Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and in particular to a wake-up method, wake-up device, wake-up system, electronic device, medium, and product. Background Technology

[0002] With the development of electronic devices, more and more electronic devices support wake-up functionality. When multiple electronic devices that support wake-up and have the same wake-up command are located in the same area, a problem can easily arise where a single command can wake up all the devices simultaneously. For example, if multiple electronic devices such as mobile phones, computers, and vehicles have the same wake-up command, when the wake-up command is output, the multiple electronic devices that receive the command will be woken up at the same time.

[0003] Currently, the problem of one call triggering multiple responses is solved through collaborative wake-up functionality. For example, in a home setting, multiple devices such as speakers, TVs, and projectors that can be woken up by a wake-up command can form a collaborative wake-up network, and then the decision on which device to wake up is made within the group. Summary of the Invention

[0004] To overcome the problems existing in related technologies, this disclosure provides a wake-up method, a wake-up device, a wake-up system, an electronic device, a medium, and a product.

[0005] According to a first aspect of the present disclosure, a wake-up method is provided, executed by a first device, the method comprising: Acquire second wake-up related information of the second device, wherein the second device is a device that receives a wake-up command, and the second wake-up related information includes a second object detection result used to characterize whether a target object exists in the space where the second device is located; At least based on the first wake-up related information of the first device and the second object detection result, it is determined whether the device is woken up by the received wake-up command. The first wake-up related information includes a first object detection result used to characterize whether the target object exists in the space where the first device is located.

[0006] In this way, wake-up decisions are made only for devices within the space where the target object exists, effectively reducing the workload of comparing distances between multiple devices and the object from which the wake-up command originates, and significantly improving wake-up efficiency. Furthermore, since the detection result of the presence of the target object in the space is considered when deciding whether to wake up, the probability of false wake-ups due to reverberation can be reduced to some extent, thereby improving wake-up accuracy.

[0007] In some possible implementations, determining whether to wake up by a received wake-up command, based at least on the first wake-up-related information of the first device and the object detection result, includes: If the first object detection result indicates that the target object exists in the space where the first device is located, the second object detection result indicates that the target object does not exist in the space where the second device is located, and there is no second device located in the same space as the first device, then the device is awakened by the received wake-up command.

[0008] This solves the problem of inaccurate wake-up in some scenarios due to the inability to accurately determine the distance between the device and the source object of the wake-up command. Furthermore, without the user's awareness, the device the user intends to wake can be directly woken up by the wake-up command among multiple devices, eliminating the need for complex distance comparisons between devices, reducing latency in the wake-up process, and improving wake-up efficiency. Secondly, since there is no target object in the space where the devices are located, these devices will not be falsely woken up, avoiding unnecessary device responses, reducing waste of system resources, and minimizing interference that may be caused by false wake-ups. This enhances the user experience.

[0009] In some possible implementations, the first wake-up related information may further include a first distance between the first device and the source object of the wake-up command, and the second wake-up related information may further include a second distance between the second device and the source object; The step of determining whether to wake up by the received wake-up command based at least on the first wake-up related information of the first device and the object detection result includes: Based on the first object detection result, the first distance, the second object detection result, and the second distance, determine whether the object is awakened by the received wake-up command.

[0010] In this way, the first device makes a comprehensive decision on whether to be woken up by the received wake-up command based on the object detection results of each device and the distance between each device and the source object of the wake-up command, thereby further improving the accuracy of wake-up.

[0011] In some possible implementations, determining whether to be woken up by a received wake-up command based on the first object detection result, the first distance, the second object detection result, and the second distance includes: If the target object exists in the space where the first device is located, and the target object also exists in the space where at least one second device is located, then it is determined whether to wake up by the received wake-up command based on the first distance and the second distance between the second device in the space containing the target object and the source object.

[0012] By adopting the above technical solution, wake-up decisions are made only on devices located in the space where the target object exists. This effectively reduces the workload of comparing the distances of multiple devices to the source object of the wake-up command, significantly improving wake-up efficiency. Furthermore, without the user noticing, the decision on whether to wake up is made by combining the proximity principle and object detection results, improving the accuracy of proximity-based wake-up and solving the problem of inaccurate proximity-based wake-up caused by device hardware and placement.

