Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a method for detecting the life of a filter element of a water purifier according to the present application.
The present embodiments provide embodiments of a method of detecting a life of a water purifier cartridge, it being noted that although a logical sequence is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than that shown or described herein.
The method for detecting the service life of the filter element of the water purifier is applied to the cloud, and comprises the following steps:
step S10, acquiring the power-off time of the water purifier;
in this embodiment, the high in the clouds can carry out radio communication with at least one water purifier, simultaneously, high in the clouds and water purifier all can calculate the remaining life-span of water purifier filter core, and when the water purifier outage, the decay life-span of filter core can't be calculated to the water purifier, need calculate the decay life-span of filter core by the high in the clouds this moment. The water purifier is powered off mainly in two cases, one is to manually cut off the power supply of the water purifier, such as when a user goes out for business trip or on vacation; the other is that the power supply is cut off due to special conditions, such as lightning stroke, short circuit, overlarge line load and the like, and the overlarge current suddenly appears in the line, so that the switching equipment trips.
When the water purifier is powered off, the water purifier and the cloud end are in a disconnected state, namely the water purifier is in an offline state, at the moment, the cloud end automatically records the corresponding time T1 when the water purifier is powered off and the residual service life L1 of the filter element, and when the water purifier is powered on again and is successful in networking with the cloud end, the cloud end automatically records the corresponding time T2 when the water purifier is powered on and the residual service life L2 of the filter element. Then, the power-off duration of the water purifier is calculated according to the time T1 and the time T2, and it can be understood that the power-off duration is the time difference between the power-off and the power-on of the water purifier, for example, the power-off duration=t2—t1 of the water purifier.
Step S20, determining a filter element life attenuation value of the filter element in the power-off period according to the power-off time length and a life attenuation coefficient corresponding to the filter element of the water purifier;
in this embodiment, after determining the power-off duration of the water purifier, the cloud end obtains a pre-stored life attenuation coefficient of the filter element, where the life attenuation coefficient is a corresponding life attenuation coefficient of the filter element when the water purifier is in a power-off state. Then, calculating the life attenuation value of the filter element during the power failure of the water purifier through the power failure time length and the life attenuation coefficient, for example, assuming that the power failure time length is (T2-T1) and the life attenuation coefficient is a, the life attenuation value of the filter element is a (T2-T1), namely, the product of the power failure time length and the life attenuation coefficient is taken as the life attenuation value of the filter element of the water purifier.
The water purifier is in an off-line state and generally comprises two conditions, wherein one is in a power-off state, the other is in a network-off state, the network-off state refers to the condition that the network of the water purifier is abnormal and cannot be in wireless communication with a cloud, but the power supply of the water purifier is not cut off, namely the water purifier can normally work in the network-off state and the residual service life of the filter element can be normally calculated. In an embodiment, after the water purifier is in an offline state, the cloud end detects the network state of the water purifier in real time, and when the water purifier is detected to be in an online state, that is, the water purifier and the cloud end are successfully networked again, at this time, the cloud end receives the first residual life of the filter element uploaded by the water purifier through the wireless network, then compares the first residual life with the second residual life of the filter element before the water purifier is in the offline state, and if the first residual life is inconsistent with the second residual life, it is indicated that the water purifier is in the offline state due to network abnormality, and in the offline state, the water purifier can calculate the residual life of the filter element in real time according to the use condition of the water purifier. At this time, the cloud end updates the second remaining life according to the first remaining life, that is, replaces the prestored second remaining life with the first remaining life, so that the first remaining life is used as the remaining life of the water purifier displayed in the cloud end. If the first remaining life is consistent with the second remaining life, it is indicated that the water purifier is in an offline state because the power failure is cut off, and in the offline state, the water purifier cannot calculate the remaining life of the filter element, and at this time, the cloud end can determine the life attenuation value of the filter element of the water purifier during the power failure according to the power failure duration and the life attenuation coefficient corresponding to the filter element.
And step S30, determining the residual life of the filter element according to the life attenuation value of the filter element, and sending the residual life to the water purifier so that the residual life before power failure is updated according to the residual life when the water purifier is powered on.
In this embodiment, after determining the filter element life attenuation value, the cloud obtains the difference between the remaining life of the water purifier before power-off and the filter element life attenuation value, and then uses the difference as the remaining life of the filter element after power-on, for example, assuming that the remaining life of the water purifier before power-off is L1 and the filter element life attenuation value is a (T2-T1), the remaining life of the filter element after power-on is L1-a (T2-T1). After the residual service life of the filter element after power-on is determined, the cloud end can send the residual service life value to the water purifier so that the water purifier can update the residual service life before power-off according to the residual service life.
