智能封堵器在水下海底管道的维修工作中起到了不可磨灭的作用。为了实现封堵器海洋工作环境中的无线遥控动作,封堵器海底工作中采用了水声通信技术。整个水声通信过程可以归结为首先由PC机发出指令给Modem,经功率放大匹配后送至水声换能器,水下部分按逆方向接收。对水声通讯频率的选择及水声换能器的选型进行了研究,并利用中国科学院水声研究所研制的FSQ-37型水声换能器,进行了换能器性能测试试验,确定了水声通讯的载波频率。水声通信技术的研究将会改善海底石油管道水下维修时通信的稳定性和可靠性。
Intelligent occluder plays an indelible role in the maintenance of underwater submarine pipelines. In order to realize the wireless remote control action of occluder offshore working environment, underwater acoustic communication technology is adopted in the seafloor of occluder. The entire underwater acoustic communication process can be attributed to the first PC to send commands to the Modem, amplified by the power amplifier to send acoustic transducers, the underwater part of the reverse direction to receive. The frequency of underwater acoustic communication and the selection of underwater acoustic transducers are studied. The transducer performance test is carried out by using the FSQ-37 underwater acoustic transducer developed by Institute of Hydrology, Chinese Academy of Sciences. The underwater acoustic carrier frequency. Research on underwater acoustic communications technology will improve the stability and reliability of communications during underwater maintenance of subsea oil pipelines.
