Synopsis: The GIS-based 3D scene visualization integrated accusation platform can realize the flexible allocation of resources and the unified command and dispatch of the fire ground through big data analysis and processing for the collected combat information. Through disaster assessment and prediction, energy efficiency analysis, simulation drills, one-click debugging and other functions, it helps commanders make scientific and reasonable operational decisions and command deployment. After the end of the battle, the combat analysis can carry out through historical records, audio and video materials, etc. Background: In recent years, the safety situation of the petrochemical industry is severe, and the number of major and malignant disasters is increasing, and the traditional voice dispatch and decision-making methods in fire-fighting and rescue have been difficult to meet the command needs of the fire scene. It is imperative to develop an integrated accusation platform, focusing on solving the problems of poor environmental adaptability, low level of intelligent informatization, insufficient collaboration ability, and lack of unified accusations in traditional accusation rescue programs. Design purpose: To effectively solve the practical problems such as unclear fire situation in emergency rescue, inability to transmit audio and video in real time, lack of rear technical support for initial command, no real-time recording of the battle process, and no audio and video basis for battle evaluation, so as to comprehensively improve the level of accusation decision-making in the petrochemical industry.Formal beauty: The platform uses deep blue as the main color, the architecture is clearly layered, the user interface design is simple and elegant, and the design concept of pragmatism, user-friendliness and technological wisdom is integrated, creating a visual style that is both clear and calm, professional and friendly. Functional beauty: The remote intelligent integrated accusation platform of firefighting robot integrates cutting-edge technologies such as Internet of Things, informatization and intelligence, and has functions such as information collection, data management, on-site command, auxiliary decision-making, and efficiency evaluation. Science and technology beauty : Relying on advanced GIS and 3D modeling technology, the platform has successfully built a "digital twin urban fire protection " that accurately corresponds to the real world, providing new scientific and technological support for fire-fighting.
