Design and realization of multifunctional and intelligent protection instrument for electric bicycle

In the present global pollution and the greenhouse effect become more and more serious, it is an urgent problem of the world transportation to develop one kind of new non-pollution, noiselessness the non-oil consumption transportation vehicle. The emergence of electric bicycles make people see that the hope of solving the problem of city traffic pollution, the environmental protection and high efficiency electric bicycles are becoming more and more popular to the people. Combined with modern electronic technology, single-chip technology and intelligent sensor technology, we carry on electric bicycle system hardware circuit design and development of innovation based on Hardware circuit for the electric bike problems. Designed one multifunctional protection instrument based on AT89C2051 which integrated includes sound and light monitor of battery, aided battery charger, speed control circuit and anti-theft devices. The multifunctional protection instrument of electric bicycle is a novel design, good controllability, high stability, and can save results automatically and automatic alarm.
