The Application of Wireless Sensor Network Technology in Earthquake Disaster

Abstract

Wireless sensor network technology is brought in the earthquake disaster protection. A dynamic, real-time and changeful earthquake disaster wireless monitoring system is constructed so that it could meet the each requirements of environmental monitoring which has great significance to the earthquake hazard prediction. In the paper, the sensor input interface and equipment control output interface are designed, the acquisition of scene information and front-end wireless nodes of equipment control are developed, utilizing ARM9, expanding various resources interface to be the host hardware of monitoring system, using monitoring function and man-machine interface in the workbench of Linux operating system, through unified coordination command to the front-end wireless nodes to finish the collection and analysis on environment information and comprehensive control of equipment. The system has the characteristic of low cost, strong commonality and expandability, high reliability. It can be easily applied to the environmental monitoring on various occasions to meet customers' different needs.
