Description

Technical Field

[0001] This invention relates to the field of aviation fire and rescue equipment, specifically to an airport fire truck simulator. Background Technology

[0002] Airport fire trucks are specialized emergency rescue equipment developed within the civil aviation safety system specifically for aircraft fire suppression. Due to the rapid spread, intense heat radiation, and numerous chemical hazards associated with aircraft fires, the tactical configuration and operational procedures of civil aviation airport firefighting equipment require significant specialization. Based on this characteristic, an airport fire truck operation simulation system was developed. By constructing a 3D visualization training platform, it digitally replicates the entire process of aircraft fire suppression. Drivers can immerse themselves in the experience through a multi-channel interactive system, learning key operational aspects such as high-speed fire truck maneuverability and foam spray tactical applications, as well as corresponding response measures, thereby improving their practical skills. Therefore, the fire truck simulator is an efficient and ideal teaching and training device.

[0003] Currently, airport fire truck simulators primarily employ a single-person training mode, lacking real-time guidance and collaborative operation capabilities, thus limiting training efficiency and the degree of realism in simulated combat situations. Most simulators use a PC + USB interface + software simulation architecture, with signal transmission relying on the USB protocol's polling mechanism, which cannot support real-time synchronization for concurrent operation of multiple devices. While the PLC controller handles signal processing, data is transmitted serially between subsystems via digital I / O interfaces and data acquisition systems, resulting in accumulated latency and hindering real-time collaboration. Airport firefighting operations are highly complex, requiring operators to precisely control vehicles and firefighting equipment and respond quickly to dynamic fire situations. Traditional single-person simulators struggle to meet the needs for instructor intervention and team collaborative training. To address the shortcomings of single-person training, this invention designs a two-person assisted fire truck driving training simulator. Through a distributed simulation architecture, dynamic operation permission allocation, and low-latency data synchronization technology, it leverages the advantages of the CAN bus—its short frame structure, anti-interference capabilities, and long communication distance—to achieve collaborative training between instructors and trainees. The architecture of this invention separates critical operational signals from control commands through bus separation at the hardware layer, avoiding signal conflicts in software protocols. The system supports real-time operation demonstrations, error correction, and multimodal interaction, and incorporates evaluation to optimize training effectiveness. This improvement aligns with the trend towards intelligent and collaborative aviation firefighting training, significantly enhancing emergency response capabilities and training efficiency, and possesses significant engineering application value.

[0004] Airport fire trucks need to arrive at the scene as quickly as possible to control the fire, emphasizing high precision and timeliness of operation, requiring real-time coordination between the driver and commander. In civilian firefighting scenarios, single-person operation or simple coordination can handle most situations. However, civil aviation airport fire fighting requires simultaneously completing complex tasks such as high-speed positioning, precise fire monitor spraying, and dynamic tactical adjustments. Two-person coordination can improve trainees' emergency response capabilities through real-time instructor guidance. This is the core consideration in the design of this patent for civil aviation scenarios. Summary of the Invention

[0005] In view of this, the present invention discloses an airport fire truck simulator, the technical structure of which is as follows: the simulator includes a driver's cabin, an instructor control system, a computer simulation system, a visual system, and an audio system. It adopts a modular design, integrates 1:1 original parts of a real vehicle, and realizes real-time synchronization and real-time data interaction of signals from multiple subsystems with the main controller through a CAN bus controller. The control signals of the driving control system and the fire equipment control panel are connected to the visual host via data lines, driving the vehicle dynamics model, airport environment simulation, and aircraft fire and fire extinguishing interaction system in real time, generating dynamic three-dimensional visual and sound feedback. The instructor control console can monitor the trainee's operation in real time, dynamically adjust the training scene, and synchronously display the fire extinguishing effect through the visual host. It supports two-person collaborative training, multi-mode switching, and complex scene simulation, and has excellent application and promotion prospects in special fire extinguishing scenarios at airports.

[0006] To achieve the above technical effects, the following technical solution is adopted:

[0007] An airport fire truck simulator includes a driver's cabin, a driving control system, a CAN bus controller, a main controller, an instructor control system, a simulation training system, an instructor host, an instructor console, a visual system, a student display screen, a visual host, and a computer simulation system.

