[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with embodiments.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG is a hardware structure diagram of a mobile terminal according to a module wake-up method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown) a processor 102 (the processor 102 may include but is not limited to a microprocessor MCU or a programmable logic device FPGA and other processing devices) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It will be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0029] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the module wake-up method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, implementing the above-mentioned method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0030] The transmission device 106 is used to receive or send data via a network. A specific example of the aforementioned network may include a wireless network provided by the mobile terminal's communications provider. In one embodiment, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0031] In this embodiment, a module wake-up method running on the above mobile terminal or network architecture is provided. Figure 2 This is the process of the module wake-up method according to an embodiment of the present invention. Figure 1 ,like Figure 2 As shown, the process includes the following steps:

[0032] Step S202: When the wake-up time delivery condition is met, determining the remaining call time of each functional module, wherein the remaining call time indicates the remaining time between the next call time of the functional module and the current time;

[0033] Step S204, based on the remaining call time of each of the functional modules, determining a functional module with the shortest remaining call time among the multiple functional modules as a target functional module;

[0034] Step S206: Determine a target wake-up time based on the next time the target functional module is called, and send the target wake-up time to the hardware timer to instruct the hardware timer to wake up the target module when the target wake-up time arrives. After the target module sends the target wake-up time to the hardware timer, the target module enters a sleep state.

[0035] For example, Figure 3 FIG. 1 is a schematic diagram of module distribution according to a module wake-up method according to an embodiment of the present invention. Figure 3As shown, in an optional embodiment, the camera device includes one or more business modules, each of the business modules includes one or more sub-modules (i.e., the target module mentioned above), and each of the sub-modules includes one or more functional modules. Exemplarily, the multiple functional modules in the target module reuse the timer, and after being awakened, the target module calls the functional module that reaches the reporting time (for example, the target module calls the corresponding interface of the functional module through the callback function corresponding to the functional module), wherein one or more functional modules need to report information to the target platform regularly, the timer is integrated in the target module, and the registration information of one or more functional modules is recorded in the target module, and the registration information includes: the time of successful registration of the functional module, the reporting period of the functional module, and the timestamp of the most recent report of the functional module. Exemplarily, when the trigger condition is met, the functional module sends a registration request to the target platform for the first time through the corresponding interface in the target module. If the registration is successful, the target module records the time of successful registration. If the registration is unsuccessful, the target module instructs the timer to wake up the target module after the reporting period from the current time to request registration of the functional module to the target platform again.

[0036] Through the above steps, when the wake-up time sending conditions are met, the target functional module with the shortest remaining calling time is determined, and the time for instructing the hardware timer to wake up the target module is determined based on the time when the target functional module is called next time, so that the target module can be awakened only when there is a function that needs to be executed. This solves the problem that the energy consumption reduction method in the related art needs to determine the greatest common divisor of the execution cycles of multiple functional modules and instruct the timer to wake up the module every greatest common divisor. Therefore, when the greatest common divisor is small, the timer frequently wakes up the module, resulting in poor energy consumption reduction effect.

[0037] The execution subject of the above steps may be a camera device, other devices or systems that can carry modules and hard timers, etc., but is not limited thereto.

[0038] In an optional embodiment, after determining the target wake-up time based on the moment when the target functional module is called next time, the method further includes: determining the length of time between the target wake-up time and the current moment; determining the priority of the target functional module when the length of time between the target wake-up time and the current moment meets a predetermined condition; and executing the operation of calling the target functional module based on the priority of the target functional module.

[0039] In an optional embodiment, when the duration between the target wake-up time and the current moment meets a predetermined condition, determining the priority of the target functional module includes: when it is determined that the duration between the target wake-up time and the current moment is less than a first preset duration, determining the priority of the target functional module; executing the operation of calling the target functional module based on the priority of the target functional module includes: when the priority of the target functional module is the first priority, directly calling the target functional module to execute the target operation, wherein the functional module with the first priority is a module that allows adjustment of the function execution cycle.

[0040] In the above steps, the first preset duration includes but is not limited to: 5 minutes, 10 minutes, 20 minutes, etc. The first preset duration can be adjusted according to the different functions of the functional modules and the different application scenarios of the camera equipment where the functional modules are located.

