Embodiment 1

[0048] An OID code set applied in the field of audio reading of publications, the OID code set includes 65536 codes, and the code numbers are 0 to 65535. Using these 65536 codes to represent information on tens of thousands of different publications will obviously cause Different information is represented by the same code, so there will be recognition confusion, such as figure 1 Shown, so the present invention has designed following method:

[0049] Extracting the sequence number in this OID code set is 61440~63487, a total of 2048 codes form the first OID code subset, and the codes in this first OID code subset are used to represent the name information (the present invention names this first OID code subset The OID code of is the book code, the same below);

[0050] Extract the serial number in the OID code set as 0~59999, a total of 60000 codes form the second OID code subset, and the codes in the second OID code subset are used to represent the content information of the...

Embodiment 2

[0054] The difference from Embodiment 1 is that the book code in this embodiment uses OID codes with serial numbers 52200-52679, and the content codes use OID codes with serial numbers 52900-53999. The specific methods are as follows:

[0055] Extracting the serial numbers in the OID code set is 52200-52679, a total of 480 codes form a first OID code subset used to represent name information;

[0056] Extracting the sequence numbers in the OID code set is 52900-53999, a total of 1100 codes form the second OID code subset used to represent the content information in the printed matter;

[0057] The name is the catalog of printed matter content, so by using these 1580 codes, we can use them to represent 1100×480=528,000 content information. Much larger than the number of 1580 codes. Although the OID codes used to represent the content information in printed materials with different names may be the same, because the OID codes used to represent the names are different, even the ...

Embodiment 3

[0060] With the gradual increase in the number of publications, the number of printed materials with different names is far more than 60,000, so in order to avoid the situation that the book code set is not enough, such as figure 2 As shown, this embodiment adds the following steps on the basis of the above-mentioned embodiment 1 or embodiment 2:

[0061] Extracting the serial number in this OID code set is 60000~61439, a total of 1400 codes form the third OID code subset, and the OID code in the third OID code subset is used to represent the publishing house information (the present invention names the third OID code The OID codes in the subset are unit codes, the same below), because a publishing house can publish many kinds of printed materials with different names, so the publishing house is the root directory of the name, so use these 1400 codes for representing the information of the publishing house With 2048 book codes, 2048*1400=2867200 kinds of different printed mat...

Abstract

The present invention belongs to the technique field of information management, and relates to a method for expanding the information quantity of the print content characterized by the Optical Identification (OID) code. The method includes: extracting multiple OID codes from an OID code set to comprise a first OID code subset; using the OID codes in the first OID code subset to characterize the name information of the print; extracting multiple OID codes from the OID code set to comprise a second OID code subset; using the OID codes in the second OID code subset to characterize the content information of the print; the name information is the catalogue of the content information, and the first OID code subset and the second OID code subset is disjoint. The present invention expands the information quantity of the print content characterized by the OID code, and thus the information quantity of the print content can be characterized is greatly increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of information management, and relates to a method for expanding OID codes to represent the content information of printed matter. 【Background technique】 [0002] Point-reading products emerged with the development of point-reading code technology. The key to point-reading technology is OID (Optical Identification) codes and point-reading pens that can recognize OID codes. OID is a two-dimensional optical identification code, which can identify different content through different combinations of codes. The actual size of these codes is very small, and the area occupied by each code on the printed matter is about 1.3mm 2 , each code is composed of several small dots, and the distribution positions of the multiple small dots of each code are different, and the coded information expressed is also different. The distribution position of the multiple small dots of each code can be identified by the optical ide...
