【摘要】：為解決目前水質(zhì)監(jiān)測(cè)存在的單點(diǎn)測(cè)量、實(shí)時(shí)跟蹤觀測(cè)不及時(shí)、通信距離短和供電不便等問題,設(shè)計(jì)了基于水聲通信的海洋水質(zhì)多點(diǎn)監(jiān)測(cè)系統(tǒng)。該系統(tǒng)主要包括浮標(biāo)系統(tǒng)、坐底式水質(zhì)監(jiān)測(cè)系統(tǒng)、岸站實(shí)時(shí)數(shù)據(jù)接收系統(tǒng)。水質(zhì)多點(diǎn)監(jiān)測(cè)的下位機(jī)由浮標(biāo)系統(tǒng)和海底多個(gè)坐底式水質(zhì)監(jiān)測(cè)系統(tǒng)組成;坐底式系統(tǒng)與浮標(biāo)之間采用水聲通信的方式實(shí)現(xiàn)水下數(shù)據(jù)上傳,水聲通信半徑能達(dá)到10 km;以浮標(biāo)作為中繼系統(tǒng),采用太陽(yáng)能供電,利用DTU和北斗雙通信將分鐘數(shù)據(jù)實(shí)時(shí)傳輸,解決了諸多水質(zhì)監(jiān)測(cè)中現(xiàn)存的問題。研究表明,本系統(tǒng)數(shù)據(jù)實(shí)時(shí)上傳率達(dá)到95%以上,能夠滿足大范圍海域內(nèi)水質(zhì)多點(diǎn)實(shí)時(shí)監(jiān)測(cè)的要求,可為水產(chǎn)養(yǎng)殖提供全天候有效可靠的水質(zhì)參數(shù)。
[Abstract]:In order to solve the problems of single point measurement, real-time tracking, short communication distance and inconvenient power supply, a multi-point monitoring system for ocean water quality based on underwater acoustic communication is designed. The system mainly includes buoy system, bottom-sitting water quality monitoring system and real-time data receiving system of shore station. The lower computer of multi-point water quality monitoring consists of buoy system and bottom water quality monitoring system, and underwater data transmission is realized by underwater acoustic communication between bottom water monitoring system and buoy. The radius of underwater acoustic communication can reach 10 km; using buoy as relay system, using solar power supply, using DTU and Beidou communication to transmit the minute data in real time, which solves many existing problems in water quality monitoring. The results show that the real-time data upload rate of the system is more than 95%, which can meet the requirements of multi-point real-time monitoring of water quality in a wide range of sea areas, and can provide effective and reliable water quality parameters for aquaculture all the time.
