Description

AIS device for route marking and a light buoy having the same {AIDS TO NAVIGATION AIS DEVICE AND LIGHTED BUOY WITH THE SAME}

Embodiments of the present invention relate to AIS technology.

AIS (Automatic Identification System) is a system built and operated in accordance with the SOLAS: Safety Of Life At Sea (SOLAS) to prevent ship collision accidents and secure safety and security at sea. AIS prevents ship accidents and prevents ship accidents by sharing the status information of ship voyage information and course signs through ship-to-vessel, ship-to-coast, route mark and ship, and route mark and sea data communication between the coast. ), and is used for the function of efficiently controlling coastal maritime traffic.

AIS devices are largely divided into vessels (Class-A, Class-B), route marking (A to N AIS), and search and rescue (AIS-START). Here, the AIS device for route marking serves to increase the reliability of the automatic navigation system by providing the position of the route mark and the current function to the ship where the AIS is installed regardless of weather and weather.

On the other hand, as the number of ships with AIS installed rapidly increases and the introduction of AIS to route signs to support safe navigation increases, communication loads in coastal areas such as ports increase, resulting in a problem of deteriorating AIS service quality. As the AIS installed on some route signs has been suspended, measures are required to improve this.

In addition, the current route marking AIS device is a fairly complex hardware structure system, so it is very difficult in all areas such as installation, waterproofing, and low power management. In particular, the price of the product is quite high and due to frequent failures resulting from complex structures, There is quite a difficulty in maintenance.
