Research on Automatic Landslide Monitoring Data Acquisition System based on Internet of Things Technology

针对传统滑坡监测数据采集系统布线困难、自动化程度低、成本高等问题,设计了一种基于物联网技术的滑坡监测数据自动采集系统。该系统以ZigBee无线传感器网络、无线通信技术为核心,通过布置在滑坡体上的传感器节点采集数据。利用ZigBee协议和互联网将数据实时传输到监控中心,使相关工作人员及时掌握滑坡体信息。以三峡库区八字门滑坡为例,分析了该滑坡当前监测手段的不足,建立了八字门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。针对节点能量供应和数据远程传输问题,提出将太阳能供电系统和北斗短报文模块应用到数据采集系统来弥补野外条件的不足。结合八字门滑坡的地形地质条件,优化了滑坡测点的布置方案,并开发了数据采集界面以实现监测数据的自动采集和直观显示。

Aiming at the problems of traditional landslide monitoring data acquisition system,such as difficulty in wiring,low automation and high cost,an automatic acquisition system for landslide monitoring data is designed,which is based on Internet of Things technology.The system focuses on the ZigBee wireless sensor network and wireless communication technology,collects data through sensor nodes arranged on the slope.And then,it transmits the data to the monitoring center in real-time by the ZigBee protocol and the Internet so that the relevant staff can timely grasp the landslide information.Taking the Bazimen landslide in the three gorges reservoir area as an example,the shortcomings of the current monitoring means are analyzed.The Internet of things monitoring system of the Bazimen landslide is established,the hardware composition and software design of the system are also designed in detail.For the node energy supply and data remote transmission,it is proposed to apply the solar power supply system and Beidou short message module to the data acquisition system,making up for the shortage of field conditions.Combined with the topographic and geological conditions of the Bazimen landslide,the arrangement scheme of landslide monitoring points is optimized,and the data acquisition interface is developed to realize automatic collection and visual display of data.
