摘　　要：为了响应部分地方分时计价和国家节能减排的政策,设计了这一款基于MSP430的双模式电能测量系统。通过RN8209电能计量芯片测量所用电能,用软件实现将高峰和低谷的用电量分开测量或者在低谷的时候通电,高峰时断电,测得数据通过SPI通信协议送给MSP430单片机,单片机根据时钟信号进行相应的处理。本系统有运行稳定、成本低的特点,同时也有利于节能环保。In order to response stime-sharing valuation and the national policy of energy conservation and emissions reduction, we design this double-mode power measurement system base don MSP430. Electrical energy is measured by RN8209 electricity metering chip. Power measurement is separated power demand high and power demand low by software. It also can control to turn on the power in trough other time turn off by software. The data are sent to MSP430 by SPI. According to the clock signal, the data are processed and the relay is controlled by MCU. This system is stable and cost-effective. It is also good for energy conservation and environmental protection.
