DETAILED DESCRIPTION

[0037] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of embodiments do not represent all implementations consistent with the present invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present invention as recited in the appended claims.

[0038] It is noted that all actions for acquiring signals, information, or data in the invention are carried out in accordance with relevant data protection regulations and policies of the country where they are located, and with authorization granted by owners of corresponding apparatuses.

[0039] FIG. 1 is a flowchart illustrating an air conditioner control method according to an embodiment. As illustrated in FIG. 1, the method includes the following blocks.

[0040] At block S10, a detection apparatus group is controlled to be in different detection modes to detect a state of a target object.

[0041] The detection apparatus group includes at least two detection apparatuses installed on an air conditioner, with a predetermined distance between the at least two detection apparatuses, and the detection apparatus group is wired coupled to a microcontroller unit (MCU) of an indoor unit of the air conditioner.

[0042] As shown in FIG. 2, two detection apparatuses such as a detection apparatus A (a radar A 20 in FIG. 2) and a detection apparatus B 21 (a radar B in FIG. 2) may be installed on the indoor unit of the air conditioner 23. These two detection apparatuses are installed at a certain angle to improve a detection range for detecting the target object. As shown in FIG. 3, the detection apparatus A 30 is coupled to the MCU 31 via a communication port 1, the detection apparatus B 32 is coupled to the MCU via a communication port 2. The MCU is also coupled to a WIFI module 33, and the WIFI module may communicate with a cloud.

[0043] In an example, the two detection apparatuses in the at least two detection apparatuses are arranged oppositely. The detection apparatus may be a radar.

[0044] For example, detection surfaces of the two detection apparatuses may be arranged oppositely, and there is an overlapping part between the detection surfaces of the two detection apparatuses. The detection surface refers to a region area that the detection apparatus can perceive, as shown in FIG. 2, the detection surfaces of the two detection apparatuses are fan-shaped. For example, detection directions of the two detection apparatuses may be arranged oppositely, and there is an intersection between the detection directions of the two detection apparatuses. For example, the two detection apparatuses themselves may also be arranged oppositely. A form of arranging the two detection apparatuses oppositely is not limited by the invention.

[0045] In an example, the detection modes include at least two of a first detection mode, a second detection mode, or a third detection mode.

[0046] In an example, the detection apparatus group includes at least two detection apparatuses. In the first detection mode, the at least two detection apparatuses alternately perform detection on the state of the target object.

[0047] In the first detection mode, the at least two detection apparatuses in the detection apparatus group alternately perform detection on the target object using a time division multiplexing manner. Alternatively, performing the detection on the target object may be referred to as static detection, and the static detection has a relatively high sensitivity for detecting the target object. The static detection is configured to detect whether the target object has a micro motion. When a distance between two adjacent target object positions generated by the same target object is greater than a second predetermined distance and less than a first predetermined distance, it is considered that the target object is in the micro motion. Or, when two adjacent poses generated by the same target object are different, it is considered that the target object is in the micro motion. For example, the target object has the micro motion in arms, fingers, a head, feet or other body parts indoors or the target object moves on a sofa, then monitoring may be performed through the first detection mode with the static detection.

[0048] For example, within a single 20 milliseconds time period, the MCU may control the detection apparatus A to turn on and the detection apparatus B to turn off during a first 10 milliseconds time period, such that the detection apparatus A may perform detection on the target object first during the first 10 milliseconds time period. During the last 10 milliseconds time period, the MCU may control the detection apparatus B to turn on and the detection apparatus A to turn off, such that the detection apparatus B may perform detection on the target object during the last 10 milliseconds time period. As such, using every 20 milliseconds as a cycle, the two detection apparatuses alternately perform detection on the target object during each cycle.

[0049] During the static detection, due to the relatively high sensitivity of the at least two detection apparatuses on the air conditioner, at least two detection apparatuses with the same frequency and the same sensitivity may interfere with each other during operation. For example, a detection signal emitted by the detection apparatus A may be detected by the detection apparatus B, which may interfere with determination of the detection apparatus B. Similarly, a detection signal emitted by the detection apparatus B may also be detected by the detection apparatus A, which may interfere with determination of the detection apparatus A. Thus, the state of the target object detected by the at least two detection apparatuses may be inaccurate. On the basis of this, with controlling the at least two detection apparatuses to alternately perform the static detection on the target object, firstly, the detection apparatus has a high detection sensitivity, it may detect a micro change in the state of the target object; secondly, the at least two detection apparatuses alternately performing detection on the target object may expand the detection range; thirdly, a single detection apparatus is activated at the same time, then the single detection apparatus may not be interfered by other turned-off detection apparatuses, and the detected pose of the target object may be more accurate.

[0050] In an example, the detection apparatus group includes at least two detection apparatuses. In the second detection mode, the at least two detection apparatuses simultaneously perform detection on the state of the target object. A sensitivity of the detection apparatus group in the first detection mode is greater than a sensitivity of the detection apparatus group in the second detection mode.

[0051] In the second detection mode, the at least two detection apparatuses in the detection apparatus group simultaneously perform detection on the target object. Simultaneously performing the detection on the target object may be referred to as dynamic detection. A sensitivity of the dynamic detection is relatively low than a sensitivity of the static detection. The dynamic detection is configured to monitor a position of the target object in real time. When the distance between two adjacent target object positions generated by the same target object is greater than the first predetermined distance, it is considered that the target object has dynamic behavior and the target object position is detected. For example, a user is walking indoors, then monitoring may be performed through the dynamic detection.

[0052] During the dynamic detection, due to the relatively low sensitivity of the at least two detection apparatuses, the at least two detection apparatuses has less interference with each other during operation. For example, due to the low sensitivity of the detection apparatus A, it is difficult to detect the detection signal emitted by the detection apparatus B. Similarly, due to the low sensitivity of the detection apparatus B, it is also difficult to detect the detection signal emitted by the detection apparatus A. Therefore, the at least two detection apparatuses may be controlled to simultaneously turn on for dynamic detection of the target object, firstly, the detection sensitivity of the detection apparatus is relatively low, and there is less interference between the at least two detection apparatuses, thus the accuracy of the detected state of the target object is improved; secondly, the at least two detection apparatuses simultaneously detecting the target object may expand the detection range; thirdly, since the dynamic detection involves a significant change in the target object, using the dynamic detection is sufficient to detect the dynamic behavior of the target object.

[0053] In an example, the detection apparatus group includes at least one detection apparatus. In the third detection mode, one detection apparatus performs detection on the state of the target object.

[0054] For example, when a distance between the target object and one target detection apparatus of the at least two detection apparatuses is close, the target detection apparatus may be controlled to perform the detection on the state of the target object, such that other detection apparatuses can pause performing the detection on the state of the target object, thus saving energy consumption.

[0055] The distance between the target object and the detection apparatus may be indicated by a signal strength. The stronger the signal strength of the target object detected by the detection apparatus, the closer the distance between the target object and the detection apparatus. Therefore, a detection apparatus corresponding to a strongest signal strength selected from a plurality of signal strengths may be taken as the target detection apparatus closest to the target object.

[0056] In the third detection mode, the one detection apparatus may perform the detection on the state of the target object at a predetermined duration interval.

[0057] Taking the predetermined duration interval being 10 milliseconds as an example, the target detection apparatus may perform the detection on the state of the target object at a 10 milliseconds interval, without a need to detect the state of the target object in real time, to further save the energy consumption.

[0058] At block S20, control operation of the air conditioner based on the state of the target object.

[0059] In an example, the state of the target object includes presence or absence of the target object, a position of the target object, a dynamic and static state, and a pose of the target object.

[0060] The presence or absence of the target object refers to whether the target object exists indoors.

[0061] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in the presence of the target object indoors; and controlling the air conditioner to turn off in the absence of the target object indoors.

[0062] The position of the target object refers a position of the target object indoors in the presence of the target object, which may be represented by coordinates of the target object indoors or a latitude and a longitude of the target object.

[0063] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in a case where the target object is indoors; and controlling the air conditioner to turn off in a case where the target object is outdoors.

[0064] The dynamic and static state of the target object include a dynamic state and a static state. When the position of the target object changes indoors or the distance between two adjacent positions of the target object is greater than the first predetermined distance, the target object is in the dynamic state. When the position of the target object remains unchanged indoors, or when the distance between two adjacent positions of the target object is greater than the second predetermined distance and less than the second predetermined distance, the target object is in the static state.

[0065] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in a case of the presence of the target object indoors and an indoor target object being in the dynamic state or the static state.

[0066] The pose of the target object includes a change in the pose of the target object indoors.

[0067] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in a case of the presence of the target object indoors and the pose of the target object changing.

