Design and Development of Mobile Monitoring System for Forest Fire Fighting

Abstract

AbstractIn the forest fire scene, the situation is complex and changeable, the front fireman and the rear command center will face the difficulties of field data delay, error transmission and so on, thus reducing the efficiency of fighting and fighting, endangering the life and safety of firefighters. It is necessary to design a device which can transmit the accurate data of the field environment to the rear command center in time, so as to provide the basis for the decision of fire fighting, and then shorten the time of fire fighting and improve the efficiency of fire fighting. According to the characteristics of forest fire, this paper analyzes the demand of information transmission before and after forest fire fighting, and puts forward the design plan. According to the demand analysis and the study of forest fire characteristics, the alternative hardware modules are compared and analyzed to determine the appropriate hardware, and the hardware of each sub-module is integrated and encapsulated to complete the physical design of mobile monitoring nodes. optimize the transmission mechanism in the process of fighting and fighting, so as to improve the efficiency and stability of communication transmission in the process of forest fire fighting and fighting. Based on the data fusion processing of temperature, humidity and smoke concentration, an early warning algorithm for mobile monitoring nodes is proposed. In the laboratory environment, suitable mobile communication technology, virtual simulation software and compilation environment were selected to simulate the monitoring and early warning of forest fire scene. The mobile monitoring device designed in this paper can effectively collect real-time data, including temperature, humidity and smoke concentration, and select the optimal base station and path.KeywordsForest fireRescue sceneMonitoringWireless sensor network
