Description
Technical Field
The invention belongs to the technical field of two-dimension code scanning, and particularly relates to a code scanning settlement method and device based on a commodity two-dimension code.
Background
The codes of the commodity bar codes follow the principle of uniqueness so as to ensure that the commodity bar codes are not repeated all over the world, namely, one commodity item only has one code, or one code only can identify one commodity item. The commodities with different specifications, different packages, different varieties, different prices and different colors can only use different commodity codes, and the commodity super scanning bar code can read out the corresponding information such as commodity names, prices and the like due to the storage of related information in the commodity super database. When the commodity is over-settled, the bar code is scanned by the scanning equipment, the corresponding code of the bar code is read, and then the corresponding commodity information is automatically read.
The two-dimensional code is a pattern which is distributed on a plane (in a two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is black and white and is alternated and records data symbol information; the concept of 0 and 1 bit stream forming the internal logic base of computer is used ingeniously in coding, several geometric forms correspondent to binary system are used to represent literal numerical information, and the information can be automatically read by means of image input equipment or photoelectric scanning equipment so as to implement automatic information processing.
However, in the conventional business-super system, both the settlement device and the settlement system are only suitable for bar codes, when a scanning gun scans two-dimensional codes of commodities in an off-line state, website text information is read, and the conventional settlement device and the conventional settlement system cannot directly read the two-dimensional codes for settlement.
Disclosure of Invention
The invention aims to provide a code scanning settlement method and device based on a commodity two-dimensional code, aiming at the problems in the prior art.
The first object of the present invention can be achieved by the following technical solutions: a code scanning settlement method based on a commodity two-dimensional code comprises the following steps:
step S1: recognizing the two-dimensional code: scanning the two-dimensional code by a code scanning gun to identify a two-dimensional code text of the commodity;
step S2: and (3) judging and inputting: judging whether a two-dimensional code text is input or not, and executing the step S3 when the input is judged;
and step S3: locking the keyboard: locking the keyboard according to preset time, wherein the preset time for locking the keyboard is 100-300 milliseconds;
and step S4: judging the text: judging whether the text input within the preset time is a commodity two-dimensional code text, wherein the commodity two-dimensional code text comprises a website and a commodity bar code,
if the text is a commodity two-dimensional code text, executing the step S5;

step S5: outputting bar code text: extracting and outputting a bar code text in the commodity two-dimensional code text;
step S6: outputting a text: and outputting the text input within the preset time length.
The working principle of the invention is as follows: the working principle of the code scanning gun is equal to that of keyboard input, the existing code scanning gun can directly enter for input after inputting a text, so that a two-dimensional code text of a commodity read by the code scanning gun cannot be recognized by an existing settlement device or a settlement system, in the scheme, when the code scanning gun scans the barcode or the two-dimensional code, the code scanning gun reads information and converts the information into text input, namely, the text input is input into a computer and returned according to the sequence of symbols, letters or numbers of the text, when a first input symbol or letter is detected by the computer, the keyboard is locked according to a preset duration, and a business super worker cannot input the information by the keyboard, so that the problem that the two-dimensional code of the commodity cannot be recognized or is wrongly recognized due to the fact that the keyboard input is mixed in the code scanning gun input is solved, the read text information cannot be directly input by the return within the time of locking the keyboard, the text input within the preset duration is firstly judged, when the text of the two-dimensional code text of the commodity is judged as the two-dimensional code text of the commodity, the barcode is extracted from the two-dimensional code text, and the barcode is input into the existing settlement device or the settlement system, and the existing settlement device or the settlement system can be directly adapted to the settlement system. The invention enables the existing settlement device or settlement system to be directly suitable for code scanning settlement of the two-dimensional code of the commodity without replacing the existing settlement device or settlement system, thereby saving a large amount of cost.
In the above code scanning settlement method based on the two-dimensional code of the commodity, the barcode of the commodity includes a prefix, a barcode text and a suffix.
In the code scanning settlement method based on the commodity two-dimensional code, the prefix is gtin/, the bar code text is 14-digit digital code, and the suffix is/.
In the above method for clearing and settling the two-dimensional code of the commodity, step S5 includes determining whether the first digit of the text of the barcode is "0",
when the number of the bar code text is 0, removing the number and outputting a twelve-digit coded bar code text;
and when the number of the bar code text is not 0, outputting the fourteen-digit coded bar code text.
In the code scanning settlement method based on the two-dimension code of the commodity, the text of the two-dimension code of the commodity further comprises a batch number, a single number, a production date, an expiration date, a quality guarantee period and an expiration date.
The second object of the present invention can be achieved by the following technical solutions: a two-dimensional code scanning settlement device based on commodities comprises a computer end, a code scanning gun, a keyboard, a display, a server, one or more processors, a memory and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the programs comprise a code scanning settlement method based on the two-dimensional codes of the commodities.
Compared with the prior art, the method has the advantages that the method can be adapted to the conventional merchant super-junction computing device and the conventional settlement system, the settlement device or the settlement system does not need to be replaced, and the cost is saved.
