自动抄表器(AMR)改装模块

概览

描述

随着越来越多的用户要求水表、暖气表和燃气表具备自动抄表(AMR)功能,许多公用事业单位都选择在现有的机械仪表上使用经 MID 认证的“即插即用”改装模块。 相较于在机械仪表寿命到期前就将其全部替换成电子仪表,这是一种非常可行的方案。

虽然下列方案专为机械水表改装模块而开发,但其工作原理与介质无关(适用于暖气表和燃气表),完全兼容电子直驱仪表(无机械齿轮箱)。

系统优势:

  • 灵活的低功耗 MCU 选件减少了 BOM 数量,可以使各种类型的仪表实现单芯片功能:
    • 机械/改装仪表:在配备低成本的 MCU 的简易版改装设计中可同时运行计量(测量能源、水或燃气)和应用(通信协议、数据处理)功能。
    • 带有电子显示屏的仪表:减少外部组件数量,采用带有片上 LCD 控制器的 MCU,为用户提供一个仪表界面,提升其使用体验。
  • 设计灵活,支持使用瑞萨电子其他款 MCU,以适应未来市场趋势,对于复杂的通信方案尤其如此。
  • 降压升压 DC/DC 转换器通过高效利用电池的可用容量,增强了射频收发器的可操作性,并显著地延长了系统寿命。
