| description | The invention discloses a drag suction dredger parameter analysis and process identification method based on ship AIS data. The method comprises the steps that 1, drag suction dredger navigation trajectory data are extracted; 2, preprocessing the navigation trajectory data; step 3, performing construction area identification based on the construction behavior characteristics of the trailing suction dredger; 4, construction starting and ending time is recognized; step 5, identifying regional information of the construction process flow; step 6, project type discrimination; step 7, dividing no-load and full-load data sets; 8, segmenting and storing each track data set into a primary action track fragment cluster; step 9, calculating to obtain each construction process parameter according to each action track fragment cluster set; and step 10, pre-estimating the construction soil texture and the construction process. According to the method, the four action links of digging, throwing, blowing and transporting in |
