[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] First embodiment

[0051] The invention provides a vehicle-mounted high-definition camera fault diagnosis device.

[0052] Please refer to Figures 1 to 4 In the first embodiment of the present invention, the vehicle-mounted high-definition camera fault diagnosis device includes:

[0053] A box body 1, wherein a material opening 101 is provided at the top of the box body 1;

[0054] The switch mechanism 2 includes a switch plate 21 and a telescopic device 22. The switch plate 21 is slidably mounted in the box body 1. The switch plate 21 is aligned with the range of the material opening 101. The telescopic device 22 is fixedly connected to the box body 1 and the switch plate 21. The telescopic device 22 is used to drive the switch plate 21 to adjust its telescopic structure.

[0055] A test board 3, wherein the test board 3 is fixedly arranged in the box body 1;

[0056] A fill light device 4, the fill light device 4 comprises a rotating member 41, a swing arm 42 and a fill light 43, the rotating member 41 is fixedly arranged in the box body 1, and the swing arm 42 is fixedly connected to the shaft of the rotating member 41 and the fill light 43;

[0057] A lifting mechanism 5, wherein the lifting mechanism 5 is installed in the box body 1, and a camera body 6 is installed on the lifting part of the lifting mechanism 5;

[0058] When the fill light 43 is away from the test board 3 , the fill light 43 is directed toward the test board 3 ; when the fill light 43 is close to the test board 3 , the fill light 43 is directed toward the camera body 6 .

[0059] The inner wall of the box body 1 is coated with anti-reflective material to reduce the reflection of light and prevent the light reflection from drying out the camera body 6 during fault diagnosis.

[0060] In this embodiment, a central control screen (not shown) is integrated outside the box 1, and the central control screen is connected to the camera body 6 after installation. It is used to display the image of the camera body 6 in the lighting environment or reflective environment during the detection process, and the image analysis system recognizes and analyzes the image collected by the camera body 6 to analyze the fault of the camera body 6.

[0061] Fault diagnosis principle:

[0062] During fault diagnosis, the camera body 6 is powered on and connected to the central control screen signal. The camera body 6 collects images of the test board 3 area and displays the collected images through the central control screen. The diagnostic personnel diagnose and analyze whether there is a fault in the image collection of the camera body 6 by comparing the normal collected images with the current collected images; if there is a fault, the camera body 6 does not meet the factory standards; if there is no fault, the camera body 6 meets the exit standards.

[0063] In this embodiment, the rotating member 41 is a motor structure, which provides power for the rotation adjustment of the swing arm 42, thereby facilitating the rotation adjustment of the use mode of the fill light 43.

[0064] In this embodiment, the fill light 43 includes two usage modes:

[0065] In the fill light mode, the light of the fill light 43 is directed toward the test board 3 to provide support for the image acquisition of the camera body 6, and is used to diagnose whether there is a fault in the image acquisition of the camera body 6 under normal lighting conditions;

[0066] In the backlight mode, the light of the fill light 43 is directed toward the camera body 6, providing a backlight environment for fault diagnosis of the camera body 6, and is used to diagnose whether there is a fault in the image acquisition of the camera body 6 in the backlight environment.

[0067] When it is necessary to perform fault diagnosis on the camera body 6, the switch plate 21 is controlled to open by the telescopic device 22 to realize the opening of the material port 101; the camera body 6 to be inspected is installed on the lifting part of the lifting mechanism 5, and the lifting mechanism 5 controls the camera body 6 to move down to the inspection station, and then controls the switch plate 21 to close, and turns on the fill light 43; the fill light 43 fills light toward the test board 3, and the camera body 6 collects the picture on the test board 3 after the fill light;

[0068] When the fill light 43 needs to be switched to a mode, the rotating member 41 is started, the rotating member 41 drives the swing arm 42 to rotate, and the swing arm 42 drives the fill light 43 to rotate synchronously. When the fill light 43 rotates to the range of the isolation baffle 7, the light outlet of the fill light 43 is blocked, so that the camera body 6 can perform fault diagnosis in a weak light environment; when the fill light 43 continues to rotate to the backlight mode, the fill light 43 leaves the range of the isolation baffle 7 and shines toward the camera body 6, so that the camera body 6 can perform fault diagnosis in a backlight environment, thereby realizing fault diagnosis in different lighting environments under the control of the fill light 43;

[0069] Finally, when the rotating member 41 drives the fill light 43 to switch from the fill light mode to the backlight mode, fault diagnosis support in a low-light environment can be provided for the camera body 6 .

