[0060] like Figures 4 to 6 As shown, in a specific example provided in the present application, the adjusting device 3 includes a first motor 31 and a rotating support 32; the first motor 31 is installed at the bottom of the installation chamber 11; the rotating support 32 includes a connecting seat 321 and a rotating bracket 322, the connecting seat 321 is connected to the output shaft of the first motor 31 through a coupling, so as to realize the rotation adjustment of the rotating support 32 driven by the first motor 31 in the first plane, and the bottom of the rotating bracket 322 is connected to the connecting seat 321; the clamping mechanism 33 is installed at the upper end of the rotating bracket 322.

[0065] like Figure 4 、 Figure 6 and Figure 7 As shown, in a specific embodiment provided by the present application, the clamping seat 331 has a connecting plate 3311 and a test plate 3312 that are relatively arranged, and an upper support plate 3313 and a lower support plate 3314 are provided between the connecting plate 3311 and the test plate 3312, and an adjustment slot 33121 is provided on the test plate 3312; an upper blocking bar 3315, a lower blocking bar 3316, a left blocking bar 3317 and a right blocking bar 3318 are provided on the outer surface of the test plate 3312, wherein the upper blocking bar 331 5.

One end of the clamping arm 3323, located in the adjustment slot 33121, is connected to the movable block 3322. It should be noted that the specific structure of the upper blocking bar 3315, the lower blocking bar 3316, the left blocking bar 3317, and the right blocking bar 3318 is not limited, and any structure that forms a placement area for the radar 6 under test is sufficient.

[0067] During the installation or removal process of the radar 6 under test in the placement area, there is a risk of falling, causing damage to the radar 6 under test.

[0068] During actual use, the first cylinder 3411 and the second cylinder 3421 push the first telescopic hinge 3412 and the second telescopic hinge 3422 to unfold respectively, and the opened receiving net 343 is used to receive the fallen radar 6 to avoid loss caused by damage to the radar 6.

[0069] like Figures 4 to 7 As shown, in a specific embodiment provided by the present application, the adjustment device 3 further includes a pin mechanism 35; the pin mechanism 35 includes a telescopic cylinder 351, a lifting platform 352, and a connecting plug 353; the telescopic cylinder 351 is mounted on the rotating support 32 and is used to drive the lifting platform 352 to adjust the relative height position of the lifting platform 352 with respect to the rotating support 32; the lifting platform 352 is mounted on the telescopic end of the telescopic cylinder 351; and the connecting plug 353 of the electrically connected control device is mounted on the lifting platform 352 for plugging into the radar under test 6. Connecting to the radar under test 6 through the pin mechanism 35 to obtain test data of the radar under test 6 ensures that the target simulator constitutes a target object and the test benchmark of the radar under test 6. It should be noted that, in this embodiment, the target object simulator includes a first reflector and a second reflector. When the reflection intersection point of the first reflector and the second reflector is aligned with the calibration object on the radar to be tested 6, it indicates that the target object composed of the target object simulator is the test benchmark of the radar to be tested 6. The angle between the radar to be tested 6 and the target object simulator is adjusted on this benchmark, and the test data of the radar to be tested 6 is obtained.

[0070] like Figure 9 and Figure 10As shown, in a specific embodiment provided by the present application, the calibration device 4 includes a rotating platform 41, a UVW platform 42, a lifting and lowering platform 43, and a tilt adjustment platform 44, which are stacked from bottom to top. The bottom of the rotating platform 41 is fixed to the bottom of the installation chamber 11. The UVW platform 42 is mounted on the top of the rotating platform 41. The lifting and lowering platform 43 is mounted on the top of the UVW platform 42. The tilt adjustment platform 44 is mounted on the top of the lifting and lowering platform 43.

In this embodiment, the tilt adjustment platform 44 includes a left and right pitch motor assembly 441 and a front and back pitch motor assembly 442. The left and right pitch motor assembly 441 and the front and back pitch motor assembly 442 are stacked together, or the front and back pitch motor assembly 442 and the left and right pitch motor assembly 441 are stacked together.

It is worth mentioning that this application does not limit the positional relationship between the lifting motor, UVW platform 42, rotating platform 41, and tilt adjustment platform 44, and this application does not limit the specific structure of the lifting motor, UVW platform 42, rotating platform 41, and tilt adjustment platform 44. The specific structure that can achieve the corresponding function can be selected according to actual conditions.

[0072] During the test of the radar 6 to be tested, it is necessary to detect the detection effect between the radar and the target at different distances, or when testing different categories of radars 6 to be tested, each category of radar 6 to be tested needs to test the target at different distances. In order to solve the above problems, several target test points at different distances are often set. When the target data at the corresponding distance needs to be tested, the target is moved to the preset test point to complete the data test of the radar 6 to be tested. The above problems still exist that the test distance is relatively fixed and cannot be adjusted at will, the application range is small, and there are certain risks in manually moving the target. For this reason, Figure 1 and Figure 2As shown, a specific embodiment provided in this application further includes a linear module 5 mounted at the bottom of the installation chamber 11; the calibration device 4 is mounted on the movable slider of the linear module 5. Specifically, the travel distance between the calibration device 4 and the radar under test 6 in this embodiment is 0.8m-3.2m, which can be set according to actual needs and is not limited here. It should be noted that the linear module 5 in this embodiment is a conventional mechanical structure capable of achieving linear motion of the calibration device 4, and will not be described in detail here.

[0073] In actual use, the linear module 5 is used to adjust the positional relationship between the calibration device 4 and the adjustment device to obtain test data at different distances between the radar under test 6 and the target object, thereby expanding the detection application range of the present application. The linear module of the present application is steplessly adjusted by the control device to ensure adjustment accuracy and expand the test range of the radar under test 6.

[0074] like Figure 1 and Figure 3 As shown, in a specific example provided in this application, the test system also includes a display screen 101, a touch start switch 102, a main power switch 103, a barcode scanner 106 and a three-color light 104, and the above components are all electrically connected to the processing and analysis module. During specific use, the main power switch 103 is turned on, and then the start switch 102 is touched with one hand. The product code on the shell of the radar under test 6 is aligned with the muzzle of the code scanning gun 106. Then, the radar under test 6 after scanning is placed in the placement area and clamped by the clamping mechanism 33. The pin mechanism 35 inserts the connecting plug 353 into the radar under test 6 to obtain the test data of the radar under test 6; the target simulator and the radar under test 6 are calibrated and aligned by the calibration device 4, and then the relative angle between the radar under test 6 and the target simulator is changed by the adjustment device 3.
