Technical Field

[0001] This utility model relates to the field of rail transit teaching devices, and in particular to a general-purpose rail transit vehicle-mounted teaching device. Background Technology

[0002] Currently, the cost of onboard equipment for rail transit in my country is generally high. Most of this equipment is specifically designed for actual operational needs, rather than for teaching purposes. This leads to high costs and resource waste for educational institutions when purchasing rail transit onboard equipment. At the same time, this equipment lacks intuitiveness and interactivity, which hinders students' in-depth understanding and mastery of the operating principles and procedures of rail transit trains.

[0003] On the other hand, existing vocational education equipment for rail transit vehicle signaling generally uses virtual simulation for teaching, leaving students with limited opportunities for hands-on operation. This teaching method fails to meet the needs of vocational education talent training, as vocational education emphasizes students' practical abilities and operational skills. Furthermore, the lack of specialized experimental teaching equipment results in teachers using limited teaching methods, making it difficult to provide students with vivid and intuitive learning content. This situation severely impacts students' learning interest and enthusiasm, leading to an overall decline in teaching quality. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 A specific embodiment of a general-purpose teaching device for rail transit vehicles is shown below:

[0028] It includes: two steel rails 15 with a phase-sensitive rail circuit receiving end 10 and a phase-sensitive rail circuit sending end 9 connected to both sides respectively; a transponder 7 set between the two steel rails 15 for transmitting signals; a trolley 16 running on the two steel rails 15, a radar 6 installed at the front end of the trolley 16, test sensing wheels 1 on both sides of the bottom of the trolley 16, a transponder antenna 4 at the bottom of the trolley 16, and a speed sensor 2 installed on the trolley 16.

[0029] The vehicle-mounted host 17 uses a microcontroller as the core controller and is installed inside the car 16. The test sensor wheel 1, radar 6, transponder antenna 4 and speed sensor 2 are all electrically connected to the vehicle-mounted host 17; the human-machine interface 14 is connected to the vehicle-mounted host 17.

[0030] Specifically, the speed sensor 2 is used to detect the current running speed of the car 16 and transmit the speed information to the on-board host 17. After processing, the on-board host 17 transmits the running speed information to the human-machine interface 14 for display.

[0031] Specifically, radar 6 is used to detect obstacles in front of the vehicle 16 and transmits the obstacle information to the on-board host. After processing, the on-board host 17 transmits the obstacle information to the human-machine interface 14 for display.

[0032] Specifically, the transponder antenna 4 is used to receive and detect the signal beacon setting information emitted by the transponder 7, and transmit the information to the vehicle host 17. After processing, the vehicle host 17 transmits the signal beacon information to the human-machine interface 14 for display.

[0033] Specifically, the test sensor wheel 1 is used to receive and detect information from the receiving end 10 and the sending end 9 of the phase-sensitive track circuit, detect track electronic information (i.e., track integrity), and transmit the information to the on-board host 17. After processing, the on-board host 17 transmits the track electronic information to the human-machine interface 14 for display.

[0034] Specifically, the human-machine interface 14 display screen provides an interactive interface between the user and the teaching platform, making it convenient for the user to operate and set up.

[0035] Specifically, the vehicle-mounted host 17 uses a microcontroller as the core controller to receive input signals from various components (such as speed signals, line information, obstacle information, etc.), and after processing, issues corresponding control commands (such as display information, alarm information, etc.) to realize the linkage and control of the teaching platform.

[0036] In other preferred embodiments, the rear end of the trolley 16 is provided with a platform handrail 3.

[0037] Specifically, the platform handle 3 is used to facilitate the operator in pushing the trolley 16.

[0038] In other preferred embodiments, two sets of wheelsets 5 are installed on both sides of the bottom of the trolley 16, and the two sets of wheelsets 5 are slidably connected to the rail 15.

[0039] Specifically, wheelset 5 contacts the rail on rail 15 via the wheel axle, maintaining relative sliding with rail 15 to simulate a train running on the track.

[0040] In other preferred embodiments, insulating joints 8 are installed on both sides of the two rails 15.

[0041] Specifically, insulating joint 8 is an accessory for the track circuit. Insulating joint 8 divides the track circuit into multiple independent sections, each of which can transmit independent signal information, preventing information from being transmitted in two directions on the track and ensuring the accuracy of signal transmission.

[0042] In other preferred embodiments, the human-machine interface 14 includes a handheld radio 11, a DMI display interface 12, and a function operation keyboard 13.

[0043] Specifically, the handheld radio 11 is used to communicate indoors, similar to a walkie-talkie, for example, to report the experimental situation to the teacher or request help.

[0044] Specifically, the DMI display interface 12 is used to receive information processed by the on-board host 17 and display it in the form of graphics or text, such as the train's running speed, information on obstacles ahead, signal status, and track integrity information.

[0045] Specifically, the function keypad 13 is used to send commands to the vehicle host 17, such as setting the speed limit and selecting the analog signal type.

[0046] In other preferred embodiments, the radar 6 is a Doppler radar, the phase-sensitive track circuit receiving end 10 is a 50 / 25Hz phase-sensitive track circuit receiving end, and the phase-sensitive track circuit sending end 9 is a 50 / 25Hz phase-sensitive track circuit sending end.

[0047] Specifically, Doppler radar 6 can accurately measure the speed of a target, even if the target is stationary or moving at low speed; Doppler radar 6 has strong anti-jamming capabilities and can effectively eliminate the influence of environmental noise and interference signals; Doppler radar 6 can be used to measure parameters of various moving targets, such as train speed, direction, and distance.

[0048] Specifically, the 50 / 25Hz phase-sensitive track circuit has strong anti-interference capability, which can effectively eliminate noise interference in the track circuit; the 50 / 25Hz phase-sensitive track circuit has a long transmission distance, which can meet the long-distance transmission needs of rail transit lines; and the 50 / 25Hz phase-sensitive track circuit has high reliability, which can ensure the stability and safety of rail transit signal transmission.

[0049] This invention simulates a rail transit vehicle-mounted signaling system by connecting information acquisition devices such as speed sensors 2, transponder antennas 4, radar 6, and test sensing wheels 1 with onboard host, DMI display interface 12, and function operation keyboard 13, forming a complete rail transit vehicle-mounted signaling system model. Students can perform various operations through the interface, such as setting parameters, simulating train operation, and viewing train status, thereby gaining a deeper understanding of the principles and functions of rail transit vehicle-mounted signaling systems.

[0050] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
