Abstract
In order to solve the problem of campus card system recharging in LAN, in this paper we build a cross network one-way transmission channel from the Internet to the LAN, using the image ferry equipment, and design the campus card recharging system on this channel. With ensuring the physical isolation between the Internet and the LAN, users can easily complete the campus card recharging on mobile phone. After testing, the system can almost recharge in real-time, with a delay of less than 2 seconds. The system is stable and has a good using experience. It has strong innovation and popularization.
