Description

Technical Field

[0001] The embodiments of the present invention relate to the field of smart home technology, and in particular to a smart home linkage method, device, computer equipment and storage medium. Background Technology

[0002] With the increasing prevalence of smart homes, consumers' demand for automatic cross-device linkage is growing. Current mainstream solutions heavily rely on home Wi-Fi networks and cloud servers to implement device linkage logic. This approach is highly dependent on the network and has low reliability. The entire linkage link must pass through a home router and an internet cloud server; any interruption in any link (such as router failure, network fluctuations by the ISP, or cloud service outages) will lead to linkage failure and a poor user experience. Furthermore, because data must undergo long-distance, multi-hop transmission via "device-router-cloud server-router-device," there is a perceptible delay (typically on the order of seconds) between triggering and execution. Additionally, users typically need to configure a stable home wireless network and may need to purchase an additional central gateway, which increases the system's deployment complexity, usage threshold, and overall cost. Moreover, sensitive data such as device status and user behavior need to be uploaded to third-party cloud servers for analysis and processing, posing risks of data leakage, misuse, or attacks, and failing to adequately guarantee user privacy and security.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processes, many of these steps can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the steps can be rearranged. The process can be terminated when its operation is complete, but may also have additional steps not included in the figures. The process can correspond to a method, function, procedure, subroutine, subroutine, etc.

[0022] Example 1 Figure 1 This is a flowchart of a smart home linkage method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where multiple devices are linked and controlled in the absence of a network. The smart home linkage method provided in this embodiment is used to control the linkage of a first device and a second device, wherein the first device and the second device communicate on a preset frequency channel. Figure 1 As shown, the method specifically includes the following steps: S11. The first device controls the sending of a trigger signal corresponding to the detected event signal based on the detected event signal.

[0023] S12. The second device determines whether to execute the linkage task based on the received trigger signal and a preset linkage rule.

[0024] Specifically, the first device can be used as a trigger device, and the second device can be used as an execution device. The trigger device can be any device that needs to detect trigger events. For example, a smart toilet can be used to detect the sitting event, and a smart bathroom heater can be used to detect the presence of people, etc. Preset linkage rules corresponding to linkage scenarios can be preconfigured locally on the trigger device to determine target trigger events according to the preset linkage rules and perform real-time detection. When an event signal corresponding to the target trigger event is detected, a corresponding trigger signal can be generated and broadcast through a preset frequency channel, so that the target execution devices in the surrounding corresponding linkage scenarios can execute corresponding target linkage tasks according to the monitored trigger signal. Among them, the same device can be used as both a trigger device and an execution device according to the linkage scenario. Preferably, the preset frequency channel includes a 2.4G channel. The trigger device and the execution device are directly connected through a 2.4G private protocol, getting rid of the dependence on the cloud network and the central gateway. It can still work stably and reliably in an environment without network or with unstable network, and can greatly reduce the end-to-end delay from event trigger to action execution, realizing near-real-time local linkage response. At the same time, it simplifies the deployment architecture of the linkage system, reduces the dependence on the user's home network environment, realizes plug-and-play linkage with no configuration or minimal configuration, and also avoids the device status and linkage control data of the user from flowing through an external server, thus enhancing user privacy and data security at the architecture level. Optionally, the preset frequency channel can also use channels such as 4G and 5G to achieve the transmission of more data signals.

[0025] The execution device can be any device that needs to be used for linkage control. For example, when the execution condition is met, the smart bathroom heater turns on the warm air, and when the execution condition is met, the smart toilet turns on the seat heating, etc. Preset linkage rules can be preconfigured locally on the execution device to indicate what kind of linkage control needs to be performed under what conditions. During use, the execution device can continuously monitor the preset frequency channel. After receiving the trigger signal, it can determine whether to execute the linkage task according to the trigger signal and based on the preset linkage rules.

[0026] In an optional implementation manner, when the second device determines whether to execute the linkage task according to the received trigger signal and based on the preset linkage rules, it includes: if the second device receives the trigger signal of the preset frequency channel, then match the trigger signal with the preset linkage rules; if the second device successfully matches the target rule, then execute the linkage task.

[0027] Specifically, upon receiving a trigger signal, the second device activates its local rule matching engine to match the trigger signal with pre-stored linkage rules. If a match is successful, the linkage task corresponding to the matched target rule is executed. Through this "rule pre-storage, local matching" execution architecture, the entire matching and execution process is completed within the second device, without needing to communicate with any external devices. This effectively offloads and solidifies the linkage logic judgment function from the cloud or gateway to the local device, thus achieving a localized device linkage solution that is independent of external networks, simple to deploy, fast-responding, and protects user privacy.

[0028] Optionally, after executing the linkage task, the method further includes: if the linkage task continues to execute for more than a preset time, then stop execution. This is to avoid false detections causing the device to continue working, thereby balancing comfort and energy conservation. For example, when the smart bathroom heater controlled by the linkage is turned on and working continuously for 1 hour, the heater will automatically turn off.

