The invention discloses a traffic time series data anomaly detection method fusing multiple mechanisms, and relates to the technical field of data anomaly detection. Acquiring traffic time sequence data of a previous time period of the to-be-predicted time period; taking the traffic time sequence data of the previous time period as the input of a traffic time sequence data prediction model for operation, and obtaining the traffic time sequence prediction data of the to-be-predicted time period; determining a Gaussian distribution probability density value of a traffic data error value corresponding to each time point of the to-be-predicted time period based on the traffic data error value corresponding to the same time point in the traffic time sequence data of the to-be-predicted time period and the traffic time sequence prediction data of the to-be-predicted time period; and determining whether the traffic data corresponding to each time point in the traffic time sequence data of the to-be-predicted time period is abnormal or not based on the Gaussian distribution probability density value. According to the traffic time series data anomaly detection method fusing multiple mechanisms disclosed by the invention, anomaly detection can be accurately carried out on long-sequence traffic time series data.
