Those skilled in the art will appreciate that the intelligent door lock structure shown in fig. 1 does not constitute a limitation of the intelligent door lock apparatus, and may include more or less components than those shown, or combine some components, or arrange different components.
As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a network communication module, a user interface module, and a program for reducing power consumption of the smart door lock.
In the intelligent door lock shown in fig. 1, the network interface 1004 is mainly used for connecting to a background server and performing data communication with the background server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call the program for reducing the power consumption of the smart door lock in the memory 1005, and perform the following operations:
when the intelligent door lock system is detected to enter an idle state, acquiring the current idle time;
when the idle time meets the dormancy 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 schematic flowchart of a first embodiment of the method for reducing power consumption of an intelligent door lock according to the present application.
While a logical order 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 detecting that the intelligent door lock system enters an idle state, acquiring the current idle time length;
the application environment of the method provided by this embodiment is to be applied to an intelligent door lock, the hardware of the intelligent door lock adopts LPC55S6x series chip as a main control, and the software adopts an RTOS system, wherein, a Real-time operating system (RTOS), also called as an instant operating system, is characterized by Real-time performance, if a task needs to be executed, the Real-time operating system can execute the task in a shorter time without a longer delay compared with a general operating system.
After the intelligent door lock is powered on and initialized, executing a current user task, and when a user does not interact with the intelligent door lock for a long time, entering an idle state (namely a standby state) by the RTOS system; at this time, the RTOS system executes an idle task, in which the time Ti, i.e., the idle duration, for which the system is expected to be idle is read by the RTOS system interface.
Step S20, when the idle time length meets the dormancy condition, acquiring the data of each functional interface;
in order to avoid frequent dormancy and awakening of the RTOS system in a short time, a user presets a shortest dormancy time, namely a first preset dormancy duration, which is generally set to be only several seconds, such as 5 seconds; meanwhile, the setting can be set according to the actual requirements of the user, and is not limited herein. Comparing the first preset dormancy duration with the idle expected maintenance time Ti, and if the first preset dormancy duration is greater than the idle expected maintenance time Ti, keeping the RTOS system in an activated state continuously; if the first preset dormancy duration is less than the time Ti of the expected idle maintenance, the condition of the first preset dormancy duration is met, whether each user task is in an idle state is further judged, wherein the user tasks comprise daily tasks, burst tasks, monitoring tasks, analysis and the like, and different user tasks can be generated based on different user requirements. When the first preset dormancy duration is less than the idle expected maintenance time Ti, the intelligent door lock initiates a collection request of data of each functional interface to the task scheduling module; after receiving the acquisition request, the task scheduling module stores the corresponding request data into a database and creates a task acquisition table corresponding to the task; and 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 each function data according to the starting parameters so as to acquire the data of each function interface. Wherein the request data comprises: task name, data type, task concurrency, extraction mode, extraction frequency and the like.
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 sleep 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 current user task is in an idle state. Specifically, a task execution table corresponding to the data is obtained, whether user tasks waiting to be executed exist in the task execution table is judged, if not, whether the executing users finish executing is judged, and if all the user tasks are finished, all the user tasks are in an idle state. At this moment, after the intelligent door lock is configured with relevant low power consumption, the control system enters a low power consumption dormant state. When the system enters a dormant state, all the external modules, the CPU, the timer, the serial port and the like stop working, and only external interruption continues working. Meanwhile, the instruction for making the system enter the dormant state becomes the last instruction executed by the system before the dormancy, and after the system enters the dormant state, the data in the data memory and the special function register which are not related to the program in the MCU keep the original values, and the system can be triggered by external interrupt low level or triggered by falling edge to interrupt or be awakened in a hardware reset mode. It should be noted that, when the single system is woken up by using the interrupt, the program continues to run from the original stop, and when the system is woken up by using the hardware reset, the program will be executed from the beginning.
Further, referring to fig. 4, the step of controlling the intelligent door lock system to enter the sleep state includes:
step S31, configuring each external module with low power consumption; and
and step S32, setting the awakening time length and controlling the main control chip to enter a dormant state.
