[0067] The technical solutions of the present disclosure will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure. In addition, the technical features involved in the different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

[0068] In a relatively closed indoor space such as an office or a bedroom, as the carbon dioxide (CO2) generated by people, pets, plants and the like gradually increases, the air quality will gradually decrease, and long-term stay in the closed space will easily cause human discomfort. Therefore, there is a wide demand for using fresh air equipment to exchange outdoor fresh air with indoor air.

[0069] Common fresh air equipment includes fresh air machines, fresh air air conditioners, etc., for example Figure 1 A fresh air air conditioner is shown in FIG. Figure 1 As shown in FIG. 1, the fresh air air conditioner includes an indoor unit 100 and an outdoor unit 200. The indoor unit 100 is usually hung on the indoor wall, and the outdoor unit 200 is arranged outdoors. The fresh air air conditioner often has a CO2 sensor arranged on the indoor unit 100. The CO2 sensor is used to detect the CO2 concentration in the room, and the current CO2 concentration can be optionally displayed on the display screen 110 of the indoor unit 100 or the remote controller 300. When the detected CO2 concentration exceeds the standard, the fresh air system can be started to exchange the outdoor fresh air with the indoor low-quality air, thereby reducing the indoor CO2 concentration and improving the air quality.

[0070] However, the fresh air air conditioner in the related art is not accurate enough in detecting the indoor CO2 concentration. For example, for an indoor environment with small gas disturbance (e.g., when the fresh air air conditioner is in standby state), the user often subjectively feels that the gas quality has deteriorated, but the detected CO2 concentration by the fresh air air conditioner is still not high. The inventors have found through research that this is because the gas quality of CO2 is greater than that of oxygen. In an indoor scene with no or small gas disturbance for a long time, most of the CO2 will deposit in the middle and lower parts of the indoor space. However, as shown in FIG. Figure 1 The indoor unit 100 of the fresh air air conditioner is often hung on the upper area of the wall, so the CO2 concentration detected by the CO2 sensor arranged on the indoor unit 100 is low, which cannot accurately reflect the current CO2 concentration in the indoor space, affecting the user experience of the fresh air air conditioner.

[0071] Based on the above-mentioned defects in the related art, the embodiments of the present disclosure provide a detection method and device, a fresh air air conditioner and a storage medium, aiming to improve the detection accuracy of the fresh air air conditioner for the concentration of indoor polluted gas such as CO2.

[0072] In a first aspect, the disclosure provides a detection method, which can be applied to a fresh air conditioner. In some embodiments, the detection method of the disclosure can be executed by a processor of the fresh air conditioner.

[0073] As shown in some embodiments, the detection method of the disclosure includes: Figure 2

[0074] S210, obtaining a first detection value of a target sensor of the fresh air conditioner.

[0075] Specifically, the target sensor is a sensor arranged on the fresh air conditioner for detecting the concentration of carbon dioxide in the room.

[0076] For example Figure 1 As shown in the scenario, the target sensor can be a CO2 sensor arranged on the indoor unit 100, so as to detect the CO2 concentration near the indoor unit 100. In some embodiments, the target sensor can be an infrared CO2 sensor, a catalytic CO2 sensor, a thermal conduction CO2 sensor, etc., which is not limited by the disclosure.

[0077] It is worth noting that there can be more than one target sensor arranged on the fresh air system, that is, multiple target sensors can be arranged. For example Figure 1 As shown in the scenario, multiple CO2 sensors are arranged on the indoor unit 100, so as to not affect the detection of the concentration of CO2 when one of the CO2 sensors fails.

[0078] Through the operation of the target sensor, the current CO2 concentration value, that is, the first detection value, can be detected. For example, when the fresh air conditioner includes only one target sensor, the concentration value of CO2 detected by the target sensor is taken as the first detection value. For another example, when the fresh air conditioner includes multiple target sensors, the average value of the detection values of the multiple target sensors can be taken as the first detection value. Those skilled in the art can understand this, and the disclosure will not be repeated.

[0079] It can be understood that the one or more target sensors arranged on the fresh air conditioner always detect the CO2 concentration near the fresh air conditioner. Due to the foregoing reasons, it cannot accurately reflect the actual concentration of CO2 in the entire indoor space, and therefore the first detection value needs to be compensated and corrected.

