Description

Technical Field

[0001] The present invention relates to the field of computer software technology, and in particular to a business quality assessment method based on a centralized scheduling system simulation platform. Background Art

[0002] Implementation of existing technology: 1. It mainly relies on traditional teaching and assessment and the master-apprentice system of "teaching, helping and guiding", focusing on theoretical explanations and lacking practical exercises. The training cycle is long and the efficiency is low.

[0003] 2. Single interlocking standard station simulation uses a standard station type to implement single interlocking simulation, which fails to cover all production and use software of vehicle maintenance personnel. The assessment and evaluation is mainly based on the subjective judgment of the evaluators, with many qualitative indicators and insufficient quantitative indicators. For example, the simulation of a single interlocking standard station requires the coordination of multiple people and multiple machines, and manual or semi-automatic assessment relies on the cooperation of vocational education personnel, and the physical and real-life assessment combining scheduling and signaling is not realized.

[0004] 3. The drills for single procedures are limited to single desktop drills, with few comprehensive practical drills, incomplete coverage of fault cases, and a lack of quantitative and objective indicators in the evaluation of drills.

[0005] Disadvantages of existing technology: 1. The effectiveness of training is heavily dependent on the ability and energy of vocational education specialists. During the training process for driving personnel, the emphasis is placed on knowledge indoctrination, while skills development is neglected. The same training approach is adopted for all trainees, regardless of position or level, focusing on theoretical explanations and lacking practical training in operational skills. Furthermore, the effectiveness of training is heavily dependent on the personal ability and energy of vocational education specialists. If time is tight and the workload is heavy, the training effect is often significantly reduced.

[0006] 2. The training and assessment process lacks a high degree of intelligence. With the widespread adoption of centralized dispatching systems, the automation level of station signaling equipment has gradually increased. However, employee training still relies on classroom instruction, a three-step model where teachers lecture, students listen, and then take exams. The entire process requires the full cooperation of vocational education staff, and there is a lack of methods and means to verify the effectiveness of training tasks, resulting in a lack of objectivity in the evaluation of employee professional quality.

[0007] 3. Training plans and assessment results lack scientific analysis. Currently, each station section independently formulates its own training plan according to the overall requirements of the railway bureau. Due to insufficient understanding of employees' weaknesses, the training plans are not very scientific. Moreover, due to the lack of statistical analysis, the assessment results of each station section cannot provide feedback to guide the optimization of the training plan. Summary of the Invention

[0008] In view of the above problems, the present invention is proposed to provide a business quality assessment method based on a centralized scheduling system simulation platform that overcomes the above problems or at least partially solves the above problems.

[0009] According to one aspect of the present invention, a method for evaluating service quality based on a centralized scheduling system simulation platform is provided, the method comprising: Signal infrastructure simulation, including: The signal infrastructure simulation equipment simulates actual line data as a basis, builds stations and bridges consistent with their actual locations in a virtual environment, and draws a line topology consistent with the actual station type; Simulate the dynamic operation of trains in the dispatching section and automatically generate train occupation, clearing and signal closure status in sequence; Simulating station code position change information and section code position change information lays the foundation for the construction of train operation, dispatching and vehicle operation simulation; Train operation simulation, simulates the train traction and braking model for development, and receives data from track circuits and signal machines in the signal basic simulation environment; Generate target distance speed continuous control curve in real time, and monitor train speed by using normal braking and emergency braking; Train operation simulation: When encountering a signal closure, red light band on the track circuit, or line blockage, the train stops before the closed signal or occupied track circuit; Automatically build scenes.

[0010] Optionally, the automatic scene construction specifically includes: Based on the statistical analysis of emergency drill assessments, the corresponding rules and regulations covered by each scenario are sorted out, and data and processing flow calculations are performed for the assessment scenarios.

