Abstract

The invention discloses a system and method for distributing tasks of a portable master station. The method comprises the steps that the task timer of each set is triggered by a corresponding task so as to start timing; a task timing finishing judgment module judges whether the tasks are finished or not according to timing counting states; when the tasks are judged not to be finished, a task executer continues to carry out execution; when the tasks are judged to be finished or the task execution is finished, the corresponding tasks are finished by a task finishing module; a multi-task redistributor is connected with the task finishing module in a receiving mode to distribute the tasks again. A plurality of timing paths are independent from one another, parallel processing is achieved, and execution of the tasks is controlled by timed time. The relative stability of task distribution of the system of the portable master station is achieved, and the system for distributing the tasks of the portable master station has the advantages of being high in efficiency, good in performance and low in cost.

Description

A kind of task distribution system and method for portable main website

Technical field

The invention belongs to electronic circuit field, more particularly to a kind of task distribution system and method for portable main website.

Background technology

In the design of portable main station system, multitask real-time control framework is used, this framework is relied primarily on Accurate clock time-sharing circuit is completing.This requires the relatively stable of Mechanism of Task Allocation.

In actual field environment, due to itself disturbing by the electromagnetic interference in work condition environment and high-frequency circuit, when Clock timing often produces deviation, causes timing unstable, causes the unstable of event task work status, can cause when serious The collapse of whole portable main station system.

In such a case it is necessary to parallel processing mechanism is introduced in timing circuit, by stable subsection timing frequency Rate, timing allocation task.

The content of the invention

It is an object of the invention to provide the task distribution system and method for a kind of portable main website are realizing portable master It is relatively stable that system task of standing is distributed, and with efficiency high, performance is good, the advantage of low cost.

Realizing a technical scheme of above-mentioned purpose is：A kind of task distribution system of portable main website is provided, it is provided with The multigroup equipment corresponding with multiple tasks, wherein every group of equipment includes：Task timer, task timing terminate judge module, Task performer, task terminate module；

The corresponding task that task timer is received according to its input triggers to start timing；

Task timing terminates the input of judge module and is connected with the outfan of task timer, receives timer counter state Whether to terminate to judge to task；

Task timing terminates judge module and is connected to provide expression times with the input of task performer in negative outfan The unclosed negative output order of business continues executing with corresponding task until the tasks carrying is finished to order about task performer；

Task timing terminates judge module and is connected to provide expression with the input of task terminate module in outfan certainly The affirmative output order that task terminates；The outfan of task performer is also connected with the input of task terminate module；

Task terminate module, when being finished when the order of output certainly is received or in task, terminates corresponding appointing Business；

The task distribution system is additionally provided with multitask redistributor, and the task terminate module for receiving each group terminates phase The signal exported after task is answered to redistribute task.

Realizing another technical scheme of above-mentioned purpose is：A kind of method for allocating tasks of portable main website is provided, is used Above-mentioned system, in the method for allocating tasks,

Per group of task timer starts timing according to the triggering of corresponding task, and exports timer counter state；

Task timing terminates judge module and receives the output timer counter state to judge whether task terminates, and accordingly The unclosed negative output order of affirmative output order or expression task that the expression task that ground provides terminates；

Task performer continues executing with corresponding task until the tasks carrying is finished according to the negative output order；

Task terminate module terminates corresponding appointing when the order of output certainly is received or when being finished in task Business；

The task terminate module for receiving each group by multitask redistributor again terminates the signal exported after corresponding task To redistribute task.

The task distribution system and method for a kind of portable main website provided as a result of the present invention, multiple timing paths Separate, parallel processing, with the execution of timing control task, realizes the relative of portable main station system task distribution Stable, with efficiency high, performance is good, the advantage of low cost.

Description of the drawings

Fig. 1 is the structural representation of the present invention.

Specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

Fig. 1 is refer to, a kind of task distribution system of portable main website is given in figure, including：First task intervalometer, Second task timer, the 3rd task timer, first task timing terminate judge module, the timing of the second task and terminate to judge mould Block, the 3rd task timing terminate judge module, first task executor, the second task performer, the 3rd task performer, first Task terminate module, the second task terminate module, the 3rd task terminate module and multitask redistributor.

Based on said system, in the method for allocating tasks of the portable main website that the present invention is provided, first task intervalometer by First task triggering starts timing, and output timer counter state to first task timing terminates judge module to judge first task When terminate, first task timing terminates the judgement output of judge module there are two, and negative output No connection first tasks are performed Device, exports Yes connection first task terminate modules certainly, and the output of first task executor also connects first task and terminates mould Block, the output connection multitask redistributor of first task terminate module redistributes task.

Second task timer starts timing by the triggering of the second task, and output timer counter state to the second task timing is tied Beam judge module is judging when the second task terminates, and the timing of the second task terminates the judgement output of judge module two, no Surely export No and connect the second task performer, certainly output Yes connects the second task terminate module, the second task performer it is defeated Go out and also connect the second task terminate module, the output connection multitask redistributor of the second task terminate module is redistributed and appointed Business.

3rd task timer starts timing by the triggering of the 3rd task, and output timer counter state to the 3rd task timing is tied Beam judge module is judging when the 3rd task terminates, and the timing of the 3rd task terminates the judgement output of judge module two, no Surely export No and connect the 3rd task performer, certainly output Yes connects the 3rd task terminate module, the 3rd task performer it is defeated Go out also the 3rd task terminate module of connection, the output connection multitask redistributor of the 3rd task terminate module is redistributed and appointed Business.

The present invention operation principle be：Using the operation principle of parallel processing timing, there is provided a kind of portable main website appoints Business distribution system and method, realizes the relatively stable of portable main station system task distribution, with efficiency high, performance is good, into This low advantage.

The present invention is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to upper State and bright many variations example is made to the present invention.Thus, some of embodiment details should not constitute limitation of the invention, this Invention is by the scope defined using appended claims as protection scope of the present invention.
