Abstract

Based on a hierarchical network design model, a mobile payment network architecture design scheme for the Automatic Fare Collection (AFC) system of urban rail transit from subway terminal equipment to subway mobile payment platform is proposed. This paper uses VLAN technology and Trunk mode to construct the AFC mobile payment network, and takes Line 3 subway as an example to describe the key design of adding a three-layer switch during using communication fiber for self-organizing ring network. The network redundancy design method is used to improve the redundancy of the mobile payment network, and the communication between AFC terminal equipment and the mobile payment platform is realized. Aiming at the characteristics of the subway AFC mobile payment network architecture, common network fault analysis and handling methods for mobile payment in AFC are given.
