为提升地质灾害监测能力,提出一种基于物联网地质灾害监测方法,并开发其硬件、软件系统。该系统由感知层、网络层和应用层组成,感知层采用无线传感网络技术将地质灾害监测(以地表位移、地表倾斜角、降雨量为例)传感器进行组网通信,实现对监测区域的全方位感知与控制;网络层由GSM和北斗卫星通信网络构建,实现监测数据的双向传输;应用层基于B/S架构,实现监测数据管理、提供友好人机界面以及预警信息发布。基于该系统,建立贵州省赫章县乌木铺岩质高边坡地质灾害监测示范站,近4年的运行结果表明:监测数据准确,信息传输稳定,整体性能良好。该系统已在贵州、四川两省进行推广应用。
In order to improve the geological hazard monitoring ability,a method based on IoT (internet of things) and WSN(wireless sensor network) is put forward and hardware and software system is developed for it. The system consists of a sensing layer, a network layer and an application layer. The sensing layer uses WSN to have networking communication between geological disaster monitor sensors such as surface displacement,tilt angle and rainfall to have an omni-directional perception and control of the monitored area. The network layer is composed of GSM (global system for mobile communications) and BDS (Beidou navigation satellite system) and it realizes bi-directional data transmission. The application layer, a B/S architecture -based layer袁 manages monitored data, provides a friendly human -machine interface and releases warning information. With the system, Wumupu high rock slope geological hazards monitoring demonstration station in Hezhang county, Guizhou province was established. The running results in recent 4 years show that the system monitors data accurately and transmits data stably and it has been widely applied in Sichuan province and Guizhou province.
