图2为一个实施例中CPU监测方法的流程图。如图2所示，一种CPU监测方法，包括步骤202至步骤206。其中：Fig. 2 is a flowchart of a CPU monitoring method in an embodiment. As shown in FIG. 2 , a CPU monitoring method includes step 202 to step 206 . in:
步骤202，按照预设的第一时间间隔获取系统CPU占用率。Step 202, acquiring system CPU usage at a preset first time interval.
移动终端在运行时，移动终端内系统程序和第三方程序均会消耗移动终端内CPU(Central Processing Unit，中央处理器)资源。移动终端系统CPU占用率即为移动终端中运行的所有程序占用的CPU资源，包括系统运行程序和第三方运行程序。一般来说，系统CPU占用率越高、移动终端内运行的程序越多；系统CPU占用率越低、移动终端内运行的程序越少。移动终端可按照预设的第一时间间隔获取系统CPU占用率，预设的第一时间间隔可为用户设定的时间间隔，也可为根据历史采集时间得到的时间间隔。When the mobile terminal is running, both system programs and third-party programs in the mobile terminal will consume CPU (Central Processing Unit, central processing unit) resources in the mobile terminal. The CPU usage rate of the mobile terminal system refers to the CPU resources occupied by all programs running in the mobile terminal, including system running programs and third-party running programs. Generally speaking, the higher the CPU usage rate of the system, the more programs run in the mobile terminal; the lower the CPU usage rate of the system, the fewer programs run in the mobile terminal. The mobile terminal may obtain the CPU usage rate of the system according to a preset first time interval, and the preset first time interval may be a time interval set by a user, or may be a time interval obtained according to historical collection time.
移动终端获取系统CPU占用率的步骤可包括：移动终端按照预设的第一时间间隔采集系统CPU累计工作时长，获取连续两次采集的CPU累计工作时长中后一次CPU累计工作时长与前一次CPU累计工作时长的差值，上述差值即为系统CPU在预设的第一时间间隔内真正工作的时间，上述差值与预设的第一时间间隔的比值即在预设的第一时间间隔内系统CPU占用率。上述CPU累计工作时长为移动终端自启动到当前时刻CPU工作的总时长。上述预设的第一时间间隔可为5秒至20秒中任一时长，优选的，可为5秒。例如，移动终端每隔5秒采集一次系统CPU累计工作时长，若连续两次采集的CPU累计工作时长分别为60分03秒和60分04秒，则在这5秒的时间内系统CPU占用率为20％。The step for the mobile terminal to obtain the CPU usage rate of the system may include: the mobile terminal collects the cumulative working hours of the system CPU according to a preset first time interval, and obtains the difference between the cumulative working hours of the CPU in the last two consecutive collections and the cumulative working hours of the previous CPU. The difference between the cumulative working hours, the above difference is the real working time of the system CPU in the preset first time interval, the ratio of the above difference to the preset first time interval is the time in the preset first time interval CPU usage of the internal system. The cumulative working hours of the CPU above are the total working hours of the CPU from the start of the mobile terminal to the current moment. The aforementioned preset first time interval may be any length of time from 5 seconds to 20 seconds, preferably, it may be 5 seconds. For example, the mobile terminal collects the cumulative working hours of the system CPU every 5 seconds. If the cumulative working hours of the CPU collected twice in a row are 60 minutes 03 seconds and 60 minutes 04 seconds respectively, the system CPU usage during these 5 seconds 20%.
在Android系统中，可在/proc目录下读取系统CPU相关信息。其中，/proc目录下stat文件包含了系统CPU活动的所有信息，上述系统CPU活动的所有信息均为移动终端自启动到当前时刻CPU活动累计的时长。移动终端中CPU监控模块可定时读取/proc目录下系统CPU活动信息，再获取移动终端在采集时间内的系统CPU占用率。In the Android system, system CPU-related information can be read in the /proc directory. Among them, the stat file under the /proc directory contains all the information of the CPU activity of the system, and all the information of the CPU activity of the above system is the accumulated time of the CPU activity from the start of the mobile terminal to the current moment. The CPU monitoring module in the mobile terminal can regularly read the system CPU activity information in the /proc directory, and then obtain the system CPU usage rate of the mobile terminal within the collection time.
步骤204，若当前系统CPU占用率与相邻上一次系统CPU占用率的差值超过指定值，将当前系统CPU占用率作为第一CPU占用率。Step 204, if the difference between the current system CPU usage rate and the adjacent last system CPU usage rate exceeds a specified value, use the current system CPU usage rate as the first CPU usage rate.
