Description

Technical Field

[0001] The invention belongs to the technical field of radar antenna testing, in particular to an automatic testing device for radar antenna operation. Background Art

[0002] Radar is a device used to radiate and receive electromagnetic waves and determine the direction of detection. When transmitting, the radar must concentrate the energy to radiate in the direction required; when receiving, it should only receive the echo in the detection direction as much as possible, and distinguish the azimuth and elevation of the target, or one of the two. Among the three coordinates (azimuth, elevation and distance) of the target position measured by radar, the measurement of two coordinates (azimuth and elevation) is directly related to the performance of the antenna. Therefore, antenna performance is more important for radar equipment than for other electronic equipment such as communication equipment.

[0003] The angle of the radar antenna has a significant impact on the measurement accuracy. When selecting and installing a radar, factors such as antenna angle, signal transmission and reception characteristics, resolution, and environmental adaptability need to be considered comprehensively to ensure that the device can provide the best performance in a specific application environment.

[0004] The existing ground structure of radar antennas is easily affected by wind and sun, which may cause damage and affect the normal reception of signals. In addition, during the operation of the radar antenna, the angle between the radar antenna and the ground affects the stability of the received signal. During the initial installation, after the radar antenna is adjusted to a good working angle, it may become skewed due to external forces such as strong winds after running for a period of time, and the angle of the radar antenna needs to be recalibrated.

[0005] The existing test of the support part of the radar antenna above the ground generally involves sending test personnel to climb to the top of the radar antenna to observe whether there is any damage on the surface and record the location. At the same time, the test personnel need to come to the top of the radar antenna to place an angle test sensor, and cooperate with the remote measurement equipment on the ground outside to achieve multiple measurements of the radar antenna inclination, reduce measurement errors, and provide data support for the subsequent maintenance work of calibrating the radar antenna inclination. In this process, for radar antennas with a large height, it is inconvenient for test personnel to go up and down, and it is very dangerous, which affects the efficiency of the test work.

DETAILED DESCRIPTION

[0040] 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.

[0041] Embodiment 1:

[0042] In order to effectively solve the above problems, as shown in the accompanying drawings of the specification Figure 1-Figure 5 As shown, a radar antenna operation automatic test device includes a data acquisition component and a test data analysis center. The test data analysis center is used to analyze and process the radar antenna surface image data and inclination data collected by the data acquisition component and output the test results. The characteristics are:

[0043] The data acquisition component includes a fixed support 1, a movable slide rail 2 is arranged on the top of the fixed support 1, a test support seat 3 is slidably arranged on the movable slide rail 2, fixed image acquisition devices 34 are mounted on both sides of the test support seat 3, and a test support arm 31 is rotatably arranged at the bottom of the test support seat 3, and a rotating device is arranged at the rotating connection part of the test support arm 31. The rotating device can be a rotating motor and is controlled by an external controller to drive the test support arm 31 to rotate relative to the test support arm 31;

[0044] A mobile image acquisition device 32, an inclination test device 33 and a wireless transmitter are provided at the end of the test support arm 31. The wireless transmitter is used to transmit the data collected by the mobile image acquisition device 32, the inclination test device 33 and the fixed image acquisition device 34 to the test data analysis center.

[0045] Specific workflow: The existing ground structure of the radar antenna is easily affected by wind and sun, which may cause damage and affect the normal reception of signals. In addition, during the operation of the radar antenna, the angle between the radar antenna and the ground affects the stability of the received signal. During the initial installation, after the radar antenna is adjusted to a good working angle, it may become skewed due to external forces such as strong winds after running for a period of time, and the angle of the radar antenna needs to be recalibrated.

[0046] The existing test of the support part of the radar antenna above the ground generally involves sending testers to climb to the top of the radar antenna to observe whether the surface is damaged and record the location. At the same time, the testers need to go to the top of the radar antenna to place an angle test sensor, and cooperate with the remote measurement equipment on the ground outside to achieve multiple measurements of the radar antenna inclination, reduce measurement errors, and provide data support for the later maintenance work of calibrating the radar antenna inclination. In this process, for radar antennas with a large height, it is inconvenient for testers to go up and down, and there is a great risk, which affects the efficiency of the test work.