[0029] In an optional implementation, the trigger signal includes a device identifier and trigger event information. Specifically, the device identifier may be the local MAC address, used by the second device to determine whether the trigger is from a specified device. The trigger event information may include event type and event value, used by the second device to determine whether a specified trigger event has occurred. When the second device performs matching, the corresponding target linkage task is only triggered locally when the device identifier and trigger event information in the received signal are completely consistent with the target rule in the stored preset linkage rules. Specifically, the device identifier can be verified first, followed by the trigger event information. This two-level filtering mechanism implements a lightweight signal filtering and matching logic, ensuring the accuracy and reliability of linkage triggering in a multi-device environment and avoiding false triggers.

[0030] Optionally, the trigger event information of the first device includes a sitting signal and / or a leaving signal, and the preset linkage rules include executing a ventilation task based on the sitting signal and / or executing a ventilation task based on the leaving signal. The linkage task of the second device includes starting ventilation and / or stopping ventilation. Specifically, the first device can be a smart toilet, and the second device can be a smart bathroom heater. For example, when the smart toilet detects a sitting event, it generates a trigger signal and broadcasts it. Upon hearing this trigger signal, the smart bathroom heater automatically starts ventilation to expel stale air from the room to the outdoors. When the smart toilet detects a leaving event, it generates a trigger signal and broadcasts it. Upon hearing this trigger signal, the smart bathroom heater automatically stops ventilation and starts blowing air for 5 minutes to sterilize the air in the room. Additionally, a protection mechanism can be added, such as limiting the duration of the ventilation and blowing processes to no more than one hour, thus balancing comfort and energy conservation.

[0031] Optionally, the step of executing the ventilation shutdown task based on the exit signal includes: initiating ventilation shutdown after a preset time following the occurrence of the exit signal. Specifically, the duration of continued ventilation can be specified to ensure ventilation effectiveness. For example, after the smart bathroom heater detects the trigger signal generated by the smart toilet based on the exit event, it maintains ventilation for 5 minutes and then automatically shuts off the ventilation.

[0032] An exemplary linkage control process is as follows: Figure 2 As shown, when a user enters the bathroom, the smart bathroom heater detects a human presence. If the current room temperature is less than 15°C, it generates a trigger signal and broadcasts it to control the smart toilet to heat the seat. It can also control itself to turn on the bathroom heater's warm air. If the human presence signal disappears for 2 minutes, it generates a trigger signal and broadcasts it to control the smart toilet to turn off the seat heating. It can also control itself to turn off the bathroom heater's warm air.

[0033] Another exemplary linkage control process is as follows: Figure 3 As shown, when the smart toilet detects a sitting event, it can generate a trigger signal and broadcast it to control the smart bathroom heater to turn on ventilation. At the same time, if the current room temperature is greater than 28°C, it generates a trigger signal and broadcasts it to control the smart bathroom heater to turn on the blower. Subsequently, if the sitting signal disappears for 2 minutes, it generates a trigger signal and broadcasts it to control the smart bathroom heater to turn off the blower and ventilation.

[0034] Based on the above technical solution, optionally, before the first device controls the sending of a trigger signal corresponding to the detected event signal, the method further includes: the mobile terminal communicating with at least the first device and the second device within a preset distance, generating the preset linkage rule based on user configuration, and sending it to the first device and / or the second device.

[0035] Specifically, preset linkage rules can be configured and sent by users via mobile terminals. Once received, the devices can permanently store these rules, enabling more customized linkage scenarios. Mobile terminals, such as smartphones and tablets, can communicate with smart home devices via Bluetooth. Both the first and second devices can have built-in dual-mode wireless communication chips supporting Bluetooth and a proprietary 2.4G protocol. By employing a dual-channel division of labor mechanism of "Bluetooth configuration, 2.4G execution," the characteristics of the two wireless technologies are utilized. Bluetooth leverages its low power consumption and convenient connection to mobile devices for complex short-range configurations, while the 2.4G proprietary protocol leverages its high transmission efficiency and good penetration for long-distance, low-latency trigger signal broadcasting between devices. The two technologies have clear division of labor and work together efficiently. Furthermore, the first and second devices can also be controlled using their respective remote controls. An example system structure for a single linkage scenario is as follows: Figure 4 As shown.

[0036] Optionally, generating the preset linkage rules based on user configuration includes: opening the control page of a target device based on user selection, wherein the target device includes at least a first device or a second device; determining a target linkage scenario based on user selection and entering the corresponding linkage configuration page; determining the linkage device and linkage parameters based on user configuration, and generating a scenario configuration according to the linkage device and the linkage parameters; and generating the preset linkage rules according to the scenario configuration and device roles.

