DETAILED DESCRIPTION

[0020] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0022] In the following description, a lot of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0023] Combine the following Figures 1 to 7 , the application CPU occupancy monitoring method, system and electronic device provided by the present invention are explained.

[0024] See also Figure 1 , Figure 1 A flowchart of a method for monitoring application CPU occupancy provided by an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes: S110: Read the image file in the target disk to obtain the target image, wherein the target image includes a target QR code, and the target QR code is generated according to the CPU exceeding information of the application, wherein the CPU exceeding information includes: the application package name of the application, the actual CPU usage of the application, and the CPU usage target value.

[0025] S120: Obtain the CPU exceeding standard information of the application by identifying the target two-dimensional code.

[0026] S130: If the application package name in the CPU exceeding standard information is the application package name identified for the first time, a CPU exceeding standard Bug is created and reported according to the CPU exceeding standard information.

[0027] It should be noted that the above method can better monitor the CPU usage exceeding the standard of the application, so that relevant personnel can optimize the performance of the application in a timely manner according to the CPU usage exceeding the standard.

[0028] It should also be noted that the application CPU occupancy monitoring method in this embodiment is applied to the field of intelligent driving technology. In modern automotive electronic systems, vehicle-mounted applications have gradually become an important part of intelligent driving, such as applications in Android systems. Each vehicle-mounted application will occupy part of the CPU (central processing unit) resources when it is running. Since the CPU resources of the vehicle-mounted system are limited, when multiple vehicle-mounted applications compete for limited CPU resources, it may cause high load and other situations, resulting in reduced fluency and performance of the vehicle-mounted system, such as stuck and frozen screen in the vehicle-mounted system. Due to the lack of a monitoring method for the excessive CPU occupancy of vehicle-mounted applications, it is impossible to better monitor the excessive CPU occupancy of vehicle-mounted applications, which makes it inconvenient to optimize the performance of vehicle-mounted applications in a timely manner. Therefore, the above-mentioned application CPU occupancy monitoring method is adopted in this embodiment to solve the above problems.

[0029] In some embodiments, when the CPU occupancy monitoring method of the application in the above embodiment is used to monitor the CPU occupancy exceeding standard of the vehicle-mounted application in the vehicle's operating system, first, the image file in the target disk (the target disk can be a vehicle-mounted disk) is read to obtain the target image, and the target image includes a target QR code, and the target QR code is generated according to the CPU exceeding standard information of the application (vehicle-mounted application); secondly, the CPU exceeding standard information of the application is obtained by identifying the target QR code; finally, if the application package name in the CPU exceeding standard information is the application package name identified for the first time, then according to the CPU exceeding standard information, a CPU exceeding standard Bug is created and reported. It can be seen that by adopting the CPU occupancy monitoring method of the application in the above embodiment, real-time monitoring of the CPU occupancy exceeding standard of the application in the vehicle's operating system can be better achieved.

[0030] The application CPU occupancy monitoring method in the above embodiment is applicable not only to the field of intelligent driving technology, but also to multiple technical fields such as game development and smart home. The following takes the field of game development as an example to exemplify the above application CPU occupancy monitoring method.

[0031] Today's game platforms usually include multiple game applications. During the game development process, it is particularly important to monitor the CPU usage of each game application. Assuming that the application CPU usage monitoring method in the above embodiment is used to monitor the CPU usage of each application in the game platform, first, the image file in the target disk (the target disk can be a disk storing games) is read to obtain the target image, and the target image includes a target QR code, which is generated according to the CPU usage information of each application in the game platform; secondly, the CPU usage information of the application is obtained by identifying the target QR code; finally, if the application package name in the CPU usage information is the first recognized application package name, then according to the CPU usage information, a CPU usage bug is created and reported.

[0032] Similarly, the application CPU occupancy monitoring method in the above embodiment can also be applied to fields such as smart home, which will not be described in detail here.

[0033] The following is a further explanation of the CPU occupancy monitoring method in the context of intelligent driving.

[0034] For the sake of convenience of explanation, the operations of reading the image file, identifying the target QR code, and creating the CPU exceeding the standard bug in the above embodiment are collectively referred to as the bug reporting operation, that is, the bug reporting operation includes the operations of reading the image file, identifying the target QR code, and creating and reporting the CPU exceeding the standard bug. It can be understood that the bug reporting operation and the image file generation operation can be performed on the same device end or on different device ends.

