when the idle time length meets the sleep condition, acquiring data of each functional interface;
and if the user task is determined to be in the idle state based on the data, controlling the intelligent door lock system to enter a dormant state.
Referring to fig. 2, fig. 2 is a flowchart of a first embodiment of a method for reducing power consumption of an intelligent door lock according to the present application.
Embodiments of the present application provide embodiments of a method of reducing power consumption of a smart door lock, it being noted that although a logic sequence is shown in the flow chart, in some cases the steps shown or described may be performed in a different order than that shown or described herein.
The method for reducing the power consumption of the intelligent door lock comprises the following steps:
step S10, when the intelligent door lock system is detected to enter an idle state, acquiring the current idle time length;
the application environment of the method provided by the embodiment is that the method is applied to an intelligent door lock, the hardware of the intelligent door lock adopts an LPC55S6x series chip as a main control, and software adopts an RTOS system, wherein a Real-time operating system (Real-time operating system, RTOS) is also called an instant operating system.
After the intelligent door lock is electrified and initialized, executing a current user task, and when a user has no interaction with the intelligent door lock for a long time, enabling the RTOS system to enter an idle state (namely a standby state); at this time, the RTOS system executes an idle task, and in executing the idle task, the period Ti for which the system is idle and is expected to be maintained, that is, the idle period is first read by the RTOS system interface.
Step S20, when the idle time length meets the dormancy condition, acquiring data of each functional interface;
in order to avoid frequent dormancy and awakening of the RTOS system in a short time, a user is preset with the shortest dormancy time, namely a first preset dormancy time length, and the time length is generally set to be a few seconds, such as 5 seconds; meanwhile, the device can be set according to the actual demands of users, and is not limited herein. Comparing the first preset dormancy time length with the time Ti of the expected idle maintenance, and if the first preset dormancy time length is longer than the time Ti of the expected idle maintenance, keeping the RTOS system in an activated state continuously; if the first preset dormancy time is smaller than the preset dormancy time Ti, the condition of the first preset dormancy time is met, whether each user task is in an idle state is further judged, wherein the user task comprises a daily task, a burst task, a monitoring task, analysis and the like, and different user tasks can be generated based on different requirements of users. When the first preset dormancy time is smaller than the idle expected maintenance time Ti, the intelligent door lock initiates a collection request of the data of each function interface to the task scheduling module; after receiving the acquisition request, the task scheduling module stores the corresponding request data into a database, and builds a task acquisition table corresponding to the task; meanwhile, a task starting command comprising task starting parameters required by the task acquisition module is generated according to the task related data and is sent to the task acquisition module, and the task acquisition module performs corresponding acquisition work of the function data according to the starting parameters so as to acquire the data of the function interfaces. Wherein the request data includes: task name, data type, number of task concurrency, extraction mode, extraction frequency, etc.
And step S30, if the user task is determined to be in an idle state based on the data, controlling the intelligent door lock system to enter a dormant state.
When the intelligent door lock acquires the data of each functional interface fed back by the task acquisition module, the data is analyzed to determine whether each user task is in an idle state currently. Specifically, a task execution table corresponding to the data is obtained, whether user tasks waiting for execution exist in the task execution table is judged, if not, whether the executing user is executed completely is judged, and if all the executing user tasks are executed completely, the current user tasks are in an idle state. At this time, after the intelligent door lock performs the relevant low power consumption configuration, the control system enters a low power consumption sleep state. When the system enters a dormant state, all external modules, a CPU, a timer, a serial port and the like stop working, and only external interruption continues to work. Meanwhile, an instruction for enabling the system to enter the sleep state is the last instruction executed by the system before the sleep state, after entering the sleep state, data in a data memory and a special function register which are not related to a program in the MCU are kept at original values, and the system can be triggered by an external interrupt low level or by a falling edge or a hardware reset mode. When the interrupt wake-up single system is used, the program continues to run from the original stop, and when the hardware reset wake-up system is used, the program is executed from the beginning.
Further, referring to fig. 4, the step of controlling the intelligent door lock system to enter a sleep state includes:
step S31, carrying out low-power-consumption configuration on each external module; and
step S32, the wake-up duration is set, and the main control chip is controlled to enter a dormant state.