[0080] S220, obtaining a compensation value of the carbon dioxide concentration determined according to the standby time of the fresh air conditioner when the fresh air conditioner is in a standby state.

[0081] ​Specifically, as known from the foregoing, when the fresh air conditioner is in the standby state, the indoor space gas is not disturbed or is slightly disturbed, and the CO2 gas generated by people, pets, plants and the like in the long-term indoor environment causes the indoor CO2 concentration to increase. That is, the CO2 concentration in the indoor space gradually increases over time.

[0082] In the embodiments of the present disclosure, the compensation value of the CO2 concentration is determined according to the standby time of the fresh air conditioner.

[0083] In one scenario, for example, the fresh air conditioner is just switched from the on state to the standby state for a period of time, the indoor air is in a circulating flow state when the fresh air conditioner is in the on state, and therefore the indoor CO2 deposition phenomenon is slight when the fresh air conditioner is just in the standby state for a period of time, and the determined compensation value is also correspondingly small.

[0084] In another scenario, the fresh air conditioner is in the standby state for a long time, for example, the fresh air system is in the standby state for more than 2 hours, at this time, the indoor air is stationary for a long time, the indoor CO2 deposition phenomenon is serious, and the determined compensation value is also correspondingly large.

[0085] It is worth noting that the obtained compensation value of the CO2 concentration can be a compensation value obtained automatically by the fresh air conditioner according to a preset algorithm, or a compensation value input by a user through a remote controller or a terminal device, for example. The present disclosure does not limit this.

[0086] The specific determination process of the compensation value of the CO2 concentration is described in the embodiments of the present disclosure below, and is not described in detail here.

[0087] S230, compensating the first detection value according to the compensation value to obtain a target detection value.

[0088] Specifically, as known from the foregoing, the first detection value represents the detected concentration value of the CO2 deviating from the fresh air conditioner, and the compensation value is the error value of the actual CO2 concentration determined according to the standby time of the fresh air conditioner, so that the first detection value is compensated and corrected according to the compensation value, and a relatively accurate CO2 concentration value, i.e., a target detection value, is obtained.

[0089] Still taking the fresh air conditioner shown in Figure 1 As an example, the target sensor detects that the CO2 concentration near the indoor unit 100 is a first detection value C1, and the obtained compensation value determined according to the standby time is C0, so that the target detection value C k That is, it can be expressed as:

[0090] C k =C1+C0

[0091] It can be understood that the compensation value C0may be positive or negative, and will not be described here.

[0092] As can be seen from the above, in the embodiments of the present disclosure, the compensation value of the CO2concentration is obtained based on the standby time length, and the first detection value detected by the target sensor is compensated and corrected according to the compensation value, thereby reducing the influence of gas deposition on concentration detection and improving the detection accuracy of the CO2concentration.

[0093] As shown in the foregoing Figure 1 For example, when the fresh air conditioner is turned on, the air in the room exchanges with the outdoor fresh air, and the air in the room is in a high-speed flow state, and there is no gas deposition phenomenon. That is, when the fresh air conditioner is in the on state, it can be considered that the CO2distribution in the room is uniform, and the CO2concentration detected by the target sensor on the indoor unit 100 can accurately represent the actual concentration of the current indoor CO2.

[0094] When the fresh air conditioner has just been turned off for a period of time, for example, the fresh air conditioner has been in standby for about 30 minutes, at this time, although the gas flowability in the room is poor, the CO2deposition phenomenon is relatively weak. The inventors found through multiple simulation simulations that during the period when the fresh air conditioner is in the standby state for a short time, the change rate of the compensation value of the CO2concentration is very low. Therefore, in order to reduce the calculation amount of the compensation value calculation, the compensation value of the fresh air conditioner turned off for a period of time can be preset to a reasonable fixed value.

[0095] When the fresh air conditioner has been turned off for a long period of time, for example, the fresh air conditioner has been in standby for more than 2 hours, at this time, the gas in the room has been stationary for a long time, and the CO2deposition phenomenon is relatively serious. The inventors found through multiple simulation simulations that at this time, the change rate of the compensation value of the CO2concentration changes significantly with the standby time length. Therefore, in the case of long-time standby of the fresh air conditioner, a more reasonable compensation value can be calculated.

