Description

Technical Field

[0001] This utility model relates to the field of radar testing technology, and in particular to a radar testing system. Background Technology

[0002] Millimeter-wave radar is a radar system that uses the millimeter-wave band for detection and is commonly used in the automotive industry. The minimum detection range of millimeter-wave radar is one of the important indicators for evaluating the safety performance of this radar system. It ensures that the radar can detect obstacles at a sufficiently long distance, thus providing enough time for the vehicle's intelligent driving system or the driver to avoid them.

[0003] Although the minimum detection range of automotive millimeter-wave radar is theoretically known—that is, it can be obtained through the radar's design parameters and simulation calculations—in practical applications, considering actual operating conditions (such as environmental factors like temperature, humidity, rain, snow, and manufacturing errors), it is necessary to conduct actual tests on the minimum detection range of millimeter-wave radar.

[0004] Currently, the traditional testing method involves selecting a relatively open test site, having an operator manually place a detection target (such as a metal cone) in front of the automotive millimeter-wave radar, manually adjust the distance of the cone, observe the target status in the radar controller software, then manually measure the distance using tools such as a tape measure and laser rangefinder, and record the distance data and radar response for each measurement. Finally, the recorded data is compared and analyzed with the radar's theoretical performance to obtain the radar's actual minimum detection range.

[0005] However, this traditional testing method suffers from low stability due to manual operation, which easily introduces testing errors and results in low accuracy. Furthermore, since it is conducted in an open environment, it is easily affected by the surrounding environment, which in turn affects the test results and reliability. Utility Model Content

[0006] The purpose of this invention is to solve the technical problem of low testing accuracy in traditional radar minimum detection range testing methods. This invention provides a radar testing system that can automate the testing of radar minimum detection range without requiring manual adjustment of the cone position, thus offering better testing accuracy and reliability.

[0007] To address the aforementioned technical problems, this utility model discloses a radar testing system, comprising:

[0008] A first track extends along a first direction, wherein the first direction is a horizontal direction;

[0009] A first mounting part is used to mount a radar. The first mounting part extends along a second direction and is disposed on one side of the first track. The radar is disposed at the end of the first mounting part away from the first track. The second direction is orthogonal to the first direction.

[0010] A cone assembly includes a second mounting portion and a cone, the second mounting portion being slidably connected to the first track along the first direction, the cone being disposed at the end of the second mounting portion away from the first track, and the cone being used to receive and reflect signals from the radar.

[0011] A first controller is configured to control the radar's transmitted signals and / or to process the radar's signals reflected by the cone.

[0012] A second controller and a motor are electrically connected. The motor is connected to the first track. The second controller is used to control the motor to drive the second mounting part to slide along the first track.

[0013] A limiting device is provided on the first track and is used to restrict the movement of the second mounting part and the cone along the first direction and toward the first mounting part.

[0014] By adopting the above technical solution, the first mounting part for mounting the radar and the second mounting part for mounting the corner cone are respectively set on both sides of the first track along the first direction. The first controller is used to control the radar on the first mounting part to transmit signals or receive signals reflected by the corner cone. In this process, the second mounting part is connected to the first track in a slidable manner along the first direction, so that the corner cone on the second mounting part can move towards or away from the radar in the first direction to adjust the distance between the corner cone and the radar in the first direction. This realizes automatic testing of the minimum detection range of the radar without the need for operators to manually adjust the position of the corner cone, avoiding errors caused by manual adjustment and effectively improving the testing accuracy.

[0015] Meanwhile, a second controller and a motor control the movement of the second mounting part of the mounting cone on the first track. The second controller, motor (e.g., a servo motor), second mounting part, and first track constitute a controllable linear guide system, enabling high-precision adjustment of the distance between the cone on the second mounting part and the radar. Specifically, the second controller is electrically connected to the servo motor to control its clockwise or counterclockwise rotation. Simultaneously, the servo motor is connected to the first track, and the second mounting part is slidably connected to the first track. Thus, under the control of the second controller, the servo motor enables the first track to drive the second mounting part to move towards or away from the first mounting part (radar) along a first direction, thereby adjusting the distance between the second mounting part (cone) and the first mounting part (radar).

[0016] In addition, by setting (e.g., setting the sliding distance and sliding time of the second mounting part) and controlling the sliding of the second mounting part through the second controller, the traditional testing method of manually adjusting the cone distance by the operator can be replaced, which can effectively reduce the measurement time and improve the measurement efficiency.

