[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art in this application. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. It should be understood that, unless otherwise specified, "plurality" in this application means two or more than two. In addition, unless explicitly denied, the technical features of one embodiment may be beneficially combined with one or more other embodiments.
[0050] Please refer to Figure 1 , is a schematic diagram of an application scenario of the detection system of an embodiment of the present application. The detection system 1 can be set up in a place where vehicles frequently enter and exit, such as Figure 1Gas station 2 in the embodiment is a single-lane gas station. Detection system 1 may be the detection system 1 of the first, second, third, fourth, and fifth embodiments described below. In this embodiment, detection system 1 is installed at the entrance of gas station 2 or at the entrance of each single lane of gas station 2. It is understood that detection system 1 may also be installed in other locations where vehicles frequently enter and exit, such as charging stations and parking lots. Before entering gas station 2 to refuel, a vehicle will first pass through detection system 1 installed in a single lane. Detection system 1 can capture images of the vehicle's underbody, including images of the vehicle's chassis and tires, and determine whether the vehicle's underbody condition is abnormal based on the underbody images. In some embodiments, a detection report can be generated based on whether the vehicle's underbody condition is abnormal after refueling. Consequently, a vehicle detection report can be provided to the driver after refueling, increasing the frequency of vehicle underbody condition detection and reducing underbody condition detection time. This allows the driver to promptly be informed of any abnormalities under the vehicle, thus avoiding safety hazards.
[0051] See also Figure 2 and Figure 3 , Figure 2 and Figure 3This is a structural schematic diagram of the detection system of the first embodiment of the present application. The detection system 1 includes a bottom acquisition module 10 and a processing module 20. The bottom acquisition module 10 and the processing module 20 can be connected by a wired connection, for example, a communication link is established through a data cable, or by a wireless communication connection, for example, a wireless communication connection is established through a Bluetooth connection or a wireless LAN connection. The bottom acquisition module 10 is used to collect the bottom image of the vehicle toward the bottom of the vehicle. Specifically, the bottom acquisition module 10 is set on the road. Roads not only refer to highways, urban roads, and rural roads, but also include passages in places where vehicles can travel, such as the passages of the aforementioned gas station 2. The number of bottom acquisition modules 10 can be multiple, and multiple bottom acquisition modules 10 are arranged in sequence along the direction of vehicle travel. The bottom acquisition module 10 includes a first signal receiving end (not shown) (the first signal receiving end can be a lens). The first signal receiving end can be set on the bottom acquisition module 10 perpendicular to the road surface. When the vehicle travels on the bottom acquisition module 10, the first signal receiving end can receive signals emitted or reflected from the bottom of the vehicle. The first signal receiving end can also be set on the bottom acquisition module 10 with an adjustable angle. When the vehicle approaches and is within a first preset distance range from the bottom acquisition module 10, the first signal receiving end can receive the signal emitted or reflected from the bottom of the vehicle. It is understandable that the angles of the first signal receiving ends of multiple bottom acquisition modules 10 can be adjusted according to the positions of the parts that need to be collected in the bottom of the vehicle to collect the images of the parts. The bottom acquisition module 10 includes a light-sensitive camera (the light-sensitive camera is provided with a light-sensitive sensor and uses the optical imaging principle) or an infrared camera (the infrared camera is provided with an infrared sensor and uses the infrared imaging principle), etc. It is understandable that after the signal emitted or reflected from the bottom of the vehicle enters the bottom acquisition module 10, the bottom acquisition module 10 generates an image of the bottom of the vehicle based on the signal. The image of the bottom of the vehicle includes tire images and chassis images, etc.