[0047] In view of the above problems, in order to facilitate the test of the test personnel, the present application pre-arranges the fixed support 1 in the area around the radar antenna. When a scheduled maintenance test is required, a movable slide rail 2 is erected on the fixed support 1. The height of the movable slide rail 2 is adapted to the height of the radar antenna as the test object. The height of the movable slide rail 2 after erection is preferably higher than the height of the radar antenna; the test support seat 3 is installed on the movable slide rail 2, because the test support seat 3 is slidably connected to the movable slide rail 2 through a slider, and the sliding connection method can be selected from the existing electric slider and electric slide rail matching method. Under the action of an external controller, the test support seat 3 is controlled to slide upward along the movable slide rail 2;

[0048] During the slow sliding process, fixed image acquisition devices 34 are arranged on both sides of the test support seat 3, and existing image acquisition industrial cameras and other equipment can be selected. As the test support seat 3 slides vertically upward and the radar antenna rotates automatically, the conditions of various parts of the surface of the radar antenna are fully photographed, and the image data are fed back to the test data analysis center, and the image data is analyzed to identify the parts that may be damaged. At the same time, existing engineering test tilt angle instruments, such as optical tilt instruments, can also be carried on both sides of the test support seat 3, and the tilt angle of the radar antenna and the ground can be automatically measured in conjunction with the reference objects set on the ground around the radar antenna.

[0049] Furthermore, in order to conduct a more in-depth and accurate test on the radar antenna, the rotating device is started to rotate the test support arm 31 that was originally kept vertical, and transform it from a vertical state to a horizontal state, so that the mobile image acquisition device 32 and the inclination test device 33 arranged on the end of the test support arm 31 are closer to the surface of the radar antenna, and can even penetrate into the gap position of the radar antenna components, and collect the image data of the radar antenna surface at a close distance, so as to better identify the detailed position points of the gap part of the radar antenna, so that the test of the surface condition of the radar antenna is more accurate and in-depth;

[0050] The inclination test device 33 on the end of the test support arm 31 can be equipped with a wireless inclination sensor. As the test support arm 31 moves to the test point on the top of the radar antenna, the inclination test device 33 that should have been placed manually by the maintenance personnel can be automatically placed by the test support arm 31, which reduces manpower consumption and more safely measures the installation inclination of the radar antenna to be tested. After the wireless inclination sensor on the inclination test device 33 contacts the top of the radar antenna, the inclination of the radar antenna at this time is tested and compared with the inclination calculated during the initial installation process. The data obtained by the above calculations are transmitted to the test data analysis center through a wireless transmitter to analyze the changes in the inclination of the radar antenna caused by the external environment during operation, and the damage defects identified in the comprehensive image data are fed back to the maintenance personnel, and data support is provided for formulating maintenance plans to ensure the normal operation of the radar antenna.

[0051] Embodiment 2:

[0052] On the basis of the first embodiment, there are many possible technical solutions for the test support arm 31 of the present application, for example, an existing intelligent mechanical arm with multiple movable joints can be selected, so that flexible adjustment at multiple angles can be performed, which is suitable for radar antennas with complex structures, and conveniently guides the mobile image acquisition device 32 to deeply collect image data of various parts of the radar antenna, thereby improving the accuracy of the test;

[0053] For a simple radar antenna structure, a rod-shaped structure with a simple structure and convenient maintenance can be selected. The overall rod-shaped structure of the test support arm 31 specifically includes a plurality of support rods 311, and a telescopic device 312 is arranged between the support rods 311. The telescopic device 312 uses an existing electric telescopic rod device and is controlled by an external controller. The telescopic device 312 is used to adjust the length of the test support arm 31.

