Design And Implementation Of A Class Of Landslide Monitoring System Based On C# Development Environment

Landslide is the most extensive and most serious geological disaster which human face.In order to reduce the harmful effects of landslide and protect people's life and proverty,this paper designs a landslide monitoring system based on satellite positioning and wireless sensor network to realize unattended all-weather monitoring in the area where landslides ofen happen.Comparing with traditional landslide monitoring systems,the designed system in this paper not only realizes real-time monitoring,but also avoids poor permeability and the limit of geographical conditions.Besides,the system has advantages of high precision and being prone to automatization.The landslide monitoring system includes two aspects:the hardware part and the software part.Among them,the hardware part includes terminal nodes,routers and coordinators,which is responsible for collecting satellite positioning information and transmitting it to the control center.Landslide monitoring software is used to summarize and analyze the data.Landslide monitoring software is an important part of the landslide monitoring system.According to the requirements of landslide monitoring,the software has achieved many functions,such as data analysis,information presentation,node control,motion alarm,and so on.Landslide monitoring software is designed based on the.NET Framework using the C# developmentlanguage.This paper elaborates the functional requirements,module design and system realization of landslide monitoring software.In order to improve the system accuracy,an landslide warning algorithm based on sliding mean filtering and first order forward difference is proposed.The most reasonable threshold is obtained by field experiment,which makes the algorithm more effective.This paper also designs shell and bracket for the node to achieve the requirements of beautiful appearance,being easy to install,and applying to variety of slope.
