[0043] During the test, the flight ranging module 1 to be tested is first placed on the module mounting platform 4, and the emission center of the flight ranging module 1 is aligned with the graphic center of the first reflection chart 2, so that the emission center and the graphic center are concentric, and the driving member 5 is started. The driving member 5 drives the module mounting platform 4 to slide along the length direction on the track 3 until the distance between the flight ranging module 1 and the first reflection chart 2 is adjusted to the first test distance. The driving member 5 stops driving the module mounting platform 4 to move. At this time, the first test distance test of the flight ranging module 1 is carried out, and at the first test distance, all module products to be tested are placed one by one on the module mounting platform 4. , to carry out testing. After the first test distance of all flight ranging modules 1 is tested, the driving component 5 is started again. The driving component 5 automatically drives the module mounting platform 4 to move, and the distance between the flight ranging module 1 and the first reflection chart 2 is automatically adjusted to the second test distance and tested. The above test work is repeated until all flight ranging modules 1 are tested at multiple test distances. During the whole process, the adjustment of the distance between the flight ranging module 1 and the first reflection chart 2 is automatically realized by the driving component 5, with a high degree of automation and high test efficiency. The multiple test distances are automatically adjusted by the driving component 5, with high precision and small deviation.

[0044] Specifically, refer to Figure 1 As shown, the first reflective card 2 includes a card body 21 and a placement frame 22, the placement frame 22 and the card body 21 are both vertically arranged, the card body 21 is detachably connected to the placement frame 22, the track 3 is horizontally arranged, and the track 3 is composed of two parallel single tracks 3. At this time, the two sides of the module mounting platform 4 are respectively located on the two single tracks 3 and slide along the length direction of the track 3. The setting of the two single tracks 3 at this time makes the sliding of the module mounting platform 4 more stable, and the two single tracks 3 are connected by a welding plate 11, and the two ends of the welding plate 11 are respectively welded to the two single tracks 3 to achieve the fixation of the two single tracks 3. At the same time, a plurality of welding plates 11 are provided to stably weld the two single tracks 3 together.

[0045] As a specific implementation method, refer to Figure 1-2 As shown, the track 3 is composed of multiple horizontally arranged track bodies 31, and the multiple track bodies 31 are arranged in sequence along the length direction of the track 3. A connecting piece 8 is provided between two connected track bodies 31, and two adjacent track bodies 31 are connected by the connecting piece 8 therebetween to achieve fixation between the multiple track bodies 31.

[0046] Specifically, the connecting member 8 includes a horizontally arranged connecting plate 81, which extends along the length direction of the track body 31. The two ends of the connecting plate 81 are detachably connected to the two adjacent sections of the track body 31, and one section of the track body 31 can be moved along the length direction of the connecting plate 81 to adjust the distance between the two adjacent sections of the track body 31. The other section of the track body 31 can be moved along the height direction of the connecting plate 81 to adjust the relative height of the two sections of the track body 31. The connection between the two adjacent sections of the track body 31 can be achieved through the connecting plate 81, and at the same time, the distance and relative height between the two sections of the track body 31 can be adjusted more conveniently, so that the track body 31 is adjusted to the optimal position.

[0047] The connecting plate 81 is provided with a first waist-shaped hole 82 arranged along its length direction, and the track body 31 near the first waist-shaped hole 82 is bolted to the connecting plate 81 through the first waist-shaped hole 82. The connecting plate 81 is provided with a second waist-shaped hole 84 arranged along its height direction, and the first waist-shaped hole 82 and the second waist-shaped hole 84 are respectively located on both sides of the connecting plate 81, and the track body 31 near the second waist-shaped hole 84 is bolted to the connecting plate 81 through the second waist-shaped hole 84;