[0054] The test support seat 3 is a square ring structure, and an electric slider is provided on the inner wall to be slidably connected with the movable slide rail 2 to realize the vertical movement of the test support seat 3; the test support arm 31 is located on one side of the test support seat 3, and a counterweight arm 4 is symmetrically provided on the other side of the test support seat 3;

[0055] A mounting seat 35 is provided at the end of the test support seat 3, and a positioning groove 351 is provided on the mounting seat 35. The mobile image acquisition device 32 is rotatably arranged on the inner wall of the positioning groove 351, and the mobile image acquisition device 32 includes a stabilizing seat 321. The stabilizing seat 321 is a cylindrical structure, and the two side ends of the stabilizing seat 321 are rotatably connected to the inner wall of the positioning groove 351 through a rotating shaft. A driving motor is provided at the rotating connection part to drive the stabilizing seat 321 to rotate slowly, and the driving motor is controlled by an external controller;

[0056] The arc surface of the stable seat 321 is evenly provided with mounting grooves 322, and a test camera 323 is installed inside the mounting groove 322; the outer side of the stable seat 321 is wrapped with a protective cover 324 of a transparent material, and the protective cover 324 is a cylindrical structure;

[0057] Specific workflow: Based on the specific workflow in Example 1, when the test support arm 31 rotates to a horizontal position, due to the weight of the test support arm 31 itself and the weight of various test equipment on the end, the center of gravity of the moving slide 2 as a whole becomes skewed. In order to ensure the stability of the moving slide 2, a counterweight arm 4 is provided on the test support seat 3 at a symmetrical position relative to the test support arm 31. The structure of the counterweight arm 4 is the same as that of the test support arm 31, and the weight of the counterweight block provided at the end of the counterweight arm 4 is equal to the weight of the test equipment such as the mobile image acquisition device 32 used for testing on the end of the test support arm 31; thus, when the test support arm 31 on one side rotates to a horizontal position and performs various test operations, the counterweight arm 4 on the other side is started at the same time and moves synchronously relative to the moving slide 2 in the middle, so that the test support arms 31 and the counterweight arms 4 on both sides of the moving slide 2 simultaneously perform mirror-symmetrical operation deformation, so that the center of gravity of the moving slide 2 as a whole returns to the middle position, effectively balancing the problem of the instability of the center of gravity of the moving slide 2 caused by the operation of the test support arm 31;

[0058] Furthermore, the mobile image acquisition device 32 arranged at the end of the test support arm 31 includes a mounting seat 35 and a stabilizing seat 321, and the test camera 323 is located on the outer surface of the stabilizing seat 321 and is distributed in an annular manner, and the stabilizing seat 321 is rotatably connected to the mounting seat 35 and is controlled by a driving motor at the rotatable connection portion; thus, as the end of the test support arm 31 moves, the test camera 323 located on the end mounting seat 35 moves, and the annularly distributed test camera 323 passes through the outlet of the positioning slot 351 to collect image data of the radar antenna surface from multiple angles, thereby making the test work proceed more smoothly;

[0059] In addition, a cylindrical protective cover 324 is provided on the outer side of the mounting seat 35 to cover and protect the multiple test cameras 323 distributed in a ring on the mounting seat 35. The test camera 323 can normally pass through the transparent protective cover 324 to perform image acquisition operations, and the protective cover 324 can prevent external dust and impurities from affecting the test camera 323. Moreover, as the test support arm 31 moves, the protective cover 324 can also prevent external radar antenna components from impacting and damaging the test camera 323 on the mounting seat 35 when a collision accident occurs due to improper operation, thereby better protecting the middle test camera 323 to be able to operate normally, thereby ensuring the normal operation of the radar antenna test work.

[0060] Embodiment three:

[0061] On the basis of the second embodiment, the clearance area between the inner wall of the positioning groove 351 and the protective cover 324 forms a purification area 36, ​​and the cross section of the purification area 36 is arc-shaped; inside the purification area 36, ​​cleaning blocks 361 are evenly arranged on the inner wall surface of the positioning groove 351, and bristles are evenly distributed on the conical end of the cleaning block 361 close to the surface of the protective cover 324;

[0062] Specific workflow: Based on the specific workflow in Example 2, the purification zone 36 is formed in the gap area between the inner wall of the positioning groove 351 and the protective cover 324. During the test, when the test support arm 31 penetrates deeply into the radar antenna, dust and debris such as spider webs on the surface of the radar antenna may adhere to the outer surface of the protective cover 324, which affects the normal shooting of the test camera 323 through the protective cover 324, thereby causing the collected image to be not clear enough, affecting the accuracy of the test; therefore, the purification zone 36 is set, and after dust and debris adhere to the part of the protective cover 324 corresponding to the opening of the positioning groove 351, the mounting seat 35 is rotated to drive the part of the protective cover 324 where the debris adheres to rotate to the inside of the purification zone 36, so that the clean part originally located on the surface of the purification zone 36 rotates to the opening of the positioning groove 351 to perform the test work normally;

