As described in the background art, in the related art, a single-frame sending and receiving processing method is adopted for processing infrared data, and since infrared data is interfered by infrared signals of the same band in a processing process, such as infrared signals of an infrared touch screen and other external light, if single-frame data for processing is interfered in the processing process, the infrared data for processing cannot be correctly decoded. The invention provides a processing method of infrared data, wherein the same multi-frame data triggered by a remote control key triggering signal is received; combining the data codes and/or the data inverse codes in the data code segments of the multi-frame data in pairs to form a plurality of pairs of decoding combinations; and analyzing the multiple pairs of decoding combinations, wherein if two data in any pair of decoding combinations are the same or are mutually reverse codes, the decoding data is valid decoding data, and otherwise, the decoding data is invalid decoding data. Therefore, the infrared data processing method provided by the invention increases the number of decoding combinations by carrying out multi-frame sending processing on the infrared data, and improves the decoding accuracy of the infrared remote control receiving end and the anti-interference capability in the infrared data processing.
On one hand, in the embodiment of the present application, a processing method for infrared data is provided, where the processing method is applied to an infrared remote control device and includes a sending end for sending infrared data and a receiving end for receiving an infrared signal, and fig. 4 is a schematic flow diagram of the processing method for infrared data provided in the embodiment of the present application.
Step 130 analyzes the multiple pairs of decoding combinations, and if two data in any pair of decoding combinations are the same or are mutually reverse codes, the decoding data is valid decoding data, otherwise, the decoding data is invalid decoding data.
The different analysis methods adopted by different decoding combinations are different, and the specific analysis method is as follows:
if the decoding combination comprises two data codes, if the two data codes are the same, the data codes are effective decoding data; if the decoding combination is a data code and a data inverse code, when the data code and the data inverse code are mutually inverse codes, the data code is effective decoding data; and if the decoding combination comprises two data inverses, and when the two data inverses are the same, the data code corresponding to the data inverses is obtained as effective decoding data.
Preferably, in order to improve the decoding efficiency and save the decoding computation time, the analysis of the decoding combination is performed according to the following analysis steps, and the specific analysis steps are shown in fig. 5.
Taking two frames of data transmission of NEC protocol as an example, the parsing step is specifically described, where the transmission format of two frames of data is shown in fig. 6, each frame of data includes an address code segment and a command code segment, where the same data code segment includes a data code and a data inverse code, the data code segments in the two frames of data transmitted are received, and the data code and the data inverse code of the same data code segment are combined two by two to be combined into a plurality of decoding combinations for parsing.
The address code segment is taken as an example to specifically describe the combination method and the analysis method of the decoding combination, wherein the address segment in the first frame includes the address code A1 and the address code

After the decoding combination is obtained, the decoding combination is analyzed, and in order to improve the decoding work efficiency and optimize the decoding calculation, the decoding combination is preferably analyzed according to the following steps:
first, the decoding combination of the same frame is analyzed, i.e., the decoding combination A1 is analyzed
Or A2
Performing parsing if any one of the decoding combinations is combinedIf the address code and the address bar code in the sequence are mutually bar codes, the A1 or A2 is obtained as effective decoding data, the analysis is successful, the decoding is finished, otherwise, the decoding combination of different frames is analyzed.
In the method for processing two frames of infrared data, the decoding combinations of different frames comprise four decoding combinations: A1A2, A1

Firstly, analyzing a decoding combination containing two address codes, namely analyzing an A1A2 combination, if the address code A1 and the address code A2 are completely the same, acquiring A1 or A2 as effective decoding data, and ending the analysis; otherwise, the decoding combination containing the address code and the address complement is analyzed, namely, A1

