工作阻力可调的自行车发电器接口电路的设计

Design of interface circuit for bicycle generator with adjustable working resistance

自行车发电技术顺应了可持续发展的趋势,并且该技术也逐渐成熟。但是目前的发电设备由于发电机受车轮转速的影响较大,导致骑行费力而无法推广。讨论并设计了一种工作阻力可调的电路装置,通过MSP430低功耗单片机采集外部能量信息来控制发电设备进行开闭调节。根据骑行者不同的体力状态来调整发电装置所产生的负荷,以减轻使用者的负担。经过理论验证和大量测试,结果表明本装置可以实现自由调节自行车发电设备的负荷。

Bicycle generating technology conforms to the trend of sustainable development,and becomes gradually mature. However,it is difficult to promote this technology,because the generators are greatly affected by the wheel speed,which brings more resistance to riding. A load-regulating circuit device is discussed and designed in this paper. The MSP430 microcontroller is in the charge of collecting the external energy information and controlling regulation of the power generation equipment. By means of the load adjustment,the generator will accommodate to the different physical conditions of user and reduce the burden. This generator equipment has been verified through theory and multiple experiments. The experimental results show that the bicycle generating equipment can adjust the load of itself under different circumstance.
