Description
Technical Field
[0001] This utility model relates to the field of early warning technology for railway platforms, specifically a train sensing warning system. Background Technology
[0002] Currently, railway platforms generally suffer from delayed warning responses and limited coverage. Traditional warning methods mainly rely on manual observation or fixed-location sensors, which have the following drawbacks:
[0003] ① The monitoring range is limited, making it impossible to achieve long-distance dynamic sensing along the track;
[0004] ② The warning methods are too simplistic; relying solely on broadcasts or static indicator lights is insufficient to attract passengers' full attention.
[0005] ③ The system relies on wired power supply, which makes it difficult to deploy in remote sections. Especially when multiple trains enter the station at the same time, the existing system has difficulty accurately locating the distance of the nearest train, which can easily lead to platform personnel misjudging the safe area.
[0006] Therefore, we propose a train sensor warning system to solve the above problems. Utility Model Content

A cover plate 22 is fastened to the top of the housing 19. The radar sensor 23 is installed on the upper surface of the cover plate 22. Inside the hole; the marker includes a housing 1, a signal receiver 7, and a display panel 3. Both ends of the lower surface of the housing 1 are fixedly installed with housing support frames 2 by bolts 17. The housing 1 has a rectangular channel structure. Inside the housing 1, a signal receiver fixing plate 6, a light panel support frame 8, and a battery 5 are respectively installed by bolts 17. The signal receiver 7 is installed inside the housing 1 through the signal receiver fixing plate 6. The display panel 3 is fixedly installed on the front side wall of the housing 1 by snap-fit. The back plate 13 is fixedly installed on the rear side wall of the housing 1 by bolts 17. A controller 24 is set inside the housing 1 and the controller 24 is fixedly installed on the side wall of the back plate 13.
[0032] The battery 5 is charged by the solar panel 4 and the charge / discharge controller 24. At the same time, the battery 5 inside the trigger is electrically connected to the circuit board 21 through the series connection of the inverter and the push switch 18, and is electrically connected to the radar sensor 23 through the circuit board 21. Meanwhile, the battery 5 inside the marker is electrically connected to the controller 24 through the inverter, and is electrically connected to the signal receiver 7, the speaker 10, the display board 3, the vertical light board 14 and the sheet light board 9 through the controller 24.
[0033] The function of solar panel 4 is to convert the sun's radiation into electrical energy, which can then be stored in battery 5 or used to power loads.
[0034] The circuit board 21 contains a microcontroller and a signal generator.
[0035] Controller 24 uses a control chip conventional in the art;
[0036] Radar sensor 23 is an integrated system that must contain:
[0037] Transmitter: Used to generate and transmit electromagnetic radar waves;
[0038] Receiver: Used to receive weak electromagnetic wave echoes reflected from a target;
[0039] Antenna: Typically, a single antenna is used for both transmitting and receiving, switched via a transmit / receive switch, or separate transmit / receive antennas are used. The antenna is responsible for converting electrical signals into electromagnetic waves that propagate through space during transmission, and for converting electromagnetic waves propagating through space back into electrical signals during reception.
[0040] The core principle of radar is based on the transmission, propagation, reflection, and reception of radio waves:
[0041] Transmitting electromagnetic waves: Radar transmitters generate electromagnetic pulses or continuous waves at specific frequencies, usually in the microwave band, such as 24 GHz, 77 GHz, and 79 GHz.
[0042] Beamforming and transmission: The generated electromagnetic waves are focused into a beam in a specific direction by the antenna and transmitted out, propagating in space.
[0043] Target reflection: When emitted electromagnetic waves encounter targets such as vehicles, pedestrians, walls, aircraft, raindrops, etc., some of the energy is reflected back. The intensity of the reflection depends on the target's size, shape, material, especially its dielectric constant and conductivity, as well as the angle between the radar wave and the target's surface and its radar cross section.
[0044] Receiving echoes: The radar's receiving antenna may be the same antenna that captures the weak electromagnetic wave echoes reflected back from the target.
[0045] Signal processing and analysis: The receiver amplifies the weak echo signal and compares and analyzes it with the original transmitted signal. Target information is calculated by measuring key parameters.
