Description
Technical field
The utility model relates to a kind of acquisition system, particularly relates to a kind of data acquisition system (DAS) of bar code.
Background technology
Barcode technology is the most ripe in automatic identification technology, is also most widely used general and the most successful technology; Barcode technology is data acquisition fast and accurately, data inputting provides effectively, reliable means, he and computing machine, network communication etc. together form the basis of modern commerce robotization, bar code symbol makes easily, scan operation is simple, information acquisition speed is fast, and information acquisition amount is large, and device structure is simple, with low cost, therefore this technology is widely used in very to technical field;
Multiple secret note that width does not wait by bar code and blank, according to the arrangement of certain coding rule, in order to express the figure identifier of one group of information; Common bar code is the pattern of parallel lines that the secret note (abbreviation bar) that differed greatly by reflectivity and informal voucher (being called for short empty) are lined up; Bar code can mark many information such as the producing country of article, manufacturing firm, trade name, date of manufacture, book classification number, mail start-stop place, classification, date, is thus all widely used in many fields such as commodity circulation, taking care of books, postal management, banking systems;
Bar code scanner common on the market sends data to PC by USB interface, and such bar code scanner carries just not very convenient;
Bar code is seen everywhere in life, and the recognition technology of bar code is also widely used in many fields; We are devoted to the research of identification to bar code information, process, serial transmission, display and storage, and develop low cost, portable, visual Collection System of Barcode Data.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of Collection System of Barcode Data, and this system is easy to carry, and visualization is high;
For achieving the above object, the technical scheme that the utility model is taked is:

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, a kind of Collection System of Barcode Data, comprises bar code scan module, power supply module, single-chip microcomputer, LCD data disaply moudle, data memory module and minimum system; Described power supply module is electrically connected with bar code scan module; Described bar code scan module is electrically connected with single-chip microcomputer; Described single-chip microcomputer is also electrically connected with LCD data disaply moudle, data memory module, minimum system respectively;
Described bar code scan module is optically-coupled bar code scan module, and its model is MCR12; Why adopt the scan module of this model, mainly utilize the photoelectric coupling principle of this module, imaging is carried out to bar code printing pattern, then decoding; The inner structure of bar code scan module as shown in Figure 2, after turn on-switch 8, luminous secondary body 7 sends radiance, light 6 is through the first lens 5, be irradiated to bar code, reflected light on photoelectric commutator 3, converts corresponding 0,1 digital signal by amplification and rectification circuit 1 through the second lens 4 focusing illumination, decoding scheme 2 converts thereof into corresponding numeral, character breath according to corresponding cryptoprinciple, gives LCD liquid crystal display show by output interface 9; Complete bar code and debate the process read;
In addition, the bar code scan module of this model is communicated by RS232 serial ports with single-chip microcomputer, realizes the direct connection of data;
The model of described single-chip microcomputer is AT89C51; Minimum system comprises crystal oscillating circuit and reset circuit; Received the data of bar code scanner module transmission by the serial ports of single-chip microcomputer, read into single-chip microcomputer, just can store data, show;
Described data memory module is provided with AT24C02 chip; This part stores the bar code data that single-chip microcomputer receives, and realizes power failure data and do not lose, and facilitates the follow-up use to data; Adopt AT24C02 chip, pass through I
2c communication protocol and single chip communication, realize the storage to scanning the barcode data obtained;
LCD data show, and this part is shown the bar code data that single-chip microcomputer obtains by liquid crystal display, and the concrete mode of liquid crystal 1602 serial that adopts is connected with single-chip microcomputer;
The utility model adopts RSR232 interface, by serial ports, bar code data is sent to single-chip microcomputer, directly shows in LCD liquid crystal display, compared with showing, have the advantages such as cost is low, portable with traditional PC;
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, all drop within protection domain of the present utility model.
