Atomic clock anomaly detection method, system and device and computer storage medium

The invention discloses an atomic clock anomaly detection method, system and device and a computer storage medium, historical state information of a to-be-detected target atomic clock is acquired, and the historical state information comprises state information of the atomic clock at a preset number of historical moments; estimating the estimated state information of the target atomic clock at the target moment based on the historical state information, wherein the time difference between the target moment and the last historical moment is a preset time difference; acquiring real state information of the target atomic clock at the target moment; and detecting whether the target atomic clock is abnormal or not based on the real state information at the target moment and the estimated state information at the target moment, and obtaining a corresponding abnormality detection result. According to the method and the device, whether the target atomic clock is abnormal or not is detected based on the real state inf
