Atomic time calculation method

The invention discloses an atomic time calculation method, and relates to the technical field of time frequency. When atoms are jointly generated based on multiple atomic clocks, a decentration methodis adopted, each atomic clock participating in calculation serves as a node, each node can express the calculation result of the atomic time, and when a measurement reference clock is abnormal, a measurement reference atomic clock does not need to be replaced, so that the application range is expanded, and manpower and time are saved; the atomic time is a result jointly expressed by all nodes, namely the deviation between the clock face readings of all the atomic clocks and the atomic time, so that the calculation accuracy of the atomic time is improved; and measurement data of each atomic clock is directly used for correcting the atomic clock, and the calculation process is simplified. 本发明公开的原子时计算方法，涉及涉及时间频率技术领域，基于多台原子钟共同生成原子时，采用去中心化的方法，使每一台参与计算的原子钟均作为一个节点，每个节点均可以去表达原子时计算结果，当测量参考钟出现异常时，不需要更换测量参考原子钟，扩大了适用范围，节省了人力
