摘要
疲劳监测是维护深水隔水管安全和完整性的重要手段,其难点在于多测点疲劳参数的高效传输。针对这一问题,提出了并行协作空时复用(Parallel Cooperation Spatial Time Reuse,PCSTR)的疲劳参数传输方法。PCSTR法以隔水管单测点疲劳参数远距离可靠传输为基础和前提,通过数据包并行传输、节点协作和数据包合并等关键技术实现疲劳参数高效传输,其性能可由传输时延、吞吐量和系统能耗等指标评价。通过试验检验了该方法的可靠性;数值试验也显示了该方法较时分复用(Time Division Multiple Address,TDMA)法,在时效性和能耗等方面具有更好的效果;水池模拟试验证明了水声协作传输的可行性。PCSTR为深水隔水管多测点疲劳数据传输提供了新方法。
Fatigue monitoring is an important measure for maintaining the safety and integrality of deep water marine risers,whose difficulty lies in highly efficient data transmitting of fatigue parameters at mult-Smeasuring points.PCSTR （parallel cooperative spatial time reuse） method was proposed to meet the said problem.Initially,the PCSTR method,which based on the reliable data transmission with long distance for fatigue parameters of single measure point of deepwater riser,achieves efficient data transmitting of fatigue parameters by means of packet parallel transmitting,node cooperating and packet fusion.Meanwhile,the performance of PCSTR has been assessed by transmission delays,throughput and total energy consumption.Finally,trials were carried out to verify the PCSTR＇ s performance.Numerical simulation results showed that the proposed PCSTR method outperformed significantly TDMA in terms of timeliness and energy consumption.The feasibility of underwater cooperative communication was verified via a pool trial.Thus,PCSTR is an effective method for efficient data transmitting at multi-measuring points in deep water riser fatigue monitoring.
