[0030] The control method provided in the embodiment of the present application is described below. The execution subject of the control method is a smart home device, which can be a battery-powered device or a plug-in device, which is not limited here. In fact, as long as there is a need to save power consumption, the smart home device can be used as the execution subject of the control method in the embodiment of the present application.

[0031] To facilitate understanding of the control method provided in the embodiments of the present application, the following first introduces the smart home device. The smart home device generally includes a main chip and at least two functional modules, wherein each functional module can perform its own unique related functions. Figure 1 , Figure 1 The following is an example of the architecture of a smart home device when the smart home device is a smart door lock. Figure 1 As shown, the functional modules of the smart home device may include: wireless network (Wireless Fidelity, Wi-Fi) module, fingerprint recognition module, near field communication (Near Field Communication, NFC) recognition module, touch module and face recognition module. Each functional module can be connected to a pin of the main chip, and different functional modules are connected to different pins of the main chip, so that each functional module can communicate with the main chip through the pins.

[0032] Based on the above proposed smart home device architecture, please refer to Figure 2 , the control method proposed in the embodiment of the present application includes:

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

[0034] For the functional module, when it detects external interactive operations or receives external input instructions, it can send an interrupt signal to the main chip to wake up the main chip. For the main chip, when it receives an interrupt signal, it can determine the source module of the interrupt signal among all the functional modules currently configured in the smart home device. Among them, the source module refers to: the functional module that sends an interrupt signal, that is, the source of the interrupt signal. Through the interrupt signal, the source module can wake up the main chip, thereby triggering the main chip to run the algorithm related to the source module and execute the corresponding decision. For example, when the source module is a fingerprint recognition module, the main chip can subsequently execute the fingerprint recognition algorithm, etc., and determine whether it can be unlocked based on the algorithm 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 specifically determine the source module of the interrupt signal in the following manner: First, determine the target pin that receives the interrupt signal. Then, based on the target pin, determine the source module in at least two functional modules. Among them, the main chip pre-records the functional modules corresponding to each of its pins, so by querying the functional module corresponding to the target pin, the source module of the interrupt signal can be known. That is, in the embodiment of the present application, the source module can be determined based on the one-to-one relationship between the pin and the functional module.

[0036] Step 202: determine a first target frequency based on a source module.

[0037] Different functional modules may have different working requirements. For example, the touch module may only need the main control module to respond to the user's touch operation, so it is only necessary to simply require the main chip to run at a lower frequency to save energy; the fingerprint recognition module may need the main control module to perform more complex algorithm processing, so the main chip is required to run at a higher frequency to improve the efficiency of algorithm processing. Based on this, by analyzing the source of the interrupt signal, 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 the module-frequency mapping relationship is given below in Table 1:

[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 comparison relationship can be set by the manufacturer of the smart home device 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 comparison relationship, 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 operate at the first target frequency after being awakened by the interrupt signal.

[0043] The source module can wake up the main chip through an interrupt signal. In order to achieve adaptive adjustment of the operating frequency of the main chip, the main chip will no longer work at a fixed frequency after being awakened, but will work at a determined first target frequency. For example, based on Table 1, when the source module is a fingerprint recognition module, the first target frequency is F1, that is, the main chip will work at the operating frequency of F1 after being awakened by the fingerprint recognition module; when the source module is an NFC recognition module, the first target frequency is F2, that is, the main chip will work at the operating frequency of F2 after being awakened by the NFC recognition module.

[0044] In some embodiments, the state of the main chip when the main chip receives the interrupt signal is not limited. That is, the main chip may receive an interrupt signal in a standby state; or, it may receive an interrupt signal in a working state (a state that has been awakened). This is because in actual application scenarios, the main chip may continuously receive interrupt signals issued by more than two functional modules in a short period of time. In view of the situation that the main chip receives at least two interrupt signals within the target time period, the main chip can determine at least two source modules accordingly, and compare the main chip frequencies corresponding to each source module in the module-frequency comparison 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 determined respectively, thereby determining at least two source modules; step 202 can be further optimized as follows: in the preset module-frequency comparison relationship, the main chip operating frequency corresponding to each source module is searched respectively; the maximum main chip operating frequency obtained by the search is determined as the first target frequency.

