[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a device switching method and apparatus, and a server for home appliances, to improve the user's playback experience in perceived scenarios.

[0009] In some embodiments, the method is applied to a server, and includes: sending sensing instructions to multiple home appliances; receiving sensing results sent by the multiple home appliances; wherein the sensing results are obtained by the home appliances in response to the sensing instructions, and the sensing results include distance information between the current device and the user and communication parameters of the current device; and determining whether to switch the home appliance playing multimedia based on the sensing results.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0025] Unless otherwise stated, the term "multiple" means two or more.

[0026] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0027] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0028] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0029] Figure 1 This is a schematic diagram illustrating an implementation environment for a device switching system for home appliances provided in this embodiment of the disclosure. Figure 1 As shown, the implementation environment may include home appliances 100 and server 200.

[0030] Home appliance 100 includes a Wi-Fi (Wireless Fidelity) module and an NFC (Near Field Communication) module. The Wi-Fi module is a transmission conversion product, enabling connection to the internet; the NFC module is a near field communication product. The Wi-Fi and NFC modules are integrated into the same module, and the module program can obtain information such as the connection status between the Wi-Fi module and the router. Home appliance 100 can be a smart home device such as a television, refrigerator, or washing machine that integrates both Wi-Fi and NFC modules.

[0031] Home appliance 100 can establish a communication connection with server 200 through a router. The router is a device that connects various local area networks (LANs) and wide area networks (WANs) within the Internet. It automatically selects and sets routes based on channel conditions, sending signals in the optimal path and sequence.

[0032] The server 200 can be a single server, a server cluster consisting of several servers, or a cloud computing service center. This embodiment of the disclosure does not limit this.

[0033] It should be understood that Figure 1 The number of home appliances and servers shown is merely illustrative; depending on actual needs, there can be more than two home appliances and servers.

[0034] It should be noted that the device switching method for home appliances provided in this disclosure is generally executed jointly by the home appliance and the server. Accordingly, the device switching device for home appliances is generally set in the home appliance and the server.

[0035] In this embodiment of the disclosure, home appliances include current home appliances and other home appliances. The current home appliance refers to the home appliance that plays multimedia. Other home appliances refer to home appliances other than the current home appliance. The target home appliance refers to a home appliance that is not currently turned on but can be controlled to switch to playing multimedia.

[0036] Based on the above implementation environment, combined with Figure 2 As shown in the embodiments of this disclosure, a device switching method for home appliances is also provided, including:

[0037] S01, the server sends sensing commands to multiple home appliances.

[0038] S02, the server receives sensing results from multiple home appliances. These sensing results are obtained by the home appliances responding to sensing commands and include distance information between the current device and the user, as well as the communication parameters of the current device.

[0039] S03, the server determines whether to switch the home appliance playing multimedia based on the perception results.

[0040] The device switching method for home appliances provided in this disclosure involves a server sending sensing commands to multiple home appliances, receiving sensing results from these appliances, and then determining whether to switch the home appliance playing multimedia based on the sensing results. This allows the server receiving the sensing results to determine whether to switch the home appliance playing multimedia based on distance information and the current device's communication parameters, achieving seamless switching of multimedia playback. Even if the user moves quickly within the sensing scenario, they can still receive the multimedia played by the switched home appliance, improving the user's playback experience in the sensing scenario.

[0041] Optionally, the server determines whether to switch the home appliance playing multimedia based on the perception result, including: the server receiving... The sensing results sent by each home appliance; In this case, the server determines whether to switch the home appliance playing multimedia based on the perception results. This represents the total number of household appliances, 0.5 ≤ <1, This indicates the floor function. This prevents response delays caused by the server waiting for sensing results from all home appliances.

[0042] Optionally, communication parameters include signal strength and / or communication coverage. The server determines whether to switch the home appliance playing multimedia based on the perception results, including:

[0043] The server receives the user's movement speed, current location, and direction of movement.