[0012] Optionally, the station duty personnel assessment and evaluation system includes: a data service layer DL, a connection adaptation layer LL and a basic hardware layer HL; The architecture of the basic hardware layer is the foundation of the assessment and training platform. It is designed in detail according to the access layer, network layer and hardware layer to support the access requirements between various business systems, meet the environmental and performance requirements of business software operation, and support the scalability requirements of the training platform. The architecture of the connection adaptation layer is the core of the assessment and training platform. By studying the central bus structure used to adapt basic signal simulation, CTCS system simulation, and CTC simulation, real signal data is injected to reproduce all static trackside signal equipment on the line. Through the adaptation engine model of train simulation and train control equipment, all signals and train control equipment are organically integrated to drive the train on the virtual line. The architecture of the business data layer is the focus of the assessment and training platform. By implementing logical operations and data interfaces between the train control system, interlocking system and CTC, a business interface consistent with the real production environment is constructed for dispatchers and station attendants.

[0013] Optionally, all static trackside signal equipment on the line specifically includes: the position and status of track circuits, signal machines, switches, transponders, and phase zone equipment.

[0014] This invention provides a professional competency assessment method based on a centralized dispatching system simulation platform. This method includes: signal infrastructure simulation; train operation simulation, including development of a simulated train traction and braking model; and automatic scenario construction. This highly simulated centralized dispatching system training platform enables scenario-based, hands-on training and intelligent assessment for train personnel, addressing existing training and assessment issues such as insufficient intelligence, subjective evaluation, and low efficiency, thereby improving personnel's professional competency and emergency response capabilities.

DETAILED DESCRIPTION

[0018] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0019] The terms "comprises" and "comprising" and any variations thereof in the description, embodiments, claims and drawings of the present invention are intended to cover non-exclusive inclusions, for example, including a series of steps or units.

[0020] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1 like Figure 3 As shown, the system architecture design scheme of the present invention uses software modeling and actual field data injection to reconstruct outdoor signal equipment (turnouts, signal machines, track circuits), computer interlocking systems, section block systems, radio block centers, temporary speed limit servers, on-board systems, wireless train number verification systems, and wireless dispatch command transmission systems. It also simulates and builds a simulated dispatching centralized network, GSM-R network, signal safety data network, and basic signal simulation network, organically combining the CTC system, CTCS system, disaster prevention system, and other signal equipment to achieve logical authenticity, standard interfaces, and complete systems, meeting the needs of signal system and dispatch system integration. Therefore, this scheme simulates the CTC system, CTCS system, and other signal equipment as single products according to product technology, and uses standard interfaces for data exchange between various simulation software, thereby building a fully functional train personnel business quality assessment system based on an intelligent simulation training platform.

[0022] Simulate a driving organization scenario that is highly consistent with the on-site situation. By investigating the business correlations between various professions and trades on-site, studying the key operation control points of the logical relationship, and using workflow technology that can be streamlined and formatted for editing to organize scenarios and processes, study the implementation method that matches the actual on-site business interaction, and summarize the data of the assessment points required for the process, we can complete the automatic construction of normal operation scenarios and fault scenarios, and the collaborative assessment and evaluation of central dispatchers and station duty personnel.

[0023] The basic signal simulation, station equipment, train onboard equipment, CTC center equipment, wireless block center, temporary speed limit server and disaster prevention system are organically combined on the simulated communication network in accordance with the standard interface method. According to the station duty personnel assessment and evaluation system architecture, the system architecture is generally divided into data service layer (DL), link adaptation layer (LL) and basic hardware layer (HL), such as Figure 4 shown.

[0024] The architectural design of the basic hardware layer is the foundation of the assessment and training platform. It is designed in detail according to the access layer, network layer and hardware layer to support the access requirements between various business systems, meet the environment and performance requirements of business software operation, and support the scalability requirements of the training platform.

[0025] The architectural design of the connection adaptation layer is the core of the assessment and training platform. By studying the central bus structure (V-CentralBus) used to adapt basic signal simulation, CTCS system simulation, and CTC simulation, and injecting real signal data, it is possible to fully reproduce all static trackside signal equipment on the line, including the position and status of track circuits, signal machines, switches, transponders, phase separation zones, and other equipment. Through the adaptation engine model (V-Engine) of train simulation and train control equipment, all signals and train control equipment are organically integrated to drive the train on the virtual line. By combining V-CentralBus and V-Engine and adding real-world signal data from the field, a virtual reality line built entirely according to standards is constructed to support the implementation of the intelligent assessment platform.