The low power consumption is a very important index of the MCU, for example, some wearable devices have limited power consumption, and if the power consumed by the whole circuit is very large, the power is often insufficient, which affects the user experience. Therefore, when the RTOS system goes to sleep, low power consumption configuration needs to be performed on each external module and the master MCU. For example: and configuring an external module to enter a low power consumption mode, closing off the upper peripheral and the clock irrelevant to low power consumption, and configuring a proper pin level to avoid electric leakage. Meanwhile, the level state of the I/O port needs to be configured, a pull-up resistor and a pull-down resistor are arranged inside 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 sleep state, a part of electric power is consumed. For example: if a certain I/O port has a pull-up resistor of 10K Ω, the pin is pulled to 4V, and when the MCU enters a sleep state, the I/O port is set to output a low level, and according to ohm's law, the pin consumes a current of 0.4mA to 4V/10K. Therefore, before the MCU enters the sleep state, the states of the I/O ports are detected one by one, and if the I/O ports are provided with pull-up resistors, high-level output or high-resistance input is set; if the I/O port is provided with a pull-down resistor, the I/O port 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 periodically operated, then the low power consumption mode is entered, and after a certain time interval, the program is continuously operated. At this time, the RTC clock is needed to wake up the low power consumption mode, and a periodic wake-up function is set, for example, the RTC alarm clock automatically wakes up once every 50 s. Meanwhile, an RTC/GINT interrupt is also needed to be set, more than 2 pins are initialized by the GINT to be the same group of interrupts, and when any polarity valid signal does not exist in the same group, any one pin generates a polarity valid signal and then generates the interrupts. And after matching of each external module, the I/O port, RTC awakening, GINT interruption 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, acquiring a second preset sleep time, and comparing the second preset sleep time with the idle time;
step S321, if the second preset sleeping duration is less than the idle duration, determining that the second preset sleeping duration is the wakeup duration; or
Step S322, if the second preset sleeping duration is greater than the idle duration, determining that the idle duration is the wakeup duration.
The intelligent door lock is preset with a maximum sleeping time, namely a second preset sleeping time, the maximum sleeping time can be set to be several minutes, hours or days, and before the MCU enters a sleeping state, the awakening time needs to be determined based on the maximum sleeping time. Specifically, the time Ti of the estimated idle maintenance is compared with the maximum dormancy duration, and if the time Ti of the estimated idle maintenance is less than the maximum dormancy duration, the time Ti of the estimated idle maintenance is taken as the awakening duration; and if the time Ti of the expected idle maintenance is larger than the maximum dormancy duration, taking the maximum dormancy duration as the awakening duration.
The method comprises the steps of acquiring the current idle time when detecting that an intelligent door lock system enters an idle state; when the idle time meets the dormancy 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 when intelligent lock system and each user task all are in idle state, carry out the low-power consumption setting to each outside module to and set up awakening time and make master control MCU get into the dormancy state, solved because intelligent lock functional module is more, the consumption that leads to intelligent lock is higher, need frequently change the problem of battery, effectively reduced the consumption of intelligent electric lock, reduce the change number of times of battery and improved the life-span of intelligent lock.
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 the power consumption of the intelligent door lock is different from the first embodiment of the method for reducing the 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 comprises the following steps:
step S33, when the current dormancy duration reaches the awakening duration, automatically awakening the intelligent door lock system;
step S34, acquiring a current first idle time, and if the first idle time 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 awakening conditions, one is to automatically awaken when the sleep time is reached, and the other is to receive an awakening signal to awaken. When the sleep duration of the intelligent door lock reaches the awakening time and the awakening signal is not received, the intelligent door lock is awakened by the internal RTC; and after waking up, the system resumes scheduling, and if no event needs to be processed (the user task is idle) at present, the system calls an idle task and can sleep again in the idle task. That is, in the case where it is detected that the RTOS system is 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: and when the awakening time is 1 hour, the intelligent door lock does not receive the awakening signal within 1 hour, automatically awakening, detecting data of each functional interface after awakening, judging that the current sleep condition is met when determining that each current user task is in an idle state, controlling the RTOS system to enter the sleep state again, and waiting for the next periodic awakening.
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 receiving the wake-up signal, waking up the main control chip; and
when the intelligence lock received wake-up signal, external event takes place or RTC awakens up the back promptly, and main control MCU will follow the power down mode and awaken up, and wherein, the sleep mode of intelligence lock generally includes: sleep mode, deep sleep mode, power down mode, and deep power down mode, and for the selection of each mode, two indicators are included: low sleep current and fast wake-up speed.
Further, referring to fig. 7, when receiving the wake-up signal, the step of waking up the main control chip includes:
step S350, generating a high-level signal when detecting that the target key is in a pressed state;
and step S351, awakening the main control chip according to the high-level signal.
In the intelligent door lock, the key module is in communication connection with the main control MCU through the SPI, a user is provided with a plurality of target keys in advance, and the target keys are used for awakening the system. Meanwhile, the target key is connected with the main control MCU, and after the target key is pressed, a high level signal can be 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 that the main control MCU is awakened.
Optionally, the main control MCU may also be awakened through voice information sent by a user, for example: the user presets a wake-up word '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 identifies the voice information, obtains text contents in the voice information, and wakes up the main control MCU if the text contents are consistent with the pre-stored wake-up words.
And step S36, performing awakening configuration on each external module, and correcting the beat of the intelligent door lock system.
