Problems solved by technology
[0002] As one of the automatic identification technologies, two-dimensional codes are widely used in various fields such as logistics and mobile Internet. However, currently used two-dimensional codes such as QR codes and PDF417 codes are all developed by foreign companies or institutions. And institutions have patents related to QR code technology. The reading equipment based on these patented QR codes is relatively expensive. The cost of using these QR codes for Chinese enterprises is relatively high, and they face potential infringement risks, and there are hidden dangers in information security.
[0007] The above-mentioned patents all need to be connected to a PC or a KIOSK self-service machine to process the collected images, which cannot be carried around and is very inconvenient to use

The invention relates to a portable Chinese-sensible code reading machine and a reading method thereof. The reading machine comprises a housing, a display screen, a CMOS camera, a loudspeaker, a switch and a reading circuit. The reading circuit comprises an ARM embedded processor, an NAND memory unit, a FLASH memory, a WIFI module, a 3G module and a USB interface. The ARM embedded processor is respectively connected with the NAND memory unit, the FLASH memory, the WIFI module, the 3G module and the USB interface I / O. The reading method comprises a character database. The database can prevent a system operation speed from being reduced due to a complex coding conversion process, and ensures coding accuracy at the same time. The reading machine and the reading method provided by the invention have the advantages of accurate and rapid Chinese-sensible code reading, high anti-interference capability, high scalability, simplicity, easy use and good portability, thereby being suitable for Chinese-sensible code reading application on multiple occasions.
Description
technical field [0001] The invention belongs to the field of two-dimensional code recognition, and relates to the recognition of Chinese Sensible codes, in particular to a portable Chinese Sensible code reading machine and a reading method thereof. Background technique [0002] As one of the automatic identification technologies, two-dimensional codes are widely used in various fields such as logistics and mobile Internet. However, currently used two-dimensional codes such as QR codes and PDF417 codes are all developed by foreign companies or institutions. And organizations have patents related to QR code technology. The reading equipment based on these patented QR codes is relatively expensive. The cost of using these QR codes for Chinese enterprises is relatively high, and they face potential infringement risks, and there are also hidden dangers in information security. As a two-dimensional code developed by my country with completely independent intellectual property righ...