The low power consumption is a very important index of the MCU, such as some wearable devices, the electric quantity carried by the wearable devices is limited, and if the electric quantity consumed by the whole circuit is particularly large, the situation of insufficient electric quantity often occurs, so that the user experience is affected. Therefore, when the RTOS system goes to sleep, low power consumption configuration is required for each external module and the master MCU. For example: and the external module is configured to enter a low-power consumption mode, the upper peripheral and the clock which are irrelevant to low power consumption are closed, and the proper pin level is configured to avoid electric leakage. Meanwhile, the level state of the I/O port is required to be matched, a pull-up resistor is arranged in or outside the general I/O port, and if the level state of each I/O port is not set when the MCU enters the dormant state, a part of electric quantity is consumed. For example: if a certain I/O port has a 10kΩ pull-up resistor, the pin is pulled to 4V, and when the MCU goes into sleep, the I/O port is set to output a low level, and according to ohm's law, the pin consumes 4V/10k=0.4ma of current, which would cause power consumption if there were a plurality of such I/O ports. Therefore, before the MCU enters a dormant state, detecting the states of the I/O ports one by one, and if the I/O ports are provided with pull-up resistors, setting the I/O ports as high-level output or high-resistance input; if the I/O port is provided with a pull-down resistor, the pull-down resistor is set to be a low-level output or a high-resistance input.
After the low power consumption mode is successfully set, the program needs to be run periodically, then the low power consumption mode is entered, and after a certain time interval, the program continues to be run. At this time, the RTC clock is required to wake up the low power mode, and a periodic wake-up function is set, for example, the RTC alarm clock wakes up the low power mode automatically once every 50 s. Meanwhile, RTC/GINT interrupt needs to be set, GINT initializes more than 2 pins to the same group of interrupt, when no polarity effective signal exists in the same group, any one pin generates a polarity effective signal, and then the interrupt is generated. After the matching of each external module, the I/O port, the RTC wake-up, the GINT interrupt and the like is completed, the main control MCU enters a dormant state.
Further, referring to fig. 5, the step of setting the wake-up duration includes:
step S320, a second preset dormancy time length is obtained, and the second preset dormancy time length is compared with the idle time length;
step S321, if the second preset sleep time length is less than the idle time length, determining that the second preset sleep time length is the wake-up time length; or alternatively
Step S322, if the second preset sleep time period is longer than the idle time period, determining that the idle time period is the wake-up time period.
The maximum sleep time length, namely the second preset sleep time length, is preset in the intelligent door lock, and can be set to be a few minutes, a few hours or a few days, and the wake-up time length needs to be determined based on the maximum sleep time length before the MCU enters the sleep state. Specifically, comparing the time Ti of the idle predicted maintenance with the maximum dormancy time, and if the time Ti of the idle predicted maintenance is smaller than the maximum dormancy time, taking the time Ti of the idle predicted maintenance as the wakeup time; if the idle expected maintenance time Ti is greater than the maximum dormancy time, the maximum dormancy time is taken as the awakening time.
When the intelligent door lock system is detected to enter an idle state, the current idle time is acquired; when the idle time length meets the sleep condition, acquiring data of each functional interface; and if the user task is determined to be in the idle state based on the data, controlling the intelligent door lock system to enter the dormant state. Through carrying out the low-power consumption setting to each external module when intelligent lock system and each user task are in idle state to and set up wake-up time and make master control MCU get into sleep state, solved because intelligent lock functional module is more, lead to the consumption of intelligent lock higher, need frequently change the problem of battery, effectively reduced the consumption of intelligent electric lock, reduced the change number of times of battery and improved intelligent lock's life-span.
Further, referring to fig. 3, a second embodiment of the method for reducing power consumption of the intelligent door lock is provided.
The second embodiment of the method for reducing power consumption of the intelligent door lock is different from the first embodiment of the method for reducing power consumption of the intelligent door lock in that after the step of controlling the intelligent door lock system to enter the sleep state, the method further includes:
step S33, when the current sleep time length reaches the wake-up time length, automatically waking up the intelligent door lock system;
step S34, obtaining a current first idle duration, and if the first idle duration meets the sleep condition and the user task is in an idle state, controlling the intelligent door lock system to enter the sleep state again.
