Description

Technical Field

[0001] This invention relates to the field of millimeter-wave radar simulator technology, specifically to a millimeter-wave radar simulator and its calibration and verification method. Background Technology

[0002] Radar simulators are being used more and more widely in autonomous driving assistance systems in open-pit coal mines. Typical driver assistance systems, such as adaptive cruise control, emergency braking, and lane change assist, mainly rely on millimeter-wave radar as an environmental perception sensor.

[0003] Existing methods for storing electricity using solar panels via simulators have the following drawbacks: Due to the high dust levels in coal mines, current technologies clean solar panels using rubber rollers and water. The cleaning process relies on friction between the rubber rollers and the glass panel, combined with water. However, rubber rollers are made of soft material, and when they encounter hard scale, they remain difficult to clean. This cleaning efficiency is unsatisfactory, and over time, excessive scale buildup may reduce the solar energy absorption rate. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a millimeter-wave radar simulator and its calibration and verification method, which can effectively solve the problems of hard scale being difficult to clean and the scale still entering the glass plate after cleaning, affecting the solar energy reception effect.

[0011] Preferably, the assembly includes mounting blocks installed on top of the absorbent cotton. Limiting grooves are formed on opposite sides of the two mounting blocks. L-shaped pressure blocks are slidably connected to the front and rear ends of the limiting grooves via slide rails. A storage groove is formed in the end of the L-shaped pressure block closest to the absorbent cotton. A first return spring is installed in the storage groove. A locking block, fixedly connected to the first return spring, is installed in the storage groove on the side away from the L-shaped pressure block. The locking block has a conical structure. A pressure groove matching the locking block is formed on the side of the mounting block corresponding to the locking block. Multiple magnets are spaced apart on the top of the absorbent cotton. A magnet plate that attracts the magnets is installed on the inner side of the cleaning plate.

[0012] Preferably, the intermittent reciprocating assembly includes two limiting plates.

[0014] Preferably, the brush tubes between the top movable seat and the bottom movable seat are not on the same vertical plane as the solar panel, and the upper half of the brush tube is detached from the outside of the support plate.

[0015] The present invention also provides a method for calibrating and verifying a millimeter-wave radar simulator, the method comprising the following steps: The user-input dynamic target information is sent to the millimeter-wave radar simulator so that the simulator can simulate the dynamic target based on the dynamic target information and control the water pump box to clean the solar panels in preparation for the simulator to work. The dynamic target information includes the actual speed of the dynamic target and the distance between the dynamic target and the real millimeter-wave radar. The system receives the test speed obtained from scanning a dynamic target using a real millimeter-wave radar and determines the speed difference between the test speed and the real speed. If the difference is within a set threshold range, the manual calibration verification passes. If it is not within the threshold range, the system re-executes the manual calibration adjustment strategy based on the preset value until the difference is within the threshold range.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a moving component to drive the tilted brush cylinder to rotate. The cleaning component uses the kinetic energy of the moving component to remove dirt. Then, the brush cylinder rolls, and water is sprayed from the nozzle of the water pump box, making the solar panel cleaner. Compared with the prior art, this invention can complete the cleaning of the solar panel in one movement without resetting the brush cylinder. Moreover, with the action of the intermittent reciprocating component, the brush cylinder moves up and down rapidly, further improving the cleaning effect. The invention also adjusts the force of the tilted hanging plate through the adjustment component. The linkage component can drive the entire tilted hanging plate to press the solar panel, which is more conducive to removing dirt. In addition, with the cooperation of the moving component, dust on the solar panel can also be cleaned. After cleaning with the brush tube, the scale on the brush tube will slide off to the outside along its axis, avoiding contact between the solar panel and the scale. Moreover, the brush tube will not slide the scale onto the solar panel regardless of whether it is on the left or right. The invention also includes absorbent cotton, which, with the cooperation of the moving component and the scale removal component, can absorb the residual moisture on the solar panel and prevent it from affecting the solar panel's receiving effect. This invention also facilitates the quick installation and disassembly of the absorbent material by setting up assembly components. The invention features a first air inlet groove that is horizontal and a second air inlet groove that is inclined along the top of the inclined mounting plate. This prevents water from the nozzle and rainwater from entering the absorbent cotton and causing it to become wet again, thus keeping the absorbent cotton dry. When the brush cylinder is at the leftmost and rightmost ends, the absorbent cotton can contact the outside air, facilitating rapid drying. The inclined mounting plate has a V-shaped structure, allowing removed impurities to slide off the inclined mounting plate during left and right movements, preventing impurities from entering through the gap between the solar panel and the inclined mounting plate. The invention also features an inclined mounting plate that abuts against the outside of the absorbent cotton, ensuring that the absorbent cotton remains unchanged during friction with the solar panel and preventing rainwater from wetting the absorbent cotton again.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: As Figure 1As shown, a millimeter-wave radar simulator includes a support frame 1. The radar simulator body is installed inside the support frame 1, and the radar simulator body is electrically connected to a solar panel 21. During use, the solar panel 21 supplies power to the radar simulator body. Simultaneously, the support frame 1 helps protect the radar simulator body and provides good power storage when used in remote areas. A battery is installed inside the support frame 1, and the solar panel 21 converts solar energy into electrical energy, which is stored in the battery for convenient use in remote areas, providing practicality. An inclined support plate 2 is installed on the top of the support frame 1, and the solar panel 21 is installed on the front end of the support plate 2. Movable seats 3 are located on the upper and lower sides of the left end of the support plate 2, with the top movable seat 3 positioned at the left end of the bottom movable seat 3. A brush cylinder 4 is arranged between the two movable seats 3. A micro motor that drives the brush cylinder 4 to rotate is installed on the upper movable seat 3 via a motor mount. A moving component 5 for driving the two movable seats 3 to move left and right is arranged on the top of the support plate 2. A descaling component 6 for cleaning the scale on the surface of the solar panel 21 is arranged at the left and right ends of the two movable seats 3. A water pump box 7 for providing water spray is installed on the upper movable seat 3. The water inlet of the water pump box 7 needs to be connected to an external water source to facilitate water output from the nozzle. Two nozzles located on the left and right sides of the brush cylinder 4 are installed at the bottom of the water pump box 7. An intermittent reciprocating component 8 for driving the brush cylinder 4 to move up and down along the solar panel 21 is arranged at the bottom of the solar panel 21. A cleaning component 9 for cleaning impurities on the brush cylinder 4 is arranged between the two movable seats 3.

