The embodiments of the present invention can be described with respect to any air purifier, since they are based on the same implementation principle.
In one embodiment of the invention, the air purifier may be connected to the server platform via an intelligent internet of things WiFi module. For example, can be at this intelligence thing of air purifier's casing internal surface mounting and ally oneself with wiFi module to be connected air purifier and intelligence thing and ally oneself with wiFi module through serial ports communication connecting wire.
In detail, whether the existence of intelligence thing antithetical couplet wiFi module can not influence air purifier's normal work, and air purifier exists independently promptly.
In detail, the server platform and the intelligent internet of things WiFi module, and the intelligent terminal can perform information interaction based on xmpp.
In one embodiment of the present invention, the relevant operating state parameters of the air purifier may include: the air purifier comprises any one or more of an operating mode of the air purifier, wind speed, ambient air quality, actual accumulated service time of an internally installed filter screen and filter screen codes. Of course, in other embodiments of the present invention, the method may further include: the product serial number, the timing time, the standard service life of the filter screen and the like of the air purifier.
In detail, the working mode can be three categories of high-grade, normal and sleep; the wind speed can be three types of high speed, medium speed and low speed; the quality of the ambient air can be four types of excellent, good, medium and poor; the actual accumulated service time of the filter screen can be the accumulated service time of the normal work of the air purifier; the filter screen code can be a code, a two-dimensional code or a bar code which is formed by numbers and capital letters according to a certain coding rule, and at least can contain information of a manufacturer, production time, production number, recommended matched air purifier type and the like of the filter screen; the product serial number of the air purifier can be a code, a two-dimensional code or a bar code which is formed by numbers and capital letters according to a certain coding rule, and at least can contain information such as manufacturers, production time, production numbers, machine types and the like; the timing time can be preset fixed time for opening and closing the air purifier; the standard service life of the filter screen can be the preferred service life obtained by a filter screen manufacturer through a service life test, such as 1200h, 1500h and the like.
In detail, for the obtaining mode of the relevant operation state parameters of the air purifier, at least the following two implementation modes can be provided:
mode A: actively acquiring;
mode B: and (4) passive receiving.
Corresponding to the mode a, in an embodiment of the present invention, the intelligent internet of things WiFi module may obtain the relevant operating state parameters of the air purifier connected thereto in real time or periodically, and send the relevant operating state parameters to the server platform.
In the mode a, the recording mode of the actual accumulated use time of the filter screen can be realized by at least two modes:
mode a 1: recording by the air purifier;
mode a 2: and recording by the server platform.
In detail, corresponding to the above-mentioned manner a1, a timer may be included in the air purifier for recording the actual cumulative use time of the air purifier in real time, which may also be the actual cumulative use time of the filter screen. The actual accumulated use time can be included in the relevant operation state parameters acquired by the intelligent internet of things WiFi module. After the server platform acquires the relevant running state parameters, the actual accumulated use time included in the relevant running state parameters can be read and compared with a preset time threshold value for judgment.
Thus, in one embodiment of the invention, the relevant operating state parameters include: the actual accumulated service time of the filter screen;
the determining of the accumulated service time of the filter screen comprises the following steps: and determining the accumulated service time of the filter screen as the actual accumulated service time.
Correspondingly, the actual accumulated usage time may also be recorded by the server platform, corresponding to the method a 2. For example, the server platform may determine the actual accumulated usage time according to the relevant operating state parameters acquired in real time. When the air purifier is working, the server platform can acquire relevant running state parameters in real time, so that the actual accumulated service time is recorded in real time, and when the air purifier stops working, the recording is suspended and the recording result is reserved.
Corresponding to the mode B, in an embodiment of the present invention, the main control module in the air purifier may send the relevant operation state parameters to the server platform through the intelligent internet of things WiFi module in real time or periodically.
In the mode B, referring to the above-mentioned mode a1 and mode a2, there may be two recording modes of the actual accumulated usage time of the filter screen, namely, the air purifier record and the server platform record. Since the recording manner may be based on the same implementation principle, the embodiment of the present invention is not described herein again.
Based on the above, when the actual accumulated usage time is recorded by the server platform, it is necessary to ensure that the information communication between the server platform and the air purifier is uninterrupted. Thus, in one embodiment of the present invention, it is possible to monitor whether normal information communication can be maintained between the two by means of heartbeat messages.
