【摘要】 基于嵌入式系统和GPRS技术的电力远程抄表监控系统,由智能检测终端、GPRS数据传输、因特网传输、信息管理中心服务器4部分组成。通信使用2个异步串行口。片内实时时钟用于定时数据采集、处理和传输。片上看门狗防止系统死机及系统复位。外扩2MBNORFlash和8MBNANDFlash存储系统程序和抄表数据。16MBSDRAM为系统内存。操作系统采用uC/OS。应用软件由M-bus抄表、接入GPRS发送数据和电网监控部分组成。更多还原

【Abstract】 The electric remote meter reading and monitoring system based on the Embedded System and GPRS communication technology consists of intelligent examine terminal, GPRS data transmission, internet transmission and information management center server. Two UARTs were used for communication. The RTC was used for timing data collection, processing and transmission. Watchdog prevented system crash and reset. The 2MB NORFlash and 8MB NANDFlash stored the system program and reading data. The 16MB SDRAM was the system memory. The operating system was uC/OS. Application software consists of M-bus meter reading, and GPRS data transmission and monitoring component.更多还原
