Detailed ways

The specific implementation manners disclosed by the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

Fig. 1 is a flow chart of a method for saving LED display screen parameters according to an exemplary embodiment. As shown in Fig. 1, it is applied to a LED display screen control system, and the method includes:

In step 101, the LED display screen parameters to be saved are obtained.

Exemplarily, the LED display screen control system in the disclosed embodiments of the present invention may be control software installed on an electronic device for saving and loading LED display screen parameters and controlling lighting of the LED display screen. In the actual application process, the staff operates the LED display control system, such as clicking the button to save the LED display parameters to control the LED display control system to perform the function of saving the LED display parameters. After receiving the parameter saving instruction, the LED display control system acquires the LED display parameters to be saved.

In step 102, several data blocks written/read in the form of byte stream are set, and each type of LED display parameter is stored in a different data block according to the type of the LED display parameter.

For example, LED display parameters include multiple different types, and the types of LED display parameters can be manually defined by the staff. Before the LED display control system saves the LED display parameters, it is necessary to identify different types of parameters, so that the Different types of LED display parameters are stored in different data blocks.

Specifically, some LED display parameters that need to be saved in the LED display control system and the corresponding types can be shown in Table 1:

Table 1

It should be noted that the data block in the disclosed embodiments of the present invention is a special data block defined when saving parameters, that is, a data block written in a file in the form of a byte stream to store parameters, and when transferring data, it is also passed The byte stream reads the parameters from the file and loads the read parameters into the corresponding data blocks.

Specifically, block header information is set according to the type of LED display parameter, and the block header information includes data length information, data version information and data type information; according to the block header information corresponding to each type of LED display parameter and the LED display parameter , to obtain the data block corresponding to the type of the LED display parameter.

For example, when different types of LED display parameters are stored in independent data blocks, each data block includes block header information in the same format as the LED display parameters in addition to the LED display parameters. The block header information is used to quickly distinguish and record different LED display parameter information.

For example, block header information can be represented by the following code:

It can be seen from the code of the above block header information that each parameter assignment in the block header information structure represents a different meaning. The specific examples are as follows: Len=20; //20 means that the current data block size is 20; Version= 10; //10 represents the version information, different version information can be used to distinguish the modification records of the same display parameter structure; Type=1; //1 represents the current data block type is 1. Further, the above content shows some screen parameters that need to be saved and the corresponding parameter type definitions, but in the actual software code, different information block data can also be represented by numbers, for example, 1 represents the basic parameter type.

In step 103, all data blocks storing LED display screen parameters are combined for compression processing, and the compressed data is written into a file with a specified suffix and stored in a temporary memory.

For example, after writing different types of LED display parameters into independent data blocks, before saving the LED display parameters in the data block, it is necessary to combine all the data blocks and perform compression processing, and then Write the compressed data information into the file with the specified suffix, and store the file with the specified suffix in the temporary memory for subsequent parameter reading (loading LED display parameters). Wherein, the file with the specified suffix is a file with the suffix ".rcvbp", and the temporary memory is the specified data storage space, that is, the computer file.

It can be understood that the combination of all data block information is a simple copy process, that is, the process of copying all data block information into a continuous memory space, and then compressing the data in the memory space can be It is convenient to save the data, and also saves the storage space of the data.

Fig. 2 is a flowchart according to another method for saving LED display screen parameters shown in Fig. 1, as shown in Fig. 2, the method further includes: step 104-step 105, or, step 104-step 106;

In step 104, the data volume of the LED display screen parameters to be saved is determined.

In step 105, if the amount of data is greater than the preset value, the steps of setting a number of data blocks to be written/read in the form of byte streams and subsequent steps are performed.

In step 106, if the amount of data is less than or equal to the preset threshold, the LED display screen parameters to be saved are compressed and stored in the temporary memory.

For example, in another embodiment disclosed by the present invention, after the LED display screen control system obtains the LED display screen parameters that need to be saved, it also needs to determine the data volume of the LED display screen parameters. When the data of the LED display screen parameters that need to be saved When the amount is large (greater than the preset value), the LED display parameters are written into the data block and compressed after the method described in the above step 102-step 103, and then saved. When the LED display parameter data that needs to be saved When the quantity is not higher than the preset value, directly save the LED display parameters.

It should be noted that in the actual application process, whether to use the above steps 102 to 103 to save the LED display parameters is related to the data volume and information complexity of the LED display parameters. In the disclosed embodiments of the present invention, the The preset value is set to 28KB. When the data volume of the LED display screen parameters is greater than 28KB, the method described in the above step 102-step 103 is used to save the LED display screen parameters.

Fig. 3 is a flow chart of a method for loading LED display screen parameters according to an exemplary embodiment. As shown in Fig. 3, it is applied to a LED display screen control system, and the method includes:

In step 301, the target type of the LED display screen parameters to be loaded is acquired.

For example, when it is necessary to read the parameters of the LED display screen, the LED display screen control system in the disclosed embodiment of the present invention obtains the target type of the LED display screen parameters that need to be loaded according to the loading instruction issued by the staff, so as to Find the corresponding LED display parameters in the temporary memory.

It should be noted that the target type involved in the disclosed embodiments of the present invention is the type of LED display screen parameters that need to be loaded, which is determined according to the loading instruction before loading. The type of LED display screen parameters involved in the above steps 101 to 103 is the type of LED display screen parameters that need to be saved, and the type is determined according to the obtained LED display screen parameters during the saving process. That is to say, the target type in step 301-step 303 may be the same as or different from the type of the LED display parameter in step 101-step 103, which is determined according to the actual situation.

In step 302, a circular search is performed in the temporary memory according to the object type.

In step 303, if there is a target data block corresponding to the target type, the LED display screen parameter information in the target data block is loaded.

Illustratively, in the disclosed embodiments of the present invention, a circular search method is adopted to find the LED display parameters of the target type in the temporary memory. In this way, no matter how the order of the data blocks is set when saving the LED display parameters, loading the LED Each data block will not affect each other in the process of display screen parameters.

Specifically, take reading the gamma jump gray table information data as an example, loop through the parameter file (the file with the specified suffix) to find and compare whether there is data block information of the rpbt_gammaCalibrationTable_delta type, if it exists, load the target data block, if If it does not exist, the data block information of this target type will not be loaded.

Fig. 4 is a flowchart according to another method for loading LED display screen parameters shown in Fig. 3, as shown in Fig. 4, the method also includes:

In step 304, the file with the specified suffix is determined.

In step 305, decompress the compressed data in the file with the specified suffix, and obtain the decompressed data block information.

For example, after determining the target type of the LED display parameters that need to be loaded, it is also necessary to determine the file used to save the LED display parameters, that is, the file with the specified suffix, and the data block in the file with the specified suffix is compressed. Data information. Therefore, first decompress the compressed data information in the file with the specified suffix, obtain the decompressed data block information, and then find out whether there is a target corresponding to the target type from the decompressed data block information by means of circular search data block.

In addition, it can also be understood that if the LED display parameters corresponding to the target type are saved by the method described in step 106 above, when loading the LED display parameters corresponding to the target type, there is no need to execute the file to determine the specified suffix As well as the step of decompressing the data information in the file, you can directly find the corresponding LED display parameters in the temporary memory by means of circular search and load them.