[0063] As the protective cover 324 rotates, the end of the cleaning block 361 does not directly contact the outer surface of the protective cover 324, and a gap of 3-5 mm is maintained between them. Only larger debris protrudes from the surface of the protective cover 324, and when the protective cover 324 overlaps with the cleaning block 361, it will be impacted by the cleaning block 361 and fall off, while smaller dust and debris will contact the bristles evenly arranged on the end of the cleaning block 361. The bristles here are made of soft bristles specially used for cleaning the surface of camera lenses. Therefore, during the contact between the bristles and the surface of the protective cover 324, the scraping action of the bristles takes away the dust and debris adhered to the surface of the protective cover 324, thereby ensuring the cleanliness of the surface of the protective cover 324, ensuring the clarity of the image taken by the test camera 323 inside the protective cover 324, and improving the accuracy of the test of the radar antenna.

[0064] Embodiment 4:

[0065] On the basis of the third embodiment, a flushing chamber 37 is provided in the inner wall of the positioning groove 351 at the top of the purification zone 36, and a flushing hole 371 is provided on the side wall of the flushing chamber 37 to communicate with the inside of the purification zone 36, and the flushing chamber 37 is communicated with the gas outlet end of the gas supply device;

[0066] A recovery chamber 38 is provided at the position of the inner wall of the positioning groove 351 at the bottom of the purification zone 36. The inner wall of the recovery chamber 38 is communicated with the inside of the purification zone 36 through the recovery hole 381, and the recovery chamber 38 is communicated with the air inlet end of the air supply device. A filter screen 382 is provided on the inner wall of the recovery chamber 38. The opening of the flushing hole 371 points to the direction close to the recovery chamber 38. A closing roller is provided at the top outlet position of the purification zone 36. The closing roller is rotatably connected to the inner wall of the purification zone 36, and the surface of the closing roller is in contact with the surface of the protective cover 324. The closing roller can prevent the airflow flowing out of the flushing hole 371 from flowing out from the top opening of the purification zone 36, ensuring that the airflow flowing out of the flushing hole 371 is fully guided to flow downward, flushing downward along the purification zone 36, thereby improving the utilization efficiency of the airflow.

[0067] Interception tubes 39 are evenly arranged at the opening of the positioning groove 351. The top of the interception tube 39 is communicated with the flushing chamber 37, and the bottom is communicated with the recovery chamber 38. Purification holes 391 are evenly arranged on the surface of the interception tube 39. The purification holes 391 are communicated with the inside of the interception tube 39.

[0068] Specific workflow: Based on the specific workflow in the third embodiment, in order to more fully clean the surface of the protective cover 324 that rotates into the purification zone 36, the air supply device is started to inflate the inside of the flushing chamber 37, so that the air pressure inside the flushing chamber 37 increases, and a part of the airflow flows out from the flushing hole 371 and then flows downward along the gap area of ​​the purification zone 36, and is sucked into the recovery hole 381 of the recovery chamber 38, and the dust and impurities in the inflowing air are removed by the filter 382, ​​and are sucked into the air inlet end of the exhaust device, so as to realize the internal circulation of the purified airflow;

[0069] During this process, the flow direction of the cleaning airflow flowing downward along the gap area of ​​the purification zone 36 is opposite to the rotation direction of the protective cover 324, so the contact and friction effect of the cleaning airflow on the surface of the protective cover 324 is strengthened, and the dust impurities adhering to the surface of the protective cover 324 can be more thoroughly removed, and then the separated dust impurities are enriched in the recovery chamber 38, so as to avoid the dust impurities cleaned up from adhering to the protective cover 324 again and affecting the cleaning effect of the cleaning cover, and also avoid the dust impurities cleaned up from accumulating in the purification zone 36 and affecting the smooth rotation of the protective cover 324;

