一种LED异步屏信息显示系统的构建方法

根据人们购票的实际需要,专门为火车站票务信息显示架构了一整套的设计方案:从硬件结构的原理设计、模型建立,型材选取,最后到软件的功能实现,经过实际运行检验,完全实现了当初的设想。实现方法是在各售票窗口上方挂LED大显示屏,显示内容为未来几天开往全国各地的车次信息,包括日期、始发、终到、软硬座及软硬卧的有无信息等等。通过上位机软件实现对数据的采集、拆分和按预定格式显示等一系列操作。上位机软件用DELPHI语言编写。

A Way to Construct the LED Asynchronous Screen Ticket Information Display System

Based on the actual needs of people's buying tickets, this article makes a set of design options for the railway station about the display of ticket information. The framework including the follows: the principle of hardware design, model structure, material selection and the final realization of the software. The actual application fulfills the original vision. The concrete method is to hang large LED screen in the top of the ticket window to display the ticket information of the next few days, including the date, origin, end, soft, hard and soft Hard Sleeper at the availability of information, and so on. The data collection, separation, data display according to the format and a series of operations are implemented by PC software. PC software used to prepare with DELPHI language.
