毕业设计说明书目． 基于单片机测速仪设计000 名．指导老师： 专业年级： 级机械设计制造及其自动化专业（机械电子工程方向〕所在学院和系． 机械工程学院完成日期： 6月 8 日答辩日期： 6 月 13 日基于单片机测速仪设计摘要本设计主要阐述一个基于单片机与霍尔传感器等元骨测速仪设计。以 STG 单片机为关键，实现对自行车里程、速度、时间、温度等参数测量，并能简单将里程及速度用 LCD 实时显示：说明书中详细介绍了测速仪硬件电路和软件设计。硬件部分利用霍尔传感器将每秒内脉冲数传入单片机系统，然后经单片机系统计算处理并将过处型结果送 LCD 显示。软件设计实行模块化结构，使程序逻辑关系愈加简练。佼硬件在软件控制下协调运作。仿真和试验表明，所设计硬件电路及软件程序是正确，实际硬件电路中也基本上能够满足设计要求。关键词．里程/速度，时间，温度，霍尔元件，单片机，LCDTHE CIRCUIT DESIGN OF VELOCIMEETER BASED ON MCUAbstractThis design mamly elaborated based on MCU and Hall element of speed mstmment design. Take STC MCU as the core, Hall element speed, realizes to the bicycle mileage, speed, time, temperature measurement, and a simple bicycle mileage and speed with the LCD real time display The hardware pan using the Hall element will bike per second pulse number of incoming MCU system, and then by the single chip microcomputer system calculation processing and processing result to the LCD display Program desxgn in ordec to facilitate the expansion and the change, the softwar design uses the modular snucture, make the logic relations more concise. Make hudware tocoordinatethe opecation under the software contiol. Simulation experunents show that the designed haldware cilcuit and software program are correct, pmctical Imdware circuit also basically can satisfy the design requirement, but due to the knowledge and the level IS limited, m practice there are still some problems in the Imdware circumKeywords: Mileage / speed,time, tempe...
