Description

Technical Field

[0001] This utility model belongs to the field of sensor dynamic fusion testing technology, and in particular relates to a device installation structure for a sensor dynamic fusion testing platform. Background Technology

[0002] Sensor dynamic fusion testing is an indispensable part of the development and verification of modern complex systems, especially in fields such as autonomous driving, industrial automation, robotics, and aerospace. Sensor dynamic fusion testing is crucial for improving the reliability, accuracy, real-time performance, environmental adaptability of systems, and verifying the effectiveness of fusion algorithms.

[0003] When evaluating the performance of sensors in dynamic environments, exciters are an essential component. Current dynamic fusion test platforms for sensors mainly consist of a computer, signal output card, signal output junction box, signal acquisition card, signal acquisition junction box, power amplifier, exciter, and equipment mounting platform that are fixedly connected to each other.

[0004] To improve the overall system performance, the test platform employs multiple high-precision one-dimensional and three-dimensional sensors. These sensors differ significantly in data type, accuracy, data volume, and application scenarios. After acquiring data from the high-precision one-dimensional and three-dimensional sensors, the computer performs data fusion optimization, fully leveraging the advantages of both sensors to enhance the overall system performance.

[0005] Existing sensor dynamic fusion testing platforms employ rudimentary equipment installation methods. When multiple sensor data fusion is required, sensors and exciters must be repeatedly disassembled and reassembled to acquire multiple sets of data before fusion optimization, making the testing process time-consuming and labor-intensive. Therefore, an integrated equipment installation structure is needed that eliminates the tedious steps of repeated disassembly and reassembly. Utility Model Content

[0006] Purpose of the utility model: The technical problem to be solved by this utility model is how to improve the detection efficiency and accuracy of the detection results of the sensor dynamic fusion test platform.

[0007] Technical Solution: The device installation structure of the sensor dynamic fusion test platform of this utility model includes a base plate and a turntable rotatably connected thereto; multiple positioning rods for mounting sensors are fixedly connected on the turntable; the base plate is also provided with a mounting bracket for mounting a vibrator, the vibrator forming a detection area that cooperates with the sensor detection, and the mounting bracket is provided with telescopic rods in the X, Y and Z axis directions respectively; when the positioning rod rotates to the detection area, the telescopic rod extends to the vibrator at its end and fits against the sensor surface.

[0008] Furthermore, the mounting frame includes a first bracket, a second bracket, and a top plate facing the X, Y, and Z axes respectively. The first and second brackets are provided with a plurality of support rods, and the top plate is fixedly connected to the support rods. The telescopic rod is fixedly installed on the first bracket, the second bracket, and the top plate respectively.

[0009] Furthermore, the positioning rod consists of two rods. One positioning rod is equipped with a mounting base, on which a three-dimensional sensor is fixedly mounted. The other positioning rod is equipped with a force-bearing base, on which high-precision one-dimensional sensors are mounted on its sides facing the X, Y, and Z axes.

[0010] Furthermore, the turntable includes a base fixedly connected to the base plate, a stepper motor located inside the base, and a transmission cover located above the base. The transmission cover has an internal gear ring on its side wall, and a gear that meshes with the internal gear ring is installed on the output end of the stepper motor.

[0011] Furthermore, both the first and second supports are U-shaped supports with downward openings.

[0012] Furthermore, both the first and second brackets are equipped with reinforcing plates inside.

[0013] Furthermore, the telescopic rod includes a telescopic rod with a pneumatic telescopic cylinder.

[0014] Furthermore, both the first and second supports are equipped with supports on top, and the telescopic rod is installed inside the supports.

[0015] Beneficial effects: Compared with the prior art, the advantages of this utility model are as follows: The sensor of this utility model is installed on the positioning rod. When the positioning rod rotates to the detection area, the telescopic rod extends to the vibrator at its end, which is in contact with the sensor surface. When the positioning rod enters the detection area, the extension of the telescopic rod causes the vibrator to contact the sensor for detection. When replacing the sensor for detection, it is only necessary to retract the telescopic rod and rotate the turntable to the next positioning rod entering the mounting area. The entire equipment installation structure can complete the detection and data fitting without repeatedly disassembling the vibrator and sensor, thus improving detection efficiency and data accuracy.

