First of all, about the definition of "intelligence":
The definition of "intelligence" in the scientific community is that an existence can be regarded as an "intelligent" existence with the functions of reasoning and memory. Among them, there are two elements: one is memory function, and the other is reasoning function. Of course, reasoning can only be based on memory. Memory function is the basis of intelligence. For example, the popular "memory metal material" can become.
Second, the CD management cabinet:
It is an object to manage optical discs, with no memory characteristics and no' intelligence'. When we make it have certain memory function and reasoning function through technology, it realizes' intelligence'. Our company (Beijing Sunshine Synchronization Technology Development Co., Ltd.) developed the independent intellectual property product [Intelligent CD Management Library (Cabinet) System] to make our CD management cabinet:
III. Main technical features of [Intelligent CD Management Cabinet]:
65438+ Therefore, it has intelligent functions.
Here, a concept should be clarified, that is, the system should remember the spatial location address of the "CD", not the location address of the "CD box", because the goal of the product is to manage the CD, not the "CD box". Managing the "CD box" is an indirect management method, which will bring many problems to future users. For example, in the library, when students borrow CDs, they will return them for some reason. Especially the information discs of confidential/confidential/important units, the consequences are unimaginable. Our patented product is to store/manage "compact discs" instead of "compact disc boxes". This is the real "CD management". This technology will be mentioned below.
2. Definition of optical disc recognition: In thousands of optical discs, to remember the spatial position of optical discs, it is necessary to extract and remember the characteristics of each optical disc. This means to mention the feature extraction method for optical discs, just like the extraction of human fingerprints/red films. Our products are based on the method of extracting the "fingerprint" of optical discs, that is, using the "optical drive" on each computer as the optical disc identification device, and automatically extracting the optical discs whenever they are put into storage. At present, advanced management methods. This method of memorizing optical disks has more advantages than the "optical disk box management" mentioned above. For example; The returned CD can be judged to be true and false, which ensures that there will be no problems such as misplacing/package switching caused by "CD box management" and no secondary confusion of CDs.
Fourthly, the comparative study of "CD management" based on CD "fingerprint" and "CD box management" based on CD box barcode.
We know that the identification of every individual in the world is becoming more and more important. Its importance will not be mentioned here. I'm sure everyone knows that. We only look at the development of people's identification methods. From the simplest recognition by memory, to the identification of identity cards, to the development of human fingerprints, and then to the development of iris recognition. More and more accurate, because the features extracted by the latter are unique. In the final analysis, there are two kinds of identification. First, indirect identification, visual inspection, identity cards and so on all belong to this category. Reputation is the biggest problem. Second, direct identification, such as fingerprint and iris, has high accuracy and is the most widely used method in modern technology.
After the above problems are clarified, it is not difficult for you to have a clear understanding and judgment on "CD management" and "CD box management".
Fifth, "CD management" has more advantages and development space than "CD box management" products:
Because the CD-ROM drive is used to identify the fingerprint of the CD-ROM, the computer can automatically record/back up/mirror other information of the CD-ROM while reading the fingerprint of the CD-ROM, which will bring great benefits to the information management of the CD-ROM. In addition, it also provides technical support for direct transmission/copying/* * sharing of CD materials in the future. However, the "CD-ROM box management" mode with bar code attached to the "CD-ROM box" does not have the above advantages. You can only enter some information manually. This is not the direction of development. It is a main mode of CD management-"supermarket goods management" mode.
Six? Classification from "warehousing" mode:
1,? Stick a bar code on the CD box. Make a table corresponding to the bar code position, and manually enter some information about this CD. For future reference. Because the information is entered manually, the amount of information is very small. It can't be too big
2,? Stick a number on the CD box. Make a table corresponding to the number position and manually enter some information about this CD. For future reference. Because the information is entered manually, the amount of information is very small. It can't be too big
3,? Scan the CD directly and read the CD fingerprint. Under the corresponding fingerprint, the user can automatically record the information of the CD. Can be more or less.
Analysis:
Item 1, Item 2 is put into storage through the record "CD box". Not the disc itself. Therefore, it brings great hidden dangers to future management. That is, the computer only recognizes "CD boxes". Never mind what's inside/whether it's true or not. In other words, even if you put "pancakes" in it, the computer won't care. Only recognize the "box". I don't know what's in it. The second way, which lacks technical content and security, is no different from a simple CD shelf. When there are a large number of CDs, it is inevitable that there will be confusion because there is no "identification device". Not available.
The third warehousing method. Is to extract the unique fingerprints of each CD. In addition, the required information can be automatically recorded according to the needs of users. More processing can be performed at the same time. Such as mirroring/releasing of optical discs. This greatly expands the use and development space of the system.
Seven, from the classification of "library":
Number one? One way:? Scan the optical disc box with bar code with a bar code gun. The computer gives the physical location of the CD box. The user puts the CD box in this position.
2,? I'll put the CD in the library. Put it in the optical area to read the fingerprint of the CD itself. Because the fingerprint has been recorded in the database, it is unique. The positioning of the software control cabinet is clear (that is, in a fixed position, the indicator lights up, and when multiple cabinets are connected, the cabinet number is displayed on the computer display screen).
Analysis:
1 warehouse return method. In the vernacular, it means only recognizing the "box" and not "what's inside". This will cause, management confusion. For example, this system is used in the library. Students borrow one CD and return it, and another CD. The result is the same. Go back to the library. However, at this point, the CD in the library has been' switched'. Then tons and so on. A few years later. The disk in the library is completely different from the CD burned by the computer. Without evidence, it can't be retrieved at all. What's more, such a system manages very important confidential CD-ROM materials of units with high security level. The consequences are very serious.
The second way to return books. Security issues, errors, and associated reader management issues cannot be resolved. It has nothing to do with "intelligent management". Belonging to a simple stacked optical disc rack. Readers can understand.
Therefore, the real intelligent management mode is to adopt the method of "CD identification fingerprint returning to the database".
Eight, from the way the CD is placed in the cabinet:
The cabinets were cut off one by one. Cut off the positioning light. Some use the moving counterpoint method, and some use the fixed cutting method. Anyway, it's all cut. Used to put the "CD box".
A fixed/pull-down/dust-proof disk bin made by seiko. It is fixed on the cabinet. There is a positioning indicator light under each box. So it is called: one plate, one warehouse and one positioning. There will never be disc confusion.
Analysis: 1, occupying space. Adopt "cut-off" CD box. Due to the thickness of the cut (too thin to weld) plus the thickness of the CD case. The number of discs that can be placed in a unit volume will be less. However, when the fixed disk box mode is adopted, a lot of wasted space can be obtained. Therefore, in unit volume, the number of discs placed by the latter is far greater than that of the former. At the same time, it also reduces the management cost for users. It is said that some manufacturers, in order to improve the capacity of optical discs per unit volume. Actually, there are two CDs in a CD box. Yes, this can quickly increase the capacity, but it will bring trouble, wear and even damage to the CD.
2. Why do you say that? First of all, two CDs were forcibly placed in the CD box where one CD was originally placed. "CD crowded" is definitely easy to damage. Secondly, two pieces can be put in a box, and only one box can be put in one cutting. Therefore, when leaving the warehouse, the two disks are set in one position. ? Which one does the user want? Still rummaging through the box. What is certain is that. This action, which cannot accurately judge which disk to turn over immediately, virtually causes the probability of disk damage.