[0070] Furthermore, part of the air filled in the flushing chamber 37 flows into the intercepting tube 39, and flows downward along the intercepting tube 39 into the recovery chamber 38, participating in the circulation of the cleaning airflow; in this process, the intercepting tube 39 is inflated and expanded with increasing strength, so that when the test support arm 31 collides with various components of the radar antenna due to operational errors, the intercepting tube 39 is located at the opening of the positioning groove 351 to protect the internal protective cover 324 and the test camera 323, thereby avoiding direct impact of the antenna components on the protective cover 324; and the elastic material and inflated intercepting tube 39 is deformed after being impacted and is accelerated to deflate through the purification hole 391, which, on the one hand, cushions the impact and reduces damage to the antenna components, and on the other hand, the purification hole 391 deflates the air at the opening of the positioning groove 351 to form an outward airflow, thereby preventing dust and debris generated during the impact from approaching the protective cover 324 or even adhering to the surface of the protective cover 324, thereby ensuring the normal operation of the internal test camera 323 of the protective cover 324.

[0071] Embodiment five:

[0072] On the basis of the fourth embodiment, regarding the specific implementation method of the air supply device to realize the self-circulation of the flowing air in the flushing chamber 37 and the recovery chamber 38, this embodiment provides a possible technical solution. Specifically, an air guide pipe 352 is arranged inside the positioning groove 351, and one end of the air guide pipe 352 is communicated with the flushing chamber 37, and the other end is communicated with the recovery chamber 38; the air supply device is located inside the air guide pipe 352 near the flushing chamber 37, so that after the air supply device is started, the air in the recovery chamber 38 can be drawn into the flushing chamber 37 through the air guide pipe 352 and released, so as to realize the circulating flow;

[0073] The cleaning block 361 has a triangular cross section, and the cleaning block 361 is hollow inside to form a cleaning cavity 362, the cleaning cavity 362 extends to the conical end of the cleaning block 361 close to the protective cover 324 and forms an opening communicated with the outside, and a cleaning roller 363 is rotatably arranged at the opening, and the bristles on the conical end of the cleaning block 361 are distributed on the surface of the cleaning roller 363;

[0074] The cleaning chamber 362 is communicated with the air guide pipe 352 through the air extraction pipe 364. An adsorption layer is provided between the opening of the cleaning chamber 362 and the air extraction pipe 364. Therefore, when the air supply device is extracting air, the air extraction effect can also be extended to the inside of the cleaning chamber 362 through the air extraction pipe 364. However, because the inner diameter of the air extraction pipe 364 is small, the air extraction effect is smaller than the end of the air guide pipe 352 communicating with the recovery chamber 38. A control valve can also be provided to control the air flow of the air extraction pipe 364.

[0075] A micro motor may be provided at the rotation connection portion of the cleaning roller 363 to drive the cleaning roller 363 to rotate automatically, thereby achieving better cleaning of the surface of the protective cover 324;

[0076] Specific workflow: Based on the specific workflow in the fourth embodiment, the surfaces on both sides of the cleaning block 361 are inclined surfaces, so after the cleaning airflow flowing along the purification area 36 contacts the cleaning block 361, it flows along the inclined surface of the cleaning block 361 toward the surface of the protective cover 324, and then passes through the gap area between the surface of the protective cover 324 and the end of the cleaning block 361. Therefore, the gap area is relatively narrow, so the air flow rate is accelerated when passing through the gap area, and the impact on the surface of the protective cover 324 is strengthened, so that the impurities and dust adhering to the surface of the protective cover 324 are more fully taken away;

[0077] When the air flows through the gap area, it contacts the bristles arranged on the conical end of the cleaning block 361 and passes through the gap between the bristles. In this process, the cleaning airflow fully removes the dust and debris adhering to the surface of the gap between the bristles. Because the bristles are located on the cleaning roller 363 at the opening of the cleaning chamber 362, the tangential airflow impact at the gap can drive the cleaning roller 363 to rotate. At the same time, part of the airflow will flow into the cleaning chamber 362 through the gap between the cleaning roller 363 and the opening of the cleaning chamber 362, pass through the adsorption layer, enter the exhaust pipe 364, and converge into the air guide pipe 352.

