Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a water quality detection method for a water purifier includes steps S100, S200, and S300.
And S100, acquiring water quality operation parameters of the water purifier.
Specifically, the water quality operation parameters are acquired by a data acquisition device arranged on the water purifier. The water quality operation parameters are the raw water state data of the water inlet pipeline of the water purifier, the concentrated water flow after passing through the reverse osmosis membrane, the pure water flow and other parameters when the water purifier operates. The water quality monitoring system comprises a water purifier, a data acquisition device, a data processing host and a data processing host, wherein the water purifier is arranged in the water purifier, the data acquisition device is arranged on the water purifier, and is used for acquiring water quality operation parameters in real time, and the acquired water quality operation parameters are sent to the data processing host of the water purifier, so that the data processing host can process the water quality operation parameters to obtain the operation influence condition of the water quality state of the water purifier on. It should be noted that the types of parameters specifically included in the water quality operation parameters are not unique, different types of data collectors can be used for collecting parameters of each type, and meanwhile, the specific setting position of each data collector is not unique as long as various different parameters can be reasonably collected.
And step S200, obtaining the Langerial saturation index of the water purifier according to the water quality operation parameters.
Specifically, the Langelier Saturation Index (LSI) is a value obtained by subtracting a saturated PH value from a PH value measured in a water sample. When calcium carbonate is saturated in water, the heavy calcium carbonate is not decomposed into calcium carbonate nor is calcium carbonate dissolved, and the PH at this time is called saturated PH, which is represented by PHs, i.e., LSI — PHn — PHs, where PHn represents the measured PH of the water sample. In general LSI analysis, if the pH value of a water sample is greater than PHs and LSI is positive, calcium carbonate is precipitated from the water, and the water belongs to scaling type water; when LSI is negative, the original scale layer will be dissolved away, so that the raw material is exposed in water to be eroded, and the water is called erosion type water; when LSI is equal to zero, water is saturated and this water is stable water. Therefore, the LSI value can be used for intuitively evaluating the scaling capacity of raw water in the water purifier and whether the electromagnetic valve of the wastewater is blocked or not.
And step S300, obtaining and pushing the water quality scaling capacity of the water purifier and the blockage degree information of the wastewater electromagnetic valve according to the Langerial saturation index.
Specifically, the data processing host computer carries out analysis and calculation according to the received water quality operation parameters, directly carries out matching analysis on the langelier saturation index and a preset database after obtaining the langelier saturation index of the water quality in the water purifier, directly obtains the water quality scaling capacity at the moment, whether the wastewater electromagnetic valve is blocked or not and the degree of blocking the wastewater electromagnetic valve, and then directly pushes and informs a user so that the user can conveniently process according to the obtained analysis result.
It should be noted that the manner in which the data processing host pushes the information of the water quality scaling capability and the clogging degree of the waste water solenoid valve is not exclusive. In one embodiment, a display is arranged on the surface of the shell of the water purifier, and after the data processing host analyzes the water quality scaling capacity and the blocking degree information of the wastewater electromagnetic valve, the information is transmitted to the display to be displayed, and a user can directly observe the information when approaching the water purifier. In another embodiment, the data processing host of the water purifier can be in communication connection with an external terminal device, after the data processing host analyzes and obtains the water quality scaling capacity and the blockage degree information of the wastewater electromagnetic valve, the information is transmitted to the external terminal device for storage and display, and a user can obtain corresponding information without approaching the water purifier. It is understood that the type of the external terminal device may be a terminal device with a display function, such as a mobile phone, a tablet, or a computer. Further, in other embodiments, can also adopt the mode of voice push to report the quality of water scale deposit ability and the waste water solenoid valve degree of blockking up information of purifier, as long as can in time inform the user all can.
Through the scheme, the user can know the water quality scaling capacity and the blocking degree information of the wastewater electromagnetic valve of the water purifier in real time in the running process of the water purifier, so that the user can timely process the water quality scaling capacity or the blocking degree of the wastewater electromagnetic valve when exceeding the maximum bearing value of the water purifier or the preset threshold value of the user. Thereby can avoid unified waste water to move under the condition effectively, the condition that the waste water solenoid valve of purifier blockked up easily takes place, strengthens the life of purifier effectively, can also alleviate the condition that reverse osmosis membrane pollutes the jam in the purifier simultaneously, has the advantage that the use reliability is strong.
Referring to fig. 2, in an embodiment, after step S300, the method further includes step S400.
And S400, acquiring the geographical position information of the water purifier, and sending the geographical position information, the water quality scaling capacity and the blocking degree information of the wastewater electromagnetic valve to an external server.
