[0048] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] Please refer to Figure 1 , Figure 1 which is a flowchart of the implementation of a device offline control method provided by an embodiment of the present application. Details are as follows:

[0050] S11: When the target device is in an offline state, upload the offline state message of the target device to the cloud through any online device in the same area.

[0051] In this embodiment, the target device and the online device represent different smart home devices in the same area. For example, different smart home devices in the same smart home system, and these smart home devices can be home appliances such as smart lights, smart sockets, smart speakers, and smart sweeping robots. In this embodiment, the smart home device is a device using an IOT Wi-Fi / Ble dual-mode Combo chip.

[0052] Since there are more and more smart devices in the smart home system, the load on the router will become larger and larger, which may cause some smart home devices to disconnect from the router, or be unable to access the external network, resulting in being unable to connect to the smart home cloud service and unable to perform data communication, making the smart home device uncontrollable and unable to synchronize the status to the smart home control App (application program) on the user terminal, thus being in an offline state.

[0053] In this embodiment, in a smart home system, if a smart home device is in an offline state, that is, the smart home device is the target device. At this time, the target device can be triggered to generate an offline state message and send the offline state message to an online device, which is any smart home device that is in the same smart home system as the target device and is in an online state. Then, the online device uploads the offline state message of the target device to the cloud to inform the cloud that the target device is currently in an offline state. It can be understood that one cloud corresponds to one smart home system.

[0054] S12: In the cloud, according to the offline state message of the target device, obtain the current signal strength of all online devices in the same area. According to the current signal strength of all online devices, bind the proxy relationship between the target device and at least one online device to obtain at least one proxy device.

[0055] In this embodiment, the cloud receives the offline status message of the target device through the message channel established with the online device by adopting the Mqtt protocol. After the cloud receives the offline status message of the target device, in the cloud, the offline status message triggers the cloud to determine all the online devices in the same area as the target device, and perform signal strength detection on all the online devices in the same area as the target device to obtain the current signal strength of each online device. The current signal strength of each online device is compared one by one with the signal strength threshold preset in the cloud as the proxy condition to determine whether each online device meets the proxy condition, and then the online devices that meet the proxy condition are bound to the target device in a proxy relationship, so that the online devices that meet the proxy condition become the proxy devices of the target device. It can be understood that there can be one or more online devices that meet the proxy condition.

[0056] S13: When it is necessary to send a control instruction to the target device, the control instruction is sent to the proxy device through the message channel of the proxy device, and the proxy device is triggered to transparently transmit the control instruction to the target device.

[0057] In this embodiment, the user can perform corresponding operations on the smart home control App (application program) of the user terminal to assemble and generate a control instruction for controlling the target device. After the APP generates the control instruction, it can send the same message containing the control instruction to the target device and the proxy device at the same time through the message channel established by the target device itself and the message channel established by the proxy device that has a proxy relationship with the target device. In this way, when the target device is in the offline state, the message channel established by itself cannot send a message to the target device, and the message numbers are the same. The instruction is sent to the proxy device through the message channel established by the proxy device. After the proxy device receives the message, it triggers the proxy device to perform a transparent transmission judgment on the message. If it is judged that the message needs to be transparently transmitted, the message is assembled into a Ble message and transparently transmitted to the offline target device through Ble broadcast, so as to realize the transparent transmission of the control instruction to the target device.

[0058] Exemplarily, in this embodiment, in the smart home control App of the user terminal, the user can select several proxy devices with the best signal from the proxy devices that have a proxy relationship with the target device, preferably 2, and send the generated control signal to the target device and the two proxy devices with the best signal at the same time. Among them, the signal quality of the proxy device can be expressed as a score, and the score corresponding to each proxy device can be obtained through comprehensive calculation of the signal strength, signal stability and the distance from the target device.

