] Step S103: Determine the life overlap degree according to the first filter element life and the second filter element life.

[0134] Specifically, the electronic device draws a curve image of the first filter element life in the database with the usage time as the x-axis and the first filter element service life as the y-axis, and sets the drawn image as the first curve image; at the same time, the electronic device draws a curve image of the second filter element life in the database with the usage time as the x-axis and the second filter element service life as the y-axis, and sets the drawn image as the second curve image; then the electronic device overlaps the first curve image with the second curve image, and uses an image algorithm to determine the degree of life overlap.

[0135] Step S104: If the life overlap is greater than or equal to the preset overlap, the target filter element life is determined.

[0136] Specifically, after determining the life overlap, the electronic device matches the life overlap with the preset overlap. If the life overlap is greater than the preset overlap, it means that the filtered water quality at this time meets the usage requirements of the staff; if the life overlap is less than the preset overlap, it means that the filtered water quality at this time does not meet the usage requirements of the staff at all, and the filter element has far exceeded its service life; if the life overlap is greater than or equal to the preset overlap, it means that the filtered water quality at this time just meets the usage requirements of the staff, and the filter element has reached its service life; then the electronic device sets the weighted average of the first filter element life corresponding to the preset overlap and the second filter element life corresponding to the filter element overlap as the target filter element life.

[0137] The embodiment of the present application provides an intelligent and accurate method for calculating the life of a filter element. After obtaining filtered water quality information and qualified water quality information, the filtered water quality information is compared with the qualified water quality information. If the filtered water quality information is inconsistent with the qualified water quality information, it means that there are still impurities in the water after being filtered by the filter element, and the water quality at this time cannot meet the use standard, and then the first filter element life is determined; thereafter, the user usage information is obtained, and the user usage information is analyzed and processed to calculate the corresponding second filter element life; after determining the second filter element life, the overlap between the first filter element life and the second filter element life is calculated to determine the life overlap, thereby avoiding the limitations and errors that may exist in a single judgment method; then, the life overlap is matched with the preset overlap, if the life overlap is greater than or equal to the preset overlap, it means that the filtered water quality at this time just meets the staff's use needs, and the filter element has reached its service life at this time, and the target filter element life is determined; thereby improving the accuracy of the filter element life calculation.

[0138] If the filtered water quality information is inconsistent with the qualified water quality information, the life of the first filter element is determined, including: splitting the filtered water quality information to obtain multiple sub-filtered water quality information; based on the qualified water quality information, determining the factors affecting the water quality; according to the factors affecting the water quality, determining the weight information; according to the weight information, determining the water quality score corresponding to each sub-filtered water quality information; if the water quality score is equal to the preset water quality score, obtaining the filter element usage time; according to the filter element usage time, obtaining the first filter element life.

[0139] In the embodiment of the present application, the qualified water quality information is the water quality information after being filtered by the water purifier for the first time.

[0140] Specifically, the electronic device splits and processes the filtered water quality information based on the water quality indicators set by the staff to obtain multiple sub-filtered water quality information. The water quality indicators include the dissolved solids (TDS) content, acidity (pH value), hardness (measured by the content of substances such as calcium carbonate), microbial content (such as the number of bacteria, viruses, etc.), and heavy metal content (such as the content of elements such as lead, mercury, and cadmium).

[0141] Further, the electronic device compares the qualified water quality information based on the water quality index, determines the factors affecting the water quality, and sets them as the factors affecting the water quality; the electronic device determines the importance of each factor affecting the water quality based on the water quality assessment knowledge, and sets the corresponding importance as the corresponding weight information, for example, the weight of dissolved solid content is 0.2, the weight of pH is 0.1, the weight of hardness is 0.15, the weight of microbial content is 0.3, and the weight of heavy metal content is 0.25. The electronic device calculates the water quality score corresponding to each sub-filtered water quality information according to the weight information corresponding to each factor affecting the water quality; then the electronic device compares the water quality score with the preset water quality score. If the water quality score is equal to the preset water quality score, it means that the water quality does not meet the staff's use standard at this time; then the electronic device generates a filter element usage time acquisition instruction, and transmits it to the filter element timing device, and the timing device then transmits the filter element usage time to the electronic device; after receiving the filter element usage time, the electronic device sets the filter element usage time corresponding to the filter element as the first filter element life.

