Research on Early-Warning System for City Environment Based on Sensor Network

Abstract

Aiming at enhancing real-time controlling and continuity of city environmental monitoring and early warning, solutions based on sensor network are proposed. Making ARM as the main processor, bedded intelligent measuring and controlling unit is employed for programming under Linux environment. With PC as the control center, programming in ASP.NET enables complicated processes as data screening, analysis and early warning being achieved. Taking advantage of the GPRS technology, the wireless sensor network is constructed, which facilitates the connection between control unit and center, leading to the establishment of command control and data transmission. Further practical application also demonstrated that such solution is stable, efficient and economical.
