Description
Technical Field
[0001] This invention relates to the field of simulation demonstration education technology, specifically to a TEDS hands-on simulation system and its data processing method. Background Technology
[0002] Currently, there is a lack of professional training methods and means for TEDS dynamic inspection operators. Unlike other EMU mechanic positions, where ground mechanics and on-board mechanics have well-established training systems for new hires and transfers, TEDS (Dynamic Image Detection System for EMU Operation Faults) dynamic inspection operators locate faults through EMU image analysis, which differs from the actual equipment. While on-site training can enhance TEDS analysts' grasp of basic EMU knowledge, it doesn't practically help or improve their TEDS inspection skills, failing to meet actual production needs.
[0003] TEDS inspection work involves analyzing images of EMU trains to identify and address potential faults within a limited timeframe. Furthermore, TEDS dynamic inspection personnel analyze all EMU train models that pass through detection stations across the entire railway network, placing extremely high demands on the personnel's knowledge of EMU trains, their professional skills, and their work efficiency.
[0004] With the widespread adoption of TEDS, the training of analysts with strong professional skills and advanced technical expertise has become increasingly urgent. Previous learning methods cannot be quickly adapted to TEDS operational systems, leading to misjudgments and omissions by analysts, posing a threat to the safety of high-speed train operations. Summary of the Invention

By simulating and restoring the TEDS system's operational baseline, real faults are transferred to the fault database, allowing users to access, learn, and simulate operations at any time, thus improving learning efficiency. The screen is consistent with the real operation screen, solving the problem that trainees could not get started with actual operation in the past.
[0006] This invention is achieved through the following technical solution: In a first aspect, the first embodiment of the present invention provides a TEDS implementation simulation system, comprising: a human-computer interaction module, a base map creation module, a fault database module, and a simulation module; The human-computer interaction module is used to obtain login information input by the user; The base map creation module obtains the original image of the TEDS EMU from the TEDS operation platform and generates the TEDS practical simulation system EMU operation base map based on the original image of the TEDS EMU. The fault database module is used to acquire TEDS predicted fault images, crop fault images from TEDS predicted fault images, match fault images with the TEDS actual simulation system EMU operation base map to obtain processed images, save the processed images to the fault database, and number the fault data. The simulation module is used to obtain the vehicle model and simulation mode selected by the user, and retrieve the fault data corresponding to the vehicle model and simulation mode from the TEDS fault database module to generate a simulated TEDS inspection operation scenario.
[0007] The base map production module includes an image stitching unit, which is used to stitch together the original images of the TEDS EMU into an image of the entire EMU carriage and complete the image layout of the 7 channels to restore the base map of the actual TEDS analysis operation.
[0008] Furthermore, the base map production module also includes a first data storage unit, which is used to acquire the coordinates and dimensions of the stitched image of the entire EMU carriage and store it in the fault database.
[0009] Furthermore, the fault database module includes an image preprocessing unit, which is used to preprocess the TEDS-predicted fault images and classify and number them according to the train type, component, and image quality.
[0010] Furthermore, the fault database module also includes an image processing unit, which is used to crop fault images from TEDS-predicted fault images and stitch the fault images onto the corresponding vehicle model base image.
[0011] Furthermore, the fault database module also includes a second data storage unit, which is used to obtain the location of the fault diagram, store the coordinates and dimensions of the fault diagram in the fault database, and number them according to the train type and channel.

[0014] Furthermore, the simulation system includes a training unit, which is used to obtain the vehicle model and training method selected by the user, and retrieve the fault data corresponding to the vehicle model and training from the fault database to generate a simulated TEDS inspection operation scenario.
[0015] Secondly, another embodiment of the present invention provides a data processing method for a TEDS implementation simulation system, comprising: Get the login information entered by the user; Determine the user's identity information based on the user's login information; If the user is an administrator, the system enters the production mode, retrieves the original images of the TEDS EMU from the TEDS operation platform, generates the TEDS practical simulation system EMU operation base map based on the original images of the TEDS EMU, obtains TEDS predicted fault images, crops fault images from the TEDS predicted fault images, matches the fault images with the TEDS practical simulation system EMU operation base map to obtain the processed images, saves the processed images to the fault database, and assigns fault data numbers.

[0018] To more clearly illustrate the technical solutions of the exemplary embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below. It should be understood that the following drawings only show some embodiments of the present invention and should not be considered as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort. In the drawings: Figure 1 A schematic diagram of the structure of a TEDS implementation simulation system provided for the first embodiment of the present invention; Figure 2 A flowchart of a data processing method for a TEDS implementation simulation system provided in another embodiment of the present invention. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.
