摘要
采用STC12C5A60S2单片机配检测电路,用作为异步电机功率因数的数字测量。介绍了数字测量原理和相关的数学公式,并给出测量电路图和单片机系统电路图以及相关的程序,对实际应用有很好的参考价值。
STCI2C5A60S2 single-chip combined with detecting circuit was applied as the digital measurement to measure the asynchronous motors＇ power factor. The prin- ciple and mathematic formula of the digital measurement were introduced while the detecting circuit diagram, single- chip systematic diagram and relative procedure were put forward. These principle and diagram had very good refer- ence value in the measurement activity.