[0068] In related arts, a single detection apparatus is configured on the air conditioner to detect a target object indoors. However, the detection range of the single detection apparatus is limited, and targets outside the detection range of the detection apparatus cannot be detected by the detection apparatus, which may result in missed detection of targets. On the basis of this, the at least two detection apparatuses may be configured on the air conditioner to detect the indoor target object, but the at least two detection apparatuses have the relatively high detection sensitivity, especially for static detection of the target object, the at least two detection apparatuses require higher sensitivity. At least two detection apparatuses with the same frequency and the same sensitivity may interfere with each other during operation, resulting in an error in the detected state of the target object. For example, the detection signal emitted by the detection apparatus A may be detected by the detection apparatus B, which may interfere with determination of the detection apparatus B. Similarly, the detection signal emitted by the detection apparatus B may also be detected by the detection apparatus A, which may interfere with determination of the detection apparatus A. Thus, the state of the target object detected by the at least two detection apparatuses may be inaccurate.

[0069] By means of the above technical solution, the detection apparatus group may be controlled to detect the state of the target object in the first detection mode, and the at least two detection apparatuses in the detection apparatus group may alternately detect the target object in the first detection mode. Firstly, the detection apparatus has a high detection sensitivity, it may detect a micro change in the state of the target object. Secondly, taking the at least two detection apparatuses including two detection apparatuses as an example, in a scenario where the two detection apparatuses alternately perform the detection on the state of the target object, although one detection apparatus pauses detection while the other detection apparatus detects, the two detection apparatuses frequently switch back and forth for detection. Therefore, switching back and forth for detection between the two detection apparatuses can also comprehensively detect the target object surrounding the air conditioner and expand the detection range. Thirdly, a single detection apparatus is activated at the same time, then the single detection apparatus may not be interfered by other turned-off detection apparatuses, and the detected pose of the target object may be more accurate.

[0070] The detection apparatus group may also be controlled to detect the state of the target object in the second detection mode. Firstly, in the second detection mode, the at least two detection apparatuses in the detection apparatus group simultaneously perform the detection of the target object, thus the detection range is wider. Secondly, in the second detection mode, the at least two detection apparatuses has the relatively low detection sensitivity, and the interference between the at least two detection apparatuses is small, thus the accuracy of the detected state of the target object is also high.

[0071] FIG. 4 is an illustrative embodiment related to the above block S10, which is configured to define an example solution of detecting a target object in a scenario where the air conditioner is in a first mode. The method includes the following blocks.

[0072] At block S11, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to an indication of controlling the air conditioner to enter a first mode.

[0073] In an example, an air conditioner mode includes the first mode. In the first mode, a power consumption value of the air conditioner is less than a predetermined power consumption value, that is, the power consumption of the air conditioner is low. For example, the first mode may be an energy-saving mode.

[0074] The energy-saving mode refers to a mode in which an operating power consumption of the air conditioner is less than the predetermined power consumption value, that is, a low-power mode. In the energy-saving mode, the air conditioner may operate according to a preset frequency, an expansion valve opening, a temperature, a wind speed and other air conditioner parameters, to enable the power consumption of the air conditioner to be less than predetermined power consumption value. The energy-saving mode includes at least one of a heat preservation mode and a standby mode. In the heat preservation mode, the air conditioner may adjust an indoor temperature to a preset temperature value, and continuously detect the indoor temperature, and control the indoor temperature to maintain at the preset temperature value. For example, when the indoor temperature is higher than the preset temperature value, the air conditioner may activate a cooling function to reduce the indoor temperature to the preset temperature value. When the indoor temperature is lower than the preset temperature value, the air conditioner may activate a heating function to increase the indoor temperature to the preset temperature value. Compared to continuous cooling or heating with high strength, an operating power of the air conditioner in the heat preservation mode can be dynamically adjusted according to an actual indoor temperature. The operating power is usually lower, which can save energy to a certain extent. Therefore, the heat preservation mode can be one of the energy-saving modes. The standby mode refers to a situation where some circuits of the air conditioner are still powered on after being turned off, to maintain basic functions of the air conditioner. These basic functions may include, for example, a function of receiving a signal from a remote controller and a function of displaying a clock on a display panel of the air conditioner, etc. These basic functions facilitate the air conditioner to quickly respond to user indications to start. For example, when receiving a power on indication sent by the remote controller, the air conditioner may quickly switch from the standby mode to an operating mode. Compared to restarting the air conditioner after complete power down, a startup speed of the air conditioner is faster and can restore previous setting parameters, such as temperature setting and the wind speed, etc. Due to a situation where main power consuming devices such as a compressor and a fan of the air conditioner have stopped working in the standby mode, an overall power consumption of the air conditioner is relatively low. Therefore, the standby mode can also be referred to as one of the energy-saving modes.

[0075] The indication of controlling the air conditioner to enter the first mode may be the indication of controlling the air conditioner to enter the first mode which is triggered by a user on the remote controller, or may be the indication of controlling the air conditioner to enter the first mode which is triggered by the user on a terminal (such as a mobile phone, a tablet and other portable devices), or may be the indication of controlling the air conditioner to enter the first mode which is triggered by the user on the air conditioner. When the indication of controlling the air conditioner to enter the first mode is triggered, it means that the user wants to trigger the air conditioner to enter the first mode, and the user selects the first mode on the remote controller, the mobile phone or the air conditioner. When the user selects the first mode, the air conditioner can detect the state of the target object in the first detection mode with higher sensitivity to determine presence or absence of a user with a micro motion indoors, thus reducing occurrence of missed detection on the user with the micro motion. It is understandable that when the user selects the first mode for the air conditioner to enter, a sensitivity of a second detection mode is relatively low, and it is impossible to detect the presence or absence of the user with the micro motion indoors. Therefore, the first detection mode with higher sensitivity needs to be used to detect the presence or absence of the user with the micro motion indoors, to determine whether an operation of the user selecting the first mode for the air conditioner to enter is a missed operation.

[0076] In an example, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting no target object, the air conditioner is controlled to enter a state corresponding to the first mode.

[0077] As shown in FIG. 5, when the air conditioner is selected to be in the first mode 501 with low power consumption, it may be preliminarily determined that the user wants to control the air conditioner to enter the first mode, and when no target is detected through the first detection mode of the static detection, it means that no user is present indoors, and selecting the first mode for the air conditioner to enter by the user is not a missed operation. In this case, the air conditioner may be controlled to enter the state corresponding to the first mode to meet a demand of the user and reduce the energy consumption of the air conditioner. The state corresponding to the first mode refers to a state that the main power consumption devices in the air conditioner is turned off while the basic functions of the air conditioner are retained.

[0078] In some scenarios, when the user goes outdoors, the user may remotely control the air conditioner to be in the first mode with low power consumption through the mobile phone. In this case, when the detection apparatus group on the air conditioner detects absence of the target object indoors through the first detection mode of static detection, the air conditioner may be controlled to enter the state corresponding to the first mode, to meet a demand of the user for the low power consumption of the air conditioner.

[0079] In an example, the detection apparatus group is controlled to be in the first detection mode 511 to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting a target object, the air conditioner is controlled to continue in the first detection mode to detect the state of the target object.

[0080] As shown in FIG. 5, when the user selects the air conditioner to be in the first mode of low power consumption and the detection apparatus group detects the state of the target object in the first detection mode of static detection, in response to detecting the target object through the first detection mode of static detection, it means that the user is present 521 indoors but the user does not move, such as the user sitting and resting indoors, lying down and resting, etc. In this case, the air conditioner continues to maintain 531 the first detection mode, to monitor the presence or absence of the user with the micro motion indoors in real time. When the micro motion is present indoors, it means that the use selecting the first mode may be the missed operation, and the air conditioner may be controlled not to enter the state corresponding to the first mode.

[0081] In some scenarios, when the user is indoors and the user does not move, in response to the user accidentally controls the air conditioner to be in the first mode with low power consumption through the mobile phone / remote controller, when the detection apparatus group on the air conditioner detects the presence of the target object with the micro motion indoors through the first detection mode of static detection, it means that the user accidentally touches selection on the first mode, then the air conditioner may be controlled not to enter the state corresponding to the first mode, and continue to be kept in a state of cooling or heating for the user, thus improving user experiences.

[0082] In an example, the detection apparatus group is controlled to be in the first detection mode 510 to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting no target object 520, the air conditioner is controlled 530 to switch from the first detection mode 510 to the second detection mode 511.

[0083] In the second detection mode 511, the at least two detection apparatuses in the detection apparatus group simultaneously perform detection of the target object. The detection of the target object 523 may refer to the detection apparatus group detecting the state of the target object.

[0084] The at least two detection apparatuses in the detection apparatus group simultaneously perform detection on the target object in the second detection mode. Simultaneously performing the detection on the target object may be referred to as dynamic detection. A sensitivity of the dynamic detection is relatively low than a sensitivity of the static detection, which can also be understood that a detection sensitivity of the detection apparatus group in the second detection mode is lower than a detection sensitivity of the detection apparatus group in the first detection mode. The dynamic detection is configured to monitor a position of the target object in real time. When a distance between two adjacent target object positions is greater than a first predetermined distance, it is considered that the target object is in dynamic activity. For example, a user is walking indoors, then monitoring may be performed through the dynamic detection.

