[0031] In recent years, with the rapid development of intelligent connected vehicle technology and the continuous growth of the market's demand for professional talents, as the intelligent connected vehicle technology continues to progress and the sensor technology continues to develop, the performance of the environment perception system of intelligent connected vehicles is also constantly improving. Sensors in the environment perception system, such as millimeter-wave radars and ultrasonic radars, have become an important part of modern vehicles and are of great significance for improving driving safety and reducing traffic accidents. However, currently existing sensor teaching equipment on the market generally has the problems of insufficient integration and imperfect supporting software and course content, resulting in difficulties for teachers to display their teaching skills during actual teaching and being not conducive to students' efficient learning.

[0032] Therefore, referring to Figures 1 to 3 , the present utility model proposes a vehicle sensor training device, and the vehicle sensor training device includes:

[0033] A training table body 10;

[0034] A control terminal 20, and the control terminal 20 is arranged on the surface of the training table body 10;

[0035] A plurality of sensors 30, the plurality of sensors 30 are electrically connected to the control terminal 20 respectively, and the plurality of sensors 30 are configured to change detection parameters according to control signals output by the control terminal 20 and output a plurality of detection signals to the control terminal 20;

[0036] A connection end 80, the connection end 80 is connected to the control terminal 20, and the connection end 80 is configured to access the sensor 30;

[0037] The control terminal 20 is configured to obtain the working parameter signals sent by the sensor 30 through the connection end 80.

[0038] In this embodiment, the training bench body 10 can be implemented by means of a metal framework, a wooden panel, etc. The metal framework enables the training bench body 10 to have corresponding strength so as to bear the weight brought by the setting and installation of many components. Further, the metal framework further includes a storage box for placing devices such as a processor. Among them, the storage box is arranged under the wooden panel. Compared with metal, the wooden material of the wooden panel is non-conductive and has a lighter mass, which can effectively reduce the electromagnetic interference generated inside the electronic device and help maintain the stable operation of the device. In addition, the training bench body 10 is also provided with a pulley assembly to facilitate the movement of the training bench body 10. Among them, the size of the training bench body 10 is 1500*800*1200 (length * width * height). A plurality of openings are provided in the wooden panel to facilitate the setting of many components.

[0039] In this embodiment, the control terminal 20 can be implemented by a PC. The control terminal 20 includes a storage unit, and a computer program is stored in the storage unit. When the computer program is executed by a processor, it implements the corresponding teaching method. Among them, the computer program is a dedicated software for the vehicle sensor 30 training device. Specifically, the computer program includes four modules: cognition, installation and adjustment, fault detection, and application. Students can use this computer program to deeply study the intelligent networked vehicle technology with the sensors 30 and fault detection interfaces in the vehicle sensor training device.

[0040] In this embodiment, the multiple sensors 30 include, but are not limited to, image sensors 30, millimeter-wave radar sensors 30, ultrasonic radar sensors 30, and lidar sensors 30. Among them, the number of each type of sensor 30 is not limited either. The user can increase, decrease, or delete the number of each type of sensor 30 according to actual needs to meet the actual usage requirements of the user. On the vehicle sensor 30 training device, the image sensor 30 can be a high-resolution camera, which is used to capture detailed visual information around the simulated vehicle, such as pedestrians, other vehicles, traffic signs, and road conditions, and provide visual input data for the control terminal 20. The millimeter-wave radar sensor 30 can simulate detecting the position and relative speed of distant objects, enhance the target detection and tracking capabilities of the system in complex environments, and feedback the detection output to the control terminal 20. The ultrasonic radar sensor 30 is mainly used for detecting close-range obstacles, such as measuring the vehicle distance during parking assistance. The lidar sensor 30 constructs an accurate 3D point cloud map of the surrounding environment by emitting laser pulses and receiving the reflected signals, which is particularly crucial for achieving high-precision ranging and object recognition and is an indispensable component for realizing accurate navigation of autonomous driving. To further improve the practicality and teaching value of the vehicle sensor 30 training device, the user can flexibly adjust the sensor 30 configuration according to different teaching objectives or research directions. For example, when focusing on advanced driver assistance system (ADAS) training, it may be necessary to increase the number of image sensors 30 and lidar sensors 30 to deep learn and simulate complex road recognition and obstacle avoidance strategies. For learners dedicated to the development of vehicle automatic parking systems, they may focus more on increasing the number of ultrasonic radar sensors 30 and some image sensors 30 to optimize close-range obstacle detection and spatial perception capabilities.