The embodiment provides a method for detecting the service life of a filter element of a water purifier so as to calculate the service life attenuation of the filter element of the water purifier during power failure. Because the water purifier can not calculate the outage duration, the embodiment moves the calculation of the outage duration of the water purifier to the cloud end, the cloud end calculates the service life attenuation value of the filter element according to the outage duration and the service life attenuation coefficient of the water purifier, then determines the residual service life of the filter element according to the service life attenuation value of the filter element, and synchronizes the residual service life to the water purifier, so that the problem that the service life of the filter element can not be calculated due to outage of the water purifier is solved, and the accuracy of the service life calculation of the filter element is improved.
Further, referring to fig. 3, a second embodiment of a method for detecting the life of a filter element of a water purifier according to the present application is provided.
The method for detecting the service life of the filter element of the water purifier is applied to the water purifier, and comprises the following steps:
step S40, receiving the residual service life of the filter element sent by the cloud;
because the life information of the filter element displayed by the water purifier and the cloud end is the same, the water purifier receives the residual life of the filter element sent by the cloud end through the wireless network after being electrified again and being connected with the cloud end successfully.
And step S50, updating the residual life before power failure according to the residual life.
The water purifier updates the remaining life stored before the power-off according to the received remaining life, that is, replaces the remaining life stored before the power-off with the remaining life, for example, assuming that the remaining life is 70%, the remaining life stored before the power-off is 80%, and the updated remaining life is 70%. Further, the water purifier displays life information of the filter element in real time, wherein the life information includes a remaining life percentage of the filter element and a remaining life number of days, wherein the remaining life number is determined according to the remaining life percentage, and in an embodiment, assuming that the remaining life percentage is 90% and the standard life number of the filter element is 100 days, the remaining life percentage of the filter element is the product of the remaining life percentage and the standard life number of the filter element, that is, 90% by 100=90 days.
Under the condition that the water purifier is powered on and is successfully networked with the cloud end, the residual life of the filter element is synchronized to the cloud end in real time, in one embodiment, after the fact that the water purifier is re-networked with the cloud end is detected, the water purifier automatically obtains the third residual life of the filter element in an offline state, and then the third residual life is sent to the cloud end so that the cloud end can update the second residual life of the water purifier before the water purifier is in the offline state according to the third residual life.
After the filter element is used for a long time, the filter element can lose the water purifying capacity due to the blockage of trapped matters, the multiplication of microorganisms trapped under the filter element and the like, namely the service life of the filter element is expired, so that the filter element needs to be replaced in time in order to ensure the safety of drinking water. In one embodiment, when the remaining life of the filter element reaches a predetermined life range (e.g., 0% -2%), the water purifier outputs a prompt for replacement of the filter element to prompt the user to replace the filter element.
According to the embodiment, the residual service life of the filter element sent by the cloud is received, and then, the residual service life before power failure is updated based on the residual service life, so that the problem that the service life of the filter element cannot be calculated due to power failure of the water purifier is solved by moving the calculation of the power failure duration of the water purifier to the cloud, and the accuracy of calculation of the service life of the filter element is improved.
Further, referring to fig. 3, a third embodiment of a method for detecting the life of a filter element of a water purifier according to the present application is provided.
The method for detecting the service life of the filter element of the water purifier is applied to the water purifier, and the method further comprises the following steps:
step S60, acquiring the flushing coefficient of the filter element, the preset water purifying amount, the daily water purifying amount and the water quality information of water to be purified;
in this embodiment, the water purifier acquires the flushing coefficient of the pre-stored filter element, the preset water purifying amount, the daily water purifying amount, and the water quality information of the water to be purified, wherein:
the flushing coefficient of the filter element can be revised according to the different film rolling modes of the filter element and the different electric control flushing programs;
the preset water purifying amount refers to the laboratory standard filtered water amount;
the daily water purification amount refers to the use intensity of the filter element, namely the daily purified water amount, and the daily water purification amount is determined in the following way: calculating data once at 0 point every day, calculating data for the second time at 24 points every day, and taking the difference value of the data for the second time as daily water purifying quantity, namely the actual total water purifying quantity (L) of the equipment in the past 24 hours;
the water quality information of the water to be purified comprises a water quality coefficient and a total dissolved solids value (TDS value), and the total dissolved solids value comprises an actual inflow TDS value (inflow total dissolved solids value) and a standard laboratory TDS value (preset total dissolved solids value), wherein the water quality coefficient is preset; the total dissolved solids (Total dissolved solids, TDS) are milligrams of dissolved solids in 1 liter of water, and the higher the TDS value is, the more the dissolved solids are contained in the water, and the water purifying section and the water outlet section of the filter element are respectively provided with a TDS monitoring sensor for detecting the TDS value of inflow water and the TDS value of outflow water.
