摘要
建筑用塔吊倾斜度监测是建筑施工单位重点关注的安全问题,利用无线网络实现塔吊倾斜度监测需要解决传感器节点测量数据的丢失难题。为此,提出一种适合于多塔吊倾斜度监测的无线网络动态路由控制策略。传感器节点根据自身与汇聚节点的链路健康状态、邻居节点通信链路优劣,并分析潜在中继节点与汇聚节点正常通信的概率,结合节点工作时隙分配机制,选择一条合适的通信路径将其测量结果可靠地发送到汇聚节点。仿真分析和现场测试结果表明该路由控制策略能够有效降低测量数据丢失情况,满足多塔吊倾斜度监测要求。
Construction crane inclination monitoring is an important issue that many construction enterprises concern. Data loss is one of the major challenges in the inclination monitoring with wireless networks. A new dynamic routing control strategy for wireless networks is proposed to monitor the inclination of multiple cranes. According to the com- munication link state between the node itself and the sink node, and the link quality of its neighbor nodes, the sensor node analyzes the normal communication probability of the potential relay nodes that communicate with the sink node, and combines the time slot allocation mechanism for the sensor nodes, and then selects a suitable communication routing through which the measured results can be sent to the sink node reliably. Simulation analysis and field test results show that the routing control strategy can effectively reduce the measurement data loss and meet the monitoring requirements of multiple crane inclination monitoring.
