Description

Technical Field

[0001] This invention relates to the field of distance learning, specifically to a semi-automatic block circuit wireless distance learning platform. Background Technology

[0002] As a key component of railway signaling systems, block circuits function precisely to control the occupancy and vacancy status of tracks in a section, thereby ensuring safe isolation and orderly connection of train operations between adjacent stations. They are mainly divided into three categories: semi-automatic block, automatic block, and manual block. Among these, semi-automatic block circuits are widely used in short- and medium-distance railway lines and branch lines due to their moderate equipment cost, clear operating logic, and high safety and reliability. Their working principle involves using the electrical interlocking relationship between the equipment at both ends of the station. After obtaining the necessary block signaling permits, station personnel manually operate the relevant equipment to issue a train operation permission signal, allowing the train to occupy the section. The semi-automatic block system automatically locks the section to prevent subsequent trains from entering until the train reaches the other station and completes the block release procedure. Only then does the section return to an open state for the next use. The coordinated operation of core components in this circuit system, such as the relay engagement and release logic, the signal light display switching, and the track circuit status feedback, directly determines the safety and efficiency of train operation. This is a core content that needs to be mastered in railway signaling major education. By deeply understanding the composition principle, electrical characteristics, and fault response mechanism of the semi-automatic block circuit, students can lay a solid foundation for subsequent practical work such as railway signaling equipment installation, commissioning, maintenance, and troubleshooting.

[0003] There are two main approaches to teaching semi-automatic block circuits. One is the on-site teaching model based on physical circuits. This model typically relies on building a semi-automatic block circuit device that matches the actual railway signaling system. Teachers explain the structure, wiring, and working principle of the physical device on-site, guiding students to directly perform practical training such as parameter adjustment and fault diagnosis. The other is the simulation teaching model based on computer software. This model develops semi-automatic block circuit simulation software on computers, presenting the circuit's working process and fault status in a digital form. Students complete simulation training by operating the software interface. Some software also supports simple online interaction functions between teachers and students. However, the existing teaching models mentioned above all have significant shortcomings: the physical circuit teaching model is limited by the high cost and large footprint of physical equipment, making it difficult to promote large-scale teaching. Furthermore, setting faults in physical equipment requires manual adjustment of wiring or replacement of components, which is cumbersome and the types of faults are limited. In addition, the fixed location limit makes it unsuitable for remote teaching scenarios. While the computer software simulation teaching model solves the problems of location and cost, most simulation software is purely digital and fails to accurately reproduce the electrical characteristics, component operation logic, and electrical manifestations of actual semi-automatic block circuits. This results in a significant difference between students' hands-on experience and actual on-site operation, making it difficult to effectively cultivate students' practical operation and fault diagnosis abilities. In addition, the interactive functions of existing software are mostly limited to one-way transmission of teaching content, lacking real-time control of the circuit simulation process by teachers, accurate fault setting, and real-time feedback and assessment mechanisms for student operation data. The lack of in-depth two-way interaction between teachers and students fails to guarantee the effectiveness of remote teaching.

[0004] With the railway industry's increasing demands for practical skills among professionals and the widespread adoption of distance learning, there is an urgent need for a semi-automatic block circuit teaching solution that can balance the realism of actual circuit simulation, the convenience of distance learning, and the effectiveness of teacher-student interaction. This solution aims to address the technical problems of high cost, limited space, insufficient simulation realism, and poor interactivity in existing teaching models. Summary of the Invention

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.

[0021] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a wireless remote teaching platform for semi-automatic block circuits, including a teacher-end device, a student-end device, a wireless communication module, and a semi-automatic block circuit simulation module. The teacher-end device is communicatively connected to the wireless communication module, the wireless communication module is communicatively connected to the student-end device, the teacher-end device is communicatively connected to the semi-automatic block circuit simulation module, and the semi-automatic block circuit simulation module is communicatively connected to the wireless communication module. The semi-automatic block circuit simulation module is used to simulate the electrical characteristics and operating state of an actual semi-automatic block circuit. The teacher-end device includes a teacher control unit, a teacher display unit, a teacher input unit, and a teacher data processing unit. The teacher control unit is communicatively connected to the teacher display unit, the teacher input unit, and the teacher data processing unit, respectively. The teacher data processing unit is communicatively connected to the wireless communication module. The teacher input unit is used for the teacher to input teaching control commands and circuit parameter configuration commands, and the teacher display unit is used to display teaching content and feedback information from the student-end device.

