Abstract
Description
Technical Field
[0001] This invention relates to the field of fire detection and emergency response technology, specifically to a system and method for early detection and intelligent emergency response to fires in enclosed spaces based on digital twins. Background Technology
[0002] Due to their enclosed spaces, poor ventilation, and complex structures, enclosed spaces are prone to problems such as smoke accumulation, rapid temperature increases, and the spread of toxic gases after a fire breaks out. Furthermore, rescue efforts are difficult, and fires can easily result in significant casualties and property damage. Current fire prevention and control technologies for enclosed spaces mainly focus on two aspects: Fire detection technology: Existing technologies mostly use traditional equipment such as point-type smoke detectors, heat detectors, and infrared flame detectors, which rely on a single physical parameter (such as smoke concentration and ambient temperature) to trigger alarms. This type of technology has obvious limitations: the weak signals generated by fires in the very early stage (smoldering stage) are easily interfered with by the complex environment of a confined space, resulting in alarm delays, usually 3 to 5 minutes; it cannot accurately locate the fire source, and is easily affected by dust, water vapor, etc., resulting in false alarms, with a false alarm rate as high as 5% to 8%.
[0003] Emergency response technology: Existing emergency response relies heavily on manual operation or pre-set fixed procedures, such as manually activating fire extinguishing devices or shutting down ventilation systems after an alarm is triggered. This mode has problems such as delayed response, manual response time is usually ≥10 minutes, and fixed response plans. It is impossible to dynamically adjust strategies according to the stage of fire development, the distribution of people in the confined space, and the operating status of equipment, which can easily lead to secondary disasters caused by untimely response or inappropriate measures.
[0004] The aforementioned existing technologies have the following core defects: ① Low accuracy in very early detection, delayed alarms and high false alarm rate; ② Insufficient integration of virtual and real systems, the digital twin model cannot accurately map the development of the fire; ③ Low level of intelligence in emergency response, lacking a dynamic and adaptive decision-making mechanism; ④ The detection and response processes are separated, failing to form a closed-loop management system for the entire process.
[0005] Digital twin technology enables real-time interaction and collaboration between virtual and real data by constructing virtual mappings of physical entities. It has been widely used in fields such as smart manufacturing and urban management. However, in the field of fire prevention and control in enclosed spaces, existing applications still have shortcomings. Most technical solutions only achieve scene visualization and do not deeply integrate early fire detection data. The synchronization accuracy between virtual models and physical entities is low, with a synchronization error of ≥1m, which cannot support accurate emergency decision-making. It lacks a closed-loop mechanism for the entire process of "detection-analysis-decision-response", and the core value of digital twins has not been fully realized.
[0006] Chinese patent application number 2021114957278 provides a fire monitoring method and system based on artificial intelligence and digital twin technology. This technical solution uses a database of components such as fire scene values from a digital twin system and fire scene data collected by simulated experimental sensors to train an artificial intelligence model for fire situation judgment and monitoring. It is not directly applied to real fire prevention, especially fire detection and handling in confined spaces.
[0007] Therefore, there is an urgent need to build a closed-space fire detection and prevention system that integrates digital twin technology to achieve "very early and accurate detection, real-time synchronization between virtual and real systems, intelligent dynamic decision-making, and rapid closed-loop response," thereby improving the initiative and effectiveness of closed-space fire prevention and control. Summary of the Invention
[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a system and method for early detection and intelligent emergency response to fires in enclosed spaces based on digital twins.
[0009] In a first aspect, the present invention provides a fire detection and emergency response system, comprising a data support layer, a physical sensing layer, a digital twin layer, an intelligent decision-making layer, and an emergency response layer. The data support layer provides support for the storage and management of detection data. The physical sensing layer is used to acquire fire detection data and environmental and equipment status data within a confined space. The digital twin layer constructs a virtual mapping model of all elements of the confined space, realizing real-time synchronization, data fusion, and visualization of the physical entity and the virtual mapping model. The intelligent decision-making layer realizes early fire identification, risk assessment, and generates an emergency response plan based on the detection data and the status of the virtual mapping model. The emergency response layer executes the emergency response plan output by the intelligent decision-making layer.
[0010] Furthermore, the data support layer further includes a distributed database, a data security unit, and a data interface unit.
