[0033] To address the problem in the background art that existing rail train monitoring systems cannot perform mobile monitoring, this embodiment provides an automated monitoring device for railway transportation. This device is used for mobile image acquisition along the railway track, enabling monitoring of long-distance and large-area railway tracks. The device includes a mechanical structure and a control structure. The mechanical structure includes at least one sensor assembly 15 for acquiring images along the track, and also includes a structure enabling the sensor assembly 15 to move and rotate, thus allowing for movement of the image acquisition path and changes in the field of view. The control structure controls the mechanical structure, enabling it to change its state according to monitoring requirements.

[0034] For details on the mechanical structure of this device, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 3 The contents shown include the vehicle body and the support assembly, wherein the support assembly is mounted on the vehicle body, which serves to support and move the vehicle. The front end of the support assembly is used to mount the sensor assembly 15. The changes in the field of view of the sensor assembly 15 include changes in path movement and changes in the field of view. The changes in path movement are caused by the movement of the vehicle body, while the changes in the field of view are caused by changes in the position of the support assembly relative to the vehicle body.

[0035] Specifically, the vehicle body in this embodiment includes a platform 1 and a moving component, wherein the platform 1 is used to provide a placement platform for the support component, and the moving component is used to drive the platform 1 and the moving component to move along the path.

[0036] The moving component includes at least one active wheel set driven by a power source. The power source outputs power to the active wheel set to drive it to rotate and move, thereby further driving the platform 1 to move.

[0037] In this embodiment, to ensure the stability of the platform 1, a wheel set should be provided. This wheel set can be either a driving wheel set or a driven wheel set. When this wheel set is a driving wheel set, the corresponding moving component drives the platform 1 to move through two driving wheel sets; when this wheel set is a driven wheel set, the driven wheel set moves through one driving wheel set, thereby driving the platform 1 to move. Preferably, to ensure the synchronization of the movement of the two wheel sets and reduce control costs, in this embodiment, the moving component preferably consists of one driving wheel set and one driven wheel set.

[0038] The power source includes a rotary drive component 16 and a transmission mechanism. The rotary drive component 16 is preferably a rotary motor. The transmission mechanism includes a meshing drive gear 17 and a linkage gear 19. The drive gear 17 is located at the output end of the rotary drive component 16, and its rotation drives the linkage gear 19. The drive wheel assembly includes a drive rod 18 and drive wheels 20 located at both ends of the drive rod 18. To achieve the rotation of the drive wheels, the linkage gear 19 is fitted onto the drive rod 18, causing the drive rod 18 to rotate, which in turn drives the two drive wheels.

[0039] The rotation of the two driving wheels drives the driven wheel assembly to rotate synchronously, thereby moving the platform 1. The driven wheel assembly includes a linkage 21 and driven wheels 22 located at both ends of the linkage 21.

[0040] In this embodiment, the support assembly includes at least one adjusting arm movably mounted on the platform 1, and also includes a rotating assembly. The rotating assembly drives the adjusting arm to rotate relative to the platform 1, thereby making the angle between the adjusting arm and the platform 1 adjustable.

[0041] Preferably, to maximize the adjustment range of the adjusting arm, this embodiment uses two adjusting arms: a first adjusting arm 7 and a second adjusting arm 14. The first adjusting arm 7 is movably connected to the platform 1, and the second adjusting arm 14 is movably connected to the first adjusting arm 7. The first adjusting arm 7 can rotate once relative to the platform 1, and the second adjusting arm 14 can rotate once relative to the first adjusting arm 7. The sensor assembly 15 is located at the distal end of the second adjusting arm 14. This structural arrangement expands the field of view adjustment range of the sensor assembly 15. Correspondingly, the rotation assembly includes a first rotation assembly and a second rotation assembly. The first rotation assembly controls the rotation adjustment of the first adjusting arm 7, and the second rotation assembly controls the rotation adjustment of the second adjusting arm 14.

[0042] Furthermore, to ensure the stability of the first adjusting arm 7 and the platform 1, in this embodiment, a support base 3 is provided between the first adjusting arm 7 and the platform 1, and a support column 4 is provided on the support base 3. The first adjusting arm 7 and the support column 4 are movably arranged relative to each other.

[0043] In order to achieve the relative movable setting of the first adjusting arm 7 and the support column 4, a fixed gear 6 is fixedly installed on the side of the support column 4. The fixed gear 6 is provided with a first connecting shaft 5, which is connected to the first adjusting arm 7 to fix the first adjusting arm 7 relative to the support column 4.

