Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The power utilization control method of the intelligent gateway provided by the application can be applied to an application environment shown in figure 1. In the application environment, the intelligent gateway 102 can communicate with the intelligent terminal 104 through a network, the intelligent gateway 102 can be deployed in an outdoor environment, and electric energy is obtained by adopting a solar power supply and/or induction power supply mode, and the electric energy obtained by the intelligent gateway 102 can be used for the work of the intelligent gateway 102; alternatively, the intelligent gateway 102 may be electrically connected to the intelligent terminal 104, and the intelligent gateway 102 may distribute the acquired electric energy to the intelligent terminal 104.
The intelligent terminal 104 may be a monitoring device, which may monitor and collect data on the transmission line and/or the grid device. In an example, the intelligent terminal 104 may be one or more sensors with different service functions, such as a sensor for collecting image data, video data, tension data, temperature data, wire galloping data, etc., which may include at least one of the following: the intelligent spacer comprises camera equipment, a microclimate sensor, a tower inclination sensor, a tension sensor, an inclination sensor, a wire clamp temperature sensor, a wire galloping sensor and an intelligent spacer. The intelligent terminal 104 may also include at least one of a wired sensor and a wireless sensor.
The intelligent gateway 102 may send an instruction to the intelligent terminal 104, collect data of each intelligent terminal 104, and upload the data to the platform of the internet of things in a centralized manner, where in practical application, the intelligent gateway 102 may be implemented by an independent server or a server cluster formed by a plurality of servers, or may be a system of a terminal and a server.
In one embodiment, as shown in fig. 2, a method for controlling power consumption of an intelligent gateway is provided, and the method is applied to the intelligent gateway 104 in fig. 1 for illustration, and may include the following steps:
step 201, obtaining the number of tasks corresponding to the tasks to be processed in the task execution queue.
Specifically, after acquiring the task to be processed, the intelligent gateway may add the task to be processed to the task execution queue. The task to be processed can be a task generated after the intelligent gateway responds to the request of the intelligent terminal, such as a sensing data acquisition task, an electric energy distribution task and the like; the tasks generated in the data processing process in the intelligent gateway can be also used, for example, tasks such as data analysis on collected sensing data, uploading analysis results to an internet of things platform and the like are performed.
In practical application, the intelligent gateway can obtain the number of tasks corresponding to the tasks to be processed in the task execution queue. Specifically, for example, the intelligent gateway may acquire the number of tasks at preset time intervals; or, the time for acquiring the number of tasks may be determined according to the current electric quantity of the intelligent gateway, for example, when the electric quantity is higher than a first threshold value, the number of tasks may be acquired according to a first preset frequency, and when the electric quantity is lower than a second threshold value, the number of tasks is acquired according to a second preset frequency, where the first threshold value is greater than the second threshold value, and the first preset frequency is greater than the second preset frequency.
Step 202, if the number of tasks is smaller than a preset number threshold, entering an idle mode.
As an example, the idle mode may be a mode in which the overall power consumption of the intelligent gateway is lower than the preset power consumption, and in the idle mode, the intelligent gateway may not process the task to be processed in the task execution queue, or may process the task with low power consumption.
After determining the number of tasks, the intelligent gateway may compare the number of tasks to a preset number threshold. If the number of the tasks is greater than or equal to the number threshold, the intelligent gateway can continue to process the tasks to be processed in the task execution queue according to the current mode; if the number of tasks is less than the number threshold, an idle mode may be entered.
In a specific implementation, the number threshold may be preset by a user, for example, the number threshold may be 1, and the idle mode may be entered when the number of tasks is 0. Or, the number threshold may be determined based on the current electric quantity of the intelligent gateway, for example, a corresponding relationship between the number threshold and the current electric quantity of the intelligent gateway may be preset, and then the corresponding number threshold may be queried based on the current electric quantity, so that the intelligent gateway may determine whether to enter the idle mode based on different electric quantities.
And 203, switching the idle mode into a sleep mode when the duration of the idle mode reaches a preset duration.
The power consumption corresponding to the sleep mode is smaller than the power consumption corresponding to the idle mode. In the sleep mode, the intelligent gateway can not process any task, or can not respond to information or instructions from the intelligent terminal or the platform of the internet of things, the intelligent gateway is in the working state with the lowest power consumption at the moment, in the sleep mode, the processor core and the programmable logic of the intelligent gateway hardly consume energy, and only part of the internal controller and the wake-up logic of the gateway work normally.
Specifically, after entering the idle mode, the intelligent gateway may record the duration of the idle mode, and when the duration of the idle mode reaches a preset duration, the current idle mode of the intelligent gateway may be switched to a sleep mode with lower power consumption. Specifically, the intelligent gateway is switched to the sleep mode, so that the system context data can be stored when the system enters the sleep mode by suspending the system at an application layer.
In this embodiment, an intelligent gateway powered by solar energy or powered by induction is adopted, so that the number of tasks corresponding to tasks to be processed in a task execution queue can be obtained, if the number of tasks is smaller than a preset number threshold, an idle mode is entered, and when the duration of the idle mode reaches a preset duration, the idle mode is switched to a sleep mode, so that when the number of tasks to be processed is small, the overall power consumption of the intelligent gateway can be effectively reduced by switching different modes, more electric quantity is distributed to the intelligent terminal, and the application range of the intelligent terminal is enlarged.