[0044] When the user is moving at a low speed (represented by the movement speed), the server determines the target area based on distance information, current location, and direction of movement, and selects the nearest home appliance within that area as the target home appliance. Specifically, the nearest home appliance within the target area is the one with the smallest distance information within that area.

[0045] When the user moves at a medium speed, the server determines the target home appliance based on the signal strength and computational load of each appliance.

[0046] When the user is moving at high speed, the server selects home appliances whose signal strength meets the strength threshold and whose communication coverage meets the stable communication conditions as the target home appliances.

[0047] The server determines which home appliance is playing multimedia. This switching involves sending a first device command to the current appliance to stop multimedia playback and a second device command to the target appliance to start multimedia playback.

[0048] In this embodiment, after receiving the user's movement speed, current location, and direction of movement, if the movement speed indicates low-speed movement, the server determines the target area based on the distance information, current location, and direction of movement, and selects the nearest home appliance within the target area as the target home appliance. If the movement speed indicates medium-speed movement, the system needs to make a quick decision. The server determines the target home appliance based on the signal strength and computational load of each home appliance. If the movement speed indicates high-speed movement, the system needs to respond quickly. In this case, home appliances with signal strength meeting the strength threshold and communication coverage meeting stable communication conditions are selected as the target home appliances to ensure the continuity of multimedia audio. Thus, the server makes differentiated decisions based on the communication parameters carried by the received perception results when the user moves, achieving seamless switching of multimedia playback and ensuring a good playback experience for the user throughout their movement.

[0049] Optionally, low-speed user movement is determined as follows: the movement speed is less than or equal to a lower speed threshold. Medium-speed user movement is determined as follows: the movement speed is greater than a lower speed threshold and less than or equal to an upper speed threshold. High-speed user movement is determined as follows: the movement speed is greater than an upper speed threshold. The lower speed threshold is greater than 0 and less than or equal to 1.5 m / s (meters per second), preferably 1 m / s. The upper speed threshold is greater than 1.5 m / s and less than or equal to 4 m / s (meters per second), preferably 3 m / s. Understandably, the lower and upper speed thresholds can also be flexibly set according to the user's perception scenario, and are not limited here.

[0050] In some optional embodiments, the movement direction refers to the direction in which the user moves relative to their current location. The server determines the target area based on distance information, the current location, and the movement direction, including: the server predicting the area after the user moves based on distance information, the current location, and the movement direction; and the server determining the area after the user moves as the target area. The prediction method can employ any algorithm from Dijkstra's algorithm, ray casting algorithm, or dead reckoning algorithm, and is not specifically limited here.

[0051] Optionally, combined Figure 3 As shown, the server determines the target home appliances based on the signal strength and computational load of each appliance, including:

[0052] S11, the server determines the computational load index of each home appliance based on its computational load.

[0053] S12, the server selects home appliances whose signal strength meets the strength threshold condition and whose calculated load index meets the load threshold condition as target home appliances.

[0054] In this way, the server determines the computational load index of each home appliance based on its computational load, and selects home appliances whose signal strength meets the strength threshold condition and whose computational load index meets the load threshold condition as target home appliances, so that the system can make decisions quickly and achieve seamless switching of multimedia playback.

[0055] In some alternative embodiments, computational load metrics include CPU (Central Processing Unit) utilization or network latency. As a specific example, computational load metrics may meet load threshold conditions, including: CPU utilization being less than or equal to a utilization threshold, or network latency being less than or equal to a set network latency.

[0056] Optionally, the signal strength meets the strength threshold condition, including: the signal strength is greater than or equal to the signal strength threshold. Here, the signal strength threshold represents the average signal strength received by the server from home appliances, or the second largest signal strength received by the server from home appliances.

[0057] The communication coverage area meets the conditions for stable communication, including that the target area is within the communication coverage area. Thus, when the server determines that a user is moving at high speed, it can select home appliances with relatively good signal strength and whose location after the user's movement is within the communication coverage area as target home appliances, to accommodate the user's high-speed movement.

