The data display method 200 can be applied to the vehicle-mounted processor 101 shown in FIG1 . In this embodiment, the data display method 200 can include the following steps:
步骤201，获取车载系统的目标器件在预设时间段内的使用数据。Step 201 : obtaining usage data of a target component of a vehicle-mounted system within a preset time period.
在本实施例中，执行主体(如图1中所示的车载处理器101)响应于接收到用户输入的资源占用情况的查询指令获取车载系统的目标器件在预设时间段内的使用数据。替代地，也可通过设置信息采集频率，使执行主体根据所设置的信息采集频率定期(如设置采集频率为1s)获取车载系统的目标器件在预设时间段内的使用数据。In this embodiment, the execution subject (such as the vehicle-mounted processor 101 shown in FIG1 ) obtains the usage data of the target device of the vehicle-mounted system within a preset time period in response to receiving the query instruction of the resource occupancy status input by the user. Alternatively, the information collection frequency can be set so that the execution subject obtains the usage data of the target device of the vehicle-mounted system within a preset time period according to the set information collection frequency (such as setting the collection frequency to 1s).
车载系统的目标器件可以包括CPU和内存中的至少一项。The target device of the in-vehicle system may include at least one of a CPU and a memory.
这里，预设时间段可根据经验、实际需求进行设定，例如，从当前时刻的前5分钟、前10分钟、前20分钟至当前时刻等，本公开对此不作限定。Here, the preset time period can be set according to experience and actual needs, for example, from 5 minutes, 10 minutes, 20 minutes before the current moment to the current moment, etc., and the present disclosure does not limit this.
执行主体可首先通过内置传感器和接口采集目标器件的使用数据，并对所采集到的目标器件的使用数据进行读取。读取方式可以包括但不限于运行ADB(Android DebugBridge，安卓调试桥)进行读取、基于proc文件系统进行读取、基于sys文件系统进行读取、基于日志文件进行读取等。The execution subject may first collect the usage data of the target device through the built-in sensor and interface, and read the collected usage data of the target device. The reading method may include but is not limited to running ADB (Android Debug Bridge) to read, reading based on the proc file system, reading based on the sys file system, reading based on the log file, etc.
ADB是android sdk里的一个工具，利用该工具可以直接操作管理android模拟器或者真实的android设备。它的主要功能有：运行设备的shell(命令行)、计算机和设备之间上传/下载文件等。ADB is a tool in the Android SDK that can be used to directly operate and manage the Android emulator or a real Android device. Its main functions include: running the device's shell (command line), uploading/downloading files between the computer and the device, etc.
这里，运行设备的shell(命令行)，即运行adb shell命令以读取数据，adb shell命令可以包括多种，例如，“adb shell dumpsys cpuinfo”命令、“adb shell procrank”命令等。作为示例，“adb shell dumpsys cpuinfo”命令用于读取当前系统中所有进程的CPU使用率，“adb shell procrank”命令用于读取当前系统的所有进程的内存使用情况。Here, the shell (command line) of the device is run, that is, the adb shell command is run to read the data. The adb shell command may include multiple types, for example, the "adb shell dumpsys cpuinfo" command, the "adb shell procrank" command, etc. As an example, the "adb shell dumpsys cpuinfo" command is used to read the CPU usage of all processes in the current system, and the "adb shell procrank" command is used to read the memory usage of all processes in the current system.
proc文件系统是一个伪文件系统，它只存在内存当中，而不占用外存空间。它以文件系统的方式为内核与进程提供通信的接口。用户和应用程序可以通过/proc得到系统的信息，并可以改变内核的某些参数。由于系统的信息(如进程)是动态改变的，所以用户或应用程序读取/proc目录中的文件时，proc文件系统是动态从系统内核读出所需信息并提交的。The proc file system is a pseudo file system that exists only in memory and does not occupy external memory space. It provides a communication interface between the kernel and the process in the form of a file system. Users and applications can obtain system information through /proc and can change certain parameters of the kernel. Since system information (such as processes) changes dynamically, when users or applications read files in the /proc directory, the proc file system dynamically reads the required information from the system kernel and submits it.
这里，/proc目录下的文件可以包括多种，例如，“/proc/stat”文件、“/proc/cpuinfo”文件等。“/proc/stat”文件包含了当前系统中的CPU时间、空闲时间、用户态时间和内核态时间等信息，“/proc/cpuinfo”文件包含了CPU架构、型号、频率和缓存等信息。Here, the files under the /proc directory may include multiple types, for example, the "/proc/stat" file, the "/proc/cpuinfo" file, etc. The "/proc/stat" file contains information such as the CPU time, idle time, user state time, and kernel state time in the current system, and the "/proc/cpuinfo" file contains information such as the CPU architecture, model, frequency, and cache.
sys文件系统是一种伪文件系统，用于将系统中的设备组织成层次结构，并向用户模式程序提供详细的内核数据结构信息。用户和应用程序可以通过/sys得到内核数据结构信息。The sys file system is a pseudo file system that organizes the devices in the system into a hierarchical structure and provides detailed kernel data structure information to user mode programs. Users and applications can obtain kernel data structure information through /sys.

