Technical Field
[0001] The present invention relates to the field of radar testing, and in particular to a testing device and a testing method for a millimeter-wave radar. Background Art
[0002] Millimeter-wave radar operates in the millimeter-wave band. Millimeter waves typically fall between 30 and 300 GHz (with wavelengths of 1 to 10 mm). Millimeter-wave wavelengths lie between microwaves and centimeter waves, so millimeter-wave radar combines the advantages of both microwave and optoelectronic radars.
[0003] Millimeter-wave radars often require testing during the R&D phase. The current common approach is to install the millimeter-wave radar on a real test vehicle and then complete the test. However, for some scenarios where the radar needs to remain stationary or the test vehicle cannot enter, rapid data collection is sometimes necessary to verify the algorithm.
[0004] Patent CN203365672U proposes a millimeter-wave radar test system. This system fixes the millimeter-wave radar to a fixed stand that simulates the front bumper of a real vehicle. It also sets targets within the millimeter-wave radar's detection range to simulate actual road conditions. Combined with a camera and a host computer, the system tests the millimeter-wave radar's operating stability, reliability, and target detection accuracy without using a real vehicle.
[0005] The above patent still has some problems when used. The test accuracy of the millimeter-wave radar is not high, and the stability of the millimeter-wave radar under the measurement state cannot be guaranteed.

[0011] Preferably, the millimeter-wave radar control component includes: an electric push rod installed on the top of the sliding plate, a limit seat rotatably installed on the telescopic top of the electric push rod, a control motor installed inside the limit seat, a mounting plate key-connected and installed on the top of the control motor; and a millimeter-wave radar body installed on the upper part of the mounting plate for testing.
[0012] Preferably, the millimeter-wave radar body is slidably installed inside the test frame, and the two groups of rotating baffles are respectively arranged to rotate in accordance with the two groups of inclined surfaces of the fan-shaped platform. Each group of rotating baffles is provided with several groups of mounting holes, and the test assembly is arranged at a position corresponding to each group of mounting holes.
[0013] Preferably, the test assembly comprises: a monitoring probe plugged and installed in the installation hole, an indicator light connected to the end of the monitoring probe; and an object to be detected arranged at the front end of the monitoring probe.
[0014] Preferably, the linkage assembly includes: an installation box fitted on the top of the test stand, a motor installed on the upper part of the installation box, a main gear key-connected and installed on the output end of the motor, two sets of auxiliary gears rotatably installed inside the installation box, and a connecting shaft fixedly installed at the bottom of the auxiliary gear.
[0015] Preferably, the main gear and the two sets of auxiliary gears are both arranged inside the installation box, the main gear is meshed with the two sets of auxiliary gears, and the two sets of connecting shafts are respectively fixedly connected to a set of rotating baffles.
[0016] Based on the above-mentioned millimeter-wave radar testing device, the present invention also relates to a testing method for the millimeter-wave radar testing device, comprising the following steps:
[0017] S1. The sliding plate is controlled to move by the roller screw, so that the operating position of the electric push rod and the millimeter-wave radar body is adjusted, and the operating position of the millimeter-wave radar body from the sector platform is changed, so that the millimeter-wave radar body can measure the sensitivity to the same obstacle at different positions. The height of the millimeter-wave radar body is controlled by the electric push rod to measure the detection effect of different obstacles in different vertical directions.
[0018] S2. Control the movement of the roller screw to make the electric push rod fit into the arc groove to fix the use position of the millimeter-wave radar body. Then, control the motor to change the angle of the millimeter-wave radar body to measure the detection effect of the millimeter-wave radar body against the same obstacle at different angles.
