Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for air conditioner detection, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
Fig. 1 is a flowchart of an air conditioner detection method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
and step S102, carrying out infrared detection on a filter screen of the air conditioner to obtain a first detection value.
The infrared ray detection principle in the above-mentioned step is that the sensor detects the distance of preceding barrier through the infrared ray of transmission and receipt fixed wavelength, and according to this characteristic, when detecting the change that produces the pollution degree on the filter screen of fixed distance, can influence the infrared ray volume that the sensor received, and then lead to the change of testing result. For example, the more dark contaminants that accumulate on the filter screen, the more infrared it absorbs, resulting in a lower amount of infrared being received by the sensor; the more light-colored contaminants accumulate on the filter screen, the less infrared they absorb, resulting in a greater amount of infrared being received by the sensor.
In an alternative embodiment, after the air conditioner detection device is started, infrared rays with fixed wavelengths can be emitted to a filter screen of the air conditioner through the sensor, and the returned infrared ray quantity is received, wherein the returned infrared ray quantity is the first detection value.
Step S104, obtaining the difference between the first detection value and the initial detection value to obtain a first difference value.
The initial detection value in the above steps may be a detection value obtained by performing infrared detection on the filter screen by research and development personnel in a research and development stage, may also be a detection value obtained by performing infrared detection on the filter screen of the air conditioner through a sensor when the air conditioner is used for the first time, and may also be a detection value obtained by performing infrared detection on the filter screen of the air conditioner through a sensor after the air conditioner is cleaned.
Optionally, when the air conditioner is started, the initial detection value is a detection value obtained by performing infrared detection on the filter screen.
In order to improve the application range of the air conditioner and meet the use requirements of users in different areas, the air conditioner can be used in different areas, and in the embodiment of the invention, a detection value obtained by performing infrared detection on a filter screen of the air conditioner through a sensor when the air conditioner is started can be used as an initial detection value.
In an alternative embodiment, when the contaminant on the filter screen is a dark contaminant, the received first detection value is generally smaller than the initial detection value, and therefore, the first difference value may be obtained by subtracting the initial detection value from the first detection value. Wherein, the color of the dark pollutant is darker than that of the filter screen; wherein the first difference value indicates a degree of contamination of dark contaminants on the filter screen.
In an alternative embodiment, the received first detection value is typically greater than the initial detection value when the contaminant on the filter screen is a light-colored contaminant, and therefore the first difference may be obtained by subtracting the first detection value from the initial detection value. Wherein, the color of the light-colored pollutant is lighter than that of the filter screen; wherein the first difference value represents a degree of contamination of the light-colored contaminants on the filter screen.
By the above, when pollutants are accumulated on the filter screen, no matter the pollutants are dark-color pollutants or light-color pollutants, the higher the pollution degree of the pollutants is, the larger the difference between the received first detection value and the initial detection value is. Therefore, in a further alternative embodiment, after receiving the first detection value, the first difference value may be obtained directly by calculating an absolute value of a difference between the first detection value and the initial detection value without determining whether the contaminant on the filter screen is a light-colored contaminant or a dark-colored contaminant. Wherein the first difference value represents a degree of contamination of contaminants on the filter screen.
And step S106, determining whether to output reminding information or not based on the comparison result of the first difference and the preset value.
Wherein, the reminding information is used for reminding the pollution of the filter screen.
In an alternative embodiment, it may be determined that the reminder is to be output when the first difference is greater than a preset value, and the reminder is not to be output when the first difference is less than the preset value. The reminding information can be in the form of text reminding, picture reminding, video reminding or sound reminding, fault reporting and the like; the reminding information can be output by adopting a display screen or a loudspeaker of the air conditioner, but the air conditioner is not limited to the method, and the reminding information can also be output by communication equipment such as a mobile phone, a tablet, a computer and intelligent wearing.
The preset value may be a fixed value preset at the factory of the air conditioner, or may be set by a user. For example, when the user does not want to frequently clean the filter screen, the preset value can be adjusted to the maximum value which does not affect the operation of the air conditioner and the body health of the user, so that the frequency of outputting the reminding information can be reduced; when the cleanliness requirement of the air conditioner by a user is high, the preset value can be adjusted to be a small value, so that the user can clean the filter screen in time when the air conditioner is polluted.