[0035] In order to better apply to the field of intelligent driving technology and to reduce the operating load of the vehicle's operating system, in this embodiment, the image file generation operation is performed by the vehicle's operating system (the CPU occupancy monitoring module set in the operating system), and the operating system (the CPU occupancy monitoring module set in the operating system) saves the generated image file to the target disk (such as the vehicle computer disk). The bug reporting operation is performed by an external device to achieve asynchronous execution of the bug reporting operation and the image file generation operation, thereby improving the flexibility and controllability of the bug reporting operation and the image file generation operation. In other words, the image file in the above embodiment is generated by the CPU occupancy monitoring module preset in the vehicle operating system, and the bug reporting operation is performed by an external device other than the operating system.

[0036] It should be noted that the operating system of the vehicle in the above embodiment is the Android system, which belongs to the vehicle system, and the vehicle system also includes the QNX system (a real-time operating system based on a microkernel architecture). The QNX system is the main system, which is mainly responsible for functions such as instrument applications, including applications such as instrument HMI (human-machine interface) applications, boot animation applications, and 360 panoramic image applications. The Android system is the secondary system, which is mainly responsible for functions such as central control entertainment information applications, including applications such as vehicle settings, Bluetooth phones, multimedia, driving recorders, air conditioning settings, voice, and virtual images.

[0037] The following is an explanation of how to generate image files.

[0038] In some embodiments, the CPU occupancy monitoring module generates the image file including: 1. Get the actual CPU usage of the application.

[0039] It should be noted that the application in this embodiment is an in-vehicle application. The actual CPU usage of one or more applications may be obtained in the above steps, that is, the actual CPU usage of a specified application may be obtained, and the specified application may be one or more, or the actual CPU usage of all applications in the operating system may be obtained. In order to better monitor the CPU occupancy of each application in the operating system, the actual CPU usage of all applications in the operating system is obtained in this embodiment, and subsequent comparison and monitoring are performed.

[0040] 2. Compare the actual CPU usage with the corresponding CPU usage target value to determine whether the CPU usage of the application exceeds the standard or is normal. The CPU usage target value is a preset value, and the CPU usage target value corresponds to the application package name one by one.

[0041] The CPU usage target value is read from a preset target value configuration file, and the target value configuration file includes a one-to-one corresponding application package name and a CPU usage target value. The application package name is a unique identifier of the application.

[0042] It should be noted that by presetting the target value configuration file, it is easy to read the target value of the CPU usage of the application, so as to facilitate the subsequent CPU occupancy comparison. In addition, by comparing the actual CPU usage with the corresponding CPU usage target value, it is easy to determine whether the CPU usage of the application exceeds the standard. Specifically, if the actual CPU usage is greater than the corresponding CPU usage target value, it is determined that the CPU usage of the current application exceeds the standard; if the actual CPU usage is less than or equal to the corresponding CPU usage target value, it is determined that the CPU usage of the current application is normal.

[0043] 3. If the CPU usage of the application exceeds the limit, the CPU exceeding limit information is displayed on a preset display screen, and a QR code is generated based on the CPU exceeding limit information, and the QR code is displayed on the display screen.

[0044] It should be noted that by generating a QR code based on the CPU over-limit information and displaying the QR code on the display screen, the subsequently captured picture contains the QR code, thereby facilitating subsequent QR code recognition. It should be mentioned that compared with the method of recognizing text information in the picture, the method of recognizing the QR code is not only simpler and faster, but also more accurate and is not affected by screen brightness, clarity, etc.

[0045] 4. Taking a screenshot of the display screen to obtain a first screenshot image, and determining the first screenshot image as the image file.

[0046] In some embodiments, before obtaining the actual CPU usage of the application, the CPU occupancy monitoring module further includes: determining whether the CPU monitoring function is turned on, wherein determining whether the CPU monitoring function is turned on includes: 1. Monitor the attribute value of the CPU monitoring switch. The CPU monitoring switch is a preset system attribute. The attribute value of the CPU monitoring switch changes with the on / off state of the CPU monitoring switch. The on / off state of the CPU monitoring switch is set manually.

