Abstract of "The research and development of the electronicalized technology and the substitute energy on fishing boats"
一、"On the research and development of the main engine propulsion e-monitoring system for the fishing boat (Ⅱ)":
This project is a two-year project. In the first year, we have established the main engine monitoring system with the human-machine interface and control viewgraph, which equips with the remotely controlled function. The task in the second year is to integrate the main engine system with the propulsion system and steering system, and extend its monitoring functions according to the ship owner requirement. The developing system in this project can automatically receive and transmit the signals and display them effectively on the monitor screen. The wireless internet remotely connected technology is also integrated which can offer the managers on land be able to monitor all the related information through the control interface with dynamic homepage model, Consequently the safety and convenience of the ship navigating at sea can be promoted.
二、"Study and development of an e-monitoring system for fishing boats - Fire detection and oil/freshwater monitoring (II)":
Traditional Ship monitoring system depends heavily on light bulb indicators and switches to turn on/off equipments. During last year, we had achieved and successfully demonstrated the computerized oil/fresh tanks monitoring system and the fire alarm system for temperature and smoke detection. At the end of the work, our work had been integrated with other sub-projects to become a fishing boat monitoring system of its kind, and set up a few improvements to be made for this year’s work. First of all, this year we have tested our system at the Fishing Training II to test the developed oil/fresh water monitoring with success. Extra function for fuel consumption rate recording is also implemented. Secondly, the fire alarm system has been modified without any intermediate signal amplifier between the sensor and our monitoring hardware system, resulting in a more cost effective system. Finally, the warning record of the monitoring system has been rewritten to reduce the hardware system and on board memory requirements. With our newly written computer codes, the DSC module is not necessary for the monitoring system and the entire system take fully advantage of the cFP modules, which can be easily integrated among many sub-systems for the entire project. If there is any ship is willing to cooperate by implement the monitoring system, our system is robust not only in the hardware selection, but also in the software arrangement. It can be also tested by setting one system at the Train Center at Kaohsiung for system testing and technology transfer purposes.
三、"Research of e-monitoring systems for fishing boat's electricity":
It is occasionally heard that accidents of fishing boats happened due to not timely electric monitoring for power panel. Not only does it threaten fishing boats and crew life extremely, but it is also a big loss to ship owner. It is necessary to monitor the ship conditions effectively and immediately in order to find out electric problems in advance. The primary objective of this project is first to establish related information for each control process of electric systems in fishing boats, then to plan and design man-machine interface and monitoring picture, and finally to test with simulated acquisition signals. The suitability of this monitoring system is verified by a real ship test via a shipbuilding plant. This process can reduce the possibility of malfunction of electric systems for fishing boats in order to increase the safety and economy of use of the electric generator.
四、"Preparation and properties of nanostructured coatings for ship bodies (2/2)":
New antifouling paints have been prepared from 5 wt% fluoroalkylsilane modified SiO2 (FAS-SiO2) nanoparticles and 1, 5, 10 and 20 wt% cuprous oxide (CuO2) powder in a silicone resin. The contact angles of these paints were all around 140~150o. Their pencil hardness remained at 4H and their adhesion strength were around 2.1~2.5 MPa. In the toxicity test of organism, the cupper ion content in the internal organs of mouthbreeder were around 20~40 ppm. After salt water spray test, their hardness did not change. In the ocean exposure experiment, the paint with 5 wt% FAS-SiO2 had less aquatic organisms attachment than the paint without 5 wt% FAS-SiO2. Moreover, the attached organisms were easy to remove by water spray. In the water resistance experiment, the sail resistance was reduced 11.5%, and the fishing boat water resistance was reduced 13.8%. In the real boat antifouling test for two weeks, we did not find obvious aquatic organisms attachment on the hull with the paint.
五、"Wind power generation on energy saving of fishing boats":
Since the price of petroleum of the whole world gets higher and higher recently, the cost of the employed fuel oil of fishing boats may be evidently increased. The purpose of this project is to reduce oil consumption and minimize pollution from engine of fishing boats using wind power generation system. This project proposes a wind power generation system to supply the required electricity for battery system in fishing boats. The wind power generation system can generate electricity when wind speed is higher on the sea, and it can also be used to charge battery when engine is not running. The advantages of the proposed wind power generation system can capture wind energy with no pollution, reduce energy consumption, and minimize environmental pollution. This project is to carry out the experimental tests of wind power generation system to effectively save oil consumption of engine on domestic fishing boats.
六、"The installation and testing of fuel cell system for fishing boat":
The fuel cell will be an important new power machine to solve the problem of energy shortage and environment pollution. To use the fuel cell system as a power generator of fishing boat, the guidelines for the use of fuel cell system on board of ships should be followed to monitor and trial the system. The propulsion performance of fuel cell system on fishing boat also require to study further. The results of both fuel cell system and diesel generator system show that two to three power relation of output current to rotation speed can be found in the high speed of propeller. The same relation of output current to ship speed can also be obtained at higher ship speed.
七、"A study on using biodiesel and DME as alternative fuels for diesel engines":
This study use domestic biodiesel fuel of different sources, including sunflower seed, waste cooking oil, and oil of cooking waste, as the alternative fuel for a diesel engine. Engine tests are performed under different loads and speeds to study the fuel consumption and exhaust emissions, while comparing the results with those using fishing boat fuel A.
The results show that the fuel consumption of B100 and B20 biodiesel is higher than that of petroleum diesel. In the aspect of exhaust emissions, the bsCO of both B100 and B20 is lower than petroleum diesel. The smoke expelled by B100 is eminently lower than petroleum diesel. The smoke expelled by B20 is higher under lower engine speeds, while lower under higher engine speeds than petroleum diesel.
Dimethyl ether (DME) may be produced from coal, while possesing the potential of reducing exhaust emissions of diesel engines. It is therefore an important alternative clean fuel for diesel engines. This study fabricates a DME fuel system to provide as a basis for future study.
八、"The pratical study on the feul oil consumption minitoring system thorugh GPS data":
In order to solve the fishing boat oil embezzlement problem, a system to estimate the oil consumption of fishing boats is developed in this study. The outcomes of this system would help government to decide the amount of oil that could be subsidized. This system is composed of GPS record, voyage route recorder and a data collection center. GPS record installed on fishing boat is used to record the voyage route data. Voyage route recorder will be set up in the fishing boat gas station, through which the data translation and encrypting process will be carried out. When gas station is closed, the collected data will be translated to data collection center, and the center will summarize the voyage route data and send it to Fisheries Agency next day. The system is admitted by Fisheries Agency and is put into practice for those boats that are larger than CT3 next year. As the system is applied it is believed that the amount of subsidized oil will decrease and embezzlement situation will improve too. |