[0085] A detection sensitivity of the at least two detection apparatuses during the dynamic detection may be set relatively lower than a detection sensitivity of the at least two detection apparatuses in the static detection. Due to the relatively low sensitivity of the at least two detection apparatuses during the dynamic detection, the at least two detection apparatuses has less interference with each other during operation. For example, as illustrated in FIG. 2, due to the low sensitivity of a detection apparatus A, it is difficult to detect a detection signal emitted by a detection apparatus B. Similarly, due to the low sensitivity of the detection apparatus B, it is also difficult to detect a detection signal emitted by the detection apparatus A. Therefore, the at least two detection apparatuses may be controlled to simultaneously turn on for dynamic detection of the target object, firstly, the detection sensitivity of the detection apparatus is relatively low, and there is less interference between the at least two detection apparatuses, thus the accuracy of the detected state of the target object is improved; secondly, the at least two detection apparatuses simultaneously detecting the target object may expand the detection range.

[0086] When the air conditioner is in the first mode with low power consumption and the detection apparatus group detects the state of the target object in the first detection mode of static detection, in response to detecting no target object through the static detection, it means that no target object is present indoors. In this case, the detection apparatus group may be controlled to switch from the first detection mode to the second detection mode. Since the at least two detection apparatuses simultaneously perform the detection in the second detection mode, a detection range of the at least two detection apparatuses under simultaneous detection is wider. Compared with the first detection mode in which the at least two detection apparatuses alternately perform the detection, when the user goes indoors, the second detection mode may more quickly detect the target object going indoors, and then operation of the air conditioner can be quickly controlled based on the state of indoor target object from a state of absence of the target object to a state of presence of the target object, thus improving user experience.

[0087] In an example, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting no target object within a predetermined time period, the air conditioner is controlled to switch from the first detection mode to the second detection mode.

[0088] Taking the predetermined time period being 10 minutes as an example, when the air conditioner is selected to enter the first mode with low power consumption, the control detection apparatus group is controlled to be in the first detection mode of static detection. In response to the detection apparatus group detecting no target object within 10 minutes, it means that no user is present indoors. In this case, the control detection apparatus group is controlled to switch from the first detection mode of static detection to the second detection mode of dynamic detection.

[0089] By setting the predetermined time period, the detection apparatus group may be controlled in the first detection mode to determine the really presence or absence of the user indoors with a relatively long predetermined time period. It is determined whether the user has a static behavior within the predetermined time period, thus reducing a situation of missed detection on the user. For example, taking the predetermined time period being 10 minutes as an example, in some scenarios, the user has no static action in the first 5 minutes, but occurs a static behavior of shaking a head in the 6th minute. In response to no predetermined time period setting, the detection apparatus group in the first detection mode of static detection can switch to the second detection mode in a case where the detection apparatus group detects no user within a 10s round of detection. In the second detection mode, the detection apparatus group cannot detect the user who has the static behavior of shaking the head. By setting the predetermined time period, within 10 minutes, the detection apparatus group can repeatedly perform a plurality of rounds of detection to detect the presence or absence of the user with the static behavior indoors, thus detecting the user with the static behavior at the 6th minute and reducing occurrence of missed detection of the user.

[0090] In an example, when the detection apparatus group is in the second detection mode, in response to detecting a target object, the detection apparatus group is controlled to switch from the second detection mode to the first detection mode.

[0091] As shown in FIG. 5, when the user selects the air conditioner to be in the first mode with the low power consumption, and the detection apparatus group switches from the first detection mode to the second detection mode, in response to detecting the target object through the second detection mode, it means that the user is indoors. In this case, the detection apparatus group may be controlled to switch 532 from the second detection mode 511 to the first detection mode 510, such that the subsequent detection of the target object can be performed in the first detection mode with higher sensitivity. In response to still detecting the user indoors subsequently, it means that the user indoors still requires the operation of the air conditioner, and the user selecting the first mode with the low power consumption for the air conditioner is a missed operation behavior, then the air conditioner can be controlled to maintain a previous operating state, thus improving the user experience.

[0092] By means of the above technical solution, in a first aspect, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. After the user selects the first mode, it may further assist in determining whether the user has an intention to turn on the first mode of the air conditioner in combination with the state of the target detection. After the intention is determined accurately, the operation control of the air conditioner can be more accurate. In a second aspect, when it is not possible to determine the presence or absence of the user indoors in the second detection mode (such as dynamic detection), it may be determined the presence or absence of the user with the micro motion indoors through the first detection mode (such as static detection), thus reducing missed detection of the user. In a third aspect, when the detection apparatus group is in the first detection mode, in response to detecting no target object, the detection apparatus group is controlled to switch from the first detection mode to the second detection mode. When it is clearly determined in the first detection mode that no user is present indoors, the detection apparatus group may be switched from the first detection mode to the second detection mode, thus, the detection range of the detection apparatus group can be expanded, and it can quickly determine that the user goes indoors when the user has just gone indoors. In the fourth aspect, when the detection apparatus group is in the first detection mode, in response to detecting no target object within the predetermined time period, the detection apparatus group is controlled to switch from the first detection mode to the second detection mode, thus, a detection duration of the detection apparatus group in the first detection mode may be improved and occurrence of missed detections caused by long-term inactivity of the user may be reduced.

[0093] FIG. 6 is an illustrative embodiment related to the above block S20, which is configured to define an example solution of detecting a target object in a scenario where the air conditioner is in a second mode. The method includes the following blocks.

[0094] At block S21, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to an indication of controlling the air conditioner to enter a second mode.

[0095] In an example, an air conditioner mode includes the second mode. In the second mode, a power consumption value of the air conditioner is greater than or equal to a predetermined power consumption value. The power consumption value of the air conditioner in the second mode is greater than a power consumption value of the air conditioner in the first mode. For example, the second mode may include a linkage mode.

[0096] The linkage mode refers to a mode of linkage interaction between the user and the air conditioner, which is configured to indicate that a state of airflow output from the air conditioner is correlated with a state of a person, and to control a wind speed and / or a wind direction output by the air conditioner to change with a position of the user. The linkage mode includes at least one of a wind blowing person mode, a wind avoidance person mode, or a person-proximity soft wind mode. The wind blowing person mode indicates that a direction of the airflow output from the air conditioner follows a movement of the person. For the wind blowing person mode, when the air conditioner turns on the wind blowing person mode, a deflection angle of an air guide direction of the air conditioner may be controlled according to the monitored state of the target object, causing the air guide direction of the air conditioner being directed towards the target object, achieving a function of the wind following the movement of the person with precise control. Up, down, left, and right deflection angles of a wind deflector of the air conditioner may be calculated by detecting the state of the target object (such as a position of the target object), and control the air guide direction of the air conditioner to follow the movement of the target object. The wind avoidance person mode indicates that the direction of the airflow output from the air conditioner avoids the person. For the wind avoidance person mode, when the air conditioner turns on the wind avoidance person mode, an offset angle of the air guide direction of the air conditioner may be controlled based on the monitored state of the target object, causing the air guide direction of the air conditioner to avoid the target object, achieving a wind avoidance person function with precise wind control. Up, down, left, and right deflection angles of an air guide plate of the air conditioner may be calculated by detecting the state of the target object (such as a position of the target object), and control the air guide direction of the air conditioner to offset from the target object, achieving an effect of preventing cold air from blowing the person directly. The person-proximity soft wind mode refers to controlling the wind speed of the airflow output from the air conditioner to be less than a predetermined wind speed when a distance between the person and the air conditioner is less than a predetermined distance. For the person-proximity soft wind mode, the distance between the target object and the air conditioner may be determined based on the detected state of the target object (such as the position of the target object). The wind speed output by the air conditioner is controlled to be less than the predetermined wind speed when determining that the distance between the target object and the air conditioner is less than the predetermined distance, thus improving air supply softness of the air conditioner. When the distance between the target object and the air conditioner is less than the predetermined distance, the wind speed output by the air conditioner may gradually decrease as the distance between the target object and the air conditioner decreases, such that the wind speed perceived by the user tends to be constant as they get closer to the air conditioner, which can further improve user experience.

[0097] The indication of controlling the air conditioner to enter the second mode may be the indication of controlling the air conditioner to enter the second mode which is triggered by a user on the remote controller, or may be the indication of controlling the air conditioner to enter the second mode which is triggered by the user on a terminal (such as a mobile phone, a tablet and other portable devices), or may be the indication of controlling the air conditioner to enter the second mode which is triggered by the user on the air conditioner. When the indication of controlling the air conditioner to enter the second mode is triggered, it means that the user wants to trigger the air conditioner to enter the second mode, and the user selects the second mode on the remote controller, the mobile phone or the air conditioner. When the user selects the second mode, the air conditioner can detect the state of the target object in the second detection mode.