[0052] The processing module 20 can be located on the road or on a remote server. The processing module 20 includes hardware such as a memory and a control chip. The processing module 20 is used to determine whether the vehicle's underbody condition is abnormal based on the vehicle underbody image. Specifically, after receiving one or more vehicle underbody images from the underbody acquisition module 10, the processing module 20 determines whether the vehicle's underbody condition is abnormal based on the one or more vehicle underbody images. For example, the processing module 20 compares each vehicle underbody image with a corresponding preset vehicle underbody image to determine whether they are consistent. If they are consistent, the vehicle's underbody condition is determined to be normal; if they are inconsistent, the vehicle's underbody condition is determined to be abnormal. Alternatively, the multiple vehicle underbody images can form a partial or complete vehicle underbody model. For example, a tire model can be formed based on the tire image, and a chassis model can be formed based on the chassis image. The vehicle underbody model is compared with the preset vehicle underbody model to determine whether they are consistent. If they are consistent, the vehicle's underbody condition is determined to be normal; if they are inconsistent, the vehicle's underbody condition is determined to be abnormal. For example, the processing module 20 can identify a foreign object inserted into the tire based on the tire image and determine that the tire is abnormal. The processing module 20 identifies chassis oil leakage based on the chassis image and determines that the chassis is abnormal.
[0053] As can be understood, when a vehicle passes underbody acquisition module 10, signals emitted or reflected from the vehicle's underbody enter the module. As the vehicle moves, the first signal receiving end of the module receives different signals and generates different vehicle underbody images based on these signals. Alternatively, the vehicle can remain stationary above the module, which can then be moved at an adjustable angle to receive different signals from the vehicle's underbody and generate different vehicle underbody images based on these signals. The processing module 20 determines whether the vehicle's underbody condition is abnormal based on these different vehicle underbody images.
[0054] In this way, when a vehicle passes under the vehicle, the underbody acquisition module 10, which faces the vehicle's bottom, captures an image of the vehicle's bottom. The processing module 20 then determines the vehicle's bottom condition based on the image. This increases the frequency of vehicle bottom condition detection, reduces detection time, and allows the driver to promptly identify any abnormalities under the vehicle, thus avoiding safety hazards.
[0055] Please refer to Figure 2 and Figure 3 The detection system 1 further includes a start trigger module 30 and an end trigger module 40. The start trigger module 30 and the end trigger module 40 are respectively connected to the bottom acquisition module 10 by wired or wireless communication. The start trigger module 30 is configured to generate a first trigger signal when it senses a vehicle approaching the bottom acquisition module 10. The end trigger module 40 is configured to generate a second trigger signal when it senses a vehicle moving away from the bottom acquisition module 10. Both the start trigger module 30 and the end trigger module 40 can be pressure sensors, infrared detectors, cameras, etc.
[0056] In one embodiment, the bottom acquisition module 10 has an end (i.e., the first end) that the vehicle approaches, and an end (i.e., the second end) that the vehicle moves away from. The start trigger module 30 is arranged on the road where the vehicle is close to the first end, and the end trigger module 40 is arranged on the road where the vehicle is away from the second end. The start trigger module 30 and the end trigger module 40 both include a second signal receiving end (not shown) (the second signal receiving end can be a lens). The second signal receiving end can be arranged on the start trigger module 30 or the end trigger module 40 perpendicular to the road surface. When the vehicle travels on the start trigger module 30 or the end trigger module 40, the start trigger module 30 or the end trigger module 40 can sense the signal emitted or reflected from the bottom of the vehicle. The second signal receiving end can also form a first preset angle with the road surface and be arranged on the start trigger module 30 or the end trigger module 40. The first preset angle is less than 90°. When a vehicle approaches and is within a second distance from the start trigger module 30 or the end trigger module 40, the start trigger module 30 or the end trigger module 40 can sense a signal emitted or reflected from the bottom of the vehicle. In another embodiment, the start trigger module 30a is positioned on road infrastructure or beside the road at a third distance from the first end, and faces the road surface near the first end of the vehicle, which may be a point on the road surface at a fourth distance from the first end. The end trigger module 40a is positioned on road infrastructure or beside the road at a third distance from the second end, and faces the road surface far from the second end of the vehicle, which may be a point on the road surface at a fourth distance from the second end.