[0037] Specifically, users can configure the linkage through target applications such as WeChat mini-programs or dedicated apps on their mobile devices. After launching the target application, it can automatically scan for available devices in the vicinity and display a list of available devices for the user to choose from. After selecting a target device, the user can enter the control page of that target device. The control page can provide pre-selected linkage scenarios, and users can also add their own. Users can click to select a target linkage scenario, such as "Cool Toilet Use in Summer," which will take them to the corresponding linkage configuration page. The linkage configuration page can display a list of devices and tasks that can be linked with the target device. Users can choose to bind linkage devices and linkage tasks, and can click to enter the linkage task page to modify relevant parameters and actions. For example, the trigger condition and execution action of the linkage task can be configured separately. For instance, the trigger condition is that the smart toilet senses a sitting event, and the execution action is that the smart bathroom heater starts ventilation.

[0038] After the user completes the configuration, a scene configuration can be automatically generated based on the corresponding linked devices and parameters, specifically a JSON configuration. Then, based on this scene configuration and the device roles of the relevant devices (e.g., the target device can act as the trigger device, and linked devices as the execution devices), corresponding preset linkage rules can be generated and sent to the corresponding devices via Bluetooth. Configuration can be completed simply by scanning a QR code or bringing the device close to the user's phone, offering high user-friendliness and a simpler configuration process.

[0039] The technical solution provided in this invention is used to control the linkage of a first device and a second device. The first device, based on a detected event signal, controls the sending of a trigger signal corresponding to the event signal; the second device, based on the received trigger signal and a preset linkage rule, determines whether to execute a linkage task; wherein the first device and the second device communicate on a preset frequency channel. By performing local matching in real time through pre-stored rules and communicating directly between devices through a specified frequency channel, fully offline localized device linkage is achieved, unaffected by home networks or internet status, and still usable in offline environments, significantly improving linkage reliability. Furthermore, linkage latency can be reduced from seconds to milliseconds, resulting in a more seamless and smooth user experience, while also simplifying deployment. Device status and user behavior data only need to be transmitted point-to-point between devices, eliminating the risk of cloud privacy leaks.

[0040] Example 2 Embodiment 2 of the present invention also provides a smart home linkage method, which is applicable to the linkage control of multiple devices under offline conditions. The smart home linkage method provided in this embodiment is applied to a second device as the execution terminal device, and the method specifically includes the following steps: Based on the received trigger signal and the preset linkage rules, determine whether to execute the linkage task; The second device receives signals from a preset frequency channel.

[0041] This embodiment of the smart home linkage method broadcasts a trigger signal via a preset frequency channel, enabling execution devices in the surrounding linkage scenarios to receive the signal. The second device executes the corresponding target linkage task based on the detected trigger signal. Preferably, the preset frequency channel includes a 2.4G channel. The execution devices connect directly via a 2.4G proprietary protocol, eliminating reliance on cloud networks and central gateways. This allows for stable and reliable operation even in environments without or with unstable networks. Furthermore, it significantly reduces end-to-end latency from event triggering to action execution, achieving near real-time local linkage response. Simultaneously, it simplifies the deployment architecture of the linkage system, reduces dependence on the user's home network environment, and enables plug-and-play linkage with minimal or no configuration. Additionally, it avoids the flow of user device status and linkage control data through external servers, thereby improving user privacy and data security at the architectural level. Optionally, the preset frequency channel can also use 4G, 5G, or other channels to enable the transmission of more data signals. Optionally, the trigger event information includes sitting signals, leaving signals, shower signals, etc., and the preset linkage rules include executing a ventilation task based on the sitting signal and / or executing a ventilation task based on the leaving signal. The linkage tasks of the second device include starting ventilation and / or stopping ventilation. For example, the second device is a smart bathroom heater. When the smart toilet detects a sitting event, it generates a trigger signal and broadcasts it. Upon hearing this trigger signal, the smart bathroom heater automatically starts ventilation to expel stale air from the room to the outdoors. When the smart toilet detects a leaving event, it generates a trigger signal and broadcasts it. Upon hearing this trigger signal, the smart bathroom heater automatically stops ventilation and turns on the blower for 5 minutes to ventilate or sterilize the air in the room. The user operates the device without being aware of its surroundings, and the device automatically ventilates the ambient air and can automatically stop within a preset time period, avoiding the need for the user to constantly turn on the ventilation control when entering and leaving, thus improving the user experience.

[0042] Example 3 Embodiment 3 of the present invention also provides a smart home linkage device, which includes: The first device is used to control the transmission of a trigger signal corresponding to the detected event signal based on the event signal. The second device is used to determine whether to execute a linkage task based on the received trigger signal and a preset linkage rule.

[0043] Optionally, the device further includes: A mobile terminal is configured to communicate with at least the first device and the second device within a preset distance, generate the preset linkage rules based on user configuration, and send them to the first device and / or the second device.

[0044] The smart home linkage device provided in this embodiment can execute the smart home linkage method provided in any embodiment of the present invention. The execution method can provide a localized device that does not rely on external networks, is simple to deploy, responds quickly, and can protect user privacy in practical application scenarios, such as bathrooms, basements, and other areas with poor network signals, or due to concerns about network stability, installation complexity, and data privacy.
