Detailed Description
As can be seen from the description of the background art, in the related art, in the operation control scheme applied to the electronic rearview mirror, under the condition that a plurality of functional modules operate simultaneously, there is a problem of resource allocation tension, so that smooth operation of the system cannot be ensured.
Taking an electronic rearview mirror on a car as an example, in order to ensure the safety of the car, the surrounding environment of the car needs to be monitored, so that the electronic rearview mirror installed on the car needs to start the function of driving recording all the time to record a video in real time to record the surrounding environment of the car. Meanwhile, in the driving process, a user may need to start the navigation function of the electronic rearview mirror and start the music playing function; therefore, under the condition that a plurality of functions operate simultaneously, the occupancy rate of the CPU resource of the electronic rearview mirror system can be up to more than 80%, if the electronic rearview mirror starts the audio playing function again, the phenomenon of blocking occurs, and smooth operation of the audio playing function cannot be guaranteed.
Based on this, according to the operation control scheme provided by the embodiment of the present invention, when it is detected that any one of the navigation function module and the voice interaction function module in the electronic rearview mirror enters the broadcast voice state, the operation parameters of the video recording function module in the electronic rearview mirror are adjusted to release part of resources in the CPU resources occupied by the video recording function module in the operation process, so that the electronic rearview mirror has enough CPU resources to support the operation of the audio broadcast function of the navigation function module and the voice interaction function module, and thus the electronic rearview mirror does not have a jam phenomenon during the operation of the audio broadcast, thereby ensuring smooth operation of the system.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a schematic flow chart of an implementation of the operation control method according to the embodiment of the present invention. Referring to fig. 1, the operation control method of the present embodiment specifically includes the following steps:
the operation control method of the embodiment is applied to an electronic rearview mirror, which may include a music function module, a navigation function module, a voice interaction function module and a video recording function module, and during initial operation, corresponding CPU resources need to be allocated to each function module, for example, 10% of CPU resources are allocated to the music function module, 10% of CPU resources are allocated to the navigation function module, 20% of CPU resources are allocated to the voice interaction function module, 50-60% of CPU resources are allocated to the video recording function module, and an occupancy rate of 50-60% of CPU resources during operation of the video recording function module corresponds to a video frame rate of 30 FPS.
After the initial configuration, the music function module and the video function module of the electronic rearview mirror are started in real time, if the navigation function module or the voice interaction function module is started at the same time, the occupancy rate of the CPU resource of the electronic rearview mirror system may be up to more than 80%, the phenomenon of jamming will occur, and thus the smooth operation of the audio playing function cannot be ensured. Therefore, the embodiment of the invention aims to ensure that the phenomenon of blockage can not occur in the audio broadcasting process when the audio broadcasting is started by any one of the navigation function module and the voice interaction function module of the electronic rearview mirror, thereby achieving the aim of smooth operation of the whole set of system.
In the embodiment of the present invention, the electronic rearview mirror may further include an Audio Track module (Audio Track), the Audio Track module may detect an Audio signal, and the Audio Track module may detect which functional module is sending the Audio signal. Therefore, in the embodiment of the invention, the broadcasting voice states of the navigation function module and the voice interaction function module in the electronic rearview mirror can be detected through the Audio Track.
In the embodiment of the present invention, the Audio Track may detect whether there is an Audio signal through the first state identification bit, and may determine which functional module the Audio signal comes from through the second state identification bit. When the first state identification position represents that an audio signal exists and the second state identification position determines that any one of the navigation function module and the voice interaction function module in the electronic rearview mirror enters a broadcast voice state, the operation parameters of the video function module in the electronic rearview mirror are adjusted.
Specifically, the operation parameter of the video recording function module may be a video frame rate, and adjusting the operation parameter of the video recording function module in the electronic rearview mirror includes: and reducing the video frame rate of the video functional module. Partial resources in CPU resources occupied by the video function module in the running process can be released by reducing the video frame rate of the video function module; for example, the number of frames transmitted per Second (FPS) is reduced to 15FPS, and at this time, about 20% of the CPU resource occupancy rate can be released, and the released CPU resource can support the operation of the navigation function module or the voice interaction function module.
