Abstract

The invention discloses a bar-code scanner adopting an audio interface. The bar-code scanner comprises a scanning module used for scanning a bar code; a coding module used for converting the bar codeinformation into binary data; a data temporary storage module used for storing the binary data output by the coding module; an encapsulation module used for packing and encapsulating the binary data;a sending module connected with an audio output line in the audio interface and used for sending the bar code information to an intelligent device; a filtering module arranged between the sending module and the intelligent device and used for carrying out filtering on the communication data; and a correction module connected with an audio input line in the audio interface and used for reading barcode information from the intelligent device, carrying out comparison on the bar code information with the bar code information stored in the data temporary storage module and carrying out correctionon filtering parameters of the filtering module according to the comparison result. The bar-code scanner adopting the audio interface and the method thereof can improve the defects in the prior art, realize connection with the bar-code scanner through the audio interface, and realize a fast barcode scanning and identification process.

Description

technical field [0001] The invention relates to the technical field of intelligent equipment, in particular to a barcode scanner using an audio interface and a communication method thereof. Background technique [0002] With the development of mobile smart devices, devices such as smartphones and tablets now have higher and higher processing capabilities. Existing barcode scanners set their own computing CPU to send the scanned and processed data to the smart device. This design is actually a waste of the processing power of the smart device's own processor. In the prior art, there have been devices that are externally connected to RFID card readers through an audio interface. However, in actual use, due to the limitation of data transmission speed and processing speed, it is inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a barcode scanner using an audio interface and a communication met...
