Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the disclosure provides a method for detecting the identity of a filter screen, which is applied to an air conditioner with an IFD dust removal function. As shown in fig. 1, the method for detecting the identity of the filter screen performed by the air conditioner includes the following steps:
s101, receiving password verification information of the filter screen, wherein the password verification information is obtained through a password label attached to the filter screen;
s102, determining the authenticity of the filter screen based on the password verification information.
The method for detecting the identity of the filter screen is applied to the scene of replacing the filter screen of the air conditioner. For example, the filter screen is replaced after the filter screen is damaged, the filter screen is replaced after dust blocks the filter screen, or the filter screen is replaced after the service life of the filter screen reaches a service life limit threshold. In this disclosed embodiment, the identity of filter screen is detected to the password authentication information that the air conditioner accessible was received, and then can reduce the condition that leads to connecting the power of filter screen and take place to damage because of changing the imitative article filter screen through the discernment of identity, can improve user experience and feel.
The air conditioner has an IFD dust removal function. When the IFD dust removal function of the air conditioner is started, the filter screen can adsorb dust, PM2.5 and other pollution particles in the air. Namely, the filter screen can be a filter screen for IFD dust removal.
In the embodiment of the disclosure, the air conditioner may be in communication connection with the terminal device and the server, respectively. The communication connection may include: a bluetooth Communication connection, a WIreless-Fidelity (Wi-Fi) Communication connection, a second Generation Mobile Communication Technology (2G) Communication connection, a 3G Communication connection, a 4G Communication connection, and a 5G Communication connection, which are not limited in the embodiments of the present disclosure.
The above-mentioned password authentication information who receives the filter screen includes: and receiving the password authentication information sent by the terminal equipment or receiving the password authentication information sent by the server.
Here, the terminal device may include a mobile terminal or a wearable electronic device. The mobile terminal includes: a notebook, tablet, or cell phone, etc.; the wearable electronic device includes: smart bracelet or smart watch, etc., this disclosed embodiment does not make the restriction.
In the embodiment of the disclosure, the filter screen is attached with the password label. The password label is provided with a bar code, and the bar code can comprise: one-dimensional bar codes or two-dimensional bar codes, embodiments of the present disclosure are not limited.
The password authentication information is obtained through a password label attached to the filter screen. The password information of the filter screen can be obtained by scanning the bar code on the password label. That is, the password authentication information may be obtained by authenticating the password information of the filter.
The password authentication information is used for determining the identity of the filter screen. In an embodiment of the present disclosure, the password authentication information may include: and (5) password verification results. Determining the identity of the filter screen based on the password authentication information includes: when the password verification result shows that the password verification fails, determining the identity of the filter screen as a counterfeit product; and when the password verification result shows that the password verification is successful, determining the identity of the filter screen as a genuine product.
In the embodiment of the disclosure, the IFD dust removal function may be turned on when it is determined that the identity of the filter screen is genuine and the filter screen is installed in the air conditioner. When the identity of the filter screen is determined to be a counterfeit, the IFD dust removal function can be refused to be started.
As shown in fig. 2, in order to detect the identity of the filter, a security chip 20 is typically mounted on the filter. The anti-counterfeiting chip 20 is connected with a main board 40 of an air-conditioning indoor unit of an air conditioner through a connecting wire 30. The Micro Control Unit (MCU) on the main board 40 obtains the encrypted password of the filter screen by communicating with the anti-counterfeit chip 20, thereby realizing the identification of the filter screen. However, the installation of the counterfeit-proof chip 20 for identification has a problem of high detection cost.
In view of the above, the embodiments of the present disclosure provide that the identity of the filter screen is determined based on password authentication information by receiving the password authentication information of the filter screen. That is to say, this disclosed embodiment only can confirm the filter screen identity through software identification, and need not increase extra anti-fake chip and connecting wire, not only can reduce the detection cost can also increase the reliability that filter screen identity detected.
In some embodiments, the method further comprises:
recalculating the life of the filter screen when the identity of the filter screen is determined to be genuine;
refusing to start the IFD dust removal function of the air conditioner when the identity of the filter screen is determined to be a counterfeit product;
and after the identity of the filter screen is determined to be a genuine product, the password information carried by the password label is invalid.
