Method and device for sending dot matrix pattern recognition signal based on wireless module

Abstract

The invention provides a method for sending raster graphics on the basis of a wireless module to identify signals. The method includes the steps that whether a receiving terminal capable of being matched with a 2.4 G sending module exists or not is judged; images of the raster graphics are acquired and fed back; the images of the raster graphics are processed so as to make the gray level reach the preset range; whether the raster graphics in the images of the raster graphics meet preset parameters of images of the raster graphics or not is judged; the raster graphics are analyzed and subjected to CRC check so as to form code values; the code values are extracted and made to generate an enciphered data package; the enciphered data package is sent. The device for implementation of the method includes the 2.4 G sending module, a matching module, an infrared reading module, an image processing module, a raster graphic parameter judging module, a raster graphic parameter analyzing module, a CRC check module, an extracting module and an enciphering module. According to the method and device, the 2.4 G wireless sending module is adopted to directly send the enciphered data package corresponding to the raster graphics, and therefore the receiving terminal can accurately receive the enciphered data package.

Description

technical field [0001] The invention relates to a signal sending method, in particular to a method and a device for sending a dot matrix pattern recognition signal based on a wireless module. Background technique [0002] At present, the transmission method with anti-counterfeiting information is generally based on the RFID radio frequency transmission method. After the anti-counterfeiting information is generated into an RFID electronic tag, it is sent through a wireless transmission device. However, since the anti-counterfeiting identification information needs to be subjected to subsequent graphic processing and encryption processing after it is acquired, the anti-counterfeiting identification information after multiple processing finally forms a high-frequency encrypted data packet. Due to the particularity of the high-frequency encrypted data packet , if it is converted into an RFID electronic tag and then sent, it may cause the receiving end to be unable to accurately ...

However, since the anti-counterfeiting identification information needs to be subjected to subsequent graphic processing and encryption processing after it is acquired, the anti-counterfeiting identification information after multiple processing finally forms a high-frequency encrypted data packet. Due to the particularity of the high-frequency encrypted data packet , if it is converted into an RFID electronic tag and then sent, the receiving end may not be able to receive the high-frequency encrypted data packet accurately and completely, resulting in poor data transmission