In one embodiment, the method may further comprise the steps of:
when the current wake-up information is detected, determining whether the current wake-up information is matched with preset wake-up information or not; if yes, the sleep mode is switched to a working mode, and the task to be processed in the task execution queue is processed; if not, executing the power-on reset operation.
As an example, the wake-up information may also be referred to as an interrupt source, and may be information for triggering the intelligent gateway to switch from sleep mode to other modes.
In a specific implementation, when the intelligent gateway is in the sleep mode and detects the current wake-up information, it may be determined whether the current wake-up information matches with the preset wake-up information. If yes, the sleep mode can be switched to the working mode, and the task to be processed in the task execution queue is started to be processed; if not, executing the power-on reset operation, and entering a normal power-on reset starting process.
In this embodiment, whether to switch the sleep mode to the working mode can be determined by determining whether the current wake-up information is matched with the preset wake-up information, so that the accuracy of mode switching is improved, and the consumption of redundant electric quantity is avoided.
In one embodiment, the wake-up information may include a wake-up time, and the determining whether the current wake-up information matches the preset wake-up information may include the following steps:
if the current wake-up time is the same as the preset wake-up time, determining that the current wake-up information is matched with the preset wake-up information.
In practical applications, the wake-up information may be a wake-up time, for example, wake-up when a set fixed interval time arrives. When the current wake-up information is detected, the intelligent gateway can judge whether the wake-up time in the current wake-up information is the same as the preset wake-up time, and if the current wake-up time is the same as the preset wake-up time, the intelligent gateway can determine that the current wake-up information is matched with the preset wake-up information, and then can switch the sleep mode into the working mode.
In the embodiment, by comparing the wake-up time, whether the wake-up information is matched or not can be quickly and accurately determined, excessive calculation is not needed, and the power consumption of the intelligent gateway is effectively reduced.
In one embodiment, when the duration of the idle mode reaches a preset duration, the idle mode is switched to the sleep mode, which may include the following steps:
when the duration of the idle mode reaches a preset duration, determining wake-up information for triggering the intelligent gateway to switch from the sleep mode to the working mode; determining a wake-up entry address corresponding to a wake-up operation process and context data corresponding to a current task to be processed; and after the awakening information, the awakening entry address and the context data are stored, controlling the processor of the intelligent gateway to enter a sleep mode.
When the intelligent gateway detects that the duration of the idle mode reaches the preset duration, the intelligent gateway can determine wake-up information for triggering the intelligent gateway to switch from the sleep mode to the working mode, and the interrupt source is set. After the wake-up information is preset, the intelligent gateway can determine a wake-up entry corresponding to the wake-up operation process and context data corresponding to the current task to be processed. After the wake-up information, the wake-up entry address and the context data are stored in the preset module, the processor of the intelligent gateway can be controlled to enter the sleep mode. Specifically, for example, the context data may be saved to the synchronous dynamic random access memory, and the system clock is turned off to control the processor of the intelligent gateway to enter the sleep mode.
In this embodiment, when the duration of the idle mode reaches a preset duration, wake-up information for triggering the intelligent gateway to switch from the sleep mode to the working mode is determined, wake-up entry addresses corresponding to wake-up operation processes and context data corresponding to a task to be processed currently are determined, after the wake-up information, the wake-up entry addresses and the context data are stored, a processor of the intelligent gateway is controlled to enter the sleep mode, a basis can be provided for subsequent rapid data recovery and entry into the working mode, and electricity consumption caused by mode switching is effectively reduced.
In one embodiment, the switching the sleep mode to the working mode may include the following steps:
jumping to a prestored wake-up entry address; and starting a wake-up operation process corresponding to the wake-up entry address to restore the context data pre-stored in the synchronous dynamic random access memory.
As an example, the wake entry address may be a preset link address, and the wake entry address may be an address in the local device or a link address on the server. The page corresponding to the link address may be deployed with a wake-up operation process. The context data may be data of the intelligent gateway before entering the sleep mode, such as data processed by the intelligent gateway and data to be processed when the intelligent gateway is about to enter the sleep mode.
In a specific implementation, if it is determined that the current wake-up information matches the preset wake-up information, the method may jump to a wake-up entry address stored in the memory, and start a wake-up operation process corresponding to the wake-up entry address, and restore context data stored in advance in a synchronous dynamic random access memory (synchronous dynamic random-access memory, SDRAM) through the wake-up operation process.
In this embodiment, by jumping to the pre-stored wake-up entry address, starting the wake-up operation process corresponding to the wake-up entry address, and restoring the context data pre-stored in the synchronous dynamic random access memory, the data restoration can be quickly performed, and the sleep mode is switched to the working mode.
In one embodiment, when the duration of the idle mode reaches a preset duration, the method enters a sleep mode, and further includes the following steps:
and determining external equipment electrically connected with the intelligent network, and controlling the external equipment to enter a sleep mode.