移动终端在获取到当前系统CPU占用率后，会把当前系统CPU占用率与相邻上一次系统CPU占用率作差，获取系统CPU占用率差值。若上述系统CPU占用率差值超过指定值，则判定移动终端系统CPU占用率变化较大，移动终端内系统CPU占用率异常。一般情况下，上述指定值设定为正数，可为15％至20％任一数字，优选的可为20％。系统CPU占用率差值大于上述指定值，即移动终端系统CPU占用率突然增大，移动终端系统CPU占用率异常。将获取的当前系统CPU占用率作为第一CPU占用率，即异常CPU占用率。After obtaining the current system CPU usage rate, the mobile terminal will compare the current system CPU usage rate with the adjacent previous system CPU usage rate to obtain the system CPU usage rate difference. If the above-mentioned system CPU usage difference exceeds a specified value, it is determined that the mobile terminal system CPU usage rate changes greatly, and the system CPU usage rate in the mobile terminal is abnormal. Generally, the above specified value is set as a positive number, which can be any number from 15% to 20%, preferably 20%. The system CPU usage difference is greater than the specified value above, that is, the mobile terminal system CPU usage suddenly increases, and the mobile terminal system CPU usage is abnormal. The acquired current system CPU usage rate is used as the first CPU usage rate, that is, the abnormal CPU usage rate.
步骤206，若系统CPU占用率不小于第一CPU占用率的持续时长超过指定时长，获取各应用程序CPU占用率。Step 206 , if the system CPU usage rate is not less than the first CPU usage rate and the duration exceeds a specified duration, acquire the CPU usage rates of each application program.
在移动终端获取第一CPU占用率后，再次按照预设的第一时间间隔获取预设次数的移动终端中系统CPU占用率，并将获取的系统CPU占用率依次与第一CPU占用率作比较。若获取的系统CPU占用率均不小于第一CPU占用率，则系统CPU占用率不小于异常CPU占用率的持续时长超过指定时长，即移动终端中存在应用程序持续大量消耗CPU资源，获取移动终端中各应用程序的CPU占用率。上述预设的第一时间间隔可为5秒至30秒中任意时间，优选的，可为5秒。例如，移动终端连续两次采集的系统CPU占用率为20％和40％，系统CPU占用率差值大于指定值15％，则将系统CPU占用率为40％作为第一CPU占用率。按照预设的第一时间间隔每隔5秒采集一次系统CPU占用率，共采集4次系统CPU占用率，分别为42％、45％、47％、50％，上述4次系统CPU占用率均超过40％，即移动终端系统CPU占用率超过40％的持续时长达到20秒超过指定时长18秒，获取移动终端中各应用程序CPU占用率。After the mobile terminal acquires the first CPU occupancy rate, it acquires the system CPU occupancy rate of the mobile terminal for a preset number of times again according to the preset first time interval, and compares the acquired system CPU occupancy rate with the first CPU occupancy rate in sequence . If the acquired system CPU usage rates are not less than the first CPU usage rate, then the duration of the system CPU usage rate is not less than the abnormal CPU usage rate exceeds the specified duration, that is, there are applications in the mobile terminal that continue to consume a large amount of CPU resources, and obtain the mobile terminal The CPU usage of each application program in . The above preset first time interval may be any time between 5 seconds and 30 seconds, preferably, it may be 5 seconds. For example, if the system CPU occupancy rates collected by the mobile terminal are 20% and 40% for two consecutive times, and the difference between the system CPU occupancy rates is greater than a specified value of 15%, then the system CPU occupancy rate of 40% is taken as the first CPU occupancy rate. According to the preset first time interval, the CPU usage of the system is collected every 5 seconds. The CPU usage of the system is collected 4 times in total, which are 42%, 45%, 47%, and 50%. More than 40%, that is, the duration of the CPU usage of the mobile terminal system exceeding 40% reaches 20 seconds and exceeds the specified duration of 18 seconds to obtain the CPU usage of each application program in the mobile terminal.
