With the development of computer science, the demand for the security of information transmission in communication field is further increasing, especially in some fields involving important secrets. Since the two-dimensional code can achieve absolute one-way transmission, the file transmission system based on two-dimensional code begins to enter the public's sight. However, this system can not feedback the transmission status, so it is a one-way, open-loop communication system. When the transmission file is large and the working environment is complex, the success rate can not be effectively guaranteed. This paper deeply analyzes the file transmission system based on QR code, proposes a multiple transmission strategy to improve the success rate of file transmission, and designs experimental analysis to verify them. The experimental results show that the accurate and fast transmission of large files can be achieved by selecting the appropriate QR code capacity and adopting the appropriate multiple transmission strategy.