Step S70, determining the attenuation duration required by the filter element attenuation preset value according to the flushing coefficient, the preset water purifying amount, the daily water purifying amount and the water quality information;
the water purifier calculates the attenuation duration required by the filter element attenuation preset value (such as 1%) according to the flushing coefficient, the laboratory standard filtered water quantity, the daily purified water quantity, the water quality coefficient, the actual water inlet TDS value and the standard laboratory TDS value. In one embodiment, a first difference between the TDS value of the incoming water and the TDS value of the standard laboratory is calculated, a first product of the first difference, the water quality coefficient and the flushing coefficient is calculated, a second difference between the first coefficient and the first product is calculated, a second product of the second difference and the standard filtered water volume of the laboratory is calculated, a quotient between the second product, the daily purified water volume and the second coefficient is calculated, and finally the quotient is used as a duration required by a filter element attenuation preset value. Referring to formula (1), the number of days of decay corresponding to 1% decay in filter cartridge life can be calculated based on formula (1):
T0＝(1-(W1-W0)*X*C)*L0/Y/100 (1)
in the formula (1), T0 refers to the number of decay days (i.e., decay time period) corresponding to 1% lifetime calculated from the past 24 hours of use;
w1 is the actual water inflow TDS value;
w0 is the index laboratory TDS value;
x is the water quality coefficient;
c refers to a flushing coefficient (revised according to the different membrane rolling modes of the filter element and the electric control flushing program);
l0 refers to the laboratory standard filtered water quantity (preset net water quantity);
y is daily water purification quantity, namely actual use intensity, and is defined according to 24-hour water quantity change;
1 refers to a first coefficient;
100 refers to the second coefficient.
When the TDS value is abnormally high and the water consumption is small, the attenuation days corresponding to 1% calculated based on the formula (1) are abnormal, that is, the difference between the attenuation days corresponding to 1% and the standard attenuation days corresponding to 1% is large, at this time, the water purifier automatically adjusts the TDS value and the daily water consumption by using prestored data, for example, when the actual TDS is greater than 350, 350 is taken for calculation, and when the actual TDS is less than 50, 50 is taken for calculation. When the actual use intensity is more than 16L/day, 16L is taken for calculation, and when the actual use intensity is less than 8L, 8L/day is taken for calculation, wherein the pre-stored TDS data and daily water purification amount data are determined according to historical data.
In order to avoid abnormal attenuation of the filter element and ensure the regularity of an attenuation curve, the lowest attenuation standard is determined, in one embodiment, when the second duration is smaller than the preset duration, the shortest second duration required for attenuating the preset value in the second preset time is obtained according to the preset total life of the filter element, and then the second duration is updated according to the shortest second duration. For example, assuming that 1% of the corresponding decay days < (standard life days +.100) calculated based on equation (1), the life calculation fails, at which point the water purifier forcibly modifies T0 by the shortest life setting. Wherein the shortest lifetime setting is related to the lifetime of the filter element (preset total lifetime), e.g. assuming a lifetime of the filter element of 1-2 years, the shortest lifetime setting t0= (standard lifetime days-40)/100; assuming that the life span of the filter element is 2-4 years, the shortest life span is set as T0= (standard life span number-75)/100; assuming that the life span of the filter element is 4-5 years, the shortest life setting t0= (standard life days-90)/100. In this embodiment, a mode of percentage life decay is adopted, wherein the decay days corresponding to 1% life are dynamically changed, so that the decay of new life is also dynamically changed, but the standard life is the laboratory standard life, namely the life calculated under the standard simulation environment. Referring to formula (2), standard days of decay corresponding to 1% decay in filter cartridge life can be calculated based on formula (2):
T1＝(1-(W2-W0)*X*C)*L0/Y1 (2)
in the formula (2), T1 refers to a standard decay number of days corresponding to 1% lifetime calculated from the past 24 hours of use;
w2 is the TDS value of the inflow water in the index test environment;
w0 is the index laboratory TDS value;
x is the water quality coefficient;
c refers to a flushing coefficient (revised according to the different membrane rolling modes of the filter element and the electric control flushing program);
l0 refers to the laboratory standard filtered water quantity (preset net water quantity);
y1 is the standard water amount of 10L/day.
And step S80, determining the residual life of the filter element according to the attenuation duration.