[0070] Furthermore, color plates of different colors are evenly arranged on the test board 3, so as to facilitate the recognition of the color acquisition of the camera body 6.

[0071] The test surface of the test board 3 is in a grid structure, and color plates of different colors are integrated and installed in different grid ranges to detect the recognition of different colors by the camera body 6.

[0072] Please refer again Figure 1 The top of the box 1 is a removable cover structure, which is convenient for inspection and maintenance of the equipment inside the box 1.

[0073] Please refer to Figure 2 and Figure 4 The vehicle-mounted high-definition camera fault diagnosis device also includes an isolation baffle 7, which is fixed in the box body 1. The isolation baffle 7 is L-shaped and is arranged around the rotation range of the fill light 43.

[0074] The isolation baffle 7 is staggered with the swing arm 42 and the fill light 43 , respectively. When the swing arm 42 drives the fill light 43 to rotate and adjust, the isolation baffle 7 will not collide with the fill light 43 or the swing arm 42 .

[0075] When the swing arm 42 drives the fill light 43 to switch from the fill light mode to the backlight mode, when the fill light 43 reaches the range of the isolation baffle 7, the isolation baffle 7 blocks the light of the fill light 43, so that the image acquisition range of the camera body 6 is in a low-light environment; without turning off the fill light 43, support is provided for fault diagnosis of the camera body 6 in a low-light environment.

[0076] Because, when diagnosing faults of batch camera bodies 6 before they are shipped, a switch is used to drive the fill light 43 to be extinguished. In a detection cycle, the fill light 43 needs to be turned on and off more frequently. Frequent switching has an impact on the filament or electronic components, and is likely to affect the normal lighting and service life of the bulb.

[0077] Therefore, in this embodiment, the light mode can be switched without turning off the fill light 43 , thereby reducing the frequent switching operations of the fill light 43 when used in different modes and extending the service life of the fill light 43 .

[0078] Please refer again Figure 2 The lifting mechanism 5 includes a telescopic member 51 and a lifting platform 52 . The telescopic member 51 is installed in the box body 1 . The telescopic member 51 is used to drive the lifting platform 52 to move up and down. The camera body 6 is assembled on the lifting platform 52 .

[0079] The telescopic member 51 conveniently drives the lifting platform 52 to be raised and lowered, and the lifting platform 52 simultaneously drives the installed camera body 6 to be raised and lowered, so that after the switch plate 21 is opened, the camera body 6 after fault diagnosis can be lifted upward to facilitate the installation and disassembly of the camera body 6.

[0080] In this embodiment, the camera body 6 is plugged into the lifting platform 52 , and after being plugged in, an interference fit is formed, which facilitates the installation or removal of the camera body 6 and the lifting platform 52 .

[0081] Furthermore, the lifting mechanism 5 also includes a limiting shaft 53 , the bottom of which is fixed on the box body 1 , and the top of which passes through the lifting platform 52 and is slidably connected thereto, and the lifting platform 52 is slidably connected to the box body 1 .

[0082] The limiting shaft 53 provides auxiliary support and limiting functions for the up and down movement of the lifting platform 52, thereby improving the stability of the lifting and lowering adjustment of the lifting platform 52.

[0083] Please refer again Figure 1 The vehicle-mounted high-definition camera fault diagnosis device also includes four legs 8, which are fixed to the bottom of the box body 1, and the four legs 8 are distributed around the bottom of the box body 1.

[0084] The legs 8 provide auxiliary support for the installation and use of the box body 1.

[0085] In an optional implementation manner of the present embodiment, the telescopic device 22 is an electric telescopic rod, which is used to directly drive the switch plate 21 to move and adjust, so as to realize the switch adjustment of the material opening 101.

