[0028] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] In the related art, air conditioning equipment detects target objects based on the radar on board. During the detection process, it will be affected by the vibration of the internal fan and the swing of the wind guide plate, and it will be mistakenly detected as a target object, resulting in inaccurate detection. In order to solve this problem, when it is detected that there is a target object in the first target area of ​​the radar on the air conditioning equipment, it is determined whether the vibration source is started. If the vibration source is started, since the vibration source may cause misidentification, it is considered that the current detection result is inaccurate, and it is determined that there is no target object in the first target area, thereby improving the accuracy of target object detection.

[0030] The target detection method, device, electronic device and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.

[0031] Figure 1 A flowchart of a target detection method provided in an embodiment of the present application.

[0032] The embodiment of the present application takes the target detection method being configured in a target detection device as an example. The target detection device can be applied to any electronic device so that the electronic device can perform a target detection function.

[0033] The electronic device may be any device with computing capability, for example, an air conditioning device or other hardware device with air conditioning function, such as an air conditioner, an air purifier, etc.

[0034] like Figure 1 As shown, the method may include the following steps:

[0035] Step 101 : in response to detecting that a target object exists in a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0036] In the embodiment of the present application, the air conditioning equipment is equipped with a radar sensor, such as a millimeter wave radar, a laser radar, etc., which transmits modulated electromagnetic waves through the radar's transmitting antenna, and then receives the electromagnetic wave signal reflected back by the target object through the receiving antenna, that is, the echo signal, and determines the distance to the target object and other information by analyzing the echo signal. The target object is usually a person using the air conditioning equipment, but can also be a pet at home.

[0037] In the embodiment of the present application, the first target area refers to an area within a set distance relative to the radar, that is, an area within a set distance from the radar, and the set distance is determined based on the distance of the installation position of the vibration source relative to the radar, for example, 0.6 meters. The vibration source includes a fan and / or an air guide plate in the indoor unit of the air conditioning equipment, wherein when the fan is running at a corresponding speed, the vibration and noise will interfere with the radar detection; when the air guide plate swings in a set direction, it will also interfere with the radar detection, resulting in inaccurate echo signals of the radar detected in the first target area, and further resulting in the misidentification of the existence of the target object in the first target area. Therefore, when the target object is detected in the first target area of ​​the radar on the air conditioning equipment, it is necessary to determine whether the vibration source is activated, and whether the vibration source is activated is related to whether the detection result is accurate.

[0038] Step 102: In response to the vibration source being activated, determining that there is no target object in the first target area.

[0039] In one implementation of the embodiment of the present application, when the vibration source is activated and the presence of a target object is detected in the first target area, it is considered that there is actually no target object in the first target area. This is because in the first target area, the electromagnetic wave signal emitted by the radar will be affected by the vibration source, resulting in a deviation in the value of the reflected echo signal, thereby misidentifying the presence of the target object in the first target area, resulting in inaccurate recognition results, and thus it can be judged that there is no target object in the first target area.

[0040] It should be noted that if the vibration source is not activated, it is considered that there is no influence of the vibration source, and the detection result is considered accurate, that is, it is determined that there is a target object in the first target area.

[0041] In the target detection method of the embodiment of the present application, when it is detected that there is a target object in the first target area of ​​the radar on the air-conditioning equipment, it is determined whether the vibration source is activated. If the vibration source is activated, since the vibration source may cause misidentification, the current detection result is considered inaccurate, and it is determined that there is no target object in the first target area, thereby improving the accuracy of target object detection.

[0042] Based on the above embodiments, Figure 2The flowchart of another target detection method provided by the embodiment of the present application illustrates that when the vibration source is activated, the accuracy of target object detection can be improved by increasing the signal strength threshold corresponding to the first target area. Figure 2 As shown, the method comprises the following steps:

[0043] Step 201 : in response to detecting that a target object exists in a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0044] Among them, step 201 can refer to the relevant explanations in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0045] Step 202: In response to the vibration source being activated, increasing the signal strength threshold of the first target area to the first target signal strength threshold.

[0046] In the implementation of the present application, when the vibration source is started, the vibration of the vibration source will cause an increase in the echo signal of the radar received within the range of the first target area, resulting in inaccuracy. Therefore, the signal strength threshold of the first target area is increased to the first target signal strength threshold. By raising the signal strength threshold, the detection accuracy is increased.

[0047] Step 203, obtaining the strength of the detected radar echo signal.

[0048] In the embodiment of the present application, the transmitting antenna of the radar sends modulated electromagnetic waves, and then receives the electromagnetic wave signal reflected by the target object, that is, the echo signal, through the receiving antenna, and the strength of the echo signal is determined by analyzing the echo signal.