[0047] It should be noted that after the operating system (Android system) is started, the AMS (ActivityManager Service) service of the Android system is started, and the CPU usage monitoring module built into the AMS service is started. In order to determine whether CPU monitoring is required, the CPU usage monitoring module needs to obtain the on / off status of the CPU monitoring function, so that when it is determined that the CPU monitoring function is turned on, subsequent file reading (reading the target value configuration file) and obtaining the actual CPU usage rate of the application in the operating system are performed. This step greatly improves the controllability of the entire application CPU usage monitoring method.

[0048] Specifically, a user (tester or developer, etc.) can turn on or off the CPU monitoring switch in the engineering mode application of the operating system (Android system). When the user turns on the CPU monitoring switch, the engineering mode application sets the attribute value of the CPU monitoring switch to a preset first attribute value. Conversely, when the user turns off the CPU monitoring switch, the engineering mode application sets the attribute value of the CPU monitoring switch to a preset second attribute value. The first attribute value is different from the second attribute value.

[0049] It should also be noted that, in this embodiment, a pre-registered listener is used to monitor the attribute value of the CPU monitoring switch.

[0050] 2. If the attribute value of the CPU monitoring switch is detected to be a preset first attribute value, it is determined that the CPU monitoring function is turned on. If it is determined that the CPU monitoring function is turned on, the actual CPU usage rate of the application is obtained.

[0051] 3. If it is detected that the attribute value of the CPU monitoring switch is a preset second attribute value, it is determined that the CPU monitoring function is turned off.

[0052] It should be noted that the first attribute value may be True, etc., and the second attribute value may be False, etc.

[0053] In addition to using the listener to monitor the attribute value of the CPU monitoring switch, in some embodiments, the following is also included: 1. Using the monitor, monitor the change of the attribute value of the CPU monitoring switch.

[0054] 2. If it is monitored that the attribute value of the CPU monitoring switch changes from the first attribute value to the second attribute value, the CPU monitoring function is turned off.

[0055] 3. If it is monitored that the attribute value of the CPU monitoring switch changes from the second attribute value to the first attribute value, the CPU monitoring function is turned on.

[0056] It should be noted that by using a listener to monitor changes in the attribute value of the CPU monitoring switch, the CPU monitoring function can be turned on and off at any time.

[0057] In some embodiments, before obtaining the actual CPU usage of the application, the method further includes: reading a preset target value configuration file to obtain a CPU usage target value of the application, wherein the step of reading the preset target value configuration file includes: The target value configuration file pre-burned to the target directory of the target disk is read to obtain structure data, wherein the structure data includes: an application package name and a CPU usage target value, and the application package name and the CPU usage target value correspond one to one.

[0058] It should be noted that by parsing the target value configuration file into the above structured data, it is possible to directly obtain the memory usage target value of the corresponding application package name and perform comparison in the subsequent comparison process.

[0059] It should also be noted that the target value configuration file is pre-configured with information such as the application package name, the CPU usage target value, and the system to which the application belongs. The CPU usage target value corresponding to each application package name in the target value configuration file is a preset empirical value, such as the CPU usage target value of the vehicle setting application is 70%, the CPU usage target value of the Bluetooth phone application is 20%, and the CPU usage target value of the driving recorder is 100%.

[0060] It should be mentioned that this embodiment adopts the vCPU (virtual central processing unit) method to divide the CPU of the vehicle system into multiple vCPUs. Assuming that there are currently 8 vCPUs (8 cores), and the operating system (Android system) can occupy 6 cores, the proportion of available CPU resources is 600%.

[0061] It is also worth mentioning that by setting the corresponding CPU usage target value for each application in the target value configuration file, the CPU usage upper limit of each application can be clearly defined, thereby facilitating subsequent monitoring of the excessive CPU usage of in-vehicle applications.

[0062] Figure 2 This is a flow chart of presetting a target value configuration file (pre-burning the target value configuration file to a specified directory of a target disk) in a method for monitoring application CPU usage provided in an embodiment of the present invention. Please refer to Figure 2 First, write the target value configuration file in the operating system (Android system) source code. Secondly, use the preset compilation tools, such as Jenkins (an open source automation server), etc. to compile and package the system source code. The compiled product is the system flashing package. Burn the system flashing package to the target directory of the target disk of the vehicle system to complete the preset target value configuration file. By burning the target value configuration file to the target directory of the above-mentioned target disk, it is convenient to read files later and improve the file reading efficiency. It should be mentioned that the system source code also includes product.mk (product build configuration file) and so on.

