Based On The Research And Design Of ZigBee And GPS Disaster Monitering System

In recent years,with the rapid development and wide application of computer technology.Internet technology and wireless communication technology.wireless sensor network has become a very popular front topic and research field in the world.Because ZigBee technology has the advantages of low power consumption,low cost,low rate,close distance and large network capacity.It has become the focus of wireless sensor networks.It is mainly used in industrial control,automotive and agricultural automation,consumer electronic equipment.That is medical equipment and medical health,military control,smart home,natural disaster monitoring,early warning and other fields.GPS global positioning technology will be the satellite navigation technology and modern communication technology combined with full time,all-weather,high precision,provide continuous real-time navigation,positioning and the characteristics of differential global positioning technology to eliminate the system error between nodes in order to improve the positioning accuracy and spatial positioning technology has brought a row times change and new applications.In this paper,collapse,landslide and debris flow,deep displacement,underground water level and water temperature changes,relative displacement,surface rainfall,smoke and other disaster location,transmission and handling of the problem is analyzed and researched.Based on the introduced ZigBee network and GPS technology,and then the ZigBee wireless network technology and GPS global positioning technology,wireless sensor network field information acquisition and transmission,and real-time transmission of data,and fast GPS node coordinate information and collect information collected to the remote monitoring center for analysis and processing.To achieve fast positioning,short message communication and precision timing.Thus,according to the types of disaster categories and the types of derivative disasters,disaster information,decision-making and suggestions,disaster warning information and disaster prevention measures needed by the governments at all levels will be produced in a timely manner.