For example, the intelligent internet of things WiFi module sends a heartbeat message with a fixed format to the server platform every 25 seconds, and the server platform can return a heartbeat message to the intelligent internet of things WiFi module after receiving the heartbeat message. If there is a heartbeat between intelligence thing networking wiFi module and the server platform, then the server platform can regard air purifier as online.
In an embodiment of the present invention, the determining the time threshold includes: determining a time threshold according to the following formula (1);
Tt＝k×T0(1)
wherein, TtFor the time threshold, k is the recommendation coefficient, T0Is the standard service life of the filter screen.
For example, T0At 1200h and k of 0.9, TtThe time is 1080 h.
In detail, the standard service life of the filter screens with different specifications and models can be different and is provided by filter screen manufacturers. The recommended coefficients may be provided by the filter screen manufacturer or may be determined by the user himself.
In detail, the actual accumulated use time records the working duration of the filter screen, but the influence of the use environment of the filter screen on the service life of the filter screen is not considered. In general, within the same working time range, for the same filter screen, the higher the working mode grade of the air purifier is, the higher the wind speed grade is, or the worse the ambient air quality is, the higher the filter screen damage rate is, the shorter the filter screen available time is, and the corresponding filter screen should be replaced as soon as possible. So, can carry out optimization to actual accumulative total service life according to air purifier's concrete behavior to improve the accuracy that the filter screen was changed and is reminded.
Therefore, in order to improve the accuracy of the filter screen replacement prompt, in an embodiment of the present invention, the relevant operating state parameters include: actual accumulated usage time of the filter screen and at least one operating parameter of the air purifier;
the determining the accumulated service time of the filter screen according to the relevant operating state parameters comprises the following steps: and optimizing the actual accumulated service time according to the at least one working parameter to generate an optimized theoretical accumulated service time, and determining that the accumulated service time of the filter screen comprises the theoretical accumulated service time.
Since the relevant operation state parameter includes the actual accumulated usage time, it is described that the actual accumulated usage time is recorded by the air purifier in the embodiment of the present invention. Of course, in another embodiment of the present invention, the server platform may also record the actual accumulated usage time, and optimize the recorded actual accumulated usage time based on at least one operating parameter included in the relevant operating state parameters.
In one embodiment of the present invention, the at least one operating parameter comprises: any one or more of mode, wind speed, ambient air quality.
After the theoretical accumulated use time is calculated, the accumulated use time of the filter screen can be determined as the theoretical accumulated use time, or the theoretical accumulated use time and the actual accumulated use time are included.
As such, in one embodiment of the present invention, the accumulated usage time of the filter screen further includes: the actual accumulated usage time;
when judging that the accumulated service time of the filter screen is not less than the time threshold, the method comprises the following steps: and when the theoretical accumulated use time is judged, and/or the actual accumulated use time is not less than the time threshold value.
In detail, the server platform may determine whether the intelligent terminal needs to be notified based on a comparison between the accumulated usage time of the filter screen and a preset time threshold. In addition, when determining the accumulated service time of the filter screen, the server platform can directly push the accumulated service time of the filter screen to the intelligent terminal no matter whether the preset time threshold value is reached, so that a user can conveniently know and check the accumulated service time of the filter screen.
In an embodiment of the present invention, when a user opens a corresponding dedicated APP (Application) on the intelligent terminal, the intelligent terminal may notify the server platform that the server platform is online, and the server platform may push the determined accumulated usage time of the filter screen, the obtained relevant operating state parameters, and the like to the intelligent terminal, and update an interface of the intelligent terminal.
In an embodiment of the present invention, the optimizing the actual cumulative usage time according to the at least one operating parameter includes: optimizing the actual accumulated use time according to the at least one working parameter by using the following formula (2);
wherein T' is the theoretical accumulated use time, T is the actual accumulated use time, n is the number of the at least one working parameter, m is the number of the types of any one working parameter, kijOptimized parameters, t, for the jth class of the ith operating parameterijThe state duration of the jth class for the ith operating parameter.
For example, assume that the operating parameters of the air purifier include mode, wind speed, and ambient air quality, wherein the operating mode can be three categories, advanced, normal, and sleep; the wind speed can be three types of high speed, medium speed and low speed; the quality of the ambient air can be four types of excellent, good, medium and poor.