The execution subject can use the "adb shell cat/proc/stat" command or the "/proc/stat" file to read the CPU time, idle time, user state time, and kernel state time in the current system. The execution subject can use the "/proc/cpuinfo" file to read information such as the CPU architecture, model, frequency, and cache. The execution subject can use the "/sys/devices/system/cpu/" file to read the hardware information about the CPU, such as the number of CPU cores, CPU frequency, and power management.
对于内存，执行主体可通过使用“adb shell dumpsys meminfo”命令，读取当前系统的进程的内存使用情况、内存分配情况、缓存使用情况等信息。执行主体可通过使用“adbshell procrank”命令，读取当前系统的所有进程的内存使用情况，包括：进程名、进程ID、进程的私有和共享内存等。执行主体可通过使用“adb shell cat/proc/meminfo”命令或“/proc/meminfo”文件，读取系统的内存信息，包括总内存大小、空闲内存大小、缓存大小等。执行主体可通过“/proc/[pid]/status”文件，读取指定进程的内存信息，包括进程的虚拟内存、物理内存、共享内存等。执行主体可通过“/proc/[pid]/smaps”文件，读取指定进程的内存映射信息，包括进程的堆、栈、动态链接库等内存映射信息。For memory, the execution subject can use the "adb shell dumpsys meminfo" command to read the memory usage, memory allocation, cache usage and other information of the current system process. The execution subject can use the "adbshell procrank" command to read the memory usage of all processes in the current system, including: process name, process ID, process private and shared memory, etc. The execution subject can use the "adb shell cat/proc/meminfo" command or the "/proc/meminfo" file to read the system's memory information, including total memory size, free memory size, cache size, etc. The execution subject can use the "/proc/[pid]/status" file to read the memory information of the specified process, including the process's virtual memory, physical memory, shared memory, etc. The execution subject can use the "/proc/[pid]/smaps" file to read the memory mapping information of the specified process, including the process's heap, stack, dynamic link library and other memory mapping information.
进一步地，车载系统的目标器件在预设时间段内的使用数据可以包括第一类型数据和第二类型数据，其中，第一类型数据指示车控数据，即与车辆控制相关联的功能(例如，车锁、车窗、驾驶、泊车等)对应的目标器件的使用数据，第二类型数据指示信息娱乐数据，即信息娱乐功能(例如，天气、音乐、日历、电台等等)对应的目标器件的使用数据。Furthermore, usage data of the target device of the vehicle-mounted system within a preset time period may include first type data and second type data, wherein the first type data indicates vehicle control data, i.e., usage data of the target device corresponding to functions associated with vehicle control (for example, locks, windows, driving, parking, etc.), and the second type data indicates infotainment data, i.e., usage data of the target device corresponding to infotainment functions (for example, weather, music, calendar, radio, etc.).

这里，平均负载是指单位时间内,处在可执行状态和不可中断睡眠状态的进程的平均数。Here, the average load refers to the average number of processes in the executable state and the uninterruptible sleep state per unit time.
SMA具体为将一段时间内的数据按照时间顺序排序，取出某一时间段内的数据进行平均，并将时间段向前移动一个单位，再进行平均，以此类推。SMA的计算公式为：SMA specifically sorts the data within a period of time in chronological order, takes out the data within a certain period of time and averages it, and then moves the period forward by one unit and averages it again, and so on. The calculation formula of SMA is:
SMA_n＝\frac{1}{n}\sum_{i＝0}^{n-1}x_{t-i}SMA_n＝\frac{1}{n}\sum_{i＝0}^{n-1}x_{t-i}
其中，SMA_n表示n个时间段内的平均值，\frac{1}{n}\表示1/n，x_{t-i}表示在时间t-i时刻的数据，sum_{i＝0}^{n-1}x_{t-i}表示对i取值0到n-1的数据x_{t-i}进行求和，n为自然数。Among them, SMA_n represents the average value in n time periods, \frac{1}{n}\ represents 1/n, x_{t-i} represents the data at time t-i, sum_{i＝0}^{n-1}x_{t-i} represents the sum of data x_{t-i} with values of i from 0 to n-1, and n is a natural number.

CPU的1分钟平均负载、5分钟平均负载和15分钟平均负载分别为CPU在1分钟内的平均负载、CPU在5分钟内的平均负载和CPU在15分钟内的平均负载。平均负载的值越小表示系统的工作量越少、负荷越低，平均负载的值越高表示系统的工作量越多、负荷越高。The 1-minute average load, 5-minute average load, and 15-minute average load of the CPU are the average load of the CPU in 1 minute, 5 minutes, and 15 minutes, respectively. The smaller the average load value, the less workload and the lower the load of the system. The higher the average load value, the more workload and the higher the load of the system.
通过对目标器件的使用数据进行均值算法处理，得到一段时间内的平均负载，并根据平均负载确定负载变化趋势信息，以及将负载变化信息显示在中控屏上，有效提升了呈现的目标器件的性能状况和趋势的准确性。By applying the mean algorithm to the usage data of the target device, the average load over a period of time is obtained, and the load change trend information is determined based on the average load, and the load change information is displayed on the central control screen, which effectively improves the accuracy of the performance status and trend of the target device presented.

