梯度水温定点浮标观测系统研究
发布时间：2018-10-19 17:29
【摘要】：近年来随着近海海洋的过度开发、海洋污染等，使得海水的温度有着非常显著的变化，又如春夏交替时个别海域江河汇流，海水的温跃层温度变化亦非常明显，这些都对海洋牧场中的鱼、虾、贝类和海参等有着非常大的影响。而海水温度的剖面变化对海洋牧场中生物有着多么重要的影响成为迫切需要解决的技术性课题。 海洋资料浮标是目前我国海上环境监测的主要手段，近几年大规模的业务化应用，为我国海洋环境监测和灾害预警发挥着重要作用。海洋资料浮标能够长期、定点、连续、实用和全天候自动观测海洋水文气象等变化趋势。 本论文所介绍的浮标观测系统，是一种小型轻质浮标控制系统，致力于为大连獐子岛渔业集团周边海域而研发的梯度水温定点浮标观测系统。在控制终端系统设计中,因系统要求整体功耗偏低,C8051F系列单片机是一个最佳的选择。它们拥有灵活的时钟硬件,使系统能够方便地在高效运作模式与低功耗模式间进行转换,智能的电源管理模式能够在正常工作及待机状态自由切换,从而降低整个系统的能量损耗;当工作频率低于10kHz时,时钟丢失检测器(MCD)能够引发系统产生复位,确保系统工作的安全可靠。
[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.
