Atomic clock starting performance evaluation method and device

Abstract

The invention relates to the technical field of atomic clock evaluation, in particular to an atomic clock startup performance evaluation method and device. The system comprises a central controller, a processor, a frequency stability tester, a simulation excitation source generator and a frequency multiplier. According to the invention, a judgment condition is triggered through a central controller, a phase discrimination signal transmitted by an integrator is judged, and when the size of an analog direct current signal is located in a non-enabling band area, the central controller outputs an enabling signal to be 0, and a frequency stability measuring instrument does not work; when the size of the analog direct current signal is out of a non-enabling band area, the central controller outputs an enabling signal 1, and the frequency stability measuring instrument starts to work; at the moment, the simulation Y value is actually a simulation test result value output when the frequency stability measuring instrument works, and reflects the starting frequency performance of the atomic clock, so that the problem of automatic detection of starting of the atomic clock is solved, and the accuracy of the atomic clock in use is ensured.

Description

technical field [0001] The invention relates to the technical field of atomic clock evaluation, in particular to a method and device for evaluating the power-on performance of an atomic clock. Background technique [0002] In scientific research or experiments, the time requirements are very strict, and ordinary clocks cannot meet the precision requirements of scientific research or experiments, and atomic clocks are usually used. [0003] Atomic clocks use the principle of atomic physics. Atoms absorb or release electromagnetic energy according to the energy difference of different electronic arrangement sequences, that is, the energy difference of different electron layers around the nucleus. Here, the electromagnetic energy is discontinuous. When the atom When it transitions from an "energy state" to a low "energy state", it will release electromagnetic waves. The characteristic frequency of this electromagnetic wave is discontinuous, that is, the resonance frequency. Th...

Problems solved by technology

[0004] However, in the process of starting the atomic clock for a long time, the vibration frequency will have a certain deviation, but before the atomic clock is turned on, it cannot detect and evaluate itself, which will lead to a decrease in its accuracy and affect the authenticity of scientific research or experimental data.
