Research On Technology And Methods For Forest Fire Video Monitoring

Forest fire monitoring is an important portion of operations for fire fighting, This paper puts forward a new video surveillance system which based on wireless transmission technology. The main conclusions and achievements are as follows:This paper uses some trains of thought and methods for choosing construction sites employed by the departments of communications and municipal administration to introduce some useful conclusions from the disciplines of topography, botany and forest fire-prevention science into geographic information spatial analysis. Through the space analysis of the data on the slope direction, gradient, elevation and compartments of the Jiufeng National Forest Park, we have decided on the construction-sites of forest fire video monitoring spots and derived a conclusion that the number of video monitoring spots for the Jiufeng National Forest Park should be no more than four. This paper may provide some useful experiences for future forest fire video monitoring project.This paper is for the purpose of studying the forest fire video monitoring system installed on the watch-towers as the basis of hardware by using a data retrieval technology from the single watch-tower on the geographical information technology platform. As is known, automatic fire spot locating is of great significance to the forest fire control and video monitoring system .Therefore, it has become a great need to solve the problem of fire spots locating under the condition of a single monitoring spot. We have tried to use the methods to locate the spots on the terrain profile of DEM layer with the help of the search step interpolation function under different slope gradients. Then the curve fitting method can be used to study the changing characteristics of mountain terrain. By taking into full considerations the judgment of fire spot coordinate under various conditions, it would become possible to reach different convergence criteria. Next software programming can be made based on the aforementioned fire spot locating algorithm to collect and input the multiple data spots in DEM into the software to conduct the fire spot locating verification test. Both field trials and practical application show that the accuracy of this method can meet the actual demand for its designated duties and is expected to play an important role in upgrading China's smart forest fire emergency command and management.This paper presents a combined program of double-point positioning method and single-point positioning method, in which such advanced software technologies as component GIS, ArcSDE database engine and NET are employed in a comprehensive way to design and develop the forest fire disaster positioning system for Jiufeng National Forest Park, solving the urgent problem of ignition point on-site positioning currently confronted with the forest fire prevention grassroots management.This paper introduces the quantize design principle for realizing H.264 video codec standard and has designed in hardware description language (Verilog HDL) its hardware circuit using the pipeline and look-up table. The hardware modules of the quantize can process in parallel. Its simulation on QuartusII 6.0 platform indicates that the maximum operating frequency of the quantizer has reached 106.69MHz and can thus meet the real-time video data processing requirement.
