Abstract
The invention provides a thread pool structure of a video monitoring platform system and a realizing method. The thread pool structure provided by the invention comprises a managing thread, a task queue, an idle thread queue, a binding task thread queue and an information callback. The method provided by the invention comprises the following steps of: obtaining tasks from the task queue and classifying the tasks according to task types; binding thread tasks and binding the tasks with the thread; adding the thread into the binding task thread queue or applying an idle thread executing task and adding an executing task thread into a busy thread queue; after executing tasks by the thread, returning all tasks back to a thread pool. The method provided by the invention can avoid the instability and expenditure caused by frequently establishing and destroying threads and the error of the up-application does not cause the abnormality of the thread pool; the method provided by the invention constructs a general thread pool system structure so that developers can conveniently and rapidly develop application services which are suitable for large scales and are stably developed in the system; the structure of the thread pool has a high abstractness so that the work is simplified and the work efficiency is improved.
Description
Technical field
The present invention relates to the technical field of video monitoring, is a kind of thread pool structure and implementation method that is applicable to the multithreading processing environment, the video monitoring platform system of stable operation can be provided specifically.
Background technology
Linux is as the system platform of server, the general application services that all need ask operation in highly reliable 7*24 hour, wherein network communication services has accounted for very big proportion again, and this has just proposed very high requirement to aspects such as the concurrent processing ability of these application systems, stability.Generally,, generally can adopt multithread mode, but this pattern consumption is too many in time or the resource created and destroy on the thread, so adopt the thread pool mode in order to satisfy the requirement of application program on performance.
Thread pool is a kind of multithreading processing form, adds task to formation in the processing procedure, wakes these tasks of thread execution then when demand is arranged up.The thread of thread pool all is a background thread. each thread all uses the storehouse size of configuration, with the priority operation of acquiescence, and is in the multiple thread units. be applicable to threading models such as boss/work, the producer/consumer.
If when all threads of thread pool all have task, thread pool will be created the new thread of some, but the number of thread surpasses maximal value never.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of thread pool structure and implementation method that is applicable to the multithreading processing environment, the video monitoring platform system of stable operation can be provided.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
The thread pool structure of video monitoring platform of the present invention system, comprise: management thread, the unique thread that can operate thread and thread formation in the thread pool is responsible for all tasks in the Processing tasks formation, destroy thread according to task creation, operate corresponding thread formation; The thread array of pointers is deposited all thread pointers, is convenient to can concentrate when thread pool is destroyed the destruction thread, and employing pointer data mode applies for that a thread promptly puts into a thread, by sequence number (being array index) thread is numbered; Task queue, the interface queue unique with upper layer application is responsible for depositing the task requests of upper layer application, the employing double-linked circular list is realized, use the way to manage of first in first out, a new task at first can be delivered to task queue, and management thread obtains task from task queue then; The idle thread formation, deposit the thread pointer of idle no task, the employing double-linked circular list is realized, use the way to manage of first in first out, management thread at first obtains idle thread according to task from the idle thread formation, and allowing its readjustment of executing the task, this thread is got back in the idle thread formation after executing; The formation of binding task thread, deposit the thread pointer of binding task, the employing double-linked circular list is realized, management thread at first obtains corresponding binding thread according to task from the formation of binding task thread, and allow it carry out task bound readjustment, this thread is got back in the formation of binding task thread after executing, and up to the upper layer application unbind, thread enters the idle thread formation behind the unbind; The message readjustment after thread pool is handled the upper layer application task requests, is notified upper layer application with the result by the message readjustment.
The thread pool implementation method of video monitoring platform system may further comprise the steps:
1) upper layer application is delivered task by the thread pool task interface and is added task queue to;
2) management thread obtains task from task queue;
3) classification is handled according to task type, and binding thread task is with task and thread binding, and add this thread the formation of to binding task thread, apply for that perhaps idle thread executes the task, the thread of will executing the task is carried out the corresponding task readjustment respectively to busy thread formation;
4) return thread pool respectively after above-mentioned two corresponding thread execution tasks;
5) the Processing tasks result is notified to upper layer application by the message readjustment.
All threads that comprise management thread are the hang-up sleep state during free time, just it is waken up when needing.
Advantage and good effect that the present invention has are:
The thread pool structure and the implementation method of video monitoring platform of the present invention system can be avoided frequent instability and the expense that thread brings of creating and destroy; The mistake of upper layer application can not cause that thread pool is unusual; The present invention has made up a general thread pool architecture, can allow the exploitation personnel develop on this individual system quickly and easily and be applicable to the application service that large-scale concurrent is stable; The structure of thread pool has high abstract, and the developer need not be concerned about the concrete processing or the management logic of thread more like this, only needs to be concerned about concrete client requests task processing, thereby has simplified work, has improved work efficiency; The thread pool structure and the implementation method of video monitoring platform of the present invention system are applicable to multiple threading model, for example Boss/Work, the producer/consumer etc.