[0017] Furthermore, the limiting device can limit the distance between the cone and the radar. On the one hand, it prevents the second mounting part and the cone, and the first mounting part and the radar from colliding, thereby effectively protecting the cone and the radar. On the other hand, since the minimum detection range of the radar is determined by the design parameters, the limiting device can ensure the optimal detection range and ensure that the radar can work within the designed performance range, thereby effectively improving the detection accuracy.

[0018] According to another specific embodiment of the present invention, the second mounting part includes a support part and a sliding part. The support part extends along the second direction, the cone is disposed at one end of the support part, and the sliding part is disposed at the other end of the support part. The first track includes a lead screw and a nut. The nut is sleeved on the outside of the lead screw and fixed inside the sliding part. The motor is used to drive the lead screw to rotate, so as to drive the nut and the sliding part to move along the first direction.

[0019] According to another specific embodiment of the present invention, the second mounting part includes a support part and a base. The support part extends along the second direction. The cone is disposed at one end of the support part, and the base is disposed at the other end of the support part. The first track includes a belt assembly. The belt assembly includes a pulley and a belt. The base is disposed on the belt. The motor is used to drive the pulley to rotate so as to drive the belt to move along the first direction.

[0020] According to another specific embodiment of the present invention, along the first direction, there is a first distance between the limiting device and the first mounting part, and the radar has a first detection range. Along the first direction, the first distance is not greater than the first detection range.

[0021] According to another specific embodiment of the present invention, the limiting device includes: a limit switch.

[0022] According to another specific embodiment of the present invention, the limit switch is electrically connected to the second controller, and the limit switch is used to switch between a first state and a second state.

[0023] In the first state, the second mounting part contacts the limit switch, and the limit switch sends an electrical signal to the second controller, so that the second controller sends a stop signal to the motor.

[0024] In the second state, the second mounting part is not in contact with the limit switch, and the second controller sends a sliding signal to the motor.

[0025] According to another specific embodiment of the present invention, the radar testing system further includes: an absorption wall, which is disposed on the side of the pyramidal assembly away from the first mounting portion along the first direction and spaced apart from the pyramidal assembly; the projection of the absorption wall along the second direction and the third direction is used to cover the pyramidal assembly; the second direction and the third direction intersect.

[0026] Using the above technical solution, interference signals from other sources may exist near the second mounting part where the corner cone is installed. By placing the absorbing wall on the side of the corner cone assembly away from the first mounting part, the absorbing wall can shield nearby interference signals, thereby ensuring that the radar on the first mounting part can only receive signals reflected from the corner cone and will not receive other interference signals. In other words, the absorbing wall can block interference signals from other sources, thus protecting the radar from external interference. Furthermore, when the radar on the first mounting part transmits signals relative to the corner cone, some energy may also irradiate the environment or objects near the second mounting part, generating interference signals. Therefore, the absorbing wall can also reduce the interference of the radar testing system to the external environment or objects.

[0027] On the other hand, the absorbing wall can also prevent objects near the pyramidal component from being irradiated by radar waves emitted by the radar, which would then bounce back and affect the test accuracy. In other words, the absorbing wall can avoid interference from objects near the pyramidal component. Therefore, the radar test system of this application embodiment can be set up not only in open environments (such as outdoors or relatively open test sites) but also in non-open environments (such as factory buildings), which has high applicability and high reliability.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] refer to Figure 1 This application provides a radar testing system 100, including: a first track 110, a radar device, a cone assembly 140, a first controller 105, a second controller 106, a motor (e.g., a servo motor 107), and a limit device 108.

[0038] like Figure 1 As shown, the first track 110 is along the first direction (e.g.) Figure 1 (as shown in the Y direction) extends. One side of the first track 110 (i.e. Figure 1 A radar device is installed on the side indicated by the Y2 direction.

[0039] As can be seen, the radar device includes a first mounting part 102 and a radar 103, with the first mounting part 102 along a second direction (e.g., Figure 1 Extending in the Z direction shown in the diagram, and located on one side of the first track 110 (i.e., Figure 1 (The side indicated by the Y2 direction); the radar 103 is mounted on the top of the first mounting part 102, that is, the radar 103 is mounted on the end of the first mounting part 102 away from the first track 110 (i.e., the side indicated by the Y2 direction); the radar 103 is mounted on the top of the first mounting part 102, that is, the radar 103 is mounted on the end of the first mounting part 102 away from the first track 110. Figure 1 (The end pointed to in the Z1 direction).