[0021] During operation, when the moving component 5 drives the two moving seats 3 to move synchronously, the micro motor drives the brush cylinder 4 to rotate. The brush cylinder 4 rolls along the support plate 2 in an inclined manner. Dust and a small amount of scale on the solar panel 21 slide off the support plate 2 due to gravity. At the same time, during the movement of the brush cylinder 4, with the help of the descaling component 6, it is easier to clean the hard scale on the solar panel 21, making the brush cylinder 4 clean more smoothly. During the cleaning process, the nozzles on both sides of the water pump box 7 clean the solar panel 21, making the dirt on the solar panel 21 cleaner and improving the acceptance rate of the solar panel 21.

[0022] It is worth noting that the present invention does not require the brush cylinder 4 to be reset during the cleaning process of the solar panel 21, and the cleaning of the solar panel 21 can be completed in one move, resulting in high cleaning efficiency.

[0023] It is worth noting that when the brush cylinder 4 moves to the right, the nozzle on the right side of the water pump box 7 can wet the solar panel 21 and the brush for better cleaning. The nozzle on the left side of the water pump box 7 can perform a second cleaning on the cleaned solar panel 21, thereby improving the cleanliness of the solar panel 21.

[0024] Example 2: The technical solution is basically the same as that of Example 1, except that... Figure 1 As shown, the moving assembly 5 includes a motor 51 mounted on the top right end of the support plate 2. Moving slots 52 are provided at both the top and bottom ends of the support plate 2. The top moving slot 52 extends to the left, and the bottom moving slot 52 extends to the right. A first double-ended screw 53, which is driven by the output end of the motor 51, is rotatably connected within the top moving slot 52. A second double-ended screw 54 is rotatably connected within the bottom moving slot 52. Screw seats 55, which are rotatably connected to the first double-ended screw 53 and the second double-ended screw 54, are respectively installed on the upper left sidewall and the lower left and right sidewalls of the support plate 2. The movable seat 3 and the first double-ended screw 53, as well as the movable seat 3 and the second double-ended screw 54 located at the bottom, are rotatably connected by a rotating connector. The bottom wall of the movable groove 52 and the horizontal end of the screw seat 55 are both equipped with sliding rails that are slidably connected to the rotating connector. The left ends of the first double-ended screw 53 and the second double-ended screw 54 are rotatably passed through their corresponding screw seats 55 and are equipped with transmission wheels 56. The transmission wheels 56 are connected by a transmission belt 57. The brush cylinder 4 between the movable seat 3 at the top and the movable seat 3 at the bottom is inclined along the walking direction, and the upper half of the brush cylinder 4 is detached from the outside of the support plate 2.

