[detailed description of the invention]
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings and specifically Embodiment describes the present invention.
Through the analysis to user's request, find that user is typically whole task and needs the demand of tempo instructions How long if total time is acceptable, the end of task is waited for, if the time is not Acceptable, then can directly end task, and for when task processes processes the most assorted Time process slow, be not very concerned about.Therefore, the core concept of the present invention is, at tempo instructions Ask and obtains total duration of task process time initial to processor, before this total duration the first duration with Acceleration mode or at the uniform velocity mode carry out tempo instructions, and period ensures that progress does not stops, residue progress amount with At the uniform velocity mode carries out tempo instructions, and in front first duration, the tempo of tempo instructions is more than residue progress amount The tempo of tempo instructions.Further, in the process that residue progress amount is carried out tempo instructions In can ask to processor and obtain task process real surplus duration, determine with real surplus duration And update the tempo of tempo instructions.
Preferably, in order to improve user's impression, generally use relative to rear portion progress in front portion One speed faster, therefore can be arranged on front t1S is completed in time1Progress amount, at rear t2Time Inside complete S2Progress amount, at least a part of which
Further, if front portion uses acceleration mode, in order to ensure front portion phase Speed faster is used for rear portion progress, then at least need to ensure t1After the speed in moment is more than The velocity amplitude that a part at the uniform velocity uses.
t1The speed in moment Vt 1 = V 0 + a × t 1 = 2 S 1 - a × t 1 2 2 t 1 = S 1 t 1 + 1 2 a × t 1 , t1Speed after moment It is at mostTherefore it is preferably provided with
As half the time completes the 90% of whole progress in acceleration mode, second half time is in speed mode Complete the residue 10% of whole progress.
The method provided the present invention below in conjunction with the embodiment shown in Fig. 1 and Fig. 3 is described in detail, Front portion in tempo instructions is carried out in acceleration mode in the embodiment shown in fig. 1, rear portion As a example by speed mode is carried out, it is preferable that in order to improve Consumer's Experience, in the present embodiment, previous portion The negative integer that the acceleration employing divided is preset, i.e. the decrease of speed of tempo instructions during front portion, During rear portion, tempo instructions uses at the uniform velocity.
The method flow diagram that Fig. 1 provides for the embodiment of the present invention, assumes tempo instructions figure in this embodiment Shape is progress bar, at front portion time t1In carry out front S in acceleration mode1The tempo instructions of progress amount, Residue progress amount S2Tempo instructions carry out at the uniform velocity mode, pending task is page loading tasks. As shown in fig. 1, the method may comprise steps of:
In 101, ask to processor and obtained the total duration required for page loading tasks.
When just starting to load the page, when i.e. task processes and starts, need to carry out once mutual with processor, Having asked the total duration required for page loading tasks to processor, processor can be according to page to be loaded The size in face and current network speed determine the total duration required for loading tasks.
In 102, progress amount S completed according to the acceleration a preset, acceleration mode1With with accelerate The duration t of degree mode schedule instruction1, determine the initial velocity V of tempo instructions in progress bar0
Mainly use physical calculation, initial velocity V0For:
V 0 = 2 S 1 - a × t 1 2 2 t 1
In 103, according to the initial velocity V obtained0, update time t every progress and update a progress Tempo instructions in bar, the tempo instructions after updating for the ti time arrives Sti
Wherein, S ti = V 0 × ti + 1 2 a × ti 2
Ti is that i-th updates the time.
If at time t1Interior employing at the uniform velocity mode schedule indicates, then initial velocityShould Initial velocity is exactly at t1The speed of interior employing, updates time t every progress and updates in a progress bar Tempo instructions, the tempo instructions after updating for the ti time arrives Sti=V0×ti。
In 104, when it is completed between t1Time, ask to processor and obtained page loading tasks Real surplus duration t3
Due in actual task processing procedure, it is understood that there may be some situations, such as unstable properties, net The situations such as speed is unstable, the total duration needed for causing task to process changes, when i.e. originally should remain Long t2, become real surplus duration t3, therefore, carry out the most mutual with processor the most again.