[0096] Based on the above principle, Figure 3 Some embodiments of the detection method of the present disclosure are shown in the foregoing Figure 3 will be specifically described below.

[0097] As Figure 3 shown, in some embodiments, the detection method of the present disclosure example includes:

[0098] S310, obtaining the current standby time length of the fresh air conditioner.

[0099] Specifically, the timing can be started when the fresh air conditioner is switched from the on state to the standby state, thereby obtaining the current standby time length.

[0100] Still taking Figure 1For example, the new air conditioner switches from the on state to the standby state at time t1, and thus the current standby duration t0 obtained at the current time t2 can be represented as:

[0101] t0 = t2 - t1

[0102] S320, in response to the current standby duration being not greater than the preset duration threshold, determining the compensation value of the carbon dioxide concentration as a first compensation value.

[0103] It can be understood that the preset duration threshold refers to a threshold value of the degree of change of the aforementioned demarcation compensation value over time, which actually reflects the degree of change of the CO2 gas deposition phenomenon over time.

[0104] For example, when the current standby duration of the new air conditioner is not greater than the preset duration threshold, it indicates that the CO2 gas deposition phenomenon is relatively weak, and the deposition degree changes slightly over time, so it can be approximately considered that the difference between the detection value of the target sensor and the actual CO2 concentration is a constant value. Therefore, in the embodiment of the present disclosure, in this case, the compensation value of the CO2 concentration can be set as a fixed first compensation value.

[0105] It can be understood that the specific value or value range of the preset duration threshold and the first compensation value can be determined in advance according to prior knowledge or a limited number of tests such as simulation, which can be understood and fully implemented by those skilled in the art, and the present disclosure will not be repeated.

[0106] In one example, still taking the aforementioned Figure 1 For example, the preset duration threshold can be set to 1h, and in the case where the current standby duration of the new air conditioner is not greater than 1h, the first compensation value C r1 of the indoor CO2 concentration can be set to 20ppm-30ppm, which belongs to a smaller compensation value range. Thus, the target detection value C k can be represented as:

[0107] C k = C1 + C r1

[0108] Wherein, C1 represents the first detection value detected by the target sensor.

[0109] S330, in response to the current standby duration being greater than the preset duration threshold, determining the compensation value of the carbon dioxide concentration as a second compensation value according to the preset compensation rate, the current standby duration and the first compensation value.

[0110] Similarly, the preset duration threshold refers to a threshold value of the degree of change of the aforementioned demarcation compensation value over time, which actually reflects the degree of change of the CO2 gas deposition phenomenon over time.

[0111] For example, when the current standby time length of the fresh air conditioner is greater than the preset time length threshold, it indicates that the CO2 gas deposition phenomenon is more serious, and the deposition degree changes more obviously with time, so that the second compensation value of the CO2 concentration can be calculated based on the pre-set compensation rate, the current standby time length and the first compensation value.

[0112] In one example, still taking the foregoing Figure 1 scene as an illustration, for example, the preset time length threshold can be set to 1h, in the case where the current standby time length t0 of the fresh air conditioner is not greater than 1h, the first compensation value C r1 of the indoor CO2 concentration can be set to 20ppm-30ppm, which belongs to a smaller compensation value range. When the current standby time length t0 of the fresh air conditioner is greater than 1h, the compensation rate n1 of the indoor CO2 concentration is greater than 1h, and the second compensation value C r2 may be represented as:

[0113] C r2 = n1*t0 + C r1

[0114] Wherein, n1 represents the compensation rate, t0 represents the current standby time length, C r1 represents the first compensation value.

[0115] It can be understood that the specific values or value ranges of the preset time length threshold, the compensation rate and the first compensation value can be determined in advance according to prior knowledge or a limited number of tests such as simulation, and those skilled in the art can understand and fully implement it, and the disclosure will not be repeated.

[0116] Through the foregoing S320 and S330, the detection value of the CO2 gas concentration of the fresh air conditioner in the standby state can be compensated and corrected, thereby reducing the risk of inaccurate detection accuracy caused by gas deposition phenomenon in the standby state, and improving the detection accuracy of the CO2 gas concentration.

