[0002] Currently, with the acceleration of urbanization and the continuous growth of electricity demand, the scale and complexity of fire extinguishing devices are increasing day by day. Therefore, the safe operation of fire extinguishing devices is crucial to ensuring power supply. However, the safety management of traditional fire extinguishing devices is often based on static data and empirical formulas, which makes it difficult to comprehensively and accurately reflect the safety status of fire extinguishing devices under complex operating conditions. At the same time, the existing safety management of fire extinguishing devices is often carried out through regular manual inspections. Due to the scale and complexity of fire extinguishing devices, regular manual inspections cannot determine the real-time operating status of fire extinguishing devices, thus failing to detect safety hazards in a timely manner, assess the degree of danger of safety hazards, or guarantee the reliability of protective measures, which greatly reduces the effectiveness of safety monitoring and assessment of fire extinguishing devices. Therefore, in order to overcome the above-mentioned defects, the present invention provides a method for safety protection simulation and dynamic evaluation of a three-dimensional digital twin model of a fire extinguishing device.
