【摘要】：近年來隨著近海海洋的過度開發(fā)、海洋污染等，使得海水的溫度有著非常顯著的變化，又如春夏交替時個別海域江河匯流，海水的溫躍層溫度變化亦非常明顯，這些都對海洋牧場中的魚、蝦、貝類和海參等有著非常大的影響。而海水溫度的剖面變化對海洋牧場中生物有著多么重要的影響成為迫切需要解決的技術(shù)性課題。 海洋資料浮標是目前我國海上環(huán)境監(jiān)測的主要手段，近幾年大規(guī)模的業(yè)務(wù)化應(yīng)用，為我國海洋環(huán)境監(jiān)測和災(zāi)害預(yù)警發(fā)揮著重要作用。海洋資料浮標能夠長期、定點、連續(xù)、實用和全天候自動觀測海洋水文氣象等變化趨勢。 本論文所介紹的浮標觀測系統(tǒng)，是一種小型輕質(zhì)浮標控制系統(tǒng)，致力于為大連獐子島漁業(yè)集團周邊海域而研發(fā)的梯度水溫定點浮標觀測系統(tǒng)。在控制終端系統(tǒng)設(shè)計中,因系統(tǒng)要求整體功耗偏低,C8051F系列單片機是一個最佳的選擇。它們擁有靈活的時鐘硬件,使系統(tǒng)能夠方便地在高效運作模式與低功耗模式間進行轉(zhuǎn)換,智能的電源管理模式能夠在正常工作及待機狀態(tài)自由切換,從而降低整個系統(tǒng)的能量損耗;當工作頻率低于10kHz時,時鐘丟失檢測器(MCD)能夠引發(fā)系統(tǒng)產(chǎn)生復(fù)位,確保系統(tǒng)工作的安全可靠。
[Abstract]:In recent years, with the overexploitation of the offshore ocean and marine pollution, the temperature of seawater has changed significantly, such as the confluence of rivers and rivers in individual sea areas in the alternate spring and summer, and the temperature change of the thermocline layer is also very obvious. All of these have a great impact on fish, shrimp, shellfish and sea cucumbers in marine pastures. However, the influence of sea temperature profile on organisms in marine pastures has become an urgent technical issue to be solved. Marine data buoys are the main means of marine environmental monitoring in China. In recent years, large-scale operational applications have played an important role in marine environmental monitoring and disaster early warning in China. Marine data buoys are capable of long term, fixed point, continuous, practical and all-weather automatic observation of marine hydrometeorological trends. The buoy observation system introduced in this paper is a small light buoy control system dedicated to the research and development of the gradient water temperature fixed-point buoy observation system for the waters around the Dalian Swertia Island Fisheries Group. In the design of the control terminal system, C8051F series single chip microcomputer is the best choice because the overall power consumption of the system is low. They have flexible clock hardware to enable the system to easily switch between efficient operation mode and low-power mode, and intelligent power management mode can switch freely in normal working and standby state. When the working frequency is lower than 10kHz, the clock loss detector (MCD) can cause the reset of the system and ensure the safety and reliability of the system.
