Description
Technical field
The utility model belongs to pick-up unit field, especially a kind of intelligent barcode automatic tester.
Background technology
Along with the development of information age, bar code, as a kind of automatic identification technology, with the advantage that it is economic, practical, obtains very large application in each production management field.Bar code has become " I.D. " of " common language " in international trade and commodity in the world.Bar code is one group of width difference, chequered with black and white bar empty graphic, and it utilizes the difference of the change of bar, empty size and the empty dichroic optica characteristic of bar to carry out beared information, realizes automatically identifying and automatic data acquisition.More external manufacturer production bar code printing product checkout equipments at present, bar code detector is promoted to China by part foreign vendor, but the detector of import has problems, and one is price, two is due to region restriction, and three is that the precision that some instrument provides is not inconsistent with actual test.In addition, the detector performing " scanning pattern reflectance curve " analytic approach in international state-of-the-art technology standard and China's newest standards is little.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of intelligent barcode automatic tester, solves and performs international newest standards and China's latest national standards how simultaneously, makes detector automatically identify the problem that Chinese and English operates.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of intelligent barcode automatic tester, be made up of CCD scanner, photoelectric commutator, USB interface, DC/DC converter, 2440 core boards, display interface device, liquid crystal display, power supply, power supply switch circuit, described CCD scanner is connected with photoelectric commutator; Described photoelectric commutator, DC/DC converter are connected with USB interface respectively; Described USB interface is connected with 2440 core boards; 2440 described core boards are connected with display interface device; Described display interface device is connected with liquid crystal display; Described power supply is connected with power supply switch circuit; Described power supply switch circuit is connected with DC/DC converter.
And described USB interface can connect USB flash disk.
And described liquid crystal display has the LCDs of Chinese and English mixed display.
And described liquid crystal display is provided with instrumental keyboard.
Advantage of the present utility model and good effect are:
1, the utility model intelligent barcode detector adopts Chinese and English operation interface, from forward and reverse direction scan bar code symbol, can automatically differentiate the code system being read bar code.
2, the utility model liquid crystal display is provided with instrumental keyboard, handled easily, achieves the design of hommization more.
3, the utility model intelligent barcode detector can utilize powered battery and external power supply to power, and ensure that the stable use of instrument.
Accompanying drawing explanation
Fig. 1 is the utility model anatomical connectivity block diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
As shown in Figure 1, a kind of intelligent barcode automatic tester described in the utility model, be made up of CCD scanner, photoelectric commutator, USB interface, DC/DC converter, 2440 core boards, display interface device, liquid crystal display, power supply, power supply switch circuit, described CCD scanner is connected with photoelectric commutator; Described photoelectric commutator, DC/DC converter are connected with USB interface respectively; Described USB interface is connected with 2440 core boards; 2440 described core boards are connected with display interface device; Described display interface device is connected with liquid crystal display; Described power supply is connected with power supply switch circuit; Described power supply switch circuit is connected with DC/DC converter.
During scanning, the light that light source sends is radiated at bar code symbol on the surface, is reflected by bar code symbol, and reflected light is incident upon on photoelectric commutator by the optical system of CCD scanner, is transformed into electric signal.In scanning process, intensity of reflected light changes with the difference of each bar/empty reflectivity, and the size of electric signal also changes thereupon, and the value of electric signal is directly proportional to reflectivity.Signal is connected to 2440 core boards by USB interface after photoelectric commutator conversion, and 2440 core boards calculate reflectivity and size, the accordingly decoding of each bar/sky according to the size of numerical value.Simultaneously according to the regulation about bar code standard, measured value is analyzed, judges, provide the evaluation result to tested bar code symbol printing quality.This evaluation result is connected in liquid crystal display by display interface device.Power supply through power supply switch circuit and DC/DC converter for instrument provides burning voltage.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model is not limited to the embodiment described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