[0019] S3. The internal motor of the inner rod controls the rotation of the conveyor wheel, so that the test plate can move back and forth around the fan-shaped table along with the arc limit seat, so that the millimeter-wave radar body can be fixed in a position to perform sensitivity tests on fast-moving objects. At the same time, the telescopic push rod can be used to control the lifting and lowering of the arc limit seat to change the moving height of the test plate. In the sensitivity test of the millimeter-wave radar body, different ranges of test conditions are provided for the millimeter-wave radar body, so that the millimeter-wave radar body can measure detection data more accurately.
[0020] S4. The motor controls the rotation of the main gear, thereby driving the two sets of connecting shafts to rotate, so that the two sets of rotating baffles that fit the outer surface of the fan-shaped platform open and close, thereby changing the control of the use angle of the monitoring probe, and then testing the monitoring range of the millimeter-wave radar body when the position of the millimeter-wave radar body is fixed. After measuring the maximum detection range of the millimeter-wave radar body, the monitoring probe is randomly controlled to extend to test the detection sensitivity of the millimeter-wave radar body within the extreme range.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] The millimeter-wave radar body is moved by controlling the roller screw, and the electric push rod is used to control the lifting and lowering of the millimeter-wave radar body, so that the millimeter-wave radar body has a multi-angle detection path during the detection process, and the use angle of the millimeter-wave radar body is changed by controlling the motor to test the extreme detection range of the millimeter-wave radar body.
[0023] By setting an arc-shaped limit seat to limit the movement of the test board, it is possible to ensure that the millimeter-wave radar body can be tested in a wide range of sensitivity when the position of the millimeter-wave radar body is fixed. By increasing the height of the arc-shaped limit seat by telescopic push rod, the capture effect of the test board status within the detection range can be improved when the position of the millimeter-wave radar body is fixed, and the flexibility of the millimeter-wave radar body can be better measured.
[0024] By turning the baffle open and closed, the use angle of the monitoring probe is changed, so that the millimeter-wave radar body continues to monitor until the monitoring probe leaves the monitoring range of the millimeter-wave radar body, thereby measuring the monitoring range of the millimeter-wave radar body at a fixed position.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.
[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationships and movement conditions between various components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0035] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0036] like Figure 1-7 As shown, the present invention provides a test device for a millimeter-wave radar, comprising a mounting base 1; a limiting plate 2 fixedly mounted on the right side of the mounting base 1, a fan-shaped platform 3 fixedly mounted on the upper part of the mounting base 1, and an arc-shaped groove 4 opened on the small end surface of the fan-shaped platform 3; a movable component mounted on the upper part of the limiting plate 2, a detection component movably mounted on the outer arc surface of the fan-shaped platform 3; a millimeter-wave radar control component movably mounted on the right side of the arc-shaped groove 4; a test frame 18 arranged on the upper part of the limiting plate 2, two groups of rotating baffles 19 rotatably mounted at both ends of the test frame 18, a test component mounted on the outside of each group of rotating baffles 19; and a linkage component for connecting the test frame 18 and the rotating baffle 19.
[0037] As a preferred embodiment, the detection component includes: an arc-shaped limit seat 5 movably fitted on the outer arc surface of the fan-shaped platform 3, a cavity opened inside the arc-shaped limit seat 5, and an inner slide groove 6 opened on the inner wall of the cavity; it also includes: an inner rod 7 slidably installed inside the cavity, a motor set inside the inner rod 7, a conveying wheel 8 keyed to the output end of the motor; a positioning rod 9 installed at the top of the inner rod 7, a test plate 10 installed at the top of the positioning rod 9; and a lifting component for adjusting the detection component, the installation base plate 1 is set to limit the fan-shaped platform 3, and the fan-shaped platform 3 can limit the monitoring range of the millimeter-wave radar body 17, so that the millimeter-wave radar body 17 can better obtain the measurement results. The arc-shaped limit seat 5 installed on the outer arc surface of the fan-shaped platform 3 can limit the inner rod 7. The motor inside the inner rod 7 can control the conveying wheel 8 to rotate in accordance with the inner wall of the inner slide groove 6, thereby controlling the inner rod 7 to move inside the arc-shaped limit seat 5. The positioning rod 9 at the top of the inner rod 7 limits the test plate 10. When the inner rod 7 moves with the rotation of the conveying wheel 8, the test plate 10 also moves with the inner rod 7 to change the position of the test plate 10 on the millimeter wave radar body 17, so as to better measure the sensitivity of the millimeter wave radar body 17 to monitoring flexibly moving objects.
