Research On Vehicle-Mounted Warning System Of Landslide Based On ZigBee Technology

Many unforeseen security risks such as randomness and unexpected geological disastersmountain: mudslides, landslides will bring great security threats.to Vehicles drive n in the harshmountain road. In order to reduce vehicle accidents on the mountain roads, this article proposes aidea of applying the landslide warning system to the vehicle. From the perspective of automotiveactive safety, this warning system capable of monitoring the road and surrounding area’sreal-time scene in order to provide timely warning to users to avoid danger or select other route.Realization process of warning system are as follows: collect the information of monitorarea and after the integration and process the information will be sent to the car monitoringsystem, once the collected abnormal data appear, the voice alarm module will be triggered, userscan also view the monitoring interface information to make a early decision.Consideration of system’s cost stability and effectiveness, choose ZigBee wirelesscommunication technology as the way of information transfer between the monitor area andvehicles. Arranged a right amount of sensor nodes to the monitor area to collect the soil-relatedinformation, and sent via the aggregation node, Choose the JENNIC company’s latest productsJN5168chip as the core processor of sensor nodes and aggregation Prerequisite for effectivewarning is the correct positioning of the node itself, among many positioning technology chooseDV-HOP system as a means of locating and doing related improvements, finally confirmed theeffectiveness of the improved algorithm. through Matlab simulation analysis. A good warningmodel is the premise of development of early warning program,the system choose Verhulstmodel as a critical landslide warning system.Core chip S3C6410of vehicle monitoring system will make comparison between the collectinformation and safety threshold for judging whether to give early warning.The system alsodesigned the voice alarm and monitoring interface of remote monitoring center, finallycompleting the design of the entire system.
