武汉地铁自动售票机软件结构研究与设计

Research on software structure of ticket vending machine in urban rail transit

为了进一步了解自动售票机的内部结构及功能模块,采用了面向对象的程序设计方法,通过对自动售票机的用户以及功能分析,对自动售票机软件的分层体系结构进行了划分,并对每一层的结构进行详细阐述,得出了自动售票机软件的分层体系结构。

The inner construction and function of ticket vending machine（TVM） are discussed.By analyzing the user and function of TVM,a multi-layer architecture based on object-oriented programming is designed,and an evaluation of components is proposed.Thus,the multi-layer architecture of TVM can be gained.
