基于小区基表的自动抄表系统的实现

以住宅小区中原有的机械基表为基础，通过加装零功耗磁敏传感器电路，再经过EM78P458单片机的处理，经虚拟UART接口、RS-485总线将测量数据送入上位计算机管理控制中心，从而实现了智能小区的自动抄表系统。该系统具有安装调试方便、性价比高、易于推广等特点，能够在不影响小区原来已有机械基表性能的情况下加装远传抄表系统，加装抄表系统后具备了机械与远传两套显示，且显示具备一致性。

Implementation of Automatic Reading Meter System Based on Community Base Meter

Take the original mechanical base meter originally has which is in the completed community as the foundation, through installs zero power consumptive magnetodependent sensor circuit, again passes through EM78P458 single chip microprocessor processing, after dummy UART interface, the RS-485 bus will survey data to send in the host computer management control center, thus realized automatic reading table system of the intelligent community. This system has convenience, the low low power consumption, be easier than to spread and so on characteristic; remote reading meter system in the situation which not affect the original price, the Can install mechanical base meter performance originally has which is in the completed community, had mechanical and remote transmitting two sets of display systems after installed reading meter, also the display had the uniformity.
