摘　　要：针对混凝土松软程度进行及时报警,关系到水利建设的安全。由于在大型水利设施中,混凝土松软的程度很容易受到地下水流干扰,使无线传感节点监测到的混凝土松软程度出现无规则的波动,造成报警节点出现误判的问题,提出采用信号译码重构算法的大型水利设施混凝土松软程度传感网络报警模型。利用信号译码重构的方法对无线传感节点监测到的疑似信号进行译码与重构,消除水声干扰信号造成的影响,获取准确的混凝土松软程度信号,设置中继节点为参考节点,根据信号在水中传输情况,随着距离衰落的特性计算报警节点的空间位置,实现混凝土松软程度报警节点的准确定位。实验结果表明,利用改进算法能够实现大型水利设置中混凝土松软程度的准确监测。Timely alarm of concrete soft degree is related to the safety of the water conservancy construction. In large water conservancy facilities, concrete soft degree is vulnerable to the interference of groundwater flow, making random fluctuations of using wireless sensor nodes to detect concrete soft degree, which leads the misjudgment problem appeared in alarm nodes. A sensor network alarm model of concrete soft degree in large water conservancy facilities was proposed using signal decoding reconstruction algorithm. We used the method of signal decoding reconstruction make decoding and reconstruction for suspected signal detected by wireless sensor nodes, eliminated the effects of acoustic jamming signal, and obtained accurate signals of concrete soft degree. The relay node was set as the reference node, according to the transmission status of signal in the water, the spatial location of alarm node was calculated according to the features of distance decay, to realize the accurate positioning of alarm node of concrete soft degree. Experimental results show that using the improved algorithm can achieve the accurate monitoring of concrete soft degree in large water conservancy project.