[0040] Meanwhile, on the other side of the first track 110 (i.e. Figure 1 A pyramidal assembly 140 is provided on the side indicated by the Y1 direction. The pyramidal assembly 140 includes a second mounting portion 141 and a pyramid 142. It can be seen that the second mounting portion 141 is also along the second direction (e.g., Figure 1 Extending in the Z direction shown in the diagram, the pyramid 142 is mounted on the top of the second mounting portion 141, that is, the pyramid 142 is mounted on the end of the second mounting portion 141 away from the first track 110 (i.e., Figure 1 (The end pointed to in the Z1 direction).

[0041] Furthermore, it can be seen that along the first direction (such as...) Figure 1The Y direction shown in the figure) and the second direction (as shown in the figure) Figure 1 (As shown in the Z direction), the radar 103 located on the first mounting part 102 and the cone 142 located on the second mounting part 141 are respectively arranged in a corresponding manner.

[0042] Continue to refer to Figure 1 The second mounting part 141 is along the first direction (e.g.) Figure 1 The second mounting portion 141 is slidably connected to the first track 110 in the Y direction shown in the diagram. In other words, the second mounting portion 141 can reciprocate along the first track 110, i.e., the second mounting portion 141 can move along the first direction and toward the first mounting portion 102 (e.g., in the Y direction). Figure 1 It can also move in the Y2 direction shown in the figure, and can also move in the first direction and away from the first mounting part 102 (such as...). Figure 1 (The movement is shown in the Y1 direction).

[0043] In this embodiment of the application, the first controller 105 described above can control the radar 103 to move towards the cone 142 (i.e., Figure 1 The radar 103 transmits a signal in the Y1 direction shown in the diagram. At the same time, the corner cone 142 (also called a corner reflector) reflects the signal to the radar 103. After receiving the reflected signal, the radar 103 transmits the reflected signal to the first controller 105. The first controller 105 processes (such as calculating and recording data) the reflected signal, for example, by calculating parameters such as the time difference, frequency, and amplitude of the signal, thereby obtaining the distance between the radar 103 and the corner cone 142.

[0044] Simultaneously, the first controller 105 is also capable of monitoring, recording, and evaluating measurement data. For example, the first controller 105 can display the calculated distance on a screen, such as... Figure 1 As shown, the first controller 105 displays a graphical coordinate system, through which the operator can observe the distance change trend between the radar 103 and the cone 142, so as to analyze the performance of the radar 103 in more depth and make necessary adjustments and optimizations.

[0045] Continue to refer to Figure 1 The second controller 106 and servo motor 107 are electrically connected. The servo motor 107 is connected to the first track 110. The second controller 106 controls the servo motor 107 to drive the second mounting part 141 to slide along the first track 110. Using this technical solution, the second controller 106 and servo motor 107 control the movement of the second mounting part 141 (which mounts the cone 142) on the first track 110. The second controller 106, servo motor 107, second mounting part 141, and first track 110 constitute a controllable linear guide rail system, thereby enabling high-precision adjustment of the distance between the cone 142 on the second mounting part 141 and the radar.

[0046] Specifically, the second controller 106 is electrically connected to the servo motor 107 to control the servo motor 107 to rotate clockwise or counterclockwise. At the same time, the servo motor 107 is connected to the first track 110, and the second mounting part 141 is slidably connected to the first track 110. Thus, under the control of the second controller 106, the servo motor 107 can cause the first track 110 to drive the second mounting part 141 to move toward or away from the first mounting part 102 (radar 103) in a first direction, so as to realize the distance adjustment between the second mounting part 141 (cone 142) and the first mounting part 102 (radar 103).

[0047] In addition, by setting (for example, setting the sliding distance and sliding time of the second mounting part 141) and controlling the sliding of the second mounting part 141 through the second controller 106, the traditional testing method of manually adjusting the distance of the cone 142 by the operator can be replaced, which can effectively reduce the measurement time and improve the measurement efficiency.

[0048] Continue to refer to Figure 1 The aforementioned limiting device 108 is disposed on the first track 110. The limiting device 108 is used to restrict the second mounting portion 141 and the cone 142 along the first direction and toward the first mounting portion 102 (i.e., Figure 1 (Movement in the Y2 direction shown in the figure).

[0049] Continue to refer to Figure 1 For example, the radar testing system 100 of this application embodiment further includes a power supply 1010 and a data center 1011. The power supply 1010 is electrically connected to the radar 103 on the first mounting section 102 and is used to supply power to the radar 103. The data center 1011 is electrically connected to the first controller 105 and is capable of storing measurement data monitored and recorded by the first controller 105.

