摘要

本文提出了一种针对分布式发电风速测量的能量自主智能传感器。该传感器结合了微型涡轮和小功率直流发电机,将风速转换为待测电压。在测量风速的同时,智能传感器从风中收集能量,为2.4 GHz收发器供电,能够将风速信息发送到几米外的计算机。该解决方案能够在风速低至3.5米/秒的情况下正常工作,这是中小型商用涡轮机的典型下限。这种低成本的智能传感器可以配置在无线网络中,这样就可以在建筑物、交通灯、树木等地方部署多个节点。我们介绍了用于表征传感器的设置,以及收集的实验数据,例如风速与输出电压或不同负载条件下的输出功率之间的关系。

Energy-autonomous wind speed smart sensor
This article presents an energy-autonomous smart sensor targeting wind speed measurements for distributed energy generation. The sensor uses a combination of a micro-turbine coupled to a small-power DC generator, to convert wind speed into a voltage to be measured. Concurrently to measuring wind speed, the smart sensor harvests energy from the wind to power a 2.4 GHz transceiver, being able to send the wind speed information to a computer several meters away. The solution is able to properly work from wind speeds as low as 3.5 m/s, a typical lower limit for small and medium size commercial turbines. The low-cost smart sensor can be configured in a wireless network, so that several nodes can be deployed over buildings, traffic lights, trees, etc. We present the setup used to characterize the sensor, along with the experimental data collected, such as the relation between wind speed and output voltage or output power for different load conditions.
