摘　　要：为实时掌握海洋牧场环境参数的动态变化和养殖生物的活动状态,采用海洋环境因子及水下影像采集和传输技术,以自制浮标平台为载体,在有效解决多路传感器数据并行采集及远程传输、水下摄像头承载装置的防水密封、水下影像数据远程传输等关键技术的基础上,研发了海水养殖环境信息综合监测系统。结果表明:该系统同时调用多个串口进行数据采集,能保证在一个时间节点上多参数水质数据的及时采集和准确性;采用丁腈橡胶材料构成的压紧螺母式电缆密封装置能有效防止海水的渗漏和腐蚀;解码板的分辨率设置为QCIF或者CIF模式,最大码率设置为120 kbps,帧率设置为8~15时,图像的流畅和清晰度较为适中。研究表明,该系统可用于海洋牧场水环境因子监测和水下养殖生物实时监测。A comprehensive monitoring system was developed for real-time acquiring mariculture environmental in-formation and real-time observation of cultured living beings and behavior in sea ranching. In the system,all sen-sors and other components were carried on a homemade buoy platform,and some key technical issues were effec-tively resolved including multi-sensor signals data parallel acquisition,remote transmission of data and underwater videos and camera waterproofing ＆ O-ring sealing. Th e trials showed that simultaneous calling multiple serial ports for data collection ensured timeliness and accuracy of multiple water quality parameters data acquisition. Utilization of nitrile rubber as sealing materials effectively prevented the water leakage and corrosion,and observation of rela-tively smooth and clear picture were conducted by setting decoding resolution option to QCIF or CIF mode, with maximum bitrate of 120 kbps and frame rate of 8-15. The findings can be used in real-time observation of underwa-ter cultured organisms and environment monitoring in sea ranching areas.
