Description
Technical Field
The invention relates to the technical field of vehicle-mounted data processing, in particular to a vehicle-mounted edge side data processing system.
Background
Conventional vehicle-mounted sensing systems typically perform a single function, i.e., the sensing units (sensors) are typically configured to have a distinct and single functional requirement, and typically the sensing systems of different functions are also independent of each other. Along with the development of the intelligent development of automobiles, a single-function sensing system obviously cannot meet application requirements, and one of the main performances is that the same sensing signals can be largely multiplexed to realize more functional requirements, for example, a laser radar can be used for self-adaptive cruising and following automobiles and automatic driving, and can also be used for obstacle detection, 3D scene reconstruction and the like. Therefore, the common hardware system architecture is changed into that the sensing modules of each sensing system are formed into independent sensing layers for acquiring various sensing data and are connected with the upper layer system through a unified interface platform. At the upper level of the sense layer, there is typically a data layer for classifying, identifying, storing and transmitting data. And on the data layer, a part of the system is provided with a data fusion layer for preliminary fusion operations such as preprocessing, classifying and the like of the data. Above the fusion layer, the user builds applications, often referred to as the application layer, according to the scene problem requirements.
In the above architecture, in order to adapt to future functionality expansion possibilities of the application layer, the solution of the perception layer is generally based on the possible maximum functionality requirement scenario (and set redundancy amount), and the data acquisition and storage of the perception layer are set. Such strategies result in long-term undeveloped predictive functionality of the system at the application level, or the existence of conflicting functionality with a particular vehicle model or scenario can be crowded with data acquisition resources. One of the specific manifestations is that the sense layer can have severely redundant data acquisition. Redundant data can result in significant amounts of inefficiency in computing resources, storage resources, communication, bandwidth resources, etc. In particular, computing resources, communication and bandwidth resources are particularly scarce for vehicle-level systems, and redundant resource occupation seriously affects the implementation of the core functions of the system. Including real-time nature of local decisions, priority traffic, etc., are forced to degrade.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1:
referring to fig. 1, fig. 1 is a schematic structural diagram of a vehicle-mounted edge side data processing system according to an embodiment of the present invention.
As shown in fig. 1, an in-vehicle edge side data processing system has: an application monitoring module 10, a data awareness module 20 and a dynamic configuration module 30.
The application monitoring module 10 is used for monitoring application dynamic data of the vehicle-mounted application and determining data demand information of the vehicle-mounted application according to the application dynamic data; the data sensing module 20 is used for driving the sensing component to acquire sensing data according to the corresponding configuration information; the dynamic configuration module 30 is configured to dynamically update the configuration information of the sensing component according to the data requirement information and the sensing data.
In this embodiment, the vehicle-mounted edge side data processing system is provided with an application monitoring component at the application layer, and the application monitoring component is used as the application monitoring module 10 to monitor application dynamic data of each vehicle-mounted application in the application layer and generate a monitoring report. Alternatively, the application dynamic data may include new installs, deletions, changes in settings or operating states/conditions, etc. of the in-vehicle application.
In a traditional vehicle-mounted system, as data acquisition of a sensing component is not limited, a sensing layer usually performs data acquisition and storage based on a possible maximum functional requirement scene (and redundancy setting), so that the vehicle-mounted system needs to process a large amount of redundant data, further, computing resources, communication and bandwidth resources are affected, particularly scarce scheduling and allocation use is performed on the vehicle-mounted system, and core functions such as system operation and local decision making are seriously affected. Therefore, the embodiment sets the corresponding configuration information for the sensing component in the sensing layer, and when the sensing layer performs data acquisition, the acquisition action is executed according to the configuration information corresponding to the sensing component, so that only the required data, but not all the data, is acquired, and the purpose of reducing the data redundancy is achieved.
For the vehicle-mounted system, how to set the configuration information of the sensing component determines whether the vehicle-mounted system can realize the decision factor that the system resource and the vehicle-mounted system performance are balanced. In this embodiment, application dynamic data of the vehicle-mounted application is acquired to determine data demand information of the vehicle-mounted application, meanwhile, sensing data acquired by the sensing component according to corresponding configuration information is acquired, and finally, configuration information of the sensing component is dynamically adjusted according to differences between the data demand information and the sensing data, so that configuration information setting of the sensing component is achieved.
Compared with the data acquisition strategy which is adopted by the sensing layer in the existing vehicle-mounted system and is not configurable or statically configured, the data acquisition strategy of the sensing layer is changed into a dynamic mode or a mode which is adjustable according to the condition that a user uses the vehicle-mounted application based on the data demand information of the vehicle-mounted application and the sensing data acquired by the sensing component, so that the sensing component of the sensing layer can acquire data required at the current moment, but not all data, balance between system resources and performance of the vehicle-mounted system is achieved, and the system resources are saved as much as possible on the premise that the vehicle-mounted system has higher performance.