[0117] The inventors have also found through multiple simulations that as the current standby time length is prolonged, the gas deposition phenomenon stabilizes, and the concentration of indoor CO2 gradually stabilizes, even if there is no gas disturbance in the room, the concentration of indoor CO2 will not increase, but will fluctuate in a small range.

[0118] Based on this, in some embodiments, the detection method of the disclosure example further comprises:

[0119] In response to the second compensation value being not less than the target compensation value, the target compensation value is determined as the second compensation value.

[0120] Specifically, the target compensation value represents an upper limit of the indoor CO2 concentration compensation value, that is, in S320, as the current standby time t0 increases, the concentration of CO2 will not increase significantly, and thus the second compensation value C r2 will not increase significantly either.

[0121] In this case, the target compensation value can be determined in advance as an upper limit of the CO2 gas concentration compensation value based on prior knowledge or a limited number of experiments such as simulation.

[0122] When the second compensation value calculated in S330 is less than the target compensation value, it indicates that the current indoor CO2 concentration will continue to increase significantly over time, and thus the second compensation value is the actual compensation value.

[0123] When the second compensation value calculated in S330 is not less than the target compensation value, it indicates that the current indoor CO2 concentration has reached the upper limit and will not increase significantly over time, and thus the target compensation value is taken as the second compensation value.

[0124] As can be seen from the above, in the embodiments of the present disclosure, by analyzing the current standby time of the fresh air conditioner, the actual indoor gas change in each time period of the fresh air conditioner standby state can be simulated, so as to accurately reflect the concentration change of CO2 in each stage, and further improve the accuracy of CO2 gas concentration detection.

[0125] It is worth noting that, based on the foregoing, it can be understood that the concentration of indoor CO2 is greatly affected by gas disturbance. For example, compared with a bedroom with closed doors and windows and a bedroom with all doors and windows open, it is obvious that the former has less gas disturbance, while the latter has greater gas disturbance. In the indoor space scenario where all doors and windows are open, for example, the detection compensation of CO2 concentration is also greatly disturbed.

[0126] In this case, in some embodiments of the present disclosure, the fresh air conditioner can be provided with a corresponding "gas concentration compensation switch", and the user can manually turn on or off the detection method of the present disclosure through the switch.

[0127] In one scenario, for example, in the cold winter in the north, when the user sleeps at night, the doors and windows of the bedroom are closed to maintain the indoor heat. In this situation, the gas in the bedroom is kept static for a long time, and there is almost no disturbance of the gas, so that the user can manually turn on the "gas concentration compensation switch" to accurately detect the CO2 concentration in the room. The fresh air conditioner can perform the detection method described above to more accurately detect the CO2 concentration in the bedroom.

[0128] In another scenario, such as a bedroom with doors and windows open for ventilation, good air circulation is maintained while the user sleeps at night, making the CO2 distribution in the bedroom approximately uniform. In this case, the user can manually turn off the "gas concentration compensation switch," and the fresh air conditioner will not perform the aforementioned detection method, directly using the detected CO2 concentration as the actual CO2 concentration in the bedroom.

[0129] by Figure 1 As shown in the example, the "gas concentration compensation switch" in this embodiment can be a button on the remote control 300, which the user presses to turn the switch on / off; it can also be a virtual button or switch on a mobile terminal app, which the user clicks to turn the switch on / off. Of course, the "gas concentration compensation switch" in this embodiment can also be any other suitable switch form, which will not be listed here.

[0130] As can be seen from the above, in this embodiment of the present disclosure, the user can manually turn the detection method of the present disclosure on or off through the gas concentration compensation switch, so as to better detect the indoor CO2 gas concentration for different usage scenarios and improve the user experience.

[0131] It is worth noting that, in the implementation of the above detection method, the compensation value for correcting the first detection value of the target sensor of the fresh air conditioner can be automatically determined by the fresh air conditioner. For example, the processor of the fresh air conditioner can execute the above... Figure 3 The process shown automatically determines the compensation value for CO2 concentration under different current standby times. During this process, the user is completely unaware of it.