The life decay rule determines whether the natural use days exceed the interval T0, and the life percentage is decayed by 1% every time the natural use days exceed 1 time T0. In one embodiment, it is assumed that the filter life is updated from 85% to 84% at 24 points, at this time, the water purifier recalculates T0 at the next 24 hours according to the usage conditions, and the calculated T0 is assumed to be 3, i.e., the number of days of decay corresponding to a 1% decrease in life is 3 days, at this time, the T0 value for each 24 hours is calculated, and the T0 for 3 consecutive days is assumed<3, at this time, the filter cartridge life was reduced by 1% at 24 points on the third day, that is, by 83%. Suppose T0 on day three is 4, T0 ＞ 3, the life of the filter element is reduced at 24 points on the third day, and the filter element is kept 84 percent, and the T0 on the fourth day is assumed to be 2, namely T0<3, at this time, the filter cartridge life was reduced by 1% at 24 points on the fourth day, that is, by 83%. Wherein, each 1% corresponding T0 is dynamically changed, and at the next 24 hours when the life percentage decays by 1%, the T0 value is recalculated, for example, the filter life is assumed to be updated from 85% to 84% at 24 points of No. 1, at this time, the decay days corresponding to the decrease of 1% in the filter life are recalculated at No. 2, the T0 calculated by No. 2 is compared with the T0 calculated by the subsequent calculation, and if the natural use days after No. 2 and No. 2 exceed T0, the life percentage decays by 1%, for example, the filter life is updated from 84% to 83% at 24 points of No. 6, the decay days corresponding to the decrease of 1% in the filter life are recalculated again at No. 7, and so on.
Attenuation is carried out for nth time, the service life percentage is attenuated for n percent, and the service life days are dynamically updated according to the new percentage. Wherein, the life percentage and life days formula is calculated as follows:
percent residual life= (1-1% ×n) (3)
Number of remaining life = number of standard life days x percentage remaining life (4)
In the formula (3), N is the nth interval attenuation.
Based on the above formula, the remaining life percentage and the remaining life days of the filter element can be calculated, for example, assuming that the number of decays of the filter element is 30 times and the standard life days is 100 days, the corresponding remaining life percentage= (1-1% ×30) =70% and remaining life days=100×70% =70 days.
According to the embodiment, daily water purifying amounts of different users are introduced, and meanwhile, the service life of the filter element in the interval is calculated by combining 24-hour water quality dynamic calculation, so that the real-time calculation of the service life of the filter element is realized.
In order to better explain the method for detecting the service life of the filter element of the water purifier, reference is made to fig. 5, and fig. 5 is a schematic operation flow diagram of the method for detecting the service life of the filter element of the water purifier.
It should be noted that, the apparatus of this embodiment refers to a water purifying apparatus, including a household water purifier and a large-sized water purifier, where the household water purifier refers to a water quality processor for a household or a drinking water terminal; the large-scale water purifier is a water quality treatment device which is used by groups and has large volume and is not suitable for being moved.
In this embodiment, when the device is normally powered on, the local device calculates the remaining life of the filter element according to the usage conditions (including the actual water inlet TDS value, the standard laboratory TDS value, the water quality coefficient, the flushing coefficient, the laboratory standard filtered water amount, the daily purified water amount, etc.), and at the same time, the cloud end synchronizes the remaining life L1 of the filter element of the local device in real time. When equipment is powered off and offline, the cloud records equipment offline time T1, and when the equipment is detected to be powered on and online again, the cloud records equipment online time T2 and obtains the residual service life L2 of the filter element uploaded by the local end of the equipment. Then, the remaining life L1 is compared with the remaining life L2, if l1=l2, it is indicated that the water purifier is in an offline state because the power outage is cut off, and in this offline state, the water purifier cannot calculate the remaining life of the filter element, at this time, the cloud end determines the filter element life attenuation value of the water purifier during the power outage according to the power outage duration and the life attenuation coefficient of the filter element life of the water purifier, determines the remaining life of the filter element based on the filter element life attenuation value, for example, the filter element life attenuation value calculated by the cloud end is a (T2-T1), and then synchronously updates the remaining life of the filter element at the cloud end and the equipment end to be L1-a (T2-T1). If L1 is not equal to L2, the water purifier is in an off-line state due to network abnormality, and the water purifier can calculate the residual life of the filter element in real time according to the use condition of the water purifier. At this time, the cloud updates the remaining life of the filter element to L2. After the device is powered on and connected to the internet, the local end of the device continues to calculate the residual service life of the filter element.
According to the embodiment, the calculation of the outage duration of the water purifier is moved to the cloud, the cloud calculates the life attenuation value of the filter element according to the outage duration and the life attenuation coefficient of the water purifier, then the residual life of the filter element is determined according to the life attenuation value of the filter element, and the residual life is synchronously given to the water purifier, so that the problem that the life of the filter element cannot be calculated due to outage of the water purifier is solved, and the accuracy of calculating the life of the filter element is improved.
