Description
Technical field
The present invention relates to LED display alignment technique field more particularly to a kind of protection sides of LED display correction data
Method and device.
Background technique
Currently, the alignment technique of LED display has been increasingly becoming LED display control program indispensability technology and has reached its maturity,
In order to guarantee the safety of correction data, it usually needs correction data is saved simultaneously in control system and LED display, even if such as
This, is influenced, it is likely that cause control system or LED by complicated field application environment such as weather, dust, electrical, electromagnetic field etc.
Correction data in display screen is lost, once and loss correction data, since system lacks preparatory diagnostic measures, it will do not having
In the case where any sign, the display for directly contributing LED display is abnormal, and scene needs operator aobvious from LED manually
Correction data is read in control system in display screen, or by upper computer software correction data be sent to control system or
In LED display, this all causes deleterious effect to field application and display effect, seriously affects the economy benefit of client
Benefit.
It can be seen that saving in the prior art to correction data although taking backup, but correction number can not be eliminated
According to the risk being destroyed, once being destroyed or being lost, need to update upgrading correction data at the scene, bring working efficiency low and
The problem of poor user experience, it would be highly desirable to improve.
Summary of the invention
The purpose of the present invention is to provide a kind of guard method of LED display correction data and devices, it is intended to solve existing
With the presence of the insurmountable correction data of technology maintenance convenience is poor, low efficiency and the problem of poor user experience.

And be not intended to limit the present invention.As description of the invention and it is used in the attached claims, unless on
Other situations are hereafter clearly indicated, otherwise "the" is intended to include plural form.
Fig. 1 shows a kind of implementation process of the guard method of LED display correction data provided in an embodiment of the present invention,
The executing subject of the guard method of LED display correction data in the present embodiment is that the protection of LED display correction data fills
It sets.For ease of description, only parts related to embodiments of the present invention are shown, and details are as follows:
In step s101, judge whether the correction data stored in control card and LED display module loses respectively.
Specifically, judge whether the correction data stored in control card loses and judge the school stored in LED display module
Whether correction data loses, and includes three kinds of situations: 1) correction data stored in control card and LED display module is not lost；2)
The correction data of one of storage is lost in both control card and LED display module；3) it is deposited in control card and LED display module
The correction data of storage is lost, and the corresponding concrete operations of these three situations are respectively such as step S102, step S103 and step
Described in S104.
In step s 102, if the correction data stored in control card and LED display module is not lost, control is controlled
Card is worked normally with LED display module.
Specifically, detect that the correction data stored in control card and LED display module is not lost, then it represents that when powering on
After starting, the correction data and LED display module that the correction data stored in control card is correct, stores in comparison control card are verified
The correction data of middle storage is identical, comparison herein, and the name including comparing the correction data stored in control card is with version
It is no identical, if all the same, determine that the correction data stored in control card and LED display module is not lost, controls control card
It is worked normally with LED display module.
In step s 103, if the correction data of one of storage is lost in both control card and LED display module,
Data duplication is corrected between control card and LED display module, control control card and LED display module work normally.
Specifically, it includes following two that the correction data of one of storage, which is lost, in both control card and LED display module
Kind situation: 1) correction data stored in control card is lost, and the correction data stored in LED display module is not lost；2) it controls
The correction data stored in card is not lost, and the correction data stored in LED display module is lost.Mould is shown in control card and LED
It is corrected data duplication between group and respectively corresponds above-mentioned two situations: 1) sending out the correction data stored in LED display module
It send to control card；2) correction data stored in control card is sent to LED display module.
In step S104, if the correction data stored in control card and LED display module is lost, abnormal mention is sent
Show information and close calibration function, control control card and LED display module work normally.
Specifically, aobvious for control card and LED when the correction data stored in control card and LED display module is lost
Show for mould group, the function in addition to correction is simultaneously unaffected, therefore, after correction data is all lost, closes calibration function
And the prompt information for sending calibration function exception reminds user to retransmit correction data.
Optionally, if the correction data stored in control card and LED display module is lost, abnormal prompt letter is sent
Breath, and the backup correction data stored in control card is read, backup correction data is sent to LED display module, control control
Card is worked normally with LED display module.
