摘要
本文介绍了一种电力四遥监控系统中的遥测模块,其控制核心是TI公司的MSP430单片机,采样电路由珠海炬力公司的ATT7022B三相电能芯片构成。这种测量模块,具有三相电能表的功能,可以测量三相电路中电流、电压、频率、功率、功率因数、电能等参数。
The article introduces a measurement module which is one part of Four- Remotion monitoring and control system. It is com- posed of the control unit of single chip of MSP430 made by TI and sampling circuit which is based on the energy chip of ATT7022B of Juli company, Zhuhai. This kind of measurement module, with the function of three- phase energy meter, can be ap- plied to measure electrical parameters such as current,, voltage, frequency, power, power factor, energy.