[0050] By adopting the above technical solution, the first mounting part 102 for mounting radar 103 and the second mounting part 141 for mounting cone 142 are respectively set on both sides of the first track 110 along the first direction. The first controller 105 is used to control the radar 103 on the first mounting part 102 to transmit signals or receive signals reflected by the cone 142. In this process, the second mounting part 141 is connected to the first track in a slidable manner along the first direction, so that the cone 142 on the second mounting part 141 can move towards or away from the radar 103 in the first direction to adjust the distance between the cone 142 and the radar 103 in the first direction. This realizes the automatic testing of the minimum detection distance of the radar 103 without the need for operators to manually adjust the position of the cone 142, avoiding errors caused by manual adjustment and effectively improving the testing accuracy.

[0051] Meanwhile, the second controller 106 and the servo motor 107 are used to control the movement of the second mounting part 141 of the mounting pyramid 142 on the first track 110. The second controller 106, the servo motor 107, the second mounting part 141, and the first track 110 constitute a controllable linear guide system, thereby enabling high-precision adjustment of the distance between the pyramid 142 on the second mounting part 141 and the radar 103. Specifically, the second controller 106 is electrically connected to the servo motor 107 to control the servo motor 107 to rotate clockwise or counterclockwise. At the same time, the servo motor 107 is connected to the first track 110, and the second mounting part 141 is slidably connected to the first track 110. Thus, under the control of the second controller 106, the servo motor 107 can cause the first track 110 to drive the second mounting part 141 to move towards or away from the first mounting part 102 (radar 103) in a first direction, thereby realizing the adjustment of the distance between the second mounting part 141 (pyramid 142) and the first mounting part 102 (radar 103).

[0052] In addition, by setting (for example, setting the sliding distance and sliding time of the second mounting part 141) and controlling the sliding of the second mounting part 141 through the second controller 106, the traditional testing method of manually adjusting the distance of the cone 142 by the operator can be replaced, which can effectively reduce the measurement time and improve the measurement efficiency.

[0053] Furthermore, the limiting device 108 can limit the distance between the cone 142 and the radar 103. On the one hand, it prevents the second mounting part 141 and the cone 142, and the first mounting part 102 and the radar 103 from colliding, thereby effectively protecting the cone 142 and the radar 103. On the other hand, since the minimum detection distance of the radar 103 is determined by the design parameters, the limiting device 108 can ensure the optimal detection distance and ensure that the radar 103 can work within the designed performance range, thereby effectively improving the detection accuracy.

[0054] In some possible embodiments, the second mounting portion 141 includes a support portion 1411 and a sliding portion 1412, the support portion 1411 being along a second direction (e.g., Figure 1 Extending in the Z direction shown in the figure, a pyramid 142 is provided at one end of the support portion 1411 (i.e., Figure 1 The sliding part 1412 is located at the other end of the support part 1411 (i.e., the end pointed to in the Z1 direction). Figure 1 (The end pointed to in the Z2 direction).

[0055] like Figure 1 As shown, the first track 110 includes a lead screw 111 and a nut (not shown in the figure). It can be seen that the lead screw 111 moves along a first direction (e.g., ...). Figure 1Extending in the Y direction shown, the nut is sleeved on the outside of the lead screw 111 and fixed inside the sliding part 1412. The servo motor 107 can drive the lead screw 111 to rotate, so as to drive the nut and the sliding part 1412 to move along the first direction.

[0056] It should be noted that the lead screw 111 is in Figure 1 The illustration is for illustrative purposes only. Those skilled in the art will understand that the servo motor 107 can drive the lead screw 111 to rotate circumferentially and drive the nut sleeved on the outside of the lead screw 111 to move in the first direction, thereby driving the sliding part 1412 to move in the first direction.

[0057] In some other possible embodiments, the second mounting portion 141 includes a support portion 1411 and a base 1413, the support portion 1411 being along a second direction (e.g., Figure 1 Extending in the Z direction (as shown in the figure), a pyramid 142 is located at one end of the support 1411, and a base 1413 is located at the other end of the support 1411; the first track includes a belt assembly (not shown in the figure), which includes a pulley and a belt. The base 1413 is placed on the belt and remains stationary relative to the belt. The servo motor 107 can drive the pulley to rotate, thereby driving the belt along the first direction (as shown in the figure). Figure 1 The movement (in the Y direction shown in the figure) drives the second mounting part 141 to move along the first direction.

