摘要
为克服现有抄表方法的缺陷,以GSM通信模块为核心开发了远程无线抄表终端系统,介绍了其软硬件构成和设计方法.抄表终端通过RS485总线读取电能表数据,并遵循我国电力行业通讯规约标准,然后通过GSM网络与抄表中心进行数据、命令传输,最后实现无线远程抄表.该方案成本低、实时性好.
The remote and wireless electrical-meter-reading terminal based on GSM module is introduced, the structure and design methods of the terminal' s hardware and software are detailedly discribed too, the terminal reads the electrical meter by RS485 bus in accordance with DL/T645 communication protocol, then transmits the commands and data to the meter-reading centre through GSM network. The design is low-cost and real-time.
