漁船航程資訊系統由安裝在漁船上的航程記錄器（Voyage Data Recorder, VDR）、配置在漁船加油站的航程讀取器(Voyage Data Receive Station, VDRS)以及設置在指定位置負責彙整漁船加油站上傳之漁船補貼時數、航跡等資料，進行統整與分析的彙整中心等三個子系統所組成。此系統應用在漁船的核配補貼用油，並協助漁業年報等相關應用多年，其資訊傳輸主要採用網路方式進行；由於無線傳輸技術的快速發展，安全保密上已有大幅改善，因此本研究將無線傳輸技術應用到漁船航程資訊系統上，主要目的為改善使用上的缺失並增加系統功能應用。
在採用無線技術的類別過程中，考量傳輸距離與容量等因素，使用Wi-Fi傳輸技術做為無線通訊的標準，在現有的VDR與VDRS上分別增加Wi-Fi晶片模組。另外為了增強作業漁法的辨認，在VDRS上新增相機設備。考量到照片像素品質，將嵌入式系統的作業系統從Windows CE升級為較高階的Windows Embedded Standard 2009。
系統具備無線傳輸功能後，首先應用此項技術在VDRS下載VDR內部的航跡數據過程，能夠大幅提升傳輸效率及工作人員操作的安全性。另外在進出港管制站附近設置掃描漁船上VDR的感測設備，能夠準確判斷出漁船的進出港狀況，並將漁船進出港紀錄檔上傳至指定的位置。同時配合地理資訊系統，在漁船返港時可立即將本次出航的航跡數據下載，並即時顯示在地圖上，讓港口管制人員可即時得知漁船的作業海域。這個資訊提供漁業當局人員能夠掌握漁船是否於港口內，有助於漁船位置狀況管理以及後續航跡資料分析。
無線傳輸下載以及照片上傳作業，經過多次測試確認可以正確傳輸。在進出港應用部分，於安平漁港附近空地進行陸上模擬測試以及高雄旗津實際海上測試，包含無線收訊距離以及感測設備偵測，確定可偵測到移動中的VDR，證實研究開發的系統可以正確判斷漁船的進出港狀況。

SUMMARY
Fishing voyage information system composed of three subsystems ‘Voyage Data Recorder (VDR)’, ‘Voyage Data Receive Station (VDRS)’, and ‘Data Consolidation Center in NCKU’. This system is used to calculate subsidies of oil usage and other related applications on fishing boat for many years. The main way to transfer information is by the Internet. It has greatly improved the security and confidentiality, due to the rapid growth of wireless transmission technology. So technology of wireless transmission will be applied in this research.
Our main consideration is distance and capacity of transmission, using Wi-Fi as a wireless communication standard, the existing VDR and VDRS were added Wi-Fi chip module. Furthermore, in order to enhance operations to identify fishing methods, equipment of camera is installed on VDRS. Considering the quality of photo, embedded system upgraded from Windows CE operating system to WES 2009.
This research applied this technology in the downloading process, it can obviously improve the efficiency on transmission and safety of operation of staff. In addition, we set the sensing device near the Check Point to use scan VDR. It can be able to accurately determine the status of inbound and outbound. By using GIS, when fishing boats return to harbor, we can download the track data and show it on the map.
We can confirm that track data which are downloaded by Wireless transmission and photos which are uploaded by cable transmission can transfer correctly. In application of inbound and outbound, we did a simulation in the open space where it is near An-ping fishing port to test. The simulation are include distance of wireless transmission and sensing device, we make sure it can detect moving VDR. Therefore, we prove this the system of the research can determine the condition of inbound and outbound correctly.
Key words：Voyage Data Recorder, Wi-Fi, inbound and outbound

INTRODUCTION
Currently, the data of fishing voyage information systems is transferred by the mode of wired transmission on the part of data transmission. In this process, RJ45 must be connected with VDR by staff who stands on board. We still have a problem, if connector is used in a bad environment for a long time, it will be destroyed. In order to improve this problem, we used wireless transmission technology in this system. It is not only to ensure to transfer data successfully and also solve the distance limit which is from the workstation to the gas station.
The study also use wireless transmission technology to discriminate movement of vessels which enter and leave harbor, and upload the log file to a specified location. We set up camera device in VDRS, when VDRS is used to download track data, the system will automatically take a photo of fishing boat. It can help to identify fishing methods and analysis.

MATERIALS AND METHODS
In this study, consider the transmission distance and capacity factors, optional Wi-Fi wireless transmission technology as standard. The entire system is divided into onshore equipment and equipment on fishing boat. In onshore, we use of embedded systems in VDRS and BIS, and link sensing device(Bridge) and camera, and we placed the VDR and WIFI antenna on fishing boat. In the application, when the boats into the port range, Set up a mechanism within the VDR, it can know whether VDR within the range, and decision to open or close Wi-Fi. As a result, BIS can know inbound and outbound fishing boats through Bridge, and give VDR tag. Using this tag, we can add one kind of way to download data, it only download data between the tags, and merged with GIS. Finally, the track data can be clearly displayed on map

RESULTS AND DISCUSSION
In this study, the measured results and data.
VDR
VDR can be turned on or off WIFI correctly by GPS data during the operation, test near NCKU, experimental data as shown in Figure 1.
Figure 1. VDR regional discrimination
VDRS
In terms of camera tests, version XP of the picture quality is better than version CE, so the camera of version XP is more suitable for identify fishing methods, the picture as shown in Figure 2.
Figure 2. Version CE(left) and version XP(right)
In terms of Wi-Fi transmission, test 99996 data can transfer completely, transmission rate about 100 record/s, and compared with wired transmission, its transmission rate about 450 record/s, results as shown in Figure 3.
Figure 3. VDRS Download Rate
BIS
Test results in Anping and Cijin, if both Bridges can be caught VDR Wi-Fi signals, BIS judge determine the state of fishing boats Inbound and outbound correctly, and during the communication did not leave signal range, tag can be given correctly. Currently required 5~10 seconds to give tag, speed of fishing boat is 5~6 knot in test, tag can be given correctly.

CONCLUSION
In this study, Wi-Fi fishing voyage information system and berth identification system can be correctly linked with the VDR, all data will be transfer successfully through Wi-Fi, and the data be uploaded to NCKU for subsequent data analysis.