[0044] In this embodiment, the first component includes a first rotation drive 9 disposed at one end of the first adjusting arm 7. The output end of the first rotation drive 9 is provided with an auxiliary gear 8, which meshes with a fixed gear 6. The rotation of the output end of the first rotation drive 9 drives the auxiliary gear 8 to rotate. Since the fixed gear 6 is rigidly connected to the support column 4, the rotation of the auxiliary gear 8 on the fixed gear 6 drives the first adjusting arm 7 to rotate synchronously, thereby realizing the rotation of the first adjusting arm 7 relative to the platform 1 and causing a change in the angle between the first adjusting arm 7 and the platform 1.

[0045] Correspondingly, an adjusting gear 10 is also provided at the other end of the first adjusting arm 7 away from the platform 1, wherein the adjusting gear 10 is also rigidly connected to the first adjusting arm 7. The second rotating assembly includes a second rotating drive 13 mounted on the second adjusting arm 14, and a rotating gear 12 is provided at the output end of the second rotating drive 13. The rotating gear 12 meshes with the adjusting gear 10 of the first adjusting arm 7. The second adjusting arm 14 is movable relative to the first adjusting arm 7 by passing the adjusting gear 10 through the second connecting shaft 11. The second adjusting arm 14 can rotate synchronously relative to the first adjusting arm 7 by rotating the motor along the adjusting gear 10.

[0046] In this embodiment, the first adjusting arm 7 and the second adjusting arm 14 can rotate independently. When the first adjusting arm 7 rotates independently, it drives the second adjusting arm 14 to rotate, thereby driving the sensor assembly 15 to rotate accordingly. When the second adjusting arm 14 rotates independently, the first adjusting arm 7 is stationary, and the sensor assembly 15 is driven to rotate accordingly through the second adjusting arm 14. When the first adjusting arm 7 and the second adjusting arm 14 rotate simultaneously, the rotation range of the sensor assembly 15 is maximized.

[0047] The above structure refers to the mechanical structure of the device, while in this embodiment, the control part is the central control unit, see reference. Figure 4 and Figure 5 This central control unit is a localized control unit and is mounted on the platform 1 via the housing 2.

[0048] Specifically, the central control unit is electrically connected to the power source, rotating component, and sensor component 15 in the mechanical structure, and is used to control the power output and state changes of the power source and rotating component, as well as to receive image information.

[0049] The central control unit includes a central processing module 25, a data storage module 26, a wireless transceiver module 24, and a logic encoding module 23. The central processing module 25 establishes bidirectional communication with both the data storage module 26 and the wireless transceiver module 24. The logic encoding module 23 acquires the image information and transmits it to the central processing module 25. The central processing module 25 is also electrically connected to the power source and rotating components in the mechanical structure.

[0050] Specifically, the central processing module 25 is electrically connected to the rotary drive component 16, the first rotary drive component 9, and the second rotary component to realize the control of the power source and the rotary components.

[0051] The image information acquired by the sensor component 15 is transmitted to the logic encoding module 23, which then sends it to the central processing module 25. The data storage module 26 stores the data collected by the camera, the wireless transceiver module 24 transmits the data, and the central processing module 25 controls the drive of the third rotating drive component 16. This enables the automated monitoring device to conveniently acquire and transmit images, facilitating the storage and transmission of the acquired images.

[0052] In this embodiment, an image acquisition device and two input channels are included. The image acquisition device comprises a beam splitter and a sensor. The beam splitter splits the incident light beam into two beams of different wavelengths, which enter the sensor through corresponding input channels. The split beams include a visible light beam and an ultraviolet light beam. The sensor assembly 15 forms a visual reference by superimposing the visible light and solar-blind ultraviolet light channels to locate the target position. Finally, a video signal is output, which can switch between three video display modes: solar-blind ultraviolet, visible light, and fused video.

[0053] In some other embodiments, an infrared sensor may also be provided in this sensor assembly 15 to ensure the comprehensiveness of the acquired image information.

[0054] In other embodiments, the infrared thermal image distribution of different parts of the target object in reality lacks depth and three-dimensionality compared to visible light due to the very weak signal. Therefore, in actual operation, to more effectively determine the infrared thermal field of the target object, auxiliary measures are often used to enhance the instrument's practical functions, such as controlling image brightness and contrast, actual calibration, and performing pseudo-color depiction, contour line and histogram calculations. Many fault modes of power equipment in overhead lines and substations manifest as abnormal thermal states. The basic principle of infrared detection is to obtain the thermal state characteristics of the equipment by detecting its infrared radiation signal, and then, based on this thermal state and appropriate criteria, determine whether the equipment is in a normal state.

[0055] The automated monitoring device provided in this embodiment not only enables mobile image acquisition and monitoring of railway transportation facilities, facilitating timely detection of equipment overheating, discharge, and line, bridge, and tunnel defects, and increasing the acquisition range of the automated monitoring device, but also improves the convenience of monitoring on railways.

[0056] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