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1-4 A sensor dynamic fusion testing platform equipment installation structure includes a base plate 1, a turntable 2 mounted on the upper end of the base plate 1, positioning rods 3 mounted on both sides above the turntable 2, a mounting base 4 mounted on the upper end of one positioning rod 3, a three-dimensional sensor 5 mounted on the upper end of the mounting base 4, and the four corners of the three-dimensional sensor 5 connected to the mounting base 4 by screws; a force-bearing seat 6 mounted on the upper end of the other positioning rod 3, a high-precision one-dimensional sensor 7 mounted on one side, the rear end and the upper end of the force-bearing seat 6, a first bracket 8 set on one side of the turntable 2, a second bracket 9 set on the rear end of the turntable 2, and supports 11 mounted on top of both the first bracket 8 and the second bracket 9. A support rod 12 is provided on the outside of the support rod 12, and a top plate 13 is installed on the upper end of the support rod 12. Telescopic rods are installed inside the support 11 and the top plate 13. In this embodiment, the telescopic rod is the telescopic rod 14 of the pneumatic telescopic cylinder. A vibrator 15 is installed on the telescopic rod 14 of the pneumatic telescopic cylinder. The vibrator 15 and the telescopic rod 14 located in the X, Y and Z axis directions form a detection area. The output ends of the high-precision one-dimensional sensor 7 and the three-dimensional sensor 5 are electrically connected to the input end of the control terminal. The output end of the control terminal is connected to the pneumatic telescopic cylinder through the cylinder drive module. A connecting seat 301 is installed at the lower end of the positioning rod 3, and the connecting seat 301 is connected to the turntable 2 by screws.

[0022] In use, the three-dimensional sensor 5 and the high-precision one-dimensional sensor 7 are pre-installed on the mounting base 4 and the force-bearing base 6. Three high-precision one-dimensional sensors 7 are provided, fixed to the X, Y, and Z axes of the force-bearing base 6 respectively. During testing, the turntable is first rotated until the positioning rod 3, on which the force-bearing base 6 is mounted, rotates to the detection area. The control terminal controls the operation of three sets of pneumatic telescopic cylinders 14 via the cylinder drive module. The three sets of pneumatic telescopic cylinders 14 are located in the X, Y, and Z axes of the force-bearing base 6 respectively. After extension, the exciter 15 at the end of the pneumatic telescopic cylinder 14 can abut against the surface of the three-axis high-precision one-dimensional sensor 7 of the force-bearing base 6. Based on the force applied by the exciter 15 to the three-axis high-precision one-dimensional sensor 7 of the force-bearing base 6, three-dimensional... The force signal detected by the high-precision one-dimensional sensor is fed back to the terminal as training parameters for the fusion optimization module. After completion, the turntable 2 drives the force seat 6 and the position of the three-dimensional sensor 5 to switch. At this time, the control terminal repeats the previous operation. When the three-dimensional sensor 5 is installed and enters the detection area, it drives the three sets of pneumatic telescopic cylinders 14 to extend along the three-axis direction and apply force to the three-axis direction of the three-dimensional sensor 5. The force signal of the three-axis of the three-dimensional sensor 5 can be obtained. After the signal is fed back to the terminal, the computer can construct the static link in the dynamic fusion optimization module based on the previously collected high-precision data, using neural networks or support vector machines, and construct the dynamic link in the dynamic fusion optimization module using differentiators or delayers.

[0023] When optimizing two-dimensional or one-dimensional sensors, only a high-precision one-dimensional sensor 7 is installed on the corresponding dimension surface of the force-bearing seat 6, and the force is applied by the pneumatic telescopic cylinder 14 that controls the corresponding axis direction during subsequent force detection.

[0024] Please see Figure 4 The turntable 2 includes a base 201 fixedly mounted on the base plate 1, a transmission cover 202 rotatably connected above the base 201, an internal gear ring 203 provided on the lower end face of the transmission cover 202, a stepper motor 204 installed inside the base 201, a gear 205 installed on the output end of the stepper motor 204, and the output end of the stepper motor 204 is connected to the internal gear ring 203 through the gear 205.

[0025] The stepper motor 204 drives the internal gear ring 203 on the bottom surface of the transmission cover 202 through the gear 205, which can drive the transmission cover 202 to rotate, thereby changing the position of the force support 6 and the three-dimensional sensor 5. This allows for efficient detection without disassembling the high-precision one-dimensional sensor 7 on the force support 6.

[0026] Please see Figure 1 The first support 8 and the second support 9 are U-shaped supports with downward openings, and each of them is equipped with a reinforcing plate 10, which improves the structural strength of the first support 8 and the second support 9.
