[0036] The railway track condition monitoring device 10 provided in this application embodiment, such as Figure 1 As shown, it includes: a sensing module 11, a data processing module 12, and a status monitoring module 13. The sensing module 11 is connected to the data processing module 12, and the data processing module 12 is connected to the status monitoring module 13; wherein:
[0037] The sensing module 11 is deployed on the railway track to detect at least one of the following: track stress distribution, track deformation, and track defects, generate railway track data, and send the railway track data to the data processing module 12.
[0038] The railway track data includes at least one of the following: railway track stress data, railway track deformation data, and railway track defect data.
[0039] Optionally, the sensing module 11 includes at least one of a stress sensing module, a radar deformation detection module, and an eddy current flaw detection sensing module.
[0040] The stress sensing module includes multiple stress sensors arranged in an array, and is deployed within the track pad of the railway track.
[0041] Optionally, the number of stress sensors can correspond to the length of the railway track, specifically, the number of stress sensors is positively correlated with the length of the railway track. For example, the number of stress sensors can be 96 (12 rows × 8 columns).
[0042] In this way, stress measurement at various locations in the railway track can be achieved using stress sensors.
[0043] As one embodiment, the stress sensor is embedded and fixed in a reserved cavity inside the railway track, wherein the cavity can be honeycomb-shaped.
[0044] This ensures that the stress sensor can directly measure the stress on the railway track, but will not be damaged by trains or locomotives traveling on the track.
[0045] Optionally, the stress sensing module is connected to a multi-channel waterproof connector on the sidewall of the pad via flexible shielded wires.
[0046] Optionally, the radar deformation detection module includes a housing, a rubber pad, and a radar processing component, with the radar processing component and the rubber pad built into the housing, and the housing being fixed to the rail web of the railway track by a clamp.
[0047] In this way, the outer casing protects the radar processing components, ensuring they can measure radar data normally without being damaged by trains or locomotives traveling on the railway tracks. Rubber pads provide vibration damping, preventing track vibrations from interfering with the radar processing components.
[0048] Optionally, the eddy current flaw detection sensor module is deployed on the rail head of the railway track via a U-shaped bracket. The U-shaped bracket integrates a drive motor, which is used to drive the U-shaped bracket and the eddy current flaw detection sensor module to move on the railway track.
[0049] The U-shaped bracket is slidably mounted on both sides of the rail head via a slide rail component.
[0050] Therefore, considering that railway tracks usually have a groove shape, the eddy current flaw detection sensor module can be driven to perform periodic inspections through the U-shaped bracket and drive motor, thereby realizing comprehensive detection of defects in railway tracks (such as cracks, pores, etc.).
[0051] The U-shaped bracket integrates a position encoder.
[0052] In this way, precise flaw detection of railway tracks can be achieved through position encoders and drive motors.
[0053] Optionally, high-permeability magnetic cores and coils (e.g., induction coils and excitation coils) are fixedly mounted at both ends of the U-shaped bracket.
[0054] In this way, a closed magnetic circuit can be achieved.
[0055] Optionally, the cable of the eddy current flaw detection sensor module is connected to the outside via a cable chain.
[0056] In this way, data can be collected from three dimensions: track stress, track deformation, and track defects, thus improving the comprehensiveness of railway track data.
[0057] The data processing module 12 filters and fuses the received railway track data to form a processed signal, and outputs the processed signal to the status monitoring module 13.
[0058] Optionally, the data processing module 12 can be housed inside a chassis that is dustproof and waterproof.
[0059] Therefore, considering that railway tracks are exposed outdoors, it can be concluded that the application scenario of railway track condition monitoring is subject to dust and water. Thus, by placing the data processing module 12 in a dustproof and waterproof enclosure, the data processing module 12 can be prevented from malfunctioning due to dust and water intrusion.
[0060] As one embodiment, the data processing module 12 includes a filtering module and a data fusion module. The filtering module is connected to the sensing module 11 and the data fusion module is connected to the data fusion module. The filtering module performs filtering processing on the received railway track data to form a filtered signal and outputs the filtered signal to the data fusion module. The data fusion module performs fusion processing on the received filtered signal to form a processed signal and outputs the processed signal to the status monitoring module 13.
