摘要
以空间电磁场分布为研究对象,根据电磁感应法理论和计算机技术研制了工频电磁场测量仪。详细介绍了基于单片机P89C51RC+,高精度低噪声仪用差动放大器AD624,以及具有三态缓冲电路,可与8/16位微处理器总线挂接,12位逐次逼近式模数转换芯片AD574的工频电磁场测量系统软硬件设计。
For the sake of the research space the electromagnetism ranged, based electromagnetic induction method and calculator technique, power- freguency electromagnetic fields measurer; P89cS1RC＋ AD624; AD574 This article detail about connection of highly precious and low noise AD624 and circus link the bus of 8/16 bit microcontroller, in an addition, the design on hardware and software of measurement of power - frequency electromagnetic fields of 12 bits successive approximation A/D574converter.
