The following describes a method, a device, a vehicle and a storage medium for storing vehicle-mounted display screen data according to embodiments of the present application with reference to the accompanying drawings. Aiming at the problems that the traditional display screen mentioned in the background art cannot process and store data, so that data playback cannot be realized, and the display screen is high in maintenance cost and easy to lose data in the development and maintenance processes, the application provides a storage method of vehicle-mounted display screen data. Therefore, the problems that the traditional display screen cannot process and store data, so that data playback cannot be realized, the display screen is high in maintenance cost and easy to lose data in the development and maintenance process are solved, the screen data are transferred to a vehicle host under the condition that the activation condition is met by monitoring the display screen data, the screen data are exported when the screen data are analyzed and optimized, and the safety of data storage is improved.
Specifically, fig. 2 is a flow chart of a method for storing vehicle-mounted display screen data according to an embodiment of the present application.
As shown in fig. 2, the method for storing the data of the vehicle-mounted display screen includes the following steps:
in step S201, screen data of at least one in-vehicle display screen is received.
Specifically, as shown in fig. 3, the vehicle host or the meter in the embodiment of the application adopts a novel vehicle-mounted display screen system, that is, the vehicle-mounted display screen and the controller respectively use different processors to analyze and process the screen data, and store the screen data through the vehicle host, so that when the vehicle is in a power-on state, the vehicle-mounted display screen and the host are started and receive the screen data of at least one vehicle-mounted display screen, and after the screen data is received, the screen data is temporarily cached in the vehicle host, so that the screen data can be called in time.
In step S202, it is determined whether the screen data satisfies a preset dump activation condition.
The preset dump activation condition may be an activation condition set by a person skilled in the art according to actual needs, or may be an activation condition obtained through computer simulation, which is not limited herein specifically.
Specifically, after the vehicle host machine in the embodiment of the present application receives the screen data of at least one vehicle-mounted display screen, it is first required to determine whether the at least one screen data meets a preset transfer activation condition, and when the preset transfer activation condition is met, transfer the at least one screen data to the storage area.
In step S203, if the screen data meets the preset dump activation condition, the screen data is stored in the target RAM, and at the same time, the screen data in the target RAM is dumped to the target storage device until the whole vehicle is powered down, and the dump of the screen data in the target RAM to the target storage device is stopped.
Specifically, as shown in fig. 4, in the embodiment of the present application, if the screen data received by the vehicle host meets a preset dump activation condition, for example, the fluctuation range of PWM (Pulse width modulation ) exceeds a certain range or the temperature is too high, at this time, the screen processor sends a screen data transmission instruction to the vehicle host and sends the screen data to the vehicle host, after the vehicle host receives the screen data, the vehicle host firstly stores the screen data in the RAM, and then, the screen data in the target RAM is dumped to the target storage device, for example, a hard disk, until the whole vehicle is powered down, and the screen data in the target RAM is stopped from being dumped to the target storage device.
It should be noted that, in the embodiment of the present application, since the screen data received by the host computer of the vehicle meets the preset dump activation condition, after the whole vehicle is powered down, the screen data stored in the target storage device is still reserved, and cannot be covered by other data and cannot be lost.
Further, in the embodiment of the present application, after the screen data in the target RAM is transferred to the target storage device, the method further includes: judging whether a screen data reading instruction is received or not; and if the screen data reading instruction is received, exporting the screen data in the target storage device to a preset storage device.
Specifically, after the screen data in the target RAM is transferred to the target storage device, if the user needs to read the screen data, the user needs to send a reading instruction of the screen data to the vehicle host, and after receiving the reading instruction of the screen data, the vehicle host can export the screen data in the target storage device to a preset storage device, such as a usb disk, a diagnostic apparatus, a cloud system, and other devices, so that the user can use the screen data.
Further, in the embodiment of the present application, after exporting the screen data in the target storage device to the preset storage device, the method further includes: judging whether the screen data is exported or not; if the screen data is exported, generating a data deleting query instruction of the target storage device; judging whether a deleting instruction sent by a user based on the data deleting inquiry instruction is received or not; and if the deleting instruction is received, deleting the screen data of the target storage device.
Specifically, in the embodiment of the present application, after exporting the screen data in the target storage device to the preset storage device, whether the screen data is exported is determined, and after the screen data is exported, a data deletion query instruction of the target storage device is generated to the vehicle host, after the user receives the deletion instruction, whether to delete the screen data of the target storage device can be selected according to the use requirement or the importance degree of the screen data, and if the screen data has no use requirement, the screen data of the target storage device is deleted.
Further, in the embodiment of the present application, after determining whether the screen data meets the preset dump activation condition, the method further includes: if the screen data does not meet the preset transfer activation condition, the screen data is always stored in the RAM.
Further, in the embodiment of the present application, after determining that the screen data does not meet the preset dump activation condition, the method further includes: judging whether the current vehicle meets a preset power-down condition or not; if the current vehicle meets the preset power-down condition, deleting screen data in the RAM after the current vehicle is powered down.
The preset power-down condition may be a power-down condition set by a person skilled in the art according to a power-down requirement of the vehicle, or may be a power-down condition obtained through computer simulation, which is not limited herein.
Specifically, in the embodiment of the present application, if the screen data received by the vehicle host does not meet the preset transfer activation condition, the screen data is always stored in the RAM, and after the current vehicle meets the preset power-down condition, the screen data in the RAM is deleted to release the storage area of the RAM.
According to the method for storing the vehicle-mounted display screen data, the screen data of at least one vehicle-mounted display screen are received, when the screen data meet the preset transfer activation condition, the screen data are stored in the target RAM, the screen data in the target RAM are transferred to the target storage device, and the transfer of the screen data in the target RAM to the target storage device is stopped until the whole vehicle is powered down. Therefore, the problems that the traditional display screen cannot process and store data, so that data playback cannot be realized, the display screen is high in maintenance cost and easy to lose data in the development and maintenance process are solved, the screen data are transferred to a vehicle host under the condition that the activation condition is met by monitoring the display screen data, the screen data are exported when the screen data are analyzed and optimized, and the safety of data storage is improved.