[0057] It will be understood that when the start trigger module 30 or the end trigger module 40 is a sensing element such as an infrared detector, the second distance range and the fourth distance range are the sensing range of the start trigger module 30 or the end trigger module 40. When the vehicle enters the sensing range of the start trigger module 30 while driving, the start trigger module 30 generates a first trigger signal. When the start trigger module 30 is a pressure sensor, when the vehicle travels in the direction of travel and passes over the start trigger module 30, the pressure received by the start trigger module 30 reaches a preset pressure threshold, generating a first trigger signal. In response to the first trigger signal, the underbody acquisition module 10 captures an image of the vehicle's underbody. It will be understood that by providing the start trigger module 30, it can be sensed in a timely manner that the vehicle is about to enter the underbody acquisition module 10, allowing the underbody acquisition module 10 to capture an image of the vehicle's underbody in a timely manner. When the vehicle moves away from the underbody acquisition module 10 and enters the sensing range of the end trigger module 40, the end trigger module 40 generates a second trigger signal. If the end trigger module 40 is a pressure sensor, when the vehicle approaches the end trigger module 40 and the pressure received by the end trigger module 40 reaches a preset pressure threshold, the end trigger module 40 generates a second trigger signal. In response to the second trigger signal, the underbody acquisition module 10 ceases capturing images of the vehicle's underbody. It can be appreciated that by providing the end trigger module 40, it is possible to promptly sense when the vehicle is about to leave the underbody acquisition module 10, allowing the underbody acquisition module 10 to promptly terminate capturing images of the vehicle's underbody.
[0058] See also Figure 4 , Figure 4This is a structural diagram of the detection system of the second embodiment of the present application. Compared with the first embodiment, the second embodiment also includes a detection platform 50, which is located on the road. The bottom collection module 10, the start trigger module 30 and the end trigger module 40 are all arranged on the detection platform 50. The detection platform 50 includes a first area 51 and two second areas 52. The first area 51 is located between the two second areas 52. The bottom collection module 10 is arranged in the first area 51, and the second area 52 is used to support the wheels on both sides of the vehicle. The first area 51 includes a first groove 511, and the second area 52 includes a first protrusion 521. Specifically, the detection platform 50 is provided with two first protrusions 521 along the driving direction of the wheels on both sides, and the support surfaces of the two first protrusions 521 are flush, so that the vehicle can smoothly pass through the detection platform 50. The depression between the two first protrusions 521 forms a first groove 511. Multiple bottom collection modules 10 are sequentially arranged within the first groove 511 along the vehicle's travel direction. Signals reflected or emitted from the bottom of the vehicle are incident upon the first signal receiving end of the bottom collection module 10 through the top of the first groove 511. The first area 51 may also include a first cover plate 512. The first cover plate 512 is disposed on the first groove 511 and movably connected to one side of the first groove 511 to prevent other objects from entering the first groove 511. The surface of the first cover plate 512 facing away from the first groove 511 may be flush with the supporting surfaces of the two first protrusions 521. The first cover plate 512 may be transparent or opaque. The transparent cover plate 512 may be made of tempered glass. The opaque first cover plate 512, opposite the first signal receiving end, has a through hole, which is provided with a transparent member made of a material such as tempered glass. The first signal receiving end receives the signal from the bottom of the vehicle through the through hole or the transparent first cover plate 512 .
[0059] The detection platform 50 may also include a driving assist component 53, one end of the driving assist component 53 is connected to the second area 52, and the other end of the driving assist component 53 is in contact with the road surface, so that the wheel enters or moves away from the second area 52 from the road surface through the driving assist component 53. In one embodiment, the driving assist component 53 includes an entrance assist component 531 and an exit assist component 532, one end of the entrance assist component 531 is fixedly connected or detachably connected to the end of the second area 52 close to the vehicle (i.e., the third end), and the other end is in contact with the road surface. The exit assist component 532 is fixedly connected or detachably connected to the end of the second area 52 away from the vehicle (i.e., the fourth end). In one embodiment, the entrance assist component 531 and the exit assist component 532 are both roughly a slope, one side of the slope is connected to the second area 52, and the other side is in contact with the road surface. The slope is fixedly connected or detachably connected to the second area 52. In another embodiment, both the inlet auxiliary member 531 and the outlet auxiliary member 532 are plates, one end of the plate is fixedly or detachably connected to the second area 52 , and the other end is in contact with the road surface.
