摘要
针对机械、电子式电能表精度低、损耗大、不稳定等缺点,设计了基于ARM9的高精度智能电表系统。设计采用了S3C2440A微处理器为核心的ARM9开发板系统和ADE7755电能测量芯片,能对采集到的电能信号进行计量、实时监控、信息存储和处理、网络通信等操作。理论分析和测试结果表明,系统符合设计要求,具有良好的应用前景。
Aiming at the disadvantages of low accuracy, great loss and unstableness by electronic energy meter, the high accuracy smart meter system based on ARM9 was designed. The proposed design method utilizes the ARM9 development board system based on $3C2440A microprocessor and electric energy meter chip of ADE7755 to calculate, monitor, storage, process and communicate in network for electric energy signal. The theoretical analysis and the results indicate that the system accords with the design requirement and has a good application prospect.
