摘　　要：为生产可靠、稳定且灵活性好、开发周期短、效率高、维护简单的出租车计费器,提出了在QuartusⅡ 9.0软件平台上,基于FPGA的出租车计费器的设计方案。通过VHDL描述出租车计费系统的操作流程及控制方案,实现模拟汽车的启动、停止、计费、暂停、预置等功能,并用LCD1602显示车费、里程、等待时间、行驶单价等信息。该系统配合车速传感器可应用在不同车型的出租车上,并达到预期功能。For the production of taxi meters that are not only reliable, stable and flexible, but also has the short development cycle, high efficiency and is easy maintenance. Based on FPGA （ Field Programmable Gate Array）, a scheme of taxi fare meter is designed on the QuartusII 9.0 platform. The operational processes and control scheme of the taxi billing system are introduced in this paper by using VHDL （Very-High-Speed Integrated Circuit Hardware Description Language）, to implement the simulation of the car＇s functions such as start, stop, billing, pause, preset and so on. And it displays the tariff amount on the LCD 1602. With the speed sensor, the system can be used in different models of taxi, and achieve the expected functions.