The intelligent door lock has two awakened conditions, one is to achieve automatic awakening of the sleep time, and the other is to receive an awakening signal to awaken. When the sleep time of the intelligent door lock reaches the wake-up time and the wake-up signal is not received, the intelligent door lock is awakened by an internal RTC; after awakening, the system resumes scheduling, and if no event needs to be processed (user task is idle), the system invokes an idle task, and can sleep again in the idle task. That is, in case that the RTOS system is detected to be idle and all user tasks are idle, it is determined that the sleep condition is satisfied, and the MCU enters the sleep state again. For example: the wake-up time is 1 hour, the intelligent door lock does not receive a wake-up signal within 1 hour, automatic wake-up is carried out, data of each functional interface is detected after wake-up, when it is determined that each current user task is in an idle state, the current sleep condition is met, the RTOS system is controlled to enter the sleep state again, and the next periodic wake-up is waited.
Further, referring to fig. 6, after the step of controlling the intelligent door lock system to enter the sleep state, the method further includes:
step S35, when a wake-up signal is received, the main control chip is waken up; and
when the intelligent door lock receives a wake-up signal, namely after an external event occurs or the RTC wakes up, the main control MCU wakes up from a power-down mode, wherein the sleep mode of the intelligent door lock generally comprises: sleep mode, deep sleep mode, power down mode, and deep power down mode, and for each mode selection, two metrics are included: the sleep current is low and the wake-up speed is fast.
Further, referring to fig. 7, the step of waking up the main control chip when receiving the wake-up signal includes:
step S350, when the target key is detected to be in a pressed state, a high-level signal is generated;
and S351, waking up the main control chip according to the high-level signal.
In the intelligent door lock, a key module is in communication connection with a main control MCU through an SPI port, and a plurality of target keys are preset by a user and are used for waking up a system. Meanwhile, the target key is connected with the main control MCU, and when the target key is pressed, a high-level signal is generated to wake up the main control MCU, wherein the high-level signal can be triggered by manual operation or autonomous intelligent triggering. Optionally, the target key may also be a virtual key, for example: when a user presses a target virtual key on the mobile phone, a high-level signal is generated, and the mobile phone sends the high-level signal to the intelligent door lock so as to wake up the main control MCU.
Optionally, the wake-up operation of the master control MCU may also be performed through voice information sent by the user, for example: the user presets a wake-up word of small T and small T, and the wake-up word is stored in the intelligent door lock. When a user sends a small T and a small T to the intelligent door lock, the intelligent door lock automatically recognizes the voice information to acquire text content in the voice information, and if the text content is consistent with a prestored awakening word, the main control MCU is awakened.
And S36, performing wake-up configuration on the external modules, and correcting the beat of the intelligent door lock system.
After the main control MCU is awakened, the external modules are further subjected to awakening configuration, the system beat of the intelligent door lock is corrected, specifically, after the main control MCU is awakened, the working mode of each external module is set to be an operation mode, meanwhile, the power supply, related pins, clocks and the like of each external module are set, and when the clocks are set, clock parameters such as opening of an external high-speed clock crystal oscillator, setting of a system clock and the like are required to be set. Secondly, when the intelligent door lock is in sleep, a system clock (system beat) is stopped, so that the system beat is stopped in the sleep period, and after the intelligent door lock is awakened, the system beat is added with the system beat number corresponding to the sleep time. Where all operating systems need to provide a system clock beat for the system to handle time-dependent events (timebases), such as delays, timeouts, etc. The system clock beats are specific periodic interrupts, the clock intervals between the interrupts depend on different applications, the time base is set, and the time base is generally about 1ms, meanwhile, the clock beats interrupt enables tasks to be delayed by a plurality of clock beats (the CPU is released to other tasks and then executed after a plurality of times); when a task wait event occurs, a wait timeout wait is also provided, and the faster the clock beat frequency, the greater the system overhead. Therefore, after the intelligent door lock is awakened, the system beat needs to be corrected in time so as to avoid high system cost caused by too fast system beat frequency.
Further, referring to fig. 8, after the step of performing wake-up configuration on the external modules and correcting the beat of the intelligent door lock system, the method further includes:
step S360, a scheduling instruction is obtained, wherein the scheduling instruction is used for indicating the user task to be executed;
step S361, starting the intelligent door lock system to process the user task according to the scheduling instruction.
