简介

从执行器单元按照主执行器的指令,控制一个家庭房间或一片楼宇区域的风扇或 HVAC。它能够提供以下一种或全部风扇控制:

  • 直流无刷 (BLDC) 风扇电机的 RPM
  • 流动方向,即进/出(以及可选地向上/向下,向左/向右滑动)
  • 流量传感器(升/分钟)
  • 电加热器 0% - 100%

如果执行器控制的是 HVAC 而不是简单的风扇,则它可能需要自身附加的传感器和输出,才能更好地控制 HVAC,例如:

  • BLDC 压缩机电机的 RPM
  • 压缩机压力传感器(条形)

使用电容触摸或简单按钮和/或 LCD 的附加 GUI 可用于显示本地值和输入数据。也可以通过主执行器、IP 网关或智能手机来实现更复杂的 GUI。可以轻松添加实时时钟 (RTC),根据日期、时间、节假日等在不同的操作模式之间进行切换。所有 RTC 也可以在系统内实现同步。

系统优势:

  • Bluetooth® 5 网状通信可实现与其他传感器和执行器的通信。Bluetooth 5 的优点包括:
    • 安全的双向分组数据流
    • 低功耗(连接时平均下降到 µA)
    • 不需要额外的接线
    • 自动路径选择(不需要为路由本身设置)
    • 可扩展的速度与范围(即,根据位置不同,可选四倍范围或双倍速度)
  • 对于电源,通常需要使用楼宇控制系统的电源(例如 230Vac、110Vac 或 24Vdc)。瑞萨电子根据实际使用情况,提供了一套完整的解决方案。
