[0021] Figure 1FIG. 1 is a schematic diagram of an implementation environment of a device switching system for home appliances provided by an embodiment of the present disclosure. Figure 1 As shown, the implementation environment may include a home appliance 100 and a server 200 .

[0022] 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 that can be used to establish a connection with 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 a Wi-Fi module and an NFC module.

[0023] The home appliance 100 can establish a communication connection with the server 200 through a router. The router is a device that connects the local area networks and wide area networks in the Internet. It automatically selects and sets routes based on the channel conditions and sends signals in the best path and in a sequential order.

[0024] The server 200 may be a single server, a server cluster consisting of several servers, or a cloud computing service center, which is not limited in the embodiments of the present disclosure.

[0025] It should be understood that Figure 1 The number of home appliances and service terminals is only for reference. There may be more than two home appliances and service terminals according to actual needs.

[0026] It should be noted that the device switching method for home appliances provided in the embodiments of the present disclosure is generally performed jointly by the home appliances and the server. Accordingly, the device switching device for home appliances is generally provided in the home appliances and the server.

[0027] In the disclosed embodiments, home appliances include the current home appliance and other home appliances. The current home appliance refers to a home appliance that plays multimedia. Other home appliances refer to home appliances other than the current home appliance. A target home appliance refers to a home appliance that is not turned on and can be controlled to play multimedia.

[0028] Based on the above implementation environment, combined with Figure 2 As shown, the embodiment of the present disclosure further provides a device switching method for a home appliance, comprising: S01, the server sends a sensing instruction to multiple home appliances.

[0029] S02: The server receives the sensing results sent by multiple home appliances. The sensing results are obtained by the home appliances in response to the sensing instructions, and the sensing results include the distance between the current device and the user and the communication parameters of the current device.

[0030] S03: The server determines whether to switch the home appliance that plays multimedia based on the perception result.

[0031] Using the device switching method for home appliances provided by the embodiment of the present disclosure, in the embodiment of the present disclosure, after the server sends a perception instruction to multiple home appliances, it receives the perception results sent by the multiple home appliances, and then determines whether to execute the switching of the home appliance device that plays multimedia based on the perception results. In this way, the server that receives the perception results can determine whether to switch the home appliance device that plays multimedia based on the distance information and the communication parameters of the current device to achieve seamless switching of multimedia playback. Even if the user moves quickly in the perception scene, the user can still receive the multimedia played by the switched home appliance device, which helps to improve the user's playback experience in the perception scene.

[0032] Optionally, the server determines whether to switch the home appliance that plays multimedia based on the perception result, including: the server receives The perception results sent by home appliances; In the case of , the server determines whether to switch the home appliance that plays multimedia based on the perception result. Indicates the total number of household appliances, 0.5≤ <1, This prevents the server from waiting for all home appliances to send their sensing results, which can cause response delays.

[0033] Optionally, the communication parameters include signal strength and / or communication coverage. The server determines whether to switch the home appliance playing multimedia based on the perception result, including: The server receives the user's movement speed, current location, and movement direction.

[0034] If the user's movement speed indicates a slow movement, the server determines the target area based on the distance information, current location, and movement direction, and selects the home appliance closest to the user within the target area as the target home appliance. The home appliance closest to the user within the target area is the home appliance with the smallest distance information within the target area.

[0035] When the moving speed indicates that the user is moving at a medium speed, the server determines the target home appliance based on the signal strength and computing load of each home appliance.

[0036] When the moving speed indicates that the user is moving at a high speed, the server selects a home appliance whose signal strength meets the strength threshold condition and whose communication coverage meets the stable communication condition as the target home appliance.

[0037] The server determines to switch the multimedia playing home appliance, wherein the switching includes sending a first device instruction to the current home appliance to stop multimedia playing and sending a second device instruction to the target home appliance to start multimedia playing.

[0038] Thus, in the embodiment of the present disclosure, after the server receives the user's moving speed, current position, and moving direction, if the moving speed indicates that the user is moving at a low speed, the target area is determined based on the distance information, current position, and moving direction, and the home appliance closest to the user in the target area is selected as the target home appliance. If the moving speed indicates that the user is moving at a medium speed, the system needs to make a decision quickly. The server determines the target home appliance based on the signal strength and computing load of each home appliance. If the moving speed indicates that the user is moving at a high speed, the system needs to respond quickly. At this time, the home appliance whose signal strength meets the strength threshold condition and whose communication coverage meets the stable communication condition is selected as the target home appliance to ensure the continuity of multimedia audio. In this way, the server makes differentiated decisions based on the communication parameters carried by the received perception results when considering the user's moving speed to achieve seamless switching of multimedia playback, so that the user always gets a good playback experience during the movement.