[0060] It can be understood that by providing the entrance auxiliary member 531, the vehicle can smoothly enter the second area 52 from the road surface. By providing the exit auxiliary member 532, the vehicle can smoothly exit the second area 52 and enter the road surface.
[0061] The start trigger module 30 may also be disposed on or embedded within the entrance auxiliary member 531, so that when a vehicle passes through the entrance auxiliary member 531, the start trigger module 30 can receive a pressure or sensing signal to generate a first trigger signal. The end trigger module 40 may also be disposed on or embedded within the exit auxiliary member 532, so that when a vehicle passes through the exit auxiliary member 532, the start trigger module 30 can receive a pressure or sensing signal to generate a second trigger signal.
[0062] The third end of the second area 52 may also be provided with a wheel assist member 54, which is used to guide wheels into the second area 52. In one embodiment, the third end, closest to the first area 51 (i.e., the first end), is fixedly or detachably connected to the wheel assist member 54. The wheel assist member 54 forms a second predetermined angle with the end of the first area 51 where the vehicle approaches. The second predetermined angle is less than 90°, increasing the area of the entry point for wheels to enter the second area 52 and reducing the area of the entry point for vehicles to enter the first area 51, thereby making it easier for wheels to enter the second area 52. The wheel assist member 54 may be roughly trapezoidal, rectangular, or other strip-like shape. For example, the trapezoidal shape has one end of its upper base connected to the first end, and its lower base suspended above the entry assist member 531.
[0063] The detection system 1 may also include a side acquisition module 60, which is arranged on both sides of the detection platform 50 and is used to collect the bottom image of the vehicle toward the side of the vehicle. Specifically, the difference between the side acquisition module 60 and the bottom acquisition module 10 is that the side acquisition module 60 collects the bottom image of the vehicle from the side of the vehicle. The side acquisition module 60 is provided with a signal receiving end (i.e., a third signal receiving end), and the third signal receiving end can be fixedly or angle-adjustably arranged on the side acquisition module 60. The height of the side acquisition module 60 is roughly flush with the top of the wheel of the vehicle, so that the third signal receiving end can collect the wheel image of the entire wheel. In each set of side-by-side wheels, each vehicle has a side facing the other wheel (i.e., the second side), and another side away from the other wheel (i.e., the third side). There can be multiple side acquisition modules 60, each of which is disposed on both sides of the inspection platform 50. Specifically, the side acquisition modules 60 are divided into two groups. Each group of side acquisition modules 60 can be disposed on both ends of the second area 52 of the inspection platform 50, facing the ground, and outside the inspection platform 50 to capture images of the four wheels of the vehicle. It can be understood that compared to the bottom acquisition module 10, the side acquisition modules 60 can capture images of the third side of more wheels.
[0064] In one application scenario, a vehicle enters the entry assist component 531 and presses over the activation trigger module 30. When the pressure received by the activation trigger module 30 exceeds a preset pressure, a first trigger signal is generated. In response to the first trigger signal, the bottom acquisition modules 10a and 10b, as well as the side acquisition modules 60a, 60b, 60c, and 60d in the first area 51, adjust their angles to capture images of the vehicle's bottom surface as the vehicle moves. For example, after the vehicle enters the second area 52 with the assistance of the wheel assist component 54, when the vehicle is in the first position (i.e., the front wheels are approximately located at both ends of the side acquisition module 60a), the side acquisition modules 60a and 60d, in addition to capturing the front tread of the front wheels as with the bottom acquisition module 10b, also capture tread images and wheel spoke images of the third front side of the front wheels. The side acquisition modules 60b and 60c capture the entire tread and wheel spoke images of the third side of the front wheels. The bottom acquisition module 10a captures images of the front section of the vehicle's chassis and the tread and spoke images of the second side of the front wheels. When the vehicle is in the second position (i.e., the rear wheels are roughly located at both ends of the side acquisition module 60a), the bottom acquisition module 10b captures images of the front section of the vehicle's chassis and the tread and spoke images of the second side of the front wheels. The side acquisition modules 60a and 60d capture images of the entire tread and spoke images of the third side of the front wheels. The bottom acquisition module 10a captures images of the rear section of the vehicle's chassis and the tread and spoke images of the second side of the rear wheels. The side acquisition modules 60b and 60c capture images of the entire tread and spoke images of the third side of the rear wheels.
