To enhance the variety of applicable application scenarios, various smart home devices integrate multiple different functions. Currently, smart home devices typically set a fixed operating frequency for their main chip to support the operation of various functions.

[0003] For battery-powered smart home devices, such as smart locks and smart doorbells, power consumption is extremely sensitive. Therefore, how to reduce power consumption while ensuring normal operation and achieving longer battery life for these devices after they are woken from standby mode has become a pressing issue.

[0030] The control method provided in the embodiments of this application is described below. The executing subject of this control method is a smart home device, which can be a battery-powered device or a plug-in device; no limitation is made here. In fact, any smart home device that has a need for power saving can serve as the executing subject of the control method in the embodiments of this application.

[0031] To facilitate understanding of the control method provided in the embodiments of this application, a description of smart home devices is given below. Smart home devices typically include a main chip and at least two functional modules, each capable of performing its own specific related functions. Please refer to... Figure 1 , Figure 1 This document provides an example of the architecture for a smart home device when it is a smart door lock. Figure 1 As shown, the functional modules of this smart home device may include: a Wireless Fidelity (Wi-Fi) module, a fingerprint recognition module, a Near Field Communication (NFC) recognition module, a touch control module, and a facial recognition module. Each functional module can be connected to a pin of the main chip, and different functional modules are connected to different pins on the main chip, thereby establishing a communication connection between each functional module and the main chip through pins, enabling each functional module to interact with the main chip.

[0032] Based on the above-mentioned architecture of smart home devices, please refer to [link / reference]. Figure 2 The control method proposed in this application includes:

[0033] Step 201: When the main chip receives an interrupt signal, determine the source module of the interrupt signal from at least two functional modules.

[0034] For a functional module, upon detecting external interaction or receiving external input commands, it can send an interrupt signal to the main chip, thereby waking it up. The main chip, upon receiving the interrupt signal, can identify the source module among all currently configured functional modules in the smart home device. The source module refers to the functional module that issued the interrupt signal, i.e., the origin of the interrupt signal. Through this interrupt signal, the source module can wake up the main chip, subsequently triggering the main chip to run algorithms related to the source module and execute corresponding decisions. For example, if the source module is a fingerprint recognition module, the main chip can then execute fingerprint recognition algorithms and determine whether unlocking is possible based on the algorithm's execution result.

[0035] In some embodiments, since each functional module establishes a communication connection with the main chip through different pins, when the main chip receives an interrupt signal, it can determine the source module of the interrupt signal in the following way: First, determine the target pin that received the interrupt signal. Then, based on the target pin, determine the source module among at least two functional modules. The main chip pre-records the functional modules corresponding to each of its pins; therefore, by querying the functional module corresponding to the target pin, the source module of the interrupt signal can be determined. That is, in this embodiment, the source module can be determined based on the one-to-one relationship between pins and functional modules.

[0036] Step 202: Determine the first target frequency based on the source module.

[0037] Different functional modules may have different operating requirements. For example, the touch module may only require the main control module to respond to user touch operations, thus simply requiring the main chip to operate at a lower frequency to save energy; the fingerprint recognition module may require the main control module to perform more complex algorithm processing, thus requiring the main chip to operate at a higher frequency to improve algorithm processing efficiency. Based on this, by analyzing the source of interrupt signals, the main chip can dynamically adjust its operating frequency.

[0038] In some embodiments, the main chip may pre-store a module-frequency mapping relationship. An example of this module-frequency mapping relationship is given in Table 1 below:

[0039] Functional modules Main chip operating frequency Fingerprint recognition module F1 NFC identification module F2 Touch module F3 Face recognition module F4 Wi-Fi module F5

[0040] Table 1

[0041] The module-frequency mapping can be set by the smart home device manufacturer according to the actual architecture of the smart home device. Based on this, the main chip can find the main chip operating frequency corresponding to the source module in the module-frequency mapping, and then determine the main chip operating frequency corresponding to the source module as the first target frequency.

[0042] Step 203: Control the main chip to work at the first target frequency after being woken up by the interrupt signal.

[0043] The source module can wake up the main chip via an interrupt signal. To achieve adaptive adjustment of the main chip's operating frequency, the main chip, after being woken up, no longer operates at a fixed frequency, but instead operates at a predetermined first target frequency. For example, based on Table 1, when the source module is a fingerprint recognition module, the first target frequency is F1, meaning the main chip will operate at frequency F1 after being woken up by the fingerprint recognition module; when the source module is an NFC recognition module, the first target frequency is F2, meaning the main chip will operate at frequency F2 after being woken up by the NFC recognition module.