The comparison result can indicate whether the filter screen needs to be cleaned, and when the comparison result shows that the filter screen needs to be cleaned, reminding information is output; and when the comparison result does not need to clean the filter screen, the reminding information is forbidden to be output. It should be noted that the comparison result may be a comparison result before the filter screen is cleaned, or may be a comparison result after the filter screen is cleaned, and is not limited herein.
According to the embodiment of the invention, after infrared detection is carried out on the filter screen of the air conditioner to obtain the first detection value, the first difference value can be obtained according to the first detection value and the initial detection value, and whether the reminding information is output or not is determined based on the comparison result of the first difference value and the preset value, wherein the reminding information is used for reminding pollution of the filter screen, the pollution intensity of pollutants attached to the filter screen is detected by using the infrared sensor, and the influence of distance, material and pollutant components on the detection result is reduced by detecting the pollution intensity of the filter screen in different states and comparing the difference values. The method has the advantages of accuracy and strong universality. Meanwhile, after the filter screen is cleaned, whether the filter screen is cleaned up or not can be judged according to a comparison result of the first difference value and a preset value, if the filter screen is cleaned up, a user is automatically stopped to be reminded of cleaning up the filter screen, and the situation that the filter screen is cleaned up but reminding information is continuously output to remind the user of cleaning up is avoided; if the filter screen is not cleared up, then automatic recovery reminds the user to clear up the filter screen, make the user can be timely learn whether the filter screen is cleared up to avoid appearing the filter screen and not by the clear up's the condition, solved among the correlation technique air conditioner testing process can't be according to the automatic shutdown of clearance result of filter screen or resume the technical problem who reminds the user to clear up the filter screen.
Optionally, carry out infrared detection to the filter screen of air conditioner, it includes to obtain first detected value: emitting infrared rays with fixed wavelength to the filter screen through the proximity sensor; receiving an infrared signal returned by the filter screen through a proximity sensor; a first detection value is obtained based on the infrared signal.
The proximity sensor in the above step may be an infrared sensor, which is a sensor capable of sensing infrared rays radiated from a target and measuring by using physical properties of the infrared rays.
In an alternative embodiment, infrared rays of a fixed wavelength may be emitted to the filter screen by the infrared ray sensor; then, an infrared ray signal returned by the filter screen is received by the infrared ray sensor, the infrared ray quantity is calculated based on the infrared ray signal, and the determined infrared ray quantity is used as a first detection value.
Optionally, obtaining the first detection value based on the infrared signal includes: acquiring a plurality of detection values acquired at intervals of a preset period; acquiring a maximum value and a minimum value of a plurality of detection values; the average value of the other detection values except the maximum value and the minimum value among the plurality of detection values is obtained, and a first detection value is obtained.
In order to ensure the accuracy of the detected first detection value, the first detection value may be determined by a plurality of detection values that are continuously acquired. On this basis, the collection period of the detection value, that is, the preset period, may be preset, and the period may be a fixed period set when the air conditioner leaves the factory, or may be a period set according to the needs of the user.
In an optional embodiment, a plurality of detection values acquired at preset intervals may be acquired first; and sequentially arranging the detection values according to the sizes, removing the maximum value and the minimum value in the detection values through comparison, acquiring the median value of other detection values, and determining the median value as a first detection value.
Optionally, determining whether to output the reminding information based on the comparison result between the first difference and the preset value includes: comparing the absolute value of the first difference value with a first preset value; if the absolute value of the first difference is larger than or equal to a first preset value, comparing the absolute value of the first difference with a second preset value; if the absolute value of the first difference is larger than or equal to a second preset value, determining to output reminding information; and if the absolute value of the first difference is smaller than the first preset value or the absolute value of the first difference is smaller than the second preset value, determining that the reminding information is forbidden to be output.
The first preset value in the above steps is smaller than the second preset value, and the smaller the preset value is, the lower the pollution degree of the filter screen is, and the cleaner the filter screen is. If the first difference is smaller than the first preset value, the filter screen is determined not to be detected repeatedly within a period of time; if the first difference value is larger than or equal to the first preset value and smaller than the second preset value, the filter screen needs to be detected repeatedly; and if the first difference is larger than or equal to the second preset value, reminding information needs to be output.
