摘要
文中基于GPRS的优势设计了一种经济实用的电力自动抄表系统.该系统底层通信基于RS-485总线传输,上层通信基于GPRS,其中GPRS模块采用中兴的ME3000.系统硬件结构简洁,包括微控制器与GPRS模块的外围和接口电路、实时时钟、存储单元.软件设计采用C语言进行软件编程,有利于软件的模块化,便于维护和移植.经调试,系统功耗低,运行稳定可靠.
A kind of economical and practical electricity automatic meter reading system is designed, on the advantages of GPRS. Bottom communication of the system is based on RS-485 bus transfer, and upper layer communication is based on GPRS by using ZET ME3000 Module. The hardware of system is compact, including peripheral circuits and interface circuits between microcontroller and GPRS Module, real-time clock and memory cell. C language program, which is used to design the software, benefits the modularization of software and is easy to maintain and transplant After adjustment , the system is stable, and power dissipation is low.
