摘　　要：传统的机场噪声感知存在成本高、环境要求高、稳定性差、维护成本高、系统可扩展性差等问题,为此文中提出了一种基于ZigBee的新型机场噪声感知模式。该模式将成本低廉的传感器节点按密集非均匀的泛网格状布置于机场内部及围界,进行噪声数据采集并通过ZigBee网络经由路由节点发送至协调器节点进行汇总及处理,协调器节点经过移动网络传送给中心处理平台,从而实现对机场噪声情况的全面、可靠、准确的监控和管理。文中还提出了一种适用于新型机场噪声感知模式的泛网格化感知节点布局方法,并通过一系列实验分析确定了新型机场噪声感知模式中ZigBee感知节点布局方案。并将得到的布局方案应用于天津滨海国际机场,验证结果证实了新型感知模式和泛网格化布局方法的实用性与有效性。In this paper,present an improved grid-enabled airport noise monitoring method based on ZigBee,as traditional airport noise monitoring method has several problems including high cost,environmental requirements and maintenance,poor stability and system scal-ability. The proposed method widely deploys sensor nodes with low cost in the airport and its surrounding areas as grid,the sensor nodes monitor noise and transmit data via ZigBee,the coordinator nodes receive data from router and sensor nodes,and then upload noise data to the processing center through the mobile or wired network,achieving the overall,reliable and accurate monitoring and management for airport noise. In this paper,also put forward a generic grid node layout method applicable to the new airport noise aware of patterns,and through a series of experimental analysis,determine the ZigBee node layout scheme of perception in new airport noise perception pattern. Apply the layout scheme into Tianjin Binhai International Airport,the verification results confirm that the new perception model and the method of grid layout is practicable and effective.
