Embodiment 1
[0036] According to an embodiment of the present invention, an embodiment of a time-series data aggregation method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
[0037] figure 1 A flowchart of a time series data aggregation method provided by an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0038] Step S101, acquiring a time-series data set, and segmenting the time-series data set according to a preset first time window to obtain multiple first time-series data subsets.
[0039] In the embodiment of the present invention, the time-series data set is a collection of time-series data recorded in chronol...
Embodiment 2
[0076] Figure 5 It is a flowchart of another time series data aggregation method provided by an embodiment of the present invention. Such as Figure 5 As shown, in step 1, for the time series data set [T, Y], the data is divided into several segments according to the predefined continuous time window (ie, the above-mentioned first time window). Among them, T represents the time series, and Y represents the sampling data corresponding to the time series (that is, the above indicators), which can be fuel consumption, ship speed, wind speed, etc.
[0077] Step 2, calculate the mean T of T for each subset of time series data m ; Calculate the mean Y of Y m , standard deviation Y std and each sample with Y m difference Δy (i) =|y i -Y m | (i) ,i=1,2,...,n; the statistical difference is higher than the first preset threshold Δy max The number of samples Y N ; then according to Y N and Y std To determine the aggregation method of the subset of time series data: if Y N ...
Embodiment 3
[0089] An embodiment of the present invention provides a time-series data aggregation device. The time-series data aggregation device is mainly used to implement the time-series data aggregation method provided in the above content of Embodiment 1. The time-series data aggregation device provided in the embodiment of the present invention will be specifically introduced below.
[0090] Figure 6 It is a schematic structural diagram of a time series data aggregation device provided by an embodiment of the present invention. Such as Figure 6 As shown, the time series data aggregation device mainly includes: an acquisition segmentation unit 11, a first segmentation unit 12, a second segmentation unit 13, and a first aggregation unit 14, wherein:
[0091] The segmenting unit 11 is configured to obtain a time-series data set, and segment the time-series data set according to a preset first time window to obtain a plurality of first time-series data subsets: wherein, the time-series...
