Description
Technical Field
The invention belongs to the technical field of products of the Internet of things, and particularly relates to an application response method, an application response system, a storage medium and a communication module.
Background
In order to reduce the product cost and exploit the computing potential of the communication module as much as possible, the Internet of things (IoT) product transfers the work of the MCU to the communication module through the OpenCPU technology and completes all tasks of the MCU in the form of APP, so that the Application program (APP) of the user runs in the communication module, and thus the MCU on the Internet of things product can be omitted, and the hardware cost of the Internet of things device can be reduced without reducing the function and performance.
The existing OpenCPU products load an App developed based on an OpenCPU API after an RTOS (Real Time Operating System) normally operates and a communication module completes System initialization and can normally work, and at this Time, the App software can start to operate, so that the Time for the App to start to operate is usually 2-3 seconds later than the Time for communication (depending on the System initialization Time). This approach is not problematic in common applications, but has significant drawbacks for scenarios where power consumption requirements are very stringent and real-time control requirements are high, such as NB-IoT products.
The communication module of the NB-IoT product supports a PSM state (power saving Mode), and in order to ensure that very low power consumption is achieved in this state, all on-chip devices including a memory except a Real-time clock (RTC) are turned off in the PSM state, and power supply and a clock of an RTC-related module are reserved so that the PSM can exit from the PSM state and enter a normal operating state when the RTC-related module needs to operate. Because the large-capacity memory is closed before the PSM state is entered and partial system data is lost, the system needs to be reinitialized after the PSM mode exits, the initialization process can be completed within almost 2-3 seconds, so that response of the App is delayed for 2-3 seconds due to system initialization, power consumption increased by the delay cannot be accepted in low-power-consumption IoT products, and the MCU cannot be directly removed on the low-power-consumption IoT products.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides an application program response method, a system, a storage medium and a communication module, aiming at the problem that the response of an App is delayed for a long time due to the system initialization work of a communication module of the existing low-power-consumption IoT product, so that the App cannot be operated in the communication module and the MCU cannot be directly removed, so that the App can be operated in the communication module by adopting the local control function of a preset program when a wakeup source other than the preset wakeup source is obtained, and the system initialization time after the communication module is awakened is greatly shortened, so that the App can be operated in the communication module, and the MCU can be removed in the hardware design.
Example one
Please refer to fig. 1, which is a flowchart illustrating an application response method according to an embodiment of the present invention, wherein the application response method is applied to a communication module, the communication module can implement the method through software and/or hardware, and the method specifically includes steps S01 to S03.
Step S01, when the communication module is woken up in the power saving mode, acquiring a wake-up source of the communication module.
It should be noted that the power saving mode is a low power consumption state of the PSM, and the communication module may turn off all on-chip devices including the mass storage except the RTC in the PSM state, and only reserve the power supply and the clock of the module related to the RTC, so that when the communication module needs to wake up to work, the communication module is controlled to exit the PSM state to enter a normal working state.
The wake-up source may be a trigger event for waking up the communication module, and the wake-up source is configured to wake up the communication module, so that the communication module exits the PSM state and enters the normal operating state. The wake-up source may specifically be an external interrupt wake-up, an RTC wake-up, an Alarm wake-up (Tracking Area Update) of TAU, or the like.
Step S02, determining whether the wake-up source is a preset wake-up source.
Wherein, the awakening source is a currently acquired awakening source, and when the awakening source is judged not to be a preset awakening source, the step S03 is executed; when the wake-up source is determined to be the preset wake-up source, step S04 is executed. Specifically, the preset wake-up source may be TAU Alarm wake-up, and generally, non-TAU Alarm wake-up indicates that the system has a real-time control task request (such as a key, system power down, timing data sampling, and the like), and at this time, a preset program in the execution communication module may be called to perform detection, processing, control, and the like required by the system, so as to respond to the operation of the application program. And the TAU Alarm awakens to indicate that the system has a request for updating the tracking area, and the latest condition of the area must be updated by networking through the communication function of the communication module.
In step S03, the local control function of the preset program is executed to locally respond to the application request.
The preset program may be a BootApp, and specifically, a Bootloader may be added to the communication module (if the communication module of the Bootloader already exists, the Bootloader does not need to be added), and the Bootloader calls and executes the BootApp to execute a local control function of the BootApp to perform detection, processing, control and other operations required by the system, so as to quickly respond to the request of the application program locally.
In specific implementation, the BootApp code may be stored in an independent storage space, the BootApp and the Bootloader share a stack space by using an SRAM space independent from the Bootloader, the BootApp may be compiled by a special SDK independent from the App, and the BootApp may be downloaded into the communication module by a special downloading tool, or may be downloaded into an independent BootApp partition by using a downloading tool the same as the App.
Step S04, initializing and starting the communication module, and responding to the application request after the communication module is initialized.
It should be noted that, after the communication module completes system initialization and can work normally, the communication function of the communication module is restarted, and the communication module is used to network update the region and respond to the request of the application program.
To sum up, in the application response method in this embodiment, when an awake source other than the preset awake source is acquired, the local control function of the preset program is adopted to locally respond to the application request, and because the preset program only uses the processor on the communication module and does not need to use the communication function when running, the system initialization time after the communication module is awakened is greatly shortened, the App response delay is shortened from 2-3 seconds to within 5 milliseconds, the requirements of controlling all low-power IoT systems can be basically met, so that the MCU can be completely removed from the hardware design of the low-power IoT product, and the hardware cost of the low-power IoT product is reduced.
Example two
Please refer to fig. 2, which is a flowchart illustrating an application response method according to a second embodiment of the present invention, wherein the application response method is applied to a communication module, the communication module can be implemented by software and/or hardware, and the method specifically includes steps S11 to S19.
