Description

Navigational sign management system and method {MANAGEMENT SYSTEM AND METHOD FOR AIDS TO NAVIGATION}

This article relates to a navigational beacon management system and method using narrowband Internet of Things.

AIS (Automatic Identification System) is an automatic ship identification system that transmits navigational information, such as the ship's identification number, location, and course speed, to other ships and the home station on land in real time for the safe operation of ships at sea. This AIS is a device to prevent ship collisions at sea, and is a communication device that the International Maritime Organization (IMO) mandates to be installed on ships over a certain size. The progress of other ships, including the location, course, and speed of nearby ships, can be monitored through AIS. Even when visibility is poor, ships equipped with AIS can be identified, enabling ship collision prevention, wide-area control, and search and rescue activities for ships in distress.

Recently, AIS, which was previously installed for automatic identification of ships, is being installed in navigational beacon facilities. A navigational beacon refers to a facility installed in sea routes, ports, bays, straits, and change points or dangerous areas to help ships navigate through various means such as lights, colors, sounds, and radio waves. In order to remotely monitor and control these navigation aids and efficiently transmit the information collected from the navigation aids, AIS is being applied to the navigation aids. In this way, the device to which AIS is applied to navigation aids is called AtoN AIS.

Previously, route signs were managed remotely using various existing communication methods such as WCDMA and TRS. In the case of this conventional method of remote management of navigation aids, only information exchange between the operation center on land and the navigation aids was possible, so the function was limited to monitoring the status of the navigation aids.

To solve these problems, AtoN AIS was constructed by applying AIS to navigation signs. However, when building AtoN AIS, there is a cost burden due to the high price of AIS, and there is a problem in that the service cannot be provided to small ships that are not equipped with an AIS receiver. In addition, unnecessary information may be immediately received by the ship through the AtoN AIS service. In other words, a large amount of AIS information for navigation signals is received together with the ship's AIS signal, which may cause confusion for managers and users.

Further comprising receiving the AIS data and broadcasting it through the NB-IoT base station,
The second route beacon converts the marine environment information collected through the sensor into the AIS data and transmits it to the AIS base station, and the AIS base station transmits the AIS data received from the second route beacon to the AIS service platform device through the AIS network. Method of transmitting and managing navigational signs. delete In paragraph 13:
The step of transmitting the data is,
Upon receiving a transmission request for data of the first route sign and the second route sign from a ship, transmitting the stored IoT data and the AIS data received from the AIS service platform device to the ship,
A route sign management method in which the vessel is equipped with an NB-IoT terminal capable of transmitting and receiving the IoT data.