[0013] In some possible implementations, the method further includes: If there is no device in the second device that is in the same space as the first device, then the existence of the target object in the space where the first device is located is determined based on the first object detection result; or If there is at least one second device in the second device that is located in the same space as the first device, then the existence of the target object in the space where the first device and the at least one second device are located is determined based on the first object detection result and the second object detection result of the at least one second device.

[0014] This improves the reliability and accuracy of determining whether the target object exists in the space where the first device is located.

[0015] In some possible implementations, determining whether to wake up by a received wake-up command based on the first distance, the second distance between the second device containing the target object in space and the source object, includes: If the first distance is less than the second distance, the device will be woken up by the received wake-up command.

[0016] Thus, based on the principle of proximity, the distance between multiple devices containing the target object in space and the source object of the wake-up command is compared, and the device closest to the source object is woken up, thereby improving the accuracy of wake-up control.

[0017] In some possible implementations, obtaining the second wake-up related information of the second device includes: The system receives a second broadcast message sent by a second device to obtain second wake-up related information of the second device. The second broadcast message is sent by the second device when it receives a wake-up command, and the second broadcast message includes the second wake-up related information.

[0018] Thus, by receiving the second broadcast message sent by the second device to obtain the second wake-up related information, the convenience of obtaining the second wake-up related information is improved, unnecessary communication between devices is reduced, and communication overhead and the complexity of interaction between devices are effectively reduced.

[0019] In some possible implementations, the method further includes: In response to receiving the wake-up command, a first broadcast message is sent, the first broadcast message including the wake-up-related information.

[0020] This reduces unnecessary communication between devices, effectively reducing communication overhead and the complexity of device interactions. Furthermore, because other devices consider the first device's wake-up information when deciding whether to wake themselves up, the accuracy of wake-up is improved.

[0021] In some possible implementations, the method further includes: The presence of the target object in the space where the first device is located is detected by ultrasonic signals to obtain the detection result of the first object.

[0022] By employing the above technical solution, the presence of a target object in the space where the ultrasonic signal detection device is located can be used. This allows for the reuse of existing hardware within the device, avoiding the need for additional hardware deployment, thus reducing hardware costs and simplifying device design. Furthermore, reusing existing hardware reduces the resource consumption during the wake-up process, improving wake-up efficiency.

[0023] In some possible implementations, the method further includes: Determining the location of the first device using ultrasonic signals; and / or The presence of a device in the same space as the first device is detected by ultrasonic signals.

[0024] By using the above technical solution, ultrasonic signals can be used to determine the space where the first device is located and / or whether there is a device in the same space as the first device. Therefore, when deciding whether to wake up, the existence of a device in the same space as the first device is also considered, which further improves the accuracy of the wake-up control.

[0025] According to a second aspect of the present disclosure, a wake-up method is provided, executed by a second device, the method comprising: In response to receiving a wake-up command, a second wake-up related information is sent, the second wake-up related information including a second object detection result characterizing whether a target object exists in the space where the second device is located, so that the first device can execute the wake-up method according to the first aspect of the embodiments of this disclosure.

[0026] In this way, the first device only makes wake-up decisions for devices in the space where the target object exists, effectively reducing the workload of comparing the distance between multiple devices and the object from which the wake-up command originates, and significantly improving wake-up efficiency. Furthermore, since the detection result of the presence of the target object in the space is taken into account when deciding whether to wake up, the probability of false wake-ups caused by reverberation can be reduced to some extent, thereby improving the accuracy of wake-up.

[0027] According to a third aspect of the present disclosure, a wake-up device is provided, deployed in a first device, the device comprising: The acquisition module is configured to acquire second wake-up related information of a second device, wherein the second device is a device that receives a wake-up command, and the second wake-up related information includes a second object detection result used to characterize whether a target object exists in the space where the second device is located; The first determining module is configured to determine whether to be woken up by the received wake-up command based at least on the first wake-up related information of the first device and the object detection result, wherein the first wake-up related information includes a first object detection result used to characterize whether a target object exists in the space where the first device is located.

[0028] According to a fourth aspect of the present disclosure, a wake-up device is provided, deployed in a second device, the device comprising: The second sending module is configured to send second wake-up related information in response to receiving a wake-up command. The second wake-up related information includes a second object detection result for characterizing whether a target object exists in the space where the second device is located, so that the first device can execute the wake-up method described in the first aspect of the present disclosure.