[0098] When the user selects the air conditioner to be in the second mode, it indicates that the user requires the air conditioner to adjust the wind speed and the wind direction of the air conditioner in real time according to the position of the target object. In this case, since the position of the target indoors is moving, a behavior of the user is a dynamic behavior, and the position of the target object may be detected through the second detection mode with relatively low sensitivity. Therefore, when the user selects the air conditioner to be in the second mode, the detection apparatus group may be controlled to be in the second detection mode to detect the state of the target object, to determine the position of the user.

[0099] For example, when the user selects the air conditioner to be in the wind blowing person mode, it indicates that the user needs an air outlet direction of the air conditioner to blow towards the user itself. In this case, the detection apparatus group may be in the second detection mode to detect the state of the target object, with a wider detection range to detect the presence of the user indoors, and then the air outlet direction of the air conditioner may blow towards the user.

[0100] For example, when the user selects the air conditioner to be in the wind avoidance person mode, it indicates that the user needs the air outlet direction of the air conditioner to avoid the user itself. In this case, the detection apparatus group may be in the second detection mode to detect the state of the target object, with a wider detection range to detect the presence of the user indoors, and then the air outlet direction of the air conditioner may avoid the user.

[0101] For example, when the user selects the air conditioner to be in the person-proximity soft wind mode, it indicates that the user needs the air outlet speed of the air conditioner to decrease when the user approaches. In this case, the control detection apparatus group may be in the second detection mode to detect the state of the target object, with a wider detection range to detect the presence of the user indoors. When the position of the user is close to the air conditioner, the air outlet speed of the air conditioner is controlled to be less than the predetermined wind speed, thus, the airflow is output the air conditioner at a smaller wind speed and the air supply softness of the air conditioner is improved.

[0102] In an example, in a case where the air conditioner is in the person-proximity soft wind mode and the detection apparatus group is in the second detection mode, in response to detecting no target object within a predetermined range and detecting a target object outside the predetermined range, the detection apparatus group is controlled to switch to the first detection mode.

[0103] The predetermined range is a circular range with a center of the air conditioner as an origin and a predetermined distance from the origin. The predetermined range may also be a circular range with a center of the detection apparatuses on the air conditioner as the origin and the predetermined distance from the origin. The present invention does not limit the range. The preset distance may be 3m, which is not limited by the present invention.

[0104] When the user selects the air conditioner to be in the person-proximity soft wind mode, it indicates that the user needs the air outlet speed of the air conditioner to decrease when the user approaches. In this case, in response to detecting no target object within the predetermined range and detecting the target object outside the predetermined range through the second detection mode, it indicates that no target object is in a region close to the air conditioner, while the target object is in a region far away from the air conditioner, indicating that the presence or absence of the target object in the region close to the air conditioner cannot be detected through the second detection mode. In this case, the detection apparatus group may be switched from the second detection mode to the first detection mode, to detect the presence or absence of the target object within the predetermined range close to the air conditioner in the first detection mode with higher sensitivity. In response to detecting the target object, it is determined to control the air conditioner to enter a state corresponding to the person-proximity soft wind mode, and in response to detecting no target object, the air conditioner is controlled not to enter the state corresponding to the person-proximity soft wind mode.

[0105] In some scenarios, when the user selects the person-proximity soft wind mode, it indicates that the user needs the air outlet speed of the air conditioner to decrease as the user approaches, and the user may remain stationary in case of reaching the predetermined range of the air conditioner. In this case, the presence of the user with the static behavior within the predetermined range of the air conditioner cannot be detected using the second detection mode. Therefore, when the user selects the air conditioner to be in the person-proximity soft wind mode and the detection apparatus group is in the second detection mode, in response to the detection apparatus group detecting no target object within the predetermined range in the second detection mode, the detection apparatus group may be controlled to switch from the second detection mode to the first detection mode, thus, it may be determined the presence or absence of the target object within the predetermined range in the detection mode with higher sensitivity and situations where no target object is detected in case of the target object being within the predetermined range may be reduced.

[0106] In an example, in a case where the detection apparatus group is in the second detection mode to detect the state of the target object, in response to detecting no target object, the detection apparatus group is controlled to switch from the second detection mode to the first detection mode.

[0107] Generally, the air conditioner may detect the presence or absence of the target object dynamically moving indoors through the second detection mode of dynamic detection. When detecting the movement of the target object indoors, it indicates the presence of the target object. To ensure comfort experience of the target object, the air conditioner is controlled to be in a normal mode for normal operation, to cool or heat the target object normally. However, when detecting that the indoor target object has not moved through the second detection mode of dynamic detection, it indicates the presence of no target object indoors. When the target object stops moving indoors, a micro motion behavior in a state where the target object stops moving cannot be detected through the second detection mode of dynamic detection. Therefore, it is necessary to combine the first detection mode proposed in an embodiment of the present invention to detect the state of the target object, whether the state of the target object has changed may be detected through the first detection mode of static detection. In response to the state of the target object having changed, it is considered to that the target object has the micro motion behavior, indicating that the target object still exists indoors, thus avoiding missed detection of the target object.

[0108] For example, the micro motion of the target object cannot be detected through the second detection mode of dynamic detection, then the detection apparatus group may be controlled to be in the first detection mode. In the first detection mode, the sensitivity of the detection apparatus group may be increased to perform static detection on the micro motion of the target object indoors with higher sensitivity, thus avoiding missed detection of the target object. And the at least two detection apparatuses in the detection apparatus group alternatively performs the detection, therefore, the at least two detection apparatuses do not interfere with each other, ensuring a detection accuracy of the detection apparatus group. In the first detection mode, the detection apparatus group can detect the micro motion of the target object indoors in a highly sensitive, highly accurate, and wide detection range manner.

[0109] In an example, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the second mode. The air conditioner is maintained in a state corresponding to the second mode in response to detecting no target object.

[0110] When the user selects the second mode for the air conditioner to enter, it indicates that the user wants to be able to adjust the wind speed and the wind direction of the air conditioner in real time according to the position of the user. In this case, the state of the target object may be detected in the second detection mode with relatively low sensitivity. In response to detecting no moving target object indoors, the air conditioner may be controlled to keep in the state corresponding to the second mode. The state corresponding to the second mode indicates that the wind deflector and a wind speed level of the air conditioner are in a state required by the user.

[0111] In some scenarios, when the user has a distance of 100m away from home, the user may select the second mode for the air conditioner to enter remotely on a mobile phone of the user. When the detection apparatus group on the air conditioner detects that no target object is present indoors in the second detection mode, it may still control the air conditioner to enter the state corresponding to the second mode, such that when the user enters the home, the air conditioner can interact with the user according to the second mode set by the user. For example, in response to a mode set by the user being the wind blowing person mode, when the user enters the home, the air conditioner may immediately direct the output airflow to the user according to the wind blowing person mode set by the user, reducing a response duration of the wind blowing person mode and improving the user experience.

[0112] In an example, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the second mode. In response to detecting no target object, the wind deflector and / or the wind speed level of the air conditioner are maintained in a state when the target object is detected at a most recently time point.

[0113] When the user selects the second mode for the air conditioner to enter, it means that the user wants to be able to adjust the wind speed and the wind direction of the air conditioner in real time according to the position of the user. In this case, the state of the target object may be detected by the second detection mode with relatively low sensitivity. In response to detecting no moving target indoors, the wind deflector and / or the wind speed level of the air conditioner may be controlled to be in the state when the target object is detected at the most recently time point, until the movement of the target object is detected.

[0114] In some scenarios, when the user selects the wind blowing person mode for the air conditioner to enter, in response to the indoor user moves to a position A in a previous time point, the air conditioner may control its own wind deflector to direct towards the position A. In response to the user being at the position A and no longer moving in the next time point, the detection apparatus group on the air conditioner is in the second detection mode and cannot detect the target object. In this case, a direction of the wind deflector of the air conditioner may also direct towards the position A, to output airflow to the user at the position A, thus avoiding the direction of the wind deflector of the air conditioner from directing towards other positions and improving the user experience.

[0115] By means of the above technical solution, in a first aspect, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the second mode. When the user selects the second mode, it may further assist the control of the air conditioner in combination with the state of the target object, and the user experience may be improved. In a second aspect, when the user selects the air conditioner to be in the second mode, the detection apparatus group may be controlled to perform detection on the target object in the second detection mode. In the second detection mode, the at least two detection apparatuses in the detection apparatus group simultaneously perform the detection of the target object, which may expend the detection range. In a third aspect, the user selecting the second mode for the air conditioner may refer to that it is desired to adjust, by the air conditioner, the wind speed and the wind direction of the air conditioner according to the dynamic behavior of the user, and the dynamic behavior of the user can be detected by the second detection mode with relatively low sensitivity, thus, the dynamic behavior of the user obtained by directly using the second detection mode with relatively low sensitivity, for example, control for the state of the air conditioner in the second mode can be achieved based on the position of the user.

DETAILED DESCRIPTION

[0037] Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of embodiments do not represent all implementations consistent with the present invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the present invention as recited in the appended claims.