[0008] The computer simulation system includes a real-time vehicle dynamics system, an airport environment simulation system, and an aircraft fire and fire suppression interactive system.

[0009] The control signals of the driving control system are connected to the CAN bus controller through both the device bus and the control bus; the control signals of the driving control system are connected to the visual host through the main controller; the signal output of the instructor control system is controlled by the main controller; the signal output of the CAN bus controller is connected to the main controller, which is responsible for signal parsing and transmitting relevant data to the visual host, the instructor host and the computer simulation system. The main controller transmits and exchanges data with each subsystem at any time.

[0010] Furthermore, the cockpit body includes a cockpit shell, a student seat, an instructor seat, a student display screen, an instructor control console, and an engine start switch.

[0011] Furthermore, the driving control system includes a steering wheel system, a fire equipment control panel, an accelerator / brake pedal, a driving instrument panel, a gear control panel, and a parking brake lever; the steering wheel system includes a steering wheel, a steering shaft, and a direct-drive servo system.

[0012] Furthermore, the fire equipment control panel includes a fire information display screen, fire function buttons, and main and auxiliary water cannon control levers; the main and auxiliary water cannon control levers include a control handle positioning indicator light, a fire cannon outlet valve switch, a roof-mounted water cannon nozzle adjustment switch, a roof-mounted water cannon continuous water output switch.

[0013] Furthermore, the output data of the instructor control system is transmitted to the instructor host, which in turn transmits signals to the main controller. The main controller controls the display screen of the student display screen through the visual host and the visual system, and controls the action of the vehicle's real-time dynamics system.

[0014] Furthermore, the output data of the vehicle real-time dynamics system, airport environment simulation system, and aircraft fire and extinguishing interactive system are transmitted to the visual host in the visual system. The visual host generates a computer visual image and sends it to the student display screen for display. The audio system output is transmitted to the speakers to play simulated audio.

[0015] Furthermore, the output data of the simulation training system is transmitted to the instructor host, which generates a training simulation scenario and sends it to the instructor console for display. The output data of the simulation scenario is then transmitted to the main controller, and the signal output of the main controller is transmitted to the student display screen.

[0016] Furthermore, each system of the simulator adopts an independent modular design, and all components are made from 1:1 original parts from real vehicles.

[0017] This invention is a highly realistic training device developed for airport fire and rescue personnel. Through virtual reality technology and a simulation platform, it provides fire and rescue personnel with a realistic, safe, and efficient training environment. Based on real airport firefighting operations and incorporating typical emergency scenarios, this invention comprehensively simulates the driving operation of airport fire trucks, the execution of firefighting tactics, and on-site emergency response. This helps trainees master various key skills and improve their practical response capabilities without actually operating real vehicles. Instructors can select different scenarios and tasks from the simulation training system. The system receives status signals via a CAN bus controller and outputs the simulated training scenario to the trainees' displays. Data such as fire truck arrival time, aircraft fire development and control time, fire truck location trajectory, and firefighting operation process are all uploaded to the instructor's host in real time via the CAN bus. The instructor's console not only monitors and guides trainees in real time but also generates a trainee evaluation report after training to assess driving skills, firefighting efficiency, and tactical execution.

[0018] During driving training, the simulation system recreates an airport fire truck garage scene in the visual environment. When the instructor presses the start button on the engine start switch, the switch signal is collected by the CAN bus controller via the fire control subsystem and sent to the visual host via the device bus. The operation signals of the steering wheel, accelerator, brake pedal, and parking brake lever are all sent to the CAN bus controller via USB interface or CAN bus. All control mechanisms use original vehicle parts and have an automatic return function, ensuring realistic force feedback and mechanical damping characteristics. The signal output of the CAN bus controller is input to the visual host in real time through the main controller. The vehicle real-time dynamics system accurately calculates the dynamic state of the fire truck, such as speed, position, and acceleration, based on the collected road spectrum information, terrain, and virtual airport scene data. The airport environment simulation system and the aircraft fire and extinguishing interactive system are displayed on the trainee's screen through the visual system after fusion correction by a three-channel or single-channel 3D image system. The audio subsystem reproduces the sound effects of engine roar, road bumps, and fire extinguishing agent spray through multi-channel surround stereo high-fidelity speakers, providing realistic auditory positioning and immersion.