[0044] In some embodiments, the state of the main chip when it receives an interrupt signal is not limited. That is, the main chip may receive the interrupt signal in standby mode; or it may receive the interrupt signal in working mode (a woken-up state). This is because in actual application scenarios, the main chip may receive interrupt signals from two or more functional modules in a short period of time. For the case where the main chip receives at least two interrupt signals within a target time period, the main chip can identify at least two source modules and compare the main chip frequencies corresponding to each source module in the module-frequency mapping relationship, and determine the largest main chip frequency as the first target frequency. That is, step 201 can be further optimized as follows: when the main chip receives at least two interrupt signals within a preset time period, the source modules of each interrupt signal are identified, thereby identifying at least two source modules; step 202 can be further optimized as follows: in the preset module-frequency mapping relationship, the main chip operating frequency corresponding to each source module is searched; and the largest main chip operating frequency found is determined as the first target frequency.

[0045] For example, at time T0, if the main chip receives an interrupt signal from the fingerprint recognition module while in standby mode, the main chip will be woken up and will operate at the F1 operating frequency as the first target frequency.

[0046] For example, based on the interrupt signal issued by the fingerprint recognition module at time T0, the main chip has completed the fingerprint recognition algorithm at time T1 and obtained the execution result of fingerprint matching failure. Based on this, the user wants to change the unlocking method from fingerprint unlocking to face unlocking. At time T2, the main chip, in its working state, receives an interrupt signal issued by the face recognition module. If F4 > F1, the main chip can switch the first target frequency from F1 to F4 and continue to work. Conversely, if F4 ≤ F1, the main chip can keep the first target frequency at F1 and continue to work.

[0047] In some embodiments, in addition to adaptively adjusting the operating frequency of the main chip to reduce power consumption, the operating frequency of each functional module can also be controlled to reduce its own power consumption. This further reduces the power consumption of smart home devices without affecting the user experience. It is understood that, to achieve low power consumption, from a microscopic perspective, each functional module operates periodically. For example, the touch module operates at a frequency of 5Hz, meaning that every 200 milliseconds, the touch module wakes up from sleep mode to scan, at which point it is truly working. After working for a short period (approximately tens of milliseconds), it enters sleep mode again and scans again after another 200 millisecond interval. It should be noted that the operating frequency of the functional modules described here is actually a broad concept; depending on the functional module, this operating frequency can be further refined into scanning frequency and keep-alive cycle, etc., which will not be elaborated here. Please refer to [link to relevant documentation]. Figure 3 The control method proposed in the embodiments of this application may further include:

[0048] Step 301: Periodically count the number of times each functional module wakes up the main chip within the statistical time period.

[0049] The statistical time period refers to a time period with a preset statistical end time and a cycle duration. For example, the cycle duration can be 24 hours, and the statistical time can be 0:00 every day, meaning the main chip can count the number of times each functional module wakes up the main chip in the previous day at 0:00 every day. Another example is a 7-day cycle, with the statistical time being 0:00 every Monday, meaning the main chip can count the number of times each functional module wakes up the main chip in the previous week at 0:00 every Monday.

[0050] Step 302: Control the working frequency of each functional module according to the number of wake-ups corresponding to each functional module.

[0051] Based on the number of wake-ups corresponding to each functional module, smart home devices can determine the recent activity level of each module. Furthermore, a positive correlation can be established between the activity level and the operating frequency of each module, thereby controlling its operating frequency. That is, a functional module with a higher number of wake-ups is relatively more active, and its operating frequency can be kept at a relatively high level; conversely, a functional module with a lower number of wake-ups is relatively less active, and its operating frequency can be kept at a relatively low level.

[0052] In some embodiments, to achieve reasonable control over the operating frequency of the functional module, step 302 may include:

[0053] A1. If the number of wake-up attempts for the module to be controlled is less than the preset threshold, reduce the operating frequency of the module to be controlled.

[0054] The preset threshold number can be initially set by the smart home device manufacturer and can be subsequently changed by the user according to actual needs; this is not limited here. When the number of wake-ups corresponding to the module to be controlled is less than the preset threshold number, the smart home device can reduce the operating frequency of the module to be controlled to a fixed value; alternatively, it can linearly and gradually reduce the operating frequency of the module to be controlled; or it can non-linearly and gradually reduce the operating frequency of the module to be controlled; this embodiment does not limit this. The module to be controlled can be any functional module; that is, for each functional module, relevant processing can be performed through steps A1 and A2.

