如何在工业物联网中使用能量收集
 
  一个能量收集源开发一个系统可以是一个挑战,低和不规则的电压给设计师一种用于物联网产业的无线传感器网络提供一致的功率头痛(IIoT)。
 
  低成本和高可靠性比数据速率更重要的是在工业物联网,和半导体厂商已经把自己的评价系统,以帮助设计师制定出最佳的方式来使用他们周围的能源,从各种来源的节点供电。
 
  使用能量收集扩展充电电池的使用,从一年到十,大大降低了工业物联网的运营成本,从成千上万的传感器更换电池。这不仅仅补偿无线节点的额外复杂性。在某些情况下,设计师甚至可以完全消除电池,以节省进一步的成本和复杂性,在网络操作。
 
  
 
  Some of the sources are more established than others. Photovoltaic solar cells are able to provide a regular supply of current at predictable voltages, even from the indoor fluorescent lighting that is found on the factory floor. This can be used with a power manager that is optimized for energy harvesting such as the ultra-low-power SPV1050 from STMicroelectronics that implements a maximum power point tracking algorithm (MPPT) with an input voltage range from 75 mA.
 
  Alongside the MPPT function, the SPV1050 integrates the switching elements of a buck-boost converter, which allows it to charge off any battery, including the thin film batteries, by tightly monitoring the end-of-charge and the minimum battery voltage in order to avoid the overdischarge and to preserve the battery life.
