Described grading module (5) inclusion grading parameters and the setting of code of points, described grading parameters and code of points
Set, be then to be contrasted according to the dynamic parameter that actual experience data is obtained with this emulation, give in conjunction with related data
Formulate；Described grading parameters include ship maximum break bounds value, most break bounds number of times, away from the urgent value in navigation channel border, away from navigation channel side
Boundary's dangerous values and away from navigation channel border warning value, described code of points divides two kinds, a kind of be one-way track code of points, another
Planting is the code of points of double way channel；
E1, for one-way track it is contemplated that currently the majority navigation channel is all artificial navigation channel, and most of artificial navigation channel is all
It is trapezoidal navigation channel, so for ship navigation safety, not allowing ship to exceed navigation channel border；So after emulation terminates, counting ship
Oceangoing ship exceeds navigation channel number of times, beyond navigation channel border urgent value number of times, beyond navigation channel cutoff risk value number of times with beyond the police of navigation channel border
Announcement value number of times；Consider navigation channel, ship type, ship tonne, Ship's Dimension, the speed of a ship or plane and distinguished and admirable, and with reference to multidigit captain and draw
The many years of experience of boat person and harbour master-plan specification, to set the standards of grading of related parameter values formulation complete set, divide 4
Individual grade, including outstanding, good, pass and fail；
E2, for double way channel, in the case of without prejudice to traffic it is allowed to ship exceed navigation channel inboard boundary, so
After emulation terminates, except statistics is worth number of times, exceeds navigation channel cutoff risk value number of times beyond navigation channel number of times, beyond navigation channel border is urgent
Outside beyond navigation channel border warning value number of times, the maximum break bounds value of ship also to be counted and most break bounds number of times, standards of grading divide 5
Individual grade, including outstanding, good, medium, pass and fail；Automatically according to pre-designed scoring mark after emulation terminates
The grading system of this behaviour's ship of quasi- output；
Described related data includes harbour master-plan specification；
Described historical record and playback module (6) include historical record menu and flight path setting menu, for realizing navigation number
According to record and playback function, described aeronautical data includes flight path, distinguished and admirable and steering data；Described flight path setting menu sets
Put the display mode of ship track, display mode includes that ship type shows or track line shows, the time of Target track displaying is set simultaneously
Interval and the Fill Color of ship type；Emulation points out whether to preserve history flight path, for preserving history flight path and history after terminating
Data；Described historical record menu has loading history record and unloading historical record function, with curve form in main display
History track line is shown on area's sea chart, loads the historical data being saved in text simultaneously；Simultaneously loading history flight path and
Historical data, makes the kinestate of the apparent whole evaluation process ship of understanding of user, also allows for customer analysis evaluation process
Generation faulty operation, find in time and solve problem.