[0022] Specifically, the core working principle of this semi-automatic block circuit wireless remote teaching platform is to achieve teaching and simulation of semi-automatic block circuits in remote teaching scenarios through the collaboration of multiple modules. The teacher-end device serves as the core of teaching control, where teachers input teaching control commands and circuit parameter configuration commands through the teacher input unit. After receiving the commands, the teacher control unit performs preliminary processing and transmits them to the teacher data processing unit. The teacher data processing unit encapsulates the commands and transmits them to the semi-automatic block circuit simulation module or the student-end device through a communication link with the wireless communication module. The semi-automatic block circuit simulation module, as the core simulation component, receives circuit parameter configuration commands and other commands sent by the teacher-end device and accurately simulates the electrical characteristics and working status of the actual semi-automatic block circuit. At the same time, the teacher display unit of the teacher-end device displays teaching content and feedback information such as operations and problems from the student-end device in real time. The wireless communication module, as the data transmission hub, enables bidirectional communication between the teacher-end device and the student-end device, and between the teacher-end device and the semi-automatic block circuit simulation module, ensuring the effective transmission of teaching commands, simulation status data, and feedback information. This establishes a complete teaching principle chain that integrates remote control by the teacher, accurate circuit simulation, and teacher-student information interaction.

[0023] The student terminal device includes a student control unit, a student display unit, a student input unit, and a student data processing unit. The student control unit is communicatively connected to the student display unit, the student input unit, and the student data processing unit, respectively. The student data processing unit is communicatively connected to the wireless communication module. The student input unit is used for students to input operation instructions and problem feedback information. The student display unit is used to display the teaching content sent by the teacher terminal device and the simulation status of the semi-automatic block circuit simulation module.

[0024] Specifically, the system achieves information reception, student operation, and feedback interaction in remote teaching through the collaboration of various units. The wireless communication module acts as a data transmission bridge, transmitting the teaching content sent by the teacher's device and the real-time simulation status of the semi-automatic block circuit simulation module to the student data processing unit. The student data processing unit parses and processes the received information and then transmits it to the student control unit. The student control unit drives the student display unit to clearly present the teaching content and circuit simulation status, allowing students to intuitively obtain teaching information. At the same time, students can input operation commands for the simulation circuit or feedback information on problems encountered during the learning process through the student input unit. This information is initially processed by the student control unit and then transmitted to the student data processing unit. The student data processing unit encapsulates the information and transmits it back to the teacher's device or the semi-automatic block circuit simulation module through the wireless communication module, realizing two-way data interaction between students and teachers, and between students and the simulation module, completing the closed loop of learning operation and information feedback in remote scenarios.

[0025] The wireless communication module includes a communication protocol conversion unit, a signal amplification unit, and an anti-interference unit. The communication protocol conversion unit is communicatively connected to the signal amplification unit and the anti-interference unit. The communication protocol conversion unit is used to achieve communication protocol matching between the teacher's device, the student's device, and the semi-automatic block circuit simulation module. The signal amplification unit is used to enhance the wireless communication signal strength, and the anti-interference unit is used to filter interference signals in wireless communication.

[0026] Specifically, the system ensures the compatibility, stability, and reliability of data transmission between teacher-side devices, student-side devices, and the semi-automatic block circuit simulation module through the collaborative efforts of each unit. The communication protocol conversion unit, as the core of protocol adaptation, receives the raw data transmitted from each end, identifies the communication protocol types of different devices, and performs conversion processing to achieve protocol matching between the devices, ensuring accurate data identification. The signal amplification unit enhances the strength of the converted signal to be transmitted or the weak received signal, improving the signal transmission distance and stability and avoiding signal attenuation caused by long-distance transmission. The anti-interference unit simultaneously filters and purifies noise, electromagnetic interference, and other interference signals during transmission, reducing the impact of interference on data transmission. The coordinated operation of the communication protocol conversion unit, signal amplification unit, and anti-interference unit constructs an efficient and stable wireless communication link between the devices, ensuring the accurate transmission of teaching instructions, simulation data, and feedback information.

[0027] The semi-automatic block circuit simulation module includes a circuit parameter configuration unit, a state simulation unit, a fault setting unit, and a data acquisition unit. The circuit parameter configuration unit is communicatively connected to the state simulation unit, the fault setting unit is communicatively connected to the state simulation unit, the data acquisition unit is communicatively connected to the state simulation unit, and the data acquisition unit is communicatively connected to the wireless communication module. The circuit parameter configuration unit is used to configure the resistance, capacitance, and inductance parameters of the simulation circuit, and the fault setting unit is used to set the short circuit, open circuit, and poor contact fault states of the simulation circuit.