[0065] When the vehicle enters the exit auxiliary component 532, the vehicle presses over the end trigger module 40, and the pressure received by the end trigger module 40 is greater than the preset pressure, a second trigger signal is generated, and the bottom acquisition modules 10a and 10b of the first area 51, and the side acquisition modules 60a, 60b, 60c and 60d stop acquiring images in response to the second trigger signal.
[0066] See also Figure 5 , Figure 5 This is a structural diagram of the detection system 1 according to the third embodiment of the present application. Compared with the second embodiment, the difference is that the bottom collection module 10 is arranged in the second area 52, and the second area 52 is used to support the wheels on both sides of the vehicle. Specifically, the second area 52 includes a second cover plate 522 and a second groove 523. The detection platform 50 is recessed along the driving direction of the wheels on both sides to form two second grooves 523. Multiple bottom collection modules 10 are sequentially arranged in the second grooves 523 along the driving direction of the vehicle. The reflected or emitted signal of the wheel is incident on the first signal receiving end of the bottom collection module 10 through the top of the second groove 523. The second cover plate 522 is arranged on the second groove 523 and is movably connected to one side of the second groove 523 to prevent other objects from entering the second groove 523. The two second cover plates 522 are flush with each other on the side away from the second groove 523, so that the vehicle can travel smoothly across the detection platform 50. The second cover plate 522 can be a transparent second cover plate 522 or an opaque second cover plate 522. The transparent second cover plate 522 can be made of tempered glass. The opaque second cover plate 522 opposite the first signal receiving end is provided with a through hole, and the through hole is provided with a transparent member, and the transparent member is made of a material such as tempered glass. The first signal receiving end receives the signal from the bottom of the vehicle through the through hole. The first area 51 located between the two second areas 52 may include a second raised portion 513. Specifically, a second raised portion 513 is formed between the two second grooves 523. The raised surface of the second raised portion 513 is flush with the side of the second cover plate 522 away from the second grooves 523, so that the vehicle can pass through the second raised portion 513 smoothly.
[0067] In one application scenario, a vehicle enters the entry assist assembly 531 and presses over the start trigger module 30. When the pressure received by the start trigger module 30 exceeds a preset pressure, a first trigger signal is generated. In response to the first trigger signal, the bottom capture modules 10a, 10b, 10c, and 10d in the second area 52 vertically capture images of the vehicle's bottom as the vehicle moves. For example, after the vehicle enters the second area 52 with the wheel assist assembly 54, when the vehicle is in the first position, the bottom capture modules 10a and 10c capture images of the front tread of the front wheels. The bottom capture modules 10b and 10d capture images of the bottom tread of the front wheels. When the vehicle is in the second position, the bottom capture modules 10a and 10c capture images of the bottom tread of the front wheels. The bottom capture modules 10b and 10d capture images of the bottom tread of the rear wheels. When the vehicle enters the exit auxiliary component 532, the vehicle presses over the end trigger module 40. After the pressure received by the end trigger module 40 is greater than the preset pressure, a second trigger signal is generated, and the bottom acquisition modules 10a, 10b, 10c and 10d of the second area 52 stop acquiring images in response to the first trigger signal.
[0068] It can be understood that since the bottom collection module 10 is disposed in two second grooves 523 respectively recessed along the traveling direction of the wheels on both sides, the detection system 1 of this embodiment can collect more and more complete wheel images.