移动终端获取各应用程序CPU占用率的步骤可包括：按照预设的第二时间间隔采集移动终端中正在运行的各个应用程序的占用CPU的累计时长，获取连续两次采集的应用程序的占用CPU的累计时长中后一次占用CPU的累计时长与前一次占用CPU的累计时长的差值，上述差值为应用程序在第二时间间隔内占用CPU的时间，上述差值与第二时间间隔的比值为在第二时间间隔应用程序CPU占用率。上述第一时间间隔和第二时间间隔可为相同值或不同值。The step for the mobile terminal to acquire the CPU occupancy rate of each application program may include: collecting the cumulative CPU usage time of each application program running in the mobile terminal according to a preset second time interval, and obtaining the CPU occupancy time of the application programs collected twice in a row. The difference between the accumulative duration of the last CPU occupation and the cumulative duration of the previous CPU occupation in the cumulative duration of , the above difference is the time that the application occupies the CPU in the second time interval, the ratio of the above difference to the second time interval CPU usage for the application during the second time interval. The above-mentioned first time interval and second time interval may be the same value or different values.
在Android系统中，/proc/pid目录下sats文件包含了应用程序对应的进程占用CPU的信息。上述应用程序对应的进程占用CPU的信息为应用程序自启动后占用CPU的累计时长。移动终端中CPU监控模块可定时读取/proc/pid目录下各应用程序占用CPU的累计时长，再获取应用程序在采集时间内应用程序CPU占用率。In the Android system, the sats file in the /proc/pid directory contains information about the CPU usage of the process corresponding to the application. The information about the CPU occupied by the process corresponding to the above application program is the accumulated time of the CPU occupied by the application program since it was started. The CPU monitoring module in the mobile terminal can regularly read the cumulative time of CPU usage of each application program in the /proc/pid directory, and then obtain the CPU usage rate of the application program within the collection time.
本发明实施例中CPU监测方法，按照预设的第一时间间隔采集系统CPU占用率，即移动终端中总CPU占用率，当检测到系统CPU占用率大幅度增大时且持续较长时间时，可判定移动终端中存在应用程序大量消耗CPU资源，则获取移动终端中当前运行的应用程序对应的应用程序CPU占用率。上述方法，在系统总CPU迅速增大时，能够及时获取应用程序对应的CPU占用率，有利于监控应用程序的CPU占用率，识别异常应用程序。In the CPU monitoring method in the embodiment of the present invention, the system CPU occupancy rate is collected according to the preset first time interval, that is, the total CPU occupancy rate in the mobile terminal, when it is detected that the system CPU occupancy rate increases significantly and lasts for a long time , it can be determined that there is an application program in the mobile terminal that consumes a large amount of CPU resources, and then the CPU usage rate of the application program corresponding to the application program currently running in the mobile terminal is acquired. The above method can timely obtain the CPU usage rate corresponding to the application program when the total CPU of the system increases rapidly, which is beneficial to monitor the CPU usage rate of the application program and identify abnormal application programs.
在一个实施例中，在获取各应用程序CPU占用率之前，上述CPU监测方法还包括：In one embodiment, before acquiring the CPU usage of each application program, the above CPU monitoring method further includes:
步骤302，查找上一次获取各应用程序CPU占用率的时刻。Step 302, look up the time when the CPU usage of each application program was acquired last time.
步骤304，若当前时刻与上一次获取各应用程序CPU占用率的时刻的时间差超过第一阈值，获取各应用程序CPU占用率。Step 304, if the time difference between the current time and the last time the CPU usage of each application program is obtained exceeds a first threshold, obtain the CPU usage of each application program.
移动终端在获取各应用程序对应的应用程序CPU占用率之前，会查找上一次获取各应用程序CPU占用率的时刻，获取当前时刻与上一次获取各应用程序CPU占用率时刻之间的时间差。若上述时间差超过预设的第一阈值，则获取应用程序CPU占用率。获取应用程序CPU占用率的步骤与步骤206中获取应用程序CPU占用率的步骤相同，在此不再赘述。若上述时间差未超过预设的第一阈值，则直接获取上一次采集的各应用程序CPU占用率作为当前各应用程序CPU占用率。上述第一阈值可为用户设定的值，也可为根据历史采集的各应用程序CPU占用率数据分析得到的数值，如30秒，1分钟等。Before obtaining the application CPU usage corresponding to each application, the mobile terminal will search for the last time the CPU usage of each application was obtained, and obtain the time difference between the current time and the last time the CPU usage of each application was obtained. If the above-mentioned time difference exceeds the preset first threshold, the CPU usage rate of the application program is obtained. The step of obtaining the CPU usage of the application program is the same as the step of obtaining the CPU usage of the application program in step 206, and will not be repeated here. If the above time difference does not exceed the preset first threshold, the CPU usage rate of each application program collected last time is directly acquired as the current CPU usage rate of each application program. The above-mentioned first threshold may be a value set by the user, or may be a value obtained by analyzing historically collected CPU usage data of each application program, such as 30 seconds, 1 minute, and so on.
