DETAILED DESCRIPTION

[0032] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0033] As shown in the drawings, the embodiments of the present application provide a detection system, comprising: Figs. 1-3

[0034] The top support 100 is provided with a first image acquisition assembly;

[0035] The side support 102 is provided with a roller 104 at the bottom and is located below the top support 100, and a second image acquisition assembly is installed on the side support 102;

[0036] The bottom support 106 is located on one side of the side support 102 and is provided with a third image acquisition assembly;

[0037] The top support 100, the side support 102 and the bottom support 106 form an image acquisition space, and the first image acquisition assembly, the second image acquisition assembly and the third image acquisition assembly are used to acquire the image of the rail vehicle when the rail vehicle is located in the image acquisition space.

[0038] ​According to the detection system provided in the embodiment of the utility model, through the first image acquisition assembly, the second image acquisition assembly and the third image acquisition assembly respectively installed on the top support 100, the side support 102 and the bottom support 106, the detection system can realize the image acquisition of the rail vehicle in all directions. This multi-angle and multi-position acquisition mode can ensure the detailed and comprehensive inspection of the rail vehicle, and improve the detection efficiency and accuracy. The bottom of the side support 102 is provided with the roller 104, which makes the whole detection system can be easily moved and adjusted at different positions to adapt to different environments and detection requirements. The design of the roller 104 also facilitates the rapid deployment and disassembly of the detection system, and improves the use convenience. The top support 100, the side support 102 and the bottom support 106 jointly enclose to form a relatively closed image acquisition space, which is helpful for better focusing and capturing the image information of the rail vehicle. At the same time, this structured design also enhances the stability and reliability of the system. In addition, the image data collected from different angles by multiple image acquisition assemblies can be complementary and compared, so as to more accurately identify and judge the state and problems of the rail vehicle. The detection system can add more image acquisition assemblies or adjust the position and angle of the existing assemblies according to the needs, to adapt to the detection requirements of different types and specifications of rail vehicles. This modular and expandable design makes the detection system have stronger adaptability and universality.

[0039] Please continue to see Figs. 1-3 In the embodiment of the utility model, the detection system mainly consists of three parts of the top support 100, the side support 102 and the bottom support 106, and each support is provided with a corresponding image acquisition assembly, which cooperates to realize the comprehensive detection of the rail vehicle.

[0040] The top support 100 is located at the uppermost of the whole detection system, and the first image acquisition assembly is installed thereon. The first image acquisition assembly is mainly used for collecting the images of the top and upper part of the rail vehicle, including the roof, the window, the antenna and other parts.

[0041] The side support 102 is located below the top support 100, and the roller 104 is arranged at the bottom of the side support 102, which facilitates the movement and positioning of the whole detection system. The second image acquisition assembly is installed on the side support 102, and is mainly used for collecting the images of the side of the rail vehicle, including the running part, the body, the door, the wheel and other parts.

[0042] The bottom support 106 is located on one side of the side support 102, and the third image acquisition assembly is installed thereon. The third image acquisition assembly is mainly used for collecting the images of the bottom and lower part of the rail vehicle, including the bottom of the vehicle, the suspension system and other key parts.

[0043] The image acquisition space is formed by the surrounding of the top support 100, the side support 102 and the bottom support 106. When the rail vehicle enters this space, the three groups of image acquisition components will start simultaneously to conduct all-around image acquisition of the vehicle from multiple angles.

[0044] In addition, each image acquisition component can be independently controlled, and the shooting angle, focal length and other parameters can be adjusted as needed to obtain the clearest and most accurate image information. At the same time, these image data can also be transmitted to the background system in real time for analysis and processing, further improving the detection efficiency and accuracy.

[0045] The detection system also has high automation and intelligence. The above-mentioned groups of image acquisition components can automatically start and stop, automatically adjust the shooting parameters, and automatically transmit the image data. The background system can also automatically analyze and process the image data to generate detection reports and warning information, greatly reducing the burden of manual operation and improving the detection efficiency and accuracy.

[0046] According to an embodiment of the present application, the first image acquisition component includes a first two-dimensional image acquisition piece 108 and a first three-dimensional image acquisition piece 110, and the first two-dimensional image acquisition piece 108 and the first three-dimensional image acquisition piece 110 are movably installed on the top support 100.

[0047] In the embodiment of the present application, the first two-dimensional image acquisition piece 108 is mainly used to capture two-dimensional image information of the top of the rail vehicle, such as the state of the vehicle body surface, the integrity of the window, etc. This acquisition piece can produce a plane image with very high definition, which is convenient for detailed inspection of the appearance of the vehicle.