[0039] Optionally, the user's low-speed movement is determined in the following manner: the moving speed is less than or equal to the lower speed threshold. The user's medium-speed movement is determined in the following manner: the moving speed is greater than the lower speed threshold and less than or equal to the upper speed threshold. The user's high-speed movement is determined in the following manner: the moving speed is greater than the upper speed threshold. Among them, the lower speed threshold is greater than 0 and less than or equal to 1.5m / s (meters / second), preferably, the lower speed threshold is 1m / s. The upper speed threshold is greater than 1.5m / s and less than or equal to 4m / s (meters / second), preferably, the upper speed threshold is 3m / s. It can be understood that the lower speed threshold and the upper speed threshold can also be flexibly set according to the perception scenario of the user, and no limitation is made here.

[0040] In some optional embodiments, the movement direction indicates the direction in which the user moves relative to the user's current location. The server determines the target area based on the distance information, the current location, and the movement direction, including: the server predicting the area after the user moves based on the distance information, the current location, and the movement direction; and the server determining the area after the user moves as the target area. The above-mentioned prediction method may employ any of the following algorithms: Dijkstra's algorithm, ray casting algorithm, or dead center algorithm, and is not specifically limited herein.

[0041] Optionally, combined Figure 3 As shown, the server determines the target home appliance based on the signal strength and computing load of each home appliance, including: S11, the server determines the computing load index of each home appliance according to the computing load of each home appliance.

[0042] S12, the server selects a home appliance whose signal strength meets the strength threshold condition and whose calculated load index meets the load threshold condition as the target home appliance.

[0043] In this way, the server determines the computing load index of each home appliance based on the computing load of each home appliance, and selects the home appliance whose signal strength meets the strength threshold condition and the computing load index meets the load threshold condition as the target home appliance, so that the system can make quick decisions and achieve seamless switching of multimedia playback.

[0044] In some optional embodiments, the calculation load indicator includes CPU (Central Processing Unit) occupancy or network latency. As a specific example, the calculation load indicator meets a load threshold condition, including: CPU occupancy is less than or equal to the occupancy threshold, or network latency is less than or equal to a set network latency.

[0045] Optionally, the signal strength meets a strength threshold condition, including: the signal strength is greater than or equal to a signal strength threshold, wherein the signal strength threshold represents an average value of the signal strengths sent by the home appliance and received by the server, or the signal strength threshold represents a second-largest value of the signal strengths sent by the home appliance and received by the server.

[0046] The communication coverage area meets stable communication conditions, including: the target area is within the communication coverage area. Therefore, when the server determines that the user is moving at high speed, it can select home appliances with relatively good signal strength and within the communication coverage area after the user moves as target appliances to accommodate the user's high-speed movement.

[0047] Optionally, the device switching method for a household appliance further includes: The server receives the user's movement direction.

[0048] The server determines the target direction of multimedia playback of the current home appliance based on the moving direction and adjusts the current home appliance to play multimedia in the target direction. The target direction of multimedia playback of the current home appliance refers to the multimedia playback direction after the current home appliance is rotated.

[0049] 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 of the rotated current home appliance are the same. It is understandable that if the current home appliance does not have a rotation function, the current home appliance does not perform the rotation operation.

[0050] In this way, in the embodiment of the present disclosure, by controlling the rotation of the current home appliance with a rotation function, it can be consistent with the user's movement direction, thereby ensuring the continuity of multimedia audio.

[0051] Optionally, the device switching method for a household appliance further includes: The server gradually reduces the multimedia playback volume of the current home appliance as the distance information decreases; And / or, the server gradually increases the multimedia playback volume of the target home appliance as the distance information increases.

[0052] In some optional embodiments, the smaller the moving speed, the slower the server adjusts the multimedia playback volume of the current home appliance, and the larger the moving speed, the faster the server adjusts the multimedia playback volume of the current home appliance.

[0053] In other optional embodiments, the smaller the moving speed, the slower the server adjusts the multimedia playback volume of the target home appliance, and the larger the moving speed, the faster the server adjusts the multimedia playback volume of the target home appliance.

[0054] In some optional embodiments, the first device instruction is generated by the server when the target home appliance is determined and sent to the current home appliance, and / or the second device instruction is generated by the server when the target home appliance is determined and sent to 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 at the same time to achieve seamless switching of multimedia playback.

[0055] In another specific example, after the server determines the target home appliance, it first sends the second device command to the target home appliance, and then sends the first device command to the current home appliance after a preset time interval, thereby seamlessly switching multimedia playback while preventing the user from being too far away from the current home appliance and being unable to receive the multimedia. The preset time interval is greater than zero and less than or equal to an upper threshold for the duration. The upper threshold for the duration can be a real number less than 2 seconds.

[0056] It is understandable that the preset duration can also be determined based on the sparseness of the distribution of home appliances in the scene where the user is located. For example, the more dispersed the distribution of home appliances in the scene where the user is located, the longer the preset duration, and the denser the distribution of home appliances in the scene where the user is located, the shorter the preset duration.

[0057] Combine Figure 4 As shown, the embodiment of the present disclosure further provides a device switching method for a home appliance, comprising: S21: The home appliance performs sensing in response to the sensing instruction and obtains a sensing result, wherein the sensing result includes distance information between the current device and the user and communication parameters of the current device.

[0058] S22: The home appliance sends the sensing result to the server, where the sensing result is used to determine the switching of the home appliance that plays the multimedia.

