本論文之主要目的在,建立可以攜帶各種的測量海水的水文數據傳感器,使的可以在不同水深運作之一個自動化浮標系統。這個系統包含可抵抗壓力之外殼,內部含有:浮力控制系統、電力提供系統、控制電腦、PLC控制單元、GPS定位系統和無線通訊設備的建置。
設計和製造適當壓力外殼的同時,收集國內、外可供參考論文以及用實驗的方式確認參考論文的適用性。浮力控制系統部分由:步進馬達、滾珠導螺桿和一個活塞缸系統所構成。經過活塞來回作動時候可使系統產生0.5公斤的浮力變化,使整個系統可以自由的做上浮或是下沉的動作。
至於水文的數據的量測,使用壓力計的訊號來提供系統對應的相對水深,而在系統上浮下沉過程利用溫度感測器來執行水溫量測。系統到水底時,如無執行任務時,將自動關掉電源的輸出,使的有效拉長電池可以工作的時效。在斷電數小時過後,電源開關將再次啟動並且著手系統上浮。當系統判別上浮到海面上,將自動收集GPS定位系統的經度和緯度資料。之後收集到的不同數據資料包括:深度,溫度和位置,透過無線通訊設備將資料傳輸回岸上的使用者。此外,無線通訊設備尚有能力傳輸新的任務程式給浮標系統。如此,無須從海上回收浮標系統,直接利用無線傳輸將任務型態過更改。
系統的主要控制系統包括:一台電腦及一部PLC控制器及其各自的控制軟體。 電腦使用Labview 7.0程式為其主要控制程式,在PLC控制器則使用NAIS介面的PLC程式語言來做控制。利用此分散式架構的控制單元,將可有效的控制整體系統的運作。
The main purpose of this thesis is to establish an automatic float system that can carry various kinds of sensors to measure the hydrological data of sea-water at different level of depth. This system contains a pressure vessel within which a buoyancy control system, electric powers, computer, PLC controller, GPS antenna and wireless device are constructed.
To design and manufacture an appropriate pressure vessel, related reference papers are surveyed and confirmations of its feasibility are carried out through experiments. The buoyancy control system includes a stepping motor, a liner screw and a piston. When the piston is pulled back a maximum lost of 0.5kg of buoyancy make the vessel dive. Conversely, the vessel floats up as the piston is pushed out.
As to the hydrological data, with the use of pressure gage to sense the depth and thermal couple to catch the corresponding temperature are executed on both diving process and float-up process. When vessel arrives sea bottom the power will switch off automatically to safe the electric power and to elongate the work duration. After preset hours pass, the power switch will boot up again and proceed to float-up process. When the vessel ascents to sea surface GPS antenna receives the longitude and latitude data automatically. The collected data include depth, temperature and position will then send back to command station through wireless device. Also the wireless device is capable to receive new command sent from the command station. In this manner, without recovering the vessel from the sea area, one can easily change the operation style whenever the vessel is floating on the sea surface.
The main control kernel of the system includes a personal computer, a PLC controller and control software. The software contains two different programs. The Labview 7.0 program is for computer and the other is for PLC controller.
Individual function test for each sub-system is carried out and find out that every sub-system works correctly. In the next step, these sub-systems will be put together to confirm its entire performance. After laboratory tests, field tests will be conducted next year.
