The bicycle speedometer can fulfill the basic need of people’s life, so that they can learn the speed, the mileage, Time, temperature of the bicycle. In this paper, the bicycle speedometer design based on the Hall element is elaborated. By AT89S52 as kernel, using Hall element to measure revolution, the measure and statistic are achieved. The range information is saved by 24FC512 when the power is off, the bicycle speed can be displayed on LCD. In this article, the hardware circuit and software design of bicycle speedometer instrument are introduced in detail. About the hardware, the pulse number is transmitted of one cycle of the bicycle into Single Chip Microputer system. Then the signal processed by Single Chip Microputer system is sent to display scream. About the software, in assemble language。 the program is designed in the mode of modules. The system has simple hardware, mon subprogram, and meets the demand of design. For the sake of easy to expand with the design adoption mold a logic for turning construction, making procedure designing relation that change, software more shorter and more easier to understand. Make hardware control in software descended to moderate the operation. The text inside describes the system hardware work principle in brief first, and attach with the system hardware design frame diagram, bine development history that introduced the single a machine microprocessor, discuss this graduate design a function for applied each hardware connecting a people the technique connects with each one a mold piece and work processes, bine to describe in a specific way the AT89S52 electric circuit connects oscular and soft, the hardware adjusts to try. Expatiated the process of the procedure the next in order with realizes process. The simulation results have proved that the hardware circuits design and software program is correct, and the system can meet the designing requirement pletely.
