摘　　要：为解决目前水质监测存在的单点测量、实时跟踪观测不及时、通信距离短和供电不便等问题,设计了基于水声通信的海洋水质多点监测系统。该系统主要包括浮标系统、坐底式水质监测系统、岸站实时数据接收系统。水质多点监测的下位机由浮标系统和海底多个坐底式水质监测系统组成;坐底式系统与浮标之间采用水声通信的方式实现水下数据上传,水声通信半径能达到10 km;以浮标作为中继系统,采用太阳能供电,利用DTU和北斗双通信将分钟数据实时传输,解决了诸多水质监测中现存的问题。研究表明,本系统数据实时上传率达到95%以上,能够满足大范围海域内水质多点实时监测的要求,可为水产养殖提供全天候有效可靠的水质参数。A multi-point monitoring system for marine water quality was designed based on underwater acoustic communication in order to solve the problems of single point measurement,and real-time tracking and observation,short communication distance and inconvenient power supply. The system is primarily comprised of buoy system,water quality monitoring system of sitting style,and real-time receiving system of shore station. The lower system of water quality multi-point monitoring includes the buoy system and multiple water quality monitoring system of sitting style,and the underwater data communication between underwater system and buoy is realized by underwater acoustic communication,whose radius can extend to 10 km. Buoy as a relay system powered by solar energy uploads minutes data by double communication of DTU and the Beidou,dealing with the issues of short communication distance,power supply inconvenience,and untimely observation. Shore station receiving software acts as displaying minutes of data,formatting the curve,and saving the data. The system with more than 95% data upload rate can meet the requirements of a wide range of water quality multi-point monitoring in real-time,and provide aquaculture with effective and reliable water quality parameters all day.