该实现方式通过基于未来预设时间段的驾驶场景和/或未来预设时间段各应用对应的目标器件的使用情况，生成针对至少一个应用程序的工作模式调整策略，提升了生成的工作模式调整策略的有效性和可靠性，有效避免了目标器件因过载发生卡顿，影响用户体验。This implementation method generates a working mode adjustment strategy for at least one application based on driving scenarios in a future preset time period and/or usage of target devices corresponding to each application in a future preset time period, thereby improving the effectiveness and reliability of the generated working mode adjustment strategy and effectively avoiding the target device from freezing due to overload, which affects the user experience.

执行主体可根据已使用内存与总内存的比值来确定总内存使用率，其中，已使用内存包括已用内存和缓存/缓冲区内存。已用内存是指当前被进程使用的内存，包括正在运行的程序和其他系统进程所占用的内存。缓存/缓冲区内存是指操作系统为了优化磁盘IO而暂时存储的数据，当需要更多内存时，这部分内存可以被释放，给应用程序或系统进程使用。The execution subject can determine the total memory usage rate based on the ratio of used memory to total memory, where used memory includes used memory and cache/buffer memory. Used memory refers to the memory currently used by the process, including the memory occupied by running programs and other system processes. Cache/buffer memory refers to data temporarily stored by the operating system to optimize disk IO. When more memory is needed, this part of memory can be released for use by applications or system processes.
执行主体可根据指定时间段内的总内存使用率，确定平均内存使用率。例如，执行主体可通过采用SMA、EMA等均值算法分别对CPU及内存的使用数据进行处理，生成CPU平均负载(即系统平均负载)和内存平均负载。执行主体可分别对CPU及内存的使用数据进行傅里叶变换，生成CPU使用数据的频谱特征和内存使用数据的频谱特征。执行主体可通过预设的回归模型分别对CPU和内存的负载信息进行处理，生成CPU负载变化趋势信息和内存负载变化趋势信息。执行主体可分别对各应用的CPU占用率、各应用的内存使用量进行统计，生成各应用CPU占用百分比和各应用内存使用量。The execution subject may determine the average memory usage rate based on the total memory usage rate within a specified time period. For example, the execution subject may process the CPU and memory usage data respectively by using averaging algorithms such as SMA and EMA to generate the CPU average load (i.e., the system average load) and the memory average load. The execution subject may perform Fourier transform on the CPU and memory usage data respectively to generate the spectrum characteristics of the CPU usage data and the spectrum characteristics of the memory usage data. The execution subject may process the CPU and memory load information respectively by using a preset regression model to generate CPU load change trend information and memory load change trend information. The execution subject may respectively count the CPU occupancy rate of each application and the memory usage of each application to generate the CPU occupancy percentage of each application and the memory usage of each application.
通过设置目标器件同时包括CPU和内存，并将CPU和内存的使用情况显示在车载系统的中控屏上，进一步提升了呈现的目标器件的性能状况和趋势的全面性。By setting the target device to include both the CPU and memory, and displaying the CPU and memory usage on the central control screen of the vehicle system, the comprehensiveness of the performance status and trends of the target device presented is further improved.

If so, a list of application processes recommended for closure can be generated based on at least one of the memory usage of each application, the CPU usage of each application, and the duration of each application being in an untriggered state.
具体地，若当前车载系统中CPU使用率大于等于对应的预警值，执行主体可统计当前运行中的各应用程序的处于未触发状态的持续时长，并将持续时长大于等于预设时长阈值的应用添加至推荐关闭的应用进程列表。预设时长阈值可根据经验、实际需求设定，例如，20分钟、30分钟等，本公开对此不作限定。Specifically, if the CPU usage rate in the current vehicle system is greater than or equal to the corresponding warning value, the execution subject can count the duration of each currently running application in the untriggered state, and add the application with a duration greater than or equal to the preset duration threshold to the list of application processes recommended for closure. The preset duration threshold can be set based on experience and actual needs, for example, 20 minutes, 30 minutes, etc., and this disclosure does not limit this.
通过响应于确定使用情况中存在一项或多项指标大于等于对应的预警值，基于各应用程序内存占用量、各应用程序CPU占用量、各应用程序处于未触发状态的持续时长中的至少一项，生成推荐关闭的应用进程列表，有助于及时提醒用户对当前系统进行优化和维护，保障系统稳定运行。In response to determining that there are one or more indicators in the usage that are greater than or equal to the corresponding warning values, a list of application processes recommended for closure is generated based on at least one of the memory usage of each application, the CPU usage of each application, and the duration that each application is in an untriggered state.