[0041] Through the above steps, since the time length from the scheduled execution time to the current time is less than the first scheduled time length (i.e., the above-mentioned first preset time length) and the target functional module is a functional module that allows adjustment of the execution cycle, the functional module can be called first, thereby realizing the alignment operation of the calling time of multiple functional modules, reducing the number of times the target module is awakened, and reducing the energy consumption of the device.

[0042] For example, Figure 4 This is the process of the module wake-up method according to an embodiment of the present invention. Figure 2 ,like Figure 4 As shown, the process includes the following steps:

[0043] In step S402, the target module calculates a first time for sending to the hard timer to instruct the hard timer to wake up the target module next time to call a target function (i.e., the target function module). The target function is the function whose next execution time is shortest from the current calculation time among all functions.

[0044] Step S404: the target module determines whether the first time is less than a first predetermined time. If the first time is less than the first predetermined time, step S404 is executed.

[0045] Step S406: The target module determines whether the priority of the target function is PL (i.e., the first priority mentioned above). If the priority of the target function is PL, step S408 is executed.

[0046] Step S408: The target module calls the target function.

[0047] In the above steps, optionally, when the priority of the target function is PH (i.e., the second priority mentioned above), determine whether there are other functions whose scheduled execution time is less than the first scheduled time from the current time and whose priority is PL length. If there are other functions that meet the above conditions, execute the other functions that meet the above conditions.

[0048] In an optional embodiment, the target wake-up time is sent to the hardware timer to instruct the hardware timer to wake up the target module when the target wake-up time arrives, including: when the priority of the target functional module is the second priority, the target wake-up time is sent to the hardware timer to instruct the hardware timer to wake up the target module when the target wake-up time arrives, wherein the functional module with the second priority is a module that is not allowed to adjust the function execution cycle.

[0049] In an optional embodiment, the method further includes: obtaining attribute information of multiple functional modules; judging whether to allow adjustment of the function execution cycle of each functional module based on the attribute information of each functional module, and obtaining a judgment result; and setting the priority of each functional module based on the judgment result.

[0050] In the above steps, the attribute information includes but is not limited to: system modules, functional modules. For example, for system modules, it is set as a module whose execution cycle is not adjusted, and for functional modules, it is set as a module whose execution cycle can be adjusted. For example, modules with the first priority include but are not limited to: operating system modules, etc., and modules with the first priority include but are not limited to: sensor modules, lens modules, image processing modules, memory modules, display modules, interface modules, communication modules, power modules, auxiliary function modules, etc.

[0051] In an optional embodiment, determining the remaining call time of each of the functional modules includes: determining the remaining call time of each of the functional modules based on the execution cycle of each of the registered functional modules recorded in the target module, and the historical timestamp of each of the functional modules, wherein, if the functional module has been called before, the historical timestamp indicates the moment when the functional module was last called, and if the functional module has not been called before, the historical timestamp indicates the registration moment of the functional module.

[0052] In an optional embodiment, the wake-up time delivery condition includes at least one of the following: the target module completes calling any one of the multiple functional modules; any one of the multiple functional modules successfully registers with the target module.

[0053] In the above steps, the functional modules include but are not limited to: sensor module, lens module, image processing module, memory module, display module, operating system module, interface module, communication module, power module, auxiliary function module (for example, audio recording module, autofocus module, timer shooting module, scene mode module, etc.), etc. Exemplarily, when the image processing module completes video processing, the target module sends the time for waking up the target module next time to the hard timer. When the image processing module completes video processing, the target module sends the time for waking up the target module next time to the hard timer. When the target module successfully registers with the target module, the target module sends the time for waking up the target module next time to the hard timer.

[0054] In an optional embodiment, the method further includes: when a timestamp synchronization condition is met, calling a plurality of the functional modules to update the historical timestamp of each functional module to the current moment.

[0055] In an optional embodiment, the timestamp synchronization condition includes at least one of the following: the time between the current moment and the moment when any functional module included in the multiple functional modules is first called reaches a second preset time; a timestamp synchronization instruction is received.

[0056] In the above steps, the second preset time length includes but is not limited to: 5 minutes, 20 minutes, 1 hour, 5 hours, 10 hours, 20 hours, etc. The second preset time length can be adjusted according to the different functions of the functional modules and the different application scenarios of the camera equipment where the functional modules are located.

