Description

Technical Field

[0001] This invention relates to the field of teaching and training technology for fire alarm systems in high-speed trains, specifically to a teaching device for the address code of a fire detector in a high-speed train. Background Technology

[0002] Fire detectors on high-speed trains are key equipment for ensuring the safe operation of trains. Their address code encoding logic and alarm principle are core knowledge that ground mechanics must master.

[0003] However, the Guangzhou EMU Depot currently faces the following problems: First, the training facilities lack equipment related to smoke and fire alarm devices, making it impossible to conduct hands-on teaching; second, the fire detectors in the operational train sets cannot be removed at will, and the address code positions are too small, which is not conducive to on-site demonstrations and hands-on operation; third, traditional teaching methods cannot intuitively demonstrate the address code setting rules and alarm principles, resulting in mechanics' understanding of fire detectors remaining superficial, making it difficult to achieve the training goal of "everyone hands-on, everyone masters".

[0004] Currently, there is no dedicated teaching device for the address codes of fire detectors on high-speed trains. Relying on traditional teaching methods and limited on-vehicle observation results in poor training effectiveness, hindering ground mechanics from mastering relevant practical skills and posing potential risks to the safe operation of high-speed trains. Therefore, developing a teaching device for the address codes of fire detectors on high-speed trains that allows for intuitive demonstration and hands-on operation is of great significance for improving training effectiveness and ensuring the safe operation of high-speed trains.

[0005] Therefore, developing a system specifically for teaching the address codes of fire detectors on high-speed trains is of great significance for improving training effectiveness and ensuring the safe operation of high-speed trains. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To overcome the shortcomings of existing technologies, a teaching device for address codes of fire detectors on high-speed trains is proposed to address the technical problems of the lack of dedicated physical teaching equipment, inconvenient operation and demonstration of actual train equipment, and lack of intuitiveness and interactivity in teaching methods, which lead to poor training results and insufficient practical skills for ground mechanics.

[0008] (II) Technical Solution

[0009] This invention is achieved through the following technical solution: This invention proposes a teaching device for the address code of a fire detector on a high-speed train, including an enlarged fire detector module, a receiver module, and a computer software platform. The enlarged fire detector module and the receiver module establish a data connection through wireless communication, and the receiver module and the computer software platform establish a data connection through serial communication.

[0010] The enlarged fire detector module includes a carrier box and a detachable cover plate on its top. A DIP switch and an confirmation button are located on the outside of the cover plate. The carrier box integrates a relay I / O module, a smoke and temperature detection alarm module, a data transmission radio remote transmission module, and a first 12V power supply, which powers all internal components of the enlarged fire detector module. The receiver module includes a mounting box, which integrates a data transmission radio remote transmission module, an antenna, a second 12V power supply, and a serial transmission conversion module that are compatible with the enlarged fire detector module. The second 12V power supply powers all internal components of the receiver module.

[0011] The computer software platform includes a computer body and McgsPro configuration software and serial communication driver installed inside it. It is used to receive signal data transmitted by the receiver module and realize address code parsing, visualization display and dynamic simulation of fire alarm principle.

[0012] Furthermore, the DIP switch consists of eight binary toggle switches, which are arranged linearly on the front of the enlarged fire detector module, and the confirmation button is located on one side of the eight binary toggle switches.

[0013] Furthermore, the signal input terminal of the relay IO module is electrically connected to the DIP switch, and the signal output terminal is electrically connected to the remote transmission module of the data transmission radio; the smoke and temperature detection alarm module is electrically connected to the remote transmission module of the data transmission radio, and is used to simulate the alarm signals of smoke and temperature detection and send them to the receiving box module.

[0014] Furthermore, the serial transmission conversion module is a USB-RS485 conversion module, whose input end is electrically connected to the data transmission radio remote transmission module of the receiver module, and whose output end is electrically connected to the host of the computer software platform through a USB interface.

[0015] Furthermore, the enlarged fire detector module and the receiver module transmit data via Modbus RTU or Modbus TCP communication protocols.

[0016] Furthermore, the McGsPro configuration software includes a data binding unit and a real-time refresh unit. The data binding unit binds the received switch status data to the interface display controls, and the refresh period of the real-time refresh unit is configured to be on the order of 100ms.

[0017] Furthermore, the McGsPro configuration software also includes an address code parsing and mapping unit, which parses the switch status data based on the 8421 binary code system and converts the binary code into a decimal or hexadecimal address code.

[0018] Furthermore, the address code parsing and mapping unit predefines the mapping relationship between the address code and the physical location of the fire detector in the train set, and can synchronously display the correspondence between the switch position, binary code, address code and detector position on the software interface.