[0069] See also Figure 6 , and combined with Figure 4 and Figure 5 . Figure 6 This is a schematic diagram of the structure of the detection system 1 according to the fourth embodiment of the present application. This differs from the third embodiment in that both the first area 51 and the second area 52 are provided with bottom collection modules 10. Specifically, the first area 51 includes a first groove 511, and the second area 52 includes a second groove 523 and a second cover plate 522. The bottom collection modules 10 are sequentially arranged in the first groove 511 and in the second groove 523 along the direction of vehicle travel. It can be understood that the detection system 1 of this embodiment can capture both complete vehicle chassis images and complete wheel images.
[0070] The difference from the third embodiment may also be that the detection platform 50 further includes a lifting device 55. The lifting device 55 is used to lift and roll the wheel. The lifting device 55 can be movably installed in the second area 52, or can be movably installed in the first area 51 and the second area 52. It can be understood that the installation position of the lifting device 55 is set according to the position of the wheel when the vehicle is stationary on the detection platform 50. Specifically, taking the lifting device 55 movably installed in the second groove 523 of the second area 52 as an example, the bearing surface of the lifting device 55 is flush with the second cover plate 522 of the second area 52. The lifting device 55 is provided with a lifting sensing module, which is used to generate a lifting trigger signal when sensing that the wheel is located on the bearing surface of the lifting device 55. In response to the lifting trigger signal, the lifting device 55 rises from the second groove 523 to lift the wheel to a preset height and rotate the wheel. The number of lifting devices 55 can be multiple. For example, four lifting devices 55 are located at either end of the two second grooves 523. Each lifting device 55 includes two rollers 551 that roll in the same direction, with the friction of the rollers 551 driving the wheel's rotation. The two rollers 551 can be configured differently to maintain the wheel's position on the lifting devices 55. For example, the two rollers 551 can be spaced a fifth predetermined distance apart, so that the fifth predetermined distance formed by the two rollers 551 can accommodate the rolling wheel. Alternatively, the lifting devices 55 corresponding to the front wheels may roll in a different direction than the lifting devices 55 corresponding to the rear wheels. A bottom acquisition module 10 is located at the position corresponding to the gap between the second grooves 523 and the two rollers 551. The bottom acquisition module 10 captures images of the rolling wheel through the gap and determines the wheel's condition based on the multiple wheel images.
[0071] In one application scenario, the trigger module 30 senses the vehicle and generates a first trigger signal. The bottom capture module 10, located in the gap between the two rollers 551, responds to the first trigger signal and begins capturing images. When the wheel is stationary on the lifting device 55, the lifting device 55 senses the wheel and rises from the second groove 523. The gap between the two rollers 551 fits the wheel, driving it to a predetermined height. The rollers 551 then roll, and the wheel follows suit. The bottom capture module 10, located in the gap, captures images of the rolling wheel.
[0072] It can be understood that since the lifting device 55 can lift and roll the wheel, signals from different positions of the wheel are incident on the first signal receiving end, so that the bottom collection module 10 can collect more and more complete wheel images.
[0073] It is understood that the detection platform 50 of the second embodiment, the third embodiment, and the fourth embodiment can be movably installed on the road, making it convenient for manufacturers to install the detection system 1 in any location. The detection platform 50 includes a variety of detachably connected components, such as a driving assist component 53, a wheel assist component 54, a first cover plate 521, and a second cover plate 522, etc., which facilitate manufacturers to replace components and parts in various modules. For example, a manufacturer can open the first cover plate 521 and replace the bottom collection module 10. In addition, through the detection platform 50, manufacturers can reduce the need for installation measures that damage the installation site, such as digging the ground. The detection platform 50 is easier to install.
