Problems solved by technology

[0010] 1. Unable to realize the planning and scheduling of arbitrarily complex timing tasks, lack of flexibility;
[0011] 2. Even for tasks executed at the same time every day, there will be time jumps at the beginning and end of daylight saving time;
[0013] 4. Use a single background thread to schedule and execute all scheduled tasks, and the processing ability is weak. When it takes a long time to execute a certain task, it is easy to cause time drift, that is, it is easy to delay the execution of other tasks;

[0049] The first embodiment provided by the present invention, such as figure 2 shown, including:

[0050] In step S201, the main thread registers a timed task, specifies a timed iterator, and puts the timed task into a task queue.

[0051] Step S202, waking up all the background threads in the waiting state, and then ending the main thread.

[0052] Step S203, the awakened background thread participates in thread competition, and only one background thread obtains the right to schedule a timed task.

[0053] When it is confirmed that the task queue is not empty, step S204 is executed, that is, the background thread that acquires the right to schedule a timed task takes out the timed task with the earliest execution time from the task queue;

[0054]Step S205, judging whether the execution time of the fetched timing task is greater than the current time, if greater than the current time, execute step S206, that is, wait, the waiting time is the execution time minus the curr...

Abstract

The present invention relates to a method for planning and scheduling timed task. Its kernel lies in that based on timing iterator it utilizes at least two line processes to schedule and execute plan-scheduled timed task. Said invention can make the plan be self-contained by means of mode of timed iterator, so that it is favorable for implementing any complex plan. Besides, when the timing iterator is implemented, it can use a calendar algorithm, so that it can eliminate deviation of daylight saving time, and can ensure planning accuracy.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for planning and dispatching timed tasks. Background technique [0002] With the development of information technology, the demand for planning and scheduling tasks is becoming more and more extensive. For example, enterprises need to plan and schedule each purpose or batch processing at night; users need to schedule alarm times according to the agreed schedule, and so on. [0003] The first prior art related to the present invention is a technical solution based on Java application program to realize task planning and scheduling. In this solution, a timer framework is introduced. Using this timer framework can make it easier for programmers to plan simple tasks. . In the Java timer framework, a queue is used to store all timing tasks, and a background thread is used to complete the scheduling and execution of all tasks. Its processing flow is as figure 1 shown, including: ...