[0058] refer to Figure 1 In some possible implementations, the aforementioned limiting device 108 includes a limit switch 1081. It can be seen that along the first direction (e.g., Figure 1 (As shown in the Y direction), there is a first distance L between the limit switch 1081 and the first mounting part 102, that is, the distance between the mounting position of the limit switch 1081 and the first mounting part 102. It can be understood that the radar 103 has a preset first detection range, so along the first direction (e.g., the Y direction), the radar 103 has a first detection range. Figure 1 (as shown in the Y direction), the first distance L mentioned above should not be greater than the first detection range preset by the radar 103.

[0059] refer to Figure 1 and Figure 2 In some possible implementations, the limit switch 1081 is electrically connected to the second controller 106, and the limit switch 1081 is used in a first state (e.g. Figure 2 (as shown) and the second state (as shown) Figure 1 Switch between (as shown).

[0060] like Figure 2As shown, in the first state, the sliding part 1412 of the second mounting part 141 contacts the limit switch 1081. At this time, the limit switch 1081 sends an electrical signal to the second controller 106, thereby the second controller 106 sends a stop signal to the servo motor 107.

[0061] like Figure 1 As shown, in the second state, the second mounting part 141 is not in contact with the limit switch 1081, and the second controller 106 sends a sliding signal to the aforementioned servo motor 107.

[0062] refer to Figure 3 and combined Figure 1 and Figure 2 In some possible implementations, the radar testing system 100 further includes an absorption wall 109, which is disposed on the side of the pyramid assembly 140 away from the first mounting portion 102 along the first direction (i.e., Figure 1 The absorption wall 109 is located on the side indicated by the Y1 direction and is spaced apart from the pyramidal assembly 140; the absorption wall 109 is located in the second direction (e.g., the side indicated by the Y1 direction). Figure 1 The projections of the Z direction (shown in the figure) and the third direction (not shown in the figure, but the third direction intersects with the first direction and the second direction mentioned above, respectively) can cover the pyramid component 140.

[0063] Using the above technical solution, interference signals from other sources may exist near the second mounting portion 141 where the cone 142 is mounted. By placing the absorbing wall 109 on the side of the cone assembly 140 away from the first mounting portion 102, the absorbing wall 109 can shield nearby interference signals, thereby ensuring that the radar 103 on the first mounting portion 102 can only receive signals reflected from the cone 142 and will not receive other interference signals. That is, the absorbing wall 109 can block interference signals from other sources, thereby protecting the radar 103 from external interference. Furthermore, when the radar 103 on the first mounting portion 102 transmits signals relative to the cone 142, some energy may also irradiate the environment or objects near the second mounting portion 141, generating interference signals. Therefore, the absorbing wall 109 can also reduce the interference of the radar testing system 100 to the external environment or objects.

[0064] refer to Figure 1 and Figure 2 The radar testing system 100 of this application embodiment includes, but is not limited to, the following operation mode: First, turn on the power supply 1010 to supply power to the radar 103 on the first mounting part 102, and check whether the radar 103 is in normal working condition through the first controller 105.

[0065] Then, the second mounting part 141 is controlled by the second controller 106 to gradually approach the radar 103. During this process, the first controller 105 continuously monitors, records, and evaluates measurement data, such as recording the actual distance between the cone 142 and the radar 103, the actual time when the cone 142 receives the signal emitted by the radar 103, and the actual time when the radar 103 receives the signal reflected by the cone 142. It also calculates parameters such as the time difference and frequency of the signals from the cone 142 and the radar 103 at different actual distances. The second mounting part 141 moves until it contacts the limit switch 1081. At this time, the limit switch 1081 sends an electrical signal to the second controller 106, which then sends a stop signal to the servo motor 107. The servo motor 107 stops working, and the second mounting part 141 stops moving and stops at a point where... Figure 2 The location shown.

[0066] Next, the movement step size (e.g., 10mm or 20mm) and stop position are set in the second controller 106. The stop position can be set at a distance of 0.9m, 1m, etc. Then, the second controller 106 is activated, causing the second mounting part 141 to gradually move away from the radar 103. Each time the second mounting part 141 moves by one step, the second controller 106 controls the second mounting part 141 to stop. The first controller 105 then records the current actual distance (the distance between the second mounting part 141 and the first mounting part 102) and collects the signal data from the radar 103. The above process is repeated at each step position.

[0067] Finally, when the second mounting part 141 moves to the stop position (e.g.) Figure 1 Stop the test after reaching the indicated position.

[0068] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