[0063] In some embodiments, it also includes: According to a preset event sending frequency, Monkey events are regularly sent to the operating system. The Monkey events are randomly generated user input events. The user input events are used to perform random operations on the interface of the application in the operating system.

[0064] It should be noted that the event sending frequency can be set according to actual conditions, such as 450 milliseconds / time. User input events include random clicks, slides, scrolls, long presses, and text input. By regularly sending Monkey events to the operating system, it is possible to simulate real events, thereby fully covering the operating logic of each application and fully exposing the CPU usage of each application, so as to facilitate early monitoring of the CPU usage of the application and handle it as soon as possible.

[0065] In some embodiments, obtaining the actual CPU usage of the application includes: 1. Obtain CPU usage information, where the CPU usage information includes: an initial CPU usage rate of the application process and an application package name of the application process.

[0066] It should be noted that the CPU usage information corresponds to the application process in the operating system one by one, that is, each application process corresponds to one piece of CPU usage information, and each application corresponds to one or more application processes.

[0067] In some embodiments, the CPU occupancy information is obtained using a preset process monitor (top tool).

[0068] 2. If there are application processes with the same application package name, the initial CPU usage rates of the application processes with the same application package name are summed to obtain the actual CPU usage rate of the application corresponding to the current application package name.

[0069] It should be noted that if the application package names in the CPU occupancy information are the same, it means that the application corresponding to the application package name is a multi-process application. Therefore, the initial CPU usage rates of the application package names with the same name are summed to obtain the actual CPU usage rate of the application corresponding to the current application package name. If the application package names of the remaining CPU occupancy information are different, the vehicle application corresponding to the remaining CPU occupancy information is a single-process application. Therefore, the initial CPU usage rate in the remaining CPU occupancy information is the actual CPU usage rate of the corresponding vehicle application.

[0070] 3. If the application package names in the CPU occupancy information are all different, determine the in-vehicle application to which the initial CPU usage belongs according to the application package names in the CPU occupancy information, and determine the initial CPU usage as the actual CPU usage of the corresponding in-vehicle application.

[0071] It should be noted that if the application package names in all the CPU occupancy information are different, it means that the applications of the operating system are all single-process applications, so the initial CPU usage rate in the CPU occupancy information is directly determined as the actual CPU usage rate of the corresponding vehicle-mounted application. It should be mentioned that the applications in the vehicle-mounted system are basically single-process applications, and the above embodiment can better meet the CPU occupancy monitoring needs of the vehicle-mounted system. In addition, even if the vehicle-mounted system includes multi-process applications, the above embodiment can better monitor the CPU occupancy or exceeding conditions of multi-process applications, and the feasibility is strong.

[0072] In some embodiments, obtaining the actual CPU usage of the application includes: obtaining the actual CPU usage of the application according to the execution frequency, wherein determining the execution frequency includes: 1. Get the system CPU idle rate.

[0073] It should be noted that the system CPU idle rate refers to the CPU idle rate of the vehicle's operating system. The system CPU idle rate can be obtained simultaneously with the CPU occupancy information, that is, the CPU occupancy information and the system CPU idle rate are obtained simultaneously using the process monitor. The system CPU idle rate determines the execution frequency of obtaining the actual CPU usage rate of the application later.

[0074] 2. If the system CPU idle rate is greater than or equal to a preset idle rate threshold, the execution frequency is determined as a preset first frequency.

[0075] 3. If the system CPU idle rate is less than the idle rate threshold, the execution frequency is determined to be a preset second frequency, where the second frequency is higher than the first frequency; It should be noted that the first frequency may be 2 times / minute, etc., and the second frequency may be 12 times / minute, etc. The CPU idle rate may be 100% (the proportion of available CPU resources is 600%), etc.