[0048] In order to realize the bolt connection between the track body 31 and the connecting plate 81 through the first waist-shaped hole 82, a horizontally arranged first positioning bolt 83 is arranged in the first waist-shaped hole 82, and the end of the first positioning bolt 83 facing away from its nut extends into the corresponding track body 31 and is threadedly connected with the section of the track body 31. The first positioning bolt 83 has a first state and a second state. When the first positioning bolt 83 is in the first state, the first positioning bolt 83 can slide along the length direction of the first waist-shaped hole 82, so as to adjust the distance between the two adjacent sections of the track body 31, to fine-tune the length of the entire track body 31, so that the length accuracy of the track body 31 is adjusted to the length required for the test. When the first positioning bolt 83 is in the second state, the nut of the first positioning bolt 83 and the connecting plate 81 are tightly pressed, and the first positioning bolt 83 at this time cannot slide in the first waist-shaped hole 82, thereby limiting the sliding of the first positioning bolt 83, so that the two adjacent sections of the track body 31 cannot move horizontally, thereby ensuring the stability of the track 3.

[0049] In order to realize the bolt connection between another section of the track body 31 and the connecting plate 81 through the second waist-shaped hole 84, a second positioning bolt 85 is arranged in the second waist-shaped hole 84, and the end of the second positioning bolt 85 facing away from its nut extends into the corresponding track body 31 and is threadedly connected to the track body 31. The second positioning bolt 85 also has a first state and a second state. When the second positioning bolt 85 is in the first state, the second positioning bolt 85 can slide along the length direction of the second waist-shaped hole 84 to fine-tune the height of the section of the track body 31 until all the track bodies 31 are at the same height and horizontal, so that the entire track 3 is fine-tuned to a horizontal state. When the second positioning bolt 85 is in the second state, the nut of the second positioning bolt 85 and the connecting plate 81 are pressed tightly, thereby limiting the sliding of the second positioning bolt 85, so that the track body 31 cannot move in the vertical direction, thereby ensuring the stability of the track body 31.

[0050] At the same time, for the connecting plates 81, two can be arranged between two adjacent sections of the track body 31, and the two connecting plates 81 are respectively located at the two single tracks 3. Through the arrangement of the two connecting plates 81, and the first waist-shaped hole 82 and the first waist-shaped hole 82 are opened at the same position on the connecting plate 81, the first positioning bolt 83 and the second positioning bolt 85 are also arranged. When the first positioning bolt 83 and the second positioning bolt 85 are both in the second state, the connection between the two adjacent sections of the track body 31 can be made more stable.

[0051] As another embodiment, referring to Figure 1 and Figure 2 As shown, each section of the track body 31 is provided with a height adjustment component 9 for adjusting the height of each section of the track body 31. Specifically, the height adjustment component 9 includes a screw rod 91 arranged at the bottom of each section of the track body 31. The screw rod 91 is vertically arranged, and one end of the screw rod 91 toward the bottom of the track body 31 extends into the corresponding track body 31 and is threadedly connected to the track body 31. A support seat 92 is arranged at the end of the screw rod 91 facing away from the track body 31, and the track body 31 is supported by the support seat 92. When each section of the track body 31 adjusts the height of the section of the track 3 through the second waist hole 84 and the second positioning bolt 85, and the track 3 is fine-tuned to the horizontal, the screw rod 91 is also rotated at this time to drive the support seat 92 to move up and down, and cooperate with the second positioning screw 91 to keep the support seat 92 in contact with the ground, so that the track 3 placed on the ground is more stable.

[0052] In order to facilitate the transportation of the track 3, the test equipment also includes a plurality of universal wheels 10, and the plurality of universal wheels 10 are respectively arranged at the bottom of each section of the track body 31, and at the same time, the two single tracks 3 are correspondingly provided with a plurality of universal wheels 10. Through the setting of the universal wheels 10, when in use, the universal wheels 10 are in contact with the ground. When the track 3 is pushed, the universal wheels 10 rotate, changing sliding into rolling, making it more convenient and quick to move the track 3. At the same time, when moving, the screw 91 rotates at this time so that the support seat 92 does not contact the ground, avoiding friction between the support seat 92 and the ground when the track 3 moves, resulting in friction loss of the support seat 92. At the same time, when testing, the screw 91 is rotated again to make the support seat 92 contact with the ground. At this time, the track 3 will not move easily under the action of the support seat 92, thereby ensuring the stability of the test.