In an alternative embodiment, the absolute value of the first difference is compared with a first preset value; if the absolute value of the first difference is smaller than the first preset value, the variation of the first detection value is not large after the air conditioner runs for a period of time, the filter screen is considered to be cleaned by a user before, and the detection step can not be repeated within a period of time, so that the energy loss can be reduced. If the absolute value of the first difference is larger than or equal to a first preset value, continuing to judge; comparing the absolute value of the first difference value with a second preset value; if the absolute value of the first difference is greater than or equal to the second preset value, the variation of the first detection value is large after the air conditioner runs for a period of time, the pollution degree of the filter screen is high, a user needs to clean the filter screen in time, and the output reminding information can be determined; and if the absolute value of the first difference is smaller than the second preset value, repeating the detection step. And when the absolute value of the first difference is detected to be smaller than a first preset value or the absolute value of the first difference is detected to be smaller than a second preset value, the reminding information is determined to be forbidden to be output.
Optionally, when the running time of the air conditioner reaches the preset time, infrared detection is performed on the filter screen to obtain a first detection value.
The preset time in the above steps can be freely set by the user. For example, the preset time may be an accumulated time or a certain time point.
As an alternative embodiment, after the running time of the air conditioner is over a period of time, a filter screen of the air conditioner may be polluted, and therefore, when the running time of the air conditioner reaches a preset time, the air conditioner detection device may be triggered to perform infrared detection on the filter screen to obtain the first detection value.
As another optional implementation manner, the user is generally in a dark state when the air conditioner is in a space for rest, and in order not to affect the normal rest of the user, the infrared detection may be performed on the filter screen to obtain the first detection value when the light intensity of the environment where the air conditioner is located reaches the preset light intensity. Exemplarily, the air conditioner can detect the filter screen in daytime or under the condition that indoor light is bright, and the user is prevented from being disturbed by the fact that reminding information is output when the user has a rest.
Optionally, after determining to output the reminding information, the method further includes: carrying out infrared detection on the filter screen to obtain a second detection value; obtaining the difference between the second detection value and the initial detection value to obtain a second difference value; and determining whether to output reminding information or not based on the comparison result of the second difference value and the preset value, wherein the reminding information is used for reminding the pollution of the filter screen.
The second detection value in the above step may be equal to or less than the first detection value.
As an optional implementation manner, after the output reminding information is determined, infrared detection is continuously performed on the filter screen to obtain a second detection value, a difference between the second detection value and the initial detection value is obtained to obtain a second difference value, and based on a comparison result of the second difference value and a preset value, whether the filter screen is cleaned or not can be judged; if the second difference value is larger than or equal to the preset value, the filter screen is not cleaned or is not cleaned although cleaned, and then the reminding information is determined to be output; and if the second difference value is smaller than the preset value, the filter screen is cleaned, and the reminding information is forbidden to be output. Wherein, the reminding information is used for reminding the pollution of the filter screen.
Optionally, determining whether to output the reminding information based on the comparison result between the second difference and the preset value includes: comparing the absolute value of the second difference value with a third preset value; if the absolute value of the second difference is larger than a third preset value, determining to output reminding information; and if the absolute value of the second difference is less than or equal to a third preset value, determining that the reminding information is forbidden to be output.
In the above steps, after the reminding information is output, whether the reminding information needs to be continuously output can be judged through a third preset value. It should be noted that the first preset value is less than or equal to the third preset value and less than the second preset value.
As an alternative embodiment, the absolute value of the second difference may be compared with a third preset value; if the absolute value of the second difference is larger than a third preset value, the filter screen is not cleaned or cleaned, and then prompt information is determined to be output; and if the absolute value of the second difference value is smaller than or equal to a third preset value, the filter screen is cleaned, and the reminding information is determined to be forbidden to be output.
Optionally, after the reminding information is determined to be prohibited from being output, the running time of the air conditioner is cleared.
The reminding information forbidden to be output in the above step may be that the absolute value of the first difference is smaller than a first preset value, or that the absolute value of the second difference is smaller than or equal to a third preset value when the absolute value of the first difference is smaller than a second preset value.
Generally, when the reminding information is forbidden to be output, the pollution degree of the filter screen is not large, the filter screen of the air conditioner does not need to be detected again in a short time, and the running time of the air conditioner is reset, so that the situation that the filter screen is repeatedly detected due to the fact that the running time of the air conditioner exceeds a preset value can be prevented.
As an optional implementation manner, the operation time of the air conditioner may be cleared when the absolute value of the first difference is smaller than a first preset value.