[0046] When the solenoid valve emitted by the radar detector in the trigger along a fixed direction encounters a train, it generates an echo. When the radar detector receives the echo, it processes and analyzes the signal to determine the distance of the echo and converts the distance information into an electronic signal, which is then transmitted to the circuit board 21. The signal generator inside the circuit board 21 then transmits the electronic signal to the signal receiver inside the marker. At this time, the signal receiver 7 transmits the electronic signal to the controller 24, which analyzes the electronic signal and then displays the distance information on the display panel 3. At the same time, the circular light group formed by the speaker 10, the vertical light panel 14, and the sheet light panel 9 provide sound and light reminders to warn the waiting passengers on the platform.
[0047] As a preferred technical solution of this utility model, the light panel includes a sheet light panel 9 and a vertical light panel 14. The sheet light panel 9 is fixedly installed on the surface of the back plate 13 by bolts 17. Multiple sets of vertical light panels 14 are arranged in a circle to form a circular light group, and the circular light group extends through the groove on the upper surface of the box 1 to the top of the box 1. Each vertical light panel 14 is fixedly installed on the surface of the light panel support frame 8 by a light panel fixing plate 16 and bolts 17. The sheet light panel 9 and the vertical light panel 14 enable the sign to provide light warnings to the platform.
[0048] As a preferred technical solution of this utility model, the outer side of the circular lamp assembly is fitted with a lamp cover 15 that is threadedly engaged with the upper surface of the box 1, and the lamp cover 15 can provide external protection for the circular lamp assembly.
[0049] As a preferred technical solution of this utility model, a solar panel 4 is installed on the upper surface of the cover plate 22, and a solar panel 4 is also installed on the upper surface of the box body 1. The solar panels 4 are electrically connected to the battery 5 through the charge and discharge controller 24, and the battery 5 is charged through the solar panels 4 and the charge and discharge controller 24.
[0050] As a preferred technical solution of this utility model, a speaker 10 is installed at one end of the inner side wall of the box body 1, and a loudspeaker hole 11 is opened at the corresponding position on the outer side wall of the box body 1. The speaker 10 can enable the sign to give an audible warning to the platform, and the loudspeaker hole 11 can increase the warning range of the speaker 10.
[0051] As a preferred technical solution of this utility model, a dust cover 12 is provided on the outer side wall of the box body 1, and the dust cover 12 covers the loudspeaker hole 11. By covering the loudspeaker hole 11 with the dust cover 12, the loudspeaker hole 11 can be protected from wind and dust, and the loudspeaker hole 11 can be prevented from being blocked.
[0052] As a preferred technical solution of this utility model, the box support frame 2 is a rectangular groove structure with two symmetrically arranged bottom openings, and the outer shell support frame 20 is a geometric structure. The box support frame 2 formed by the two rectangular groove structures supports the box 1. The geometric structure can improve the placement stability of the outer shell support frame 20.
[0053] As a preferred technical solution of this utility model, the display panel 3 is a touch display. The display panel 3 is electrically connected to the battery 5 through the controller 24. By using the touch display panel 3, the sign can have intelligent display function.
[0054] The working principle of this utility model is as follows: The marker is fixedly installed at the platform, and the triggers are fixed at equal intervals, for example, 500m, near the rails. At this time, the radar sensor 23 is in standby mode. When the solenoid valve emitted by the radar detector in the trigger along a fixed direction encounters a train, an echo is generated. When the radar detector receives the echo, it processes and analyzes the signal to determine the distance of the echo and converts the distance information into an electronic signal, which is then transmitted to the circuit board 21. The signal generator inside the circuit board 21 then transmits the electronic signal to the signal receiver inside the marker. At this time, the signal receiver 7 transmits the electronic signal to the controller 24, and the controller 24 analyzes the electronic signal. The distance information is then displayed on the display panel 3. At the same time, the circular light group formed by the speaker 10, the vertical light panel 14, and the sheet light panel 9 provide sound and light reminders to warn the waiting passengers on the platform.

Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