[0019] Furthermore, the McGsPro configuration software also includes a fault simulation unit and a practical assessment scoring unit. The fault simulation unit can simulate typical fault signals such as incorrect address codes, open circuits, and detection module failures of the fire detectors in the braking vehicle, and superimpose the fault signals with normal address code signals to transmit them to the software interface. The practical assessment scoring unit can perform real-time quantitative scoring based on the accuracy of the trainee's DIP code correction operation, fault location time, and alarm reset operation, and generate an assessment report.

[0020] Furthermore, the enlarged fire detector module is equipped with a standardized quick-release interface on its housing. The quick-release interface is electrically connected to the signal end of the data transmission radio remote transmission module. The enlarged fire detector module supports parallel networking of multiple modules through the quick-release interface. Multiple enlarged fire detector modules can simultaneously establish wireless communication connections with the same receiver module, and the computer software platform can independently analyze and display the switch status and alarm signals of each module in a split-screen manner.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] 1. A teaching device for address codes of fire detectors on high-speed trains. This invention enables trainees to operate the fire detector module by means of a proportionally enlarged module. Combined with the visualization display of the computer software platform, the address code encoding logic and alarm principle are transformed from abstract to concrete, allowing trainees to intuitively grasp the address code setting rules. This solves the problem of superficial understanding in traditional teaching and achieves the training goal of "everyone does it themselves and everyone masters it".

[0024] 2. A teaching device for fire detector address codes on high-speed trains. 2. Ensuring training safety: This invention is a dedicated teaching and training device that does not require the removal of fire detectors in the operating train, avoids modifications to the actual vehicle's safety equipment, eliminates safety risks associated with actual vehicle operation, and uses a 12V low-voltage power supply, eliminating operational safety hazards.

[0025] 3. A teaching device for address codes of fire detectors on high-speed trains. This invention adopts a modular structure design, with an enlarged fire detector module, receiver box module, and computer software platform working independently yet collaboratively. The software parsing rules and hardware modules can be adapted and adjusted according to the characteristics of fire detectors of different train models. It can also integrate other safety system teaching modules to expand the teaching scenarios.

[0026] 4. A teaching device for address codes of fire detectors on high-speed trains. The enlarged fire detector module of this invention is manufactured using 3D printing, allowing for assembly of components using faulty parts. This reduces manufacturing costs, and all components can be repeatedly disassembled and reused, improving resource utilization. Furthermore, this invention can simulate the alarm and fault states of fire detectors on high-speed trains. Through practical training, trainees master the correspondence between address codes and detector locations, directly applying their knowledge to actual fault handling of fire detectors on high-speed trains. This effectively improves on-site fault handling efficiency and ensures the safe operation of high-speed trains.

[0027] 5. A teaching device for address codes of fire detectors on high-speed trains. This invention breaks through the limitations of existing teaching devices that can only demonstrate address codes and simulate normal alarms. It integrates teaching, fault simulation, and practical assessment, allowing trainees to directly conduct fault troubleshooting training while mastering basic coding logic. Furthermore, it allows for intuitive evaluation of training results through quantitative scoring. Compared to traditional teaching methods without assessment or fault simulation, this device aligns training with actual work scenarios, significantly improving trainees' fault-handling abilities. Secondly, it addresses the problem that existing teaching devices can only support single-person operation with a single module, and group training can only be conducted via projection, preventing multiple trainees from practicing simultaneously. Through multi-module networking, multiple trainees can simultaneously perform independent dialing and alarm simulation exercises. Combined with computer split-screen display, instructors can simultaneously guide multiple trainees. Compared to the traditional "one person operates, multiple people watch" group training model, this significantly improves practical participation and training efficiency, truly achieving the training goal of "everyone hands-on, everyone practices."

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] like Figure 1-5 As shown, the present invention provides a technical solution: a teaching device for address codes of fire detectors on high-speed trains, including an enlarged fire detector module 1, a receiver module 2, and a computer software platform 3. The enlarged fire detector module 1 and the receiver module 2 establish a data connection through wireless communication, and the receiver module 2 and the computer software platform 3 establish a data connection through USB-RS485 serial communication, realizing the full-process data transmission from hardware operation signals to software visualization.

[0036] In this embodiment, the enlarged fire detector module 1 includes a carrier box 17 and a detachable cover plate 18 on its top. The cover plate 18 is equipped with a DIP switch 11 and a confirmation button 12. Eight binary DIP switches 11 are linearly arranged on the front of the cover plate 18. One confirmation button 12 is located on the right side of the eight binary DIP switches 11, which facilitates manual DIP switching and operation confirmation by the trainee. The carrier box 17 integrates a relay IO module 13, a smoke and temperature detection alarm module 14, a first data transmission radio remote transmission module 15, and a first 12V power supply 16. The first 12V power supply 16 provides a stable low-voltage power supply to the relay IO module 13, the smoke and temperature detection alarm module 14, and the first data transmission radio remote transmission module 15, without any operational safety risks.

