Abstract: By setting up kinds of time and frequency measurement hardware,we establish a measurement system which can implement many atomic clock compare with local freqency standard at the sametime.This system which is suport with data-base servic in the bottom can survey the measurement data in the real time,show the frequency accuracy of the current measured atomic clock,and after get more appropriate data,it can also calculate and show the result and curve of the day stability and the drift of time.This system can be convenient for the operation of measurement person and improve the efficiency of the measurement on the measured atomic clock.

Key words: Time and frequency, Atomic clock, Measurement system