Specifically, the geographical position information, the water quality scaling capability and the blockage degree information of the wastewater electromagnetic valve are used for constructing a water quality map and/or updating the water quality map by an external server. The water quality map is an information database which is formed by water quality scaling capacities corresponding to raw water in different geographical positions and information of blocking degree of a wastewater electromagnetic valve. The water quality of different geographical positions can be rapidly known through the database, so that subsequent operations such as installation of the water purifier and product development are facilitated. It can be understood that, in another embodiment, the water quality map further includes season information and/or weather information, etc., that is, the water quality scaling capability and the information of the degree of causing the blockage of the wastewater solenoid valve at the same geographic location in the water quality map further take into account different seasons and/or different weather information corresponding to the geographic location, so that more accurate water quality scaling capability and information of the degree of causing the blockage of the wastewater solenoid valve can be obtained by combining the geographic location, the season information and the weather information during subsequent water purifier installation or product development.
In this embodiment, each purifier still is provided with the locator, and after the data processing host computer of purifier obtained the quality of water scale deposit ability and the jam degree information of waste water solenoid valve of this purifier, still can obtain the geographical position information that this purifier is located simultaneously according to the locator, then simultaneously with quality of water scale deposit ability, the jam degree information of waste water solenoid valve that correspond to geographical position information send external server to handle. If the water quality scaling capability and the blocking degree information of the wastewater electromagnetic valve at the geographic position are not stored in the external server, the external server adds the information in a corresponding database according to the geographic position information, the corresponding water quality scaling capability and the blocking degree information of the wastewater electromagnetic valve, and then the water quality map is constructed. If the external server stores the water quality scaling capacity and the blocking degree information of the wastewater electromagnetic valve at the geographic position, the external server replaces the water quality map in a corresponding database according to the geographic position information, the corresponding water quality scaling capacity and the corresponding blocking degree information of the wastewater electromagnetic valve, and the water quality map is updated.
Referring to fig. 3, in an embodiment, the langelier saturation index includes a raw langelier saturation index and a concentrated langelier saturation index, and the step of obtaining the water quality scaling capability of the water purifier and the clogging degree information of the waste water solenoid valve according to the langelier saturation index includes a step S310 and a step S320.
And S310, analyzing according to the raw water Langerial saturation index and a preset scaling database to obtain the water quality scaling capacity of the water purifier.
Specifically, the preset scaling database stores the water scaling capacity conditions corresponding to different raw water langelier saturation indexes. The raw water langelier saturation index is the langelier saturation index of the raw water, i.e. the water which is conveyed from an external water source into the water purifier and is not subjected to purification treatment such as filtration. After the data processing host receives the raw water Langerial saturation index, the raw water Langerial saturation index is directly matched with a preset scaling database, and therefore the scaling capacity of the raw water in the water purifier is visually obtained. It can be understood that the number of the preset raw water LSIs in the preset scaling database is not unique, every two adjacent preset raw water LSIs form an interval, and when the analyzed raw water LSIs are located in different intervals, the data processing host correspondingly outputs the scaling degree of the water quality to inform a user through a terminal device or a display arranged on the water purifier. For example, in one embodiment, the preset fouling database is as shown in the following table:
| LSI | 0 | 0.2 | 0.5 | 1.0 | 2.0 | 3.0 |
| degree of fouling | Stable water | Slightly less | Medium and high grade | Severe severity of disease | Is very serious | Is very serious |
As can be seen from the above table, when LSI of raw water is 0. ltoreq. LSI of raw water is less than 0.2, the water is stable water; when the raw water LSI is more than or equal to 0.2 and less than 0.5, the scaling degree is slight; when the raw water LSI is more than or equal to 0.5 and less than 1.0, the scaling degree is moderate; when the raw water LSI is more than or equal to 1.0 and less than 2.0, the scaling degree is serious; when the raw water LSI is more than or equal to 2.0 and less than 3.0, the scaling degree is serious; when LSI is 3.0. ltoreq. raw water, the degree of scaling is very serious.
And S320, analyzing according to the strong water Langerial saturation index and a preset blockage database to obtain the blockage degree information of the wastewater electromagnetic valve of the water purifier.
Specifically, the preset blocking database stores the blocking degree of the wastewater electromagnetic valve corresponding to different concentrated water Langerlies saturation indexes. The concentrated water Langerial saturation index is the Langerial saturation index of the concentrated water, and the concentrated water is water which is discharged after being filtered by a reverse osmosis membrane in the water purifier and has more impurities. After the data processing host receives the strong water Langerial saturation index, the strong water Langerial saturation index is directly matched with a preset blocking database, and therefore the situation that the wastewater electromagnetic valve is blocked under the current state of the water purifier is visually obtained. The larger the value of the concentrated water LSI is, the larger the risk of causing the blockage of the wastewater electromagnetic valve is, and similarly, the number of the preset concentrated water LSIs in the preset blockage database is not unique, and when the concentrated water LSIs obtained by analysis are positioned in different sections, the data processing host correspondingly outputs the information of the degree of the blockage of the wastewater electromagnetic valve, and informs a user through a terminal device or a display arranged on the water purifier.