When the preset mode is normal and sleep, the corresponding optimization parameters are respectively k11＝0.4、k120; when the wind speed is high speed and normal speed, the corresponding optimization parameters are respectively k21＝0.5、k220; when the quality of the ambient air is good, good and badThe corresponding optimization parameters are respectively k31＝-0.5、k32＝0、k33＝0.6。
Assume that 12:00 begins using the air purifier for the first time; the working parameters of the air purifier are maintained to be normal, normal speed and difference between 12:00 and 13:00, and the time difference is 1 h; the working parameters of the air purifier are maintained to be normal, high-speed and good between 13:00 and 15:00, and the time difference is 2 hours; 15: 00-18: 00, the working parameters of the air purifier are kept to sleep, normal speed and excellent, and the time difference is 3 h.
When the server platform monitors that the working parameters change at 13:00, the theoretical accumulated use time of the air purifier up to 13:00 can be calculated, and thus, the theoretical accumulated use time of the air purifier up to 15:00 and the theoretical accumulated use time of the air purifier up to 18:00 are also calculated.
Based on the above operating parameter variation, the server platform may perform optimization at 13:00, i.e. T ═ T + k11×t11+k12×t12+k21×t21+k22×t22+k31×t31+k32×t32+k33×t331+0.4 × 1+0 × 0+0.5 × 0+0 × 1+ (-0.5) × 0+0 × 0+0.6 × 1 is 2, the actual accumulated use time is 1h, the theoretical accumulated use time is 2h, and optimization is carried out at 15:00, namely T' ═ T + k11×t11+k12×t12+k21×t21+k22×t22+k31×t31+k32×t32+k33×t333+0.4 × 3+0 × 0+0.5 × 2+0 × 1+ (-0.5) × 0+0 × 2+0.6 × 1 is 5.8, the actual accumulated use time is 3h, the theoretical accumulated use time is 5.8h, and the optimization treatment is carried out at 18:00, namely T' ═ T + k11×t11+k12×t12+k21×t21+k22×t22+k31×t31+k32×t32+k33×t336+0.4 × 3+0 × 3+0.5 × 2+0 × 4+ (-0.5) × 3+0 × 2+0.6 × 1 is 7.3, and the actual accumulated use is performed at this timeThe time is 6h, and the theoretical cumulative service time is 7.3 h.
In other embodiments of the present invention, based on the same implementation principle, other similar formulas or optimization processing schemes may also be adopted to optimize the actual accumulated usage time to obtain the theoretical accumulated usage time.
In detail, the accumulated usage time of the filter screen may include an actual accumulated usage time and a theoretical accumulated usage time. When the number of at least one working parameter, the type of each working parameter and each optimization parameter are changed, the condition that the theoretical accumulated service time is not more than the actual accumulated service time at a certain time can also occur. Therefore, through comparison and judgment, the intelligent terminal can be informed when either one of the two is not less than the preset time threshold value or the two is not less than the preset time threshold value.
According to the above content, when the accumulated service time of the filter screen reaches the preset time threshold, the intelligent terminal can remind the user. On the basis, the server platform can also push the acquired relevant running state parameters and the determined accumulated service time of the filter screen to the smart phone in real time, so that the smart phone can be conveniently checked by a user.
Therefore, in an embodiment of the present invention, before the notifying the intelligent terminal, the method further includes: and sending the relevant running state parameters and the accumulated service time of the filter screen to the intelligent terminal.

the method further comprises the following steps: when the current filter screen code is judged to be different from the last acquired filter screen code, determining the positive and false conditions of the current filter screen code by inquiring a preset filter screen code database; and sending the positive false condition to the intelligent terminal.
In detail, the acquired relevant operation state parameters may include a filter screen code of the current filter screen, and when the filter screen codes acquired twice are inconsistent, the filter screen may be considered to have been replaced, so that the positive false condition of the currently used filter screen may be further determined.
The server platform may be pre-established with a filter screen coding database, and the database may include filter screen codes corresponding to all genuine filter screens. After the database is inquired, if the filter screen code of the current filter screen exists in the database, the filter screen code is judged to be a genuine product, otherwise, the filter screen code can be considered to be a fake and fake product. No matter how the query result is, the query result can be pushed to the intelligent terminal so that the user can know and check the query result in time.
Of course, in another embodiment of the present invention, the user may also manually input the filter screen code based on a dedicated APP installed on the intelligent terminal, or scan a two-dimensional code or a barcode corresponding to the filter screen, and the intelligent terminal may send the obtained code information to the server platform and submit a verification application, so that the server platform determines the corresponding true and false conditions.