After receiving the wake-up signal, the intelligent door lock automatically generates a scheduling instruction or receives the scheduling instruction issued by a dispatcher from the client, wherein the scheduling instruction is used for indicating the user task to be executed, and the intelligent door lock system is started to process the user task according to the scheduling instruction. Specifically, the intelligent door lock divides the user task into three low levels in advance, such as: the first level (emergency), the second level (important) and the third level (common) further adopt different scheduling methods for user tasks with different priorities according to the load condition of the system. For example: for a user task of a first level, firstly searching an idle working thread from a system, and scheduling the user task to the idle working thread for execution; if no idle worker thread is found, a new idle worker thread is created and the user task is scheduled to the newly created worker thread. For user tasks of a second level, firstly, obtaining expected waiting time of each user task in a waiting queue from a system, comparing the expected waiting time with the latest execution time of the current user task, obtaining a task queue with expected waiting time smaller than the latest execution time of the current user task, and dispatching the current user task to the tail end of the task queue; if the matched task queue is not found, searching an idle working thread in the system, and scheduling the current user task to the idle time thread. And for the user task of the first level, acquiring the content corresponding to the execution of the user task, searching a non-idle working thread matched with the content in the system, and scheduling the user task to the non-idle working thread. By dividing the user tasks into three different grades and adopting different scheduling schemes based on the different grades, the user tasks can be executed in time, and the requirement of the user on real-time performance is met.
In the embodiment, after an external event occurs or the RTC wakes up, the main control MCU wakes up from a power-down mode, wakes up each external module and corrects the system beat, and simultaneously, the system is started to process the user task in time through the scheduling instruction by acquiring the scheduling instruction, so that each transaction can be processed in time after the system is waken up, and the normal operation of the system is ensured.
In order to better explain the scheme of the embodiment of the application, the operation flow of the method for reducing the power consumption of the intelligent door lock in terms of software is as follows:
referring to fig. 9, after the smart door lock is powered on, the RTOS system enters an initialization, and after the initialization is completed, processes the current user task. When the user does not interact with the intelligent door lock for a long time (such as 2 hours), whether the RTOS system enters an idle state (namely a standby state) is detected, if so, an idle task is executed, and if not, the step of detecting whether the RTOS system enters the idle state is executed again. In the process of executing the idle task, acquiring the expected maintenance time Ti of the system idle, namely the idle time, judging whether the idle time meets the dormancy requirement, and if the expected maintenance time Ti of the system idle is larger than the shortest dormancy time, judging that the idle time meets the dormancy requirement; if the idle expected sustain time Ti is less than the minimum sleep time, the step of detecting whether the RTOS system enters an idle state is performed back. When the idle time meets the sleep requirement, acquiring data of each functional interface of the system, judging whether user tasks in the system are idle or not according to the data, and if so, performing low-power-consumption sleep configuration on an external module; if any non-idle user task exists, returning to execute the step of detecting whether the RTOS system enters an idle state. When the sleep configuration of the external module with low power consumption is carried out, the external module is required to be configured to enter a low power consumption mode, an upper peripheral and a clock which are irrelevant to the low power consumption are closed, proper pin levels are configured to avoid electric leakage and the like, the RTC wake-up and the GINT wake-up are further required to be configured, the idle predicted maintenance time Ti is compared with the maximum sleep time, and if the idle predicted maintenance time Ti is smaller than the maximum sleep time, the idle predicted maintenance time Ti is taken as the wake-up time; if the idle expected maintenance time Ti is greater than the maximum dormancy time, the maximum dormancy time is taken as the awakening time. After the configuration is completed, the main control MCU is controlled to enter a power-down mode, and meanwhile, RTC/GINT timing interruption is set. When a wake-up signal is received, the main control MCU is waken up, wake-up configuration is carried out on each external module, the beat of the intelligent door lock system is corrected, a scheduling instruction is obtained at the same time, and the intelligent door lock system is started to process the user task according to the scheduling instruction. After the system is awakened to work normally, the real-time detection is continued to be carried out whether the RTOS system enters an idle state (namely a standby state).