[0048] In addition, the first three-dimensional image acquisition piece 110 can be two, and the two first three-dimensional image acquisition pieces 110 can be installed on the top support 100 at intervals.

[0049] The first three-dimensional image acquisition piece 110 can acquire three-dimensional image data of the top of the vehicle. Three-dimensional images not only can show the appearance of an object, but also can provide information about the shape, structure and depth of the object. This is very helpful for detecting small depressions, protrusions or other irregular shapes on the surface of the vehicle. In addition, three-dimensional images can also be used to construct a three-dimensional model of the vehicle, providing a more abundant data basis for subsequent analysis and processing.

[0050] By introducing the first three-dimensional image acquisition piece 110, the detection system can not only acquire two-dimensional image information of the top of the rail vehicle, but also acquire more detailed and comprehensive three-dimensional image data. This makes the detection system more accurately identify the small defects and structural changes on the surface of the vehicle, improving the accuracy and reliability of the detection.

[0051] Meanwhile, since the first two-dimensional image acquisition device 108 and the first three-dimensional image acquisition device 110 are movably installed on the top bracket 100, the detection system can be more flexible to adapt to different detection requirements and environmental conditions. Whether indoors or outdoors, whether for large or small rail vehicles, the detection system can provide high-quality image data to provide strong support for subsequent analysis and processing.

[0052] According to an embodiment of the present application, the top bracket 100 comprises:

[0053] The mounting beam 112 is used to be installed at the mounting position.

[0054] The overhanging beam is movably installed on the mounting beam 112, and the first two-dimensional image acquisition device 108 and the first three-dimensional image acquisition device 110 are movably installed on the overhanging beam.

[0055] In the embodiment of the present application, the mounting beam 112 is the main part of the top bracket 100, which is used to be stably installed at a specific mounting position. The mounting position can be a roof, a gantry, etc. The mounting beam 112 has sufficient strength and rigidity to ensure stability during detection and is not affected by external interference.

[0056] The overhanging beam is movably installed on the mounting beam 112, and the first two-dimensional image acquisition device 108 and the first three-dimensional image acquisition device 110 are movably installed on the overhanging beam.

[0057] Through the combination of the mounting beam 112 and the overhanging beam, the entire bracket structure is more stable and reliable, which can ensure stability during detection and is not affected by vibration or displacement. The movability of the overhanging beam allows the acquisition device to flexibly adjust the position and angle to adapt to the size and shape of different rail vehicles, ensuring the accuracy and integrity of image acquisition. This design also improves the operation convenience of the detection system, allowing the operator to easily install, adjust and replace the acquisition device.

[0058] The first two-dimensional image acquisition device 108 and the first three-dimensional image acquisition device 110 are the key components movably installed on the overhanging beam. Through fine tuning, translation, rotation or inclination, etc., it can be ensured that the first two-dimensional image acquisition device 108 and the first three-dimensional image acquisition device 110 can accurately aim at the target area and capture high-quality image data.

[0059] According to an embodiment of the present application, the second image acquisition assembly includes a second two-dimensional image acquisition component 116 and a second three-dimensional image acquisition component 118. The second two-dimensional image acquisition component 116 and the second three-dimensional image acquisition component 118 are movably installed on the side support 102.

[0060] In the embodiment of the present application, the second two-dimensional image acquisition component 116 is mainly used to capture two-dimensional image information of the side of the rail vehicle. This acquisition component can generate high-definition planar images, which can clearly show the appearance, details and possible problems of the side of the vehicle. It is very helpful for detecting the integrity of the vehicle body, the state of the vehicle window and the working condition of the vehicle door and other components.

[0061] Among them, the second two-dimensional image acquisition component 116 can be provided in multiple, and the multiple second two-dimensional image acquisition components 116 are arranged in the height direction of the side support 102.

[0062] The second three-dimensional image acquisition component 118 further expands the dimension of image acquisition. It can acquire three-dimensional image data of the side of the rail vehicle, and provide more comprehensive and in-depth detection information. The three-dimensional image not only shows the appearance of the object, but also reveals the shape, structure and depth information of the object. This enables the detection system to more accurately identify the small concave, convex or other irregular shapes on the side of the vehicle, further improving the accuracy and reliability of the detection.

[0063] The second two-dimensional image acquisition component 116 and the second three-dimensional image acquisition component 118 are movably installed on the side support 102. The side support 102 has sufficient stability and flexibility, and can support the second two-dimensional image acquisition component 116 and the second three-dimensional image acquisition component 118 and allow them to be adjusted as needed. By adjusting the position and angle of the second two-dimensional image acquisition component 116 and the second three-dimensional image acquisition component 118, it can be ensured that they can accurately align with the side of the rail vehicle and capture the best image data.

