北斗多模定位与传感网络集成的高精度形变监测设计及分析

北斗导航系统正在为亚太地区提供服务,并将逐步实现全球覆盖,未来将在测绘、交通、监测等众多领域发挥重要作用。本文主要探讨BD/GPS双模高精度定位,并以广东省清远市飞来峡大坝为例,设计形变监测网,集成Zigbee无线传感网,形成自动化形变监测系统,对比分析BD/GPS双模和GPS单模两种定位模式下监测网的可发现最小形变位移的能力,结果表明:BD/GPS双模定位更有利于提高监测网的监测能力。

Study of Design and Analysis for High Accuracy Deformation Monitoring Based on GNSS Positioning and Sensor Network

Beidou Navigation System is providing services to the Asia-Pacific region, and it is gradually to achieve global coverage.It plays an important role in many fields, such as surveying and mapping, transportation, monitoring, and so on.This article discusses hybrid BD/GPS precise positioning.A deformation monitoring network is designed for the dam of Feilaixiain Qingyuan, Guangdong Province.Zigbee wireless sensor network is integrated for communication.So that, an automatic deformation monitoring system is formed.The monitoring capability of deformation monitoring network using BD/GPS and GPS positioning is compared.And results show that the BD/GPS positioning can enhanced the ability of deformation monitoring network.