[0061] Optionally, the filtering module can be a filtering chip, such as an FPGA (Field Programmable Gate Array) chip or an ASIC (Application Specific Integrated Circuit) chip.
[0062] Optionally, the data fusion module can be a circuit board with an integrated data fusion processing chip.
[0063] Optionally, the data fusion module is connected to the filtering module via a high-speed parallel bus.
[0064] Optionally, the data processing module 12 further includes a main control board that is connected to the filtering module and the data fusion module respectively via an inter-board connector, and the main control board is used to control the filtering module and the data fusion module.
[0065] Optionally, the data fusion module and the filtering module are plugged into the expansion slots of the main control board.
[0066] This enables the filtering module and data fusion module to connect and communicate with the main control board.
[0067] Optionally, the side of the chassis of the data processing module 12 is provided with multiple sets of waterproof aviation sockets, and each set of waterproof aviation sockets is connected to the stress sensing module, the radar deformation detection module and the eddy current flaw detection sensing module through armored cables.
[0068] The status monitoring module 13 outputs track status monitoring signals based on the received processing signals.
[0069] Optionally, the state monitoring module 13 can be a circuit board containing an FPGA chip with a pre-prepared pruned neural network model. The neural network model can be a CNN (Convolutional Neural Networks) model or other models, which are not limited here.
[0070] This allows for precise monitoring of railway track conditions.
[0071] Optionally, the status monitoring module 13 and the data processing module 12 transmit data through a PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard) interface.
[0072] Specifically, the status monitoring module 13 is connected to the main control board.
[0073] In this way, high-speed data transmission between the status monitoring module 13 and the data processing module 12 can be achieved.
[0074] In the aforementioned railway track condition monitoring device 10, the sensing module 11 detects railway track data in dimensions such as track stress distribution, track deformation, and track defects. The data processing module 12 filters and fuses the multi-dimensional railway track data to form a processed signal, thereby achieving filtering and fusion of data from various dimensions. The condition monitoring module 13 then uses the processed signal as a basis for condition monitoring, making the monitoring of the railway track determined by the joint decision of railway track data from various dimensions, thus improving the accuracy of railway track condition monitoring.
[0075] In one exemplary embodiment, such as Figure 2 As shown, the railway track condition monitoring device 10 also includes an energy module 14, which is connected to the data processing module 12 and the condition monitoring module 13 respectively, and is used to supply power to the data processing module 12 and the condition monitoring module 13. The energy module 14 includes an energy conversion module and an energy storage module, which are connected to the energy conversion module. The energy storage module is used to store the electrical energy converted by the energy conversion module.
[0076] Optionally, the energy conversion module includes at least one of a vibration energy conversion module and a thermoelectric power generation module.
[0077] As one example, the vibration energy conversion module is deployed on the track base of the railway track.
[0078] Optionally, the vibration energy conversion module is composed of multiple layers of piezoelectric ceramic sheets stacked together.
[0079] Alternatively, the multilayer piezoelectric ceramic sheet can also be encapsulated in a metal housing, which is rigidly fixed to or near the rail fasteners of the railway track.
[0080] In this way, vibration can be transmitted through the metal casing, allowing the multilayer piezoelectric ceramic sheet to absorb vibrations on the railway track.
[0081] Optionally, the thermoelectric module may include bismuth telluride (Bi2Te3) thermoelectric cells.
[0082] As one embodiment, the thermoelectric power generation module is attached to a heat-conducting substrate, with the first side of the heat-conducting substrate attached to the metal surface of the railway track and the second side of the heat-conducting substrate attached to the heat dissipation surface of the railway track.
[0083] Alternatively, the heat dissipation surface can be heat dissipation fins.
[0084] In this way, the thermoelectric power generation module can generate electricity by utilizing the temperature difference between the two sides of the heat-conducting substrate, that is, the temperature difference between the railway track and the environment in which the railway track is located.
[0085] As one embodiment, the energy module further includes a power management module, which is connected to the energy conversion module, the energy storage module, and the data processing module.
[0086] Optionally, the output wires of the energy conversion module are connected to the power management module.
