超级电容器平滑传感器节点的功率需求
Internet of Things(ITT)的传感器节点需要两个或两个sustain能够代表大学的短脉冲串的活动。然而,在需求的突然变化可以从电池deplete细胞比预期的快,性问题和远程安装,可能需要使用一larger扩张,更多的细胞比冰的必要。《超级电容器提供一个方法在两个电荷DELIVER需要支持突发性大学预备期,不应力的子电池。这条examines作用在物联网的超级电容器的设计和explains及其化学技术允许他们爆发活动提供支持。
物联网承诺,大大提高了系统的智能处理环境,运输和工业控制,通过使用高度分布式的半自治传感器和执行器节点放置在他们需要的地方。在物联网传感器节点设计的关键要素之一是它的能源自主性:使用能量采集,长寿命电池或两者的组合,以确保五,十年甚至二十年的寿命。这类设计,每毫焦耳数,需要小心注意细节。
在一个传感器节点的寿命,平均功耗将非常低,这使得它有可能在某些情况下,提供从收割机,如光伏(PV)模块所需的所有能量。然而,平均功耗隐藏的传感器节点的占空比的影响。
Typically, the IoT node will spend much of its TIme in a low-power sleep mode, waking only periodically to take a sensor reading. Very often, microcontrollers employ hardware assistance to reduce the number of TImes that the processor core itself needs to be started to execute software. A dedicated state machine for the sensor interface can be set up to take the reading and then only send an interrupt to the MCU if it is outside a programmed limit. If that occurs, the MCU can wake and perform further processing and if, in turn, it is an important change that needs to be reported, a wireless message can be sent out to a remote server via a low-power radio-frequency connecTIon.