In the related art, the processing of the infrared data is to transmit, receive and process a single frame of infrared data, when the infrared data is received, the infrared signal of the same waveband interferes with the received signal, the signal in the single frame of data receives the interference, the unique decoding combination on the same data code segment fails, and the transmitted whole infrared data cannot be decoded correctly.
Compared with a method for processing single-frame infrared data, the method for processing the middle-infrared data by two-frame sending is implemented, when a user performs one-time key operation, the infrared remote control sending end sends the same infrared data by two frames to the receiving end, receives the infrared data sent by the two frames, combines data codes and/or data inverse codes in the data code segment in pairs to form a decoding combination, analyzes the decoding combination and obtains effective decoding data. The processing method can increase the number of combinations used for decoding from 1 group to 6 groups in the related art, and can realize correct decoding as long as any one group of decoding combinations is analyzed correctly. Compared with a one-to-one decoding mode in the related art, the multi-frame sending processing of the infrared data improves the decoding combination number, improves the decoding success rate of the infrared remote control receiving end, and enhances the anti-interference capability of the infrared data in the processing process.
In order to improve the anti-interference capability and the decoding success rate, the invention can carry out three-frame processing on the infrared data, and compared with a two-frame processing mode, the invention can provide more decoding combinations for an infrared remote control receiving end, and has higher decoding success rate and stronger anti-interference capability.

And receiving the data code segments in the transmitted three-frame data, and combining the data codes and the data inverses of the same data segment bit in pairs to form a plurality of decoding combinations for analysis.
The address segment is taken as an example to specifically describe the combination method and the analysis method of the decoding combination, wherein the address code segment in the first frame includes the address code A1 and the address code

And
and analyzing the combination, if the two address anti-codes of one group of decoding combination are completely the same, solving the address code corresponding to the address anti-code as effective decoding data, and finishing the analysis and successfully decoding.
The infrared data is processed by adopting a three-frame processing method, the number of decoding combinations used by a receiving end for obtaining effective decoding data is 15, compared with a two-frame processing method, the number of the decoding combinations is increased by 9, the decoding success rate is improved, and stronger anti-interference capability in infrared data processing, especially the anti-interference capability for decoding at the receiving end, is ensured. Compared with the prior art, the processing method of single-frame data is one-to-one coding and decoding, if one frame of data is interfered at a receiving end, the decoding fails, and the processing method of multiple frames of data is adopted, so that under the condition that one frame of data is interfered, the data of other frames can be analyzed to obtain effective decoding data, and the decoding is successfully carried out.
It should be further noted that, in the present invention, the parsing step of the decoding combination is not unique, and the decoding combination can be randomly parsed, so long as the parsed decoding combination has data in one group that are the same or are mutually opposite, that is, the decoding is successful, and the parsing is completed after the valid decoding data is obtained. In order to improve the analysis efficiency and optimize the decoding calculation time, the analysis steps mentioned in the implementation of the invention are preferably adopted, firstly, the decoding combination of the same frame is analyzed, after all the decoding combinations are analyzed, effective decoding data are not obtained yet, the decoding combinations of different frames are analyzed, two data code combinations, a combination of a data code and a data anti-code and a combination of two data anti-codes are analyzed in sequence, in the process of analyzing the decoding combinations, the effective decoding data can be obtained only if one group of decoding combinations is analyzed correctly, and the decoding is successful.
It should be further noted that, taking the user as an example of performing the key operation, the duration of the key of the user is generally more than 500ms, and the transmission time for transmitting one frame of infrared data is 110ms, which is less than the duration of the key, for the key operation, if four frames of infrared data are transmitted, the total transmission time of multiple frames is 440ms, which is close to the duration of the user operation of 500ms, which is likely to cause an infrared data transmission error, and moreover, the number of transmitted frames is too many, the number of times of combined decoding increases, which inevitably increases the analysis operation time, and greatly reduces the decoding efficiency. Therefore, for executing one-time remote control key operation, a two-frame or three-frame processing mode is preferably adopted, so that the decoding efficiency can be ensured, and the decoding success rate can be improved.
It should be further noted that the multi-frame transmission of the data code segment may be continuous transmission or intermittent transmission, the continuous transmission formats of two frames of data and three frames of data are respectively shown in fig. 6 and 7, the intermittent transmission format of two frames of data is shown in fig. 8, the intermittent transmission format of three frames of data is shown in fig. 9, and a repetition code is transmitted in each frame of data code segment at intervals, so as to reduce the decoding time of the infrared data and improve the decoding efficiency, and a processing method of continuous transmission of multi-frame data is preferentially used for the infrared data.