[0055] Specifically, smart home devices can linearly and gradually reduce the operating frequency of the modules to be controlled in the following way:

[0056] First, the target duration is updated based on multiple consecutive statistical time periods where the number of wake-ups corresponding to the module to be controlled is less than a preset threshold. The target duration refers to the consecutive periods during which the number of wake-ups corresponding to the module to be controlled is less than the preset threshold.

[0057] Taking a period of 24 hours, a statistical time of 0:00 every day, and a preset threshold of 1 time as an example, if the number of wake-ups corresponding to the NFC recognition module has been found to be 0 for three consecutive times (that is, the number of wake-ups corresponding to the NFC recognition module has been 0 for the most recent three days), then the target duration can be updated to three days.

[0058] Then, the second target frequency is calculated based on the target duration, the preset aging duration, the preset lower limit of the operating frequency, and the preset default value of the operating frequency.

[0059] As an example only, the formula for calculating the second target frequency can be: F n =F0-(F0-F m )*N / M. Where, F n This indicates the second target frequency, F0 represents the default operating frequency, and F... mThe values ​​represent the lower limit of the operating frequency, N represents the target duration, and M represents the aging time. The aging time, lower limit of the operating frequency, and default operating frequency can all be determined based on the module to be controlled. That is, different aging times, lower limits of the operating frequency, and default operating frequencies can be configured for different modules. Furthermore, users can adjust the aging time, lower limit of the operating frequency, and / or default operating frequency according to their needs. Considering that users are not professional R&D personnel, this embodiment of the application may provide users with parameter value configuration items for different power-saving levels in the parameter configuration interface of the application associated with the smart home device; in this way, users only need to select their desired power-saving level to adjust the corresponding parameters.

[0060] Finally, the module to be controlled is controlled to operate at the second target frequency.

[0061] In other words, smart home devices can adjust the operating frequency of the module to be controlled to a second target frequency, so that the module to be controlled can operate at the reduced operating frequency.

[0062] It is important to note that after updating the consecutive counts of the target statistical time period, if the target duration exceeds the aging duration, there is no need to calculate the second target frequency again, and the module under control can be directly controlled to operate at the lower limit of the operating frequency. That is, the second target frequency must not be lower than this lower limit of the operating frequency.

[0063] In some application scenarios, the minimum operating frequency limit mentioned above can be configured to 0. This could lead to a situation where a certain functional module's operating frequency drops to 0 due to prolonged inactivity in waking the main chip, effectively shutting down the module. In such cases, the user needs to manually trigger the disabled module, for example, by manually waking up the smart home device's control panel to power on and activate all functional modules.

[0064] A2. If the number of wake-up attempts corresponding to the module to be controlled is greater than or equal to the preset threshold, restore the operating frequency of the module to the preset default value.

[0065] If the number of wake-ups corresponding to the module to be controlled is greater than or equal to the preset number, it indicates that the module to be controlled has been relatively active in the recent statistical period. Based on this, it can be inferred that due to the inertia of user behavior, the module to be controlled is likely to remain active in the current new statistical period. In response, smart home devices can restore the operating frequency of the module to be controlled to the preset default operating frequency.

[0066] As can be seen from the above, in this embodiment, after the main chip receives an interrupt signal, the smart home device can adjust the operating frequency of the main chip after it is woken up according to the functional module that issued the interrupt signal. In this way, after the main chip is woken up, its operating frequency can adapt to the relevant algorithm requirements of the functional module, meaning its operating frequency is no longer fixed at a higher frequency. Through the above operation, excessive redundant power consumption after the main chip is woken up is avoided, thus extending the battery life of the smart home device.

[0067] Corresponding to the control method provided above, this application also provides a control device.

[0086] The first control subunit is used to control the module to be controlled to operate at the second target frequency.

[0087] In some embodiments, the reducing unit further includes:

[0088] The second control subunit is used to control the module to be controlled to operate at the lower limit of the operating frequency when the target duration exceeds the aging duration.

[0089] As can be seen from the above, in this embodiment, after the main chip of the smart home device receives an interrupt signal, the smart home device can adjust its operating frequency after being woken up according to the functional module that issued the interrupt signal. In this way, after being woken up, the operating frequency of the main chip can adapt to the relevant algorithm requirements of the functional module, meaning its operating frequency is no longer fixed at a higher frequency. Through the above operation, excessive redundant power consumption is avoided after the main chip is woken up, thus extending the battery life of the smart home device.

[0090] Corresponding to the control method provided above, this application also provides a smart home device. Please refer to...

Specifically, the processor 502 performs the following steps by running the computer program stored in the memory 501:
