[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] The object detection method provided by this application can be applied to the application environment as Figure 1 shown.

[0057] Figure 1 A device control system is shown. As shown in the figure, the device control system may include a terminal device 100, a gateway 200, an Internet of Things device 300 deployed in the gateway 200, a server 400, and a router 500. Among them, the gateway 200 can be an intelligent gateway for smart home control, and can implement functions such as system data collection, data transmission, and linkage control. The gateway 200 can also interact with products such as cloud servers and intelligent interaction terminals through wireless means.

[0058] The terminal device 100 can be any device with communication and storage functions, such as: desktop computers, laptop computers, tablet computers, smart phones, or other intelligent communication devices that can implement network connections, which are not limited here.

[0059] The Internet of Things device 300 can be a clothes dryer with sensing functions, intelligent lamps, intelligent printers, intelligent fax machines, intelligent cameras, intelligent air conditioners, intelligent TVs, intelligent refrigerators, or a radar module, a human body sensor, a door and window sensor, a temperature and humidity sensor, a water immersion sensor, a natural gas alarm, a smoke alarm, a wall switch, a wall socket, a wireless switch, a wireless wall sticker switch, a magic cube controller, a curtain motor, etc. that are equipped with a communication module (such as a ZIGBEE module, a WIFI module, a Bluetooth communication module, etc.) and have sensing functions.

[0060] Among them, the Internet of Things device 300 can detect target objects in the target space, and after obtaining the detection signal, process the detection signal to obtain a control strategy, and then execute the control strategy.

[0061] The server 400 can be a local server, a cloud server, etc. The specific type of server can be not limited in the embodiments of this application. The Internet of Things devices 300 and the gateway 200 set in different spatial regions can all communicate and connect with the same server 400 through the network.

[0062] A network connection is established between the terminal device 100 and the gateway 200. In one implementation, a network connection is established between the terminal device 100 and the gateway 200 through 2G / 3G / 4G / 5G, Wi-Fi, etc. Through this network connection, it interacts with the gateway 200, so that the user can control the devices connected to the gateway 200 through this terminal device 100 to perform corresponding actions.

[0063] Optionally, the terminal device 100 is equipped with a client that can manage IoT devices. The client can be an application client (such as a mobile APP), a web client, or a mini-program, etc., and there is no limitation on it.

[0064] Both gateway 200 and terminal device 100 can connect to router 500 and access the network through router 500. Router 500 can connect to server 400 via wired or wireless communication. For example, gateway 200 and terminal device 100 can store the acquired information in cloud server 400. Optionally, terminal device 100 can also establish a network connection with cloud server 400 via 2G / 3G / 4G / 5G, Wi-Fi, etc., thereby obtaining data sent by cloud server 400.

[0065] In some implementations, the IoT device 300 can send the acquired detection signal to the terminal device 100 or the server 400. The terminal device 100 or the server 400 processes the detection signal to obtain a control strategy and obtains a control command based on the control strategy, and then sends it to the IoT device 300 so that the IoT device 300 executes the control command.

[0066] Exemplary methods

[0067] Please see Figure 2 , Figure 2 The flowchart shown is a target detection method according to an embodiment of this application. The method can be executed by an electronic device, for example, the electronic device may be... Figure 1 The server in the middle can also be Figure 1 The terminal device in the process can also be an IoT device with processing capabilities, such as a clothes dryer. Specifically, the method may include the following steps:

[0068] Step S201: If a detection signal is received, the target area where the object to be detected is located is determined based on the detection signal. The detection signal represents the signal returned after the object to be detected is detected within the detection area of ​​the device.

[0069] The detection area can refer to the physical space to be monitored. This physical space can be a closed space (such as the interior space of a home or the interior space of a public area such as a shopping mall or train station) or an open space (such as a square). Correspondingly, the detection signal can refer to the signal fed back after a specific detection signal detects the object to be monitored within the detection area; this application does not exhaustively list all such signals.

[0070] In one exemplary embodiment of this application, the detection signal can specifically be the echo signal received by the radar module of the smart clothes dryer in the smart home system after it emits a signal, which is then blocked by the object to be detected. In practice, millimeter waves can be continuously emitted by the transmitting antenna inside the radar module of the smart clothes dryer, and the receiving antenna can receive the echo signal. The echo signal fed back within a set detection area is used as the detection signal. When a detection signal is received, it indicates the presence of a suspicious object, i.e., the object to be detected, within the current detection area. The distance between the object to be detected and the receiving antenna can then be determined based on the detection signal, and subsequently, the target area where the object to be detected is located can be determined based on this distance.

[0071] The target area can be a drying area centered on the radar module of the smart clothes dryer, divided according to different echo ranges.

[0072] Step S202: Determine the target sensitivity threshold corresponding to the target area based on the target area.

[0073] During implementation, a correspondence between location regions and sensitivity thresholds can be established in advance. That is, different sensitivity thresholds can be determined for different location regions. Based on this, after dividing the detection area into location regions, the location region where the object to be detected is located can be determined as the target region, and then the sensitivity threshold corresponding to the location region of the object to be detected can be determined as the target sensitivity threshold corresponding to the target object, so as to more accurately identify the object to be detected.

[0074] Step S203: Adjust the operating mode of the device according to the detection signal and the target sensitivity threshold.

[0075] During implementation, the detection signal and target sensitivity threshold can be used to determine whether the object to be detected is the target object. For example, when the device is a smart clothes drying rack, the detection area is the clothes drying area. It can detect whether the object appearing in the clothes drying area is a protected object (target object), such as a person or animal. If the detection signal and target sensitivity threshold determine that the object in the clothes drying area is a person, the working mode of the smart clothes drying rack can be adjusted to avoid harming the target object during disinfection. For example, if the smart clothes drying rack uses ultraviolet lamps to disinfect the clothes drying area, after determining that the object to be detected is the target object, the working mode of the device can be adjusted, such as turning off the ultraviolet lamps, to avoid harm to the target object from ultraviolet radiation.

[0076] In this embodiment, during the implementation of the target detection method, if a detection signal is received, it indicates that the object to be detected has been detected. The target area where the object is located can then be determined based on the detection signal. The detection signal represents the signal returned after the object is detected within the detection area of ​​the device. Furthermore, based on the target area, a target sensitivity threshold corresponding to that area is determined. Then, based on the detection signal and the target sensitivity threshold, the device's operating mode is adjusted. Thus, after dividing the detection area into different regions, the target area where the object to be detected is located and its corresponding target sensitivity threshold can be determined using the different sensitivity thresholds corresponding to different regions. Subsequently, based on different objects to be detected within the detection area and their locations, different operating modes of the device are adjusted, effectively improving the precise and intelligent control of the device.

[0077] In some embodiments, to further ensure the accuracy of detection, the detection area may include at least two sub-regions corresponding to different sub-sensitivity thresholds. Accordingly, when determining the target area where the object to be detected is located based on the detection signal, the sub-region where the object to be detected is currently located can be determined based on the detection signal, and the sub-region can be designated as the target area.

[0078] During implementation, the detection area can be subdivided according to the target object. For example, if the detection area is a clothes-drying area, it can be divided into three sub-areas as follows: the area 1.8-2.4m from the radar module of the smart clothes dryer is designated as the pet-prone sub-area; the area 0.8-1.8m from the radar module is designated as the adult-prone sub-area; and the area 0-0.8m from the radar module is designated as the main clothes-drying sub-area, which is easily affected by wind or motor vibration. In this way, based on the detection signal, the location of the object to be detected within the detection area can be determined first, and then the sub-area in which the object is located can be identified. After identifying the sub-area, the identity of the object can be preliminarily determined. For example, if the sub-area in which the object is located is the pet-prone sub-area, then the object can be preliminarily identified as a pet, and the pet-prone sub-area can be designated as the target area.

[0079] Similarly, when determining the target sensitivity threshold corresponding to the target area, we can determine the sub-sensitivity threshold corresponding to the sub-area where the object to be detected is currently located, and set this sub-sensitivity threshold as the target sensitivity threshold. That is, if a sub-area where pets are likely to appear is determined as the target area, then the sub-sensitivity threshold corresponding to this sub-area can be determined and set as the target sensitivity threshold. In this way, not only is the detection area divided, but different sub-sensitivity thresholds are also set for different sub-areas. After detecting the presence of an object to be detected, the target sensitivity threshold corresponding to the location of the object can be clearly defined, providing a theoretical basis for further verification of the object's identity.

