阶梯式公交计价系统的设计与实现

Design and Implementation of the Ladder Bus Pricing System

针对目前各城市公交收费现状,提出了一种基于GPS的公交分段计价系统的实施方案。据此方案,给出了分段收费Pos机的基本硬件架构,详细阐述了Pos机分段计价的嵌入式软件实现流程,并对设计好的Pos机进行了现场的跟车测试。测试结果表明,该系统可以实现站台的自动检测,自动扣费;乘客可以从任意门上下车,灵活性强;此外,该系统不仅可以兼容现有的一票制,使得任何一辆车都可以作为机动车随时地代班故障车;同时还能够有效地处理各种逃票现象。

A GPS-based bus segment pricing system is proposed and implemented. The basic steps are to give the hardware architecture of the pos machine, to describe the embedded software flowcharts and to make the on-site test on the bus. The test results show that the system can achieve the automatic detection of the site, automatic deductions and is compatible with the existing one-vote system, and other car may be used to replace a fault car.
