Description

Technical Field

[0001] This invention relates to the field of simulation testing equipment technology, specifically to a 3D model defect detection system based on AI recognition. Background Technology

[0002] In the fields of fire protection technology and industrial safety, research on combustion testing and fire simulation is crucial. This research not only helps to gain a deeper understanding of the causes, spread, and impacts of fires, but also provides important experimental evidence for the design, performance evaluation, and optimization of fire protection equipment. However, traditional fire simulation and detection systems have many limitations, such as inaccurate data acquisition, difficulty in real-time monitoring of the testing process, and insufficient safety protection measures. These problems greatly limit the effectiveness and safety of combustion testing.

[0003] With the rapid development of artificial intelligence (AI) technology, its applications in image recognition, data processing, and automatic control are becoming increasingly widespread, providing new possibilities for the innovation of fire simulation and detection systems. AI-based intelligent detection systems can achieve real-time monitoring, accurate identification, and rapid response at fire scenes, thereby significantly improving the efficiency of fire early warning and emergency response. However, most current AI-based fire detection systems on the market focus on post-fire monitoring and analysis, paying less attention to fire prevention and control during combustion tests.

[0004] Furthermore, effectively collecting and analyzing key data such as flame characteristics, combustion products, and heat release from the fire source during combustion tests is crucial for evaluating the performance of fire-fighting equipment and optimizing fire prevention strategies. However, traditional data acquisition systems often suffer from limited data acquisition range, insufficient accuracy, and poor real-time performance, making it difficult to meet the high standards required for modern combustion tests.

[0005] Meanwhile, safety protection measures during combustion tests are also an important aspect that cannot be ignored. Traditional safety protection systems mostly focus on the physical isolation of the test site and the evacuation of personnel, while measures to prevent heat in the air, corrosion from chemicals, and ensure communication during the test are relatively weak, making it difficult to fully guarantee the safety of test personnel and equipment. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By integrating a flame analysis system, data acquisition system, fire source heat release acquisition system, and AI acquisition system, the system can monitor and record key data such as flame characteristics, temperature, humidity, and gas concentration during combustion tests in real time and accurately. This provides detailed and reliable data support for subsequent fire prevention strategy optimization and fire equipment performance evaluation.

Furthermore, through the central control system in the central control room, test personnel can remotely control the fire extinguishing system to quickly control and extinguish the fire source, effectively reducing fire damage and enhancing emergency response capabilities.

[0018] 2. Based on the specific requirements of the experimental tasks, different working conditions are designed in the laboratory, including the type and location of combustibles, and fire-fighting methods. For example, simulating an accidental combustion of a helicopter fuel tank, the fire is controlled by high-pressure fine water mist. A suitable ignition system is selected to meet the ignition requirements under different tasks. It can be remotely started through the central control system in the central control room via the switch and the central centralized control execution system. The laboratory is equipped with a safety protection system to ensure the safety of the site, equipment, and personnel during the experiment. It can also be remotely started through the central control system in the central control room via the switch and the central centralized control execution system. The flue gas analysis and treatment system provides the ventilation conditions required for the experiment and collects, analyzes, and processes the flue gas generated by combustion. The flame analysis system, data acquisition system, and fire source heat release system collect combustion data and fire-fighting efficiency data under various working conditions, including thermal field distribution, flue gas component flow rate, fire source heat release, flame characteristics, etc., and transmit the data to the central control system. The AI ​​acquisition system collects the situation during the experiment and transmits the data to the central control system. The central control system centralizes all experimental data and displays it in the external monitoring room, laboratory, conference room, etc., through network communication in the conference system.

