三相电压监控及调压的单片机数据采集系统

Data acquisition system of monolithic computer by three-phase voltage monitoring and requlation

三相交流采样的实现，使微机直接用于电力监控和电压调整，对使用者做到低成本、高性能。采用电阻分压直接采样、高精度Ａ／Ｄ转换、光电隔离等技术，形成单片机系统前向通道的硬件结构，与软件相配合，为计算机提供电网交流电的参数数据。

Three-phase AC sampling makes micro-computer be directly used in power monitoring and voltage requlation, which can be realized in very high performence but with very low cost. Using techniquessuch as direct sampling by resistance voltage-distributing, A/D converting with high accuracy, and photoelectric isolating, etc, we can implement effectively a computer on slice forward-channel, and with thehelp of designed software, we can easily supply the AC parameters in the current network for miro-computers.