For example, in one embodiment, the preset clogging database stores therein a first preset concentrate LSI and a second preset concentrate LSI, the first preset concentrate LSI being smaller than the second preset concentrate LSI, indicating that there is no risk of clogging of the wastewater solenoid valve when the concentrate LSI is smaller than the first preset concentrate LSI; when the first preset concentrated water LSI is less than or equal to the concentrated water LSI and less than or equal to the second preset concentrated water LSI, the blocking risk of the wastewater electromagnetic valve is low; when the concentrate LSI is greater than the second preset concentrate LSI, it indicates that there is a greater risk of clogging of the waste water solenoid valve.
Referring to fig. 4, in an embodiment, the water quality operation parameters include water quality data and flow data, and step S200 includes step S210, step S220, and step S230.
And step S210, analyzing according to the water quality data to obtain the raw water Langerial saturation index of the water purifier.
Specifically, referring to fig. 5, in the present embodiment, raw water LSI is converted into a correlation function with water quality data of the water purifier, and the raw water langelier saturation index of the water purifier is finally obtained by analyzing a relationship between F (raw water LSI) and F (hardness, alkalinity, TDS value, pH value, and water temperature), and then the analysis operation of the raw water scaling capacity is directly performed according to the raw water langelier saturation index.
Further, in one embodiment, the water quality data includes at least one of a raw water total dissolved solids value, a raw water hardness, a raw water alkalinity, a raw water temperature, and a raw water hydrogen ion concentration index. In a specific embodiment, the water quality data simultaneously comprises a raw water total dissolved solid value, raw water hardness, raw water alkalinity, raw water temperature and a raw water hydrogen ion concentration index, the corresponding data acquisition device comprises a total dissolved solid probe sensor, a hardness sensor, an alkalinity sensor, a water temperature sensor and a hydrogen ion concentration index sensor, each sensor is respectively arranged at a position corresponding to a reverse osmosis membrane of the water purifier, the raw water is subjected to the acquisition operation of the raw water total dissolved solid value, the raw water hardness, the raw water alkalinity, the raw water temperature and the raw water hydrogen ion concentration index, and the acquired parameters are sent to the data processing host for analysis processing in real time. Specifically, the raw water LSI calculation formula is:
LSIoriginal source＝0.1×log10(TDS)+13.12×log10T+log10H+log10A+PH-44.25
Among them, LSIOriginal sourceThe raw water LSI value is the total dissolved solids value of the raw water, T is the raw water temperature, H is the raw water hardness, A is the raw water alkalinity, and PH is the raw water pH value.
It is understood that in one embodiment, the data processing host has a function of wireless communication with an external terminal device or an external server, and the data processing device further sends the received total dissolved solid value of raw water, hardness of raw water, alkalinity of raw water, temperature of raw water and hydrogen ion concentration index of raw water to the external terminal device, the external server and the like for storage or sends the received total dissolved solid value of raw water, hardness of raw water, alkalinity of raw water, temperature of raw water and hydrogen ion concentration index of raw water to a display for display, so that a user can visually obtain various water quality.
And step S220, analyzing according to the flow data to obtain the recovery rate of the water purifier.
Specifically, referring to fig. 5, the recovery rate is the ratio of pure water to the total water produced in the reverse osmosis water purifier. Raw water in the water purifier is subjected to purification treatment such as reverse osmosis, concentrated water containing more impurities and purified water for drinking can be obtained, and therefore the recovery rate of the water purifier can be directly obtained by analyzing water flow data in different water outlet pipelines.
Further, in one embodiment, the flow data includes concentrate flow data and/or pure water flow data. In a specific embodiment, the flow data includes both the concentrated water flow data and the pure water flow data, and at this time, the concentrated water flow data and the pure water flow data after the purification processing are respectively acquired according to the concentrated water flow sensor and the pure water flow sensor which are arranged in the corresponding branch, and then sent to the data processing host for analysis processing, so that the corresponding recovery rate can be obtained. It should be noted that in one embodiment, X ═ V/(V + U), where X denotes recovery, V denotes net water flow data, and U denotes concentrate water flow data.
And step S230, obtaining the concentrated water Langerial saturation index of the water purifier according to the recovery rate and the raw water Langerial saturation index.
Specifically, referring to fig. 5, after the data processing host analyzes the recovery rate and the raw water LSI, the data processing host further analyzes the data according to a preset functional relation between the concentrated water LSI and the recovery rate and the raw water LSI, and substitutes the obtained raw water LSI and the recovery rate for processing, so as to obtain a final concentrated water LSI value.
In a specific embodiment, the manner of calculation of the dense water LSI is:
LSIconcentration＝2.9×log10n-LSIOriginal source
Among them, LSIOriginal source＝0.1×log10(TDS)+13.12×log10T+log10H+log10A+PH-44.25，LSIConcentrationLSI value of concentrated water, n is recovery rate, LSIOriginal sourceThe raw water LSI value is the total dissolved solids value of the raw water, T is the raw water temperature, H is the raw water hardness, A is the raw water alkalinity, and PH is the raw water pH value.
