Technical Field

[0001] This application relates to the field of testing, and in particular to a test bench. Background Technology

[0002] With the rapid development of autonomous driving technology, software plays an increasingly prominent role in autonomous driving systems. To improve material handling efficiency and automation within the factory, an autonomous transport vehicle was designed. During the design process, to ensure the reliability and safety of the autonomous driving software, engineers continuously adjusted the positions of radar 2 and radar 1 on the autonomous transport vehicle. They also recorded in real-time the data flow received from radar 2 on the switch and the feedback from the domain control device on the data from radar 1. Based on the data results, the optimal positions were then selected for installing the aforementioned components.

[0003] Because the positions of the above structures need to be constantly adjusted, multiple disassemblies or installations are required on the automated guided vehicle. Engineers need to avoid the vehicle frame, and sometimes it is necessary to drill holes along with the frame. The operation is relatively complicated and the testing efficiency is low.

[0026] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.

[0027] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

[0028] Example 1:

[0029] This application discloses a test bench. (Refer to...) Figure 1 , Figure 2 and Figure 3 The system includes a mounting frame 1, several mounting platforms 2 mounted on the mounting frame 1, and test components mounted on the mounting platforms 2. The test components include a radar 6 mounted on the mounting platform 2 and located at the top of the mounting frame 1, a switch 3 mounted on the mounting platform 2 and located at the top of the mounting frame 1, a radar 4 mounted on the mounting platform 2, and a domain control device 5. During implementation, additional sensors and other detection components can be added, depending on the testing functions required for the autonomous vehicle. Several adjustment holes 7 are provided on the mounting platform 2, and several mounting seats 8 are mounted on the mounting platform 2. Connecting blocks 9 are fixedly installed on the bottom of the mounting seats 8 corresponding to the adjustment holes 7. The mounting platform 2, located at the top of the mounting frame 1, is situated on the top surface of the mounting frame 1. The horizontal height of the top edge of the mounting frame 1 is lower than the horizontal height of the mounting platform 2, ensuring that the top mounting platform 2 is unobstructed, reducing the impact factors during radar 6 testing. Simultaneously, radar 6 and radar 4 can be compared, facilitating testing personnel to measure radar data results with and without obstruction, as well as the combined testing effect, thereby improving the testing effect and quality for autonomous vehicles.

[0030] Reference Figure 1 and Figure 2In this embodiment, the mounting platform 2 is configured with two sets, forming two layers on the mounting frame 1. Radar 1 6 and switch 3 are installed on the top layer. Two sets of radar 1 6 are configured, and one set of switch 3 is configured, with switch 3 positioned between the two sets of radar 1 6. Radar 1 6, mounted on the top platform, can detect areas covering the perimeter of the mounting frame 1, simulating the perception of the surrounding environment by an autonomous vehicle during operation. Radar 1 6 is connected to switch 3 via a high-speed data cable. Environmental data collected by radar 1 6, such as obstacle shape, location, and trajectory, is transmitted to switch 3 at high speed. Radar 2 4 and domain control device 5 are installed on the next layer. Two sets of radar 2 4 are configured, and one set of domain control device 5 is positioned between the two sets of radar 2 4. Radar 2 4, through its three-dimensional spatial detection capability, performs a three-dimensional scan of the environment surrounding the platform, providing richer and more accurate obstacle distribution and environmental feature data for simulating autonomous vehicles. Radar 2 4 is directly connected to the domain control device 5 on the second layer via a high-speed communication cable, transmitting the scanned environmental data to the domain control device 5 in real time. This data complements the data from radar 1 6, jointly constructing a highly realistic test scenario.

[0031] Reference Figure 1 and Figure 2 Domain controller 5, acting as the "intelligent brain" of the entire test and simulation platform, receives data from radar 6 (forwarded from layer 1 switch 3) and data from radar 4 (from layer 2 switch 4). Domain controller 5 incorporates complex and efficient decision-making algorithms and planning models to receive, process, and analyze this massive amount of environmental data in real time. Based on precise path planning algorithms and intelligent decision-making mechanisms, it rapidly generates scientifically sound vehicle control commands. These commands are accurately transmitted to virtual or real vehicle actuators (which can be simulated as corresponding execution modules in the test and simulation platform) via reliable communication interfaces (such as CAN bus or Ethernet interface), enabling simulated control of the autonomous driving process. Simultaneously, feedback information from the vehicle actuators can also be transmitted back to domain controller 5 via the communication link, forming a closed-loop control and test verification system.