[0087] In this way, the power management module can receive the power output by the power conversion module through the output wire of the power conversion module.
[0088] Optionally, the energy storage module includes multiple supercapacitor cells.
[0089] In this way, rapid charging and discharging and energy storage can be achieved, and it has the characteristics of fast charging and discharging, long cycle time, high power and high safety.
[0090] Optionally, the individual supercapacitor cells can be combined in series and / or parallel configurations.
[0091] Alternatively, multiple supercapacitor cells can be combined and packaged in a protective enclosure with temperature monitoring and pressure relief valve.
[0092] Therefore, considering that the energy storage module may experience temperature rise during the energy storage process, and that excessively high temperatures can easily lead to malfunctions of the energy storage module, multiple supercapacitor cells are combined and encapsulated in a protective box with temperature monitoring to achieve real-time temperature monitoring, thereby enabling real-time processing even at high temperatures.
[0093] Therefore, considering that high voltage may exist during the discharge process of the energy storage module, and that high voltage may cause the energy storage module to malfunction, multiple supercapacitor cells are combined and encapsulated in a protective box with a pressure relief valve to achieve voltage reduction under high voltage conditions.
[0094] Optionally, the energy storage module is fixedly installed near the data processing module.
[0095] Optionally, the energy storage module is fixedly installed on a pole on the railway track.
[0096] Optionally, the energy storage module can be connected to the power management module via a high-current connector.
[0097] As one embodiment, the power management module includes a circuit board that integrates DC (Direct Current) to DC conversion, charging management, and voltage monitoring functions.
[0098] As one embodiment, the power management module is fixedly installed inside the data processing module.
[0099] As one embodiment, the power management module is fixedly installed inside the energy protection box.
[0100] As one embodiment, the input terminal of the power management module is connected to the energy conversion module, and the output terminal of the power management module is connected to the energy storage module, the data processing module, and the status monitoring module, respectively.
[0101] As one embodiment, the power management module is used for at least one of the following: transferring the electrical energy converted by the energy conversion module to the energy storage module; transferring the electrical energy converted by the energy conversion module to the data processing module.
[0102] In this way, the energy module converts the energy that may exist on the railway track into electrical energy, thereby powering the data processing module and the condition monitoring module, and improving the energy utilization rate of the railway track condition monitoring device.
[0103] In one detailed embodiment, reference is made to Figure 3 The sensing module 11 is connected to the filtering module 121 in the data processing module 12, and the data fusion module 122 is connected to the filtering module 121; the status monitoring module 13 is connected to the data fusion module 122; the energy conversion module 141 is connected to the energy storage module 142, and the energy conversion module 141 and the energy storage module 142 are respectively connected to the power management module 143; the power management module 143 is connected to the data processing module 12.
[0104] The sensing module 11 detects at least one of the following: track stress distribution, track deformation, and track defects of the railway track, generates railway track data, and sends the railway track data to the filtering module 121 in the data processing module 12. The filtering module 121 filters the received railway track data to form a filtered signal and outputs the filtered signal to the data fusion module 122. The data fusion module 122 fuses the received filtered signal to form a processed signal and outputs the processed signal to the status monitoring module 13. The status monitoring module 13 outputs a track status monitoring signal based on the received processed signal. The energy conversion module 141 converts the collected energy into electrical energy and outputs the electrical energy to the energy storage module 142. The energy storage module 142 stores the received electrical energy. The power management module 143 controls the energy storage module 142 and the energy conversion module 141 and outputs the electrical energy stored in the energy storage module to the data processing module 12.
[0105] Thus, the sensing module 11 detects railway track data in dimensions such as track stress distribution, track deformation, and track defects. The data processing module 12 filters and fuses the multi-dimensional railway track data to form a processed signal, achieving filtering and fusion of data from various dimensions. Based on the processed signal, the condition monitoring module 13 performs condition monitoring, making the monitoring of railway tracks a decision made jointly by railway track data from various dimensions, thereby improving the accuracy of railway track condition monitoring. Furthermore, the energy module 140 converts any energy that may exist on the railway track into electrical energy, thereby powering the data processing module and the condition monitoring module, improving the energy utilization rate of the railway track condition monitoring device 10.