[0049] Step 204: In response to the strength of the echo signal being less than the first target signal strength threshold, it is determined that there is no target object in the first target area.

[0050] In the embodiment of the present application, the strength of the echo signal is compared with the first target signal strength. If the strength of the echo signal is less than the first target signal strength threshold, it is determined that there is no target object in the first target area. In addition, if the strength of the echo signal is greater than the first target signal strength threshold, it is determined that there is a target object in the first target area.

[0051] In the target detection method of the embodiment of the present application, when it is detected that there is a target object in the first target area of ​​the radar on the air-conditioning equipment, it is determined whether the vibration source is started. If the vibration source is started, the signal strength threshold of the first target area is increased to the first target signal strength threshold because the vibration source may cause misidentification. Based on the first target signal strength threshold, it is confirmed that the current detection result is inaccurate, and it is determined that there is no target object in the first target area. This achieves the improvement of the accuracy of target object detection by reducing the detection sensitivity by raising the signal strength threshold of the first target area.

[0052] The above embodiments illustrate that when the vibration source is activated, misidentification can be reduced by increasing the threshold of the first target area, and setting different signal strength thresholds for different vibration sources can further improve the accuracy of target object detection, which is explained below using embodiments.

[0053] Based on the above embodiments, Figure 3 A flow chart of another target detection method provided in an embodiment of the present application illustrates that when the vibration source includes a fan, a corresponding signal strength threshold is set for detection to improve detection accuracy.

[0054] like Figure 3 As shown, the method comprises the following steps:

[0055] Step 301 : in response to detecting that a target object exists in a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0056] Among them, step 301 can refer to the relevant explanations in the above-mentioned embodiment, and the principle is the same, which will not be repeated here.

[0057] Step 302, in response to the vibration source being activated, identifying the vibration source.

[0058] In the embodiment of the present application, whether the vibration source is activated and which vibration source is activated can be determined according to the operating mode of the air conditioning device. For example, if the air conditioning device is operating at a set wind speed, it means that the fan is activated, and the gear of the fan operation can be determined.

[0059] Step 303: In response to the vibration source being a fan and the fan operating at a target gear position, determining that a signal strength threshold corresponding to the fan is a first signal strength threshold.

[0060] Among them, the fan speed corresponding to the target gear is greater than the set speed. Since the fan operates at a low wind speed, the vibration is small and the interference caused is small. Therefore, when the fan operates at a low wind speed, the signal strength threshold is not increased.

[0061] In the embodiment of the present application, when the vibration source is a fan and the fan is running at a target gear, the signal strength threshold corresponding to the fan is determined to be the first signal strength threshold.

[0062] Among them, as an implementation method for determining the first signal strength threshold, the maximum speed of the fan is determined, and the first signal strength threshold is determined according to the maximum speed and the set coefficient.

[0063] As an implementation method, according to formula I max1 =k*N max (k>0), it can be determined that when the fan is running at the highest speed, the maximum value of the radar echo signal is I max1 , thus, it can be determined that the first signal strength threshold is greater than I max1 The specific value can be set based on the detection accuracy. max is the maximum speed of the fan, and K is the setting coefficient.

[0064] Step 304: Use the first signal strength threshold as the first target signal strength threshold.

[0065] In an embodiment of the present application, the first signal strength threshold is used as the first target signal strength threshold, so that when the vibration source is started, the signal strength threshold corresponding to the vibration source is determined according to different vibration sources. When the fan is running at high speed, detection is performed by increasing the obtained first signal strength threshold, thereby reducing the detection sensitivity, eliminating the false detection interference caused by the fan vibration, and improving the detection accuracy.

[0066] Step 305: Acquire the strength of the detected radar echo signal.

[0067] Step 306: In response to the strength of the echo signal being less than the first target signal strength threshold, it is determined that there is no target object in the first target area.

[0068] Among them, step 305 and step 306 can refer to the relevant explanations in the aforementioned embodiments, and the principles are the same, so they will not be repeated here.

[0069] In the target detection method of the embodiment of the present application, when it is detected that there is a target object in the first target area of ​​the radar on the air-conditioning equipment, it is determined whether the vibration source is started. If the vibration source is started, the type of vibration source is identified because the vibration source may cause misidentification, and the first signal strength threshold corresponding to the fan is used as the first target signal strength threshold, and the signal strength threshold of the first target area is increased to the first target signal strength threshold. Based on the first target signal strength threshold, it is confirmed that the current detection result is inaccurate, and it is determined that there is no target object in the first target area. This achieves the improvement of the accuracy of target object detection by reducing the detection sensitivity by raising the signal strength threshold of the first target area.

[0070] Based on the above embodiments, Figure 4 A flow chart of another target detection method provided in an embodiment of the present application illustrates that when the vibration source includes a windshield, a corresponding signal strength threshold is set for detection to improve detection accuracy. Figure 4 As shown, the method comprises the following steps:

[0071] Step 401 : in response to detecting that a target object exists in a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0072] Among them, step 401 can refer to the relevant explanations in the above-mentioned embodiments, and the principle is the same, which will not be repeated here.

[0073] Step 402, in response to the vibration source being activated, identifying the vibration source.

[0074] In the embodiment of the present application, it can be determined whether the vibration source is activated and which vibration source is activated according to the operating mode of the air conditioning equipment. For example, when the air conditioning equipment is operating in the left and right sweeping mode, the up and down sweeping mode, or when the mode is switched, it is considered that the wind shield is activated, and based on the operating mode or the mode switching performed, the swing direction of the wind shield can be determined, and the swinging of the wind shield is considered to be vibrating the wind guide plate. Among them, mode switching means that the static position of the wind shield is different in different modes. When the mode is switched, the wind shield will swing to adjust to the set position corresponding to the switched mode.

[0075] Step 403: In response to the vibration source being the wind deflector, determining that the signal strength threshold corresponding to the wind deflector is a second signal strength threshold.

[0076] In an embodiment of the present application, when the vibration source is an air guide plate, the signal strength threshold corresponding to the air guide plate is determined to be the second signal strength threshold, wherein the second signal strength threshold and the first signal strength threshold may be the same or different.

[0077] Since the wind deflector may swing in different directions, different signal strength thresholds may be set when the wind deflector swings in different directions to improve the detection accuracy in different scenarios.

[0078] As an implementation method, the swing direction of the air guide plate is determined, and the third signal strength threshold corresponding to the swing direction is determined according to the swing direction of the air guide plate. The third signal strength threshold corresponding to the swing direction is used as the second signal strength threshold. That is, when the air guide plate is operating in different swing directions, the third signal strength threshold corresponding to the swing direction can be set to improve the accuracy of the air guide plate when it swings in different directions.

[0079] Among them, the method for determining the third signal strength threshold corresponding to the swing direction, as an implementation method, determines the maximum signal strength of the received echo signal in response to the wind guide plate swinging in the corresponding swing direction, and determines the third signal strength threshold corresponding to the swing direction based on the maximum signal strength of the echo signal corresponding to the swing direction.

[0080] In one scenario, the air guide plate swings in a first set direction, and the first set direction is, for example, left-right swinging. By querying the operating mode of the air conditioning device, it can be determined that the current air conditioning device is operating in the left-right wind sweeping mode, thereby determining that the air guide plate is swinging left-right, that is, determining the third signal strength threshold corresponding to the left-right swinging, wherein the third signal strength threshold corresponding to the left-right swinging is predetermined. As an implementation method, the air guide plate is set to swing in the first set direction, and the strength value of the echo signal is received, and the maximum signal strength value of the received echo signal is recorded, and the third signal strength threshold corresponding to the swing of the air guide plate in the first set direction is determined according to the maximum signal strength value. For example, the maximum signal strength value is I max2 , the third signal strength threshold in this scenario is greater than I max2 At the same time, as the usage time increases and the amount of collected data increases, the third signal strength threshold corresponding to the wind deflector swinging in the first set direction can also be updated based on big data to reduce detection sensitivity and improve detection accuracy.

[0081] In the second scenario, the air guide plate swings in the second set direction, and the second set direction is, for example, up and down swinging. By querying the operating mode of the air conditioning equipment, it can be determined that the current air conditioning equipment is operating in the up and down wind sweeping mode, thereby determining that the air guide plate is swinging up and down, that is, determining the third signal strength threshold corresponding to the up and down swinging, wherein the third signal strength threshold corresponding to the up and down swinging is predetermined. As an implementation method, the air guide plate is set to swing in the second set direction, and the strength value of the echo signal is received, and the maximum signal strength value of the received echo signal is recorded, and the third signal strength threshold corresponding to the swing of the air guide plate in the second set direction is determined according to the maximum signal strength value. For example, the maximum signal strength value is I max3, the third signal strength threshold in this scenario is greater than I max3 At the same time, as the usage time increases and the amount of collected data increases, the third signal strength threshold corresponding to the wind deflector swinging in the first set direction can also be updated based on big data to reduce detection sensitivity and improve detection accuracy.

[0082] Step 404: Use the second signal strength threshold as the first target signal strength threshold.

