基于单片机的电子里程器设计

哈尔滨工业大学华德应用技术学院毕业设计（论文）AbstractWith the rapid development of the economy,people's existing material needs areconstantly improving,and the quality of living standards is constantly increasing.Traditional bicycles can no longer satisfy people.People not only use it to travel,butalso innovative bicycle assistive tools are increasing and functioning gradually.It hasbecome one of the ways people travel in low-carbon life and become people.Thefirst choice for leisure,exercise and entertainment.The emergence of electronicspeedometers not only makes people know their riding time,riding speed and thenumber of axioms of riding,but also enriches people's basic needs.This paper mainly uses STC89C52 single-chip microcomputer as the core,andcompletes the design of electronic speed odometer through single-chipmicrocomputer.The hardware adopts STC89C52 minimum system module,Hallpulse module,setting and starting module,display module and calendar moduleblock.The software part is in C language..The design of the paper uses the Hallsensor to measure the number of revolutions,and the 24C02 realizes the preservationof the data.At the same time,it is displayed by the LED display screen,and the datedata is obtained by using the temperature chip 18B20.Keywords:single chip microcomputer;Hall sensor;Speed /mileage;Led display-