[0020] like Figure 1 As shown, the first embodiment of the present invention provides a TEDS implementation simulation system, including: a human-computer interaction module, a base map creation module, a fault database module, and a simulation module; The human-computer interaction module is used to obtain login information input by the user; The base map creation module obtains the original image of the TEDS EMU from the TEDS operation platform and generates the TEDS practical simulation system EMU operation base map based on the original image of the TEDS EMU. The fault database module is used to acquire TEDS predicted fault images, crop fault images from TEDS predicted fault images, match fault images with the TEDS actual simulation system EMU operation base map to obtain processed images, save the processed images to the fault database, and number the fault data. The simulation module is used to obtain the vehicle model and simulation mode selected by the user, and retrieve the fault data corresponding to the vehicle model and simulation mode from the TEDS fault database module to generate a simulated TEDS inspection operation scenario.
[0021] When using the TEDS practical simulation system provided in this embodiment, users log in to the system by entering login information through the human-computer interaction module. Login information includes username and password, and the user selects to enter either the TEDS system or the CV system. The user's identity can be determined based on the login information; the user's identity includes trainee, administrator, and trainer. Administrators can create base maps and a fault database. Administrators create base maps using the base map creation module and manage the database using the fault database module. Trainees take exams and practice using the simulation module. Trainers conduct specialized training using the simulation module.
[0022] This embodiment provides a TEDS (Traffic Emergency Response System) simulation system that integrates images from TEDS detection stations for over 10 types of high-speed trains, including CRH1A, CRH2A, CRH380A, CRH3C, CRH5A, CRH380D, Fuxing 400BF, and Fuxing 400AF. The system integrates images from detection stations for over 10 mainstream high-speed trains, covering train models with different technical platforms and design specifications. This feature overcomes the previous problem of isolated data in single-train model TEDS systems, allowing managers to process image data from multiple train models within a single simulation system without switching between multiple systems. This significantly improves training and verification for different train model inspection operations and is suitable for TEDS simulation scenarios with multiple managed lines and complex train model assignments.
[0023] The base map creation module includes an image stitching unit, which stitches together original images of the TEDS EMU to create an image of the entire EMU carriage and arranges the images across seven channels, reconstructing the base map for the actual TEDS analysis operation. The module also includes a first data storage unit, which acquires the coordinates and dimensions of the stitched image of the entire EMU carriage and stores them in the fault database. Compared to fragmented images, the stitched image of the entire carriage allows analysts to intuitively see the complete layout and relationships of each component, avoiding the omission of interconnected faults due to the limitations of a single image, such as cross-regional faults like loose pipelines at carriage connections. Furthermore, the standardized arrangement of the seven channels corresponds to different key inspection areas of the EMU, enabling comprehensive coverage of key areas such as the running gear, braking components, and both sides of the car body, reducing blind spots in inspection. Management personnel create base maps for each channel of the TEDS system using the base map creation module. The image stitching unit then stitches together fragmented original images of the TEDS EMU into a complete EMU carriage. The layout of the images for the seven channels is completed according to the TEDS China Academy of Railway Sciences system, creating a 1:1 replica of the actual TEDS analysis interface. This allows analysts to perform simulated analyses in the simulation system with completely consistent operational logic and image presentation with the real work scenario, reducing the adaptation costs for cross-scenario operations. Furthermore, the system serves as a training platform for TEDS analysts, enabling newcomers to familiarize themselves with image viewing and fault identification processes for different train models and channels in a simulation environment. This avoids operational errors caused by unfamiliarity with the real system, providing a high-fidelity operating environment for training. The first data storage unit stores the X-axis, Y-axis, width (W), and height (H) of the stitched images and records the specific data in a MySQL fault database.
[0024] A nationwide database of typical TEDS (Train Headquarters Predicted Surgery) faults has been compiled. Over 15,000 TEDS fault prediction images were initially collected and input into the fault database module, which is regularly updated to ensure comprehensive data. The module includes an image preprocessing unit to preprocess TEDS fault prediction images and categorize them by train type, component, and image quality. An image processing unit selects suitable images from the massive dataset, crops fault images, and stitches them onto the corresponding train type base image. A secondary data storage unit retrieves the fault image location, stores its coordinates and dimensions in the database, and numbers it by train type and aisle. Administrators can view the fault image location through this unit, recording X-axis, Y-axis, width (W), and height (H) data in a MySQL fault database, also numbered by train type and aisle. The completed fault database facilitates access for later examinations, exercises, and training. To prevent analysts from rote memorization of faults, an image processing unit can stitch fault images onto the same location on other vehicles, assigning faults vehicle-specific and channel-specific numbers before writing them into a fault database. The same fault can be randomly combined with other faults to appear in different locations, avoiding repetition. These faults can be randomly selected during practice exams, and multiple sets of exam questions can be created using the same fault to increase the difficulty of practice.
