Description

SYSTEM OF DISPLAYING NEXT GENERATION ELECTRONIC NAVIGATION CHART WITH RISK NOTIFICATION FUNCTION

The present invention relates to an electronic navigation chart display system, and more particularly, to a next-generation electronic navigation chart display system equipped with a hazard notification function.

Electronic chart display devices currently used in ships only output a warning sound such as a beep sound or a screen warning lamp for a dangerous situation.

Outputs the warning sound and the screen warning light as shown in Table 1 below.

Referring to Table 1 above, the risk of alarms/warnings by using long/short sounds, repeated cycles, etc., or by analyzing the colors displayed on the screen (red (alarm), orange (warning), yellow (caution)) situation is to be distinguished.

With these warning sounds or screen warning lights, it is not possible to know about the specific danger of the vessel, and it is only a warning level. As such, a simple beep sound is continuously sounded until the user recognizes the dangerous situation, so the user's ability to recognize the dangerous situation gradually decreases.

That is, there is a problem in that it is difficult to quickly recognize various risk situations, and the risk is not accurately recognized and insensitive.
