摘要
采用凌阳SPCE061A板控制器,以高精度的三相电能专用测量芯片ATT7022A为核心,实现对三相工频交流电三相电压、三相电流、三相有功功率、三相无功功率、总有功功率、总无功功率、功率因数、电网频率、有功电能和无功电能的测量与显示。电表测量精度高,且具有电压和电流相序检测、掉电存储、密码保护等功能。通过RS-485通信实现远程测量,通过红外通信向掌上PDA手抄表传送信息,并通过按键菜单和LCD显示提供人机交互界面。
This meter adopts SUNPLUS SPCE061A board as the controller,high precision measurement chips ATI＇7022A for three-phase power as the core measure chip, to realize the measurement and display of AC three-phase frequency voltage, current, power phase three, three-phase reactive power, total power, total reactive power and power factor, the grid frequency, and reactive power meritorious electric. The meter has high accuracy, and has the voltage and current detection, and power in sequence, storage, password protection, etc. This design is realized by RS-485 communication, remote measurement to handheld PDA infrared communication of information organizing form, and through the key menu and LCD display provides the man-machine interface.