[0025] The simulation module includes a simulated examination unit. This unit acquires the user-selected vehicle model and examination method, retrieves corresponding fault data from the fault database to generate a simulated TEDS inspection scenario, and obtains information on fault images found by the user within the simulated TEDS inspection scenario for automatic scoring. In the examination mode, the examiner pre-sets the vehicle model and faults. All candidates can directly select the simulated examination unit to take the exam simultaneously. The exam paper consists of the pre-set vehicle model and fault questions. A green box appears when a trainee clicks on the center of a fault image; a red box appears if no fault is found after the time limit. The system then counts the fault images found by the trainee and scores them. This allows management to evaluate the effectiveness of training for trainees, on-the-job personnel, and at each stage of training.
[0026] The simulation system includes a simulation practice unit. This unit acquires the user-selected vehicle model and simulation practice method, retrieves fault data corresponding to the model and practice from the fault database to generate simulated TEDS inspection scenarios, and obtains information on fault images found by the user within these scenarios for automatic scoring. Simulation practice methods include a practice mode (random number of faults) and a quantitative practice mode (quantitative number of faults). The practice mode randomly sets faults, allowing analysts to independently select vehicle models for practice and self-testing. Both the number and type of faults are randomly determined by the system, enabling learners to learn independently based on their own abilities. This significantly improves efficiency compared to previous methods, reducing intermediate steps such as training plan applications. The quantitative practice mode is similar to the practice mode, but the number of faults is fixed at a set quantity, such as 10. This function allows learners to self-assess, identify weaknesses, and focus their learning accordingly.
[0027] The simulation system includes a training unit. This unit acquires the user-selected train model and training method, retrieves corresponding fault data from the fault database to generate simulated TEDS inspection scenarios. Trainers use the training unit to train participants, and the unit itself retrieves fault data from the fault database to generate simulated TEDS inspection scenarios. For example, images of high-speed trains passing through TEDS detection stations can be collected based on seasonal changes, such as trains covered in ice and snow in winter. This data can then be used to provide specialized training to personnel, enabling scenario-based training before winter arrives.
[0028] The first embodiment of this invention provides a TEDS practical simulation system. By simulating and recreating the TEDS system's operational baseline, it transplants real faults into a fault database, allowing trainees to access and learn from the database at any time, thus improving learning efficiency and effectiveness. Trainers can switch between different train sets for explanation as needed, with the visuals consistent with real-world operations. This solves the previous problem of trainees being unable to perform hands-on practice, improving training efficiency and avoiding the labor risks associated with overlapping on-site learning and operations. Using this system, the training cycle for TEDS dynamic inspectors has been reduced from 6 months to 3 months, and the fault detection rate has increased from 60% to approximately 93% after implementation.
[0029] like Figure 2 As shown, another embodiment of the present invention provides a data processing method for a TEDS implementation simulation system, comprising: Get the login information entered by the user; Determine the user's identity information based on the user's login information; If the user is an administrator, the system enters the production mode, retrieves the original images of the TEDS EMU from the TEDS operation platform, generates the TEDS practical simulation system EMU operation base map based on the original images of the TEDS EMU, obtains TEDS predicted fault images, crops fault images from the TEDS predicted fault images, matches the fault images with the TEDS practical simulation system EMU operation base map to obtain the processed images, saves the processed images to the fault database, and assigns fault data numbers. If the user is a student, the system enters student mode, obtains the vehicle model and simulation method selected by the student, and generates a simulated TEDS inspection operation scenario based on the selected vehicle model and simulation method, which includes exams and practice, by retrieving fault data corresponding to the vehicle model and simulation method from the fault database. If the user is a trainer, the system enters training mode, obtains the vehicle model and training method selected by the trainer, and retrieves the corresponding fault data from the fault database based on the selected vehicle model and training method to generate a simulated TEDS inspection operation scenario.
[0030] The present invention provides a data processing method for a TEDS practical simulation system. By simulating and restoring the TEDS system's operational baseline, the method transfers real faults to a fault database, allowing students to access and learn from the database at any time and perform simulated operations, thereby improving learning efficiency and effectiveness.