[0080] In some embodiments, the sub-sensitivity threshold is determined by a sub-region corresponding to the sub-sensitivity threshold, and the distance between the sub-region and the device is negatively correlated with the sub-sensitivity threshold corresponding to the sub-region.

[0081] In this context, the greater the distance between the sub-region and the device, the weaker the detection signal. Therefore, a smaller sensitivity threshold is needed for the signal strength to exceed the sub-sensitivity threshold, indicating that a target object has been detected in that sub-region. A smaller sub-sensitivity threshold generally indicates higher device sensitivity; conversely, a larger sub-sensitivity threshold makes it less likely for the detection signal strength to exceed the threshold, indicating lower device sensitivity.

[0082] In practice, sub-regions can be divided according to the different types of target objects appearing in the detection area. Similarly, the sub-sensitivity threshold corresponding to each sub-region can be determined according to the type of target object.

[0083] In practical implementation, taking a smart clothes drying rack as an example, since most smart clothes drying racks are installed on the roof indoors, at a height of 2.6-2.8m above the ground, the transmission distance of the radar module of the smart clothes drying rack can be set at 2.4m. Then, with the location of the radar module as the starting point, the clothes drying area can be divided into 3 sub-areas.

[0084] The first sub-region can be the area where clothes are being dried, and the range of the area can be 0-0.8m away from the radar module. Since this area is easily affected by factors such as wind or vibration of the clothes dryer motor, this target area can be defined as an area prone to misjudgment. Accordingly, its detection sensitivity should be low, and the corresponding sub-sensitivity threshold needs to be adjusted to a high level to avoid misjudging the shaking of clothes due to the low factor sensitivity threshold.

[0085] The second sub-region can be the core detection area, and its range can be set to 0.8-1.8m away from the radar module. Adults are more likely to appear in this area, and correspondingly, this area can be defined as the first main detection area. Since the distance from the radar module is farther than that of the area prone to misjudgment, its detection sensitivity needs to be improved, and the corresponding sub-sensitivity threshold should also be reduced. That is, the sub-sensitivity threshold corresponding to the first main detection area should be lower than that corresponding to the sub-sensitivity threshold of the area prone to misjudgment, so as to more accurately identify the human body appearing in this area.

[0086] The third sub-region can be an area closer to the ground, with a range of 1.8-2.4m from the radar module. Children or pets are more likely to appear in this area, and this area can be defined as the second main detection area. Since the distance from the radar module is greater than that of the first main detection area, its detection sensitivity needs to be increased accordingly, and the corresponding sub-sensitivity threshold needs to be reduced. That is, the sub-sensitivity threshold corresponding to the second main detection area should be lower than that corresponding to the first main detection area, so as to more accurately identify children or pets appearing in this area.

[0087] During the target detection process, when the object to be detected appears in any of the three sub-regions mentioned above, the smart clothes drying machine can determine the sub-region where the object is located based on the received detection signal, designate the sub-region as the target region, and determine the sensitivity threshold corresponding to the sub-region as the target sensitivity threshold corresponding to the target region, so as to ensure the accuracy of subsequent detection.

[0088] It should be understood that the number of sub-regions and the corresponding sub-sensitivity threshold for each sub-region can be set according to actual needs, and there is no limitation here.

[0089] In some embodiments, in order to accurately determine the sub-region where the object to be detected is located, when determining the sub-region where the object to be detected is currently located based on the detection signal, the flight time of the detection signal can be obtained. The flight time represents the time from when the device transmits the detection signal to when it receives the detection signal. Based on the flight time, the distance between the object to be detected and the device is calculated. Based on the distance value, the sub-region where the object to be detected is currently located is determined.

[0090] During implementation, the equipment can be equipped with a radar module and use radar ranging to quickly calculate the distance between the object to be detected and the radar module, i.e., the distance between the object to be detected and the equipment, based on the distance between the object to be detected and the equipment. Then, based on the distance between the object to be detected and the equipment, the sub-region where the object to be detected is located and the corresponding sub-sensitivity threshold can be determined. In other words, the target area where the object to be detected is located and the target sensitivity threshold can be determined, ensuring the accurate positioning of the object to be detected.

