Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the intelligent development of the instrument, the intelligent functions of the instrument are more and more, and the software control program in the instrument is more and more complex. The resources on the micro control unit of the meter and the energy of the battery are limited without increasing the hardware cost. Therefore, in order to increase the battery life, most meters reduce energy consumption by using a low power consumption mode. Currently, most meters are in low power consumption mode in idle state. Besides, the instrument realizes awakening by setting different timing cycles and executes tasks after awakening. When an instrument is abnormal, for example, the instrument does not enter a low power consumption mode for a long time, the prior art generally uses a watchdog to realize abnormal reset.
In the actual implementation process of the meter, the meter is required to be in a low power consumption state as much as possible, and the design of a software control program is relied on. However, the unreasonable software control program may cause problems such as frequent wakeups, task deadlock, and the like, and cause problems such as power consumption increase, and even failure to reset after an exception occurs. Therefore, how to reasonably design a software control program of the instrument and reduce the power consumption of the instrument becomes an urgent problem to be solved.
In order to solve the problems, the application provides an instrument control method. The method and the device adopt a task management mode to divide and manage the tasks in the instrument. The tasks of the meter are divided into interrupt tasks and timing tasks according to any priority, real-time requirements and execution time. The interrupt task is triggered by an interrupt mode, and the timing task is triggered by a timer. According to the method and the device, through the division and execution of the tasks, the time of the low power consumption state of the instrument is increased to the maximum extent on the premise of ensuring the optimal execution of the functions. Meanwhile, the meter also counts the time length of non-dormancy, and when the meter does not enter a low-power consumption state for a certain continuous time, the reset processing is carried out, so that the reliability of low power consumption is improved.
The technical solution of the present application will be described in detail below with specific examples. These particular embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments.
In the present application, a meter is used as an execution subject, and a meter control method according to the following embodiment is executed. Specifically, the execution body may be a hardware device of the meter, or a software application in the meter, or a computer-readable storage medium or a chip on which a software application implementing the following embodiments is installed.
Fig. 1 shows a flowchart of a meter control party according to an embodiment of the present application. As shown in fig. 1, with the meter as the execution subject, the method of this embodiment may include the following steps:
s101, initializing a task triggering mode according to task priority and execution time consumption of the task, wherein the triggering mode comprises interruption mode triggering and timer triggering, the task priority of the task triggered by the interruption mode is high, the execution time consumption is short, and the task priority of the task triggered by the timer is low and/or the execution time consumption is long.
In this embodiment, the meter classifies and initializes the tasks according to the task priority and the execution time consumption.
Aiming at tasks with high priority, high real-time requirement and short execution time, the instrument initializes the tasks into an interrupt task. The interrupt task needs to be triggered by means of an interrupt. The interrupt tasks include on-off valve execution, key detection, metering pulse signal detection, external alarm detection, and the like. Specifically, the meter assigns an interrupt signal to each interrupt task. The meter may determine the specific triggered interrupt task from the interrupt signal.
Tasks other than interrupt tasks, which are typically not as high in priority, do not require real-time completion of the tasks, at which point the meter may initialize these tasks as timed tasks. The timing task needs to be triggered by a timer. The timing tasks can comprise acousto-optic reminding tasks, liquid crystal display tasks, settlement tasks, storage tasks, power supply detection tasks, local communication tasks, remote communication tasks, event processing tasks and the like. Specifically, the meter sets a timer for each timing task. The meter may determine the timing task triggered by the timer based on the timer. When timing requirements of a plurality of timing tasks are consistent, the meter can also set the same timer for the plurality of timing tasks. At this time, when the timer finishes timing, the plurality of timing tasks are triggered simultaneously.
The real-time requirement of the timing task is low, so that the instrument can adjust the suspension time of the instrument by adjusting the timing time of the timer. For example, when there are multiple timed tasks, the meter may approximate the times at which the tasks are triggered by setting the time of the timer. Furthermore, the meter can process the tasks more intensively, so that frequent awakening is avoided.
In the timing task, the execution of the task is time-consuming. For a timing task with short time consumption for task execution, the instrument can complete the execution of the timing task after the timing task is triggered. For example, as shown in task 3 in fig. 2. When task 3 is triggered, the meter executes task 3 until task 3 completes execution.
However, for an interrupt task that takes a long time for task execution, if the meter executes the interrupt task until completion after the interrupt task is triggered, a problem may occur in that the execution time course of the interrupt task is interrupted. Aiming at the problem, the instrument avoids the instrument from being hung for too long time by dividing the interrupt task into a plurality of task segments and using a timer to trigger execution for a plurality of times. The execution of this interrupt task may be as shown in task 2 in fig. 4. The specific process can comprise the following steps:
step 1, dividing the task into a plurality of task segments in a multi-segment execution mode according to the execution time consumption of the task, wherein the execution time length of the task segments is a first preset time length, and the execution interval of the task segments is a second preset time length.
