Design of a New Wind Generator

为了解决无线传感器网络节点的供电瓶颈问题,提出了一种通过新型风力发电机将风能转化为电能对无线传感器网络节点提供能源的方法。在该新型风力发电机中风扇作为发电机的一部分,将风扇和发电机一体化,减小了整个发电装置的体积。同时设计了电源管理电路,将新型风力发电机发出的交流电转换为直流电,对锂电池充电和通过电阻对锂电池的输出进行分压并提供给无线传感器网络节点。最终的分析和计算结果显示新型风力发电机和电源管理电路能够实现对无线传感器网络节点提供能源的目标。

A new wind generator is designed for the wireless sensor network node to solve the energy bottle-neck problem of the wireless sensor network node.The new wind generator changes wind energy to electric energy to afford the wireless sensor network node.In the new wind generator the fan works as a part of generator.It integrates the fan with the generator,and as a result,the size of the entire generating set is reduced.Moreover a power management circuit is designed for converting alternating current from the wind generator to direct current to charge up the battery and using resistors to distribute the voltage from the battery.Therefore,it can satisfy the need of the wireless sensor network node.The analysised and computed results show that the new wind generator and the power management circuit is useful to give electricity for supplying the wireless sensor network node with enough energy.