[0058] Optionally, the device switching method for home appliances further includes:

[0059] The server receives the user's movement direction.

[0060] The server determines the target direction for multimedia playback on the current home appliance based on the movement direction and adjusts the appliance to play multimedia in that direction. The target direction for multimedia playback on the current home appliance refers to the direction in which the multimedia is played after the appliance is rotated.

[0061] In some optional embodiments, the server adjusts the current home appliance to play multimedia in a target direction, including: if the current home appliance has a rotation function, the server controls the current home appliance to rotate so that the multimedia playback direction and the movement direction are the same after the rotation. It is understood that if the current home appliance does not have a rotation function, the current home appliance does not perform a rotation operation.

[0062] Thus, in this embodiment of the disclosure, by controlling the rotation of a current home appliance with a rotation function, the direction of movement can be aligned with the user's, ensuring the continuity of multimedia audio.

[0063] Optionally, the device switching method for home appliances further includes:

[0064] The server gradually reduces the multimedia playback volume of the current home appliances as the distance information decreases;

[0065] And / or, the server gradually increases the multimedia playback volume of the target home appliance as the distance information increases.

[0066] In some alternative embodiments, the lower the movement speed, the slower the server adjusts the multimedia playback volume of the current home appliance, while the higher the movement speed, the faster the server adjusts the multimedia playback volume of the current home appliance.

[0067] In some alternative embodiments, the lower the movement speed, the slower the server adjusts the multimedia playback volume of the target home appliance, while the higher the movement speed, the faster the server adjusts the multimedia playback volume of the target home appliance.

[0068] In some optional embodiments, the first device instruction is generated and sent to the current home appliance when the server determines the target home appliance, and / or, the second device instruction is generated and sent to the target home appliance when the server determines the target home appliance. In a specific example, after the server determines the current home appliance and the target home appliance, it sends the first device instruction to the current home appliance and the second device instruction to the target home appliance simultaneously, so as to achieve seamless switching of multimedia playback.

[0069] In another specific example, after the server identifies the target home appliance, it first sends a second device command to the target appliance, and then sends the first device command to the current appliance after a preset interval. This seamlessly switches multimedia playback while preventing the user from being unable to receive the multimedia due to excessive distance from the current appliance. The preset duration is greater than zero and less than or equal to a maximum duration threshold. The maximum duration threshold can be a real number less than 2 seconds.

[0070] Understandably, the preset duration can also be determined based on the sparseness of the distribution of home appliances in the user's scenario. For example, the more dispersed the distribution of home appliances in the user's scenario, the longer the preset duration; conversely, the more densely distributed the home appliances in the user's scenario, the shorter the preset duration.

[0071] Combination Figure 4 As shown in the embodiments of this disclosure, a device switching method for home appliances is also provided, including:

[0072] S21, the home appliance responds to the sensing command, performs sensing, and obtains the sensing results. These results include the distance information between the current device and the user, and the communication parameters of the current device.

[0073] S22, the home appliance sends the sensing results to the server. These sensing results are used to determine the switching of the home appliance playing multimedia.

[0074] S23, the home appliance will switch when the server determines which home appliance will play multimedia.

[0075] The device switching method for home appliances provided in this disclosure involves the home appliance responding to a sensing command to obtain a sensing result including distance information and the current device's communication parameters. The sensing result is then sent to a server to determine which home appliance should play multimedia. When the server determines to switch the multimedia playback device, the home appliance performs the switch. Thus, the server receiving the sensing result can determine whether to switch the multimedia playback device based on the distance information and the current device's communication parameters, achieving seamless multimedia playback switching. Even if the user moves quickly within the sensing scenario, they can still receive the multimedia played by the switched home appliance, improving the user's playback experience in the sensing scenario.