In the embodiment of the disclosure, after the identity of the filter screen is determined to be a genuine product, the password information carried by the password tag is invalid. That is to say, the password label is a one-time password label, the barcode on the password label can be scanned only once, and password information carried by the barcode on the password label will be invalid after the barcode is scanned once. Namely, the air conditioner can only receive password verification information for determining the identity of the filter screen as a genuine product once, and the password verification information for determining the identity of the filter screen as the genuine product cannot be obtained by rescanning the password label in the process of installing the filter screen or the process of operating the air conditioner.
Here, when the identity of the screen is determined to be genuine, the life of the screen is recalculated. That is to say, the life-span of filter screen just recalculated for the genuine article through the identity that the code label detected the filter screen in the change filter screen scene, and the life-span of filter screen can not recalculated in installation filter screen in-process or air conditioner operation in-process rescan code label. The service life of the filter screen is calculated only by being related to the service condition of the filter screen, so that the uniqueness of the service life calculation of the filter screen can be ensured, and the service life calculation of the filter screen is more accurate.
Here, when the identity of the filter screen is determined to be a counterfeit, the filter screen of the counterfeit may cause the power supply connected with the filter screen to be damaged, and the use experience of the IFD dust removal function is affected. Therefore, the air conditioner refuses to open the IFD dust removal function when the identity of the filter screen is determined to be the imitation, the dust removal effect of the air conditioner can be improved through the filter screen using the genuine product, the user experience is improved, the condition that the power supply connected with the filter screen is damaged can be reduced, and the air conditioner can be used more safely and reliably.
In the embodiment of the disclosure, since the filter screen of the imitation does not affect the use of other functions in the air conditioner except the IFD dust removal function, when the identity of the filter screen is determined to be the imitation, the other functions of the air conditioner can be normally used. Wherein the other functions may include: a dehumidification function, a heating function, or a cooling function, which are not limited in the embodiments of the present disclosure.
In some embodiments, the method further comprises:
acquiring accumulated counts corresponding to different gear rotating speeds when a fan in the air conditioner operates at the different gear rotating speeds from a preset accumulation memory;
and determining the service life of the filter screen based on the accumulated count and the interval duration corresponding to different gear rotating speeds.
In the embodiment of the disclosure, the accumulation memory may be a charged erasable programmable read only memory.
Here, the accumulated counts corresponding to different gear speeds are stored in different storage areas of the preset accumulated count memory. When the service life of the filter screen is calculated, the air conditioner can directly acquire the accumulated count from the accumulation memory to determine the service life of the filter screen, so that the service life of the filter screen is simpler to count.
In the embodiment of the disclosure, the air conditioner stores the interval duration corresponding to the rotating speeds of different gears in advance. The interval duration corresponding to the different gear rotating speeds is different, and the interval duration corresponding to the different gear rotating speeds can be set according to the different gear rotating speeds.
In some embodiments, the gear speed is inversely related to the interval duration corresponding to the gear speed.
For example, the air conditioner has a 5-gear rotating speed, the rotating speeds of different gears are increased along with the increasing of the gears, the rotating speed of the 1 gear is the smallest, and the rotating speed of the 5 gear is the highest. When the interval duration corresponding to different gear rotation speeds is set, the interval duration corresponding to the 1-gear rotation speed is set to be 100 minutes, the interval duration corresponding to the 2-gear rotation speed is set to be 90 minutes, the interval duration corresponding to the 3-gear rotation speed is set to be 80 minutes, the interval duration corresponding to the 4-gear rotation speed is set to be 70 minutes, and the interval duration corresponding to the 5-gear rotation speed is set to be 60 minutes. In some embodiments, said determining a life of said strainer based on said accumulated count and a duration of an interval corresponding to different said gear speeds comprises:
obtaining the service time of the filter screen corresponding to different gear rotating speeds based on the product of the accumulated count corresponding to each gear rotating speed in different gear rotating speeds and the interval duration corresponding to each gear rotating speed;
summing the service time of the filter screen corresponding to different gear rotating speeds, and determining the service life of the filter screen.
The accumulated counts corresponding to different gear rotating speeds are related to the service time of different gear rotating speeds in the air conditioner fan, the accumulated counts corresponding to the different gear rotating speeds can be the same or different, and the embodiment of the disclosure is not limited.