[0025] During operation, the first double-headed screw 53 is driven to rotate by the drive motor 51. The second double-headed screw 54 is driven to move synchronously by the transmission wheel 56 and the transmission belt 57. With the cooperation of the first double-headed screw 53 and the second double-headed screw 54, the rotating connector moves left and right along the slide rail, thereby realizing the left and right movement of the moving seat 3 in an inclined manner.

[0026] It is worth noting that the brush cylinder 4, located between the top movable seat 3 and the bottom movable seat 3, is not on the same vertical plane as the solar panel 21. This is to prevent scale and impurities on the brush cylinder 4 from remaining on the support plate 2 and then sliding down the support plate 2 onto the solar panel 21, causing the solar panel 21 to come into contact with scale again. Furthermore, the upper half of the brush cylinder 4 is detached from the outside of the support plate 2 to allow the brush cylinder 4 to be positioned closer to the solar panel 21 to dry in time, preventing scale on its upper half from sliding down the support plate 2 onto the solar panel 21.

[0027] Example 3: The technical solution is basically the same as that of Example 1, except that... Figures 2-5As shown, the descaling assembly 6 includes mounting bases 61 installed at the left and right ends of the movable base 3. A support base 62 is installed between the upper and lower mounting bases 61. The support base 62 has a concave shape. A descaling plate 63 is provided at the bottom of the support base 62. The descaling plate 63 has a concave shape with the opening facing downwards. A linear array of spring telescopic rods 66 is slidably connected through the upper part of the support base 62. A connecting plate 67 is installed on the top of the multiple spring telescopic rods 66. The bottom of the descaling plate 63 is provided with absorbent cotton 622 for absorbing moisture from the solar panel 21. An adjustment assembly for adjusting the force of the descaling plate 63 is provided on the support base 62. The adjustment assembly includes a lifting plate 64 slidably connected to the inner cavity of the support base 62. Concave limiting seats 65 are installed at the upper and lower ends of the support base 62. The upper part is rotatably connected to two adjusting rods 68 threadedly connected to the lifting plate 64 via bearings. The top of the adjusting rods 68 slides through the connecting plate 67 and is installed with a first linkage wheel 69. Each set of first linkage wheels 69 is provided with a linkage assembly. The linkage assembly includes a first linkage belt 610 that is connected between the first linkage wheels 69 located at the upper and lower ends. A second linkage wheel 611 is installed on the top of the first linkage wheel 69 located at the bottom. A second linkage belt 612 is connected between the second linkage wheels 611 located at the left and right ends. A rocking plate 613 is installed on the top of the second linkage wheel 611 located at the left end. Inclined hanging plates 621 are installed on the left and right ends of the bottom of the cleaning plate 63. The two mounting seats 61 are arranged in a V-shape, and the two inclined hanging plates 621 abut against the outside of the absorbent cotton 622.

[0028] During operation, when the moving component 5 drives the descaling component 6 to move together, the two descaling plates 63 on the descaling component 6, in conjunction with the spring telescopic rod 66, can remove the dirt multiple times. The spring telescopic rod 66 reduces the impact of the descaling plates 63 on the protruding parts of the solar panel 21. The force of the descaling plates 63 on the solar panel 21 can be adjusted according to the different hardness of the scale. Specifically, the rotation of the rocker disc, in conjunction with the first linkage wheel 69, the first linkage belt 610, the second linkage wheel 611, and the second linkage belt 612, drives the entire adjusting rod 68 to rotate synchronously. This causes the lifting plate 64 to slide along the concave limit seat 65, compressing the spring in the spring telescopic rod 66, thus facilitating the adjustment of the force of the descaling plates 63 to remove scale of different hardness.

[0029] It is worth noting that after the solar panel 21 is cleaned, the water-absorbing cotton 622 can be placed against the solar panel 21 to absorb the residual moisture, preventing the residual moisture from affecting the photoelectric reception of the solar panel 21.

[0030] It is worth noting that the present invention sets the inclined hanging plate 621 into a figure-eight structure so that the removed impurities can slide down the inclined hanging plate 621 during the left and right movement of the inclined hanging plate 621, preventing the impurities from entering through the gap between the solar panel 21 and the inclined hanging plate 621. The present invention also sets the inclined hanging plate 621 to abut against the outside of the absorbent cotton 622 so that the absorbent cotton 622 remains unchanged during the friction with the solar panel 21, and also to prevent rainwater from wetting the absorbent cotton 622 again.