[0029] According to a fifth aspect of the present disclosure, a wake-up system is provided, the system including a first device and a second device; The first device is used to perform the wake-up method described in the first aspect of the embodiments of this disclosure; The second device is used to perform the wake-up method described in the second aspect of the embodiments of this disclosure.

[0030] According to a sixth aspect of the present disclosure, an electronic device is provided, comprising: processor; Memory used to store processor-executable instructions; The processor is configured to execute the instructions to cause the electronic device to perform the wake-up method steps of the first aspect of the present disclosure, or to perform the wake-up method steps of the second aspect of the present disclosure.

[0031] According to a seventh aspect of the present disclosure, a computer-readable storage medium is provided that stores computer program instructions thereon, which, when executed by a processor, implement the steps of the wake-up method described in the first aspect of the present disclosure, or implement the steps of the wake-up method described in the second aspect of the present disclosure.

[0032] According to an eighth aspect of the present disclosure, a computer program product is provided, including a computer program that, when executed by a processor, implements the steps of the wake-up method described in the first aspect of the present disclosure, or implements the steps of the wake-up method described in the second aspect of the present disclosure.

[0033] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0040] Figure 6 This is a block diagram illustrating an electronic device according to an exemplary embodiment. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0043] In related technologies, collaborative wake-up functionality can wake up only the device closest to the user. However, when multiple devices exist in a collaborative wake-up network, each device needs to compare its distance to the object that issued the wake-up command, increasing the workload and resulting in lower wake-up efficiency. Furthermore, due to device placement, reverberation may occur, making the distance determined based on the strength of the received wake-up command inaccurate, thus affecting wake-up accuracy.

[0044] In view of this, the present disclosure provides a wake-up method, a wake-up device, a wake-up system, an electronic device, a computer-readable medium, and related products. In this method, when deciding whether to wake up, the first device comprehensively considers both the detection result of a second object (the presence of a target object in the space where the second device is located) and the detection result of a first object (the presence of a target object in the space where the first device is located). In this way, wake-up decisions are made only for devices in the space where the target object exists, effectively reducing the workload of comparing distances between multiple devices and the source object of the wake-up command, and significantly improving wake-up efficiency. Furthermore, since the detection result of the presence of a target object in the space is considered when deciding whether to wake up, the probability of false wake-ups due to reverberation can be reduced to a certain extent, thereby improving the accuracy of wake-up.

[0045] Figure 1 This is a schematic diagram illustrating a usage scenario according to an exemplary embodiment. For example... Figure 1 As shown, suppose a home includes multiple devices, such as device 1 in the entryway, device 2 in the living room, device 3 in the secondary bedroom, device 4 in the master bedroom, device 5 in the study, and device 6 in the children's room. All these devices share the same wake-up command; that is, all devices can be woken up by the same wake-up command.

[0046] For example, the aforementioned devices may include speakers, televisions, mobile phones, computers, projectors, smart clothes racks, air conditioners, robot vacuum cleaners, etc. The first device involved in this disclosure may be... Figure 1 Any one of the multiple devices shown, the second device is Figure 1 All devices shown, excluding the first device. For example, the first device is device 2 located in the living room, and the second devices may include device 1, device 3, device 4, device 5, and device 6.

[0047] It should be understood that, Figure 1Only the wake-up scenarios of multiple devices in a home are shown. The wake-up method provided by the present disclosure can also be applied in a trolley scenario. For example, the first device can be a vehicle, and the second device can be any device in the vehicle that can be woken up by the same wake-up instruction.

[0048] The present disclosure does not specifically limit the applicable scenarios of the provided wake-up method.

[0049] Figure 2 is a flowchart of a wake-up method shown according to an exemplary embodiment. The wake-up method can be executed by a first device. As Figure 2 shown, the wake-up includes the following steps.

[0050] In step S21, obtain the second wake-up related information of the second device. The second device is the device that receives the wake-up instruction. The second wake-up related information includes a second object detection result for characterizing whether there is a target object in the space where the second device is located.

[0051] In step S22, determine whether to be woken up by the received wake-up instruction at least based on the first wake-up related information of the first device and the second object detection result. The first wake-up related information includes a first object detection result for characterizing whether there is a target object in the space where the first device is located.