[0053] As a specific implementation method, refer to Figure 3-Figure 5 As shown, the driving member 5 includes a driving motor 51, a gear 52 and a rack 53, wherein the driving motor 51 is arranged on the track 3 and is located below the module mounting platform 4, so as not to affect the sliding of the module mounting platform 4 on the track 3, the gear 52 is arranged on the output shaft of the driving motor 51, the driving motor 51 drives the gear 52 to rotate around its axis, the rack 53 is arranged along the length direction of the track 3, the rack 53 and the gear 52 are meshed, and the rack 53 is installed at the bottom of the module mounting platform 4 and connected to the bottom of the module mounting platform 4, when the gear 52 rotates, the rack 53 slides along its length direction and drives the module mounting platform 4 to move along the length direction of the track 3, so as to realize the automatic movement of the module mounting platform 4, to adjust the distance between the flight ranging module 1 and the first reflection chart 2 on the module mounting platform 4, so as to facilitate the automatic adjustment of the multi-stage test distance. On the contrary, if the rack 53 is arranged on the track 3 and the gear 52 is arranged on the module mounting platform 4, the module mounting platform 4 can also be moved along the length direction of the track 3. In this embodiment, the driving member 5 is not limited to the driving motor 51 , the gear 52 and the rack 53 , and other driving methods can also be used as long as the module mounting platform 4 can be driven to slide along the length direction of the track 3 .

[0054] As another embodiment, referring to Figure 4 and Figure 5As shown, the test equipment also includes a second reflection chart 6, which is arranged on the end of the track 3 facing away from the first reflection chart 2. The structure of the second reflection chart 6 is similar to that of the first reflection chart 2, wherein the first reflection chart 2 is set to a 1.4m*1.4m chart, and the second reflection chart 6 is a 1.8m*1.8m chart, so that the first reflection chart 2 can test a short distance, and the second reflection chart 6 can test a long distance. The flight ranging module 1 is rotatably arranged on the module mounting platform 4, so that the flight ranging module 1 can rotate 180 degrees toward the first reflection chart 2 or the second reflection chart 6. When the flight ranging module faces the second reflection chart 6, the emission center of the flight ranging module is concentric with the graphic center of the second reflection chart 6. During the test, based on the test requirements, the distance between the first reflection chart 2 and the second emission chart 6 is reasonably set, so that when the flight ranging module 1 stays at a certain position, It can satisfy both the test distance to the first transmitting chart 2 and the test distance to the second transmitting chart 6. Therefore, when the distance between the flight ranging module 1 and the first reflection chart 2 is adjusted to the first test distance through the driving member 5, the emission center of the flight ranging module 1 and the graphic center of the first reflection chart 2 are concentric, and then the test is performed. Since the distance between the first transmitting chart 2 and the second transmitting chart 6 has been reasonably set before, the distance between the flight ranging module 1 and the second transmitting chart 6 also satisfies the test distance. Therefore, the flight ranging module 1 can be directly rotated to rotate 180 degrees until it faces the second reflection chart 6. The emission center of the flight ranging module 1 and the graphic center of the second reflection chart 6 are concentric, and another test distance is performed on the second reflection chart 6. It only needs to rotate the flight ranging module 1 to complete the test of the two test distances, which greatly improves the test efficiency.

[0055] In order to enable the flight ranging module 1 to rotate on the module mounting platform 4, a vertically arranged placement column 7 is provided on the module mounting platform 4. The flight ranging module 1 is sleeved on the placement column 7 and can rotate on the placement column 7 so that the flight ranging module 1 faces the first reflection chart 2 or the second reflection chart 6. At this time, the placement column 7 can not only enable the flight ranging module 1 to rotate, but also prevent the flight ranging module 1 from shaking back and forth and left and right. The module can only move and rotate in the vertical direction, thereby improving the stability of the test.

[0056] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
