摘　　要：传统抄表采用人工方式,不但所需人员多,而且工作量大,效率低下,容易出错.为了改变这种情况,自动抄表系统(AMRS)应运而生,其可以分为有线和无线两种,有线方式有RS485总线方式、M-BUS总线方式,无线方式有GPRS、ZigBee、LoRa等无线技术.基于此,笔者设计了一种基于LoRa技术的自动抄表系统,结合其长距离低功耗特点,解决了现有自动抄表系统成本高的问题.Traditional meter reading adopts manual way,which not only needs more staff,but also has heavy workload,low efficiency and easy to make mistakes.In order to change this situation,automatic meter reading system(AMRS)came into being,which can be divided into wired and wireless.The wired mode includes RS485 bus mode and M-BUS bus mode,and the wireless mode includes GPRS,ZigBee,Lora and other wireless technologies.Based on this,this paper designs an automatic meter reading system based on Lora technology.Combined with its long-distance and low-power consumption characteristics,it solves the problem of high cost of existing automatic meter reading system.