[0052] Exemplarily, the second device can be one or more devices other than the first device that receive the wake-up instruction within the same cooperative wake-up network as the first device. For example, the first device is device 2 located in the living room, and the second devices can include device 1, device 3, device 4, device 5, and device 6.

[0053] Among them, the wake-up instructions for the first device and the second device are the same. The wake-up instruction can be, for example, a preset wake-up word, and the wake-up word can be a word or a phrase composed of one or more characters. For example, the wake-up word can be "Xiaoi Tongxue".

[0054] In the present disclosure, before the second device receives the wake-up instruction and before waking up, it will send the second wake-up related information, which at least includes a second object detection result for characterizing whether there is a target object in the space where the second device is located. Given that it is usually people who wake up the device, and people usually prefer to use the device closest to themselves, the target object can be defined as a person. Accordingly, the second object detection result is the detection result of whether there is a person in the space where the second device is located.

[0055] For example, the second device has the function of detecting whether a target object exists in the space where the second device is located. For example, the second device is equipped with human detection devices such as infrared sensors and cameras to detect whether a person exists in the space where the second device is located. It should be understood that in this disclosure, the target object can be a general term for people and is not specifically limited to a particular person; that is, it is not necessary to identify whether the person in the space is an adult, a child, or a specific person.

[0056] Similarly, the first device also needs to detect whether there is a target object in its own space. That is, the first device also needs to generate first wake-up related information, and the first wake-up related information includes at least a first object detection result used to characterize whether there is a target object in the space where the first device is located.

[0057] Devices typically include a voice player and a voice receiver, such as a speaker and a microphone. To avoid increasing hardware costs by deploying additional hardware in the device, in this disclosure, the device can detect the presence of a target object in its space by reusing its own voice player and voice receiver.

[0058] In one embodiment, the method further includes: The presence of a target object in the space where the first device is located is detected by ultrasonic signals, so as to obtain the detection result of the first object.

[0059] In this embodiment, an ultrasonic signal can be played by a voice player deployed in the first device, and the reflected ultrasonic signal can be received. Based on the played ultrasonic signal and the reflected ultrasonic signal, it can be determined whether there is a person in the space where the first device is located, so as to obtain the first object detection result.

[0060] The second device also plays ultrasonic signals through a voice player deployed in the second device and receives reflected ultrasonic signals. Based on the played ultrasonic signals and the reflected ultrasonic signals, it identifies whether there is a person in the space where the second device is located, so as to obtain the second object detection result.

[0061] For example, the devices (such as the first device and / or the second device) can periodically detect whether there is a person in the space they are in, obtain the object detection result, and send wake-up related information to other devices when they receive a wake-up command.

[0062] For example, in order to reduce the workload of object detection, the device can start detecting whether there is a person in the space it is in when it receives a complete wake-up command to obtain the object detection result, and send wake-up related information to other devices.

[0063] Considering that detecting an object only after receiving a complete wake-up command might lead to delayed wake-up and poor wake-up timeliness, the device can, for example, begin detecting the presence of a person in its surroundings upon receiving a partial wake-up command to obtain object detection results, and only send wake-up related information to other devices upon receiving the complete wake-up command. For instance, if the wake-up command includes a wake word, the device can begin detecting the presence of a person in its surroundings upon receiving a partial wake word (such as "Xiao Ai Tong"), and only send wake-up related information to other devices upon receiving "Xiao Ai Tongxue".

[0064] By employing the above technical solution, the presence of a target object in the space where the ultrasonic signal detection device is located can be used. This allows for the reuse of existing hardware within the device, avoiding the need for additional hardware deployment, thus reducing hardware costs and simplifying device design. Furthermore, reusing existing hardware reduces the resource consumption during the wake-up process, improving wake-up efficiency.

[0065] Furthermore, in this disclosure, the first device can obtain the second wake-up related information of the second device in any way, such as through wired or wireless communication. However, since multiple devices are typically deployed in different rooms within a home, to avoid problems caused by connecting multiple devices via wiring harnesses, in this disclosure, the first device can obtain the second wake-up related information of the second device wirelessly.

