Description

A kind of pair of bar code scan unit and scan method and application
Technical field
The present invention relates to a kind of bar code scanning unit and scan method thereof and application, particularly a kind of can single pass two bar code scans unit that device adopted of at least two bar codes of recognition.
Background technology
At present, have some bar code scanners on the market, they can distinguish the information of bar code through scanning bar code.These bar code scanners are made up of four parts basically, comprise image acquisition component, control assembly, data processor and output block.These bar code scanners can only be discerned and read a bar code information in the single pass process.Though this type scanister has identity preferably,, no longer simple a kind of bar code in the commodity packaging along with the continuous development of digital technology, network technology; In the present most commodity packaging; Except commodity bar code, often simultaneously also with logistics code, security code, internal code or the like bar code, if adopt existing bar code scanning equipment to gather these information in the commodity packaging one by one; Each part commodity all will be through repeatedly scanning, inefficiency.
Summary of the invention
The objective of the invention is provides a kind of pair of bar code scan unit and scan method and application to above-mentioned weak point, makes that through using this element scanister can at least two bar codes of single pass, improves the efficient of bar code scanning recognition.
A kind of pair of bar code scan unit and scan method thereof and application take following technical scheme to realize: a kind of pair of bar code scan unit comprises image acquisition component, control assembly, data processor and output block; Image acquisition component is connected with data processor and control assembly, and data processor is connected with output block and control assembly; Have the bar code cache module in the data processor, be used for the scanning result of temporary two bar codes; In control assembly, have bar code comparison filter logic module, the bar code information that is used for data processing section is parsed and the bar code data of bar code cache module are compared.
The storage space of described bar code cache module is greater than the 64K byte.
A kind of pair of bar code scan unit can be installed on smart mobile phone, mobile data collecting device and the POS machine and use.
When described bar code was compared the work of filter logic module, if the bar code data in the bar code cache module is empty, bar code comparison filter logic module obtained bar code data with the data processing parsing and is stored in the bar code cache module; If had bar code data in the bar code cache module; Judge then whether existing bar code data repeats in bar code data that comparison parses and the bar code cache module; If repeat; Then give up the bar code data that parses,, then the bar code data that parses is saved in the bar code cache module if there is not repetition; When the bar code quantity of preserving in the bar code cache module equals 2; Control assembly will be controlled image acquisition component and stop bar code scan; Control output block simultaneously two bar codes in the buffer memory are outwards exported, and with the storage space zero clearing in the bar code cache module.
The scan method of a kind of pair of bar code scan unit comprises the steps:
1) but two bar codes on the bar code carrier are placed the zone of image acquisition component panoramic scanning;
2) bar code image in the continuous asynchronous collecting scanning area of image acquisition component, and convert the bar code image that collects to view data, the image data transmission after will changing then is to data processor;
3) data processor is continuously asynchronous to step 2) in the view data that obtains utilize the bar code analytical tool to carry out data parsing, and obtain one of them bar code data;
4) bar code data that will resolve of data processor sends to control assembly, and the bar code comparison filter logic module in the control assembly is compared the data in described bar code data and the bar code cache module; If the bar code information in the bar code cache module is empty, bar code comparison filter logic module is resolved the bar code data that obtains with data processing and is kept in the bar code cache module; If had bar code data in the bar code cache module; Judge then whether existing bar code information repeats in bar code data that comparison parses and the bar code cache module; If repeat; Then give up the bar code data that parses,, then the bar code data that parses is saved in the bar code cache module if there is not repetition;
The quantity of the bar code data of 5) having preserved in the bar code comparison filter logic module check bar code cache module if deposited 2 different bar code datas in the bar code cache module in, then changes step 6) over to, otherwise returns step 2);
6) data processor is sent to output block with the bar code data of preserving; Control assembly control image acquisition component stops bar code scan; Control output block simultaneously two bar codes in the bar code cache module are outwards exported, and with the storage space zero clearing in the bar code cache module.
Described bar code carrier is packing box, packaging bag and Commercial goods labels etc.
Described bar code analytical tool is the Bit-Matrix function of increasing income.
In described step 4),, then provide the image or the character property prompting of auditory tone cues, vibration prompt or human-computer interaction interface if the bar code data that parses is saved in the bar code cache module.
In described step 4), deposit the bar code data in the bar code cache module in, be sent to output block, under the control of output block, this bar code data is write in External memory equipment or the database.
A kind of pair of bar code scan unit and scan method thereof are applied in commodity counterfeit prevention, logistics control and the business administration.For example; In the Comodity anti-fake system of the permanent peace side of Nanjing China skill company limited of Boke and Jiangsu heart Science and Technology Ltd. cooperation research and development; Adopt 13 bar code and 13 commodity counterfeit prevention sign indicating number in the commodity external packing, can realize the unified anti-fake code of global commodity and the purpose of anti-fake certificate.If adopt general bar code collecting device, every each collection twice of commodity, inefficiency.After the scanister of the two bar code scan unit of the present invention had been installed in employing, the bar code information and the security code information of commodity only needed run-down, accelerate the speed of merchandise news acquisition process and authentication greatly.
Advantage of the present invention: the present invention can be applied in the existing scanister, fully compatible existing scanister and running software flow process; Combination through bar code comparison filter logic module and bar code cache module makes bar code scanner can realize many bar code scans.Improved scan efficiency effectively, practiced thrift manpower and materials,, improved enterprise competitiveness for logistics management, merchandise sales etc. gains time.
