| dc.description.abstract | Marine data collection is of great importance because the analytical results based onthe collected data can be utilized for many purposes during the design phase beforesale as well as the maintenance phase of the boat after sale. In this thesis, I havedesigned and implemented a marine data collection and transmission system foryachts. The system can collect data from an NMEA network, a wireless sensornetwork, a custom-made CAN-bus network, and other sensors such as a 9degree-of-freedom inertial measurement units. The collected data is stored both atthe boat and at a remote server. In this design, I use a Pandaboard as the main boardand I also adopt a watchdog to control the Pandaboard. The watchdog is formed byan Arduino Uno, which controls a relay associated with voltage regulators. I have alsoconfigured the Pandaboard as an access point with a fixed private IP address andhave initialed the DHCP functionality. In this way, I can access the Pandaboard as anaccess point and control it freely in its vicinity via another laptop. For long distancecommunication, with a 3G modem, I can transmit the data from the boat to a remoteserver in the lab. The designed system has gone through a rigorous lab test as well asa simulation test via a boat-movement simulator. Afterwards, I install the box on ayacht manufactured by Viknes. Through various testing and boat implementations, Ifind that the system works smoothly and stable. Two groups of students have donesome previous work on this topic in their master theses, but my work are better thanthe combination of their work. My system is also better than the current commercialproduct. The commercial product supports only local data storage while my systemsupports long distance data transmission in addition to local data storage. | nb_NO |