[0028] Specifically, the system achieves accurate simulation and data feedback of the actual semi-automatic block circuit through the collaboration of various units. The circuit parameter configuration unit receives external instructions and accurately configures the core electrical parameters of the simulated circuit, such as resistance, capacitance, and inductance, providing basic electrical characteristic support for circuit simulation. The fault setting unit receives instructions synchronously and sets fault states such as short circuit, open circuit, and poor contact in the simulated circuit according to requirements, making the simulation scenario more closely resemble actual applications. The outputs of both the circuit parameter configuration unit and the fault setting unit are transmitted to the state simulation unit. The state simulation unit reproduces the operating state of the actual semi-automatic block circuit based on the configured electrical parameters and set fault states. The data acquisition unit collects the operating data and status information of the state simulation unit in real time, processes it, and transmits it to the teacher's and student's devices through the wireless communication module, providing data support for status observation, operation guidance, and result evaluation during the teaching process. The linkage of various units realizes a complete simulation link from parameter configuration and fault setting to state simulation and data acquisition.

[0029] The teacher-side device also includes a teacher storage unit, which is communicatively connected to the teacher data processing unit. The teacher storage unit stores teaching materials, circuit simulation data, student learning records, and assessment data. The student-side device also includes a student storage unit, which is communicatively connected to the student data processing unit. The student storage unit stores received teaching materials, its own operation records, and simulation experiment data.

[0030] Specifically, the system achieves centralized storage and retrieval of various teaching-related data through communication with the teacher data processing unit. During the teaching process, the teacher data processing unit receives and organizes teaching courseware, circuit simulation data transmitted by the semi-automatic block circuit simulation module, learning records fed back by student devices, and assessment data generated by the assessment and evaluation module. This data is then synchronized in real time to the teacher storage unit for classification and storage, allowing teachers to retrieve the data later for teaching review, learning analysis, and optimization of teaching content. The student storage unit completes local storage of personalized learning data through communication with the student data processing unit. After receiving teaching courseware sent by the teacher devices, operation records generated by students through the input unit, and simulation experiment data fed back by the semi-automatic block circuit simulation module, the student data processing unit transmits this data to the student storage unit for retention. This allows students to easily review teaching content, recall their own operation process, and analyze experimental data, helping them consolidate learning outcomes and improve their self-learning ability. The two types of storage units provide data storage support for teacher teaching management and student self-learning, ensuring the traceability of the teaching process and the continuity of learning.

[0031] It also includes an assessment module, which communicates with the teacher data processing unit on the teacher's device. This module receives operational data from the student's device and scores the student's operational accuracy and troubleshooting ability based on preset assessment standards. The state simulation unit includes a relay simulation subunit, a signal machine simulation subunit, and a track circuit simulation subunit. The relay simulation subunit simulates the activation and deactivation states of relays; the signal machine simulation subunit simulates the red, yellow, and green light display states of the signal machine; and the track circuit simulation subunit simulates the occupied and idle states of the track circuit.

[0032] Specifically, the assessment module establishes a communication link with the teacher's data processing unit on the teacher's end device, receiving real-time operation data from the student's end device transmitted through the teacher's data processing unit. This module has built-in preset assessment standards and automatically scores students based on core indicators such as operational accuracy, fault diagnosis process completeness, and problem-solving efficiency in the semi-automatic block circuit simulation scenario. The scoring results can be fed back to both the teacher's and student's ends, providing a basis for teaching effectiveness evaluation and personalized guidance. The state simulation unit, as the core execution component of the semi-automatic block circuit simulation module, reproduces the states of key components in the actual circuit through the collaborative work of the internal relay simulation subunit, signal simulation subunit, and track circuit simulation subunit. The relay simulation subunit simulates the activation and deactivation of relays according to the circuit control logic, the signal simulation subunit displays the corresponding red, yellow, and green lights according to the circuit operation status, and the track circuit simulation subunit switches the occupied and idle states of the track circuit according to the needs of the simulation scenario. Together, the three construct a semi-automatic block circuit operation environment that closely resembles reality, providing a realistic simulation foundation for students' practical training and assessment.

[0033] It also includes a data synchronization module, which is connected to the teacher's device, the student's device, and the semi-automatic block circuit simulation module. The data synchronization module is used to synchronize the teacher's device commands, the student's device operation data, and the simulation status data of the semi-automatic block circuit simulation module in real time.

[0034] Specifically, the data synchronization module establishes a real-time data synchronization mechanism across the entire link by establishing communication connections with the teacher's device, student's device, and semi-automatic block circuit simulation module. Its core is the real-time collection and distribution of various commands issued by the teacher's device, such as teaching control commands and circuit parameter configuration commands; operational commands and problem feedback information input by the student's device; and simulation status data such as electrical characteristic simulation data, fault status data, and component operating status data output by the semi-automatic block circuit simulation module. This ensures that the teacher's device can promptly obtain student operational data and the simulation module's operating status, that the student's device can synchronously receive teacher commands and the simulation module's real-time status, and that the simulation module can accurately respond to the command signals from both the teacher and students. This eliminates data transmission delays and information asymmetry between devices during remote teaching, ensuring the consistency and immediacy of the entire teaching process.
