Uses the 89C52 monolithic integrated circuit for the primary control chip, using the pressed key signal imitation rental car wheel counting signal, simultaneously utilizes other pressed keys to control the rental car movement to carry passengers separately/the spatial vehicle condition, the kilometer idea regulation/waiting time and the traveling schedule expense amount to the demonstration. The system used three groups of nixietubes, the utilization dynamic display technology has demonstrated the distance in kilometer, the standby period and the expense separately. Meanwhile carries on the design using the software programming to the monolithic integrated circuit timer, produces the waiting timed pulse signal. this article elaborated with emphasis systems principle of work, the hardware constitution, various part of major functions as well as softwares structure and realizes. The mileage log system with STC89C52 as control core, using sensors to detect signals, by a certain time interval signal collection, in combination with itself, bicycle wheel parameters through single chip microcomputer fo