移动终端中应用程序CPU占用率在短时间内不会发生变化，且获取各应用程序CPU占用率需要消耗一定的系统资源。本发明实施例中CPU监测方法，在接收到获取各应用程序对应的应用程序CPU占用率请求后，先获取当前时刻与上一次获取各应用程序对应的应用程序CPU占用率时刻的时间差，判断时间差与预设时长的关系，在时间差较短时，直接将上一次获取的各应用程序CPU占用率作为当前各应用程序CPU占用率，在时间差较长时，在重新获取各应用程序CPU占用率。既保证了获取个应用程序CPU占用率的准确性，有降低了系统功耗，节省了系统资源。The CPU usage rate of the application program in the mobile terminal does not change in a short period of time, and obtaining the CPU usage rate of each application program needs to consume certain system resources. In the CPU monitoring method in the embodiment of the present invention, after receiving the request for acquiring the CPU occupancy rate of the application program corresponding to each application program, first obtain the time difference between the current time and the time when the CPU occupancy rate of the application program corresponding to each application program was obtained last time, and determine the time difference The relationship with the preset time length, when the time difference is short, directly use the CPU usage rate of each application program obtained last time as the current CPU usage rate of each application program, and when the time difference is long, obtain the CPU usage rate of each application program again. It not only ensures the accuracy of obtaining the CPU usage rate of an application program, but also reduces system power consumption and saves system resources.
在一个实施例中，步骤202获取系统CPU占用率包括：In one embodiment, step 202 to obtain the system CPU usage includes:
(1)获取连续两次采集的系统CPU累计工作时长的差值作为第一差值。(1) Acquiring the difference between the accumulated working hours of the system CPU collected twice in a row as the first difference.
(2)根据第一差值和时间间隔获取系统CPU占用率。(2) Obtain the system CPU usage rate according to the first difference value and the time interval.
在Android系统中，可在/proc目录下读取系统CPU相关信息。其中，/proc目录下stat文件包含了系统CPU活动的所有信息，上述系统CPU活动的所有信息均为移动终端自启动到当前时刻CPU活动累计的时长。移动终端中CPU监控模块可定时读取/proc目录下系统CPU活动信息，再获取移动终端在采集时间内的系统CPU占用率。移动终端获取系统CPU占用率的步骤可包括：移动终端按照预设的第一时间间隔采集系统CPU累计工作时长，获取连续两次采集的CPU累计工作时长中后一次CPU累计工作时长与前一次CPU累计工作时长的差值，上述差值即为系统CPU在预设的第一时间间隔内真正工作的时间，上述差值与预设的第一时间间隔的比值即在预设的第一时间间隔内系统CPU占用率。上述CPU累计工作时长为移动终端自启动到当前时刻CPU工作的总时长。上述预设的第一时间间隔可为5秒至20秒中任一时长，优选的，可为5秒。In the Android system, system CPU-related information can be read in the /proc directory. Among them, the stat file under the /proc directory contains all the information of the CPU activity of the system, and all the information of the CPU activity of the above system is the accumulated time of the CPU activity from the start of the mobile terminal to the current moment. The CPU monitoring module in the mobile terminal can regularly read the system CPU activity information in the /proc directory, and then obtain the system CPU usage rate of the mobile terminal within the collection time. The step for the mobile terminal to obtain the CPU usage rate of the system may include: the mobile terminal collects the cumulative working hours of the system CPU according to a preset first time interval, and obtains the difference between the cumulative working hours of the CPU in the last two consecutive collections and the cumulative working hours of the previous CPU. The difference between the cumulative working hours, the above difference is the real working time of the system CPU in the preset first time interval, the ratio of the above difference to the preset first time interval is the time in the preset first time interval CPU usage of the internal system. The cumulative working hours of the CPU above are the total working hours of the CPU from the start of the mobile terminal to the current moment. The aforementioned preset first time interval may be any length of time from 5 seconds to 20 seconds, preferably, it may be 5 seconds.