[0045] For example, at time T0, the main chip receives an interrupt signal from the fingerprint recognition module in the standby state. After the main chip is awakened, it will operate at the operating frequency F1 as the first target frequency.

[0046] For another example, based on the interrupt signal sent by the fingerprint recognition module at time T0, the main chip has completed the execution of the fingerprint recognition algorithm at time T1, and obtained the execution result of fingerprint matching failure; based on this, the user expects to change the unlocking method from fingerprint unlocking to face unlocking, then at time T2, the main chip receives the interrupt signal sent by the face recognition module in the working state; when F4>F1, the main chip can switch the first target frequency from F1 to F4 and continue to work, conversely, when 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 the power consumption of each functional module; thereby, the power consumption of smart home devices can be further reduced without affecting the actual user experience. It can be understood that in order to achieve low power consumption, from an actual microscopic scale, each functional module works periodically. For example, the operating frequency of the touch module itself is 5Hz, which means that every 200 milliseconds, the touch module will wake up from sleep to scan. Only then is it really working, and after working for a short period of time (about tens of milliseconds), it will enter sleep again and scan again after an interval of 200 milliseconds. It should be noted that the operating frequency of the functional modules described here is actually a concept of a larger range; depending on the functional module, the operating frequency can be further refined into scanning frequency and keep-alive period, etc., which will not be elaborated here. Please refer to Figure 3 , the control method proposed in the embodiment of the present application may also include:

[0048] Step 301 , periodically counting the number of times each functional module wakes up the main chip within a statistical time period.

[0049] Among them, the statistical time period refers to: a time period with a preset statistical time as the end time and a cycle duration as the statistical duration. For example, the cycle duration can be 24 hours, and the statistical time can be 0:00 every day, that is, the main chip can count the number of wake-up times of each functional module waking up the main chip in the previous day at 0:00 every day. For another example, the cycle duration can be 7 days, and the statistical time can be 0:00 every Monday, that is, the main chip can count the number of wake-up times of each functional module waking up the main chip in the previous week at 0:00 every Monday.

[0050] Step 302: Control the operating frequency of each functional module according to the wake-up times corresponding to each functional module.

[0051] According to the wake-up times corresponding to each functional module, the smart home device can determine the activity level of each functional module in the recent period. On this basis, the activity level of the functional module can be set to be positively correlated with the working frequency of the functional module, thereby controlling the working frequency of each functional module. In other words, a functional module with a large number of wake-up times is relatively active, so the working frequency of the functional module can be controlled to be maintained at a relatively high level; conversely, a functional module with a small number of wake-up times is relatively inactive, so the working frequency of the functional module can be controlled to be maintained at a relatively low level.

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

[0053] A1. When the wake-up times corresponding to the module to be controlled are less than a preset times threshold, the working frequency of the module to be controlled is reduced.

[0054] The preset number threshold can be initially set by the manufacturer of the smart home device, and can be subsequently changed by the user according to actual needs, which is not limited here. When the number of wake-up times corresponding to the module to be controlled is less than the preset number threshold, the smart home device can reduce the operating frequency of the module to be controlled to a fixed value; or, it can also linearly and gradually reduce the operating frequency of the module to be controlled; or, it can also nonlinearly and gradually reduce the operating frequency of the module to be controlled, which is not limited in the embodiment of the present application. Among them, the module to be controlled can be any functional module; that is, for each functional module, relevant processing can be performed through step A1 and step A2.

[0055] Specifically, the smart home device can linearly and gradually reduce the operating frequency of the module to be controlled in the following manner:

[0056] First, according to a plurality of consecutive statistical time periods in which the wake-up times corresponding to the module to be controlled are less than a preset number threshold, the target duration is updated. The target duration refers to the consecutive duration in which the wake-up times corresponding to the module to be controlled are less than the preset number threshold.

[0057] Taking a cycle duration of 24 hours, a statistical time of 0:00 every day, and a preset threshold of 1 as an example, assuming that the number of wake-up times corresponding to the NFC identification module has been found to be 0 for three consecutive times (that is, the number of wake-up times corresponding to the NFC identification module has been 0 in the last three days), the target duration can be updated to three days.

