[0028] Embodiments of the present application are described in detail below with reference to examples illustrated in the accompanying drawings, in which the same or similar components or elements are denoted throughout the drawings by the same or similar reference numerals, and the embodiments described below are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0029] In the related art, an air conditioning device detects a target object based on a radar mounted thereon, and in the detection process, is affected by the vibration of an internal fan and the swing of a guide vane, and is misdetected as having a target object, resulting in inaccurate detection. To solve this problem, in a case where it is detected that a target object exists in a first target area of a radar on an air conditioning device, it is determined whether a vibration source is started, and if the vibration source is started, since the vibration source can cause misrecognition, it is considered that the current detection result is inaccurate, and it is determined that no target object exists in the first target area, thereby improving the accuracy of target object detection.

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

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

[0032] Embodiments of the present application are exemplified by the target detection method being configured in a target detection device, which can be applied to any electronic device, so that the electronic device can perform a target detection function.

[0033] Among them, the electronic device can be any device with computing power, for example, it can be an air conditioning device and other hardware devices with air conditioning function, such as air conditioners, air purifiers, etc.

[0034] As shown in the Figure 1 The method can 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 started.

[0036] In the embodiments of this application, the air conditioning equipment is equipped with a radar sensor, such as a millimeter-wave radar or lidar. The radar's transmitting antenna transmits modulated electromagnetic waves, and the receiving antenna receives the electromagnetic wave signal reflected back from the target object, i.e., the echo signal. The echo signal is analyzed to determine information such as the distance to the target object. The target object is typically a person using the air conditioning equipment, but can also be a pet.

[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. The set distance is determined based on the distance of the vibration source installation position relative to the radar, for example, 0.6 meters. The vibration source includes a fan and / or air guide plate in the indoor unit of the air conditioning equipment. When the fan operates 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 radar echo signals detected in the first target area, and further resulting in the misidentification of the presence of a 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. 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 no target object exists 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 the target object does not actually exist 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 a target object in the first target area, resulting in inaccurate recognition results, and thus it can be judged that the target object does not exist 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 from the vibration source, and the detection result is considered accurate, that is, it is determined that the target object exists in the first target area.

[0041] In the target detection method of an embodiment of the present application, when it is detected that a target object exists within 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 no target object exists 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 in 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 within 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, so it 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 a first target signal strength threshold.

[0046] In the implementation of this 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: Acquire 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 through the receiving antenna, that is, the echo signal, and determines the strength of the echo signal 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 no target object exists in the first target area.

[0050] In this embodiment of the present application, the strength of the echo signal is compared with a first target signal strength threshold. If the strength of the echo signal is less than the first target signal strength threshold, it is determined that the target object does not exist in the first target area. Alternatively, if the strength of the echo signal is greater than the first target signal strength threshold, it is determined that the target object exists in the first target area.

[0051] In the target detection method of an 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, 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 goal of reducing the detection sensitivity and improving the accuracy of target object detection 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. The following embodiments are used to illustrate this.

[0053] Based on the above embodiments, Figure 3 The flowchart of another target detection method provided in the embodiment of the present application illustrates that when the vibration source includes a fan, the corresponding signal strength threshold is set for detection to improve the detection accuracy. Figure 3 As shown, the method comprises the following steps:

[0054] Step 301 : In response to detecting that a target object exists within a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0055] Among them, step 301 can refer to the relevant explanations in the above-mentioned embodiment, and the principle is the same, so it will not be repeated here.

[0056] Step 302: In response to the vibration source being activated, identify the vibration source.

[0057] In the embodiment of the present application, whether the vibration source is activated and which vibration source is activated can be determined based on 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.

[0058] Step 303 : In response to the vibration source being a fan and the fan operating at a target gear, determining that a signal strength threshold corresponding to the fan is a first signal strength threshold.

[0059] 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.

[0060] 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.

[0061] 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 based on the maximum speed and a set coefficient.

[0062] 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.

[0063] Step 304: Use the first signal strength threshold as the first target signal strength threshold.

[0064] 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 the 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.

[0065] Step 305: Acquire the strength of the detected radar echo signal.

[0066] Step 306: In response to the strength of the echo signal being less than the first target signal strength threshold, it is determined that no target object exists in the first target area.

[0067] Among them, step 305 and step 306 can refer to the relevant explanations in the above embodiments, and the principles are the same, so they will not be repeated here.

[0068] In the target detection method of the embodiments of the present application, in the case where it is detected that a target object exists in the first target area of the radar on the air conditioning device, it is determined whether the vibration source is started. If the vibration source is started, since the vibration source can cause misrecognition, the type of the vibration source is recognized, the first signal intensity threshold corresponding to the fan is taken as the first target signal intensity threshold, the signal intensity threshold of the first target area is increased to the first target signal intensity threshold, and based on the first target signal intensity threshold, it is confirmed that the current detection result is inaccurate, and it is determined that no target object exists in the first target area. By increasing the signal intensity threshold of the first target area, the detection sensitivity is reduced, and the accuracy of target object detection is improved.

