Classic of AC (Alternating Current) sampling for power network signals was introduced working principles and error resources in realizing period rounding error and their compensation methods were proposed. Thoughts to keep synchronous when power network was distorting were discussed. According to sampling requirements for power network parameters of double power resources automatic transforming switch, combining ARM technology, a software synchronous sampling system realization scheme based on LPC2318 and MAX123 was proposed. Using this method to measure double power sources automatic switch power network signal’s effective value power higher harmonic and recording faults hardware complexity can be lowered and accuracy ensured. It can synchronously avoid measurement error of voltage and current phase difference, greatly reduce period error, shorten sampling time and enhance measuring accuracy. Designing changing frequency synchronous sampling overcomes sensitivity of common AC sampling to period, and enhances sampling accuracy and reality as well.
