Design And Implementation Of Debris Flow Monitoring And Warning System

The debris flow refers to the heavy rain,snow or formed by landslides and other natural disasters to carry large amounts of sediment and rock flood in the valley or other depth,steep area.Debris flow has the characteristics of sudden and fast flow,large flow,large capacity and strong destructive force.Debris flows often destroy highway,railway,transportation facilities and even villages,causing huge losses,which made the government and the society attaches great importance to the work of natural disaster monitoring and early warning.With the development of wireless sensor network technology,nowadays,it has been applied in many fields,such as ecological environment monitoring,traffic monitoring,military observation and supervision,especially in the environmental monitoring.The traditional method of debris flow monitoring is mainly through manual observation and video monitoring,which the cost is high.But through the wireless sensor network to monitor the debris flow can not only work for a long time in the harsh field environment,also do not need to send a large number of personnel on duty,at the same time,the data collection is large and easy to deploy.Aiming at the above problems,this paper deeply studies some key technologies of wireless sensor networks in geological monitoring and introduces a new scheme of debris flow monitoring using wireless sensor networks,through using a variety of sensors of different acquisition,soil texture,water content,vegetation coverage,lithology and slope monitoring data.Then the collected data will be collected and transmitted to the monitoring center,the monitoring center receives the corresponding alarm information after processing the monitoring data.In order to analyze the collected data,this paper designs and implements a debris flow monitoring and early warning system based on ExtJS,the system front modules are:state monitoring,map editing,alarm list,contact management module.The background modules are:system management,data management,monitoring point index entry,alarm management module.The monitoring system can collect the relevant indicators of the sensor data to the corresponding alarm information to judge,choose whether to publish early warning according to the alarm level,the administrator through the query alarm information can be informed in advance of the debris flow risk information in the monitoring area,and can realize the sharing of inter departmental information,meet the early warning mechanism for information sharing requirements.
