AI Technical Summary
Technical Problem
[0008]本实用新型提供一种双冗余集中供电的水表，通过电池包、应急电源和检测单元相配合，使用通信可靠性高、功耗低，不缺乏应急供电机制，电池更换容易且成本低，通过设置的18650锂电池作为备用电源，实现“双电源冗余”，在外部断电时自动切换，使其持续运行与数据不丢失，解决了上述背景技术中所提到的电池更换困难且成本高，通信可靠性低、功耗高，缺乏应急供电机制的问题
Benefits of technology
[0021]1、该双冗余集中供电的水表中，通过本地通信模块与计量采样模块电性配合，可快速将采集到的水流信号转化为数据信息，再通过本地通信模块与本地集中器进行短距离无线通信，在获取蓝牙数据后，再通过NB-IoT或4G网络上传至远程服务器，进而降低通信功耗与提升成功率，采用蓝牙替代NB-IoT进行本地通信，功耗更低，且在短距离、封闭环境(如管道井)中通信更稳定，数据传输成功率高；
