Definitions

  • a ship movement prediction technique for example, the following JP-A-2009-286230
  • JP-A-2009-286230 that provides an estimated arrival time of a ship destination in real time using AIS data, or a ship service data and predicted weather data
  • AIS data AIS data
  • ship service data and predicted weather data are used.
  • JP 2009-025860 A there is a technique for calculating an optimum route
  • the central processing unit 305 is, for example, a general-purpose processor.
  • the central processing unit 305 functions as an operation data extraction processing unit 308 and an operation data display processing unit 309 by reading the program of this embodiment. That is, the operation data extraction processing unit 308 and the operation data display processing unit 309, specifically, realize their functions by the central processing unit 305 executing a program stored in the program memory 306, for example.
  • the ship number 400 holds a value uniquely assigned to the AIS data 316.
  • the IMO number 401 holds, as a value, an identification number of a ship assigned to a large ship by the International Maritime Organization.
  • the ship name 402 holds the name of the ship registered in the IMO as a value.
  • the ship type 403 holds the ship type name registered in the IMO.
  • the maximum speed 404 holds the maximum speed that can be operated by the ship's engine.
  • the time when the last operation time series data 808 is received in the operation data 318 is held as a value.
  • a time difference between the reception time 803 of the start point and the reception time 804 of the end point in the operation data 318 is held as a value.
  • the route number 806 holds route identification information in the operation data 318.
  • the operation type 807 holds information for determining the operation type of the operation data 318 as a value.
  • the operation time series data 808 holds information such as the position and speed of the ship for each time.
  • the values t1 ′, t2 ′,... Of the operation time series data 808 (hereinafter collectively referred to as operation time series data t ′) correspond to the time series data t in which “0” is held in the deletion flag 506. .
  • the classification device 3 writes the operation data 318 on the data memory 307 in the operation data DB 602 (step S1006). Then, the classification device 3 determines whether all the AIS data 316 on the data memory 307 have been processed (step S1007). If there is unprocessed AIS data 316 (step S1007: No), the process returns to step S1002, and the AIS data 316 for one unacquired ship is acquired from the data memory 307 (step S1002). On the other hand, when all the AIS data 316 are processed (step S1007: Yes), data is displayed using the operation data display processing unit 309 (step S1008). An example of display contents and display processing of the operation data display processing unit 309 (step S1008) will be described later in detail with reference to FIGS.
  • time series data t during berthing is, for example, time series data t where the speed 504 is equal to or less than the speed threshold during berthing.
  • the time series data t of the speed exceeding the upper limit of use is, for example, time series data t in which the speed 504 is larger than the maximum speed 404 of the ship.
  • the time series data t of deceleration for berthing or acceleration for voyage is, for example, the amount of change in speed within the deceleration time required for berthing from voyage or voyage from berth. Time series data t exceeding the speed change upper threshold.
  • the classification device 3 acquires the i-th time-series data a from the AIS data 316 (step S1201), and adds the time-series data a to the operation time-series data 808 in the operation data x (step S1202).
  • the index i is a positive integer starting from 1.
  • the index i is incremented when the next step S1100 is performed.
  • the classification device 3 acquires one unprocessed operation data x from the operation data 318 in a ship of one shipping company (step S1800).
  • the classification device 3 normalizes the operation time series data 808 in the operation data x for each cell, with a certain spatial range overlapping with the operation data x as one cell (step S1801).
  • An example of normalizing AIS data for each cell will be described later in detail with reference to FIG.