[0038] Furthermore, the lifting assembly includes: two groups of L-shaped force plates 11 installed on the two end surfaces of the arc limit seat 5, and two groups of telescopic push rods 12 installed on the upper surface of the mounting base 1; the telescopic top end of the telescopic push rod 12 is fixedly connected to the L-shaped force plate 11, and the L-shaped force plates 11 arranged at both ends of the arc limit seat 5 can be used in conjunction with the telescopic push rod 12 to control the use height of the arc limit seat 5, to meet the use position adjustment of the test plate 10 while also adjusting the use height of the test plate 10, which can better measure the measurement effect of the millimeter wave radar body 17 on flexible moving objects.
[0039] Furthermore, the moving component includes: a side baffle 13 fitted on the upper surface of the limit plate 2, a roller screw 14 rotatably installed inside the side baffle 13, and a sliding plate 15 linked to the outside of the roller screw 14; the control end of the roller screw 14 is located inside the fan-shaped platform 3, and the outer arc surface of the sliding plate 15 is fitted on the inner wall of the side baffle 13 for sliding. The set limit plate 2 and the side baffle 13 on the upper part of the limit plate 2 limit the movement of the sliding plate 15, and the set roller screw 14 works so that the sliding plate 15 can move with the roller screw 14 as the center, so as to adjust the position of the millimeter wave radar body 17 on the fan-shaped platform 3.
[0040] It is worth noting that the millimeter-wave radar control component includes: an electric push rod 16 installed on the top of the sliding plate 15, a limit seat 28 rotatably installed on the telescopic top of the electric push rod 16, a control motor 29 installed inside the limit seat 28, and a mounting plate 30 key-connected and mounted on the top of the control motor 29; and a millimeter-wave radar body 17 for testing installed on the upper part of the mounting plate 30. The electric push rod 16 installed on the top of the sliding plate 15 controls the use height of the millimeter-wave radar body 17, so that the millimeter-wave radar body 17 itself has adjustability. After the roller screw 14 controls the electric push rod 16 to fit the inner wall of the arc groove 4, the control motor 29 can control the mounting plate 30 to rotate in a small range to further adjust the use angle of the millimeter-wave radar body 17, so that after the use angle of the millimeter-wave radar body 17 becomes clear, the test board 10 and the monitoring probe 21 are detected.
[0041] Specifically, the millimeter-wave radar body 17 is slidably installed inside the test frame 18, and the two groups of rotating baffles 19 are respectively arranged to rotate in accordance with the two groups of inclined surfaces of the fan-shaped table 3. Each group of rotating baffles 19 is provided with several groups of mounting holes 20, and the test components are positioned corresponding to each group of mounting holes 20. The set test frame 18 can limit the use path of the millimeter-wave radar body 17, test the straight-line detection distance of the millimeter-wave radar body 17, and prompt the detection stability through the influence of the test frame 18 on the millimeter-wave radar body 17. The two groups of rotating baffles 19 can cooperate with the test frame 18 to affect the detection range of the millimeter-wave radar body 17, so that the millimeter-wave radar body 17 can obtain better detection data within the specified position.