[0091] In some embodiments, when adjusting the operating mode of the device based on the detection signal and the target sensitivity threshold, it can be determined whether the detection signal matches the target sensitivity threshold; if the detection signal matches the target sensitivity threshold, the operating mode of the device is adjusted.

[0092] Specifically, determining whether the detection signal matches the target sensitivity threshold means judging whether the signal strength of the detection signal matches the target sensitivity threshold. If the signal strength of the detection signal is greater than or equal to the target sensitivity threshold, it can be determined that the detection signal matches the target sensitivity threshold, further confirming that the object to be detected in the detection area is the target object. If the signal strength of the detection signal is less than the target sensitivity threshold, it can be determined that the detection signal does not match the target sensitivity threshold, and the object to be detected in the detection area is not the target object. This improves the accuracy of the identification of the object to be detected, avoids misjudgments, and enhances the user experience.

[0093] If the detection signal matches the target sensitivity threshold, then the object to be detected in the detection area is the target object. In this case, the current working mode of the device is not suitable for the current scenario. At this time, the working mode of the device can be adjusted based on the target object to adapt to the current scenario and avoid the original working mode from causing damage to the target object.

[0094] In some embodiments, the device may also include an auxiliary functional module, which can be activated or deactivated, or its operating parameters can be adjusted, when the device's operating mode is adjusted.

[0095] The auxiliary functional modules can include disinfection, lighting, drying, air drying, and lifting functions. Correspondingly, adjusting the operating parameters of these auxiliary functional modules can involve adjusting parameters such as the irradiation angle of the disinfection lamp, lamp brightness, drying temperature, and air drying speed.

[0096] For example, if the auxiliary functional module is a UV lamp disinfection module, the device's working mode can be adjusted when someone appears in the detection area. This could be to turn off the UV lamp or adjust the UV lamp's irradiation angle to avoid harming the human body from UV irradiation.

[0097] It should be understood that, although Figure 2 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 2At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0098] One embodiment of this application also provides an application scenario in which the above-described target detection method is applied. This application scenario takes the execution of a smart clothes drying rack equipped with an ultraviolet lamp and a radar module as an example. Figure 3 As shown, in this scenario, the room height is 279.86cm, and the smart clothes drying rack is installed on the roof, mainly featuring drying, disinfection, and motor lifting functions. The radar module is positioned in the center of the smart clothes drying rack, with a maximum radiation range of 200.00cm. The human height is 173.00cm. The drying area can be divided into three sub-areas: sub-area A is the main drying area, sub-area B is an area accessible to adults, and sub-area C is an area accessible to children or pets. The distance between the sub-area and the radar module is negatively correlated with the sub-sensitivity threshold corresponding to the sub-area; that is, the sub-sensitivity threshold for sub-area A > the sub-sensitivity threshold for sub-area B > the sub-sensitivity threshold for sub-area C. The application of this method in this scenario is as follows:

[0099] Taking human detection as an example, the smart clothes dryer uses a radar module to emit a detection signal. After receiving the echo signal, it determines the flight time of the echo signal and calculates the distance between the object to be detected and the radar module based on the flight time. Based on this distance, it determines the sub-region where the object is currently located. If the object is in the second sub-region B, it checks whether the signal strength of the echo signal is greater than or equal to the sub-sensitivity threshold corresponding to the first main detection region. If the signal strength of the echo signal is greater than or equal to the sub-sensitivity threshold corresponding to the first main detection region, it can be determined that a human body exists within the first main detection region, and the smart clothes dryer turns off the ultraviolet light.

[0100] Exemplary device

[0101] Accordingly, embodiments of this application also provide a target detection device, such as... Figure 4As shown, the device may include: a first determining module 401, used to determine the target area where the object to be detected is located based on the detection signal if a detection signal is received, wherein the detection signal represents the signal returned after the object to be detected is detected within the detection area of ​​the device; a second determining module 402, used to determine the target sensitivity threshold corresponding to the target area based on the target area; and an adjusting module 403, used to adjust the working mode of the device based on the detection signal and the target sensitivity threshold.

[0102] Optionally, the detection area includes at least two sub-regions corresponding to different sub-sensitivity thresholds. Correspondingly, when determining the target region where the object to be detected is located based on the detection signal, the first determining module 401 can be specifically used to: determine the sub-region where the object to be detected is currently located based on the detection signal, and determine the sub-region as the target region.
