Embodiment
Purport of the present invention is to overcome the deficiencies in the prior art, a kind of method and system avoiding mobile terminal to crash are provided, system is understood oneself and is detected cpu resource value Xm, and calculate the mean value Ym of nearest n time, such as, n can be the reference number of times of 5 times or other users needs, compare the relation of the value of Xm and Ym again, if Xm >=N*Ym terminates this process automatically, can prevent mobile phone from crashing in advance, improve Consumer's Experience.Be described in detail, to be interpretated more in-depth technical characteristic of the present invention and advantage with reference to accompanying drawing below in conjunction with embodiment.
As shown in Figure 1, a kind of method avoiding mobile terminal to crash, comprises following four steps to method flow diagram of the present invention.
Step 1 of the present invention is as follows: obtain one by one when application program for mobile terminal runs for the first time and take cpu resource value, calculate when all application programs are run for the first time and take cpu resource value summation Xm.Generally, user installation is many especially in the program of mobile terminal system, such as game, amusement, chat etc., also has the program that carries of system, obtains all systems and adds up and take cpu resource value summation Xm.
As preferred embodiment of the present invention, step 1 of the present invention specifically comprises:
Step 101. arranges a trace routine, runs application program for mobile terminal one by one, obtains the cpu resource value taken when application program is run; Such as a testing software can be installed herein, open application program one by one by testing software, obtain each application program and take cpu resource value, and each application program is taken cpu resource value record save;
Step 102. calculates when all application programs are run for the first time and takies cpu resource value summation Xm; Calculated when all application programs are run for the first time by test procedure and take cpu resource value summation Xm, calculating comprehensive Xm is herein difference between resource value in order to add up Xm and CPU; If Xm is greater than cpu resource value summation, then get the resource value that Xm is CPU; If Xm is less than cpu resource value summation, then get the value of Xm;
Step 103. will take cpu resource value summation Xm and write in initial register, after obtaining above Xm value, for subsequent use in write initial register.
In actual motion, mobile terminal changes along with the demand of user, can constantly install or unloading application program, and as can be seen here, the value of Xm is constantly change and adjustment in fact, and thus, the step 1 of method of the present invention also comprises:
Step 104. trace routine detects in real time installs or unloading with or without application program; An entertainment software has such as newly been installed, or a unloading video software etc.;
Step 105. adjustment takies the value of cpu resource value summation Xm, in write initial register.Concrete adjustment comprises:
When there being application program to install, trace routine runs new application program of installing, obtain the cpu resource value taken when application program is run, and on the upper basis taking cpu resource value summation Xm once writing initial register, increase the cpu resource value taken when new application program of installing is run, in write initial register;
When there being application program to unload, trace routine obtains the cpu resource value taken when this application program is run, and the cpu resource value taken when deducting the application program operation of unloading on the upper basis taking cpu resource value summation Xm once writing initial register, in write initial register.
Step 2 of the present invention is as follows: detect application program one by one when running, record and take cpu resource value X1 ~ Xn for n time recently, calculate the nearest mean value Ym taking cpu resource value X1 ~ Xn for n time, n is for pre-seting definite value.Such as, system can arrange nearest 5 times and take cpu resource value X1 ~ X5, so mean value Ym=(X1+X2+X3+X4+X5)/5, the value of certain n can adjust according to actual conditions, if application program takies cpu resource value stabilization, so n can be set to get mean value several times less, if application program takies cpu resource value instability, so n needs to be set to the mean value got several times more, and the mean value reference value of acquisition is larger like this.
Step 3 of the present invention is as follows: judge whether to meet Xm >=N*Ym, and N is predetermined fixed value, is, continues to detect, otherwise terminates this application program.Described N, for pre-seting, adjusts as the case may be.N can be set by the user, also can by systemic presupposition value.
As preferred embodiment of the present invention, step 3 of the present invention specifically comprises:
Step 301. obtains the maximal value Y taking cpu resource value when all application programs are run for the first time, pre-sets a positive integer N, and formula Xm >=N*Y is set up; In order to arrange the threshold values that prevents system in case of system halt when arranging formula Xm >=N*Y, when this formula is set up, the probability that system occurs to crash is smaller, when this formula is false, then there is the likelihood ratio of deadlock comparatively greatly in system, and at this time system needs take measures shutdown system or other treatment measures;
Step 302. judges the nearest mean value Ym taking cpu resource value X1 ~ Xn for n time of application program, whether meets Xm >=N*Ym, is, continues to detect, otherwise terminates this application program.Such as, n=5, so Ym=(X1+X2+X3+X4+X5)/5, if meet Xm >=N*Ym, illustrate and this time run this application program without deadlock risk, if do not meet Xm >=N*Ym, there is deadlock risk, now terminate this application program.
As shown in Figure 2, concrete implementation step is as follows for specific embodiments of the invention:
A. installation testing software or detection application; User installation detects application, and inputs N value, and N value is positive integer, is greater than several times on average takies cpu resource value Xm for judgement, and user can modify according to maloperation below this value, and detection is run in backstage always;
B., when first time opens application, what obtain each application one by one initially takies cpu resource value; When system opens application, trace routine also records Xm, records the nearest X1-X5 run for 5 times
C. write in initial register;
D. calculating all application initial resource occupation value Xm after completing;
When e. calculating the operation of a certain application program, nearest the mean value Ym taking cpu resource for 5 times, Ym=(X1+X2+X3+X4+X5)/5;
F. judge whether Xm >=N*Ym meets, and is, returns step e, otherwise perform step g;
G. return zero and send the instruction terminating this application program to CPU, CPU, terminate this program.
The present invention also discloses a kind of system avoiding mobile terminal to crash, and comprising:
Acquisition module, takies cpu resource value for obtaining one by one when application program for mobile terminal runs for the first time, calculates when all application programs are run for the first time and takies cpu resource value summation Xm;