在一个实施例中，上述CPU监测方法还包括：In one embodiment, the above-mentioned CPU monitoring method also includes:
步骤402，若检测到应用程序对应的CPU占用率超过第二阈值，检测应用程序是否满足预设规则。Step 402, if it is detected that the CPU usage rate corresponding to the application program exceeds the second threshold, check whether the application program satisfies a preset rule.
步骤404，若否，停止运行应用程序对应的进程。Step 404, if not, stop running the process corresponding to the application program.
移动终端在获取到各应用程序对应的CPU占用率后，依次比较各应用程序对应的CPU占用率是否超过预设的第二阈值，若超过预设的第二阈值，则表示应用程序CPU占用率过高，进一步检测上述应用程序是否满足预设规则。上述第二阈值可为用户设定的值，也可为根据历史获取的应用程序CPU占用率分析得到的值，如上述第二阈值可为20％。预设规则包括：系统白名单中应用程序、前台运行的应用程序、应用程序正在执行预设行为(包括下载文件、上传文件、应用程序更新等)、优先级较高的应用程序、播放音乐的应用程序等。上述预设规则可为用户设置的规则。当应用程序满足上述预设规则时，不对应用程序进行处理，如对用户设置的白名单中应用程序不进行处理、对用户设置的优先级前三的应用程序不进行处理。当应用程序不满足上述预设规则时，停止运行上述应用程序对应的进程。其中，停止运行上述应用程序对应的进程包括：关闭或挂起应用程序对应的进程等方式，其中，关闭应用程序对应的进程指的是终止(kill)应用程序对应的进程，挂起应用程序对应的进程指的是暂停应用程序对应的进程的运行，可将挂起的应用程序对应的进程加入等待队列中，当系统CPU占用率较低时，再恢复应用程序对应的进程的运行。After the mobile terminal obtains the CPU occupancy rate corresponding to each application program, it compares whether the CPU occupancy rate corresponding to each application program exceeds the preset second threshold in turn. If it exceeds the preset second threshold value, it means that the application program CPU occupancy rate If the value is too high, further check whether the above application meets the preset rules. The above-mentioned second threshold may be a value set by a user, or may be a value obtained by analyzing the CPU usage rate of an application obtained in history, for example, the above-mentioned second threshold may be 20%. Preset rules include: applications in the system whitelist, applications running in the foreground, applications that are performing preset behaviors (including downloading files, uploading files, application updates, etc.), applications with higher priority, applications that play music applications etc. The aforementioned preset rules may be rules set by the user. When the application meets the above preset rules, the application is not processed, for example, the application in the white list set by the user is not processed, and the application programs with the top three priorities set by the user are not processed. When the application program does not satisfy the above preset rule, stop running the process corresponding to the above application program. Wherein, stopping the process corresponding to the application above includes: closing or suspending the process corresponding to the application, etc., wherein closing the process corresponding to the application refers to terminating (killing) the process corresponding to the application, and suspending the process corresponding to the application The process refers to suspending the operation of the process corresponding to the application program. The process corresponding to the suspended application program can be added to the waiting queue. When the CPU usage of the system is low, the operation of the process corresponding to the application program can be resumed.
本发明实施例中CPU监测方法，在移动终端中应用程序CPU占用率较高时，检测应用程序是否为移动终端预设的不处理应用程序或用户设定的不处理应用程序。当不是不处理应用程序时，停止运行应用程序对应的进行，即对CPU占用率异常的应用程序进行查杀处理，避免了移动终端中异常应用程序大量耗费CPU资源，造成移动终端系统卡顿、发热等。其中，预设规则可以保证应用程序正常占用大量CPU资源的情况下，应用程序不被清理，提高了识别异常应用程序的精确度，查杀的异常应用程序更准确。In the CPU monitoring method in the embodiment of the present invention, when the CPU usage rate of the application program in the mobile terminal is high, it is detected whether the application program is a preset non-processing application program of the mobile terminal or a non-processing application program set by the user. When the application program is not not processed, stop running the application program correspondingly, that is, to check and kill the application program with abnormal CPU usage rate, so as to avoid the abnormal application program in the mobile terminal from consuming a large amount of CPU resources, causing the mobile terminal system to freeze, fever etc. Among them, the preset rules can ensure that the application program is not cleaned up when the application program normally occupies a large amount of CPU resources, which improves the accuracy of identifying abnormal application programs, and kills abnormal application programs more accurately.
