远程抄表系统中后备电源的设计

Design of UPS in automatic meter reading system

本文主要讨论了四表远程抄表系统中采集器后备电源的设计,此后备电源能维持采集器在市电停电时继续工作且连续工作时间不少于48 h,后备电源在市电上电时能适时充电,以备下次启用,且能对后备电池工作异常现象进行自动检测,能够发出告警灯信号等功能,充分保证系统能够正常完成计量工作。

The paper mainly introduces the design of an UPS in automatic meter reading system, This UPS can keep the data acquisition device working and the continuous working time is not less than 48 hours when the power is off. It can charge up itself timely as the power is resumed and is ready to be used next time. The UPS can also detect automatically the batter abnormity condition and send out warning light signal. In a word, the UPS can fully ensure the meter reading system operating properly.