Step S11, when the communication module is woken up in the power saving mode, acquiring a wake-up source of the communication module.
Step S12, determining whether the wake-up source is a preset wake-up source.
The awakening source is a currently acquired awakening source, and the preset awakening source is TAU Alarm awakening. And executing the step S13 to the step S18 when the wake-up source is judged not to be the preset wake-up source, and directly jumping to execute the step S19 when the wake-up source is judged to be the preset wake-up source. In specific implementation, a Bootloader may be added to the communication module (if the communication module of the Bootloader already exists, the Bootloader does not need to be added), and the Bootloader distinguishes different wake-up sources.
And step S13, turning off clocks and power supplies other than the preset clock and power supply, which are the clocks and power supplies required for the operation of the preset program.
It can be understood that by turning off the clocks and power supplies of all the unused devices and executing the preset program BootApp with the lowest system power consumption, the power consumption of the communication module can be effectively reduced, so that the communication module operates in an extremely low power consumption state.
Step S14, executing the local control function of the preset program to locally respond to the application program request.
The preset program may be a BootApp, and specifically, the BootApp may be executed by calling an entry function of the BootApp through a Bootloader, so as to perform operations such as detection, processing, and control required by the system.
Step S15, storing the execution data of the preset program in the file system of the communication module.
The execution data of the preset program can be contained in the execution return value of the preset program or extracted from the execution log of the preset program, and useful data produced in the BootApp execution are stored in the file system of the communication module for the App to access.
And step S16, judging whether the preset program completes all preset works.
When it is determined that the preset program completes all the preset tasks, step S17 is executed, and when it is determined that the preset program does not complete all the preset tasks, step S18 is executed.
In specific implementation, the step S16 may be specifically implemented according to the following refining steps, where the refining steps specifically include:
judging whether the execution return value of the preset program is a preset value or not; and when the execution return value is not the preset value, judging that the preset program does not finish all preset works.
The preset value can be 0, that is, after the BootApp finishes executing the requests of all the application programs, an execution state value of 0 is returned to the Bootloader to represent that the BootApp finishes executing all the work; otherwise, returning an execution state value which is not 0 to the Bootloader so as to represent that the BootApp executes the request of partial application program.
Step S17, controlling the communication module to enter the power saving mode.
Step S18, controlling the communication module to enter a WFI state, and waiting for the communication module to be woken up by interruption and then executing the preset program again.
Specifically, whether the PSM state or the WFI state is directly entered again is determined through the BootApp return value, if the PSM state is entered, all work is finished and waiting for the next task, if the PSM state is entered, all work is finished, and if the WFI state is entered, partial work is finished, and the communication module enters the low-power-consumption WFI state and waits for the communication module to be interrupted and woken up and then executes the BootApp again.
Step S19, initializing and starting the communication module, and responding to the application request after the communication module is initialized.
It should be noted that, after the communication module completes system initialization and can work normally, the communication function of the communication module is started, and the tracking area information is updated by the communication function of the communication module, and the request of the application program is responded.
In addition, it should be further noted that in this embodiment, all the steps may be executed by a Bootloader of the communication module, but the present invention is not limited thereto, and in other embodiments, the BootApp may be used to replace the Bootloader, so as to determine, in the BootApp, whether to start the communication module or execute a local control function of the BootApp according to the wakeup source.

and the application response module 13 is configured to, when it is determined that the wake-up source is not the preset wake-up source, execute a local control function of a preset program to locally respond to an application request.
It should be noted that the power saving mode is a low power consumption state of the PSM, and the communication module may turn off all on-chip devices including the mass storage except the RTC in the PSM state, and only reserve the power supply and the clock of the module related to the RTC, so that when the communication module needs to operate, the communication module is controlled to exit the PSM state to enter a normal operating state.
The wake-up source may be a trigger event for waking up the communication module, and the wake-up source is configured to wake up the communication module, so that the communication module exits the PSM state and enters the normal operating state. The wake-up source may specifically be an external interrupt wake-up, an RTC wake-up, a TAU (Tracking Area Update, Update Tracking Area alert wake-up, or the like.
Specifically, the preset wake-up source may be TAU Alarm wake-up, and generally, non-TAU Alarm wake-up indicates that the system has a real-time control request (such as a key, system power down, timing data sampling, and the like), and at this time, a preset program in the communication module may be called to perform detection, processing, control, and the like required by the system, so as to respond to the operation of the application program. And the TAU Alarm awakens to indicate that the system has a request for updating the tracking area, and the tracking area information must be updated through networking by means of the communication function of the communication module.
The preset program may be a BootApp, and specifically, a Bootloader may be added to the communication module (if the communication module of the Bootloader already exists, the Bootloader does not need to be added), and the Bootloader is invoked to execute the BootApp to execute a local control function of the BootApp to perform operations such as detection, processing, and control required by the system. In specific implementation, the BootApp code may be stored in an independent storage space, an SRAM and a Flash space independent of the Bootloader are used, the BootApp and the Bootloader share a stack space, the BootApp may be compiled by a special SDK independent of the App, and the BootApp may be downloaded to the communication module by a special downloading tool, or may be downloaded to an independent BootApp partition by using a same downloading tool as the App.
To sum up, in the application response system in this embodiment, when acquiring a wake-up source other than the preset wake-up source, the local control function of the preset program is used to locally respond to the application request, and because the preset program is run only using the processor on the communication module and does not need to use the communication function, the system initialization time after the communication module is woken up is greatly shortened, App response delay is shortened from 2-3 seconds to within 5 milliseconds, which basically can meet the control requirements of all low-power IoT systems, so that the MCU of the low-power IoT product can be completely removed in hardware design, and the hardware cost of the low-power IoT product is reduced.