[0074] See also Figure 7 , Figure 7 This is a schematic diagram of the structure of a detection system 1 according to a fifth embodiment of the present application. Compared to the first embodiment, the bottom collection module 10 of the detection system 1 of the fifth embodiment is buried within the road. Specifically, one or more third grooves 56 are excavated downward from the road surface, and multiple bottom collection modules 10 are spaced apart within one or more third grooves 56 along the direction of vehicle travel. The first signal receiving end is disposed perpendicularly to the road surface on the bottom collection module 10, and / or the first signal receiving end can be disposed at an adjustable angle on the bottom collection module 10. In one embodiment, a transparent third cover plate 57 is provided on the road surface opposite the bottom collection module 10 to enable the first signal receiving end to receive signals from the bottom of the vehicle. The transparent third cover plate 57 is made of a material such as tempered glass. The side of the transparent third cover plate 57 that supports the vehicle is flush with the road surface, allowing the vehicle to pass smoothly over the transparent third cover plate 57. In another embodiment, a through hole is provided on the road surface opposite the first signal receiving end (not shown). Alternatively, an opaque third cover plate 57 is provided on the road surface opposite the bottom collection module 10. The side of the opaque third cover 57 that supports the vehicle is flush with the road surface, allowing the vehicle to pass smoothly over the opaque third cover 57. The opaque third cover 57, opposite the first signal receiving end, has a through-hole, which is equipped with a transparent member made of a material such as tempered glass. The first signal receiving end receives signals from the bottom of the vehicle through the through-hole.
[0075] In one embodiment, the start trigger module 30 and the end trigger module 40 can also be buried in the road. Specifically, the start trigger module 30 is set in the third groove 56 near the first end of the vehicle, and the end trigger module 40 is set in the third groove 56 away from the second end of the vehicle. The second signal receiving end can be set on the start trigger module 30 or the end trigger module 40 perpendicular to the road surface, or at a preset angle to the road surface. In one embodiment, a transparent third cover plate 57 is provided on the road surface opposite to the start trigger module 30 and the end trigger module 40 so that the first signal receiving end can receive the signal from the bottom of the vehicle. The transparent third cover plate 57 is made of materials such as tempered glass. The side of the transparent third cover plate 57 that supports the vehicle is flush with the road surface so that the vehicle can smoothly drive over the transparent third cover plate 57. In another embodiment, a through hole is provided on the road surface opposite to the first signal receiving end (not shown). Or an opaque third cover plate 57 is provided on the road surface opposite to the start trigger module 30 and the end trigger module 40. The side of the opaque third cover plate 57 that supports the vehicle is flush with the road surface, allowing the vehicle to travel smoothly across the opaque third cover plate 57. A through-hole is provided in the opaque third cover plate 57 opposite the first signal receiving end. A transparent member, made of a material such as tempered glass, is provided in the through-hole in the road surface or the opaque third cover plate 57. The first signal receiving end receives signals from the bottom of the vehicle through the through-hole. In another embodiment, the start trigger module 30 and the end trigger module 40 are positioned on the road. For specific configurations, refer to the first embodiment.
[0076] In one application scenario, a vehicle travels in a certain direction and reaches the start trigger module 30. When the pressure received by the start trigger module 30 reaches a preset pressure threshold, a first trigger signal is generated. The bottom acquisition modules 10a and 10b respond to the first trigger signal. The second signal receiving terminals of the bottom acquisition modules 10a and 10b receive signals from the bottom of the vehicle perpendicular to the road surface. As the vehicle moves, the second signal receiving terminals receive different signals, forming chassis and wheel images at different vehicle positions. When the vehicle reaches the end trigger module 40 and the pressure received by the end trigger module 40 reaches a preset pressure threshold, the end trigger module 40 generates a second trigger signal. The bottom acquisition modules 10a and 10b respond to the second trigger signal and end image acquisition. The processing module 20 determines oil leakage from the vehicle chassis based on the chassis and wheel images at different vehicle positions.
[0077] It is understood that the detection system 1 of this embodiment can be integrated with the scene structure, without the need for an external detection platform 50. Vehicles can travel smoothly on roads equipped with the detection system 1. During vehicle inspection, the vehicle is less likely to shake, and the bottom acquisition module 10 can capture more and more accurate images of the vehicle's bottom, enabling the processing module 20 to more accurately identify whether the bottom condition is abnormal.