[0019] In the firefighting operation phase, the fire control system primarily achieves firefighting through the operation of fire-fighting equipment and buttons. This includes fire control buttons, a fire button panel, and main and auxiliary monitor control levers. The water cannon control lever is operated remotely from the driver's cab. The movement of the fire monitor in the visual environment is completely synchronized with the movement of the control lever. Trainees can individually control the main arm, auxiliary arm, spike arm, spike, and water cannon using the corresponding buttons on the fire handle. Each main and auxiliary fire monitor control lever supports four-way signal output (forward / backward, left / right), which is sent to the CAN bus controller via the CAN bus. The CAN bus controller communicates with the main controller and the visual environment host, primarily for transmitting fire commands. The CAN bus controller transmits fire commands generated by the trainee's operation of fire-fighting equipment such as the water cannon control lever and button panel to the main controller via network equipment. After receiving the commands, the visual environment host processes them logically and displays the fire status information in the scene on the fire front screen. Pressing the water pump start button and the desired fire monitor start button on the fire button panel, and adjusting the knobs on the fire button panel, controls the flow rate of the extinguishing agent output from the fire monitor nozzles. The fire and extinguishing agent spraying scenes are rendered by the visual system, and the sound system plays the sounds of high-pressure water jets and foam sprays in sync.

[0020] This system adopts a modular design: the operating equipment and the CAN bus controller belong to the "device bus" and "control bus" respectively, effectively isolating signal interference; the vehicle instrument group is modified from the original vehicle instrument and a driver board is added to fully reproduce the real instrument interface and status indication. The system also supports switching between multiple training modes, such as night training, severe weather (rain, snow, wind) simulation training, and multi-vehicle collaborative fire extinguishing drills; it has network-based connectivity, which can be linked with airport runway simulators and crew emergency response systems to realize cross-departmental comprehensive drills; it is also equipped with an emergency stop button and a fault self-diagnosis module, which can quickly interrupt the simulation and locate the source of the fault in case of abnormal situations, further ensuring the safety of trainees and equipment maintenance. The overall solution not only ensures high fidelity and safety of training, but also significantly reduces training costs and improves drill efficiency because the virtual environment can be reused and saves investment in real fire and large equipment.

[0021] The beneficial effects of the present invention are:

[0022] This invention utilizes a distributed simulation architecture, dynamic operation permission allocation, and low-latency data synchronization technology, leveraging the advantages of the CAN bus—its short frame structure, anti-interference capabilities, and long communication distance—to achieve collaborative training between instructors and trainees. The architecture design separates key operation signals from control commands at the hardware layer, avoiding signal conflicts in software protocols. The system supports real-time operation demonstrations, error correction, and multimodal interaction, and incorporates evaluation to optimize training effectiveness. This improvement aligns with the trend towards intelligent and collaborative aviation firefighting training, overcoming the limitations of most simulators that use a PC+USB interface+software simulation or PLC controller architecture, which cannot achieve collaborative training between instructors and trainees. Two-person collaboration enhances trainees' emergency response capabilities through real-time instructor guidance, a core consideration in this patent's design for civil aviation scenarios. It significantly improves emergency response capabilities and training efficiency, possessing significant engineering application value. Attached Figure Description

[0035] The computer simulation system 31 includes a real-time vehicle dynamics system 32, an airport environment simulation system 33, and an aircraft fire and fire suppression interactive system 34.

[0036] The control signals of the driving control system 8 are connected to the CAN bus controller 26 via both the device bus and the control bus; the control signals of the driving control system 8 are connected to the visual host 28 via the main controller; the signal output of the instructor control system 30 is controlled by the main controller 27; the signal output of the CAN bus controller 26 is connected to the main controller 27, which is responsible for signal parsing and transmitting relevant data to the visual host 28, the instructor host 29, and the computer simulation system 31. The main controller 27 transmits and exchanges data with each subsystem at any time.