[0064] By introducing the second three-dimensional image acquisition component 118 and movably installing it on the side support 102, the function and performance of the second image acquisition assembly are significantly enhanced. By simultaneously acquiring two-dimensional and three-dimensional image data, the detection system can more comprehensively understand the situation of the side of the rail vehicle, including appearance details, structural changes and possible defects. This helps to improve the accuracy and reliability of the detection, and reduces the possibility of missed detection or false detection.

[0065] According to an embodiment of the present application, it further includes a speed measurement radar 120 and a vehicle number recognition component 122, and the speed measurement radar 120 and the vehicle number recognition component 122 are installed on the side support 102.

[0066] In the embodiment of the utility model, the speed radar 120 is installed on the side support 102, so as to accurately measure the speed of the rail vehicle when it passes. This design enables the detection system to obtain the speed information of the rail vehicle in real time, providing an important basis for subsequent data analysis and processing.

[0067] By measuring the speed of the rail vehicle in real time, the detection system can more accurately evaluate the running state of the vehicle and timely discover abnormal conditions such as overspeed.

[0068] The vehicle number recognition device 122 is a device capable of automatically recognizing the vehicle number. It usually adopts image processing technology, captures, recognizes and analyzes the vehicle number on the vehicle, and thus obtains the identity information of the vehicle. In the utility model, the vehicle number recognition device 122 is also installed on the side support 102, so as to automatically capture and recognize the vehicle number of the rail vehicle during the detection process. This function not only improves the detection efficiency, but also reduces the possibility of manual input errors.

[0069] The function of automatically recognizing the vehicle number enables the detection system to automatically record the identity information of each detected vehicle, providing convenience for subsequent data management and tracing.

[0070] By integrating the speed radar 120 and the vehicle number recognition device 122 on the side support 102, the detection system can realize synchronous detection and recognition of the speed and vehicle number of the rail vehicle. This design not only improves the automation level of the detection system, but also makes the entire detection process more efficient, accurate and reliable.

[0071] According to one embodiment of the utility model, the side support 102 comprises:

[0072] The base 124, on which the roller 104 is installed;

[0073] The vertical beam 126, which is installed on the base 124, and the second two-dimensional image acquisition device 116, the second three-dimensional image acquisition device 118, the speed radar 120 and the vehicle number recognition device 122 are movably installed on the vertical beam 126;

[0074] The support beam 128, which is hinged between the vertical beam 126 and the base 124.

[0075] In the embodiment of the utility model, the side support 102 mainly comprises the base 124, the vertical beam 126 and the support beam 128, which makes the side support 102 not only stable and reliable, but also functional and capable of adapting to various detection requirements.

[0076] The base 124 is the base part of the side bracket 102, which bears the weight of the entire side bracket 102 and ensures the stability and safety of the side bracket 102. The rollers 104 are installed on the lower part of the base 124, which makes the entire detection system convenient to move and position, adapting to different detection environments and needs.

[0077] The vertical beam 126 is the main structure of the side bracket 102, which is installed on the base 124 and provides a solid support for the second image acquisition assembly. The height and position of the vertical beam 126 can be adjusted as needed to ensure that the second image acquisition assembly, the speed radar 120 and the vehicle number recognition device 122 can accurately align the target area.

[0078] The support beam 128 is hinged between the vertical beam 126 and the base 124, forming a movable connection structure. This design allows the support beam 128 to adjust the angle and position within a certain range, further enhancing the flexibility and adaptability of the side bracket 102.

[0079] The second two-dimensional image acquisition device 116, the second three-dimensional image acquisition device 118, the speed radar 120 and the vehicle number recognition device 122 are movably installed on the vertical beam 126. By doing so, the second two-dimensional image acquisition device 116, the second three-dimensional image acquisition device 118, the speed radar 120 and the vehicle number recognition device 122 can be fine-tuned on the vertical beam 126 to achieve accurate detection of different rail vehicles.

[0080] According to an embodiment of the present application, the side bracket 102 is two groups, and the two groups of side brackets 102 are symmetrically arranged with the center of the top bracket 100 or the bottom bracket 106 as the symmetry axis.

[0081] In the embodiment of the present application, the symmetric design of the side bracket 102 allows the detection system to simultaneously perform image acquisition and other related detection from both sides of the rail vehicle during operation. Each group of side brackets 102 is equipped with corresponding key components such as the second image acquisition assembly, the speed radar 120 and the vehicle number recognition device 122, ensuring the comprehensiveness and accuracy of the detection.