[0132] In one example scenario, a user manually turns on the aforementioned gas concentration compensation switch via a mobile app, and then sleeps in the bedroom with the air conditioner in standby mode. At this time, the target sensor on the indoor unit of the air conditioner will detect the first CO2 concentration value in real time, and then automatically execute the aforementioned process to obtain the target detection value, which is then displayed on the display screen of the indoor unit of the air conditioner.

[0133] In other words, the target detection value that the user can see is already the relatively accurate CO2 concentration after system compensation and correction, and the user is unaware of the system's compensation process.

[0134] However, in other implementations, considering that the compensation value for CO2 concentration detection may vary depending on the indoor environment, the compensation value for CO2 concentration detection can also be manually input by the user, that is, the user manually compensates and corrects the indoor CO2 concentration.

[0135] Specifically, in the aforementioned S220, the compensation value obtained by the fresh air conditioner is sent by the mobile terminal.

[0136] In one example, the user sends a compensation value to the fresh air conditioner via a remote control. In another example, the user sends the compensation value to the fresh air conditioner via a smart device such as a smartphone, tablet, or wearable device. It is understood that this disclosure does not limit the form of the mobile device.

[0137] In this embodiment, when a user manually inputs a compensation value, it also needs to be determined based on the aforementioned current standby time, because different standby times correspond to different compensation values. Additionally, the user can also determine the compensation value by considering factors such as room size, window opening status, and number of people; however, these factors are optional rather than mandatory.

[0138] Taking the example of a user sending a compensation value through a mobile app, in order to simplify the user operation, multiple input boxes can be displayed on the mobile phone screen, such as: standby time, room area, number of people, whether the window is open or not. After the user enters the information according to the actual situation, the compensation value can be automatically calculated based on the user's input and a preset algorithm, thus guiding the user to enter the compensation value, which greatly facilitates the user operation.

[0139] It is understood that the above-mentioned automatic compensation and modification of the test results by the fresh air air conditioner and manual compensation and modification of the test results by the user can be implemented either one or a combination of the two, and this disclosure does not impose any restrictions on this.

[0140] As can be seen from the above, in this embodiment of the disclosure, the system can automatically detect and compensate for the CO2 gas concentration, or the user can manually detect and compensate for the current indoor CO2 gas concentration. The user has greater freedom of choice and improves the user experience.

[0141] Reference Figure 1 In the scenario shown, after obtaining the target detection value, the target detection value can be displayed in real time on the display screen 110 of the indoor unit 100, or on the display interface of the mobile terminal or remote control 300. Thus, the user can observe the current CO2 concentration. When the concentration is high, the fresh air system can be manually turned on to exchange the indoor air.

[0142] In some implementations, a preset concentration threshold for indoor CO2 can be set in advance. The target detection value is then compared with the preset concentration threshold. When the target detection value is not less than the preset concentration threshold, the fresh air conditioner can automatically switch from standby mode to on mode, thereby automatically exchanging indoor air for fresh air without manual operation by the user.

[0143] Specifically, in some embodiments, the detection method of the present disclosure example further comprises:

[0144] In response to the target detection value being not less than the preset concentration threshold, switching the fresh air conditioner from the standby state to the open state.

[0145] It can be understood that the preset concentration threshold is a threshold value representing that the indoor CO2 gas concentration exceeds the standard, which is set in advance. When the target detection value obtained after compensation and correction is not less than the preset concentration threshold, it indicates that the actual CO2 concentration in the current indoor environment has exceeded the standard and affects human health, so that the fresh air system can be automatically switched from the standby state to the open state to perform fresh air purification treatment on the indoor air. When the target detection value obtained after compensation and correction is less than the preset concentration threshold, it indicates that the actual CO2 concentration in the current indoor environment has not exceeded the standard, so that the fresh air system remains in the standby state.

[0146] The preset concentration threshold can be obtained according to prior knowledge or a limited number of tests. In one example, taking CO2 as an example, when the concentration of indoor CO2 reaches 800 ppm to 1000 ppm, it will obviously affect the health of indoor human body, so the preset concentration threshold can be set to 800 ppm to 1000 ppm. The person skilled in the art can set the preset concentration threshold according to the specific scene requirement, and the present disclosure does not limit this.

