Time series data processing method, system and equipment and medium

The invention provides a time sequence data processing method, system, device and medium, the processing method comprises the following steps: obtaining a time sequence compression package and obtaining a to-be-queried target time, the time sequence compression package comprises a head frame and a plurality of bitmap frames, the head frame is used for recording a starting timestamp and a time sequence interval of a time sequence data set, and the bitmap frames are used for recording a plurality of bitmap frames; and frame information of the bitmap frame; according to the starting timestamp and the time sequence interval, performing difference value processing on the target time to obtain a target difference value; and performing query processing on all the bitmap frames according to the frame information and the target difference value to obtain a query result of the target time. According to the processing method, the storage resources occupied by the time sequence data are effectively reduced, the query eff
