本文描述了一种部署在沿海沙丘上的异质无线传感器网络(WSN)的体系结构，其目的是提供物理参数的实时测量，以更好地确定与风沙过程有关的泥沙输运。无线传感器网络集成了不同类型的传感器，并提供本地和远程连接。特别是，网络中集成了三种不同类型的传感器：多层风速站，为测量沙丘水平而开发的临时传感器，以及能够测量被困沙子的重量和数量的沙子收集器。每个传感器节点至少由一个ZigBee无线电模块组成，该模块能够在大约100米的距离内传输传感器收集的数据。虽然沙位传感器和收砂器只有这个传输模块，但风速站还集成了负责数据处理的微处理器板。还开发了用于远程数据传输的具有GSM连接的网关节点和用于本地通信的Zigbee无线电模块。该节点负责收集传感器节点发送的所有数据报文，并通过GPRS连接将其传输到远程服务器。已经设置了一台Web服务器来收集这些数据包并将其存储在数据库中。建议的无线传感器网络可以提供作用于沿海沙丘的沙子输送过程的静态和动态框架。
In this paper, the architecture of a heterogeneous Wireless Sensor Network (WSN) to be deployed on coastal sand dunes is described, the aim of which is to provide real time measurements of physical parameters to better define the sediment transport in connection with Aeolian processes. The WSN integrates different typologies of sensors and is provided with both local and remote connection. In particular, three different typologies of sensors are integrated in the network: a multilayer anemometric station, a sensor developed ad-hoc to measure the sand dune level and a sand collector capable of measuring the weight of trapped sand and its quantity. Each sensor node is made up at least of a ZigBee radio module that is able to transmit the data collected by the sensor at a distance of about 100 meters. While the sand level sensor and the sand collector are provided only with this transmission module, the anemometric station also integrates a microprocessor board in charge of data processing. A Gateway node provided with a GSM connection for remote data transmission and a Zigbee radio module for Local Area communication has also been developed. This node is in charge of collecting all the data packets sent by the Sensor Nodes and transmit them to a remote server through GPRS connection. A Web server has been set up to collect these packets and store them in a database. The proposed WSN can provide both a static and a dynamic framework of sand transport processes acting on coastal dunes.