[0026] The architectural design of the business data layer is the focus of the assessment and training platform. By implementing logical operations and data interfaces between the train control system, interlocking system, and CTC, a business interface consistent with the real production environment is constructed for dispatchers and station attendants, meeting the requirements of non-differentiation in the operating interface and style of the train driving training room.

[0027] The software design mainly drives the normal operation of the CTC system, train control system and interlocking system through signal infrastructure equipment and train operation simulation equipment, and builds a self-service drill environment.

[0028] At the same time, through the research on fault scenario construction technology, intelligent job coordination technology and automatic assessment technology, intelligent assessment for different emergency scenarios is realized, which specifically includes the following modules: Figure 1 and Figure 2 As shown: Signal infrastructure simulation, including: The signal basic simulation equipment simulates the actual line data as a basis, builds stations and bridges consistent with the actual location in the virtual environment, and draws a line topology consistent with the real station type, simulates the dynamic operation of trains in the dispatching section, automatically generates train occupancy, clearance and signal closure status in sequence, simulates the code change information within the station and the section code change information, thus laying the foundation for the construction of train operation, dispatching and vehicle service simulation.

[0029] Train operation simulation, including: Train operation simulation, developed by simulating a train's traction and braking model, accepts data from track circuits and signals within a signal-based simulation environment and generates a real-time continuous speed control curve for target distance. This allows for monitoring train speed using service and emergency braking to prevent overspeeding. In the event of a signal closure, red light on a track circuit, or line blockage, the train will stop at a closed signal or occupied track circuit.

[0030] Automatic scene construction technology, including: Based on the statistical analysis of emergency drill assessments in recent years, the corresponding rules and regulations covered by each scenario are sorted out, and data compilation and processing flow calculations are carried out for the assessment scenarios.

[0031] Example 2 Take the "approaching turnout loses indication" fault scenario as an example: 1. Scenario construction: The teacher computer sets the switch failure in the scenario editing module, sets the trigger condition as "after processing the train access route", and configures the train operation plan.

[0032] 2. Trainee operation: The trainee goes to the CTC train terminal to process the train pick-up route. When the system detects that the switch is out of meter, it will display a fault prompt. The trainee needs to contact the electrical department, register the transport system 46, and prepare to guide the train pick-up according to the process.

[0033] 3. Job coordination: The system automatically simulates the electrician’s response of “Understood, will handle it immediately” and generates the Operation and System 46 registration interface for the trainees to fill in.

[0034] 4. Assessment process: The system checks the operation steps (such as whether to contact the electrical department before registering) and interlocking operations (such as the timing of opening the pilot signal) in real time, deducts points for incorrect operations, and automatically generates a scoring report after completion, pointing out the trainees' problems in "timeliness of fault reporting" and "completeness of filling in the Operation System 46" and other aspects.

[0035] Beneficial effects: 1. Improved assessment efficiency and fairness: Compared to traditional human-to-human question-and-answer assessments (average 75 minutes), the system's assessment time is shortened to 45 minutes, and the scores are automatically generated by a computer, eliminating human subjective bias.

[0036] 2. Enhance the targeted nature of training: Through big data analysis, we can identify students' weaknesses, such as incorrect signal terminal operation and untimely notifications, provide personalized reinforcement training, and effectively improve the professional capabilities of on-duty personnel through the comprehensive emergency scenarios that have been produced.

[0037] 3. Reduce safety risks: Simulate equipment failure scenario training to reduce on-site operational errors. This is expected to reduce the rate of traffic accidents caused by improper operation and ensure railway transportation safety.

[0038] 4. Improve resource utilization: The system is isolated from the actual signal system and can be freely practiced 24 hours a day. It supports single-station stand-alone or networked competitions, saving labor costs and relieving the pressure on vocational education staff.

[0039] The above specific implementation methods further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific implementation methods of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