在一个实施例中，上述CPU监测方法还包括：In one embodiment, the above-mentioned CPU monitoring method also includes:
步骤502，根据系统CPU占用率获取对应的CPU占用级别。In step 502, a corresponding CPU occupancy level is acquired according to the system CPU occupancy rate.
可预先划分多个CPU占用级别，每个占用级别可对应不同的占用率范围，例如，划分4个CPU占用级别，包括L1、L2、L3及L4，其中，L1占用级别对应的占用率范围为小于20％，L2占用级别对应的占用率范围为20％～40％，L3占用级别对应的占用率范围为40％～60％，L4占用级别对应的占用率范围为大于60％等，不限于此。移动终端按照预设的第一时间间隔采集系统CPU占用率，可确定采集的系统CPU占用率落入的占用率范围，并得到与该落入的占用率范围对应的CPU占用级别。例如，采集的系统CPU占用率为18％，则CPU占用级别为L1，系统CPU占用率为25％，则CPU占用级别为L2等。Multiple CPU occupancy levels can be divided in advance, and each occupancy level can correspond to a different occupancy rate range. For example, four CPU occupancy levels can be divided, including L1, L2, L3, and L4. Among them, the occupancy rate range corresponding to the L1 occupancy level is Less than 20%, the occupancy rate corresponding to the L2 occupancy level ranges from 20% to 40%, the occupancy rate corresponding to the L3 occupancy level ranges from 40% to 60%, and the occupancy rate corresponding to the L4 occupancy level ranges from more than 60%, etc., not limited to this. The mobile terminal collects the system CPU usage at a preset first time interval, determines the usage range that the collected system CPU usage falls into, and obtains the CPU usage level corresponding to the usage range. For example, if the collected system CPU usage rate is 18%, the CPU usage level is L1, and the system CPU usage rate is 25%, then the CPU usage level is L2, and so on.
步骤504，累计连续维持在占用级别的次数。Step 504, accumulating the number of times of continuous maintenance at the occupancy level.
移动终端可为每个CPU占用级别分配一个级别计数器，通过级别计数器记录CPU维持在对应的占用级别的连续次数，其中，CPU维持在某个占用级别，指的是CPU一直处于该占用级别或以上的占用级别，例如，CPU占用级别变化为L2占用级别、L3占用级别、L2占用级别，则可认为CPU维持在L2占用级别，连续次数为3。The mobile terminal can assign a level counter to each CPU occupancy level, and use the level counter to record the continuous number of times the CPU maintains the corresponding occupancy level, wherein, the CPU maintains a certain occupancy level, which means that the CPU has been at the occupancy level or above For example, if the CPU occupancy level changes to L2 occupancy level, L3 occupancy level, and L2 occupancy level, it can be considered that the CPU maintains the L2 occupancy level, and the number of consecutive times is 3.
在一个实施例中，移动终端按照预设的第一时间间隔采集系统CPU占用率，并确定CPU占用级别，可分别在该占用级别及以下的占用级别对应的级别计数器中加1，并将其他占用级别的级别计数器清零。例如，本次的CPU占用级别为L3，则将L1、L2及L3的级别计数器分别加1，L4的级别计数器清零，下一次的CPU占用级别为L2，则将L1、L2的级别计数器分别加1，L3、L4的级别计数器清零。In one embodiment, the mobile terminal collects the CPU occupancy rate of the system according to the preset first time interval, and determines the CPU occupancy level, and can respectively add 1 to the level counter corresponding to the occupancy level and the occupancy level below the occupancy level, and set other The level counter of the occupied level is cleared. For example, if the current CPU usage level is L3, the level counters of L1, L2, and L3 will be incremented by 1, and the level counter of L4 will be cleared. The next time the CPU usage level is L2, the level counters of L1 and L2 will be respectively Add 1, and the level counters of L3 and L4 are cleared.