[0076] It should also be noted that if the system CPU idle rate is less than the preset idle rate threshold, it means that the current CPU available resources of the operating system are relatively small and the CPU usage of each application is seriously exceeded. Therefore, the execution frequency is adjusted from the lower first frequency to the higher second frequency until the system CPU idle rate is greater than or equal to the idle rate threshold, thereby achieving timely follow-up and accurate monitoring of the application's CPU usage exceeding the standard.

[0077] In some embodiments, generating the image file further includes: 1. When it is detected that the system CPU idle rate is less than the idle rate threshold, the currently acquired CPU occupancy information is displayed on the display screen; the CPU occupancy information includes: the initial CPU usage rate of the application process, the application package name of the application process, and the system CPU idle rate.

[0078] 2. According to the CPU occupancy information, determine the application whose CPU occupancy exceeds the limit to obtain CPU excess information.

[0079] 3. Generate a QR code based on the CPU exceeding standard information, and display the QR code on the display screen.

[0080] 4. Taking a screenshot of the display screen to obtain a second screenshot image, and determining the second screenshot image as the image file.

[0081] It should be noted that if the system CPU idle rate is detected to be less than the idle rate threshold, it means that the CPU usage of each application exceeds the standard seriously, so the CPU usage information is displayed on the display screen for identification by relevant personnel. According to the CPU usage information, the application with excessive CPU usage can be determined, and then the CPU usage information is obtained. A QR code is generated according to the CPU usage information, the QR code is displayed, and a screenshot of the display screen is taken.

[0082] It should be mentioned that, according to the CPU over-limit information, the steps of generating a QR code include: The CPU over-limit information and the current time are encapsulated into a string to obtain a target string, such as a json (a data exchange format) string, etc.; a preset QR code generation tool, such as zxing (a QR code scanner), etc. is used to convert the target string into a QR code.

[0083] It is also worth mentioning that the memory overload information can be displayed in a green screen with red text or other display methods to facilitate identification by relevant personnel. In addition, the above-mentioned image files are stored in a specified directory of the target disk.

[0084] In some embodiments, the picture file is named with the current time and / or serial number; the step of reading the picture file in the target disk to obtain the target picture includes: 1. Read the image files in the specified directory of the target disk according to the preset reading frequency.

[0085] It should be noted that the reading frequency can be set according to actual needs, such as 30 seconds / time.

[0086] 2. According to the names of the various picture files in the designated directory, determine whether the picture file is a newly generated picture file or a historical picture file.

[0087] For example: according to the time or serial number in the name of each image file, it is identified whether the current image file is a newly generated image file or a historical image file. The historical image file is an image file that has been identified, and the new image file is an image file that has not been identified.

[0088] 3. If the picture file is a newly generated picture file, the current picture file is determined as the target picture.

[0089] It should be noted that, through the above steps, it is possible to better monitor the CPU usage or over-limit situation of each application in the operating system.

When the CPU exceeding standard bug is created, the associated information of the CPU exceeding standard bug is recorded in a preset target list, and the associated information includes: application package name, actual CPU usage rate, and a link to the CPU exceeding standard bug.

[0091] It should be noted that, if the application package name in the CPU exceeding standard information does not exist in the target list, it means that the CPU exceeding standard information is the CPU exceeding standard information identified for the first time.

[0092] 2. If the application package name in the CPU exceeding standard information already exists in the target list, it is determined that the application that currently exceeds the CPU usage already has a report record, and the actual CPU usage rate in the current CPU exceeding standard information is compared with the actual CPU usage rate of the corresponding application in the target list; if the actual CPU usage rate in the current CPU exceeding standard information is greater than the actual CPU usage rate of the corresponding application in the target list, the target list and the corresponding reported CPU exceeding standard bug are updated. If the actual CPU usage rate in the current CPU exceeding standard information is greater than the actual CPU usage rate of the corresponding application in the target list, the currently identified CPU exceeding standard information is ignored.

[0093] It should be noted that through the above steps, accurate reporting of CPU over-limit bugs can be achieved, avoiding excessive reporting of data and causing redundancy.

[0096] 2. Send the CPU exceeding standard Bug to the target address.

[0097] It should be noted that, through the above steps, after reporting the CPU exceeding standard bug, the CPU exceeding standard bug can be automatically sent to the corresponding person in charge, so that the relevant person in charge can carry out bug repair and optimization in time.