[0031] Example 4: The technical solution is basically the same as that of Example 1, except that... Figures 4-5 As shown, a first air inlet groove 641 is provided on the opposite side of the two inclined mounting plates 621 in a horizontally arranged manner. A second air inlet groove 642 is provided in the middle of the inclined mounting plate 621 along the top of the inclined mounting plate 621, and the second air inlet groove 642 is connected to the first air inlet groove 641. A third air inlet groove 643 in a rectangular array is provided between the opposite sides of the two inclined mounting plates 621, and the third air inlet groove 643 is connected to the second air inlet groove 642.

[0032] After the moisture on the solar panel 21 is absorbed by the absorbent cotton 622, in order to prevent the absorbent cotton 622 from becoming contaminated due to lack of air circulation inside the inclined mounting plate 621, the present invention uses the cooperation of the first air inlet groove 641, the second air inlet groove 642 and the third air inlet groove 643 to allow external air to enter the interior of the inclined mounting plate 621, thereby drying the moisture on the absorbent cotton 622 so that it can be used again next time.

[0033] It is worth noting that the present invention sets the first air inlet groove 641 to be horizontal and the second air inlet groove 642 to be inclined along the top of the inclined hanging plate 621 in order to prevent water and rainwater on the nozzle from entering the interior of the absorbent cotton 622 and causing the absorbent cotton 622 to become wet again.

[0034] Example 5: The technical solution is basically the same as that of Example 1, except that... Figures 5-6As shown, the cleaning plate 63 is equipped with an assembly component for quickly installing and removing the absorbent cotton 622. The assembly component includes a mounting block 631 installed on the top of the absorbent cotton 622. Limiting grooves 632 are opened on opposite sides of the two mounting blocks 631. L-shaped pressure blocks 633 are slidably connected to the front and rear ends of the limiting grooves 632 via slide rails. A storage groove is opened in the end of the L-shaped pressure block 633 near the absorbent cotton 622. A first return spring 635 is installed in the storage groove. A locking block 636 fixedly connected to the first return spring 635 is installed on the side of the storage groove away from the L-shaped pressure block 633. The locking block 636 has a conical structure. A pressure groove 634 matching the locking block 636 is opened on the side of the mounting block 631 corresponding to the locking block 636. Multiple magnet blocks 637 are installed at intervals on the top of the absorbent cotton 622. A magnet plate 638 that attracts the magnet blocks 637 is installed on the inner side of the cleaning plate 63.

[0035] During operation, when the absorbent cotton 622 needs to be replaced, remove any one of the L-shaped pressure blocks 633, and then use another L-shaped pressure block 633 to drive the mounting block 631 to slide along the limiting groove 632, so that the absorbent cotton 622 is detached from the cleaning plate 63. Similarly, when a new absorbent cotton 622 needs to be installed, insert any one of the pressure grooves 634 on the absorbent cotton 622 into the cleaning plate 63, and then insert the L-shaped pressure block 633 into the pressure groove 634. Then, slide it to the upper limit through the limiting groove 632. With the cooperation of the magnet plate 638 and the magnet block 637, it is easier to install and remove the absorbent cotton 622, improving its installation and removal efficiency. Moreover, when the absorbent cotton 622 moves on the solar panel 21, it makes the movement of the absorbent cotton 622 more stable.

[0036] Example 6: The technical solution is basically the same as that of Example 1, except that... Figure 1 and Figure 7 As shown, the intermittent reciprocating assembly 8 includes two limiting plates 81. One end of the two limiting plates 81 on opposite sides is limited and slidably positioned within the two ends of the brush cylinder 4. A slider 82 is installed on one end of the two limiting plates 81 on opposite sides. A movable limiting groove is provided in the two ends of the brush cylinder 4. A second return spring 83, which is fixedly connected to the slider 82, is installed in the movable limiting groove. A drive block 84 is installed at the bottom of the brush cylinder 4 and is slidably connected to the limiting plate 81 located at the bottom. A rotating block 85 is rotatably connected to the bottom of the drive block 84. A track plate 86 is installed on one side of the support plate 2 corresponding to the drive block 84. The track on the track plate 86 is slidably connected to the rotating block 85.