[0038] It is noted that all actions for acquiring signals, information, or data in the invention are carried out in accordance with relevant data protection regulations and policies of the country where they are located, and with authorization granted by owners of corresponding apparatuses.

[0039] FIG. 1 is a flowchart illustrating an air conditioner control method according to an embodiment. As illustrated in FIG. 1, the method includes the following blocks.

[0040] At block S10, a detection apparatus group is controlled to be in different detection modes to detect a state of a target object.

[0041] The detection apparatus group includes at least two detection apparatuses installed on an air conditioner, with a predetermined distance between the at least two detection apparatuses, and the detection apparatus group is wired coupled to a microcontroller unit (MCU) of an indoor unit of the air conditioner.

[0042] As shown in FIG. 2, two detection apparatuses such as a detection apparatus A (a radar A 20 in FIG. 2) and a detection apparatus B 21 (a radar B in FIG. 2) may be installed on the indoor unit of the air conditioner 23. These two detection apparatuses are installed at a certain angle to improve a detection range for detecting the target object. As shown in FIG. 3, the detection apparatus A 30 is coupled to the MCU 31 via a communication port 1, the detection apparatus B 32 is coupled to the MCU via a communication port 2. The MCU is also coupled to a WIFI module 33, and the WIFI module may communicate with a cloud.

[0043] In an example, the two detection apparatuses in the at least two detection apparatuses are arranged oppositely. The detection apparatus may be a radar.

[0044] For example, detection surfaces of the two detection apparatuses may be arranged oppositely, and there is an overlapping part between the detection surfaces of the two detection apparatuses. The detection surface refers to a region area that the detection apparatus can perceive, as shown in FIG. 2, the detection surfaces of the two detection apparatuses are fan-shaped. For example, detection directions of the two detection apparatuses may be arranged oppositely, and there is an intersection between the detection directions of the two detection apparatuses. For example, the two detection apparatuses themselves may also be arranged oppositely. A form of arranging the two detection apparatuses oppositely is not limited by the invention.

[0045] In an example, the detection modes include at least two of a first detection mode, a second detection mode, or a third detection mode.

[0046] In an example, the detection apparatus group includes at least two detection apparatuses. In the first detection mode, the at least two detection apparatuses alternately perform detection on the state of the target object.

[0047] In the first detection mode, the at least two detection apparatuses in the detection apparatus group alternately perform detection on the target object using a time division multiplexing manner. Alternatively, performing the detection on the target object may be referred to as static detection, and the static detection has a relatively high sensitivity for detecting the target object. The static detection is configured to detect whether the target object has a micro motion. When a distance between two adjacent target object positions generated by the same target object is greater than a second predetermined distance and less than a first predetermined distance, it is considered that the target object is in the micro motion. Or, when two adjacent poses generated by the same target object are different, it is considered that the target object is in the micro motion. For example, the target object has the micro motion in arms, fingers, a head, feet or other body parts indoors or the target object moves on a sofa, then monitoring may be performed through the first detection mode with the static detection.

[0048] For example, within a single 20 milliseconds time period, the MCU may control the detection apparatus A to turn on and the detection apparatus B to turn off during a first 10 milliseconds time period, such that the detection apparatus A may perform detection on the target object first during the first 10 milliseconds time period. During the last 10 milliseconds time period, the MCU may control the detection apparatus B to turn on and the detection apparatus A to turn off, such that the detection apparatus B may perform detection on the target object during the last 10 milliseconds time period. As such, using every 20 milliseconds as a cycle, the two detection apparatuses alternately perform detection on the target object during each cycle.

[0049] During the static detection, due to the relatively high sensitivity of the at least two detection apparatuses on the air conditioner, at least two detection apparatuses with the same frequency and the same sensitivity may interfere with each other during operation. For example, a detection signal emitted by the detection apparatus A may be detected by the detection apparatus B, which may interfere with determination of the detection apparatus B. Similarly, a detection signal emitted by the detection apparatus B may also be detected by the detection apparatus A, which may interfere with determination of the detection apparatus A. Thus, the state of the target object detected by the at least two detection apparatuses may be inaccurate. On the basis of this, with controlling the at least two detection apparatuses to alternately perform the static detection on the target object, firstly, the detection apparatus has a high detection sensitivity, it may detect a micro change in the state of the target object; secondly, the at least two detection apparatuses alternately performing detection on the target object may expand the detection range; thirdly, a single detection apparatus is activated at the same time, then the single detection apparatus may not be interfered by other turned-off detection apparatuses, and the detected pose of the target object may be more accurate.

[0050] In an example, the detection apparatus group includes at least two detection apparatuses. In the second detection mode, the at least two detection apparatuses simultaneously perform detection on the state of the target object. A sensitivity of the detection apparatus group in the first detection mode is greater than a sensitivity of the detection apparatus group in the second detection mode.

[0051] In the second detection mode, the at least two detection apparatuses in the detection apparatus group simultaneously perform detection on the target object. Simultaneously performing the detection on the target object may be referred to as dynamic detection. A sensitivity of the dynamic detection is relatively low than a sensitivity of the static detection. The dynamic detection is configured to monitor a position of the target object in real time. When the distance between two adjacent target object positions generated by the same target object is greater than the first predetermined distance, it is considered that the target object has dynamic behavior and the target object position is detected. For example, a user is walking indoors, then monitoring may be performed through the dynamic detection.

[0052] During the dynamic detection, due to the relatively low sensitivity of the at least two detection apparatuses, the at least two detection apparatuses has less interference with each other during operation. For example, due to the low sensitivity of the detection apparatus A, it is difficult to detect the detection signal emitted by the detection apparatus B. Similarly, due to the low sensitivity of the detection apparatus B, it is also difficult to detect the detection signal emitted by the detection apparatus A. Therefore, the at least two detection apparatuses may be controlled to simultaneously turn on for dynamic detection of the target object, firstly, the detection sensitivity of the detection apparatus is relatively low, and there is less interference between the at least two detection apparatuses, thus the accuracy of the detected state of the target object is improved; secondly, the at least two detection apparatuses simultaneously detecting the target object may expand the detection range; thirdly, since the dynamic detection involves a significant change in the target object, using the dynamic detection is sufficient to detect the dynamic behavior of the target object.

[0053] In an example, the detection apparatus group includes at least one detection apparatus. In the third detection mode, one detection apparatus performs detection on the state of the target object.

[0054] For example, when a distance between the target object and one target detection apparatus of the at least two detection apparatuses is close, the target detection apparatus may be controlled to perform the detection on the state of the target object, such that other detection apparatuses can pause performing the detection on the state of the target object, thus saving energy consumption.

[0055] The distance between the target object and the detection apparatus may be indicated by a signal strength. The stronger the signal strength of the target object detected by the detection apparatus, the closer the distance between the target object and the detection apparatus. Therefore, a detection apparatus corresponding to a strongest signal strength selected from a plurality of signal strengths may be taken as the target detection apparatus closest to the target object.

[0056] In the third detection mode, the one detection apparatus may perform the detection on the state of the target object at a predetermined duration interval.

[0057] Taking the predetermined duration interval being 10 milliseconds as an example, the target detection apparatus may perform the detection on the state of the target object at a 10 milliseconds interval, without a need to detect the state of the target object in real time, to further save the energy consumption.

[0058] At block S20, control operation of the air conditioner based on the state of the target object.

[0059] In an example, the state of the target object includes presence or absence of the target object, a position of the target object, a dynamic and static state, and a pose of the target object.

[0060] The presence or absence of the target object refers to whether the target object exists indoors.

[0061] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in the presence of the target object indoors; and controlling the air conditioner to turn off in the absence of the target object indoors.

[0062] The position of the target object refers a position of the target object indoors in the presence of the target object, which may be represented by coordinates of the target object indoors or a latitude and a longitude of the target object.

[0063] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in a case where the target object is indoors; and controlling the air conditioner to turn off in a case where the target object is outdoors.

[0064] The dynamic and static state of the target object include a dynamic state and a static state. When the position of the target object changes indoors or the distance between two adjacent positions of the target object is greater than the first predetermined distance, the target object is in the dynamic state. When the position of the target object remains unchanged indoors, or when the distance between two adjacent positions of the target object is greater than the second predetermined distance and less than the second predetermined distance, the target object is in the static state.

[0065] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in a case of the presence of the target object indoors and an indoor target object being in the dynamic state or the static state.

[0066] The pose of the target object includes a change in the pose of the target object indoors.

[0067] In an example, controlling the operation of the air conditioner based on the state of the target object includes: controlling the operation of the air conditioner in a case of the presence of the target object indoors and the pose of the target object changing.

