Embodiment Construction

[0031] Specific embodiments of the present invention are described with reference to the above drawings.

[0032] Depend on figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As can be seen,

[0033] A. The original data acquisition module captures all the high and low levels of infrared information one by one with a certain sampling accuracy to form an array sequence 1; assuming that the data is listed as AB, CD, CE, CD, CE, CE, CD, CE , CD, CF, AG, CH, AG, CH, AG, CH, AG, CH, form an array sequence Array_A;

[0034] B. The data serialization module analyzes the above array sequence Array_A, separates Array_A into odd and even columns, then analyzes the odd and even columns, and extracts different values ​​in each column to form Array_B (odd), Array_C (even) , then use Array_B (odd), the relative position in the Array_C (even) array to replace the time value in Array_A to generate a new data sequence Array_D;

[0035] in,

[0036] Array_B (odd) arra...

Abstract

Disclosed are an infrared data processing storage method and an infrared remote-control unit. Stored repeating data sections are reduced by means of data arranging, grouping, analyzing, coding and data volumes which are required to be stored are effectively reduced. The infrared remote-control unit applying the method comprises a key operating device, an infrared signal sending and receiving device and an infrared data processing storage device, wherein the infrared data processing storage device comprises a raw data acquisition module, a data serialization module, a data coding scheme analyzing module, a data compression module, a data storage module and a data recovery module. The infrared remote-control unit is capable of effectively reducing the data volumes which are required to be stored, identifying known and unknown infrared formats, identifying novel coding schemes and identifying differences between long keys and short keys; and storage space can be greatly saved, lossless compression of data can be achieved, and production costs can be effectively reduced.

Description

technical field [0001] The invention relates to an electronic information control device, in particular to a method for processing and storing infrared data and an infrared remote controller. Background technique [0002] At present, wireless remote controllers have been used more and more in daily life, bringing great convenience to people. When the infrared remote control commonly used in home appliances processes and stores infrared information codes, due to the variety of infrared code formats, there are more than 500 known types, and there is no uniform style of infrared information codes, resulting in various modulation methods, different data repetition methods, and modulation carrier ranges. very wide. Therefore, to process and restore infrared information data, there are usually two methods at present. One is to intercept all the data one by one, commonly known as hard copy. Although this method can learn any format, it requires a lot of storage space. , and the l...