[0082] With the center of the top bracket 100 or the bottom bracket 106 as the symmetry axis, the two groups of side brackets 102 are mirror-symmetric, which not only improves the working efficiency of the detection system, but also ensures the consistency and reliability of the detection data. No matter which direction the rail vehicle passes through, the detection system can quickly and accurately capture the side information of the vehicle and perform corresponding analysis and processing.

[0083] In addition, the symmetrically arranged side supports 102 also help to improve the stability and safety of the detection system. Since the two groups of supports have the same structure and configuration, they are more convenient to install, debug and maintain. At the same time, this design also reduces errors and failures that may be caused by structural differences between the supports, improving the overall performance of the detection system.

[0084] According to an embodiment of the present application, it further comprises a light supplementing member 130, which is installed on one side of the vertical beam 126 facing the bottom support 106.

[0085] In the embodiment of the present application, the light supplementing member 130 is installed on one side of the vertical beam 126 facing the bottom support 106, i.e. near the second two-dimensional image acquisition member 116, the second three-dimensional image acquisition member 118, the speed measurement radar 120 and the vehicle number recognition member 122. This design allows the light supplementing member 130 to directly illuminate the side of the vehicle being detected, effectively eliminating shadows and dark areas, and improving the clarity and contrast of image acquisition.

[0086] The specific type and specifications of the light supplementing member 130 can be selected according to actual needs. For example, LED light supplementing lamps, halogen light supplementing lamps or other suitable light sources can be used. At the same time, the brightness and illumination angle of the light supplementing member 130 can also be adjusted to adapt to the needs of different detection environments and vehicle types.

[0087] By adding the light supplementing member 130, the detection system can maintain stable image acquisition quality in environments with insufficient light or large changes in light. Whether it is at night, on rainy days or other conditions with relatively dark light, the light supplementing member 130 can provide sufficient light support for image acquisition, ensuring that the images collected are clear and accurate.

[0088] According to an embodiment of the present application, the vertical beam 126 comprises a plurality of vertical segments, which are inserted into each other to adjust the height of the vertical beam 126.

[0089] In the embodiment of the present application, the design of the vertical segments allows the vertical beam 126 to be adjusted in height according to actual needs. Each vertical segment has a standard size and interface, ensuring that they can be tightly inserted into each other to form a stable support structure. By increasing or decreasing the number of vertical segments, the height of the vertical beam 126 can be flexibly adjusted to adapt to different detection scenarios and vehicle height requirements.

[0090] This design not only improves the adaptability of the detection system, but also simplifies the adjustment process. The operator can easily add or remove vertical segments as needed to quickly adjust the height of the vertical beam 126. This flexibility allows the detection system to adapt to a wider variety of rail vehicles, improving its practicality and work efficiency.

[0091] At the same time, the vertical segmented plug-in connection mode also ensures the stability and safety of the vertical beam 126. The plug-in interface is carefully designed to ensure the tight connection between the vertical segments, preventing loosening or falling off during detection. In addition, the vertical segments are also made of high-strength materials, which can withstand large weight and impact force, ensuring the stable operation of the detection system.

[0092] According to an embodiment of the present application, the third image acquisition assembly includes a third two-dimensional image acquisition component 132 and a third three-dimensional image acquisition component 134. The third two-dimensional image acquisition component 132 and the third three-dimensional image acquisition component 134 are movably mounted on the bottom bracket 106.

[0093] In the embodiment of the present application, the third two-dimensional image acquisition component 132 is mainly used to capture two-dimensional image information of the bottom of the rail vehicle. The third two-dimensional image acquisition component 132 can provide high-definition planar images, helping the detection personnel to observe the structure, details and possible problems of the vehicle bottom in detail. It is very helpful for detecting the integrity of the vehicle bottom, the installation of components and potential damage.

[0094] The third three-dimensional image acquisition component 134 further expands the dimension of image acquisition. The third three-dimensional image acquisition component 134 can acquire three-dimensional image data of the bottom of the rail vehicle, providing more in-depth information for detection. Three-dimensional images not only show the appearance of objects, but also reveal their shape, structure and depth information, so that the detection system can more accurately identify the tiny defects, abnormal protrusions or other irregular shapes on the bottom.

[0095] The third two-dimensional image acquisition component 132 and the third three-dimensional image acquisition component 134 are both set to be movably mounted, which means they can be adjusted as needed to adapt to the bottom structure of different rail vehicles and detection requirements. The bottom bracket 106 provides stable support for them and allows the third two-dimensional image acquisition component 132 and the third three-dimensional image acquisition component 134 to adjust their position, angle or height if necessary.

[0096] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