[0147] From the above, in the embodiments of the present disclosure, by comparing the preset concentration threshold with the target detection value, the fresh air system can be automatically started without manual operation of the user, improving the detection accuracy and user experience.

[0148] In addition, the inventors have found that, for example Figure 1 In the prior art fresh air conditioner shown in the prior art, when the fresh air conditioner is switched from long-time standby to open state, the CO2 concentration detected by the CO2 sensor of the indoor unit 100 will suddenly increase, causing the CO2 concentration displayed on the display screen 110 to suddenly increase. For users, the purpose of starting the fresh air system is to reduce the indoor CO2 concentration, so the mutation of the CO2 concentration will greatly reduce the user experience of the fresh air system.

[0149] The inventors have found through further research that the reason for the mutation of the CO2 concentration is that when the fresh air conditioner in the prior art is in a standby state for a long time, the CO2 gradually deposits in the lower part of the room under the condition that the indoor gas is not disturbed or is disturbed to a small extent, and when the fresh air conditioner is switched from the standby state to the on state, the gas flow will drive the CO2 deposited in the lower part to the upper part, resulting in an increase in the CO2 concentration in the upper part of the room. Thus, the CO2 concentration detected by the CO2 sensor on the indoor unit 100 is suddenly mutated from the previous low detection value to a very high detection value, resulting in a mutation of the value displayed on the display screen 110. After the fresh air conditioner works normally for a period of time, the gas in the room flows evenly, and the detection value detected by the CO2 sensor also gradually tends to be stable.

[0150] Based on the defects in the prior art described above, the detection method of the embodiments of the present disclosure further includes a process of correcting the display value of the display screen to avoid mutation of the display value, which will be described in detail below in combination with the embodiments.

[0151] As shown in FIG. 1, Figure 4 the detection method of the embodiments of the present disclosure includes:

[0152] S410, determining a target display value according to a target detection value.

[0153] S420, displaying the target display value on the display interface of the fresh air conditioner and / or the mobile terminal.

[0154] Specifically, the target detection value is the CO2 concentration value obtained by compensating and correcting the first detection value of the target sensor according to the foregoing embodiments. However, in the embodiments of the present disclosure, the target detection value is not necessarily displayed directly on the display interface, but has different display modes for different scenarios, which will be described below.

[0155] In some embodiments, for the case that the fresh air conditioner is in a standby state, the detection method of the present disclosure includes:

[0156] In the case that the fresh air conditioner is in a standby state, the target detection value is determined as the target display value.

[0157] Specifically, as known from the foregoing description, when the fresh air conditioner is in a standby state, the target gas in the indoor gas appears deposition phenomenon, and the target detection value obtained through the detection and compensation process of the foregoing embodiments can relatively accurately reflect the current real CO2 gas concentration in the room.

[0158] Thus, in the case that the fresh air conditioner is in a standby state, the target detection value can be directly determined as the target display value, and the target display value can be displayed on the display interface of the fresh air conditioner and / or the mobile terminal.

[0159] In other implementations, such as Figure 5 As shown, when the fresh air conditioner switches from standby mode to on mode, the detection method of this disclosure example includes:

[0160] S510. When the fresh air conditioner is detected to switch from standby mode to on mode, the target detection value is determined to be the first display value when the fresh air conditioner switches from standby mode to on mode, and the first display value is displayed on the display interface.

[0161] As mentioned above, when the fresh air conditioner switches from standby to on, it circulates indoor air, pushing CO2 gas that has settled in the lower part of the room upwards. This causes a sudden change in the initial detection value of the target sensor located above, leading to a sudden change in the target detection value. If the target detection value is still used as the target display value at this time, the value seen by the user on the display interface will suddenly become larger, affecting the user experience.

[0162] Therefore, in this embodiment of the disclosure, when the fresh air conditioner is detected to be switched to the on state, the target detection value at that moment is first used as the first display value and displayed on the display interface.

[0163] For example Figure 1 In the scenario shown, the fresh air conditioner switches from standby to on state at time t3, allowing the target detection value at time t3 to be obtained using the detection method described in the aforementioned embodiment. Since time t3 is a critical moment, the target detection value is relatively accurate. Therefore, this target detection value at time t3 is determined as the first display value and displayed on the display interface. Thus, the user can observe the first display value that relatively accurately reflects the indoor CO2 gas concentration through the display interface.

