摘要
采用MSP430F149单片机作为控制核心,利用蓝牙技术实现充电系统与可携带式电子产品之间的信息匹配,通过电磁谐振技术传输电能,将接收到的电能经过整流稳压电路实现恒压输出,最后通过充电管理模块实现为锂电池充电。该设计利用蓝牙技术,实现一对多或是多对多匹配连接,具有充电状态提示、充电可控和电池充满电后自动断电的功能,摆脱以往电线的束缚,解决了电子产品充电接口不兼容的问题,适用于各手持移动设备以及小型用电器。
The microcontroller MSP430F149 is taken as control center in this system. The Bluetooth technology is used to realize the information matching between the chargers and portable electronics. The electric energy is transmitted by electromag-netic resonance technology,and of constant voltage output of electric energy is achieved through commutating and voltage-stabi-lizing circuit. The lithium battery charging is fulfilled by the charging management module. The advantages of Bluetooth technolo-gy is utilized in this design,which can realize one to many or many to many matching connection,has functions of charging state hint,charging control and auto power-off after battery is fully charged. It got rid from the previous wire,and solved the charger interface incompatibility of electronic products. It is suitable for various mobile devices and small appliances.