In the step, the instrument divides the interrupt task into a plurality of task segments according to a first preset time length, and the execution time length of each task segment is the first preset time length. The first predetermined duration is a shorter duration.
And 2, triggering the task according to the interrupt triggering instruction.
In this step, the instrument triggers the execution of the task by interrupting the trigger instruction. When the task is triggered, the timer for the task is triggered at the same time.
And 3, triggering each task segment of the task one by one according to a timer triggering instruction, wherein the triggering interval of the timer triggering instruction is a second preset time length.
In this step, after the timer of the task is triggered, the meter triggers the execution of each task segment at regular time according to the timer triggering instruction. And the second preset time length is the dormancy time length between the two task segments. In particular, the trigger may be used to trigger a start execution of a task and an end execution of the task. In the process, the meter starts executing the task or stops executing the task only according to the trigger instruction of the timer. The specific execution of the task is determined according to the actual execution of the meter.
For example, when the first preset duration of the meter is 1 second and the second preset duration is 2 seconds, the meter triggers a task every 2 seconds. The meter executes 1 second after each trigger task. When the task needs to be executed for 5 seconds, the instrument triggers 5 times of tasks, and the task is executed and completed. If in the 5-second execution, the meter has problems of resource occupation and the like, and the task is delayed to be completed. The meter will perform the task again for 1 second after a 2 second interval after the 5 th execution is complete.
In addition, for a timing task which takes a long time for task execution, if the meter continues to execute the timing task after the task is triggered until the task is completed, the meter may also have a problem of suspending the long process. In response to this problem, the meter may also divide the timing task into a plurality of task segments and trigger the timer to complete execution multiple times. The execution of this interrupt task may be as shown in task 4 in fig. 2. The specific process can comprise the following steps:
step 1, dividing the task into a plurality of task segments in a multi-segment execution mode according to the execution time consumption of the task, wherein the execution time length of the task segments is a first preset time length, and the execution interval of the task segments is a second preset time length.
In the step, the instrument divides the timing task into a plurality of task segments according to a first preset time length, and the execution time length of each task segment is the first preset time length. The first predetermined duration is a shorter duration.
And 2, triggering each task segment of the task one by one according to a timer triggering instruction, wherein the triggering interval of the timer triggering instruction is a second preset time length.
In this step, after the timer of the task is triggered, the meter triggers the execution of each task segment at regular time according to the timer triggering instruction. And the second preset time length is the dormancy time length between the two task segments. In particular, the trigger may be used to trigger a start execution of a task and an end execution of the task. In the process, the meter starts executing the task or stops executing the task only according to the trigger instruction of the timer. The specific execution of the task is determined according to the actual execution of the meter.
S102, obtaining a mark field, wherein the mark field comprises a preset number of mark bits, each mark bit uniquely corresponds to one task, each mark bit comprises 0 and 1, when the mark bit is 0, the mark field indicates that the task corresponding to the mark bit is completed, and when the mark bit is 1, the mark field indicates that the task corresponding to the mark bit is being executed.
In this embodiment, a flag field is provided in the meter. Each flag bit in the flag field corresponds to only one task. When the flag bit indicates 1, it indicates that the task corresponding to the flag bit in the meter is being executed, i.e., the task is in a suspended state. When the flag bit shows 0, it indicates that the task corresponding to the flag bit in the instrument has been completed. And after the instrument acquires the mark field, determining the state of each task in the instrument according to the value of each mark bit in the mark field.
S103, judging whether all the zone bits in the zone field are 0, and entering a low power consumption state when all the zone bits in the zone field are 0.
In this embodiment, after the meter acquires the flag field, the value of each flag bit in the flag field is determined. When the meter determines that all the flag bits in the flag field are 0, the meter enters a sleep state, i.e., a low power consumption state. When the meter determines that the flag bit in the flag field is 1, the meter is in a suspended state and cannot enter the sleep state.
According to the instrument control method, the instrument classifies the tasks and initializes the tasks according to the task priority and the execution time consumption. Aiming at tasks with high priority, high real-time requirement and short execution time, the instrument initializes the tasks into an interruption task. Tasks other than tasks are interrupted and the meter can initialize these tasks as timed tasks. A meter get flags field. The meter determines the value of each flag bit in the flag field. When the meter determines that all the flag bits in the flag field are 0, the meter enters a sleep state. When the meter determines that a flag bit of 1 exists in the flag field, the meter is in a suspended state. In the application, the task is divided into the interrupt task and the timing task, so that the interrupt task can be timely and quickly executed, the timing task can determine the execution time as required, the instrument is prevented from being frequently awakened after entering sleep, and the reliability of low power consumption is improved.
