Method compatible with multiple sets of setting codes and code scanning equipment

Abstract

The invention relates to a method compatible with multiple sets of setting codes and code scanning equipment. A mapping relationship is established between a target bar code and a native setting code;the target bar code has the same function as the native setting code; according to the technical scheme, one setting item can be set by a plurality of bar codes, so that one code scanning device canbe compatible with a plurality of sets of setting codes, the defect that one code scanning device can only be set by one set of setting codes in the prior art is overcome, and the adaptability of thecode scanning device in industrial application with complex and changeable requirements is improved.

Description

technical field [0001] The invention relates to the field of bar code scanning, in particular to a design and use method of a setting code and a system thereof. Background technique [0002] The scanning device is a hardware device that converts the image of a one-dimensional barcode or two-dimensional barcode into a string. In order to simplify the hardware structure and reduce the cost of the product, the scanning device is generally not added by adding buttons or switches. To set the function, the function setting is realized by using the scanning function of the scanning device itself and scanning specific barcodes. Since these specific barcodes contain information that can configure the scanning device, they are generally called "setting codes". The setting code itself is an image, which represents a string of character information in the form of a one-dimensional barcode. This string represents the setting instruction that can configure the function of the scanning dev...

Problems solved by technology

[0003] At present, the design rules of the setting instructions represented by the setting codes of different brands on the market are not the same. Since there is no unified standard, each scanning device only supports the setting codes of one design rule. In actual use in the industry, Sometimes there will be some troublesome situations: for example, installing multiple scanners of a certain brand on a factory line, when one of them fails or some stations need to replace devices with different performances, in order to facilitate unified configuration and management, generally Only equipment of the same brand will be replaced, which limits the scope of procurement to a certain extent, which is not conducive to cost control; another example is that a certain brand of code scanning equipment or scanning modules has been integrated on some large equipment, which is inconvenient to disassemble Or it cannot be disassembled. When it is necessary to replace a different brand of scanning equipment or scanning module due to various reasons, the current equipment can only be scrapped, which causes a waste of resources and funds.
