Optionally, in an embodiment of the present invention, the asynchronous unblock processing mode that described collecting unit 203 adopts is: execute after current acquisition tasks sheet A1, as insert the task sheet B1 that the current task A of a priority ratio is high, proceed to the sheet B1 that executes the task, execute after task sheet B1, the priority of the task sheet that the task sheet of other tasks inserts or insert as not having does not have the priority of task A high, other task sheets of the A that continues in order to execute the task; Wherein, task sheet A1 is the task sheet of task A.
As shown in Figure 3, be the present embodiment power quality data Real-time Collection schematic diagram.As seen from Figure 3, the power quality data Real-time Collection principle of the present embodiment is based on task, and adopts the disposal route of asynchronous unblock to realize the collection of data.
As shown in Figure 3, thread 1, thread 2 ... thread n, represent that harvester is to the thread of operating system application, timeslice 1, timeslice 2 ... timeslice n, expression operating system is given the time of thread, task 1, task 2 ... task n, the acquisition tasks that represents harvester, by thread 1 to thread n, obtain the execution resource (time) of CPU, and according to the algorithm of priority flexible strategy, the execution resource of the CPU obtaining is distributed to different tasks, task just can obtain the right that circulation is carried out like this.
Task has priority, the default support 3 class priority of the present embodiment, that is: limit priority, normal priority and lowest priority, the priority of task that priority is high is processed, the processing time that the task of equal priority obtains is basic identical, the CPU time that all threads of all task sharings obtain, carry out concrete acquisition tasks, acquisition tasks is taked asynchronous unblock mode, so just can stop in real time the execution of any task, insert any urgent acquisition tasks in real time, such as: quality of power supply real time data, event data, clock data, supplemental characteristic etc.
The present embodiment merges " CPU time modular concept, asynchronous unblock communication process modular concept, task burst principle, task priority transaction module principle that centralized and unified distribution is obtained " and, in quality of power supply acquisition applications, has realized well the real-time property collection of large capacity collection point.
1, the CPU time modular concept that centralized and unified distribution is obtained
By the mode application CPU time of the journey that bursts at the seams, the thread of opening is more, relatively many, the approximate computing formula of CPU time of application, the Thread Count B that the Thread Count A that the operating system of harvester has been moved, the CPU of harvester open, so, the ratio of the CPU time that harvester obtains is C, and C=B/ (A+B) calculates and can find out thus, the Thread Count B that harvester leaves is more, and the CPU time of obtaining is relatively many.
2, asynchronous unblock communication process modular concept
Prerequisite and hypothesis:
A, do not carry out thread switching, do not consider the time that thread switches;
The instruction that b, Multithread Synchronization Program of the prior art and the application's technical scheme is carried out is taken time identical, (it is nanosecond that the time of expending is carried out in instruction to carry out spent time much smaller than the spent time of collection communication of instruction, the time Millisecond that signal post expends), ignoring execution instruction takes time;
C, the time overhead that only consideration is communicated by letter, do not consider the time overhead that data are stored;
D, do not consider the obstruction that communication failure causes;
The time that e, collection communication expend is T,
Synchronous blocking model approximate formula:
wherein, Ti represents the collection communication time that i task spends, altogether K task.
Asynchronous unblock model approximate formula: T=MAX (Ti);
The call duration time of synchronous blocking model be all call duration times and, and the call duration time of asynchronous unblock model is substantially equal to the call duration time of single-point, what this species diversity was far away at network path, network speed shows the in the situation that of slower is more obvious.
3, task burst principle
Task is divided into a lot of little task sheets, and each task sheet execution time remains on 20ms between 100ms as far as possible, is no more than 100ms.
4, task priority transaction module principle
The priority of task determines by the flexible strategy of task, and the flexible strategy of the task that priority is higher are higher, and the flexible strategy of the task that priority is lower are lower, and the ratio of the task acquisition time that priority is high is higher, obtains the chance carried out just high.
Task acquisition time ratio D, the flexible strategy of task are E,
wherein, Ei represents the flexible strategy of i task, altogether K task.
Above-mentioned analysis is known, the in the situation that of many in collection point, guarantee real-time data collection, guaranteed especially the high data acquisitions of requirement of real-time such as quality of power supply real time data, event data, clock data, supplemental characteristic.
Finally it should be noted that: above-mentioned only in order to the present invention to be described and unrestricted technical scheme described in the invention; Although this instructions has been described in detail to the present invention, but, those skilled in the art still can modify or be equal to replacement the present invention, and all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in claim scope of the present invention.