[0142] Obtain user usage information, and determine the life of the second filter element according to the user usage information, including: substituting the filter element usage time and the water flow rate into the filter element life calculation formula to calculate and determine the life of the second filter element; determining the filter element calculation formula corresponding to the second filter element life, including:

[0143] Calculate the second filter element life corresponding to the user usage information according to the following formula:

[0144]

[0145] Among them, n represents the user's filter usage time, m represents the water flow after n days, N represents the total number of days the filter is used, and M represents the total water flow after N days.

[0146] In the embodiment of the present application, the user usage information includes the filter element usage time and the amount of water flowing through.

[0147] Specifically, after receiving the user usage information, the electronic device performs one-to-one classification and storage according to the filter element usage time and the water flow rate; then the electronic device screens and processes the filter element usage time and the water flow rate to determine the filter element usage time n, the water flow rate M after n days, the total number of filter element usage days N, and the total water flow rate M after N days corresponding to the filter element, and substitutes them into the formula to calculate the corresponding second filter element life.

[0148] Determine the second filter element life, and then also include: if the water quality score is less than the preset water quality score, obtain the filter element replacement information; substitute the filter element replacement information into the standard filter element life calculation formula to calculate and determine the standard filter element life; determine the standard filter element life calculation formula corresponding to the standard filter element life, including;

[0149] Calculate the standard filter element life corresponding to the standard filter element life according to the following formula:

[0150]

[0151]

[0152] in, Indicates the total number of days of use before replacing the filter element. Indicates the total amount of water flowing before replacing the filter element. Indicates standard filter element life.

[0153] In the embodiment of the present application, the filter element replacement information includes the total number of days of use and the total amount of water flowing before the filter element is replaced.

[0154] Specifically, the electronic device compares the water quality score with the preset water quality score. If the water quality score is less than the preset water quality score, it means that the water quality is poor and cannot meet the staff's needs. The electronic device then generates an instruction to obtain filter element replacement information and transmits it to the corresponding monitoring device. After receiving the instruction to obtain filter element replacement information, the monitoring device immediately transmits the filter element replacement information to the electronic device. After receiving the filter element replacement information, the electronic device immediately substitutes the filter element replacement information, including the total number of days of use before filter element replacement and the total water flow rate, into the formula for calculation to determine the standard filter element life.

[0155] Determine the life overlap degree according to the first filter element life and the second filter element life, including: draw a first curve image according to the first filter element life; draw a second curve image according to the second filter element life; determine the image overlap degree according to the first curve image and the second curve image; determine the life overlap degree according to the image overlap degree.

[0156] Specifically, the electronic device uses the number of days from the beginning of use to the end of use of the filter element as the x-axis and the first filter element life corresponding to the filter element as the y-axis to draw the first curve graph, assuming that the first filter element life is 150 days. When x=0, the filter element has just been used, and the remaining life ratio y=1, that is, the starting point of the curve is (0, 1); as time goes by, when x=150, the filter element life is exhausted, and the remaining life ratio y=0, that is, the end point is (150, 0); at the same time, the electronic device draws the second curve image in the above manner.

[0157] Furthermore, the electronic device draws the first curve image and the second curve image in the same coordinate system, and analyzes and processes the images to determine the image coincidence corresponding to the first curve image and the second curve image; then the electronic device matches the image coincidence with the corresponding filter element, and sets it as the life coincidence of the filter element.

[0158] Determining a target filter element life includes: determining a first weighted average value based on a first filter element life; determining a second weighted average value based on a second filter element life; and calculating the mean of the first weighted average value and the second weighted average value to determine the target filter element life.

[0159] In the embodiment of the present application, the first filter element life includes multiple lifespans, and the second filter element life includes multiple lifespans.

[0160] Specifically, the electronic device determines the relevant factors that affect the evaluation of the life of the first filter element based on historical data, and assigns corresponding weights to these relevant factors.