Fig. 3 is a flowchart illustrating another meter control method according to an embodiment of the present application. On the basis of the embodiment shown in fig. 1, as shown in fig. 3, the instrument is taken as an execution subject, and in this embodiment, the task and the triggering thereof may include:
s201, acquiring a trigger instruction, wherein the trigger instruction is triggered by interruption or by a timer, and the trigger instruction comprises a task to be executed.
In this embodiment, the meter acquires an interrupt signal, and generates a trigger instruction according to the interrupt signal, where the trigger instruction is used to trigger an interrupt task. The meter can determine the interrupt task corresponding to the interrupt signal according to the interrupt signal. The meter determines the interrupted task as a task to be performed.
Or, the meter can also acquire a timing signal of the timer, and when the timing of the timer is finished, the meter generates a trigger instruction according to the timing information, wherein the trigger instruction is used for triggering a timing task. The meter may determine the corresponding timing task based on the timer. The meter determines the timing task as a task to be performed.
And S202, exiting the low power consumption state according to the trigger instruction, and executing the task to be executed.
In this embodiment, when the trigger instruction is generated, the meter is woken up from the sleep state. The meter exits the low power state and begins executing the task to be executed.
When the meter starts to execute the task to be executed, the meter sets the flag bit corresponding to the task in the flag field to 1. At this point, the meter is in a suspended state.
And after the instrument finishes the task to be executed, the instrument executes the start operation of the mark position and sets the mark position to be 0.
In one example, when the task to be executed is an interrupt task, the execution of the interrupt task may be as shown in task 1 in fig. 4. The execution of the interrupt task takes less time. For example, when the interrupt task is a metering pulse, the interrupt task is performed by simply incrementing the counter value by one.
In another example, when the task to be executed is a timing task, the execution of the interrupt task may be as shown in task 3 in fig. 2. The execution of this interrupt task takes a long time. Therefore, the meter needs to perform the timing task dispersedly to avoid that a plurality of timing tasks which take a long time to perform are performed continuously, which results in that the meter is suspended for a long time and an abnormality occurs.
And S203, determining related tasks according to the tasks to be executed.
In this embodiment, there may be dependencies between the various tasks in the meter. For example, for a metering pulse, when the accumulated value reaches a certain value, the meter may need to perform storage, calculation, and other tasks. In this case, the tasks such as storage and calculation are related to the metering pulse task.
Therefore, after the meter determines the task to be executed, the meter needs to determine the related task and the preset trigger condition of the related task according to the task to be executed.
And S204, establishing a timer of the related task according to the preset trigger condition and the related task.
In this embodiment, since the execution of the related task generally has no real-time requirement, the related task may be a timing task. When a task to be executed has a relevant task, the meter can determine a preset trigger condition of the relevant task according to the relevant task. And when the task to be executed meets the preset triggering condition, the instrument triggers the related task.
Both interrupt tasks and timed tasks may have related tasks and both may trigger related tasks. The related tasks may be as illustrated by task 2 in fig. 4 and task 4 in fig. 2. Wherein, task 2 is the related task triggered by the interrupt task, and task 4 is the related task triggered by the timing task.
And when the related task is triggered, a timer corresponding to the related task is established. In this case, the related task is called a timing task to be started, and waits for the timer to finish timing and trigger as in other timing tasks.
S205, obtaining the suspension duration, wherein the suspension duration is the duration that the flag fields are not all 0.
In this embodiment, the meter counts the duration of continuous suspension. The hang time is the continuous time during which the meter has not gone to sleep. I.e. the duration for which the flag fields of the meter are not all 0.
And S206, when the suspension duration is greater than or equal to a third preset duration, executing reset protection.
In this embodiment, when the suspension duration is longer than a third preset duration, the meter considers that the task execution is abnormal. Namely, the problems of deadlock of tasks and the like in the instrument can exist. At this point, the meter assumes that normal execution will not go to sleep. The meter performs reset protection. The third preset time length is determined according to the longest task execution time and is the time length obtained after the allowance time is added on the basis of the longest task execution time.
According to the instrument control method, the instrument acquires an interrupt signal and generates a trigger instruction according to the interrupt signal, and the trigger instruction is used for triggering an interrupt task. Alternatively, the meter may also obtain a timing signal of a timer, and the triggering instruction is used for triggering a timing task. When the trigger instruction is generated, the meter is awakened from the sleep state and starts to execute the task to be executed. When a task to be executed has a relevant task, the meter may determine a preset trigger condition of the relevant task according to the relevant task. And when the task to be executed meets the preset triggering condition, the instrument triggers the related task. The meter counts the duration of continuous hang up. And when the suspension duration is longer than a third preset duration, the instrument executes reset protection.