[0037] like Figure 2 and Figure 3 As shown, the cockpit body 1 includes a cockpit shell 2, a student seat 3, an instructor seat 4, a student display screen 5, an instructor control console 6, and an engine start switch 7.

[0038] The driving control system 8 includes a steering wheel system 9, a fire equipment control panel 17, an accelerator / brake pedal 13, a driving instrument panel 14, a gear control panel 15, and a parking brake lever 16; the steering wheel system includes a steering wheel 10, a steering shaft 11, and a direct drive servo system 12.

[0039] The fire equipment control panel 17 includes a fire information display screen 18, fire function buttons 19, and main and auxiliary water cannon control levers 20; the main and auxiliary water cannon control levers 20 include a control handle positioning indicator light 21, a fire cannon outlet valve switch 22, a rooftop water cannon nozzle adjustment switch 23, a fire cannon nozzle adjustment switch 24, and a rooftop water cannon continuous water output switch 25.

[0040] The output data of the instructor control system 30 is transmitted to the instructor host 29, and the instructor host 29 transmits signals to the main controller 27. The main controller 27 controls the display screen of the student display screen 5 through the visual host 28 and the visual system 35, and controls the action of the vehicle real-time dynamics system 32.

[0041] The output data of the vehicle real-time dynamics system 32, the airport environment simulation system 33 and the aircraft fire and fire suppression interactive system 34 are transmitted to the visual host 28 in the visual system 35. The visual host 28 generates a computer visual image and sends it to the student display screen 5 for display. The audio system 37 outputs data to the speaker 38 to play simulated audio.

[0042] The output data of the simulation training system 36 is transmitted to the instructor host 29. After generating the training simulation scenario, the instructor host 29 sends it to the instructor console 6 for display and transmits the output data of the simulation scenario to the main controller 27. The signal output of the main controller 27 is transmitted to the student display screen 5 for display.

[0043] Each system of the simulator adopts an independent modular design, and all components are made from 1:1 original parts from real vehicles.

[0044] The vehicle real-time dynamics system 32 continuously calculates the key dynamic parameters of the fire truck and outputs the data in real-time to the visual system 35 in CAN bus format. The airport environment simulation system 33 is responsible for generating runway geometry, road surface friction, dynamic obstacles, and meteorological conditions, which are transmitted to the visual host 28 along with the fire spread model, heat flow distribution, and extinguishing agent spray feedback data provided by the aircraft fire and extinguishing interaction system 34. The visual host 28 integrates the above multi-source data, combines it with the pre-loaded 3D airport scene and fire dynamic model, renders a panoramic view, and outputs it to the trainee display screen to achieve a zero-latency, seamless immersive visual effect in the cockpit. At the same time, the audio system 37 decodes engine noise, wind shear noise, flame explosion sound, and extinguishing spray sound through multiple channels and plays it through the speakers 38 to create a stereo surround sound field. The simulation training system 36 collects comprehensive simulation data from vehicle dynamics, environmental simulation, and fire extinguishing modules and sends it to the instructor host 29. The instructor host 29 performs real-time visualization synthesis of multi-source data to generate a training simulation scenario that includes the trainee's perspective, fire situation, and tactical indicators, and presents it on the multi-screen display of the instructor control console 6. The instructor can switch camera perspectives, adjust the rate of fire evolution, or inject fault scenarios at any time to test the trainee's emergency response capabilities. After confirmation by the instructor, the instructor host 29 also sends control commands and synchronization signals of the training scenario to the main controller 27, which then distributes them to the trainee's display screen, instrument cluster, motion platform, and audio-visual equipment, ensuring that all systems remain synchronized throughout the training process and providing trainees with a highly realistic and safe and controllable comprehensive fire-fighting driving training environment.

[0045] The airport fire truck simulator is a comprehensive training platform integrating advanced technologies such as virtual reality, 3D modeling, motion simulation, and multi-channel projection. It is specifically designed to enhance the emergency response capabilities, firefighting skills, and collaborative combat abilities of airport firefighters. The system realistically recreates the structure of a fire truck cab at a 1:1 scale, integrating equipment such as a steering wheel, accelerator, brake, gear shift control, and fire monitor control handle. The visual system and multi-channel audio system work in tandem to provide trainees with an immersive training experience that combines visual, auditory, and dynamic elements.