[0076] In some optional embodiments, the home appliances send sensing results to the server, including: the current home appliance sending sensing results to the server, and other home appliances sending sensing results to the server. After receiving the sensing results sent by the current home appliance and other home appliances, the server determines whether to switch the home appliance playing multimedia based on the aforementioned sensing results.

[0077] While the home appliance sends a sensing result used to determine the switching of the home appliance playing multimedia, if the user moves away from the current home appliance playing multimedia within the sensing scenario, the multimedia volume received by the user gradually decreases as the user moves, and may even result in the user not receiving multimedia at all. Based on this, in this embodiment of the disclosure, the sensing result is also used to adjust the volume of the home appliance, so as to achieve seamless switching of multimedia playback while adaptively controlling the volume of the home appliance, further optimizing the user's playback experience within the sensing scenario.

[0078] Optionally, the sensing results are also used for volume adjustment of home appliances. In some optional embodiments, volume adjustment of home appliances includes: increasing the volume of the home appliance or decreasing the volume of the home appliance.

[0079] In this way, the server receiving the perception results can also adaptively adjust the volume of the current home appliance playing multimedia, so that users in the perception scenario will not notice the change in multimedia volume when moving away from the aforementioned home appliance, further optimizing the user's playback experience in the perception scenario.

[0080] Optionally, when the server determines which home appliance is playing multimedia, the switching is performed, including: the current home appliance responding to the first device instruction and stopping multimedia playback.

[0081] In this way, after the home appliance sends the sensing results to the server, the current home appliance that receives the first device instruction responds to the first device instruction and stops multimedia playback, thus achieving seamless switching of multimedia playback.

[0082] Optionally, the home appliance performs the switching when the server determines which home appliance will play multimedia, including: the target home appliance responding to the second device instruction and starting multimedia playback. It should be noted that the target home appliance is determined by the server based on the perception results.

[0083] In this way, after the home appliance sends the sensing results to the server, the target home appliance that receives the instruction from the second device responds to the instruction and stops multimedia playback, achieving a seamless switch in multimedia playback. Even if the user moves quickly within the sensing scenario, the user can still receive the multimedia played by the switched home appliance, which helps improve the user's playback experience in the sensing scenario.

[0084] Optionally, the device switching method for home appliances further includes: the home appliance responding to a sensing command to perform sensing; and before obtaining the sensing result, responding to a user command to start multimedia playback. Thus, in this embodiment of the disclosure, before the home appliance responding to a sensing command to perform sensing, the user sends a user command to the home appliance to start multimedia playback, enabling autonomous selection of the multimedia playback device.

[0085] It should be noted that, in response to a user command and after starting multimedia playback, the process also includes: sending a notification message to the server to notify that this device is the current home appliance.

[0086] In practical applications, such as Figure 5 As shown, the specific steps for switching devices for home appliances are as follows:

[0087] S31, the server sends sensing commands to multiple home appliances.

[0088] S32, the home appliance responds to the sensing command, performs sensing, and obtains the sensing results. These results include distance information between the current device and the user, and the signal strength and / or communication coverage range of the current device. The home appliance includes the current device and other home appliances.

[0089] S33, the server receives the sensing results sent by multiple home appliances.

[0090] S34, the server receives the user's movement speed, current location, and direction of movement.

[0091] S35, when the moving speed is less than or equal to 1m / s, the server determines the target area based on the distance information, current location, and moving direction, and selects the home appliance closest to the user in the target area as the target home appliance.

[0092] S36, when the moving speed is greater than 1m / s and less than or equal to 3m / s, the server determines the target home appliance based on the signal strength and computing load of each home appliance.

[0093] S37, when the moving speed is greater than 3m / s, the server selects home appliances whose signal strength meets the strength threshold condition and whose communication coverage meets the stable communication condition as the target home appliances.

[0094] S38, the server sends a first device command to the current home appliance to stop multimedia playback, and sends a second device command to the target home appliance to start multimedia playback.
