摘　　要：提出一种多载波物理层链路汇聚自适应带宽控制技术(MC-ABC)的超长距离海陆微波系统,并在陆地和海洋各选取一个地点进行安装。经过实际现场安装测试结果证实,该系统能成功地解决海上石油勘探、开发领域在使用超长距离海陆微波系统进行信号传输时,存在的由多径反射和折射造成的信号深度衰减问题,并且能大幅度提升海上油气田现有计算机网络的通信带宽和使用效率。相比传统微波通信技术,所设计的多载波链路汇聚的超长距离海陆微波系统具有传输距离远、可靠性高、传输带宽大、网络延时小、使用效率高等优点,在实际测试中取得了良好的效果,此应用在国内海洋石油勘探开发领域尚属首次。A ultralong distance sea and land microwave system based on multi carrier physical layer link aggregation adaptive bandwidth control technology(MC-ABC)is proposed,and one location each on land and ocean is selected for installation.After actual on-site installation,the testing results confirm that the system can successfully solve the problem of deep signal attenuation caused by multipath reflection and refraction when using ultra long distance land and sea microwave systems for signal transmission in the field of offshore oil exploration and development,and can greatly improve the communication bandwidth and usage efficiency of existing computer networks in offshore oil and gas fields.In comparison with the traditional microwave communication technology,the designed multicarrier link convergence technology in ultralong distance sea and land microwave system has the advantages of long transmission distance,high reliability,large transmission bandwidth,small network delay,and high usage efficiency.It has achieved good results in practical testing,and its application is the first in the field of domestic offshore oil exploration and development.