[0042] In addition, the test component includes: a monitoring probe 21 that is plugged into and installed in the mounting hole 20, an indicator light 22 at the end of the monitoring probe 21 that is telecommunication-connected; and an object to be detected that is arranged at the front end of the monitoring probe 21. The mounting hole 20 opened inside the rotating baffle 19 limits the monitoring probe 21. The monitoring probe 21 can be pushed out manually. The indicator light 22 electrically connected to the rear side of the monitoring probe 21 can display the usage status of the monitoring probe 21. When the monitoring probe 21 is captured by the millimeter-wave radar body 17, the indicator light 22 is on until the monitoring probe 21 rotates when the rotating baffle 19 is out of the detection range of the millimeter-wave radar body 17, and the indicator light 22 is turned off.
[0043] It is worth noting that the linkage assembly includes: an installation box 23 that is fitted on the top of the test frame 18, a motor 24 installed on the upper part of the installation box 23, a main gear 25 key-connected and installed at the output end of the motor 24, two sets of auxiliary gears 26 rotatably installed inside the installation box 23, and a connecting shaft 27 fixedly installed at the bottom of the auxiliary gear 26. The installation box 23 at the top of the test frame 18 can limit the main gear 25 and the auxiliary gear 26, making the main gear 25 and the auxiliary gear 26 more stable to use, thereby ensuring that the two sets of rotating baffles 19 can be controlled to rotate after the motor 24 works.
[0044] Specifically, the main gear 25 and the two sets of auxiliary gears 26 are all arranged inside the installation box 23. The main gear 25 is meshed with the two sets of auxiliary gears 26. The two sets of connecting shafts 27 are respectively fixedly connected to a set of rotating baffles 19. The auxiliary gears 26 of the main gear 25 are rotatably installed inside the installation box 23. Since the connecting shaft 27 set at the bottom of the auxiliary gear 26 is connected to the rotating baffle 19, the use angle of the rotating baffle 19 can be better controlled, thereby ensuring the control of the use position of the monitoring probe 21.
[0045] Based on the above-mentioned millimeter-wave radar testing device, this embodiment further discloses a testing method for the millimeter-wave radar testing device, including the following steps:
[0046] S1. The roller screw 14 is used to control the movement of the sliding plate 15, so that the use positions of the electric push rod 16 and the millimeter-wave radar body 17 are adjusted, and the use position of the millimeter-wave radar body 17 relative to the sector platform 3 is changed, so that the millimeter-wave radar body 17 can measure the sensitivity to the same obstacle at different positions, and the height of the millimeter-wave radar body 17 is controlled by the electric push rod 16 to measure the detection effect of different obstacles in different vertical directions.
[0047] S1. Control the roller screw 14 to move so that the electric push rod 16 fits into the arc groove 4 to fix the use position of the millimeter-wave radar body 17. Then, control the motor 29 to change the angle of the millimeter-wave radar body 17 to measure the detection effect of the millimeter-wave radar body 17 against the same obstacle at different angles.
[0048] S1. The internal motor of the inner rod 7 controls the rotation of the conveying wheel 8, so that the test plate 10 can reciprocate around the fan-shaped platform 3 along with the arc-shaped limit seat 5, so that the millimeter-wave radar body 17 can be fixed in a position to perform sensitivity testing on fast-moving objects. At the same time, the arc-shaped limit seat 5 can be raised and lowered by the telescopic push rod 12 to change the moving height of the test plate 10, thereby providing different ranges of test conditions for the millimeter-wave radar body 17 in the sensitivity test of the millimeter-wave radar body 17, so that the millimeter-wave radar body 17 can measure detection data more accurately.
[0049] S1. The motor 24 is used to control the rotation of the main gear 25, thereby driving the two sets of connecting shafts 27 to rotate, so that the two sets of rotating baffles 19 that are in contact with the outer surface of the sector-shaped platform 3 are opened and closed, thereby changing the control of the use angle of the monitoring probe 21, and then testing the monitoring range of the millimeter-wave radar body 17 when the position of the millimeter-wave radar body 17 is fixed. After measuring the maximum detection range of the millimeter-wave radar body 17, the monitoring probe 21 is randomly controlled to extend to test the detection sensitivity of the millimeter-wave radar body 17 under the extreme range.
