Abstract
The invention relates to a multi-task control method for an intelligent meter reading terminal. The multi-task control method for the intelligent meter reading terminal comprises a first step of establishing tasks, respectively allocating different priorities to all the tasks, and enabling each task to be independent of other tasks, a second step of dividing the processing process of the tasks into 5 states including a dormant state, a ready state, an operation state, a waiting state and an interrupted state, a third step of detecting the state of each task, enabling the task which has the highest priority and is in the ready state to be a current task, enabling the current task to operate in the operation state, and enabling the current task to enter the dormant state after operation of the current task is finished. According to the multi-task control method for the intelligent meter reading terminal, the priority of each task of the intelligent meter reading terminal is established, tasks are made to conduct the 5 states according to the sequence of the priorities based on the five states, multiple tasks can be processed simultaneously, a CPU is made can be used to the maximum extent, the processing speed is higher, and reliability is higher.
Description
Technical field:
The present invention relates to electric energy meter control field, specifically is a kind of multi-task controlling method for the intelligent meter data recording terminal.
Background technology:
The intelligent power table is a kind of metering outfit to measure by peak interval of time, and it can also reflect situations such as present load, peak load time of occurrence, phase failure decompression simultaneously.In order to need a kind of intelligent meter data recording terminal to finish this work timely and effectively with these data back power departments.This intelligent meter data recording terminal needs a lot of functions, as: except last form data content, also need some table data are handled, show at the local facilities panel, as, the meter reading that can show zero point every day freezes value, can also show power etc., so needs to handle simultaneously a lot of tasks in the program of this intelligent meter data recording terminal.
At present, the peripheral hardware of controlling in the common electric energy meter and fulfiling of task are few, it generally is the subroutine module (backstage behavior) that adopts a major cycle and several sequence calls in its control program, handle asynchronous event (foreground behavior) by Terminal Service, this control method also becomes the AM/BAM pattern.This method can be handled uncomplicated mini system, and when handling the task of above-mentioned intelligent meter data recording terminal following deficiency is just arranged:
The first, interrupt can not get timely response, the processing time is long, and this is for being unallowed under the occasion of checking meter.
The second, because the task of intelligent meter data recording terminal is too much, therefore the various possibilities that will consider are also more, if therefore the scheduling of the cpu resource of single-chip microcomputer is improper deadlock will take place, and reduce the reliability of software, cause the failure rate of intelligent meter data recording terminal higher.
Therefore, be badly in need of at present a kind of can be according to a kind of multi-task controlling method for the intelligent meter data recording terminal of actual conditions true-time operation multitask.
Summary of the invention:
The technical problem to be solved in the present invention is, overcome existing technological deficiency, provide a kind of Processing tasks speed fast, the cpu resource utilization factor is improved, thereby and make the high a kind of multi-task controlling method for the intelligent meter data recording terminal of application software moduleization reliability.
Technical solution of the present invention is, a kind of multi-task controlling method for the intelligent meter data recording terminal is provided, and it may further comprise the steps:
Step 1 is set up task, and distributes different priority for respectively each task, and is independent of one another between each task;
Step 2 is divided into 5 states with the task handling process: be respectively dormant state, ready attitude, run mode, waiting state and be interrupted attitude;
Step 3, detecting the highest and task that be in ready attitude of state, the priority of each task is current task, enters into the run mode operation, after current task has been moved, enters dormant state.
Above-mentioned a kind of multi-task controlling method for the intelligent meter data recording terminal, described step 3 also comprises: detects in real time and interrupts, if occur interrupting, outage then, current task enters and is interrupted attitude, and after interrupting finishing dealing with, current task continues operation.
Above-mentioned a kind of multi-task controlling method for the intelligent meter data recording terminal, when if described interruption makes a task higher than current task priority enter ready attitude, after interruption is finished dealing with, interrupted task is in waiting state, the task higher than current task priority enters the run mode operation, after operation was finished, interrupted task entered ready attitude.
Above-mentioned a kind of multi-task controlling method for the intelligent meter data recording terminal, when if current task makes the higher task of another priority enter ready attitude when run mode, then current task enters into waiting state, the task that another priority is higher enters the run mode operation, after finishing, current task enters ready attitude.
Above-mentioned a kind of multi-task controlling method for the intelligent meter data recording terminal, setting up in the described step 1 of task according to priority is followed successively by from high to low: desktop task, master menu task, user management task, the task of checking meter, system arrange task, system time task, system tool task, system information task, button task.
After adopting said structure, the present invention has the following advantages:
The present invention is with the various task creation priority of intelligent meter data recording terminal, according to 5 states setting task is carried out according to priority orders then, can handle multitask simultaneously, make the utilization factor of CPU obtain maximum performance, processing speed is faster, and owing to be to set 5 states, therefore program can modularization programming when software programming, the developer can be with the application program levelization of complexity, and convenient programming makes making software be more prone to design and safeguards that reliability is higher.And in the present invention, interruption is handled at first, and after interrupting handling, carries out Processing tasks according to priority once more, and interruption can in time respond, and the task that current priority is the highest also can in time be handled.
Description of drawings:
Fig. 1 is the process flow diagram of a kind of multi-task controlling method embodiment 1 for the intelligent meter data recording terminal of the present invention.
Fig. 2 is the process flow diagram of a kind of multi-task controlling method embodiment 2 for the intelligent meter data recording terminal of the present invention.
Fig. 3 is the process flow diagram of a kind of multi-task controlling method embodiment 3 for the intelligent meter data recording terminal of the present invention.
Embodiment:
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the invention provides a kind of multi-task controlling method for the intelligent meter data recording terminal, it may further comprise the steps:
Step 1, set up task, and distribute different priority for respectively each task, independent of one another between each task; The foundation of task is to come from the bottom layer driving of meter reading terminal, described bottom layer driving comprises the LCD display driver, UART drives, HC drives, RTC drives, button drives, program distributes different priority for according to actual needs different tasks, the task of Jian Liing is 9 in the method, and its priority is followed successively by from high to low: desktop task, master menu task, user management task, the task of checking meter, system arrange task, system time task, system tool task, system information task, button task.
Step 2, the task handling process is divided into 5 states: be respectively dormant state, ready attitude, run mode, waiting state and be interrupted attitude;
