基于MSP430+ATT7022B的三相三线多回路多功能电能表的研究
Research on Multi-Loop Multi-Function Watt-Hour Meter in Three-Phase Three-Wire System Based on MSP430 and ATT7022B
摘要
Abstract
The paper designs a 24 loop three-phase three-wire multi-function watt-hour meter based on MSP430 and ATT7022B. With the idea of time-sharing multiplexing, the MSP430 controls three ATT7022B to realize measurement and testing of 24 loops. The device can not only meet the requirement of accuracy for detection and measurement, but also has advantages of simple structure and low cost. The paper also shows the overall structure of the watt-hour meter, principle diagrams of multi-loop voltage and current collection modules and software flowchart. Finally, the paper prospects its expanding applications in future.关键词
