Problems solved by technology

When scanning multiple items, occasionally a scanning terminal (with a display screen) will appear to indicate that the scan is successful, but the communication is abnormal, and there are many repeated data items in the communication process
You have to wait for the communication function to resume and scan the product code again, which will cause customers to wait too long and affect the efficiency of cash register
And one device only corresponds to one Android display, so the utilization rate is low
Traditional communication protocols are redundant when dealing with complex transaction logic

[0096] Such as figure 2 As shown, it is a specific flowchart of a synchronous data processing method for scanning terminal communication of the present invention, including the following steps:

[0097] S1: Define the TLCV data format for synchronous data processing, the TLCV data format is specifically:

[0098] T: represents a TAG tag, including a unique identification code TAG and an application TAG, wherein the unique identification code TAG is used to solidify the solidified information in the communication request including the device sn number, operator ID, and operator name, including 8 A fixed item of 1 byte and a version number of 2 bytes; the application TAG is used to mark the data information in the communication request, including order number, discount offer, bill, and commodity information, including 1 byte of data number and a 2-byte version number.

[0099] L: Represents the length of LENGTH, represented by a 2-byte hexadecimal number, used to count the le...

[0131] This embodiment is an embodiment of practical application with specific data corresponding to the first embodiment, and is only used to explain the present invention, not to limit the present invention, as follows:

[0132] Before data communication, it is first necessary to divide a part of the application TAG for storing fixed information TAG, for example: 0x09 (order number), 0x0A (discount discount), 0x0B (whole order discount), 0x0C (bill), 0x 0E (add product information), 0x0F (number of products), 0x01 (userID), 0x02 (SN), 0x03 (userName), etc. 0xA0-0xFF are used to represent the commodity information TAG, and a table corresponding to the barcode of the commodity information and the application TAG is maintained in the database corresponding to the back-end device for management. At the same time, the above table is dynamically maintained. Each application TAG does not always correspond to a barcode of product information. According to the current usage, the barc...

[0306] Such as Figure 6 Shown is a specific structural diagram of a synchronous data processing system for scanning terminal communication of the present invention, including: a TLCV data format definition module 1, a front-end data sending module 2, a back-end data processing module 3, and a front-end data processing module 4;

[0307] The TLCV data format definition module 1 is used to define the TLCV data format for synchronous data processing, and the TLCV data format is specifically:

[0308] T: represents a TAG tag, including a unique identification code TAG and an application TAG, wherein the unique identification code TAG is used to solidify the solidified information in the communication request including the device sn number, operator ID, and operator name, including 8 A fixed item of 1 byte and a version number of 2 bytes; the application TAG is used to mark the data information in the communication request, including order number, discount offer, bill, and commodi...

Abstract

The invention relates to the technical field of synchronous data processing, and provides a synchronous data processing method and system for scanning terminal communication, and the method comprisesthe steps: S1, defining a TLCV data format for synchronous data processing; s2, enabling the scanning terminal to splice the data in the TLCV data format to form a data packet in the TLCV format, andsending the data packet to the back-end device to realize communication with the back-end device; s3, enabling the back-end equipment to respond to the data packet in the TLCV format sent by the scanning terminal and return the data packet to the scanning terminal; and S4, enabling the scanning terminal to process the data packet in the TLCV format. The invention has the advantage of being capableof processing scanning terminal communication in a scene with high communication frequency and high service quality requirements. And when the communication is abnormal, the next commodity code is directly scanned without waiting, and the data which is not synchronized is processed together after the communication function is recovered.

Description

technical field [0001] The invention relates to the technical field of synchronous data processing, in particular to a method and system for synchronous data processing of scanning terminal communication. Background technique [0002] With the rapid development of mobile payment technology, the scanning terminal, as the front-end hardware device of the financial payment system, has become an indispensable part of the transaction process. With the diversified development of financial payment systems, scanning terminals can support more and more functions, and people are increasingly relying on scanning terminals to complete the transaction process. However, as the scanning terminal can support more and more functions, more and more resources are required for data processing on the scanning terminal. Traditional scanning terminal data processing is difficult to complete due to high communication frequency and service quality. demanding scenes. [0003] For example, during th...