[0069] Based on the above embodiments, Figure 4 Another flowchart of a target detection method provided by the embodiments of the present application is shown, which illustrates the case where the vibration source includes a deflector, and sets a corresponding signal intensity threshold for detection to improve detection accuracy. As shown in the figure, Figure 4 The method comprises the following steps:

[0070] Step 401, in response to detecting that a target object exists in the first target area of the radar on the air conditioning device, it is determined whether the vibration source is started.

[0071] In step 401, the relevant explanations in the foregoing embodiments can be referred to for explanation, and the principles are the same, which will not be described here again.

[0072] Step 402, in response to the vibration source being started, the vibration source is identified.

[0073] In the embodiments of the present application, according to the mode in which the air conditioning device operates, it can be determined whether the vibration source is started and which vibration source is started. For example, when the air conditioning device operates in the left-right air sweeping mode, the up-down air sweeping mode or mode switching is performed, it is considered that the deflector is started, and based on the mode in which it operates or the mode switching performed, the swinging direction of the deflector can be determined. The deflector swinging is considered to be the shaking of the deflector. Wherein, the mode switching is that the static position of the deflector in different modes is different, when the mode switching is performed, the deflector will swing to adjust to the set position corresponding to the mode switched to.

[0074] Step 403, in response to the vibration source being the deflector, the signal intensity threshold corresponding to the deflector is determined as the second signal intensity threshold.

[0075] In the embodiments of the present application, in the case where the vibration source is the deflector, the signal intensity threshold corresponding to the deflector is determined as the second signal intensity threshold, wherein the second signal intensity threshold and the first signal intensity threshold can be the same or different.

[0076] 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 detection accuracy in different scenarios.

[0077] 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.

[0078] 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.

[0079] 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 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 received echo signal is recorded. The maximum signal strength of the received echo signal is recorded, and the third signal strength threshold corresponding to the air guide plate swinging in the first set direction is determined based on the maximum signal strength. For example, the maximum signal strength 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 when the wind deflector swings in the first set direction can also be updated based on big data, thereby reducing detection sensitivity and improving detection accuracy.

[0080] 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 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 of the received echo signal is recorded. The third signal strength threshold corresponding to the air guide plate swinging in the second set direction is determined according to the maximum signal strength. For example, the maximum signal strength is I max3, the third signal intensity threshold value in this scenario is greater than I max3 Meanwhile, as the use time increases and the amount of collected data increases, the third signal intensity threshold value corresponding to the swing of the deflector in the first set direction can also be updated based on big data, reducing the detection sensitivity and improving the detection accuracy.

[0081] Step 404, the second signal intensity threshold value is taken as the first target signal intensity threshold value.

[0082] In the embodiments of the present application, the second signal intensity threshold value is taken as the first target signal intensity threshold value, so that in the case where the vibration source is started, the signal intensity threshold value corresponding to the vibration source is determined according to the different vibration sources, and in the case where the deflector swings in different set directions, the detection is realized by increasing the obtained second signal intensity threshold value, the detection sensitivity is reduced, the false detection interference caused by the deflector vibration is excluded, and the accuracy of the detection is improved.

[0083] Step 405, the intensity of the detected echo signal of the radar is obtained.

[0084] Step 406, in response to the intensity of the echo signal being less than the first target signal intensity threshold value, it is determined that there is no target object in the first target area.

[0085] Among them, step 405 and step 406 can refer to the related explanations in the foregoing embodiments, the principles are the same, and here will not be repeated.

[0086] It should be noted that in the case where the vibration source is not started, the high sensitivity is continued to be maintained, and the accuracy of the radar target detection is maintained.

[0087] In the target detection method of the embodiments of the present application, in the case where 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 will cause false recognition, the type of the vibration source is recognized, the second signal intensity threshold value corresponding to the deflector is taken as the first target signal intensity threshold value, based on the first target signal intensity threshold value, it is confirmed that the current detection result is inaccurate, it is determined that there is no target object in the first target area, and the signal intensity threshold value of the first target area is increased to reduce the detection sensitivity, and the accuracy of the target object detection is improved.

[0088] Based on the above embodiments, in the case where the vibration source includes the deflector and the fan, the corresponding signal intensity threshold value in this scenario can be determined based on the actually detected signal intensity of the radar, and the principles are similar, which are not limited in the embodiments.

[0089] 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 detection accuracy. Figure 5 As shown, the method comprises the following steps:

[0090] Step 501 : In response to detecting that a target object exists within a first target area of ​​a radar on an air conditioning device, determining whether a vibration source is activated.

[0091] Step 502: In response to the vibration source being activated, it is determined that no target object exists in the first target area.

[0092] Among them, step 501 and step 502 can refer to the relevant explanations in the above embodiments, and the principles are the same, so they will not be repeated here.

[0093] Step 503 : In response to the absence of the target object in the first target area, determining whether the air conditioning device is in a zone conditioning mode.

