A method for compressing time series data includes: reading original data including time series data; measuring a unit of the original data; determining a threshold for determining a range allowing for a difference between compressed data and the original data; performing longest distance downsampling to preserve an abnormal point of the original data; storing a start point and an end point of the original data; performing drop-out on the longest distance downsampling result, wherein the drop-out is not performed for the start point and the end point; and if the number of values of the original data is smaller than &#x3b1; times the original data length, storing at least one of the values of the original data as a reference point, wherein &#x3b1; is a real number having a value between 0 and 1.
