  • 本研究主要分為三大部分,第一部分為航程資料紀錄器(Voyage Data Recorder, VDR)與無線通訊模組之整合與測試,使VDR定時回傳船位,岸上監管單位便可隨時掌握船隻動向;無線通訊模組包含衛星通訊模組與全球行動通訊(Global System for Mobile Communications, GSM)模組,透過訊號強度的判斷,沿近海時使用GSM通訊模組,GSM訊號不佳時自動切換使用衛星通訊模組。
    第二部分為航程資料的分析,利用點與多邊形相關之演算法,從航程資料中判斷船隻進出港口的時間、港口名稱、航次耗時、航行最遠距離、航行累積距離以及航程資料紀錄狀況,並建立資料庫儲存分析結果。
    第三部分則是運用相同之演算法至現有設備中,可分為兩類,第一為漁船越界警報系統,透過船上電腦或是工業電腦接受GPS資訊,判斷船隻是否闖入他國經濟海域中,響起警報提醒船員或通知岸上監管人員,避免海上衝突或是漁民的財物損失;第二則為航程資料讀取站(Voyage Data Receive Station, VDRS)加入可過濾某特定範圍內航跡紀錄點之功能,避免不肖漁民非法溢領補助油料。

    There are three major parts in this paper. The first part is the integration of a voyage data recorder (VDR) with wireless communication modules. The integration includes hardware assembling, software coding, and testing on a real ship. By adding in the wireless communication modules, the VDR will be able to send back boat’s position at regular time intervals, allowing on-shore spectator to be easily aware of boat’s situation on the sea. The wireless modules include the satellite communication module and the global system for mobile communicate (GSM) module. The VDR is able to automatically select the module to send back messages depending on the strength or the availability of signals. Generally, when a boat is close to shore or in the port, positions are sent back through GSM module. If the GSM signal is bad, usually away from shore or on the middle of ocean, VDR will use the satellite communication module instead. By using this type of communication, the cost will be less than only using the satellite communication onboard.
    The second part is to analyze the voyage data from 2006 to 2013 by using the algorithm to verify whether it is a point in the polygon or not. Through this method, the voyage data will be transferred into several properties, such as the entering/leaving time, the name of the port, the total time of a single voyage, maximum displacement in the voyage, total traveled distance, and the VDR recording status. Those properties will also be saved in a database.
    The third part is applying the algorithm similar to the one in the second part to present devices. This part can be classified into two types. The first one is to create an area-crossing alarm system. By using the onboard computer or the industrial computer to receive global positioning system signal, it will help determine whether the boat breaches in other countries’ exclusive economic zones (EEZs) or not. If the boat crosses the border, the alarm will sound to notify the crew, or the system will automatically send a message to on-shore spectators, avoiding conflict between nations or reducing financial losses of fishermen. The second one is adding a similar filtering function into the voyage data receive station (VDRS), allowing spectators to exclude the voyage data in specific area, in order to prevent the defrauding of fuel subsidies.