[0094] The second target area is outside the first target area. The first target area refers to the area within a set distance from the radar, for example, 0.6 meters. The set distance is determined based on the distance between the radar and the indoor unit, and the radar and the air deflector. The second target area is outside the set distance from the radar. The area adjustment mode is used to adjust the signal strength threshold in the second target area.

[0095] Step 504 : In response to starting the area adjustment mode, the signal strength threshold corresponding to the second target area to be detected is adjusted to the second target signal strength threshold.

[0096] 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.

[0097] Among them, when the second target area is different, the corresponding signal strength threshold is different, and the following describes the different situations respectively:

[0098] In one scenario, in response to the second target region being a dynamic region, the signal strength threshold of the second target region is adjusted to a fourth signal strength threshold, and the fourth signal strength threshold is taken as the second target signal strength threshold. As an example, the second target region can be at least one of a curtain region, a greenery region, and an activity region, i.e., the second target region includes an activity region, the activity region includes greenery and curtains, and the activity region includes autonomously movable objects such as a sweeping robot, and the greenery and curtains are objects that can move under the action of an external force, e.g., the greenery can sway in the wind, the curtains can sway in the wind, etc. Since in this region, dynamic objects can affect the radar detection result, compared with the uniform signal strength threshold in the related art, the signal strength threshold corresponding to this region needs to be increased to the fourth signal strength threshold, and by increasing the signal strength threshold, the sensitivity of radar detection in this region is reduced, thereby improving the detection result of the target object. The fourth signal strength threshold is determined based on actual measurement in the dynamic region, i.e., the fourth signal strength threshold is greater than the first signal strength threshold I max4 . max4 .

[0099] As an example, Figure 6 A region division schematic diagram of a living room is provided for the embodiments of the present application, as shown in Figure 6 The living room is divided into regions, and the coordinates of each region are given, such as the greenery region (x, y) (n≤x≤m; a≤y≤b). The activity region refers to Figure 6 the region outside the greenery region, the tea table region, the region occupied by the air conditioning device (air conditioner), and the sofa region.

[0100] As another example, Figure 7 A region division schematic diagram of a bedroom is provided for the embodiments of the present application, as shown in Figure 7 The bedroom is divided into regions, and the activity region is a dynamic region, which refers to Figure 7 the region outside the wardrobe region, the bed region, the desk region, and the region occupied by the air conditioner.

[0101] It should be noted that the division of the region can obtain the room boundary and the layout of the indoor furniture through means such as uploading a room layout photo by a user, reading room layout information by intelligent selection software, radar boundary detection adaptive learning, or uploading a house type diagram by an installation after-sales technician.

[0102] 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 target objects, and then perform intelligent wind control actions (such as wind following people, wind avoiding people, gentle wind when people are close, etc.), and fail to execute or interrupt the execution of unmanned mode (for example, entering energy saving or shutdown state when no one is in the state), resulting in the inability to perform related functions normally. Therefore, 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 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.

[0103] In the second scenario, in response to the second target area being a static area, the signal strength threshold of the second target area is adjusted to a fifth signal strength threshold, where 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.

[0104] As an example, Figure 6 As shown, the static area can be a coffee table area or a sofa area.

[0105] As another example, Figure 7 As shown, the static area can be a bed area, a desk area or a wardrobe area.

[0106] 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 a target object is generally stationary in the area.

[0107] 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 energy-saving or shutdown mode, and adjusting the threshold of the areas that are easy to miss detection, that is, static areas, such as sofa areas, bed areas, desk areas, etc., to reduce the signal strength threshold of the millimeter-wave radar echo signal in the area to the fifth signal strength threshold I5, so that it is not greater than the minimum intensity 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.

[0108] It should be noted that the fourth signal strength threshold and the fifth signal strength threshold can be updated and optimized according to the increase of the use time and the accumulation of data during the operation of the air conditioning device, to obtain the optimal threshold, so that the detection accuracy gradually increases with the increase of the use time of the air conditioner.

[0109] In step 505, the second target region is detected according to the second target signal strength threshold.

[0110] In order to improve the accuracy of detection, in the case that the second target region is a dynamic region, the second target signal strength threshold is the fourth signal strength threshold. Since there is a possibility of false detection in this region, the echo signal of the radar can be obtained based on a set detection period, for example, 10 seconds. If the signal strength of the echo signal detected in a plurality of continuous detection periods is greater than the fourth signal strength threshold, it is determined that there is a target object in the second target region, for example, a person, to improve the accuracy of detection.

[0111] In order to improve the accuracy of detection, in the case that the second target region is a static region, the second target signal strength threshold is the fifth signal strength threshold. Since there is a case of missed detection in this region, if the signal strength of the echo signal of the radar detected based on one detection is greater than the fifth signal strength threshold, it is determined that there is a target object in the second target region.

[0112] In the target detection method of the embodiments of the present application, in response to the fact that there is no target object in the first target region, it is determined whether the air conditioning device is in the region adjustment mode. In response to the fact that the region adjustment mode is started, the signal strength threshold corresponding to the second target region to be detected is adjusted to the second target signal strength threshold.
