Description

Technical Field

[0001] The present invention relates to the technical field of simulation test devices, and particularly to a 3D model defect detection system based on AI recognition. Background Art

[0002] In the fields of fire technology and industrial safety, the research on combustion tests and fire simulations is of crucial importance. These studies not only help to deeply understand the causes, spread processes and impacts of fires, but also provide important experimental bases for the design, performance evaluation and optimization of fire-fighting equipment. However, traditional fire simulation and detection systems have many limitations, such as inaccurate data collection, difficult real-time monitoring of the test process, insufficient safety protection measures, etc. These problems greatly limit the effectiveness and safety of combustion tests.

[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. The intelligent detection system based on AI recognition can achieve real-time monitoring, accurate recognition and rapid response to the fire scene, thus significantly improving the efficiency of fire early warning and emergency response. However, most of the current fire detection systems based on AI recognition on the market focus on the ex post monitoring and analysis of fires that have already occurred, and pay less attention to the fire prevention and control during the combustion test process.

[0004] In addition, during the combustion test process, how to effectively collect and analyze key data such as flame characteristics, combustion products and heat release of the fire source is of great significance for evaluating the performance of fire-fighting equipment and optimizing fire prevention and control strategies. However, traditional data collection systems often have problems such as limited data collection range, insufficient accuracy and poor real-time performance, and are difficult to meet the high standards of modern combustion tests.

[0005] At the same time, the safety protection measures during the combustion test process are also an important aspect that cannot be ignored. Most traditional safety protection systems focus on the physical isolation of the test site and the evacuation of personnel, while the measures in aspects such as blocking the heat in the air, the erosion of chemical substances and ensuring communication during the test process are relatively weak, and it is difficult to comprehensively ensure the safety of test personnel and equipment. Summary of the Invention

During the movement of the chassis, the automatic pan-tilt drives the guiding camera to move in multiple angular directions, enabling the guiding camera to collect external image data and send it to the inside of the sub-control module.

The electric telescopic rod extends and retracts to drive the cylinder body to move along the inner cavity of the limit groove. When the cylinder body moves to the end position of the limit groove, the second motor drives one side of the gear set to rotate, and the other side of the gear set drives the rotating shaft to rotate inside the cylinder body, and the rotating shaft drives the rotating frame to flip to the other direction position. The third motor drives the annular fixing seat to rotate inside the mounting frame, and the annular fixing seat drives the nozzle to rotate to the specified angle, so that the nozzle is aligned with the fire source position. The pump body pressurizes the water stored inside the water tank and supplies it to the inside of the nozzle through the connecting hose, enabling the nozzle to extinguish the fire at the specified position.

[0019] In summary, the present invention can simulate different types of fires caused by different incentives inside a full-size helicopter, extract combustion data, and can verify the fire extinguishing efficiency of different fire-fighting facilities. And it can simulate the situation when a helicopter catches fire, and test the fire extinguishing effects of fixed fire-fighting equipment and movable fire-fighting equipment respectively, so as to optimize the design scheme of fire-fighting equipment.

[0032] The working principle is as follows: Step 1: According to the specific requirements of the test task, different working conditions are designed in the laboratory, including the type of combustibles, the location of combustibles, fire-fighting means, 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 task requirements. It can be remotely started through the central control system in the central control room on the switch and the central centralized control execution system. A safety protection system is equipped in the laboratory to ensure the safety of the site, equipment and personnel during the test. It can be remotely started through the central control system in the central control room on the switch and the central centralized control execution system. The flue gas analysis and treatment system is used to provide the ventilation conditions required for the test and collect, analyze and process the flue gas generated by combustion. The flame analysis system, data acquisition system and heat release acquisition system of the fire source collect the combustion data and fire-fighting efficiency data under various working conditions, including data such as the thermal field distribution, the flow rate of flue gas components, the heat release of the fire source, and the flame characteristics, 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 centrally processes all data information of the test and displays it in the external monitoring room, laboratory, conference room, etc. through the network communication method in the conference system; Step 2: The ignition system ignites inside the helicopter model 5 according to the fire situation requirements to simulate the occurrence of a fire, and collects the combustion data of the helicopter model 5. After the combustion is completed, the central control system remotely starts the sub-control machine 4 on the switch and the central centralized control execution system. The pre-set system inside the sub-control machine 4 controls the start of the high-pressure pump station 9 and the filtering equipment 10. The high-pressure pump station 9 supplies water to the inside of the fixed nozzle 6 and the suspended nozzle pipe 8 through the corresponding pipelines, so that the fixed nozzle 6 and the suspended nozzle pipe 8 respectively perform fire extinguishing and cooling operations on the side wall and the top of the helicopter model 5.

The sub-control module 33 internally pre-sets the system to control the start of the driving wheel 32, the automatic pan-tilt 36, and the guiding camera 37. The motor inside the driving wheel 32 drives the driving wheel to rotate to achieve the horizontal movement of the chassis 31 in multiple directions. During the movement of the chassis 31, the automatic pan-tilt 36 drives the guiding camera 37 to move in multiple angular directions, so that the guiding camera 37 collects external image data and sends it to the inside of 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 driving wheel 32 at the corresponding position in real time to change the moving direction. During the movement of the chassis 31, the pre-set program inside the sub-control machine 4 controls the start of the unwinding device 23. The motor inside the unwinding device 23 drives the roller to rotate to unwind the connecting hose 24 to cooperate with the movement of the moving part 3. After the moving part 3 moves to the specified position outside the helicopter model 5, the pre-set program inside the sub-control module 33 controls the start of the first motor 38, the electric telescopic rod 320, the second motor 317, and the third motor 324. The first motor 38 drives the first sprocket 39 to rotate, and under the drive of the transmission chain 312, drives the second sprocket 311 to drive the tank housing 310 to turn upwards to the specified position inside the fixed frame 34, so that the nozzle 325 can extend into the helicopter model 5. The electric telescopic rod 320 extends and retracts to drive the cylinder body 314 to move along the inner cavity of the limit groove body 313. When the cylinder body 314 moves to the end position of the limit groove body 313, the second motor 317 drives the gear set 318 on one side to rotate, and the gear set 318 on the other side drives the rotating shaft 315 to rotate inside the cylinder body 314, and the rotating shaft 315 drives the rotating frame 319 to turn to the other side position. The third motor 324 drives the annular fixing seat 323 to rotate inside the mounting frame 322, and the annular fixing seat 323 drives the nozzle 325 to rotate to the specified angle so that the nozzle 325 is aligned with the fire source position. The pre-set program inside the sub-control machine 4 controls the start of the pump body 22. The pump body 22 pressurizes the water source stored inside the water tank 21 and supplies it to the inside of the nozzle 325 through the connecting hose 24, so that the nozzle 325 extinguishes the fire at the specified position.