[0164] S520: Obtain the second detection value of the target sensor when the fresh air conditioner is turned on.

[0165] Specifically, after the fresh air conditioning is switched on, the indoor air begins to flow, gradually changing from a settled state to a uniformly distributed state. During this process, the target sensor can detect the CO2 concentration in real time, which is the second detection value.

[0166] Meanwhile, during this process, the display interface continues to show the first display value from S510. In other words, the second detection value detected during this process is no longer displayed on the interface.

[0167] Still with Figure 1 Taking a scenario as an example, after the air conditioner switches from standby to on, the CO2 in the indoor air undergoes the following process changes: it is deposited in the lower part of the room, driven to the upper part of the room, and then evenly distributed throughout the room.

[0168] During the whole change process, the CO2 sensor arranged on the indoor unit 100 detects the CO2 concentration in real time, that is, the second detection value is detected. However, the first display value is always displayed on the display interface at this time.

[0169] S530, in response to the change rate of the second detection value meeting the preset condition, determining the second detection value as the target display value.

[0170] Specifically, as known from the foregoing, the stages of indoor gas flow include: deposition in the lower part of the room - being driven to the upper part of the room - uniform distribution in the whole room.

[0171] Therefore, after the sudden increase of the second detection value detected by the target sensor, the second detection value should gradually decrease (the CO2 gas distribution gradually becomes uniform), and therefore the change rate of the second detection value gradually tends to be stable over time, that is, the change rate gradually decreases.

[0172] In some embodiments, a preset rate threshold of the change of the second detection value can be set in advance, and when the change rate of the second detection value is not greater than the preset rate threshold, it can be determined that the change rate of the second detection value meets the preset condition. The following embodiments of the present disclosure are described, which are not described here.

[0173] When the change rate of the second detection value meets the preset condition, it indicates that the CO2 gas in the room gradually tends to be uniformly distributed, that is, the detection value of the target sensor can represent the actual concentration of the CO2 gas, and therefore the second detection value can be determined as the target display value.

[0174] It is worth noting that in the process of S530, the first display value in S510 is still displayed on the display interface.

[0175] S540, updating the first display value on the display interface to the target display value.

[0176] Specifically, in S520-S530, the first display value determined in S510 is always displayed on the display interface, and the target display value obtained in S530 represents the detection value of the CO2 gas after uniform distribution, and therefore the first display value can be updated by using the target display value.

[0177] It can be understood that since the target display value is the detection concentration of the CO2 after tending to be uniformly distributed, the target display value will not have a large range of mutation compared with the first display value, and therefore updating the first display value by using the target display value can not only ensure that the display value on the display interface is the real concentration detected by the sensor, but also can prevent a large range of mutation of the numerical value on the display interface, thereby improving the user experience.

[0178] In addition, it is worth noting that the first display value in the embodiment of the present disclosure is determined based on the target detection value after compensation correction, that is, the first display value itself is closer to the real concentration of CO2 gas in the room at the opening time of the fresh air conditioner than the prior art, and the display value is not low due to the deposition phenomenon in the prior art, thereby further reducing the risk of sudden increase of the display value.

[0179] As shown in Figure 6 In some embodiments, the detection method of the present disclosure determines the process of determining that the change rate of the second detection value meets the preset condition, including:

[0180] S610, obtaining the change rate of the second detection value in a plurality of continuous sampling periods.

[0181] S620, in response to the change rate of the second detection value in the continuous preset number of sampling periods being not greater than the preset rate threshold, determining that the change rate of the second detection value meets the preset condition.

[0182] Specifically, the sampling period is the sampling point interval determined according to the sampling frequency of the target sensor. In one example, the sampling frequency of the target sensor is 100Hz, and the sampling period is 10ms, that is, detection is performed once every 10ms.

[0183] According to the detection of the target sensor, the second detection value detected in each sampling period can be obtained, so that the change rate of the second detection value can be determined according to the change of the second detection value of the adjacent two sampling periods and the sampling period length.

[0184] Based on the foregoing, the change rate of the second detection value indicates the speed of the sudden increase of the CO2 gas concentration gradually tending to be stable. When the change rate of the second detection value gradually decreases, it indicates that the distribution of CO2 gas in the room is gradually uniform.