Example 2:
in a preferred embodiment, the vehicle-mounted application is configured with an application configuration file, and the application configuration file stores data requirement information of the vehicle-mounted application when different application dynamic data are provided.
On this basis, the application monitoring module 10 includes: the method comprises the steps of applying a dynamic data acquisition unit and a data demand information matching unit; the application dynamic data acquisition unit acquires application dynamic data of the vehicle-mounted application; and the data demand information matching unit matches corresponding data demand information in an application configuration file according to the application dynamic data.
In this embodiment, in order to implement real-time data demand information of the vehicle-mounted application, the corresponding vehicle-mounted application needs to be configured with an application configuration file in addition to its own functional program. Optionally, the application profile is used to record data requirements of the application or of different configurations, different functional states or different operating conditions of the application. Therefore, when determining the data requirement information by using the obtained dynamic data, the application monitoring module 10 may obtain a real-time effective configuration table by calling an application configuration file configured by each vehicle-mounted application at the time of installation according to the data requirement information corresponding to different dynamic data stored in the application configuration file, where the configuration table is different from the application configuration file in recording the complete data requirement, and only records the data requirement information in the current use state or the state where the application configuration file may be in. Alternatively, the data demand information may be a data acquisition type, a data acquisition frequency, or the like.
For example, the types of data collection of the vehicle are usually different when the vehicle performs wiper control and in-vehicle temperature adjustment, and the vehicle-mounted system can determine the different types of data collection according to the application dynamic data; for example, the data acquisition types of the vehicle may be the same when the vehicle performs automatic driving and performs obstacle detection, but the data acquisition frequencies are generally different, and the vehicle-mounted system can determine different data acquisition frequencies according to application dynamic data.
Compared with the mode of all data collection and storage which are generally adopted when the traditional vehicle-mounted system executes the data collection of the sensing layer, when the data calling instruction of the vehicle-mounted application is received, the data corresponding to each vehicle-mounted application is called, the information difference between the data collection and the data calling exists in the process, namely the data requirement of the vehicle-mounted application cannot be transmitted to the sensing layer, the sensing layer can only conduct the data collection according to the scene of the maximum functional requirement, and a large amount of system resource waste is caused. In this embodiment, the data demand information of the vehicle-mounted application in different states is extracted in advance, and then the configuration file according to which the sensing component executes the acquisition action is updated according to the real-time state of the vehicle-mounted application, so as to obtain the real-time demand data of the vehicle-mounted application, break through the information barrier between data acquisition and data call, directly dock the data demand of the vehicle-mounted application with the perception layer, intuitively determine the data demand information at the perception layer, realize the acquisition of corresponding data, reduce the burden of redundant data processing on system resources, and improve the system performance.
Example 3:
in a preferred embodiment, the application monitoring module 10 further comprises: a monitoring mode switching unit is applied.
The application monitoring mode switching unit executes the application monitoring action according to the mode switching instruction when receiving the mode switching instruction; when the mode switching instruction is to start application monitoring, the application monitoring action is as follows: acquiring application dynamic data of the vehicle-mounted application in real time, and matching corresponding data demand information in an application configuration file according to the application dynamic data; when the mode switching instruction is to switch off the application monitoring, the application monitoring action is as follows: and suspending to acquire application dynamic data of the vehicle-mounted application, and matching corresponding data demand information in the application configuration file according to the latest historical application dynamic data.
In this embodiment, since the system resources are also consumed for monitoring the vehicle-mounted application, the application monitoring module 10 is provided with an application monitoring mode switching mechanism. The application monitoring module 10 senses a mode switching instruction in real time, can normally acquire application dynamic data of the vehicle-mounted application in real time when receiving an application monitoring instruction, and matches corresponding data demand information in an application configuration file according to the application dynamic data; when receiving the closing application monitoring instruction, in order to maintain the normal acquisition of the data demand information, the acquisition of the application dynamic data of the vehicle-mounted application can be suspended, the latest historical application dynamic data is called, and the corresponding data demand information is matched in the application configuration file.
Therefore, in this embodiment, the system resource allocation is further effectively balanced, and the monitoring mode of the vehicle-mounted application is switched according to the monitoring mode switching instruction, so as to implement finer management and allocation of the system resource, and alleviate the contradiction between the system resource and the system performance in the case of more extreme system resource allocation.
Example 4:
in a preferred embodiment, the application monitoring module 10 further comprises: and a mode switching instruction generation unit.