[0086] The working principle of the vehicle-mounted high-definition camera fault diagnosis device provided in this embodiment is as follows:

[0087] like Figure 3 and Figure 4 As shown, it may be defined that in the initial state, the camera body 6 is installed on the lifting platform 52, the lifting platform 52 is in the detection state, the fill light 43 is in the fill light mode, and the switch board 21 is in the closed state;

[0088] When the fill light 43 is in the fill light mode, it is convenient for the camera body 6 to collect images and perform fault diagnosis in the fill light mode;

[0089] Please refer to Figures 4 to 5 to Figure 6 When the diagnosis of the camera body 6 in the fill light mode is completed, the rotating member 41 is started, the rotating member 41 drives the swing arm 42 to rotate, and the swing arm 42 drives the fill light 43 to rotate clockwise. When the fill light 43 rotates, it first passes through the range of the isolation baffle 7. When the fill light 43 completely enters the range of the isolation baffle 7, the light of the fill light 43 is blocked, and the box 1 is in a low-light environment, which is convenient for the picture acquisition fault diagnosis of the camera body 6 in a low-light environment;

[0090] When the fill light 43 continues to rotate clockwise and leaves the range of the isolation baffle 7, and rotates to the backlight mode, the rotating member 41 is closed, and the light of the fill light 43 is directed toward the camera body 6, so as to facilitate the picture acquisition fault diagnosis of the camera body 6 in the backlight environment;

[0091] like Figure 6 As shown, the lifting platform 52 is in the detection state, the fill light 43 is in the backlight mode, and the switch plate 21 is in the closed state;

[0092] When the fault diagnosis of the camera body 6 in the backlight environment is completed, the rotating part 41 is started again to switch the fill light 43 from the backlight mode to the fill light mode; thereafter, the telescopic device 22 is started, and the telescopic device 22 drives the switch plate 21 to open, and the telescopic part 51 is started, and the telescopic part 51 drives the lifting platform 52 and the camera body 6 to move upward, so that the camera body 6 is lifted to the range of the material port 101, so as to facilitate the replacement of the camera body 6 that needs fault diagnosis.

[0093] Second embodiment

[0094] Please refer to Figures 7 and 8Based on the vehicle-mounted high-definition camera fault diagnosis device provided by the first embodiment of the present invention, the second embodiment of the present invention provides another vehicle-mounted high-definition camera fault diagnosis device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0095] Specifically, the difference of the vehicle-mounted high-definition camera fault diagnosis equipment provided by the second embodiment of the present invention is that the telescopic device 22 includes an elastic contraction part 221, a first transmission rod 222, a second transmission rod 223 and a synchronization shaft 224, the elastic contraction part 221 elastically connects the box body 1 and the first transmission rod 222, the top of the synchronization shaft 224 is fixedly connected to the switch plate 21, the two ends of the second transmission rod 223 are hinged to the first transmission rod 222 and the bottom of the synchronization shaft 224, and the first transmission rod 222 is aligned within the rotation range of the swing arm 42.

[0096] In this embodiment, the switch plate 21 can only be moved and adjusted horizontally on the box body 1; when the switch plate 21 is contracted, the material opening 101 is opened; when the switch plate 21 is extended, the material opening 101 is closed.

[0097] The switching principle of the switch board 21 is:

[0098] When the camera body 6 is in a fault diagnosis state, the switch board 21 is maintained in a closed state;

[0099] When the fault diagnosis of the camera body 6 is completed and the fill light 43 in the backlight mode needs to be reset, the rotating member 41 is started, and the rotating member 41 drives the swing arm 42 and the fill light 43 to rotate clockwise, and the swing arm 42 contacts and pushes the first transmission rod 222 to move. When the first transmission rod 222 moves, the second transmission rod 223 pushes the synchronization shaft 224 to contract, and the synchronization shaft 224 drives the switch plate 21 to contract adaptively, so that the switch plate 21 is automatically opened;

[0100] When the fill light 43 continues to rotate to reset, the swing arm 42 continues to rotate, and the elastic contraction member 221 pulls the first transmission rod 222 to gradually shrink and reset. When the swing arm 42 drives the fill light 43 to reset to the fill light mode, the first transmission rod 222 shrinks and resets, and at the same time, the second transmission rod 223 pulls the synchronization shaft 224 to extend, and the synchronization shaft 224 drives the switch plate 21 to extend and completely close at the material port 101.

[0101] Finally, while the rotating member 41 drives the fill light 43 to adjust from the backlight mode to the fill light mode, the switch plate 21 is turned on and off. After the switch plate 21 is opened, the camera body 6 is easily replaced; the rotating member 41 can be used to switch the position of the fill light 43, and the adaptive switch control of the switch plate 21 can be synchronously realized during the switching process.