In a specific implementation, when the duration of the idle mode is detected to reach the preset duration, the intelligent gateway may further determine an external device electrically connected to the intelligent gateway, where the external device electrically connected to the intelligent network may be powered by the intelligent gateway, and the external device may include an intelligent terminal. After determining the electrically connected external device, the intelligent gateway may send a sleep command to the external device, and may control the external device to enter a sleep mode.
In this embodiment, by determining the external device electrically connected to the intelligent network and controlling the external device to enter the sleep mode, the external device and the intelligent gateway can enter the sleep mode together, and when the intelligent gateway does not perform data processing, the power consumption of the external device is reduced, so that the overall power consumption is effectively reduced.
In one embodiment, the method may further comprise:
in the idle mode, updating the task number according to a preset time interval; and if the current task number is greater than or equal to the number threshold, switching the idle mode into a working mode, and processing the task to be processed in the task execution queue.
As an example, the operation mode may be a mode in which the intelligent gateway processes tasks in a normal data processing manner, for example, a mode in which the intelligent gateway operates according to rated parameters of the intelligent gateway.
In the idle mode, the intelligent gateway can update the number of tasks corresponding to the tasks to be processed in the task execution queue according to a preset time interval, and if the current number of tasks is greater than or equal to a number threshold, the idle mode can be switched to a working mode to process the tasks to be processed in the task execution queue.
In this embodiment, when the current number of tasks is greater than or equal to the number threshold, the idle mode may be switched to the working mode, and the tasks to be processed in the task execution queue are processed, so that the power consumption of the intelligent gateway is reduced, and meanwhile, task processing may be performed in time, thereby improving the processing efficiency of the intelligent gateway.
In order that those skilled in the art may better understand the above steps, an embodiment of the present application will be described below by way of an example, but it should be understood that the embodiment of the present application is not limited thereto.
As shown in fig. 3, after the system on the intelligent gateway starts to initialize, the system may execute a preset process, call a rest_init () function in a kernel initialization function init/main.c through the preset process, and after the init process is activated in the rest_init () function, the init process may call a corresponding system initialization program to complete initialization for the user space. During the initialization process, the preset process may execute the cpu_do_idle () function, and enter an idle process state. Specifically, the preset process may also be called a number 0 process or an idle process, where the process priority of the idle process is lower, and when no task to be processed is in the task execution queue of the system or the number of tasks is less than the number threshold, the idle process may be executed. The idle mode switching can be realized in a cpu_do_idle () function through the preset process, and the idle mode is entered when no task is executable temporarily, and the idle mode can be exited when the task execution queue is non-empty, and a task scheduling mode combined with DVS (dynamic voltage scaling ) technology is adopted to respond to a task request.
When the duration of the idle mode reaches a preset duration and the latter is greater than a preset threshold, as shown in fig. 4, the system may send a sleep instruction requesting to switch to the sleep mode to the kernel of the intelligent gateway, after receiving the sleep instruction, the kernel may call a message function to send a sleep notification to the external device, control the external device to enter the sleep mode, and determine whether the power consumption management message function returns a message indicating success to the kernel, if not, it may determine that the process of entering the sleep mode by the external device is wrong, and return a step of calling the message function to send the sleep notification to the external device. If so, the setting parameters of the external device register can be saved, the interrupt source of the current allowed wake-up sleep state of the system (namely, the wake-up information is preset), the contents of the general register and the coprocessor of the CPU are saved, the SDRAM is set to be in a self-refresh mode, and then the sleep mode can be entered. In one example, a GPIO (General purpose input/output) interrupt or RTC (Real Time Clock) interrupt may be used when setting the interrupt source.
As shown in fig. 5, when the intelligent gateway receives the interrupt source in the sleep mode, the intelligent gateway may start to perform sleep reset, and first, the intelligent gateway may determine whether the interrupt source currently received is a preset interrupt source capable of waking up in the sleep mode, and determine whether the interrupt source is currently in the sleep wake-up start process.
If not, the current interrupt source can be determined to be used for triggering the intelligent gateway to carry out the process of power-off reset and re-power-on. If yes, the user can jump to a preset wake-up entry address, start a corresponding wake-up operation process and carry out the scene data, the processor and the context data of the peripheral registers which are saved when the user can resume dormancy. And the message function can be called to wake up the external equipment, and whether the message function returns a success indication is judged, if not, the wake-up error is determined; if so, determining that the intelligent gateway has restored to the environment before entering the sleep mode. In practical application, the process of switching the intelligent gateway from the sleep mode to the working mode can be similar to the first power-on starting process, but in the process of switching the intelligent gateway from the sleep mode to the working mode, the intelligent gateway also needs to make a judgment on the starting process, and the current starting process is judged to be the process of waking from the sleep mode or the process of resetting and re-powering the system.
It should be understood that, although the steps in the flowcharts of fig. 2-5 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least a portion of the steps of fig. 2-5 may include multiple steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor does the order in which the steps or stages are performed necessarily occur sequentially, but may be performed alternately or alternately with at least a portion of the steps or stages in other steps or other steps.