The mode switching instruction generating unit obtains a system resource use load and generates a mode switching instruction set according to the system resource use load; when the system resource usage load meets a load overload condition, the mode switching instruction set comprises a group of mode switching instructions for starting application monitoring and a group of mode switching instructions for closing application monitoring, which are executed every a first preset time; when the system resource usage load does not meet the load overload condition, the mode switching instruction set comprises a group of mode switching instructions for starting the application monitor and a group of mode switching instructions for closing the application monitor, which are executed every second preset time.
It should be noted that, the mode switching instruction may be used to switch the monitoring mode of the vehicle-mounted application, so as to implement finer management and allocation of the system resources, so that the generation of the mode switching instruction will determine the fineness of the management and the rationality of allocation of the system resources.
In this embodiment, whether the system resource usage load meets the load overload condition is determined by considering the system resource usage load, so as to switch the monitoring mode of the application monitoring module 10, when the current system resource usage load meets the load overload condition, a group of mode switching instructions for starting application monitoring and a group of mode switching instructions for closing application monitoring are executed every first preset time, and when the current system resource usage load does not meet the load overload condition, a group of mode switching instructions for starting application monitoring and a group of mode switching instructions for closing application monitoring are executed every second preset time, so that the time or frequency for executing application monitoring in unit time is set by configuring different first preset time and second preset time, thereby realizing finer management and allocation of system resources and alleviating contradiction between system resources and system performance in a relatively extreme system resource allocation scene.
For example, when the current system resource usage load meets the load overload condition, fewer application monitoring times or application monitoring times with lower frequency in a unit time are allocated to the application monitoring module 10, so that when the system resource is in a scene of a relatively limited system resource allocation such as overload, the resource quota of the application monitoring is reduced, and the system processing capacity is improved.
For example, the first preset time may be adjusted according to the occupancy rate of the system resource usage load or the duration time when the system resource usage load is overloaded, for example, the higher the occupancy rate, the longer the duration time, and the longer the first preset time is adjusted; the second preset time can be adjusted according to the occupancy rate of the system resource usage load or the duration time when the load is not overloaded, for example, the lower the occupancy rate is, the longer the duration time is, and the longer the second preset time is adjusted. Therefore, the action of application monitoring is dynamically adjusted according to the condition of the system resource using load, and the system has higher system flexibility and scene suitability.
Example 5:
in a preferred embodiment, the application monitoring module 10 further comprises: and a data demand information updating unit.
When detecting that the vehicle-mounted application executes the application configuration file updating action, the data demand information updating unit matches updated data demand information in the updated configuration file by using the acquired application dynamic data; when the data demand information updating unit detects that the vehicle-mounted application executes the updating action, the application dynamic data and the configuration file of the updated vehicle-mounted application are acquired, and the updated data demand information is matched in the updated configuration file by utilizing the application dynamic data.
In some scenarios, the application configuration file of the vehicle-mounted application is updated or the vehicle-mounted application is updated, and in this embodiment, the updated data requirement information may be matched by using the obtained application dynamic data and the updated application configuration file, or by using the updated application dynamic data and the configuration file of the vehicle-mounted application. In practical application, the updating of the application configuration file may be adaptive adjustment of the application configuration file of the vehicle-mounted application according to the use requirement of the user, and the updating of the vehicle-mounted application may be installation, uninstallation or updating of the vehicle-mounted application.
For example, when the driver of the vehicle performs the replacement, because the replaced driver is unfamiliar with the size, performance and power of the vehicle, in order to ensure the driving safety, the application configuration file of the vehicle-mounted application may be adjusted in a manual or automatic manner, for example, the data requirement information corresponding to the obstacle detection performed in the application configuration file is adjusted to be more sensor data or more sensor data acquisition frequency.
When the vehicle-mounted application is upgraded, the application configuration file of the installed, uninstalled or updated vehicle-mounted application is manually or automatically updated to adapt to the data requirements of different versions of vehicle-mounted applications when different functions are realized.
Therefore, the embodiment meets the use requirements of different vehicles or the data requirements of different functions of the vehicle-mounted application by monitoring the update of the vehicle-mounted application or the update of the application configuration file corresponding to the vehicle-mounted application, and the optimization of the overall performance is realized from the system level.
Example 6:
in a preferred embodiment, the dynamic configuration module 30 includes: a demand comparison unit and a dynamic configuration unit.
The requirement comparison unit generates a dynamic configuration table according to the data requirement information and the perception data of the vehicle-mounted application; the dynamic configuration unit generates a dynamic configuration instruction according to the dynamic configuration table, and dynamically updates the configuration information of the sensing component based on the dynamic configuration instruction; the dynamic configuration table stores the data difference between the perception data and the data demand information, and the dynamic configuration instruction is used for adjusting the data acquisition strategy in the configuration information.