[0102] Preferably, two elastic contraction members 221 are provided (not shown in the figure), the two elastic contraction members 221 are arranged in parallel, and the elastic contraction members 221 are arranged in a staggered manner with respect to the rotation range of the swing arm 42. The provision of the elastic contraction member 221 will not affect the rotation of the swing arm 42.

[0103] In an optional implementation of this embodiment, the telescopic member 51 may be an independent telescopic cylinder, the bottom of the telescopic member 51 is fixedly connected to the box body 1, and the telescopic part of the telescopic member 51 is fixedly connected to the bottom of the lifting platform 52. It is used to directly drive the lifting and lowering adjustment of the lifting platform 52, so as to facilitate the independent control of the lifting of the camera body 6 during installation and removal.

[0104] In another optional implementation of this embodiment, please refer to Figure 7 The telescopic member 51 is a spring retractable rod structure, the two ends of the telescopic member 51 are hinged to the lifting platform 52 and the switch plate 21, and a limiting convex point is provided on the top of the limiting shaft 53;

[0105] When the lifting platform 52 moves up to the position of the limit protrusion, the lifting platform 52 cannot move up further.

[0106] When the switch plate 21 contracts to open the material opening 101, the switch plate 21 pulls the lifting platform 52 upward synchronously through the telescopic member 51, and the lifting platform 52 moves upward while driving the camera body 6 after the fault diagnosis to move upward; the material opening 101 is opened while the camera body 6 moves upward, so as to facilitate the replacement of the camera body 6 after the fault diagnosis;

[0107] When the switch plate 21 is extended to close the material opening 101, the switch plate 21 synchronously pushes the lifting platform 52 downward through the telescopic member 51, and the lifting platform 52 moves downward while driving the camera body 6 after the fault diagnosis to move downward; the material opening 101 is closed while the camera body 6 moves downward, so as to facilitate the fault diagnosis of the camera body 6 after replacement;

[0108] Finally, under the driving action of the rotating member 41 , the switching of the position of the fill light 43 , the adaptive switching of the switch board 21 , and the adaptive lifting and lowering adjustment of the camera body 6 are synchronously realized.

[0109] The working principle of the vehicle-mounted high-definition camera fault diagnosis device provided in this embodiment is as follows:

[0110] Please refer to Figures 8 to 9 and Figures 7 to 10 When the fill light 43 is in the backlight mode and the fault diagnosis of the camera body 6 is completed, the rotating member 41 is started, and the rotating member 41 drives the swing arm 42 and the fill light 43 to rotate clockwise to achieve the reset adjustment of the fill light 43;

[0111] During the reset adjustment of the fill light 43, the swing arm 42 first pushes the first transmission rod 222 to extend, and the first transmission rod 222 pulls the switch plate 21 to adaptively contract through the second transmission rod 223 and the synchronization shaft 224, thereby realizing the opening of the material port 101;

[0112] When the switch plate 21 is retracted, the lifting platform 52 is synchronously pulled upward by the telescopic member 51, and the lifting platform 52 is moved upward while the camera body 6 is driven upward, so that the switch plate 21 is opened and the camera body 6 is moved upward after the fault diagnosis, so as to facilitate the replacement of the camera body 6;

[0113] When the fill light 43 is reset to the fill light mode, the swing arm 42 continues to rotate and reset, and the elastic contraction member 221 pulls the first transmission rod 222 to shrink and reset, and the first transmission rod 222 pushes the switch plate 21 to extend adaptively through the second transmission rod 223 and the synchronization shaft 224, so as to realize the automatic closing of the material port 101;

[0114] When the switch plate 21 is extended, the lifting platform 52 is synchronously pushed downward by the telescopic member 51. When the lifting platform 52 moves downward, the camera body 6 is driven downward to simultaneously close the switch plate 21 and move downward the camera body 6 after replacement, so as to facilitate the detection and return of the camera body 6 after replacement.

[0115] Finally, under the driving action of the rotating member 41 , the switching of the position of the fill light 43 , the adaptive switching of the switch board 21 , and the adaptive lifting and lowering adjustment of the camera body 6 are synchronously realized.