[0066] Considering that in a collaborative wake-up network, multiple devices located within the same network can send information to other devices via broadcast and receive broadcast messages from other devices, in one embodiment, obtaining the second wake-up-related information of the second device may include: The system receives a second broadcast message sent by a second device to obtain second wake-up related information of the second device. The second broadcast message is sent by the second device when it receives a wake-up command, and the second broadcast message includes the second wake-up related information.

[0067] In this embodiment, the second device sends a second broadcast message upon receiving a wake-up command. The second broadcast message includes second wake-up-related information. The first device can listen to the broadcast message and, upon receiving the second broadcast message, can obtain the second wake-up-related information from it.

[0068] Thus, by receiving the second broadcast message sent by the second device to obtain the second wake-up related information, the convenience of obtaining the second wake-up related information is improved, unnecessary communication between devices is reduced, and communication overhead and the complexity of interaction between devices are effectively reduced.

[0069] To facilitate other devices, such as a second device, in deciding whether to be woken up based on the first wake-up related information of the first device and the second wake-up related information of the second device, in this disclosure, the second device can also obtain the first wake-up related information of the first device.

[0070] In this disclosure, the method may further include: In response to receiving the wake-up command, a first broadcast message is sent, the first broadcast message including the wake-up-related information.

[0071] When the first device receives a wake-up command, it sends a first broadcast message to the surrounding devices so that other devices can obtain first wake-up related information from the first broadcast message they are listening to, and then decide whether to be woken up based on the obtained first wake-up related information and the wake-up related information of other devices.

[0072] This reduces unnecessary communication between devices, effectively reducing communication overhead and the complexity of device interactions. Furthermore, because other devices consider the first device's wake-up information when deciding whether to wake themselves up, the accuracy of wake-up is improved.

[0073] By adopting the above technical solution, when deciding whether to wake up, the first device comprehensively considers both the second object detection result (whether the target object exists in the space where the second device is located) and the first object detection result (whether the target object exists in the space where the first device is located). In this way, wake-up decisions are only made for devices in the space where the target object exists, effectively reducing the workload of comparing distances between multiple devices and the object from which the wake-up command originates, thus significantly improving wake-up efficiency. Furthermore, because the detection result of the target object's presence in the space is considered when deciding whether to wake up, the probability of false wake-ups due to reverberation can be reduced to some extent, thereby improving wake-up accuracy.

[0074] In this disclosure, for each device, after the device's collaborative wake-up function is enabled, the space is first divided, that is, the space in which the device itself is located is determined.

[0075] In one embodiment, the method may further include: Determining the location of the first device using ultrasonic signals; and / or The presence of a device in the same space as the first device is detected by ultrasonic signals.

[0076] For example, each device can identify its own spatial location using an ultrasonic spatial perception algorithm. For instance, the first device determines the boundaries of its spatial location by sending and receiving ultrasonic signals. Figure 1As shown, device 1 determines the boundary of its own space by sending and receiving ultrasonic signals, thereby determining its own location. For example, the space where device 1 is located is... Figure 1 The living room in the middle.

[0077] For example, each device can use ultrasonic spatial sensing algorithms to identify whether other devices exist in its surrounding space. Figure 1 As shown, the living room includes device 1 and device 2. Device 1 uses an ultrasonic spatial perception algorithm to identify that device 2 also exists in its space. Similarly, device 2 uses an ultrasonic spatial perception algorithm to identify that device 1 also exists in its space.

[0078] By using the above technical solution, ultrasonic signals can be used to determine the space where the first device is located and / or whether there is a device in the same space as the first device. Therefore, when deciding whether to wake up, the existence of a device in the same space as the first device is also considered, which further improves the accuracy of the wake-up control.

[0079] The following is about Figure 2 The specific implementation method of step S22 will be described.

[0080] In one embodiment, determining whether to wake up by a received wake-up command based at least on the first wake-up-related information of the first device and the object detection result may include: If the first object detection result indicates that the target object exists in the space where the first device is located, the second object detection result indicates that the target object does not exist in the space where the second device is located, and there is no second device located in the same space as the first device, then the device is awakened by the received wake-up command.

[0081] In this embodiment, if the space where the first device is located contains a target object, the space where the second device is located does not contain a target object, and there is no second device in the same space as the first device, then it indicates that the space where the first device is located only includes the first device, and the user is located in the space where the first device is located. In this case, the probability that the user intends to wake up the first device is high. Therefore, the first device can be woken up by the received wake-up command.

