Embodiment
In conjunction with above-mentioned description of drawings specific embodiment of the present invention.
Can find out by Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6,
A, by the raw data acquisition module with certain sampling precision, the high-low level of infrared information is all caught one by one, form an array sequence one; Tentation data is classified AB, CD, CE, CD, CE, CE, CD, CE, CD, CF, AG, CH, AG, CH, AG, CH, AG, CH as, forms array sequence one Array_A;
B, above-mentioned array sequence one Array_A is analyzed by the data sequence module; Be separated into the odd and even number row to Array_A; Again the odd and even number row are analyzed, extracted different value composition Array_B (very) in every row, Array_C (idol); Use Array_B (very) then, the relative position in Array_C (idol) array replaces the time value among the Array_A to produce a new data sequence Array_D;
Wherein,
Array_B (very) array is classified as: A, C
Therefore the relative position of A is 0, and C is 1
Array_C (idol) array is classified as: B, D, E, F, G, H
Therefore the relative position of B is 0, and D is 1, and E is 2, and F is 3, and G is 4, and H is 5
The Array_D array is classified as: 00,11,12,11,12,12,11,12,11,13,04,15,04,15,04,15,04,15
C, by digital coding mode analysis module the coded system of new data sequence is carried out recursive calculation, analysis meter is calculated non-repeating data section and repeating data section;
Array sequence A rray_D is carried out recursive calculation since second element:
When Array_D array sequence is:
00、11、12、11、12、12、11、12、11、13、04、15、04、15、04、15、04、15
Through top recursive algorithm, but analysis meter calculate data segment 00,11,12,11,12,12,11,12,11,13 and be non-repeating data section, 04,15 is the repeating data section;
D, data segment is carried out compression memory, only need keep once, remove repeating data repeating data by data compressing module;
Know which partly is a repeating data, which partly is non-repeating data, and data compressing module just can only keep once repeating data, removes repeating data with this, reduces memory space; Simultaneously; For the accuracy of restoring data, the data that sample are generally all minimum to take two bytes, after the serializing of second step to data; Each data only keeps once; Only needing increases repeating data or non-repeating data mark, and with regard to reducible data, this also significantly reduces taking memory space.The data of storage only are array sequence two: A, C, B, D, E, F, G, H, 00,11,12,11,12,12,11,12,11,13, K, 04,15, M at last,
E, by the storage of data memory module after externally in the EEPROM, so that use next time compression;
F, by data restoring module the storage data read from the external electric EPROM; A, C, B, D, E, F, G, H, 00,11,12,11,12,12,11,12,11,13, K, 04,15, M; Use initial data to replace sequential value one by one to data sequence 00,11,12,11,12,12,11,12,11,13,04,15; The result is AB, CD, CE, CD, CE, CE, CD, CE, CB, CF, AG, CH; Contrast finds it only is that the repeating data frame number is different with initial data; But we know the data of repeating frame, only need repeatedly increase repeating data just can guarantee with initial data identical, the lossless compress of completion data.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
