Local memory device described in step B is the hardware device with data storage function that can be connected with blue light player, conveniently can give correlation engineering teacher by local memory device storing daily record file.
On the other hand, construct a kind of Blu-ray player daily record local storage, described Blu-ray player is the embedded device based on (SuSE) Linux OS, comprising:
Daily record writing module, after receiving user instruction, linux kernel loads virtual terminal device driver, creates a virtual terminal equipment, is also all written in same kernel buffers by virtual console reception kernel log and application log;
Daily record memory module, after receiving user instruction, reads log information and is saved in the form of a file in local memory device from described kernel buffers.
In daily record writing module and daily record memory module, described user instruction is that user is undertaken by the UI operation interface of Blu-ray player operating the instruction produced.
Application log described in daily record writing module is the application program realizing Blu-ray player function, the mode of employing cyclic buffer, described buffer zone.
Local memory device described in daily record memory module is the hardware device with data storage function that can be connected with blue light player.
Implement the local storage means of a kind of Blu-ray player daily record of the present invention and device, be applied in the Blu-ray player based on (SuSE) Linux OS, there is following beneficial effect: obtain while realizing kernel log and application log, simple to operate, without the need to just can journal file be got by professional tool, correlation engineering teacher effectively can be helped to understand Blu-ray player produced problem and defect, thus product quality is got a promotion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the local storage means process flow diagram of Blu-ray player daily record of one embodiment of the invention;
Fig. 2 is the Blu-ray player UI Operation interface diagram of one embodiment of the invention;
Fig. 3 is the Blu-ray player daily record local storage structural drawing of one embodiment of the invention.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
Described Blu-ray player is the embedded device based on (SuSE) Linux OS.
Be illustrated in figure 1 the process flow diagram of the local storage means of a kind of Blu-ray player daily record of one embodiment of the invention, comprise:
100, after receiving user instruction, linux kernel loads virtual terminal device driver, creates a virtual terminal equipment, is also all written in same kernel buffers by virtual console reception kernel log and application log;
101, after receiving user instruction, from described kernel buffers, read log information and be saved in the form of a file in local memory device.
In step 100 and step 101, described user instruction is that user is undertaken by the UI operation interface of Blu-ray player operating the instruction produced.
Application log described in step 100 is the application program realizing Blu-ray player function, and blue light player is a kind of embedded device based on (SuSE) Linux OS.
The mode of employing cyclic buffer, described buffer zone.
Local memory device described in step 101 is the hardware device with data storage function that can be connected with blue light player, as USB flash disk etc.Conveniently correlation engineering teacher can be given by local memory device storing daily record file.
When user needs log information this locality to store, open this function by the UI operation of player, kernel loads virtual terminal driver, creates a virtual terminal equipment and in kernel, distributes a block buffer.When kernel print log, virtual console can receive this message and write buffer zone.Meanwhile, if application program print log, then the standard output stdout of application program is redirected to virtual terminal equipment, log information is written into buffer zone.
The size of buffer zone can be specified, and such as, in use, can the size of appointed buffer be 2M.The mode of employing cyclic buffer, buffer zone, the storage unit backpointer writing the end of buffer zone points to the first address of this storage unit, namely, after log information exceedes the size of buffer zone, the information write at first will be eliminated the new daily record of guarantee and can be written into.During due to Blu-ray player program appearance mistake, log information will stop, so the log information that can react when making a mistake always in the end just is written into, can not being capped.So the log information preserved can react situation when making a mistake.
End user is undertaken operating by Embedded UI interface again and from this equipment, reads log information and be saved in local memory device with document form, is supplied to correlation engineering teacher.
As shown in Figure 2, for the Blu-ray player of one embodiment of the invention arranges surface chart and the UI operation interface of menu.There is provided respective selection to make user open or closing journal record and preserve journal file to the function of memory device arranging in menu 200 of Blu-ray player.For the consideration of security, described option is set to hide, and user inputs specific cryptosystem will eject interface 202.Journal file for user's unlatching or closing journal record and can be preserved to memory device in interface 202, and what Fig. 2 median surface 202 showed is preserving journal file to situation during local memory device.In Fig. 2,201 is the setting options of other conventional design.
Fig. 3 is a kind of Blu-ray player daily record local storage structural drawing of one embodiment of the invention, comprising:
Daily record writing module 300, after receiving user instruction, linux kernel loads virtual terminal device driver, creates a virtual terminal equipment, is also all written in same kernel buffers by virtual console reception kernel log and application log;
Daily record memory module 301, after receiving user instruction, reads log information and is saved in the form of a file in local memory device from described kernel buffers.
In daily record writing module 300 and daily record memory module 301, described user instruction is that user is undertaken by the UI operation interface of Blu-ray player operating the instruction produced.
Application log described in daily record writing module 300 is the application program realizing Blu-ray player function, the mode of employing cyclic buffer, described buffer zone.
Local memory device described in daily record memory module 301 is the hardware device with data storage function that can be connected with blue light player.
Should be understood that the specific implementation process of each device above-mentioned can be corresponding with the description of said method embodiment, be not described in detail herein.
Be understood that, although this invention is based on Blu-ray player Realization of Product, but only need change on a small quantity it, be applicable to other embedded devices based on (SuSE) Linux OS too, make user without the need to just can journal file be got by professional tool and feed back to slip-stick artist, effectively can help to solve the problem being difficult to copy to occurred in product, product quality is promoted further.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