[0083] In an embodiment of the present application, the second signal strength threshold is used as the first target signal strength threshold, so that when the vibration source is started, the signal strength threshold corresponding to the vibration source is determined according to different vibration sources, so that when the air guide plate swings in different set directions, detection is performed by increasing the obtained second signal strength threshold, thereby reducing the detection sensitivity, eliminating the false detection interference caused by the fan vibration, and improving the detection accuracy.

[0084] Step 405: Acquire the strength of the detected radar echo signal.

[0085] Step 406: In response to the strength of the echo signal being less than the first target signal strength threshold, it is determined that there is no target object in the first target area.

[0086] Among them, step 405 and step 406 can refer to the relevant explanations in the above-mentioned embodiments, and the principles are the same, so they will not be repeated here.

[0087] It should be noted that when the vibration source is not activated, the radar continues to maintain high sensitivity and the accuracy of target detection.

[0088] In the target detection method of the embodiment of the present application, when it is detected that there is a target object in the first target area of ​​the radar on the air-conditioning equipment, it is determined whether the vibration source is started. If the vibration source is started, the type of vibration source is identified because the vibration source may cause misidentification, and the second signal strength threshold corresponding to the air guide plate is used as the first target signal strength threshold. Based on the first target signal strength threshold, it is confirmed that the current detection result is inaccurate, and it is determined that there is no target object in the first target area. This achieves the improvement of the accuracy of target object detection by reducing the detection sensitivity by raising the signal strength threshold of the first target area.

[0089] Based on the above embodiment, when the vibration source includes a wind shield and a fan, the corresponding signal strength threshold in the scenario can be determined based on the signal strength of the radar actually detected. The principle is similar and is not limited in this embodiment.

[0090] Based on the above embodiments, Figure 5The flowchart of another target detection method provided in the embodiment of the present application specifically illustrates how to detect a second target area outside the first target area to improve the detection accuracy. Figure 5 As shown, the method comprises the following steps:

[0091] Step 501 : in response to detecting that a target object exists in a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0092] Step 502: In response to the vibration source being activated, determining that there is no target object in the first target area.

[0093] Among them, step 501 and step 502 can refer to the relevant explanations in the aforementioned embodiments, and the principles are the same, so they will not be repeated here.

[0094] Step 503 : In response to the absence of the target object in the first target area, determining whether the air conditioning device turns on the area conditioning mode.

[0095] The second target area is outside the first target area. The first target area refers to the area within the set distance from the radar, for example, the set distance is 0.6 meters, and the set distance is determined based on the distance between the radar and the internal unit, and the radar and the wind deflector. The second target area is the area outside the set distance from the radar. The area adjustment mode is used to adjust the signal strength threshold in the second target area.

[0096] Step 504: in response to starting the area adjustment mode, adjusting the signal strength threshold corresponding to the second target area to be detected to the second target signal strength threshold.

[0097] In the related art, for the space where air conditioning equipment is used, a unified signal strength threshold is usually used for target detection in all areas. In order to improve the accuracy of detection, as an implementation method, a regional adjustment mode is set. If the air conditioning equipment responds to the user's setting operation and turns on the regional adjustment mode, the signal strength threshold corresponding to the second target area to be detected is adjusted to the second target signal strength threshold, so that the corresponding signal strength threshold is used for different second target areas to detect target objects, so as to adjust the detection sensitivity and improve the detection accuracy.

[0098] When the second target area is different, the corresponding signal strength threshold is different, and the following describes the different situations respectively:

[0099] In one scenario, in response to the second target area being a dynamic area, the signal strength threshold of the second target area is adjusted to a fourth signal strength threshold, and the fourth signal strength threshold is used as the second target signal strength threshold. As an example, the second target area can be at least one of a curtain area, a green plant area, and an activity area, that is, the second target area includes an activity area, and the activity area includes green plants and curtains. The activity area includes objects that can move autonomously, such as a sweeping robot. Green plants and curtains are objects that can be moved by external forces. For example, green plants can swing with the wind, and curtains can swing with the wind. Because dynamic objects in this area will affect the radar detection results, relative to the unified signal strength threshold in the related art, it is necessary to increase the signal strength threshold corresponding to the area to the fourth signal strength threshold. By increasing the signal strength threshold, the sensitivity of radar detection in this area is reduced, thereby improving the detection results of the target object. Among them, the fourth signal strength threshold is based on the maximum signal strength I determined by actual measurement in the dynamic area. max4 Determined, that is, the fourth signal strength threshold is greater than I max4 .