[0059] As can be seen from the above, in the device offline control method provided by the embodiments of the present application, when the target device is in an offline state, the offline state message of the target device is uploaded to the cloud through any online device in the same area; in the cloud, according to the offline state message of the target device, the current signal strength of all online devices in the same area is obtained, and according to the current signal strength of all online devices, the target device is bound to at least one online device in a proxy relationship to obtain at least one proxy device; when a control instruction needs to be sent to the target device, the control instruction is sent to the proxy device through the message channel of the proxy device, and the proxy device is triggered to transparently transmit the control instruction to the target device. Based on the above method, through the device proxy method, the problems that smart home devices are often offline and uncontrollable due to the limited number of routers and that smart home devices cannot connect to the network can be solved.

[0060] In some embodiments of the present application, please refer to Figure 2 , Figure 2 which is a schematic flow chart of a method for uploading the offline state message of the target device to the cloud through any online device in the same area in the device offline control method provided by the embodiments of the present application. Details are as follows:

[0061] S21: When the target device is in an offline state, trigger the target device to perform message broadcasting and send a broadcast data packet to the online devices in the same area, where the broadcast data packet contains the offline state message of the target device;

[0062] S22: When any online device in the same area receives the broadcast data packet, trigger the online device to perform primary authentication processing on the broadcast data packet. If the authentication passes, use the message channel of the online device to transparently transmit the broadcast data packet to the cloud.

[0063] In this embodiment, the target device can be triggered to generate an offline state message, and based on this offline state message, message broadcasting is performed, and a broadcast data packet indicating that the target device is in an offline state is sent out through the Bluetooth (Ble) network. In this embodiment, the offline state message data in the broadcast data packet is encrypted using the user-level key pre-stored in the target device. It should be noted that all smart home devices in the same smart home system use the same user-level key.

[0064] In this embodiment, any online device in the same area as the target device can receive the broadcast data packet sent by the target device through the Bluetooth (Ble) network. In this embodiment, the online device that receives the broadcast data packet can be one or more. When any online device in the same area receives the broadcast data packet, it can trigger the online device that receives the broadcast data packet to perform a first-level authentication process on the broadcast data packet. Exemplarily, the first-level authentication process includes decrypting the broadcast data packet using the user-level key pre-stored in the online device. If the decryption is successful, the authentication passes; otherwise, the authentication fails. In the case where the authentication passes, the broadcast data packet is transparently transmitted to the cloud through the message channel of the online device. The message channel of the online device is a message channel established between the online device and the cloud through the Mqtt protocol for data interaction. In the case where the authentication fails, the online device is triggered to discard the broadcast data packet without uploading it.

[0065] In some embodiments of the present application, please refer to Figure 3 , Figure 3 which is a flowchart of a method for performing first-level authentication in the device offline control method provided by the embodiments of the present application. Details are as follows:

[0066] S31: Trigger the online device to detect its current signal strength to obtain a first signal strength;

[0067] S32: Compare the first signal strength with a preset signal strength threshold to determine whether the first signal strength is greater than the preset signal strength threshold. If not, directly determine that the authentication fails.

[0068] In this embodiment, a signal strength threshold can be set in the cloud as a proxy condition, and only the online devices that meet this proxy condition can proxy the offline device to perform relevant data processing. The online device can load the proxy condition from the cloud to the device local through data loading. In this embodiment, when the online device needs to perform a first-level authentication process on the broadcast data packet, it can also detect its current signal strength to obtain a first signal strength, and then compare the first signal strength with the signal strength threshold loaded by the online device to the device local to determine whether the first signal strength is greater than the signal strength threshold. If it is not greater, it means that the online device does not meet the proxy condition, and at this time, it can be directly determined that the authentication fails. If it is greater, further decrypt the broadcast data packet using the user-level key pre-stored in the online device to determine whether the authentication passes.