[0059] S23 , the home appliance performs switching when the server determines that the home appliance for playing multimedia is switched.

[0060] The device switching method for home appliances provided by the embodiment of the present disclosure is adopted. In the embodiment of the present disclosure, the home appliance performs perception in response to the perception instruction to obtain a perception result including distance information and the communication parameters of the current device, and then sends the perception result to the server to determine the switching of the home appliance that plays multimedia. When the server determines to execute the switching of the home appliance that plays multimedia, the home appliance executes the switching. In this way, the server that receives the perception result can determine whether to switch the home appliance that plays multimedia based on the distance information and the communication parameters of the current device to achieve seamless switching of multimedia playback. Even if the user moves quickly in the perception scene, the user can receive the multimedia played by the switched home appliance, which helps to improve the user's playback experience in the perception scene.

[0061] In some optional embodiments, the home appliance sending the perception result to the server includes: the current home appliance sending the perception result to the server, and the other home appliances sending the perception result to the server. After receiving the perception results sent by the current home appliance and the other home appliances, the server determines whether to switch the home appliance that plays the multimedia based on the perception results.

[0062] While a home appliance is transmitting a perception result used to determine the switch of the home appliance playing multimedia, if the user moves away from the current home appliance playing multimedia within the perception scenario, the volume of the multimedia received by the user gradually decreases as they move, and may even stop receiving multimedia. Based on this, in the disclosed embodiments, the perception result is also used to adjust the volume of the home appliance, achieving seamless switching of multimedia playback while also enabling adaptive control of the volume of the home appliance, further optimizing the user's playback experience within the perception scenario.

[0063] Optionally, the perception result is also used to adjust the volume of the home appliance. In some optional embodiments, the volume adjustment of the home appliance includes: the volume of the home appliance is turned up or the volume of the home appliance is turned down.

[0064] In this way, the server receiving the perception results can also adaptively adjust the volume of the current home appliance playing multimedia, so that the user in the perception scenario will not obviously feel the change in multimedia volume when moving away from the aforementioned home appliance, further optimizing the user's playback experience in the perception scenario.

[0065] Optionally, when the server determines to switch the home appliance that plays multimedia, the home appliance performs switching, including: the current home appliance stops multimedia playback in response to the first device instruction.

[0066] In this way, after the home appliance sends the perception result to the server, the current home appliance that receives the first device instruction responds to the first device instruction and stops multimedia playback, thereby achieving seamless switching of multimedia playback.

[0067] Optionally, when the server determines to switch the home appliance to play multimedia, the home appliance switches, including: the target home appliance responds to the second device instruction and starts multimedia playback. It should be noted that the target home appliance is determined by the server based on the perception result.

[0068] In this way, after the home appliance sends the perception result to the server, the target home appliance that receives the second device instruction responds to the second device instruction and stops multimedia playback, achieving seamless switching of multimedia playback. Even if the user moves quickly within the perception scene, the user can still receive the multimedia played by the home appliance after the switch, which helps to improve the user's playback experience in the perception scene.

[0069] Optionally, the device switching method for a home appliance further includes: the home appliance performs sensing in response to the sensing instruction, and before obtaining the sensing result, responding to a user instruction, activates multimedia playback. Thus, in the disclosed embodiment, before the home appliance performs sensing in response to the sensing instruction, the user sends a user instruction to the home appliance to activate multimedia playback, thereby enabling autonomous selection of the multimedia playback device.

[0070] It should be noted that, after starting multimedia playback in response to a user instruction, the process also includes: sending a notification message to the server to notify that the device is the current home appliance.

[0071] In practical applications, such as Figure 5 As shown, the device switching method for home appliances specifically performs the following steps: S31, the server sends a sensing instruction to multiple home appliances.

[0072] S32: The home appliance performs sensing in response to the sensing instruction and obtains a sensing result. The sensing result includes information about the distance between the current device and the user and the signal strength and / or communication coverage of the current device. The home appliance includes the current home appliance and other home appliances.

[0073] S33, the server receives the perception results sent by multiple home appliances.

[0074] S34, the server receives the user's moving speed, current location, and moving direction.

[0075] S35, when the moving speed is less than or equal to 1m / s, the server determines the target area based on the distance information, the current position, and the moving direction, and selects the home appliance closest to the user in the target area as the target home appliance.

[0076] S36, when the moving speed is greater than 1 m / s and less than or equal to 3 m / s, the server determines the target home appliance based on the signal strength and computing load of each home appliance.

[0077] S37, when the moving speed is greater than 3 m / s, the server selects a home appliance whose signal strength meets the strength threshold condition and whose communication coverage meets the stable communication condition as the target home appliance.

[0078] S38, the server sends a first device instruction to the current home appliance to stop multimedia playback, and sends a second device instruction to the target home appliance to start multimedia playback.

[0079] Combine Figure 6 As shown, an embodiment of the present disclosure provides a device switching apparatus 70 for a household appliance, comprising a processor 700 and a memory 701. Optionally, the apparatus 70 may further comprise a communication interface 702 and a bus 703.