[0068] In related arts, a single detection apparatus is configured on the air conditioner to detect a target object indoors. However, the detection range of the single detection apparatus is limited, and targets outside the detection range of the detection apparatus cannot be detected by the detection apparatus, which may result in missed detection of targets. On the basis of this, the at least two detection apparatuses may be configured on the air conditioner to detect the indoor target object, but the at least two detection apparatuses have the relatively high detection sensitivity, especially for static detection of the target object, the at least two detection apparatuses require higher sensitivity. At least two detection apparatuses with the same frequency and the same sensitivity may interfere with each other during operation, resulting in an error in the detected state of the target object. For example, the detection signal emitted by the detection apparatus A may be detected by the detection apparatus B, which may interfere with determination of the detection apparatus B. Similarly, the detection signal emitted by the detection apparatus B may also be detected by the detection apparatus A, which may interfere with determination of the detection apparatus A. Thus, the state of the target object detected by the at least two detection apparatuses may be inaccurate.

[0069] By means of the above technical solution, the detection apparatus group may be controlled to detect the state of the target object in the first detection mode, and the at least two detection apparatuses in the detection apparatus group may alternately detect the target object in the first detection mode. Firstly, the detection apparatus has a high detection sensitivity, it may detect a micro change in the state of the target object. Secondly, taking the at least two detection apparatuses including two detection apparatuses as an example, in a scenario where the two detection apparatuses alternately perform the detection on the state of the target object, although one detection apparatus pauses detection while the other detection apparatus detects, the two detection apparatuses frequently switch back and forth for detection. Therefore, switching back and forth for detection between the two detection apparatuses can also comprehensively detect the target object surrounding the air conditioner and expand the detection range. Thirdly, a single detection apparatus is activated at the same time, then the single detection apparatus may not be interfered by other turned-off detection apparatuses, and the detected pose of the target object may be more accurate.

[0070] The detection apparatus group may also be controlled to detect the state of the target object in the second detection mode. Firstly, in the second detection mode, the at least two detection apparatuses in the detection apparatus group simultaneously perform the detection of the target object, thus the detection range is wider. Secondly, in the second detection mode, the at least two detection apparatuses has the relatively low detection sensitivity, and the interference between the at least two detection apparatuses is small, thus the accuracy of the detected state of the target object is also high.

[0071] FIG. 4 is an illustrative embodiment related to the above block S10, which is configured to define an example solution of detecting a target object in a scenario where the air conditioner is in a first mode. The method includes the following blocks.

[0072] At block S11, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to an indication of controlling the air conditioner to enter a first mode.

[0073] In an example, an air conditioner mode includes the first mode. In the first mode, a power consumption value of the air conditioner is less than a predetermined power consumption value, that is, the power consumption of the air conditioner is low. For example, the first mode may be an energy-saving mode.

[0074] The energy-saving mode refers to a mode in which an operating power consumption of the air conditioner is less than the predetermined power consumption value, that is, a low-power mode. In the energy-saving mode, the air conditioner may operate according to a preset frequency, an expansion valve opening, a temperature, a wind speed and other air conditioner parameters, to enable the power consumption of the air conditioner to be less than predetermined power consumption value. The energy-saving mode includes at least one of a heat preservation mode and a standby mode. In the heat preservation mode, the air conditioner may adjust an indoor temperature to a preset temperature value, and continuously detect the indoor temperature, and control the indoor temperature to maintain at the preset temperature value. For example, when the indoor temperature is higher than the preset temperature value, the air conditioner may activate a cooling function to reduce the indoor temperature to the preset temperature value. When the indoor temperature is lower than the preset temperature value, the air conditioner may activate a heating function to increase the indoor temperature to the preset temperature value. Compared to continuous cooling or heating with high strength, an operating power of the air conditioner in the heat preservation mode can be dynamically adjusted according to an actual indoor temperature. The operating power is usually lower, which can save energy to a certain extent. Therefore, the heat preservation mode can be one of the energy-saving modes. The standby mode refers to a situation where some circuits of the air conditioner are still powered on after being turned off, to maintain basic functions of the air conditioner. These basic functions may include, for example, a function of receiving a signal from a remote controller and a function of displaying a clock on a display panel of the air conditioner, etc. These basic functions facilitate the air conditioner to quickly respond to user indications to start. For example, when receiving a power on indication sent by the remote controller, the air conditioner may quickly switch from the standby mode to an operating mode. Compared to restarting the air conditioner after complete power down, a startup speed of the air conditioner is faster and can restore previous setting parameters, such as temperature setting and the wind speed, etc. Due to a situation where main power consuming devices such as a compressor and a fan of the air conditioner have stopped working in the standby mode, an overall power consumption of the air conditioner is relatively low. Therefore, the standby mode can also be referred to as one of the energy-saving modes.

[0075] The indication of controlling the air conditioner to enter the first mode may be the indication of controlling the air conditioner to enter the first mode which is triggered by a user on the remote controller, or may be the indication of controlling the air conditioner to enter the first mode which is triggered by the user on a terminal (such as a mobile phone, a tablet and other portable devices), or may be the indication of controlling the air conditioner to enter the first mode which is triggered by the user on the air conditioner. When the indication of controlling the air conditioner to enter the first mode is triggered, it means that the user wants to trigger the air conditioner to enter the first mode, and the user selects the first mode on the remote controller, the mobile phone or the air conditioner. When the user selects the first mode, the air conditioner can detect the state of the target object in the first detection mode with higher sensitivity to determine presence or absence of a user with a micro motion indoors, thus reducing occurrence of missed detection on the user with the micro motion. It is understandable that when the user selects the first mode for the air conditioner to enter, a sensitivity of a second detection mode is relatively low, and it is impossible to detect the presence or absence of the user with the micro motion indoors. Therefore, the first detection mode with higher sensitivity needs to be used to detect the presence or absence of the user with the micro motion indoors, to determine whether an operation of the user selecting the first mode for the air conditioner to enter is a missed operation.

[0076] In an example, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting no target object, the air conditioner is controlled to enter a state corresponding to the first mode.

[0077] As shown in FIG. 5, when the air conditioner is selected to be in the first mode 501 with low power consumption, it may be preliminarily determined that the user wants to control the air conditioner to enter the first mode, and when no target is detected through the first detection mode of the static detection, it means that no user is present indoors, and selecting the first mode for the air conditioner to enter by the user is not a missed operation. In this case, the air conditioner may be controlled to enter the state corresponding to the first mode to meet a demand of the user and reduce the energy consumption of the air conditioner. The state corresponding to the first mode refers to a state that the main power consumption devices in the air conditioner is turned off while the basic functions of the air conditioner are retained.

[0078] In some scenarios, when the user goes outdoors, the user may remotely control the air conditioner to be in the first mode with low power consumption through the mobile phone. In this case, when the detection apparatus group on the air conditioner detects absence of the target object indoors through the first detection mode of static detection, the air conditioner may be controlled to enter the state corresponding to the first mode, to meet a demand of the user for the low power consumption of the air conditioner.

[0079] In an example, the detection apparatus group is controlled to be in the first detection mode 511 to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting a target object, the air conditioner is controlled to continue in the first detection mode to detect the state of the target object.

[0080] As shown in FIG. 5, when the user selects the air conditioner to be in the first mode of low power consumption and the detection apparatus group detects the state of the target object in the first detection mode of static detection, in response to detecting the target object through the first detection mode of static detection, it means that the user is present 521 indoors but the user does not move, such as the user sitting and resting indoors, lying down and resting, etc. In this case, the air conditioner continues to maintain 531 the first detection mode, to monitor the presence or absence of the user with the micro motion indoors in real time. When the micro motion is present indoors, it means that the use selecting the first mode may be the missed operation, and the air conditioner may be controlled not to enter the state corresponding to the first mode.

[0081] In some scenarios, when the user is indoors and the user does not move, in response to the user accidentally controls the air conditioner to be in the first mode with low power consumption through the mobile phone / remote controller, when the detection apparatus group on the air conditioner detects the presence of the target object with the micro motion indoors through the first detection mode of static detection, it means that the user accidentally touches selection on the first mode, then the air conditioner may be controlled not to enter the state corresponding to the first mode, and continue to be kept in a state of cooling or heating for the user, thus improving user experiences.

[0082] In an example, the detection apparatus group is controlled to be in the first detection mode 510 to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting no target object 520, the air conditioner is controlled 530 to switch from the first detection mode 510 to the second detection mode 511.

[0083] In the second detection mode 511, the at least two detection apparatuses in the detection apparatus group simultaneously perform detection of the target object. The detection of the target object 523 may refer to the detection apparatus group detecting the state of the target object.

[0084] The at least two detection apparatuses in the detection apparatus group simultaneously perform detection on the target object in the second detection mode. Simultaneously performing the detection on the target object may be referred to as dynamic detection. A sensitivity of the dynamic detection is relatively low than a sensitivity of the static detection, which can also be understood that a detection sensitivity of the detection apparatus group in the second detection mode is lower than a detection sensitivity of the detection apparatus group in the first detection mode. The dynamic detection is configured to monitor a position of the target object in real time. When a distance between two adjacent target object positions is greater than a first predetermined distance, it is considered that the target object is in dynamic activity. For example, a user is walking indoors, then monitoring may be performed through the dynamic detection.