[0046] During operation, the instructor selects the training subject on the control panel. After receiving the start command, the system initializes, loading parameters such as the fire truck dynamics model, fire development and control model, and sound model. It then sets the fire truck's orientation image and outputs it to the display screen. The simulator then starts and enters training mode. After system initialization, the set airport fire truck garage will be displayed on the visual screen. Once training begins, the trainee starts the fire truck in the driver's cab and operates the steering wheel, accelerator, brakes, and parking brake. The control data is collected in real-time via USB or CAN bus and fed back to the visual host via the CAN bus controller. Based on virtual terrain, road spectrum, and scene data, the simulation system calculates the vehicle's speed, position, and attitude changes, displaying the corresponding images on the visual screen. Simultaneously, the multi-channel audio system outputs dynamic sound effects such as vehicle engine sounds and bump sounds to enhance the immersive experience. During driving, the system collects operation data in real-time and performs dynamic calculations, displaying the current vehicle position and speed. The instrument panel and indicator lights synchronously display the vehicle's status, enhancing the realism of the operation.

[0047] Once the fire truck arrives at the simulated fire scene, the training enters the firefighting operation phase. Trainees operate the main and auxiliary water cannon handles and button panels on the fire control console to precisely control components such as the main arm, auxiliary arm, spikes, and water cannon. Control signals are transmitted via the CAN bus to the CAN bus controller, which then sends them to the visual host for logical processing. The system controls the movement and spray direction of the fire cannons in the scene according to input commands, rendering firefighting effects in real time, such as water jets, foam sprays, and flame suppression, and outputting high-fidelity spray sound effects. The fire front screen synchronously displays the cannon angle, boom status, and changes in fire intensity, helping trainees monitor tactical execution in real time. In addition, the fire button panel controls functions such as water pump start-up and flow rate adjustment, enabling trainees to master practical skills with various complex equipment. The visual system controls the dynamic changes of the fire scene in the visual display, simulating the process of spraying water or foam to extinguish the fire, while simultaneously outputting spray sound effects and flame explosion sounds. The fire model automatically adjusts the fire intensity based on the spray direction, intensity, and duration to simulate realistic firefighting effects. The system also supports training in complex scenarios such as severe weather conditions, different types of fire sources, and multi-vehicle coordination. It can generate evaluation reports based on set parameters, providing feedback on operational accuracy, reaction speed, and firefighting efficiency. Throughout the training process, the simulator supports two-person collaborative operation, allowing instructors to monitor trainees' actions in real time and provide guidance and evaluation as needed. The system also features data acquisition and analysis capabilities, recording trainees' operational data and generating evaluation reports to provide a basis for subsequent training and improvement.

[0048] Airport fire truck simulators not only highly replicate the entire process from fire emergency response to firefighting, providing multi-dimensional training content including driving, firefighting, and command, but also effectively solve problems such as expensive equipment, high safety risks, and limited training scenarios in traditional field training. They are a crucial technological means for building a smart civil aviation emergency response system and enhancing airport fire and rescue capabilities. This system integrates teaching, training, and assessment through virtual simulation and human-computer interaction, providing firefighters with a safe, efficient, low-cost, and repeatable modern training platform.

[0049] In summary, this invention discloses an airport fire truck simulator. Its technical structure includes a driver's cabin, an instructor control system, a computer simulation system, a visual system, and an audio system. It adopts a modular design, integrating 1:1 original components from a real vehicle. A CAN bus controller enables real-time synchronization and data interaction between multiple subsystems and the main controller. Control signals from the driving control system and fire equipment control panel are connected to the visual host via data lines, driving the vehicle dynamics model, airport environment simulation, and aircraft fire and firefighting interaction system in real time, generating dynamic three-dimensional visual and sound feedback. The instructor control console can monitor trainee operations in real time, dynamically adjust the training scenario, and synchronously display the firefighting effect through the visual host. It supports two-person collaborative training, multi-mode switching, and complex scenario simulation, demonstrating excellent application and promotion prospects in special airport firefighting scenarios.
