For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In order to solve the problem of low efficiency of accuracy calibration of existing radar probes, the utility model provides a multi-station high-precision automatic radar detection device, including: a test bench; a plurality of clamping devices, arranged on the test bench, respectively used to clamp different radar probes; a baffle, arranged at the front end of the test bench, perpendicular to the detection direction of the radar probe; a sliding track, parallel to the detection direction of the radar probe, and slidingly matched with the baffle.

[0031] The multi-station high-precision automatic radar detection device of some embodiments of the present disclosure is described below through specific examples.

[0032] like Figure 1 and Figure 2 As shown, the precision detection platform of the radar probe 1 provided by the utility model comprises a test platform 2, a clamping device 3 and a baffle 4. The test platform 2 is placed on a horizontal ground, and the clamping device 3 is installed on the test platform 2. The radar probe 1 is clamped and fixed by the clamping device 3 and kept in a horizontal state, so that the radar probe 1 can measure distance in the horizontal direction. The baffle 4 is vertically arranged at the front end of the test platform 2 and is perpendicular to the detection direction of the radar probe 1.

[0033] After the radar probe 1 is fixed by the clamping device 3, the baffle 4 is first moved to fit the radar probe 1, which is used as the initial end. Then the baffle 4 is moved a known distance S along the detection direction of the radar probe 1, and the distance S' measured by the radar probe 1 is read. S and S' are compared to determine whether the accuracy of the radar probe 1 is within the error range.

[0034] In some examples, the clamping device 3 includes a mounting plate 31, a clamping driver 32, a first clamping plate 33, and a second clamping plate 34. The clamping driver 32 is fixed to the mounting plate 31. The first clamping plate 33 and the second clamping plate 34 are opposite to each other and at least one of them is connected to the mounting plate 31 in a sliding direction in the horizontal direction. The clamping driver 32 is configured to drive at least one of the first clamping plate 33 and the second clamping plate 34 to move so that the first clamping plate 33 and the second clamping plate 34 are moved closer to each other to clamp the radar probe 1 or away from each other to release the radar probe 1. Specifically, the clamping driver 32 is a cylinder, and the piston rod of the clamping driver 32 is connected to the first clamping plate 33 to push the first clamping plate 33 to move back and forth.

[0035] For example, the first clamp plate 33 and the second clamp plate 34 are both V-shaped clamp plates, the V-shaped groove of the first clamp plate 33 is recessed toward the side away from the second clamp plate 34, and the V-shaped groove of the second clamp plate 34 is recessed toward the side away from the first clamp plate 33, so as to facilitate clamping the cylindrical area in the radar probe 1.

[0036] Of course, it should be specially noted that the above structure of the clamping device 3 is only described as a specific example of the present invention, and does not mean that the clamping device 3 can only adopt the above structure. Without departing from the principle of the present invention, technical personnel in this field can also adopt other devices for clamping, which should be included in the protection scope of the present invention.

[0037] In addition, a plurality of clamping devices 3 may be provided on the test bench 2, and each clamping device 3 may clamp a radar probe 1. The clamped radar probes 1 may be simultaneously tested for accuracy, thereby improving the detection efficiency.

[0038] Since the sizes of radar probes 1 of different specifications are different, the heights are also different. In order to facilitate adaptation to radar probes 1 of different specifications, the utility model sets a support device 5 on the test bench 2. The radar probe 1 is placed on the support device 5, and the support device 5 is configured to adjust the height so that the radar probe 1 remains horizontal, so as to ensure the accuracy of the ranging of the radar probe 1. Specifically, the support device 5 includes a support plate 51, an adjustment mechanism and a guide rod 52, the guide rod 52 is vertically fixed on the test bench 2, the support plate 51 is horizontally arranged and slidably cooperates with the guide rod 52, and the adjustment mechanism is used to adjust the height of the support plate 51 on the guide rod 52. For example, the adjustment mechanism is an adjustment cylinder arranged at the bottom of the support plate 51 or an adjustment screw threadedly connected to the support plate 51.

[0039] In order to facilitate the movement of the baffle 4, a sliding track 6 can be provided, and the sliding track 6 is parallel to the detection direction of the radar probe 1. The baffle 4 and the sliding track 6 are slidably matched, and the baffle 4 can remain perpendicular to the detection direction of the radar probe 1 after sliding along the sliding track 6, so as to avoid measurement errors caused by the deflection of the baffle 4. For example, the sliding track 6 is provided on the top of the factory building, and the baffle 4 is suspended below the sliding track 6; or, the sliding track 6 is provided on the ground, and the baffle 4 is installed on the sliding track 6.

[0040] In some examples, the precision detection platform of the radar probe 1 further includes a moving device, which is configured to drive the baffle 4 to reciprocate along the sliding track 6, thereby improving the automation of the precision detection platform and thus improving the efficiency of precision inspection. Specifically, the moving device includes a stepper motor and a power transmission component, and the stepper motor drives the baffle 4 to reciprocate along the sliding track 6 through the power transmission component. For example, the power transmission component is a sprocket chain assembly or a screw assembly.

[0041] In order to facilitate the acquisition of the known distance S that the baffle 4 moves along the detection direction of the radar probe 1, the utility model sets a control device on the test bench, and the control device is used to measure the actual distance between the test bench 2 and the baffle 4, so as to improve the efficiency of measuring the known actual distance S, thereby improving the efficiency of the radar probe 1 for accuracy verification.

[0042] In some examples, the control device is a rangefinder, and the detection direction of the rangefinder is perpendicular to the baffle 4. When the baffle 4 contacts the radar probe 1, the reading a of the rangefinder is recorded. When the baffle 4 moves to the distance to be measured, the reading b of the rangefinder is recorded, and the actual distance S between the baffle 4 and the radar probe 1 is ba.

[0043] In other examples, the control device is a stepping distance measuring module, which is configured to measure the number of rotations of the stepping motor to calculate the moving distance of the baffle 4. For example, when the baffle 4 moves to contact the radar probe 1, the count of the stepping distance measuring module is reset, and then the baffle 4 is moved to the distance to be measured, and the known distance S moved by the baffle 4 can be directly read out through the stepping distance measuring module.

[0044] In summary, the principles of the present invention are as follows:

[0045] First, start the moving device to drive the baffle 4 to slide along the sliding track 6 until it contacts the radar probe 1, and record the rangefinder reading a; then start the moving device to drive the baffle 4 to slide along the sliding track 6 and away from the radar probe 1. After moving to the approximate range, record the rangefinder reading b and the reading S′ of the radar probe 1, and compare the values ​​of S′ and ba to determine whether the accuracy of the radar probe 1 meets the requirements.

[0046] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