[0011] Furthermore, the physical sensing layer further includes an early detection unit, an environment and equipment status unit, and a data transmission unit. The early detection unit consists of a distributed pyroelectric ion sensor, a microelectromechanical system (MEMS) smoke sensor, and an infrared temperature measurement array. The pyroelectric ion sensor collects changes in ion concentration at a frequency ≥20Hz with an accuracy of ±0.1ppb. The MEMS smoke sensor collects the concentration of weak smoke particles with a detection limit ≤0.001mg / m³. The infrared temperature measurement array monitors the regional temperature distribution within a range of -40℃ to 300℃ with an accuracy of ±0.05℃. The environment and equipment status unit consists of a temperature and humidity sensor, an oxygen concentration sensor, a combustible gas detector, and an equipment status monitoring module. It collects environmental parameters of the enclosed space in real time. The environmental parameters include temperature, humidity, oxygen concentration, combustible gas concentration, and the operating status of ventilation equipment and electrical equipment. The operating status includes voltage, current, and start / stop status. The data transmission unit has a data transmission delay of ≤100ms and a reliability of ≥99.99%.
[0012] Furthermore, the digital twin layer further includes a twin model construction unit, a virtual-real synchronization engine, and a visualization display unit. The twin model construction unit constructs a detailed three-dimensional model including a closed space structure, equipment layout, and detection and handling equipment, with a model accuracy of ≤0.1m. The virtual-real synchronization engine receives data from the physical perception layer and performs preprocessing, including data cleaning and noise filtering. The visualization unit displays detection data, fire development status, and emergency response progress in real time.
[0013] Furthermore, the intelligent decision-making layer further includes an early detection unit, a risk assessment unit, and an intelligent decision-making engine. The early detection unit first extracts the ion concentration mutation rate, smoke particle growth rate, and temperature gradient, and then achieves feature fusion through an improved Transformer algorithm. Combined with the environmental baseline of the confined space, the detection threshold is dynamically adjusted. The environmental baseline is dynamically generated through self-learning from the initial 72 hours of data. The accuracy rate of early fire detection is ≥99.7%, and the false alarm rate is ≤0.08%. The risk assessment unit uses the analytic hierarchy process (AHP) to assess the fire risk level and marks the risk areas with different colors in the digital twin model. The intelligent decision engine constructs a decision system that includes a rule base, a case library, and an AI prediction model. The rule base stores the basic handling rules required by fire protection regulations, the case library includes at least 500 similar cases of fire handling in enclosed spaces, and the AI prediction model predicts the development trend of fires based on the LSTM algorithm.
[0014] Furthermore, the emergency response layer 105 further includes an equipment linkage unit, a personnel evacuation guidance unit, and a response effect feedback unit, wherein the equipment linkage unit is linked with the fire-fighting equipment, ventilation system, and electrical equipment in the enclosed space, and the linkage response time is ≤1s; The personnel evacuation guidance unit pushes dynamic evacuation routes through emergency broadcasts, indicator lights, and personnel mobile APPs in the enclosed space. The dynamic evacuation routes are planned in real time based on a digital twin model. The response effect feedback unit collects detection data after emergency response in real time and feeds it back to the intelligent decision-making layer. If the response effect does not meet expectations, it triggers iterative optimization of the solution.
[0015] Secondly, the present invention provides a fire detection and emergency response method, comprising the following steps: Step 201: System initialization and baseline establishment. After the system starts, the physical perception layer collects the initial environmental data of the enclosed space, the digital twin layer builds a three-dimensional model based on the initial environmental data, and the intelligent decision-making layer generates the environmental baseline and normal operation threshold based on the initial environmental data. Step 202: Very early data acquisition and virtual-real synchronization: The physical sensing layer collects ion concentration, smoke concentration and temperature in real time, and transmits them to the digital twin layer after preprocessing to drive the virtual model to update dynamically and realize the visualization of fire characteristic parameters. Step 203: Fire identification and risk assessment. The intelligent decision-making layer extracts multi-dimensional features from the data collected by the physical perception layer and identifies very early fire signals through a fusion algorithm. If an anomaly is detected, a risk assessment is initiated, and the risk level is determined by combining personnel and equipment data. Step 204: Intelligent decision-making and plan execution. The decision engine combines risk level and fire development prediction to generate dynamic response plans. The emergency response layer automatically links equipment for execution and provides real-time feedback on the response results. Step 205: Determine whether the fire is under control. If the fire is effectively controlled, proceed to step 206; otherwise, return to step 204 to regenerate and execute the response plan. Step 206: Closed-loop optimization and recovery. If the treatment effect meets the standards, the system records the treatment process and restores the system to the monitoring state.
[0016] Thirdly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the fire detection and emergency response method as described in the second aspect.
[0017] Fourthly, the present invention provides a fire detection and emergency response device, comprising: One or more processors; Memory; and One or more computer programs, wherein the one or more computer programs are stored in the memory and configured to be executed by the one or more processors, wherein the processors execute the computer programs to implement the steps of the fire detection and emergency response method as described in the second aspect.
