摘要：

针对目前国内城市轨道交通自动售检票系统国产化程度不高的问题,设计一种面向轨道交通自动售检票应用的纸币接收机系统。该系统整体采用高可靠性结构设计方案提高安全性,减少卡币率。硬件上运用模块化设计,各模块独立的ARM 高性能处理器、高速直流无刷电机和阵列式传感器可保证处理速度,便于产品维护和升级。软件上利用PCA 算法降维,并用欧式距离法建立模板鉴别纸币。测试结果表明,该系统能够快速、准确地鉴别纸币,真币接收率和卡币率指标达到工程化要求,且接收时间提高1 s 以上,解决了轨道交通领域服务密度大、故障率高的问题。

Abstract:

Aiming at the problem of the now high localization degree of China’s urban rail transport Automatic Fare Collection(AFC) system,a rail transport automatic fare collection oriented bill acceptor is designed. The whole structure is of high-reliability so that it can promote the security and reduce jammed banknote. In hardware aspect,it is of modular design which helps product maintenance and update. High performance with ARM processors of every independent module,high-speed brushless DC motor,an array of sensors ensure the processing speed of the system. And software aspect,it uses the PCA dimensionality reduction algorithms and Euclidean distance to build the template. Test result shows that the bill acceptor can discriminate the bill quickly and reliably,and reach the engineering requirements on receiving rate and bill jammed rate. In addition,the receiving speed can be improved by more than 1 s,which solves the problem of big services density,and sensitive failure rate.

Key words: metro transport, automatic fare collection, bill acceptor, accepting rate, bill jammed rate, accepting speed