[0185] Therefore, in the embodiment of the present disclosure, the preset rate threshold can be determined in advance according to prior knowledge or a limited number of tests such as simulation, and the preset rate threshold represents a threshold value of uniform distribution of CO2 gas in the room.

[0186] When the change rate of the second detection value in the continuous preset number of sampling periods is not greater than the preset rate threshold, it indicates that the CO2 gas in the room has been uniformly distributed, and the detection value of the target sensor at this time can truly reflect the current CO2 gas concentration in the room. For example, in the CO2 detection scenario in Figure 1 When the CO2 sensor detects that the change rate of the second detection value in the continuous 60 sampling periods is not greater than the preset rate threshold, it indicates that the CO2 in the room is uniformly distributed.

[0187] When the change rate of the second detection value is greater than the preset rate threshold in a continuous preset number of sampling periods, it indicates that the CO2 gas in the room is still in the process of being driven to the upper part of the room and uniformly distributed in the entire room, and the detection value of the target sensor still has a large fluctuation, and the first display value on the display interface is continuously maintained.

[0188] In some embodiments, in the process of updating the first display value on the display interface to the target display value, in order to further avoid the bad experience caused by the sudden change of the value to the user, the first display value can be gradually changed to the target display value at a preset rate.

[0189] Specifically, in some embodiments, the process of updating the first display value on the display interface to the target display value can include:

[0190] The first display value on the display interface is changed to the target display value at a preset first change rate.

[0191] It can be understood that the first change rate is the rate of change of the preset value, which can be set in advance according to prior knowledge. For example, assuming that the first display value is 900 ppm and the target display value is 800 ppm, the first change rate can be preset to 200 ppm / s, so that the first display value 900 ppm on the display interface can be gradually reduced to the target display value 800 ppm in 0.5 s, thereby avoiding the sudden change of the value and reducing the user experience.

[0192] It is worth noting that in the above embodiments, the display interface can be a display screen provided on the fresh air conditioner, for example Figure 1 the display screen provided on the indoor unit 100 in FIG. 1. It can also be a display screen provided on a mobile terminal, for example Figure 1 the display screen provided on the remote controller 300 in FIG. 2, or the display screen provided on a smart phone, a tablet computer, a wearable device, etc.

[0193] Therefore, the target display value can be displayed on the display screen of the indoor unit, or on the display screen of the remote controller, the smart phone, the tablet computer, the wearable device, etc., for the user to observe.

[0194] As can be seen from the above, the detection method of the embodiments of the present disclosure updates the first display value with the target display value after the CO2 gas tends to be uniformly distributed in the process of switching the fresh air conditioner from the standby state to the on state. The display value on the display interface is ensured to be the real concentration detected by the sensor, and the value on the display interface will not have a large range of sudden change, thereby improving the user experience. At the same time, the first display value is determined based on the target detection value after compensation and correction, which further reduces the risk of sudden increase of the display value.

[0198] The compensation module 703 is configured to compensate the first detection value according to the compensation value to obtain a target detection value.

[0199] As described above, in the embodiments of the disclosure, the compensation value of the CO2 concentration is acquired based on the standby duration, and the first detection value detected by the target sensor is compensated and corrected according to the compensation value, so as to reduce the influence of the gas deposition phenomenon on the concentration detection and improve the detection accuracy of the CO2 concentration.

[0208] acquire a second detection value of the target sensor in a case where the fresh air conditioner is in the open state;

[0209] In response to the fact that the rate of change of the second detection value meets the preset condition, the second detection value is determined to be the target display value;

[0210] The first displayed value on the display interface will be updated to the target displayed value.

[0211] In some implementations, the display module is specifically configured as follows:

[0212] Obtain the rate of change of the second detection value over multiple consecutive sampling periods;

[0213] If the rate of change of the second detection value does not exceed a preset rate threshold within a continuous preset number of sampling periods, it is determined that the rate of change of the second detection value meets the preset condition.

[0214] In some implementations, the display module is specifically configured as follows:

[0215] According to the preset first rate of change, the first displayed value on the display interface will be changed to the target displayed value.