[0037] In this embodiment, the signal input terminal of the relay IO module 13 is electrically connected to eight binary toggle switches 11, and the signal output terminal is electrically connected to the first data transmission radio remote transmission module 15. When the student toggles the DIP switch 11, the relay IO module 13 collects the on / off state of each DIP switch 11 in real time and converts the mechanical on / off state into high / low level electrical signal data, which is then transmitted to the first data transmission radio remote transmission module 15. The smoke and temperature detection alarm module 14 is electrically connected to the first data transmission radio remote transmission module 15 and can simulate the alarm signals of smoke and temperature detection. After the student presses the confirmation button 12, the alarm signal of the smoke and temperature detection alarm module 14 can be synchronously sent to the receiving box module 2 through the first data transmission radio remote transmission module 15 to realize the practical training simulation of the alarm principle.

[0038] In this embodiment, the receiver module 2 is a portable box structure, which includes a mounting box 21 and a second data transmission radio remote transmission module 21, an antenna 22, a second 12V power supply 23, and a USB-RS485 serial transmission conversion module 24 integrated inside the mounting box 21. The second 12V power supply 23 supplies power to the second data transmission radio remote transmission module 21 and the serial transmission conversion module 24. The antenna 22 is connected to the second data transmission radio remote transmission module 21 to enhance the wireless communication signal and ensure the wireless data transmission distance and stability between the enlarged fire detector module 1 and the receiver module 2. The second data transmission radio remote transmission module 21 is matched with the first data transmission radio remote transmission module 15, and the two transmit data through the Modbus RTU communication protocol to ensure stable and real-time uploading of hardware status data and alarm simulation data.

[0039] In this embodiment, the serial transmission conversion module 24 is a USB-RS485 conversion module. Its input end is electrically connected to the second data radio remote transmission module 21 through an RS485 communication terminal, and its output end is electrically connected to the host of the computer software platform 3 through a USB interface, so as to realize the format conversion between wireless communication data and serial communication data, and at the same time complete the bidirectional data transmission between the receiver module 2 and the computer software platform 3.

[0040] In this embodiment, the computer software platform 3 is an industrial computer running a Windows system. It includes a computer body and McgsPro configuration software 31 and serial communication driver 32 installed inside it. The serial communication driver 32 ensures the serial communication compatibility between the receiver module 2 and the computer software platform 3. The McgsPro configuration software 31 is equipped with a data binding unit, a real-time refresh unit, and an address code parsing and mapping unit. The data binding unit binds the received switch status data and alarm simulation data to the display controls such as the digital display box, indicator lights, and address code lookup table on the software interface one by one. The refresh cycle of the real-time refresh unit is configured to 100ms to realize real-time data parsing and interface display, avoiding data delay from affecting the teaching effect.

[0041] In this embodiment, the address code parsing and mapping unit is the core functional unit of the computer software platform 3. It parses the switch status data based on the 8421 binary code system of the fire detector address encoding of the EMU, and converts the binary code formed by the on / off combination of the 8 binary toggle switches 11 into a decimal or hexadecimal address code. At the same time, the unit predefines the mapping relationship between the address code of the Fuxing CR400AF EMU and the physical location of the fire detector (the location of each detector in cars 1-8). The four-dimensional correspondence between switch position, binary code, address code and detector position is displayed synchronously on the software interface, allowing trainees to intuitively understand the setting rules and encoding logic of the address code.

[0042] In this embodiment, when trainees are conducting alarm principle training, the simulated alarm signal of the smoke and temperature detection alarm module 14 is transmitted to the McgsPro configuration software 31 after wireless transmission and serial conversion. The software interface will light up the alarm indicator light corresponding to the detector position and display the alarm address code. Trainees can realize the alarm reset operation through the alarm reset button on the software interface, which fully simulates the entire process of alarm, display and reset of the high-speed train fire detector.

[0043] The teaching device in this embodiment can be used individually for hands-on practice by students, or the operation interface of the computer software platform 3 can be demonstrated collectively through a projection screen, meeting different teaching needs for individual training and group training. Each module of the device can be repeatedly disassembled and assembled, and the parsing rules and mapping relationships of the address code parsing mapping unit can be adjusted in the McgsPro configuration software 31 according to the address encoding rules of fire detectors of other train models, so as to achieve teaching adaptation for different train models and have good scalability.

[0044] The teaching device of this invention can be applied to the practical teaching of fire detector maintenance and replacement in the training of EMU mechanics. It can also be used as an auxiliary teaching tool for EMU safety system courses. Through the practical training of this device, trainees can quickly master the address code encoding logic and alarm principle of EMU fire detectors and directly apply the knowledge they have learned to the actual fault handling of EMU fire detectors, effectively improving the efficiency of on-site fault handling and providing technical support for the safe operation of EMUs.