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

[0059] As an example only, the calculation formula of the second target frequency may be: F n =F0-(F0-F m )*N / M. Among them, F n Indicates the second target frequency, F0 indicates the default operating frequency, F mRepresents the lower limit of the operating frequency, N represents the target duration, and M represents the aging duration. Among them, the aging duration, the lower limit of the operating frequency and the default value of the operating frequency can all be determined according to the module to be controlled. That is, different aging durations, lower limits of the operating frequency and default values ​​of the operating frequency can be configured for different modules to be controlled. In addition, the user can adjust the aging duration, the lower limit of the operating frequency and / or the default value of the operating frequency according to their needs. Taking into account that the user is not a professional R&D personnel, the embodiment of the present application may consider providing the user with parameter value configuration items of different power saving levels in the parameter configuration interface of the application associated with the smart home device; in this way, the user only needs to select the 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] That is, the smart home device may adjust the operating frequency of the module to be controlled to the second target frequency, so that the module to be controlled operates at the reduced operating frequency.

[0062] It should be noted that after updating the continuous number of target statistical time periods, if the target duration exceeds the aging duration, there is no need to calculate the second target frequency, and the module to be controlled can be directly controlled to operate at the lower limit of the operating frequency. That is, the second target frequency cannot be lower than the lower limit of the operating frequency.

[0063] In some application scenarios, the lower limit of the operating frequency mentioned above can be configured as 0 at the lowest. In this case, a certain functional module may not wake up the main chip for a long time, resulting in its operating frequency being reduced to 0, that is, the functional module is turned off. In this case, the user needs to manually trigger the turned-off functional module, for example, the user manually wakes up the panel of the smart home device, thereby triggering each functional module to power on.

[0064] A2. When the wake-up times corresponding to the module to be controlled are greater than or equal to a preset times threshold, the working frequency of the module to be controlled is restored to a preset working frequency default value.

[0065] When the number of wake-up times corresponding to the module to be controlled is greater than or equal to the preset number, it indicates that the module to be controlled is relatively active in the most recent statistical time period. Based on this, it can be inferred that due to the inertia of the user's behavior, the module to be controlled is likely to remain active in the current new statistical time period. In this regard, the smart home device 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 the embodiment of the present application, after the main chip receives the interrupt signal, the smart home device can adjust the working frequency of the main chip after it is awakened according to the functional module that sends the interrupt signal. In this way, after the main chip is awakened, its working frequency can be adapted to the relevant algorithm requirements of the functional module, that is, its working frequency is no longer fixed to a higher frequency. Through the above operation, excessive redundant power consumption is avoided after the main chip is awakened, and the battery life of the smart home device can be extended.

[0067] Corresponding to the control method provided above, the embodiment of the present application further provides a control device. The control device can be integrated into a smart home device, which includes a main chip and at least two functional modules, which will not be described in detail here.

[0082] The recovery unit is used to restore the working frequency of the module to be controlled to a preset working frequency default value when the number of wake-up times corresponding to the module to be controlled is greater than or equal to a preset number threshold.

[0083] In some embodiments, the lowering unit comprises:

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

[0087] In some embodiments, the lowering unit further comprises:

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

[0089] As can be seen from the above, in the embodiment of the present application, after the main chip of the smart home device receives the interrupt signal, the smart home device can adjust its working frequency after being awakened according to the functional module that sends the interrupt signal. In this way, after the main chip is awakened, its working frequency can be adapted to the relevant algorithm requirements of the functional module, that is, its working frequency is no longer fixed to a higher frequency. Through the above operation, excessive redundant power consumption is avoided after the main chip is awakened, and the battery life of the smart home device can be extended.

[0090] Corresponding to the control method provided above, the present application embodiment also provides a smart home device.

Figure 5 The memory 501 is used to store software programs and units, and the processor 502 executes various functional applications and controls by running the software programs and units stored in the memory 501 to obtain the resources corresponding to the above-mentioned preset events. Specifically, the processor 502 implements the following steps when running the computer program stored in the memory 501:
