碩士 / 國立高雄應用科技大學 / 電機工程系博碩士班 / 106 / The purpose of this thesis is to obtain high accuracy tidal data through low-cost, high-mobility, and the high-precision laser rangefinder. Nowadays, the national maritime engineering is rapidly developing, and costs of original equipment are approximately NT$100,000 for the acquisition of tidal data. Setting up tidal gathering stations to acquire a large amount of construction need a larger amount of maintenance funds, and therefore it is resulting in an incomplete data acquisition.
This article uses MSP430 as the core processor with its low energy consumption characteristics and stable computing power, to support easy programming and compatible connection with many peripheral devices of I2C, SPI, Bluetooth, and RS-232 etc. This implementation utilizes such feature to integrate the wireless Bluetooth system linked to the control computer in order to prevent the risk of joint corrosion that may be caused by installing the instruments on the seashore. In addition, through the RS-232 interface, the high precision laser rangefinder and UHF radio equipment are welded on the motherboard to achieve a low cost and high accuracy objective.
After setup the system, the precision performance was a 1% error less than the pressure type tide where the measuring station is located at Kaohsiung Port Authority Pier 10. As a result, all vessels within a radius of 2.2 km are able to receive the real-time tidal data via radio broadcast and get the water depth correction immediately. Therefore, for all the arrival and departure vessels can get the tide date immediately. The tide data can be transferred to the working boats and to correct water depth also. Such implementation will guarantee a higher quality of construction.