[0082] When the space containing the first device only includes the first device, and the target object exists in the space containing the first device, while the target object does not exist in the space containing the second device, the first device is directly awakened by the wake-up command. This solves the problem of inaccurate wake-up in some scenarios due to the inability to accurately determine the distance between the device and the source object of the wake-up command. Furthermore, without the user's awareness, among multiple devices, the device the user intends to wake can be directly awakened by the wake-up command without complex distance comparisons between devices, reducing latency in the wake-up process and improving wake-up efficiency. Since the space containing the second device does not contain the target object, these devices will not be falsely awakened, avoiding unnecessary device responses, reducing waste of system resources, and minimizing interference that may result from false awakenings. This enhances the user experience.

[0083] Considering that users usually wake up devices that are close to them, the first device may also include the distance between each device and the source object of the wake-up command when deciding whether to wake itself up.

[0084] In another embodiment, the first wake-up related information further includes a first distance between the first device and the source object of the wake-up command, and the second wake-up related information further includes a second distance between the second device and the source object. For example, the first device can determine the first distance between itself and the source device of the wake-up command based on the signal strength of the wake-up command it receives. Similarly, the second device can also determine the second distance between itself and the source device of the wake-up command based on the signal strength of the wake-up command it receives. The second broadcast message sent by the second device includes the second distance and a second object detection result. There can be one or more second devices. When there are multiple second devices, each second device determines its own second distance from the source device of the wake-up command and a second object detection result used to characterize whether a target object exists in the space where the second device is located, and then sends a second broadcast message including the second distance and the second object detection result.

[0085] For example, such as Figure 1 As shown, each device sends a broadcast message, which includes the distance between itself and the source device of the wake-up command, as well as the object detection result of whether the target object exists in its own space.

[0086] In this embodiment, determining whether to wake up by a received wake-up command based at least on the first wake-up related information of the first device and the object detection result includes: Based on the first object detection result, the first distance, the second object detection result, and the second distance, determine whether the object is awakened by the received wake-up command.

[0087] In this embodiment, the first device determines whether to be woken up by the received wake-up command based on the first object detection result, the first distance, the second object detection result, and the second distance.

[0088] In this way, the first device makes a comprehensive decision on whether to be woken up by the received wake-up command based on the object detection results of each device and the distance between each device and the source object of the wake-up command, thereby further improving the accuracy of wake-up.

[0089] In one implementation, determining whether to be woken up by a received wake-up command based on the first object detection result, the first distance, the second object detection result, and the second distance may include: If the target object exists in the space where the first device is located, and the target object also exists in the space where at least one second device is located, then it is determined whether to wake up by the received wake-up command based on the first distance and the second distance between the second device in the space containing the target object and the source object.

[0090] In this embodiment, the method may further include: If there is no device in the second device that is in the same space as the first device, then the existence of the target object in the space where the first device is located is determined based on the first object detection result; or If there is at least one second device in the second device that is located in the same space as the first device, then the existence of the target object in the space where the first device and the at least one second device are located is determined based on the first object detection result and the second object detection result of the at least one second device.

[0091] When the space containing the first device only includes the first device, the presence of a target object in the space containing the first device can be determined solely based on the first object detection result. When the space containing the first device includes at least one second device in addition to the first device, the presence of a target object in the space containing both the first device and the second object detection result of the second device located in the same space as the first device can be determined based on the first object detection result and the second object detection result of the second device located in the same space as the first device. For example, if the first object detection result indicates that the space containing the first device does not contain a target object, but the second object detection result of the second device located in the same space as the first device indicates that the space containing the second device contains a target object, then it is determined that the space containing both the first device and the second device contains a target object. Alternatively, if the first object detection result indicates that the space containing the first device contains a target object, but the second object detection result of the second device located in the same space as the first device indicates that the space containing the second device does not contain a target object, then it is also determined that the space containing both the first device and the second device contains a target object.

[0092] This improves the reliability and accuracy of determining whether the target object exists in the space where the first device is located.

