摘要
Based on the characteristics of ATM system and the special requirement of financial transaction, an overall design of hardware and software structure of ATM was made. For software structure, the pattern of modules and table? drive is adopted to realize the security of financial transaction and the diagnosis of communication fault. A new method, which is based on the application layer, transport layer and network layer, is used for diagnosing communication fault. Supporting both magnetic card and IC card, the system has been put into use in real financial systems, and has brought about both economic and social effects.
根据ATM系统的特点及金融交易的特殊要求 ,对ATM系统的硬件及软件结构进行了整体设计 .软件上以模块化及表单驱动的方式 ,实现了金融交易的安全处理、通讯故障诊断等功能 ,并就通讯故障诊断提出了一种新的基于网络应用层、传输层、网络层的方法 .该系统可同时支持磁卡和IC卡 ,已应用于实际的金融系统 ,取得了良好的经济效益和社会效益 .