[0057] In an optional embodiment, illustratively, when the last execution time of all the functional modules (for functional modules that have not been executed, the registration time) is more than 1 hour from the current time, multiple functional modules are called to update the historical timestamp of each functional module to the current time. The target module receives the timestamp synchronization instruction in a manner including but not limited to: receiving via a wireless connection (e.g., Wi-Fi, Bluetooth, etc.), receiving via infrared, receiving via voice, receiving via a cloud platform installed on a camera device, etc.

[0058] For example, Figure 5 This is the process of the module wake-up method according to an embodiment of the present invention. Figure 3 ,like Figure 5 As shown, the process includes the following steps:

[0059] Step S502 , the target module determines the shortest operating cycle among the operating cycles of multiple functions (i.e., the aforementioned functional modules);

[0060] Step S504: the target module records the most recent running time of each of the multiple functions;

[0061] Step S506: the target module records the time differences between adjacent running times among the multiple most recent running times corresponding to the multiple functions, and calculates the average of the time differences of a predetermined number of consecutive adjacent running times;

[0062] Step S508: The target module determines whether the ratio of the average value to the shortest operation period is less than a threshold. If yes, step S510 is executed.

[0063] In step S510 , the target module resets time 0, runs all functions, and re-determines the time for instructing the hard timer to wake up the target module next time.

[0064] Through the above steps, since the ratio of the average time difference between adjacent running moments to the shortest running cycle is less than the threshold, the running moments are aligned by running all functions, thereby avoiding the target module from being frequently woken up in a short period of time, reducing the number of times the target module is woken up, and reducing the energy consumption of the device.

[0065] The following describes the module wake-up method of the present invention in combination with a specific embodiment, taking the module including two functions, function A and function B, as an example. Figure 6 This is the process of the module wake-up method according to an embodiment of the present invention. Figure 4 ,like Figure 6 As shown, the process includes the following steps:

[0066] Step S602: Function A sends a registration request to the target platform, and registers the execution period T1 corresponding to Function A, the timestamp t1 when Function A sends the registration request, and the callback function corresponding to Function A with the module;

[0067] Step S604, determining whether function A is successfully registered on the target platform, if yes, executing step S608, if not, executing step S606;

[0068] In step S606, the module (i.e., the aforementioned target module) instructs the hard timer to wake up the module at a time T1 from the current time. The module calls function A to send a registration request to the target platform again. If the registration is successful, the registration success time is updated to t1.

[0069] Step S608: Function B sends a registration request to the target platform, and registers the execution period T2 corresponding to Function B, the timestamp t2 when Function B sends the registration request, and the callback function corresponding to Function B with the module;

[0070] Step S610, determining whether function B is successfully registered on the target platform, if yes, executing step S614, if not, executing step S612;

[0071] Step S612: The module instructs the hard timer to wake up the module at a time T2 from the current time, invokes function B to send a registration request to the target platform again, and updates the registration success time to t2 if the registration is successful.

[0072] In step S614, the module determines the execution time corresponding to function A based on T1 and t1, and determines the execution time corresponding to function B based on T2 and t2;

[0073] In step S616 , the module calculates the function execution time closest to the current time, and instructs the hard timer to wake up the module at the most recent execution time.

[0074] In the above steps, when the module includes multiple functions, if the previous function is successfully registered, the next function is registered. Exemplarily, when the multiple functions include function A, function B, function C, and function D, if function A is successfully registered, function B is registered. Exemplarily, when the module includes multiple functions, if the multiple functions are successfully registered in sequence, the module calculates the function execution time closest to the current time and instructs the hard timer to wake up the module at the most recent execution time. Exemplarily, the method of determining that the function registration is successful includes but is not limited to: determining that the function registration is successful when a response message returned by the target platform is received.

[0075] In step S616, the module includes but is not limited to calculating the function execution time closest to the current time by: after the function B is successfully registered, the hard timer is turned off, and the time interval t from the next timer wake-up module to the time when timing is started again is calculated by the following formula, where the value of T is the time when the function B is successfully registered.

[0076] t=Min(((t1+T1)-T),((t2+T2)-T));

[0077] After calculating t, t1 and t2 are updated to the time when timing starts again.

[0078] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method.