After waking up the main control MCU, further waking up and configuring each external module, and correcting the system clock of the intelligent door lock, specifically, after waking up the main control MCU, setting the working mode of each external module as the running mode, and simultaneously, setting the power supply, the related pins, the clock, etc. of each external module, when setting the clock, setting the clock parameters, such as turning on the external high-speed clock crystal oscillator, setting the system clock, etc. Secondly, when the intelligent door lock is in a sleep state, a system clock (system beat) is stopped, so that the system beat is stopped in the sleep time, and after the intelligent door lock is awakened, the system beat is added with the system beat number corresponding to the sleep time. All operating systems need to provide a system clock beat for the system to process time-related events (timebases) such as delays, timeouts, etc. The system clock beat is a specific periodic interruption, the clock interval between the interruptions depends on different applications, a time base is set, generally about 1ms, and meanwhile, the clock beat interruption of the clock can delay the task by a plurality of clock beats (the CPU is released to other tasks and the task is executed after a plurality of time); wait timeout waiting is also provided when a task wait event occurs, 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 the problem that the system beat frequency is too high, which causes high system overhead.
Further, referring to fig. 8, after the step of performing wakeup configuration on each external module and correcting the beat of the intelligent door lock system, the method further includes:
step S360, obtaining a scheduling instruction, wherein the scheduling instruction is used for indicating the user task to be executed;
and step S361, starting the intelligent door lock system to process the user task according to the scheduling instruction.
And after receiving the awakening 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 pre-classifies user tasks into three low levels, such as: the first level (emergency), the second level (important) and the third level (normal) adopt different scheduling methods for user tasks with different priorities further 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; and if the idle working thread is not found, creating a new idle working thread, and scheduling the user task to the newly created working thread. For the user tasks of the second level, the expected waiting time of each user task in the waiting queue is obtained from the system, the expected waiting time is compared with the latest execution time of the current user task, a task queue with the expected waiting time being less than the latest execution time of the current user task is obtained, and the current user task is dispatched to the tail end of the task queue; and if the matched task queue is not found, searching an idle working thread in the system, and scheduling the current user task to an idle time thread. And for the user task of the first level, acquiring the content correspondingly executed by 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. The user tasks are divided into three different grades, and different scheduling schemes are adopted based on different grades, so that the user tasks can be executed in time, and the real-time requirements of users are met.
In this embodiment, after an external event occurs or an RTC wakes up, the main control MCU wakes up from the power down mode to wake up configuration and modify system beats for each external module, and meanwhile, by acquiring a scheduling instruction, the system is started in time to process the user task through the scheduling instruction, so that the system can process various transactions in time after being woken up, and normal operation of the system is ensured.
To better explain the scheme of the embodiment of the present 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 initialization, and after the initialization is completed, the current user task is processed. When a 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 yes, an idle task is executed, and if not, the step of detecting whether the RTOS system enters the idle state is returned. In the process of executing the idle task, acquiring the time Ti of the system for the estimated idle maintenance, namely the idle time, judging whether the idle time meets the sleep requirement, and if the time Ti of the estimated idle maintenance is greater than the shortest sleep time, judging that the idle time meets the sleep requirement; and if the time Ti of the expected idle maintenance is less than the shortest sleep time, returning to the step of detecting whether the RTOS system enters the idle state or not. 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 through the data, and if so, performing low-power-consumption sleep configuration on an external module; and if any non-idle user task exists, returning to the step of detecting whether the RTOS system enters an idle state or not. When the low-power-consumption sleep configuration of the external module 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 low power consumption are closed, a proper pin level is configured, electric leakage and the like are avoided, further RTC wakeup and GINT wakeup are required to be configured, the idle expected maintenance time Ti is compared with the maximum sleep duration, and if the idle expected maintenance time Ti is smaller than the maximum sleep duration, the idle expected maintenance time Ti is taken as the wakeup duration; and if the time Ti of the expected idle maintenance is larger than the maximum dormancy duration, taking the maximum dormancy duration as the awakening duration. And after the configuration is finished, controlling the main control MCU to enter a power-down mode, and setting RTC/GINT timing interruption at the same time. When receiving the awakening signal, awakening the main control MCU, awakening and configuring each external module, correcting the beat of the intelligent door lock system, simultaneously acquiring a scheduling instruction, and starting the intelligent door lock system to process the user task according to the scheduling instruction. And after the system is awakened to work normally, continuously detecting whether the RTOS system enters an idle state (namely a standby state) in real time.
This embodiment all is in when idle state at intelligent lock system and each user task, carries out the low-power consumption setting to each external module to and set up awakening time and make master control MCU get into the dormancy state, solved because intelligent lock functional module is more, the consumption that leads to intelligent lock is higher, need frequently change the problem of battery, effectively reduced the consumption of intelligent electric lock, reduce the change number of times of battery and improved the life-span of intelligent lock.
In addition, this application still provides a system for reducing power consumption of intelligent door lock, and in an embodiment, the system includes a memory, a processor, and a program for reducing power consumption of intelligent door lock that is stored on the memory and can be run on the processor, and the program for reducing power consumption of intelligent door lock realizes the following steps when being executed by the processor:
when the intelligent door lock system is detected to enter an idle state, acquiring the current idle time;
when the idle time meets the dormancy condition, acquiring data of each functional interface;
