课程设计-基于PLC的地铁自动售票机控制系统设计

基于 PLC 的地铁自动售票机控制系统设计摘 要：随着社会经济的迅速进展，地铁列车也开始广泛出现于人们视野中。地铁列车具有形式速度快，价格低廉的优势，因此在各大城市中得到了较快的进展。PLC 系统自推出以来，便在人们的生活与工作中得到了较好的进展，已受到人们广泛的关注。文章从 PLC的角度出发，对地铁售票系统进行相应的科学设计，已此为地铁建设提供重要的帮助，促进地铁产业的进展。关键词：售票系统，优势，PLCAbstract: With the rapid development of the society and economy, the subway train has begun to appear in people's vision. Subway train has the advantage of fast speed and low price, so it has been developed rapidly in major cities. Since the introduction of PLC system, it has been well developed in people's life and work. From the point of view of PLC, this paper makes a scientific design of the subway ticketing system, which has provided important help for the construction of the subway, and promoted the development of the subway industry.Keywords: Ticketing system，advantage，PLC目 录1 前 言........................................................................12.地铁售票机系统方案设计.......................................................22.1 地铁售票机的设计要求......................................................22.2 地铁售票机的方案比较及论证................................................32.2.1 继电器及可编程控制器的方案比较论证....................................32.2.2 单片机及可编程控制器的方案比较论证....................................32.2 系统方案设计..............................................................43.地铁售票机的系统分析.........................................................53.1 地铁售票机的功能分析......................................................53.2 地铁售票机的工艺流程图..................................................53.3 地铁售票机输入控制信息分析..............................................63.4 地铁售票机输出控制信息分析.........
