如何结合ZigBee和EnOcean Alliance驱动能量收集了IIoT
标准是物联网发展的基本要素,特别是工业设备。这是特别明显的,在网络的心脏和它们的使用与电池电源的无线连接。虽然有一些全球标准在2.4 GHz频段,如ZigBee和潜在的蓝牙,这些仍然有挑战的无线节点的功耗,主要是由于使用的协议,更侧重于数据连接的结果。虽然这些已经获得了牵引系统的有线电源,有一个移动收获能源,特别是在工业应用中,这些协议可以太耗电。
在工业网络中,成千上万的电池供电的无线节点,更换电池是一个主要的操作成本和网络操作的风险。电池的变化必须被安排,以确保节点不失败和重要的数据是不会错过。由于这些网络连接到互联网和数据被送入云进行分析和监测,这种可靠性更重要。
As a result, organizations such as EnOcean developed their own wireless protocols, often based on small telegrams of data, that use tiny amounts of power that can be scavenged from indoor lighting, thermal differences or the vibration of the equipment itself. Even if the energy available is not quite regular enough for constant power, using energy harvesting to recharge batteries can dramatically extend the battery life of the wireless nodes to many years, boosting the acceptance of the technology and enabling the roll out of the industrial Internet of Things (IIoT)。
EnOcean’s EDK350 development kit shown in Figure 1 includes a programmer/demo board with the USB 300 USB gateway to connect to a PC to control the TCM 320 transceiver module and STM 300 sensor module. It also includes a solar powered temperature sensor, push button transmitter, mechanical energy generator, and transmitter module to demonstrate all the elements of a self-powered network.
