摘要
库岸滑坡监测区域常处于偏远地带,这些区域环境复杂、通讯网络差,无法满足监测工作中数据传输的通信需求,而使用北斗短报文技术可发挥其通信全球覆盖的独有优势.本文针对无信号覆盖地区的滑坡监测数据远程传输问题,提出北斗短报文通信方案,以三峡库区香溪河流域的白家包滑坡为例,建立了白家包滑坡的物联网监测系统,分别对系统的硬件组成和软件程序进行设计.该系统集合了无线传感器网络与北斗短报文两种无线通信技术,以CC2530射频芯片为核心,采用ZigBee802.15.4协议组建无线传感器网络结构,在数据汇聚节点上接入北斗短报文模块,形成了滑坡监测的物联网体系,实现了在通信盲区滑坡监测数据的采集和无线远程传输.
The monitoring areas of reservoir bank landslide is often located in remote areas,where the environment is complex and the communication network is poor,so it cannot meet the communication demand of data transmission in the monitoring work.However,using Beidou short message technology can give play to its unique advantages of global communication coverage so that this technology can meet the above demand.In this paper,a Beidou short message communication scheme is adopted to solve the data transmission problem in remote areas.Taking the Baijiabao landslide as an example,a monitoring system for the Baijiabao landslide is established based on the Internet of things,and the hardware and software components of the system are designed respectively.The system integrates two kinds of wireless communication technology:wireless sensor network and the Beidou short message.In the hareware,this system takes CC2530 RF chip as the core,adopts ZigBee802.15.4 agreement to form a wireless sensor network structure,and connects the Beidou short message module on the data gathering node.Finally,the Internet of things system for landslide monitoring is formed,which realizes the acquisition and wireless remote transmission of landslide monitoring data in the communication blind area.