[0093] Similarly, the above method can be used to determine whether a target object exists in the space where the second device is located. For each second device, it is determined whether there is a device in the same space as the first device and all second devices. If so, the existence of a target object in the space where the second device is located is determined based on the second object detection result of the second device and the object detection result of the device in the same space as the second device. For example, if the first device and the second device are in the same space, the first object detection result indicates that a target object exists in the space, and the second object detection result of the second device indicates that a target object does not exist in the space, then it is determined that a target object exists in the space where the second device is located (i.e., the space where the first device is located).

[0094] Thus, by following the above method, it can be determined whether the space where the first device is located and the space where each second device is located contain a target object.

[0095] If it is determined that a target object exists in the space where the first device is located, and a target object exists in the space where at least one second device is located, then it is determined whether to wake up by the received wake-up command based on the first distance and the second distance between the second device with the target object in the space and the source object.

[0096] For example, refer to Figure 1 Assuming the first device is device 2, and the second devices are devices 1, 3, 4, 5, and 6, if the object detection results from devices 2 and 1 determine that a target object exists in the living room and in the secondary bedroom where device 3 is located, but no target object exists in the spaces where the other devices are located, then the first device determines whether it should be woken up by the received wake-up command based on the second distance between device 1 and the source device, the first distance between device 2 and the source device, and the second distance between device 3 and the source device. Alternatively, if the object detection results from devices 2 and 1 determine that a target object exists in the living room and in the secondary bedroom where device 3 is located, then the first device determines whether it should be woken up by the received wake-up command based on the second distance between device 1 and the source device and the first distance between device 2 and the source device.

[0097] The step of determining whether to be woken up by a received wake-up command based on the first distance, the second distance between the second device containing the target object in space and the source object, may include: If the first distance is less than the second distance, the device will be woken up by the received wake-up command.

[0098] Thus, based on the principle of proximity, the distance between multiple devices containing the target object in space and the source object of the wake-up command is compared, and the device closest to the source object is woken up, thereby improving the accuracy of wake-up control.

[0099] By adopting the above technical solution, wake-up decisions are made only on devices located in the space where the target object exists. This effectively reduces the workload of comparing the distances of multiple devices to the source object of the wake-up command, significantly improving wake-up efficiency. Furthermore, without the user noticing, the decision on whether to wake up is made by combining the proximity principle and object detection results, improving the accuracy of proximity-based wake-up and solving the problem of inaccurate proximity-based wake-up caused by device hardware and placement.

[0100] As an example, assuming the first device is device A and the second device is device B, several scenarios may occur as shown in Table 1.

[0101] Table 1

[0102] In Table 1, LA represents the distance between device A and the source object of the wake-up command, and LB represents the distance between device B and the source object of the wake-up command. For example, when devices A and B are located in different spaces, if only one space contains a person, the device located in the space containing the person will be woken up. When devices A and B are located in different spaces, if both spaces contain people, the device that is woken up will be determined based on the distance between each device A and device B and the source object of the wake-up command; for example, the device that is closest will be woken up.

[0103] When devices A and B are in the same space, regardless of which device detects a person, the device to be woken up is determined based on the distance between each device A and device B and the source object of the wake-up command. For example, the device that is closest is woken up.

[0104] Similarly, when there are multiple devices as the second device, referring to the control strategy described above, the device closest to the source object is determined to be woken up based on the distance between each device located in the space where people are present and the source object of the wake-up command.

[0105] Based on the same inventive concept, this disclosure provides a wake-up method, which is executed by a second device. Figure 3 This is a flowchart illustrating a wake-up method according to an exemplary embodiment. For example... Figure 3 As shown, the wake-up method is executed by a second device, and the wake-up method may include step S31.

[0106] In step S31, in response to receiving a wake-up command, a second wake-up related information is sent, which includes a second object detection result used to characterize whether a target object exists in the space where the second device is located.

[0107] The second device sends second wake-up related information so that the first device can determine whether to be woken up by the received wake-up command based on the first wake-up related information and the second object detection result of the first device.

[0108] In this way, the first device only makes wake-up decisions for devices in the space where the target object exists, effectively reducing the workload of comparing the distance between multiple devices and the object from which the wake-up command originates, and significantly improving wake-up efficiency. Furthermore, since the detection result of the presence of the target object in the space is taken into account when deciding whether to wake up, the probability of false wake-ups caused by reverberation can be reduced to some extent, thereby improving the accuracy of wake-up.

[0109] Based on the same inventive concept, this disclosure also provides a wake-up device.