[0078] During this process, as the cleaning roller 363 rotates, the dust and debris that are detached from the surface of the protective cover 324 scraped by the bristles on the cleaning roller 363 can flow into the cleaning chamber 362 nearby with the inhaled airflow, and be intercepted and collected by the adsorption layer; at the same time, after the bristles on the cleaning roller 363 rotate into the cleaning chamber 362, the airflow flushes so that the dust and debris adhered to the bristles that rotate into the cleaning chamber 362 can flow into the cleaning chamber 362 more fully and be collected; in this way, through the action of the cleaning chamber 362 and the cleaning roller 363, the dust and debris that fall from the area near the cleaning block 361 on the protective cover 324 can be sucked into the cleaning chamber 362 nearby and collected, ensuring that the bristles on the cleaning roller 363 are cleaned in time and can work normally, while better recovering the dust and debris on the protective cover 324, avoiding the fallen dust and debris from continuously flowing in the gap of the purification area 36 and causing wear and scratching on the surface of the protective cover 324, resulting in aggravated damage to the surface of the protective cover 324, affecting the transparency of the surface of the protective cover 324.

[0079] Embodiment six:

[0080] On the basis of Example 5, the adsorption layer includes a filter layer 365 arranged near the end of the exhaust pipe 364, and a through layer 366 arranged near the opening of the cleaning chamber 362, and the area between the filter layer 365 and the through layer 366 forms an adsorption area, and the adsorption area is filled with an adsorption sheet 368; the cross-section of the adsorption sheet 368 presents a continuous curved shape, and the two side ends of the adsorption sheet 368 are respectively connected to the through layer 366 and the filter layer 365 on both sides.

[0081] Specific workflow: On the basis of the specific workflow in Example 5, the specific structure of the adsorption layer can be composed of a double-layer structure consisting of a filter layer 365 and a through layer 366 and an adsorption area in the gap between them. The filter layer 365 and the through layer 366 are both elastic mesh structures, and the mesh number of the filter layer 365 is larger than that of the through layer 366. Therefore, a part of the larger dust and debris in the air is intercepted by the through layer 366, while the smaller dust flows into the adsorption area and contacts with the adsorption sheet 368 inside the adsorption area. The adsorption sheet 368 is made of chemical fiber and has a continuous wavy structure. When the air flows in the gap between the continuously curved adsorption sheets 368, the flow path and residence time are extended, so that the dust and impurities in the air are fully absorbed by the adsorption sheets 368, thereby improving the adsorption effect of the adsorption layer on the dust flowing into the air;

[0082] And because the adsorption sheets 368 are evenly arranged inside the adsorption area, the contact adsorption area for dust is increased, so that the adsorption layer can adsorb and retain more dust impurities, increase the continuous working time, make the dust and debris inside the purification area 36 receive a more sufficient impact, and reduce the wear and scratch on the surface of the protective cover 324.

[0086] Specific work flow: On the basis of the specific work flow in the sixth embodiment, in order to better clean the bristles, a tidying rod 369 is provided on the outer surface of the passing layer 366. When the cleaning roller 363 rotates under the scouring of the tangential airflow, the bristles on the surface of the cleaning roller 363 contact with the end of the tidying rod 369. The end of the tidying rod 369 passes through the bristle gap, and the bristles also pass through the tidying groove 5 at the end of the tidying rod 369, so that the bristles and the tidying groove 5 are interlocked with each other, so that the combing effect on the bristles can make the bristles be arranged, reduce the bending and twisting of the bristles, and The dust and debris adhered to the bristles are fully removed to ensure its normal operation; and when the dredging blocks 367 evenly arranged on the cleaning roller 363 coincide with the end of the tidying rod 369, the end of the dredging block 367 is embedded in the tidying groove 5 at the end of the tidying rod 369, and the debris embedded in the tidying groove 5 is removed to ensure its normal operation; and the friction between the tidying rod 369 and the bristles drives the through layer 366 connected to the tidying rod 369 to vibrate, thereby accelerating the shedding of debris embedded in the filter holes on the through layer 366, and reducing the adverse effects on the through layer 366.
