铁路客票系统已在全国车站推广多年，但铁路客运到站补票业务却一直采用人工的计算方法，业务操作和信息维护都很复杂，信息化程度低。为改善铁路客运车站到站补票业务的落后信息化现状，充分利用现有的客票系统网络和应用资源，本文将车站补票系统作为客票系统业务延伸，弥补了客票系统在车站补票领域的空白，完备了客票系统对铁路旅客运输统计分析中的数据来源。提出了车站出站口补票系统的总体结构、网络结构、数据资源及结构，设计了系统主要功能和实现流程，建立了补票系统业务中的事由自动推算和票价自动计算模型。本文开发的客运车站补票系统已投入运营，现场应用效果良好。

Design and Realization of the Pay-upon-arrival Service System for Railway Passenger Transportation

Railway Ticketing and Reservation System (TRS) has been promoted in the railway stations all over the country for several years, but their pay-upon-arrival business still uses manual computing method. Both business operation and information maintenance are complex and the extent of informationization is low. In order to improve the lag information status of pay-upon-arrival business of railway passenger transport station, sufficiently utilize the network and application resources of current TRS, this document views the pay-upon-arrival system as extension of TRS, fills up the blank of pay-upon-arrival area in TRS, complete the data source of TRS for statistics and analysis of railway passenger transportation. It presents the overall, network and data-resource architectures of the service at the exits of the stations, designs the main features and realization process, and constructs the models for automatic note-reckoning and price-calculation. System based on this document has been put into operation in several stations and is well applied in the scene.
