碩士 / 國立交通大學 / 土木工程學系研究所 / 85 / Establishment of long time oceanographically data for seashores and ocean
s is important because it provides the information much needed for sea shores
and oceanography engineering. In addition, wave observations, tides, ocean t
opology and ocean physics researches are essential to the exploration of the s
ea,military use, meteorology and weather forecast.
The automation of sea exploration can save tremendous amount of resource
s and allocations as well as the time that is necessary for traditional approa
ch to oceanography. Most importantly, it solves the difficulty of observation
in extreme weather and thus avoids exposing researchers to danger. The autom
ated data collection and, once collected, the data will be transmitted throug
h radio , which will then process the data .
The setup is as follows: Real-time Global Positioning
System (GPS) will trace
the portable sensors inside the floating objects . Then the transmitting sig
nals from the floating objects will go through a series of TNC signal packet.
These signals will be transmitted by single radio channel back to an observato
ry. Besides, the other channel used to transmit the remote commands which will
be decoded to control all of the gear inside the water-craft. With the GPS gi
ving its precise location , this remote carrr can follow a preset route automa
tically.
This research uses an Electric Map converted from the
standard Taiwan Map released from Departm
ent of Interior Affair. In addition, the WGS 84 are converted to GRS 67 coord
ination system , then the location of the floating objects and the oceanograph
ically data can be deduced.
Based on those related techenologies , the system was set
up in experimental field's tr
ial and after proceed the results of experiment , this thesis gives some concl
usions and suggestions for advanced research and development in the future.
