"基于单片机设计的自行车测速计系统-毕业设计：2013届，学号，完成时间"。

本毕业设计的目的是基于单片机设计一种自行车测速计系统，通过检测自行车的车速并实时显示在液晶屏上，以提高自行车运动的体验。设计的系统包括传感器模块、单片机模块、显示模块和电源模块。传感器模块用于检测自行车轮胎转动的脉冲信号，单片机模块通过接收并处理传感器模块的信号来计算车速，并将结果显示在液晶屏上。在实际测试中，系统具有良好的测速准确性和稳定性。通过本设计，不仅可以满足自行车爱好者对车速测量的需求，还可以为后续自行车智能化系统的设计提供基础。 Abstract: This graduation design aims to design a bicycle speedometer system based on a single chip microcomputer, which detects the speed of the bicycle and displays it in real time on an LCD screen to enhance the experience of cycling. The system includes sensor module, single-chip microcomputer module, display module and power module. The sensor module is used to detect the pulse signal generated by the rotation of the bicycle tire. The single-chip microcomputer module calculates the speed by receiving and processing the signal from the sensor module, and displays the result on the LCD screen. In practical tests, the system demonstrates good accuracy and stability in speed measurement. Through this design, not only can the system meet the needs of bicycle enthusiasts for speed measurement, but it can also provide a foundation for the design of subsequent intelligent bicycle systems.