[0085] A detection sensitivity of the at least two detection apparatuses during the dynamic detection may be set relatively lower than a detection sensitivity of the at least two detection apparatuses in the static detection. Due to the relatively low sensitivity of the at least two detection apparatuses during the dynamic detection, the at least two detection apparatuses has less interference with each other during operation. For example, as illustrated in FIG. 2, due to the low sensitivity of a detection apparatus A, it is difficult to detect a detection signal emitted by a detection apparatus B. Similarly, due to the low sensitivity of the detection apparatus B, it is also difficult to detect a detection signal emitted by the detection apparatus A. Therefore, the at least two detection apparatuses may be controlled to simultaneously turn on for dynamic detection of the target object, firstly, the detection sensitivity of the detection apparatus is relatively low, and there is less interference between the at least two detection apparatuses, thus the accuracy of the detected state of the target object is improved; secondly, the at least two detection apparatuses simultaneously detecting the target object may expand the detection range.

[0086] When the air conditioner is in the first mode with low power consumption and the detection apparatus group detects the state of the target object in the first detection mode of static detection, in response to detecting no target object through the static detection, it means that no target object is present indoors. In this case, the detection apparatus group may be controlled to switch from the first detection mode to the second detection mode. Since the at least two detection apparatuses simultaneously perform the detection in the second detection mode, a detection range of the at least two detection apparatuses under simultaneous detection is wider. Compared with the first detection mode in which the at least two detection apparatuses alternately perform the detection, when the user goes indoors, the second detection mode may more quickly detect the target object going indoors, and then operation of the air conditioner can be quickly controlled based on the state of indoor target object from a state of absence of the target object to a state of presence of the target object, thus improving user experience.

[0087] In an example, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. In a case where the detection apparatus group is in the first detection mode, in response to detecting no target object within a predetermined time period, the air conditioner is controlled to switch from the first detection mode to the second detection mode.

[0088] Taking the predetermined time period being 10 minutes as an example, when the air conditioner is selected to enter the first mode with low power consumption, the control detection apparatus group is controlled to be in the first detection mode of static detection. In response to the detection apparatus group detecting no target object within 10 minutes, it means that no user is present indoors. In this case, the control detection apparatus group is controlled to switch from the first detection mode of static detection to the second detection mode of dynamic detection.

[0089] By setting the predetermined time period, the detection apparatus group may be controlled in the first detection mode to determine the really presence or absence of the user indoors with a relatively long predetermined time period. It is determined whether the user has a static behavior within the predetermined time period, thus reducing a situation of missed detection on the user. For example, taking the predetermined time period being 10 minutes as an example, in some scenarios, the user has no static action in the first 5 minutes, but occurs a static behavior of shaking a head in the 6th minute. In response to no predetermined time period setting, the detection apparatus group in the first detection mode of static detection can switch to the second detection mode in a case where the detection apparatus group detects no user within a 10s round of detection. In the second detection mode, the detection apparatus group cannot detect the user who has the static behavior of shaking the head. By setting the predetermined time period, within 10 minutes, the detection apparatus group can repeatedly perform a plurality of rounds of detection to detect the presence or absence of the user with the static behavior indoors, thus detecting the user with the static behavior at the 6th minute and reducing occurrence of missed detection of the user.

[0090] In an example, when the detection apparatus group is in the second detection mode, in response to detecting a target object, the detection apparatus group is controlled to switch from the second detection mode to the first detection mode.

[0091] As shown in FIG. 5, when the user selects the air conditioner to be in the first mode with the low power consumption, and the detection apparatus group switches from the first detection mode to the second detection mode, in response to detecting the target object through the second detection mode, it means that the user is indoors. In this case, the detection apparatus group may be controlled to switch 532 from the second detection mode 511 to the first detection mode 510, such that the subsequent detection of the target object can be performed in the first detection mode with higher sensitivity. In response to still detecting the user indoors subsequently, it means that the user indoors still requires the operation of the air conditioner, and the user selecting the first mode with the low power consumption for the air conditioner is a missed operation behavior, then the air conditioner can be controlled to maintain a previous operating state, thus improving the user experience.

[0092] By means of the above technical solution, in a first aspect, the detection apparatus group is controlled to be in the first detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the first mode. After the user selects the first mode, it may further assist in determining whether the user has an intention to turn on the first mode of the air conditioner in combination with the state of the target detection. After the intention is determined accurately, the operation control of the air conditioner can be more accurate. In a second aspect, when it is not possible to determine the presence or absence of the user indoors in the second detection mode (such as dynamic detection), it may be determined the presence or absence of the user with the micro motion indoors through the first detection mode (such as static detection), thus reducing missed detection of the user. In a third aspect, when the detection apparatus group is in the first detection mode, in response to detecting no target object, the detection apparatus group is controlled to switch from the first detection mode to the second detection mode. When it is clearly determined in the first detection mode that no user is present indoors, the detection apparatus group may be switched from the first detection mode to the second detection mode, thus, the detection range of the detection apparatus group can be expanded, and it can quickly determine that the user goes indoors when the user has just gone indoors. In the fourth aspect, when the detection apparatus group is in the first detection mode, in response to detecting no target object within the predetermined time period, the detection apparatus group is controlled to switch from the first detection mode to the second detection mode, thus, a detection duration of the detection apparatus group in the first detection mode may be improved and occurrence of missed detections caused by long-term inactivity of the user may be reduced.

[0093] FIG. 6 is an illustrative embodiment related to the above block S20, which is configured to define an example solution of detecting a target object in a scenario where the air conditioner is in a second mode. The method includes the following blocks.

[0094] At block S21, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to an indication of controlling the air conditioner to enter a second mode.

[0095] In an example, an air conditioner mode includes the second mode. In the second mode, a power consumption value of the air conditioner is greater than or equal to a predetermined power consumption value. The power consumption value of the air conditioner in the second mode is greater than a power consumption value of the air conditioner in the first mode. For example, the second mode may include a linkage mode.

[0096] The linkage mode refers to a mode of linkage interaction between the user and the air conditioner, which is configured to indicate that a state of airflow output from the air conditioner is correlated with a state of a person, and to control a wind speed and / or a wind direction output by the air conditioner to change with a position of the user. The linkage mode includes at least one of a wind blowing person mode, a wind avoidance person mode, or a person-proximity soft wind mode. The wind blowing person mode indicates that a direction of the airflow output from the air conditioner follows a movement of the person. For the wind blowing person mode, when the air conditioner turns on the wind blowing person mode, a deflection angle of an air guide direction of the air conditioner may be controlled according to the monitored state of the target object, causing the air guide direction of the air conditioner being directed towards the target object, achieving a function of the wind following the movement of the person with precise control. Up, down, left, and right deflection angles of a wind deflector of the air conditioner may be calculated by detecting the state of the target object (such as a position of the target object), and control the air guide direction of the air conditioner to follow the movement of the target object. The wind avoidance person mode indicates that the direction of the airflow output from the air conditioner avoids the person. For the wind avoidance person mode, when the air conditioner turns on the wind avoidance person mode, an offset angle of the air guide direction of the air conditioner may be controlled based on the monitored state of the target object, causing the air guide direction of the air conditioner to avoid the target object, achieving a wind avoidance person function with precise wind control. Up, down, left, and right deflection angles of an air guide plate of the air conditioner may be calculated by detecting the state of the target object (such as a position of the target object), and control the air guide direction of the air conditioner to offset from the target object, achieving an effect of preventing cold air from blowing the person directly. The person-proximity soft wind mode refers to controlling the wind speed of the airflow output from the air conditioner to be less than a predetermined wind speed when a distance between the person and the air conditioner is less than a predetermined distance. For the person-proximity soft wind mode, the distance between the target object and the air conditioner may be determined based on the detected state of the target object (such as the position of the target object). The wind speed output by the air conditioner is controlled to be less than the predetermined wind speed when determining that the distance between the target object and the air conditioner is less than the predetermined distance, thus improving air supply softness of the air conditioner. When the distance between the target object and the air conditioner is less than the predetermined distance, the wind speed output by the air conditioner may gradually decrease as the distance between the target object and the air conditioner decreases, such that the wind speed perceived by the user tends to be constant as they get closer to the air conditioner, which can further improve user experience.

[0097] The indication of controlling the air conditioner to enter the second mode may be the indication of controlling the air conditioner to enter the second mode which is triggered by a user on the remote controller, or may be the indication of controlling the air conditioner to enter the second mode which is triggered by the user on a terminal (such as a mobile phone, a tablet and other portable devices), or may be the indication of controlling the air conditioner to enter the second mode which is triggered by the user on the air conditioner. When the indication of controlling the air conditioner to enter the second mode is triggered, it means that the user wants to trigger the air conditioner to enter the second mode, and the user selects the second mode on the remote controller, the mobile phone or the air conditioner. When the user selects the second mode, the air conditioner can detect the state of the target object in the second detection mode.