In practical application, the operation parameters of the video function module, that is, the video frame rate of the video function module, may be determined by reading the camera parameters of the monitoring camera installed on the electronic rearview mirror.
In summary, in the embodiments of the present invention, when it is detected that any one of the navigation function module and the voice interaction function module in the electronic rearview mirror enters the broadcast voice state, the operation parameter of the video recording function module in the electronic rearview mirror is adjusted to release part of the resources in the CPU resources occupied by the operation process of the video recording function module, so that the electronic rearview mirror has enough CPU resources to support the operation of the audio broadcast function of the navigation function module and the voice interaction function module, and thus the electronic rearview mirror does not have a stuttering phenomenon during the operation of the audio broadcast, thereby ensuring smooth operation of the system.
Example two
As can be seen from the description of the first embodiment, the reason why the whole system is not smooth due to the occurrence of the jamming in the audio broadcasting process is that the CPU resource allocated by the system is insufficient, so that the system cannot support the normal operation of the function.
Specifically, fig. 2 is a second schematic flow chart of the implementation of the operation control method according to the embodiment of the present invention, and referring to fig. 2, the operation control method according to the embodiment specifically includes the following steps:
in the embodiment of the present invention, the electronic rearview mirror may include a video recording function module, and may also include other function modules, such as a music function module, a navigation function module, and a voice interaction function module, and during initial operation, corresponding CPU resources need to be allocated to each function module, for example, 10% of CPU resources are allocated to the music function module, 10% of CPU resources are allocated to the navigation function module, 20% of CPU resources are allocated to the voice interaction function module, 50-60% of CPU resources are allocated to the video recording function module, and 50-60% of CPU resource occupancy rate during operation of the video recording function module corresponds to a video frame rate of 30 FPS.
Meanwhile, the corresponding relationship between the CPU resource occupancy rate and the video frame rate needs to be set for the video recording function module, for example, when the video frame rate is 30FPS, the CPU resource occupancy rate is about 50%, and when the video frame rate is 15FPS, the CPU resource occupancy rate is about 30%.
Fig. 3 is a schematic diagram of a detailed implementation flow of step 201 in the implementation flow shown in fig. 2, and referring to fig. 3, after determining CPU resource occupancy rates of the functional modules, step 201 specifically includes:
here, the target operation parameter is a parameter in real-time operation of the video recording function module, that is, a video frame rate in a real-time video recording process, and the target operation parameter of the video recording function module, that is, the video frame rate of the video recording function module, may be determined by reading a camera parameter of a monitoring camera mounted on the electronic rearview mirror.
here, in the initial configuration, the corresponding relationship between the CPU resource occupancy rate and the video frame rate may be set for the video function module; therefore, when the target operation parameters of the video recording function module are detected, the CPU resource occupancy rate of the video recording function module can be determined by inquiring the corresponding relation.
In the embodiment of the invention, the occupancy rate of the CPU resource is directly detected, and when the occupancy rate is higher than the preset threshold value, the CPU resource is released by adjusting the operation parameters of the video recording function module, so that the normal operation of the newly added function module is ensured, and the aim of simultaneously operating all the function modules of the electronic rearview mirror is fulfilled.
EXAMPLE III
When the electronic rearview mirror is initially started, the video frame rate of the video function module is determined, so that when any one of the navigation function module and the voice interaction function module is detected to enter a broadcast voice state, the condition that the CPU resource occupancy rate is too high can be directly determined, and the operation parameters of the video function module in the electronic rearview mirror need to be adjusted. After the adjustment, the video frame rate of the video function module changes, and at this time, whether the operation parameters of the electronic rearview mirror need to be adjusted again or not can be determined by detecting the occupancy rate of the CPU resource in the operation process of the electronic rearview mirror, so as to ensure the normal operation of the newly added function module.
Specifically, fig. 4 is a third schematic flow chart of the implementation of the operation control method according to the embodiment of the present invention, and referring to fig. 4, the operation control method according to the embodiment specifically includes the following steps:
and 304, when the occupancy rate is greater than the preset threshold value, adjusting the operation parameters of the video recording function module in the electronic rearview mirror again so as to release part of the resources in the CPU resources occupied by the video recording function module in the operation process.