In 105, utilize residue progress amount S2With real surplus duration t3Determine and update tempo instructions Tempo V.
In this step, the V determined needs to ensure at the uniform velocity to update tempo instructions with this V, it is possible to surplus Remaining duration t3Inside complete current page loading tasks, then
In 106, at rear t3Time in, every duration t update a progress bar tempo instructions, Tempo instructions after updating for the tj time arrives Stj
Wherein, Stj=S1+ V × tj, tj are that the jth in residue progress amount updates time, namely t1It After jth update the time.
If getting rid of the total duration needed for task can be caused in actual task processing procedure to process to change Situation, there is also ideal state, i.e. total duration is exactly the total duration initially determined that out, then can also Do not perform step 104, i.e. need not be at deadline t1Time, ask to processor and obtained the page to add The real surplus duration t of load task3, but utilize residue progress amount S2With residual time length t2Determine that progress refers to The tempo V shown, nowEven if it addition, perform step 104, asking also to processor The real surplus duration t obtained3It is likely to equal to t2
In flow process shown in Fig. 1, at time t1Afterwards, the most after step 105 and loading tasks terminates Before, it is also possible to ask to processor at regular intervals and obtained page loading tasks reality remain Remaining duration, then utilizes residue progress amount and real surplus duration to determine and updates the progress speed of tempo instructions Degree.If it is to say, can be stem portion by the uniform velocity carrying out the stage cutting of tempo instructions, every part be the most all According to the real surplus duration asked to processor and obtain to update the tempo of tempo instructions, i.e. t1 Constant speed part afterwards, it is understood that there may be several different tempos.
In the above-described embodiments, except being applied to the use scene of above-mentioned webpage, it is also possible to be applied to such as Mobile phone A PP (application), pc client, system operation etc. use scene, such as antivirus software entering During row virus scan, the progress for virus scan indicates, more such as when deleting big file, pin The progress deleting file indicates.The generation of progress bar and renewal can be by application, client or behaviour Make the control in system etc. or assembly performs.
For embodiment shown in Fig. 1 for a specific example, it is assumed that to accelerate in the first half time Degree mode completes the progress of front 90%, and wherein acceleration a is-2mm/s2, with even in the later half time Speed mode complete after 10% progress, page-size to be loaded is 1000KB, and current network is fast Degree is 100KB/s.
Carry out page loading at the beginning, just get size and the network speed of the page of loading, determined Become required for page loading tasks total time a length ofSo update progress in acceleration mode Time a length of 5s, update time a length of 5s of progress at the uniform velocity mode.
If the total length of progress bar is 100mm, then a length of with the progress that acceleration mode completes 90mm, a length of 10mm of progress completed at the uniform velocity mode.
The initial velocity of tempo instructions in progress bar V 0 = 2 × 90 - ( - 2 ) × 5 2 2 × 5 = 23 ( mm / s ) .
If the tempo instructions in 1s updates a progress bar, then when 1s, after renewal Tempo instructions arrives: 23 × 1+0.5 × (-2) × 12=22 (mm).
When 2s, the tempo instructions after renewal arrives: 23 × 2+0.5 × (-2) × 22=42 (mm).
When 3s, the tempo instructions after renewal arrives: 23 × 3+0.5 × (-2) × 32=60 (mm).
When 4s, the tempo instructions after renewal arrives: 23 × 4+0.5 × (-2) × 42=76 (mm).
When 5s, the tempo instructions after renewal arrives: 23 × 5+0.5 × (-2) × 52=90 (mm).
At the end of 5s, present speed is
Ask and obtained the real surplus duration of page loading tasks to processor, it is assumed that now obtain Real surplus duration identical with the duration of originally plan, be also residue 5s, then at 5s below with even Speed mode carries out tempo instructions, and when 6s, the tempo instructions after renewal arrives: 90+2 × 1=92.
When 7s, the tempo instructions after renewal arrives: 90+2 × 2=94.
When 8s, the tempo instructions after renewal arrives: 90+2 × 3=96.
When 9s, the tempo instructions after renewal arrives: 90+2 × 4=98.