In the disclosed embodiment, the air conditioner may include a first gear rotation speed, a second gear rotation speed, and a third gear rotation speed. Obtaining the service time of the filter screen corresponding to the rotating speeds of different gears can include: obtaining the service time of the filter screen corresponding to the first gear rotating speed based on the product of the accumulated count corresponding to the first gear rotating speed and the interval duration corresponding to the first gear rotating speed; obtaining the service time of the filter screen corresponding to the second gear rotating speed based on the accumulated count corresponding to the second gear rotating speed and the interval duration corresponding to the second gear rotating speed; and obtaining the service time of the filter screen corresponding to the second gear rotating speed based on the accumulated count corresponding to the third gear rotating speed and the interval duration corresponding to the third gear rotating speed.
It should be noted that the life of the filter screen may be the remaining life of the filter screen. The above-mentioned filter screen live time to different gear rotational speeds correspond sums, confirms the life-span of filter screen can include: summing the service time of the filter screens corresponding to the rotating speeds of different gears to obtain the total service time; and obtaining the service life of the filter screen based on the difference between the service life limit threshold value of the filter screen and the total service life.
Here, when the live time of filter screen reaches life-span limit threshold value, the filter screen can take place ageing or the pollution granule can block up the filter screen, and then makes the IFD dust removal effect of filter screen can worsen. To this, this disclosed embodiment can not influence the use of IFD dust removal function by changing the filter screen when reaching the life-span limit threshold value of filter screen through calculating the life-span of filter screen.
In some embodiments, the method further comprises:
when the IFD dust removal function of the air conditioner is started, the running time of the fan running at different gear rotating speeds is obtained;
determining the accumulated counts corresponding to different gear speeds based on the running time;
respectively storing the accumulated counts corresponding to different gear rotating speeds in different storage areas to obtain the preset accumulated memory; wherein a storage space occupied by storing the accumulated count is smaller than a storage space occupied by storing the operation time.
In the embodiment of the disclosure, the filter screen is used only when the IFD dust removal function is started. The embodiment of the disclosure determines the accumulation count based on the running time acquired when the IFD dust removal function is started, so that the accumulation count can accurately reflect the service condition of the filter screen, and further more accurate service life of the filter screen can be obtained based on the accumulation count.
In the process of acquiring the running time, the air conditioner can acquire the running time at different gear rotating speeds through the timer. For example, when the IFD dust removal function is turned on and it is detected that the fan of the air conditioner is operating at the first gear speed, the timer corresponding to the first gear speed starts timing until the fan is operating at a speed other than the first gear speed or the IFD dust removal function is turned off. And at the moment, the timing data on the counter is the running time of the fan running at the first gear rotating speed. By analogy, the running time of the fan running at different gear rotating speeds can be obtained.
The accumulated counts corresponding to the rotating speeds of different gears are respectively stored in different storage areas, so that the accumulated counts can be directly obtained from the different storage areas of the accumulation memory when the service life of the filter screen is calculated.
For example, the air conditioner has a 5-speed rotation speed, and the accumulation memory has 5 different storage areas, which are a storage area corresponding to the 1-speed rotation speed, a storage area corresponding to the 2-speed rotation speed, a storage area corresponding to the 3-speed rotation speed, a storage area corresponding to the 4-speed rotation speed, and a storage area corresponding to the 5-speed rotation speed. Wherein, the accumulation count 10 corresponding to the 1 st gear rotating speed is stored in the storage area corresponding to the 1 st gear rotating speed; the storage area corresponding to the 2 nd gear rotation speed stores the accumulated count 20 corresponding to the 2 nd gear rotation speed, which is not limited in the embodiment of the disclosure.
Here, since the storage space occupied by the storage accumulation count is smaller than the storage space occupied by the storage operation time, compared with the total operation time of storing the rotation speeds corresponding to different gears when the service life of the filter screen is calculated, the memory space required by calculating the service life of the filter screen can be reduced by the storage accumulation count in the embodiment of the disclosure, more memory resources can be saved for the air conditioner, and the utilization rate of the memory resources can be improved.
In some embodiments, the method further comprises:
and when the service life of the filter screen is recalculated, clearing the accumulated counts stored in different storage areas.
In the embodiment of the disclosure, the air conditioner recalculates the service life of the filter screen when the identity of the filter screen is determined to be a genuine product based on the received password verification information. That is to say, the embodiment of the present disclosure clears the accumulated counts in different storage areas only when the identity of the filter screen is determined to be a genuine product, and restarts to accumulate in different storage areas when the IFD dust removal function of the air conditioner is turned on after the accumulated counts are cleared, instead of accumulating on the basis of the historical counts.