[0100] As an example, Figure 6 A schematic diagram of the area division of an object provided in an embodiment of the present application, such as Figure 6 As shown, the object is divided into regions, where the dynamic region can be a green plant region or an activity region, and the coordinate range of each region is given, such as a green plant region (x, y) (n≤x≤m; a≤y≤b). The activity region refers to Figure 6 The area outside the green plant area, coffee table area, air conditioning equipment (air conditioner) and the sofa area.

[0101] As another example, Figure 7 A schematic diagram of the area division of a bedroom provided in an embodiment of the present application, such as Figure 7 As shown, the bedroom is divided into zones. The dynamic zone can be the activity zone. The activity zone refers to Figure 7 The area outside the wardrobe area, window area, desk area and air conditioner area.

[0102] It should be noted that the division of areas can be achieved by users uploading room layout photos, smart selection software reading room layout information, radar boundary detection adaptive learning, or after-sales installation technicians uploading floor plans to obtain room boundaries and indoor furniture layouts.

[0103] In the first scenario, in order to avoid the wind blowing green plants, curtains shaking, sweeping robots, etc., the millimeter-wave radar may mistakenly detect the presence of a target object, and then perform intelligent wind control actions (such as wind following people, wind avoiding people, gentle wind near people, etc.), and fail to execute or interrupt the execution of unmanned mode (for example, entering energy saving or shutdown state when unmanned), resulting in the inability to implement related functions normally, so it is necessary to adjust the threshold of dynamic areas (such as green plant areas, curtain areas, activity areas, etc.), and increase the signal strength threshold of the millimeter-wave radar echo signal in this area to the fourth signal strength threshold I4, so that it is greater than the maximum echo signal strength I of the interference source. max4 , that is, I4>I max4 , thereby reducing the radar detection sensitivity in the area and improving detection accuracy.

[0104] In the second scenario, in response to the second target area being a static area, the signal strength threshold of the second detection area is adjusted to a fifth signal strength threshold, wherein the fifth signal strength threshold is less than the fourth signal strength threshold, and the fifth signal strength threshold is used as the second target signal strength threshold.

[0105] As an example, Figure 6 As shown, the static area can be a coffee table area or a sofa area.

[0106] As another example, Figure 7 As shown, the static area can be a window area, a desk area or a wardrobe area.

[0107] It should be noted that in other scenarios, the division of static areas and Figure 6 and Figure 7 It may be different, a static area generally includes static objects, and the target object is generally at rest in the area.

[0108] In the second scenario, in order to prevent people from sitting or sleeping in front of a desk, sofa, bed, etc., the millimeter-wave radar may not detect the presence of the target object, thereby performing an unmanned action or mode, such as entering a power saving or shutdown mode, and adjusting the threshold of the areas that are easy to miss detection, that is, static areas, such as the sofa area, bed area, desk area, etc., to reduce the signal strength threshold of the echo signal of the millimeter-wave radar in the area to the fifth signal strength threshold I5, so that it is not greater than the minimum strength I of the echo signal when the human body is sitting or resting. min , that is, I5≤I min , thereby improving the radar detection sensitivity in the area, improving the accuracy of detection in the area, and avoiding misidentification.

[0109] It should be noted that the fourth signal strength threshold and the fifth signal strength threshold can be updated and optimized during the operation of the air conditioning equipment according to the increase in usage time and the accumulation of data to obtain the optimal threshold, so that the detection accuracy gradually improves with the increase in the usage time of the air conditioner.

[0110] Step 505: Detect the target object in the second target area according to the second target signal strength threshold.

[0111] In order to improve the accuracy of detection, when the second target area is a dynamic area, the second target signal strength threshold is the fourth signal strength threshold. Since there is a possibility of false detection in this area, the radar echo signal can be acquired based on the set detection period, where the period is, for example, 10 seconds. If the signal strength of the echo signal detected in multiple consecutive detection periods is greater than the fourth signal strength threshold, it is determined that there is a target object in the second target area, the target object is, for example, a person, to improve the accuracy of detection.

[0112] In order to improve the accuracy of detection, when the second target area is a static area, the second target signal strength threshold is the fifth signal strength threshold. Since there is a missed detection in this area, if the signal strength of the echo signal based on the radar detected once is greater than the fifth signal strength threshold, it is determined that there is a target object in the second target area.

[0113] In the target detection method of the embodiment of the present application, in response to the absence of a target object in a first target area, it is determined whether the air-conditioning equipment turns on the zone adjustment mode. In response to turning on the zone adjustment mode, the signal strength threshold corresponding to the second target area to be detected is adjusted to the second target signal strength threshold. The second target area is outside the first target area, and target object detection is performed on the second target area according to the second target signal strength threshold.