[0032] Reference Figure 1 and Figure 2The mounting platform 2 has several through slots 25 for wire harnesses to pass through. In this embodiment, the test components of each layer adopt a redundant combination of CAN bus, Ethernet, and fiber optic communication links. The through slots 25 facilitate the connection and testing of multiple lines, ensuring high reliability and anti-interference of critical data transmission. During normal operation, multiple communication links transmit data simultaneously, serving as backups for each other; when one link fails, the system can automatically switch to other normal links, ensuring uninterrupted testing and continuous and accurate data transmission. An intelligent data synchronization protocol and real-time monitoring mechanism are constructed to effectively solve the time synchronization and data consistency problems in the multi-sensor data fusion process. Through precise timestamp marking and data verification algorithms, it is ensured that the data from each sensor are synchronized in time and accurate in content, providing a reliable data foundation for the precise decision-making of the domain control device 5. Simultaneously, the real-time monitoring mechanism monitors the status of communication links and the operating status of the equipment in real time. Once an anomaly is detected, an alarm is immediately issued and corresponding fault handling measures are taken to ensure the overall stability of the platform operation.

[0033] Reference Figure 2 and Figure 3 The top surface of the mounting base 8 has a through hole 10 corresponding to the mounting thread hole position of the test component. A fixing component is installed on the mounting base 8, which fixes the test component on the mounting base 8, improving the stability of the test component on the mounting base 8. The test position of the test component can be adjusted by adjusting the position of the plug block 9 on the adjustment hole 7.

[0034] Reference Figure 1 and Figure 2 The bottom of the mounting frame 1 is fixedly equipped with several casters 16, which facilitate the movement of the mounting frame 1 and the displacement of the entire test bench. Test personnel can perform debugging and verification in the test environment, easily obtain real-time operating status and test result feedback of the test components, and quickly locate and solve test problems based on the test results, improving test efficiency. The side of the mounting platform 2 is provided with a mounting frame 17 connected to the mounting frame 1. A support base 18 is installed at the end of the mounting frame 17 that contacts the mounting frame 1. The support base 18 supports the mounting platform 2, improving the stability of the mounting platform 2 on the mounting frame 1. The support base 18 has a positioning groove 19 on the side facing the mounting frame 17, and the mounting frame 17 has an adjustment groove 20 along its length. A fastener is installed on the support base 18, fixing the support base 18 to the mounting frame 17. In this embodiment, the fastener is an expansion bolt; however, in specific implementations, holes can also be drilled in the mounting frame 17, and ordinary bolts can be used for fixing.

[0035] Reference Figure 1 and Figure 2To improve the stability between the mounting frame 17 and the mounting bracket 1, a second support base 21 connected to the mounting frame 17 is installed on the mounting bracket 1. The second support base 21 is located at one end of the mounting frame 17. A second positioning groove 22 and a third positioning groove 23 are provided on the side of the second support base 21 facing the mounting bracket 1 and the mounting frame 17, respectively. An adjustment groove 24 is provided along the length of the mounting bracket 1, and an adjustment groove 20 is provided along the length of the mounting frame 17. In this embodiment, all four side walls of the mounting frame 17 along its length are provided with adjustment grooves 20 to facilitate the connection between the second support base 21 and the mounting frame 17. A second fastener is installed on the second support base 21. In this embodiment, two sets of the second fastener are provided for each second support base 21, fixing the second support base 21 to the mounting bracket 1 and the mounting frame 17. In this embodiment, the second fastener is an expansion bolt. In practice, holes can be drilled in the mounting frame 17 for fixing with ordinary bolts or embedded blocks.

[0036] The implementation principle of a test bench according to an embodiment of this application is as follows: The mounting base 8 mounts the test component onto the test platform. The tester positions the component on the platform by inserting the connector 9 into the mounting base 8. After testing a certain area is completed, the tester can disassemble the mounting base 8 and reinstall it on the test platform. This facilitates rapid acquisition of test data, allows for position adjustments based on real-time data, and improves testing efficiency.

[0037] Example 2:

[0038] The difference between this embodiment and Embodiment 1 is that, referring to... Figure 4 The mounting base 8 includes a base 11 and an adjusting plate 12 mounted on the base 11. The base 11 has a groove 13 along its length. A slider 14 located within the groove 13 is fixed on the adjusting plate 12. A plug-in block 9 is located on the bottom surface of the base 11. The adjusting plate 12 is slidably connected to the base 11 via the slider 14 and the groove 13. The test component is mounted on the adjusting plate 12. A positioning hole 15 is provided on the top surface of the adjusting plate 12 corresponding to the mounting threaded hole of the test component. A fixing component two is mounted on the mounting base 8 to fix the test component to the adjusting plate 12. The adjusting plate 12 facilitates fine adjustments to the position of the test component and also makes it easier for the tester to drill holes. The tester does not need to frequently drill holes in the mounting platform 2, which affects the overall strength and stability of the mounting platform 2, simplifying the installation process and reducing installation difficulty. In this embodiment, the fixing component two is a bolt.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