在一个实施例中，可划分占用级别的类型，其中，类型可包括为空闲级别及繁忙级别，例如，将L1占用级别作为空闲级别，将L2、L3、L4占用级别作为繁忙级别，分别代表不同的繁忙程度。移动终端每隔预设的第一时间间隔采集系统CPU占用率，并计算CPU占用级别，可先确定对应的类型，再分别在该占用级别及以下的属于同一类型的占用级别对应的级别计数器中加1，并将其他占用级别的级别计数器清零。例如，本次的CPU占用级别为L1，属于空闲级别，则将L1的级别计数器加1，L2、L3及L4的级别计数器清零，下一次的CPU占用级别为L3，属于繁忙级别，则将L3以及同属于繁忙级别的L2的级别计数器分别加1，L1、L4的级别计数器清零。In one embodiment, the types of occupancy levels can be divided, wherein the types can include idle levels and busy levels, for example, the L1 occupancy level is used as the idle level, and the L2, L3, and L4 occupancy levels are used as the busy level, respectively representing different of busyness. The mobile terminal collects the CPU occupancy rate of the system every preset first time interval, and calculates the CPU occupancy level. The corresponding type can be determined first, and then the occupancy level and the occupancy level below the occupancy level of the same type correspond to the level counters. Increment by 1 and clear level counters for other occupied levels. For example, if the current CPU occupation level is L1, which belongs to the idle level, the level counter of L1 will be incremented by 1, and the level counters of L2, L3, and L4 will be cleared. The next time the CPU occupation level is L3, which belongs to the busy level, then the The level counters of L3 and L2 which belong to the same busy level are incremented by 1, and the level counters of L1 and L4 are cleared to zero.
步骤506，当次数达到占用级别对应的第三阈值时，确定与占用级别对应的繁忙程度。Step 506, when the number of times reaches the third threshold corresponding to the occupation level, determine the busyness corresponding to the occupation level.
可为每个CPU占用级别设定对应的第三阈值，该第三阈值可用于判断移动终端的CPU是否维持在对应占用级别的工作状态中。移动终端通过级别计数器累计CPU连续维持在各个占用级别的次数，当CPU连续维持在占用级别的次数达到与该占用级别对应的第三阈值时，则可认定CPU稳定在该占用级别的工作状态中。例如，对L1、L2、L3及L4，分别设定一个对应的第三阈值为c1、c2、c3及c4，当CPU连续维持在L1级别的次数达到c1，则认定CPU稳定在L1的工作状态中。进一步地，各占用级别对应的第三阈值，可随着占用级别的增大而减小，例如，L1、L2、L3及L4对应的第三阈值为c1、c2、c3及c4，其中，c1>c2>c3>c4，比如，c1为5次，c2为4次，c3为3次，c4为2次等，但不限于此。在一个实施例中，若同时存在多个连续维持的次数达到对应的第三阈值的占用级别，则选取最高级别的占用级别作为CPU稳定的工作状态。A corresponding third threshold can be set for each CPU occupancy level, and the third threshold can be used to determine whether the CPU of the mobile terminal is maintained in the working state of the corresponding occupancy level. The mobile terminal uses the level counter to accumulate the number of times the CPU is continuously maintained at each occupancy level. When the number of times the CPU is continuously maintained at the occupancy level reaches the third threshold corresponding to the occupancy level, it can be determined that the CPU is stable in the working state of the occupancy level. . For example, for L1, L2, L3, and L4, set a corresponding third threshold value to c1, c2, c3, and c4 respectively. When the number of times the CPU maintains the level of L1 reaches c1, it is determined that the CPU is stable in the working state of L1. middle. Further, the third threshold corresponding to each occupancy level may decrease as the occupancy level increases, for example, the third thresholds corresponding to L1, L2, L3, and L4 are c1, c2, c3, and c4, where c1 >c2>c3>c4, for example, c1 is 5 times, c2 is 4 times, c3 is 3 times, c4 is 2 times, etc., but not limited to this. In one embodiment, if there are multiple occupancy levels whose consecutive maintenance times reach the corresponding third threshold, the highest occupancy level is selected as the stable working state of the CPU.
本发明实施例中CPU监测方法，对CPU占用率设定不同的占用级别，根据维持在占用级别的次数确定移动终端的繁忙程度，有利于根据移动终端的繁忙程序对应用程序进行不同的处理，如在占用级别较高，系统较繁忙时，直接关闭异常应用程序对应的进程；在占用级别较低，系统较空闲时，挂起异常应用程序对应的进程，提高了处理异常应用程序的灵活性。In the CPU monitoring method in the embodiment of the present invention, different occupancy levels are set for the CPU occupancy rate, and the busyness of the mobile terminal is determined according to the number of times maintained at the occupancy level, which is conducive to different processing of the application program according to the busy program of the mobile terminal, For example, when the occupation level is high and the system is busy, the process corresponding to the abnormal application is directly closed; when the occupation level is low and the system is relatively idle, the process corresponding to the abnormal application is suspended, which improves the flexibility of handling abnormal applications .