[0037] During operation, as the brush cylinder 4 moves, the rotating block 85 at the bottom of the drive block 84 slides on the track on the track plate 86. The drive block 84 moves up and down intermittently in a snake-like manner along the track plate 86, thereby causing the brush cylinder 4 to move up and down intermittently in sync. With the cooperation of the second return spring 83, the brush cylinder 4 moves up and down intermittently quickly from the surface of the sun plate 21, which helps to improve the cleaning efficiency of the brush cylinder 4 on the sun plate 21.

[0038] Example 7: The technical solution is basically the same as that of Example 1, except that... Figure 1 , Figure 3 and Figure 8 As shown, the cleaning assembly 9 includes a first gear 91 rotatably connected to a movable seat 3 located at the bottom. A second gear 92, which meshes with the first gear 91, is rotatably connected to the front end of the movable seat 3 located at the bottom. An auxiliary rod 93 is rotatably connected to the top of the two movable seats 3 located at the top of the brush cylinder 4. The bottom of the auxiliary rod 93 rotatably passes through the movable seat 3 and is fixedly connected to the second gear 92. Multiple sliding rings 94 are installed at intervals on the outer side of the auxiliary rod 93. Multiple hook plates 95 are installed in a circular array on the outer side of the sliding rings 94. A lever 96 along the axis of the auxiliary rod 93 is installed on the multiple hook plates 95. The hook plates 95 and the lever 96 abut against the brush of the brush cylinder 4.

[0039] During operation, when the brush cylinder 4 rotates, it drives the first gear 91 connected to it. Then, the first gear 91 drives the second gear 92 to rotate. As a result, the auxiliary rod 93 drives the sliding ring 94, hook plate 95 and lever 96 to rotate synchronously. With the cooperation of hook plate 95 and lever 96, the impurities and dust on the brush cylinder 4 are cleaned, keeping the brushes on the brush cylinder 4 clean and making the cleaning of the brush cylinder 4 more stable.

[0040] It is worth noting that, since the first gear 91 and the second gear 92 are meshed, the brush cylinder 4 and the auxiliary rod 93 rotate in opposite directions, thereby further improving the cleaning effect of the cleaning component 9.

[0041] The present invention also provides a method for calibrating and verifying a millimeter-wave radar simulator, the method comprising the following steps: The user-input dynamic target information is sent to the millimeter-wave radar simulator so that the simulator can simulate the dynamic target based on the dynamic target information and control the water pump box to clean the solar panels in preparation for the simulator to work. The dynamic target information includes the actual speed of the dynamic target and the distance between the dynamic target and the real millimeter-wave radar. The system receives the test speed obtained from scanning a dynamic target using a real millimeter-wave radar and determines the speed difference between the test speed and the real speed. If the difference is within a set threshold range, the manual calibration verification passes. If it is not within the threshold range, the system re-executes the manual calibration adjustment strategy based on the preset value until the difference is within the threshold range.

[0042] Working Principle: This device is used in millimeter-wave radar simulators. When dust needs to be cleaned from the solar panel 21, the driving moving component 5 moves the brush cylinder 4 to the right, simultaneously driving a micro motor to rotate the brush cylinder 4, thus cleaning the dust from the solar panel 21. The two nozzles on the water pump box 7 clean the solar panel 21, further refining the cleaning process. The cleaning component 6 further removes impurities from the brush cylinder 4, ensuring a cleaner brush cylinder 4 during the cleaning process. Furthermore, this invention utilizes an inclined... The solar panel 21 is cleaned by intermittent reciprocating component 8, which drives the brush cylinder 4 to move up and down intermittently along the solar panel 21 to further improve cleaning efficiency. When the brush cylinder 4 finishes moving, it stops on the right end of the support plate 2. The scale on the brush cylinder 4 slides down to the bottom of the brush cylinder 4 and falls onto the bottom surface. The cleaning operation of the solar panel 21 is completed in one movement. There is no need to reset the brush cylinder 4. When cleaning again, the above steps are repeated in the opposite direction to clean the solar panel 21. When the absorbent cotton 622 needs to be replaced, remove any one of the L-shaped pressure blocks 633, and then use another L-shaped pressure block 633 to drive the mounting block 631 to slide along the limiting groove 632, so that the absorbent cotton 622 is detached from the cleaning plate 63. Similarly, when a new absorbent cotton 622 needs to be installed, insert any one of the pressure grooves 634 on the absorbent cotton 622 into the cleaning plate 63, and then insert the L-shaped pressure block 633 into the pressure groove 634. Then slide it through the limiting groove 632. With the cooperation of the magnetic plate 638 and the magnetic block 637, it is easier to install and remove the absorbent cotton 622.
