Abstract

The invention relates to a bar code processing circuit supporting multiple communication protocols. The circuit comprises a camera module, a main controller, a power supply module, an interface conversion module, an interface configuration module and an output interface. The power supply module supplies power to other modules in the bar code processing circuit. The camera module is used for transmitting acquired images to the main controller. The main controller performs a decoding attempt. The interface configuration module is used for transmitting a decoded result to the interface conversionmodule. The interface conversion module is used for converting the decoded result into a plurality of protocol data, each protocol data conforms to an interface protocol, and the interface configuration module is configured to enable one protocol data to be transmitted outwards through the output interface. The bar code processing circuit greatly improves the flexibility and universality of the bar code processing circuit.

Description

technical field [0001] The invention relates to a barcode processing circuit and a barcode reading module supporting multiple communication protocols, and belongs to the technical field of barcode reading. Background technique [0002] Existing barcode reading devices generally adopt a customized development model, and each user has different requirements for device interfaces. Some barcode reading devices require RS232 interface protocol to transmit data, and some barcode reading devices require Wiegand protocol to transmit data. Therefore, it is necessary to redevelop the interface circuit for different users, the barcode reading equipment has poor versatility, and increases the development cost and development cycle. [0003] The announcement number is CN 207623974 U's patent "A Multi-Interface Protocol Converter", which has four interfaces: USB interface, TTL interface, 485 / 422 interface, and RS232 interface, as well as USB to TTL module and TTL / 485 / 422 isolation module ...