[0069] In some embodiments of the present application, after receiving the offline status message of the target device in the cloud, a secondary authentication process can also be performed on the target device and the online device that uploaded the offline status information of the target device to the cloud. Specifically, the first user identifier corresponding to the target device and the second user identifier corresponding to the online device are obtained from the local cloud record. The first user identifier and the second user identifier are compared to determine whether the first user identifier and the second user identifier are consistent. If they are consistent, it is determined that the target device and the online device have the same user identifier. In this case, the secondary authentication result is determined to be authentication passed. At this time, the target device can be bound to the online device in a proxy relationship. Otherwise, the cloud is triggered to discard the offline status message of the target device and abandon the proxy binding operation.

[0070] In some embodiments of the present application, after obtaining at least one proxy device in the cloud, the proxy relationship between the target device and each of the proxy devices may be stored in a preset cache in the cloud, such as a Redis cache. Furthermore, a score representing the signal strength of each proxy device is calculated based on the signal strength parameter, signal stability parameter, and distance parameter between each proxy device and the target device. The proxy devices are then sorted by score to obtain a proxy device list. It will be appreciated that in this embodiment, the user terminal can determine the proxy device to be used to issue control instructions based on the proxy device list.

[0071] In some embodiments of the present application, in the cloud, for the obtained proxy device list, the proxy device list can also be updated according to preset update rules, wherein the preset update rules may include at least one of the following rules: The first rule is that if the target device sends an unbinding request to the cloud, all binding relationships related to the target device in the proxy device list are cleared. The second rule is that if the proxy device sends an unbinding request to the cloud, the binding relationship between the proxy device and the target device is deleted from the proxy device list. The third rule is that if the cloud detects that the proxy device is offline, the binding relationship between the proxy device and the target device in the proxy device list is updated to unavailable. The fourth rule is that if the cloud detects that the binding relationship between the proxy device and the target device is unavailable and the unavailable duration reaches a preset duration threshold, the binding relationship between the proxy device and the target device is deleted.

[0072] In some embodiments of the present application, after obtaining at least one proxy device, the status of the target device can be maintained through the proxy device. Exemplarily, in this embodiment, when binding the proxy relationship between the target device and at least one online device to obtain at least one proxy device initially, it can trigger the proxy device to send a first online status change instruction to the target device, so that the target device changes its device status to the online status according to the first online status change instruction and maintains the heartbeat of the target device; and trigger the proxy device to send a second online status change instruction containing the identity information of the target device to the cloud, so that the cloud changes the device status of the target device currently recorded in the cloud to the online status according to the second online status change instruction.

[0073] Further, in this embodiment, after changing to the online status, it can trigger the proxy device to monitor the receiving duration interval of the target device status information, and when the receiving duration interval exceeds the preset interval threshold, send a first offline status change instruction to the target device, so that the target device changes its device status to the online status according to the first online status change instruction; and trigger the proxy device to monitor the receiving duration interval of the target device status information, and when the receiving duration interval exceeds the preset interval threshold, send a second offline status change instruction containing the identity information of the target device to the cloud, so that the cloud determines whether to change the device status of the target device currently recorded in the cloud to the online status according to the second offline status change instruction and other proxy devices.

[0074] It should be noted that, in this embodiment, the proxy device will report to the smart home cloud service only when the status of the target device is reversed, and maintain the heartbeat locally without reporting to the smart home cloud service when the status has not changed, thereby reducing the pressure on the smart home cloud service.

[0075] In some embodiments of the present application, after the target device receives a message containing a control instruction and when the target device processes the control instruction, it can also trigger the target device to perform message filtering processing on the received message containing the control instruction, and only retain one for the same message. In this way, it can avoid the problem of repeated processing when multiple proxy devices transparently transmit the same message to the target device.

[0076] It can be understood that the magnitudes of the sequence numbers of the above steps in the embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

The binding module 42 is used to obtain the current signal strength of all online devices in the surrounding area according to the offline status message of the target device in the cloud, and bind the target device to at least one online device in a proxy relationship according to the current signal strength of all online devices to obtain at least one proxy device. The control module 43 is used to, when a control instruction needs to be issued to the target device, issue the control instruction to the proxy device through the message channel of the proxy device, and trigger the proxy device to transparently transmit the control instruction to the target device.