[0019] 3. The sub-control module is remotely started via a sub-control unit. The internal motor of the drive wheel rotates the drive wheel, enabling horizontal movement of the chassis in multiple directions. During the chassis movement, the automatic gimbal guides the camera to move in multiple angles, collecting external image data and sending it to the sub-control module. The sub-control module plans the chassis movement path based on the external image data and adjusts the drive wheels at corresponding positions in real time to change the movement direction. During chassis movement, the internal motor of the unwinding device drives the rotating roller to unwind the connecting hose, coordinating with the movement of the moving parts. Once the moving parts have moved to the designated position outside the helicopter model, the first motor drives the first sprocket to rotate, and the transmission chain... Driven by the transmission, the second sprocket rotates the outer shell of the tank upwards to the designated position inside the fixed frame, allowing the nozzle to extend into the helicopter model. The electric telescopic rod extends and retracts, driving the cylinder to move along the inner cavity of the limiting tank. When the cylinder moves to the end of the limiting tank, the second motor drives one side gear set to rotate, and the other side gear set drives the rotating shaft to rotate inside the cylinder, causing the rotating shaft to rotate the rotating frame to the other side. The third motor drives the annular fixed seat to rotate inside the mounting frame, and the annular fixed seat drives the nozzle to rotate to the designated angle, so that the nozzle is aimed at the fire source. The pump pressurizes the water stored in the water tank and supplies it to the inside of the nozzle through the connecting hose, so that the nozzle can extinguish the fire source at the designated location.

[0020] In summary, this invention can simulate different types of fires caused by different factors inside a full-size helicopter, extract combustion data, verify the fire extinguishing effectiveness of different fire-fighting facilities, and test the fire extinguishing effects of fixed and mobile fire-fighting equipment respectively when a fire occurs on a helicopter, thereby optimizing the design scheme of fire-fighting equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The central control room is equipped with a central centralized control and acquisition system, a switch group, a central control system, and a safety announcement system. The central centralized control and acquisition system is connected to the central control system through the switch group. The safety announcement system is directly connected to the central control system. The central control system is connected to a data processing system and two switches, one of which is connected to a display system and a conference system located outside the central control room. The laboratory is equipped with a flame analysis system, a data acquisition system, a fire source heat release acquisition system, an AI acquisition system, an ignition system, a safety protection system, a smoke analysis and processing system, and a fire extinguishing system.

[0031] The flame analysis system, data acquisition system, and fire source heat release acquisition system are connected to the central control system via a data acquisition control box located outside the central control room. The flame analysis system observes the visible characteristics of the flame, such as height, shape, and color, through a high-definition AI acquisition system. It collects flame spectral data using infrared and ultraviolet spectrometers. The controller preprocesses the data and inputs it into the flame data storage and analysis system, which analyzes the data to derive the basic characteristics of the flame. The data acquisition system uses a combination of various sensors to collect data on temperature, humidity, carbon dioxide, carbon monoxide, light, temperature, and smoke in real time. The fire source heat release acquisition system collects data on temperature and other parameters during the combustion of single and mixed combustibles in the test site. The data acquisition control box aggregates the data collected from the flame analysis system, data acquisition system, and fire source heat release acquisition system and stores it locally or uploads it to the cloud platform via the central control system to establish a relevant database. Staff can access the data from the central control system through the central control system.

The AI ​​acquisition system includes: a video acquisition module, a data preprocessing module, a feature extraction module, an intelligent analysis module, and a data storage and transmission module. The video acquisition module consists of multiple high-definition cameras distributed in different locations in the laboratory, including various corners, high places, and key areas where fire sources may occur, to ensure that the test site can be covered in all directions without blind spots. The cameras have the characteristics of high resolution, wide dynamic range, and low light, and can clearly capture video images under different lighting conditions. The data preprocessing module performs image enhancement processing on the acquired video frames, including brightness adjustment, contrast enhancement, and noise removal, to improve image clarity and quality, facilitating subsequent feature extraction and analysis. The feature extraction module uses deep learning algorithms to extract visual features of the flames, such as color, shape, texture, and motion trajectory, from the preprocessed video frames. For example, color features can be used to determine the temperature and intensity of the flames, while shape features can identify the type and direction of flame spread. Based on the extracted features, the intelligent analysis module uses machine learning and deep learning models to perform real-time analysis of the video data, determining whether a fire has occurred and its severity. Once fire signs are detected, an early warning signal is immediately issued, notifying the central control room and relevant personnel to take appropriate measures. The data storage and transmission module stores the acquired raw video data, preprocessed data, extracted feature data, and analysis results in a local database for subsequent querying, statistics, and analysis.