[0098] When the user selects the air conditioner to be in the second mode, it indicates that the user requires the air conditioner to adjust the wind speed and the wind direction of the air conditioner in real time according to the position of the target object. In this case, since the position of the target indoors is moving, a behavior of the user is a dynamic behavior, and the position of the target object may be detected through the second detection mode with relatively low sensitivity. Therefore, when the user selects the air conditioner to be in the second mode, the detection apparatus group may be controlled to be in the second detection mode to detect the state of the target object, to determine the position of the user.

[0099] For example, when the user selects the air conditioner to be in the wind blowing person mode, it indicates that the user needs an air outlet direction of the air conditioner to blow towards the user itself. In this case, the detection apparatus group may be in the second detection mode to detect the state of the target object, with a wider detection range to detect the presence of the user indoors, and then the air outlet direction of the air conditioner may blow towards the user.

[0100] For example, when the user selects the air conditioner to be in the wind avoidance person mode, it indicates that the user needs the air outlet direction of the air conditioner to avoid the user itself. In this case, the detection apparatus group may be in the second detection mode to detect the state of the target object, with a wider detection range to detect the presence of the user indoors, and then the air outlet direction of the air conditioner may avoid the user.

[0101] For example, when the user selects the air conditioner to be in the person-proximity soft wind mode, it indicates that the user needs the air outlet speed of the air conditioner to decrease when the user approaches. In this case, the control detection apparatus group may be in the second detection mode to detect the state of the target object, with a wider detection range to detect the presence of the user indoors. When the position of the user is close to the air conditioner, the air outlet speed of the air conditioner is controlled to be less than the predetermined wind speed, thus, the airflow is output the air conditioner at a smaller wind speed and the air supply softness of the air conditioner is improved.

[0102] In an example, in a case where the air conditioner is in the person-proximity soft wind mode and the detection apparatus group is in the second detection mode, in response to detecting no target object within a predetermined range and detecting a target object outside the predetermined range, the detection apparatus group is controlled to switch to the first detection mode.

[0103] The predetermined range is a circular range with a center of the air conditioner as an origin and a predetermined distance from the origin. The predetermined range may also be a circular range with a center of the detection apparatuses on the air conditioner as the origin and the predetermined distance from the origin. The present invention does not limit the range. The preset distance may be 3m, which is not limited by the present invention.

[0104] When the user selects the air conditioner to be in the person-proximity soft wind mode, it indicates that the user needs the air outlet speed of the air conditioner to decrease when the user approaches. In this case, in response to detecting no target object within the predetermined range and detecting the target object outside the predetermined range through the second detection mode, it indicates that no target object is in a region close to the air conditioner, while the target object is in a region far away from the air conditioner, indicating that the presence or absence of the target object in the region close to the air conditioner cannot be detected through the second detection mode. In this case, the detection apparatus group may be switched from the second detection mode to the first detection mode, to detect the presence or absence of the target object within the predetermined range close to the air conditioner in the first detection mode with higher sensitivity. In response to detecting the target object, it is determined to control the air conditioner to enter a state corresponding to the person-proximity soft wind mode, and in response to detecting no target object, the air conditioner is controlled not to enter the state corresponding to the person-proximity soft wind mode.

[0105] In some scenarios, when the user selects the person-proximity soft wind mode, it indicates that the user needs the air outlet speed of the air conditioner to decrease as the user approaches, and the user may remain stationary in case of reaching the predetermined range of the air conditioner. In this case, the presence of the user with the static behavior within the predetermined range of the air conditioner cannot be detected using the second detection mode. Therefore, when the user selects the air conditioner to be in the person-proximity soft wind mode and the detection apparatus group is in the second detection mode, in response to the detection apparatus group detecting no target object within the predetermined range in the second detection mode, the detection apparatus group may be controlled to switch from the second detection mode to the first detection mode, thus, it may be determined the presence or absence of the target object within the predetermined range in the detection mode with higher sensitivity and situations where no target object is detected in case of the target object being within the predetermined range may be reduced.

[0106] In an example, in a case where the detection apparatus group is in the second detection mode to detect the state of the target object, in response to detecting no target object, the detection apparatus group is controlled to switch from the second detection mode to the first detection mode.

[0107] Generally, the air conditioner may detect the presence or absence of the target object dynamically moving indoors through the second detection mode of dynamic detection. When detecting the movement of the target object indoors, it indicates the presence of the target object. To ensure comfort experience of the target object, the air conditioner is controlled to be in a normal mode for normal operation, to cool or heat the target object normally. However, when detecting that the indoor target object has not moved through the second detection mode of dynamic detection, it indicates the presence of no target object indoors. When the target object stops moving indoors, a micro motion behavior in a state where the target object stops moving cannot be detected through the second detection mode of dynamic detection. Therefore, it is necessary to combine the first detection mode proposed in an embodiment of the present invention to detect the state of the target object, whether the state of the target object has changed may be detected through the first detection mode of static detection. In response to the state of the target object having changed, it is considered to that the target object has the micro motion behavior, indicating that the target object still exists indoors, thus avoiding missed detection of the target object.

[0108] For example, the micro motion of the target object cannot be detected through the second detection mode of dynamic detection, then the detection apparatus group may be controlled to be in the first detection mode. In the first detection mode, the sensitivity of the detection apparatus group may be increased to perform static detection on the micro motion of the target object indoors with higher sensitivity, thus avoiding missed detection of the target object. And the at least two detection apparatuses in the detection apparatus group alternatively performs the detection, therefore, the at least two detection apparatuses do not interfere with each other, ensuring a detection accuracy of the detection apparatus group. In the first detection mode, the detection apparatus group can detect the micro motion of the target object indoors in a highly sensitive, highly accurate, and wide detection range manner.

[0109] In an example, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the second mode. The air conditioner is maintained in a state corresponding to the second mode in response to detecting no target object.

[0110] When the user selects the second mode for the air conditioner to enter, it indicates that the user wants to be able to adjust the wind speed and the wind direction of the air conditioner in real time according to the position of the user. In this case, the state of the target object may be detected in the second detection mode with relatively low sensitivity. In response to detecting no moving target object indoors, the air conditioner may be controlled to keep in the state corresponding to the second mode. The state corresponding to the second mode indicates that the wind deflector and a wind speed level of the air conditioner are in a state required by the user.

[0111] In some scenarios, when the user has a distance of 100m away from home, the user may select the second mode for the air conditioner to enter remotely on a mobile phone of the user. When the detection apparatus group on the air conditioner detects that no target object is present indoors in the second detection mode, it may still control the air conditioner to enter the state corresponding to the second mode, such that when the user enters the home, the air conditioner can interact with the user according to the second mode set by the user. For example, in response to a mode set by the user being the wind blowing person mode, when the user enters the home, the air conditioner may immediately direct the output airflow to the user according to the wind blowing person mode set by the user, reducing a response duration of the wind blowing person mode and improving the user experience.

[0112] In an example, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the second mode. In response to detecting no target object, the wind deflector and / or the wind speed level of the air conditioner are maintained in a state when the target object is detected at a most recently time point.

[0113] When the user selects the second mode for the air conditioner to enter, it means that the user wants to be able to adjust the wind speed and the wind direction of the air conditioner in real time according to the position of the user. In this case, the state of the target object may be detected by the second detection mode with relatively low sensitivity. In response to detecting no moving target indoors, the wind deflector and / or the wind speed level of the air conditioner may be controlled to be in the state when the target object is detected at the most recently time point, until the movement of the target object is detected.

[0114] In some scenarios, when the user selects the wind blowing person mode for the air conditioner to enter, in response to the indoor user moves to a position A in a previous time point, the air conditioner may control its own wind deflector to direct towards the position A. In response to the user being at the position A and no longer moving in the next time point, the detection apparatus group on the air conditioner is in the second detection mode and cannot detect the target object. In this case, a direction of the wind deflector of the air conditioner may also direct towards the position A, to output airflow to the user at the position A, thus avoiding the direction of the wind deflector of the air conditioner from directing towards other positions and improving the user experience.

[0115] By means of the above technical solution, in a first aspect, the detection apparatus group is controlled to be in the second detection mode to detect the state of the target object in response to the indication of controlling the air conditioner to enter the second mode. When the user selects the second mode, it may further assist the control of the air conditioner in combination with the state of the target object, and the user experience may be improved. In a second aspect, when the user selects the air conditioner to be in the second mode, the detection apparatus group may be controlled to perform detection on the target object in the second detection mode. In the second detection mode, the at least two detection apparatuses in the detection apparatus group simultaneously perform the detection of the target object, which may expend the detection range. In a third aspect, the user selecting the second mode for the air conditioner may refer to that it is desired to adjust, by the air conditioner, the wind speed and the wind direction of the air conditioner according to the dynamic behavior of the user, and the dynamic behavior of the user can be detected by the second detection mode with relatively low sensitivity, thus, the dynamic behavior of the user obtained by directly using the second detection mode with relatively low sensitivity, for example, control for the state of the air conditioner in the second mode can be achieved based on the position of the user.