[0039] The working principle is as follows:

[0040] Step 1: Based on the specific requirements of the experimental task, design different working conditions in the laboratory, including the type and location of combustibles, fire-fighting methods, etc. For example, simulate the accidental combustion of a helicopter fuel tank, control the fire with high-pressure fine water mist, select a suitable ignition system to meet the ignition requirements under different tasks, and achieve remote start-up through the central control system in the central control room via the switch and the central centralized control execution system. The laboratory is equipped with a safety protection system to ensure the safety of the site, equipment and personnel during the experiment. The flue gas analysis and processing system is used to provide the ventilation conditions required for the experiment and collect, analyze and process the flue gas generated by combustion. The flame analysis system, data acquisition system and fire source heat release acquisition system collect combustion data and fire-fighting efficiency data under various working conditions, including thermal field distribution, flue gas component flow rate, fire source heat release, flame characteristics and other data, and transmit the data to the central control system. The AI ​​acquisition system collects the situation during the experiment and transmits the data to the central control system. The central control system centralizes all experimental data information and displays it in the external monitoring room, laboratory, conference room, etc. through network communication in the conference system.

[0041] Step 2: The ignition system ignites the helicopter model 5 inside the helicopter model 5 according to the fire requirements, and collects the combustion data of the helicopter model 5. After the combustion is completed, the central control system remotely starts the sub-control unit 4 through the switch and the central centralized control execution system. The pre-set system inside the sub-control unit 4 controls the high-pressure pump station 9 and the filter equipment 10 to start. The high-pressure pump station 9 supplies water to the fixed nozzle 6 and the suspended nozzle pipe 8 through the corresponding pipeline, so that the fixed nozzle 6 and the suspended nozzle pipe 8 respectively perform fire extinguishing and cooling operations on the side wall and top of the helicopter model 5. The wastewater after cooling and fire extinguishing flows into the filter equipment 10 through the drain outlet of the pre-embedded water tank shell 1. The filter equipment 10 filters the wastewater and discharges it into the high-pressure pump station 9 for storage and recycling.

[0042] Step 3: The sub-control unit 4 remotely starts the sub-control module 33. The pre-set system inside the sub-control module 33 controls the drive wheels 32, the automatic gimbal 36, and the guide camera 37 to start. The motor inside the drive wheels 32 drives the drive wheels to rotate, realizing the horizontal movement of the chassis 31 in multiple directions. During the movement of the chassis 31, the automatic gimbal 36 drives the guide camera 37 to move in multiple angle directions, so that the guide camera 37 collects external image data and sends it to the sub-control module 33. The sub-control module 33 plans the movement path of the chassis 31 according to the external image data and adjusts the drive wheels 32 at the corresponding positions in real time to change the movement direction. During the movement of the chassis 31, the pre-set program inside the sub-control unit 4 controls the unwinding device 23 to start. The motor inside the unwinding device 23 drives the roller to rotate to unwind the connecting hose 24 in coordination with the movement of the moving part 3. After the moving part 3 moves to the designated position outside the helicopter model 5, the pre-set program inside the sub-control module 33 controls the first motor 38, the electric telescopic rod 320, the second motor 317, and the third motor 324 to start. A motor 38 drives the first sprocket 39 to rotate, which, under the transmission of the transmission chain 312, drives the second sprocket 311 to rotate the outer shell 310 of the tank upward to the designated position inside the fixed frame 34, allowing the nozzle 325 to extend into the helicopter model 5. The electric telescopic rod 320 extends and retracts, driving the cylinder 314 to move along the inner cavity of the limiting groove 313. When the cylinder 314 moves to the end position of the limiting groove 313, the second motor 317 drives one side gear set 318 to rotate, and the other side gear set 318 drives the rotating shaft 315 to rotate on the cylinder 310. 14 rotates inward, causing the rotating shaft 315 to drive the rotating frame 319 to flip to the other side position. The third motor 324 drives the annular fixed seat 323 to rotate inside the mounting frame 322, and causes the annular fixed seat 323 to drive the nozzle 325 to rotate to the specified angle, so that the nozzle 325 is aligned with the fire source. The internal preset program of the sub-control unit 4 controls the pump body 22 to start. The pump body 22 pressurizes the water stored in the water tank 21 and supplies it to the nozzle 325 through the connecting hose 24, so that the nozzle 325 can perform fire extinguishing operations on the fire source at the specified location.