[0041] In this embodiment, the number of the connection ends 80 is multiple, and the multiple connection ends 80 are used to be correspondingly connected to the multiple sensors 30 one by one. It can be understood that the connection ends 80 are open-hole interfaces arranged on the surface of the training table body 10. The user can obtain parameter signals of this interface through the detection terminals and feedback this parameter signal to the control terminal 20, so that the control terminal 20 can display this parameter signal on the touch display component 70 after processing. The trainee can obtain the parameter signals of the multiple sensors 30 through the multiple connection ends 80 and intuitively understand the signals such as the voltage and waveform of each sensor 30 through the touch display component 70.

[0042] The technical solution of the present utility model adopts a vehicle sensor training device. By arranging a plurality of sensors 30 on the training bench body 10, a plurality of detection signals are obtained. Among them, the types of the plurality of sensors 30 are different, and thus a variety of different detection signals are obtained. Such detection signals will be input to the control terminal 20, and the control terminal 20 will analyze and process such signals and display them on the touch display component 70, so as to facilitate the students to intuitively understand the working methods and principles of various sensors 30. In addition, the students can also debug various sensors 30 through the touch display component 70 to change the detection parameters of the sensors 30, so as to more deeply understand the working state of the sensors 30. In order to enable the students to more intuitively understand the working state of the sensors 30, the students can also obtain the parameter signals of the sensors 30 working through the connection end 80, effectively improving the teaching effect of the vehicle sensors 30 for the students and the quality of practical teaching.

[0043] Reference Figure 2 , in an embodiment of the present utility model, the vehicle sensor 30 training device further includes a power conversion module 40. The input end of the power conversion module 40 is electrically connected to the commercial power, and the output end of the power conversion module 40 is electrically connected to the plurality of sensors 30 and the control terminal 20. The power conversion module 40 is used to convert the input alternating current into direct current and output it;

[0044] Among them, the fault detection interface is arranged between the output end of the power conversion module 40 and the input ends of the plurality of sensors 30.

[0045] Furthermore, the power conversion module 40 includes:

[0046] A first voltage conversion circuit 41. The input end of the first voltage conversion circuit 41 is electrically connected to the commercial power, and the first voltage conversion circuit 41 is used to convert the input alternating current into a first direct current voltage and output it;

[0047] A second voltage conversion circuit 42. The input end of the second voltage conversion circuit 42 is electrically connected to the output end of the first voltage conversion circuit 41, and the output end of the second voltage conversion circuit 42 is electrically connected to the plurality of sensors 30 and the control terminal 20. The second voltage conversion circuit 42 is used to convert the input first direct current voltage into a second direct current voltage and output it.

[0048] In this embodiment, the first voltage conversion circuit 41 is an AC / DC voltage conversion circuit. Among them, the first voltage conversion circuit 41 can be implemented by means of linear power conversion, switched-mode power supply (SMPS), etc. Linear power conversion includes several steps such as AC input filtering, rectification (usually bridge rectification), filtering (smoothing the pulsating DC output), and linear voltage regulation. Linear voltage regulation adjusts the voltage by adjusting the conduction degree of transistors or zener diodes connected in series in the circuit. While the switched-mode power supply uses high-frequency switches (such as MOSFETs) to convert and regulate the power supply, isolates and transforms the voltage through a high-frequency transformer, and then obtains a stable DC output through rectification and filtering. Specifically, take the first voltage conversion circuit 41 as the way of linear power conversion. Among them, the input 220V alternating current is converted into 310V direct current, that is, the first DC voltage, by means of full-bridge rectification. Further, for multiple sensors 30 and the control terminal 20, the required supply voltages are often not the same, which results in that the 310V DC voltage output by the first voltage conversion circuit 41 still needs to be converted by voltage before it can directly supply power to the multiple sensors 30 and the control terminal 20. Therefore, the second voltage conversion circuit 42 is a DC / DC voltage conversion circuit. Among them, the second voltage conversion circuit 42 can adopt a buck converter: it is used when a higher input voltage needs to be converted into a lower output voltage. Its basic components include a switch (usually served by MOSFET), an inductor, a diode, and a capacitor. During operation, the switch conducts and turns off periodically. The inductor stores energy when the switch conducts, and releases energy to the load through the diode and capacitor when the switch turns off, so as to achieve voltage reduction. A boost converter: contrary to the buck converter, it is used to boost a low voltage to a high voltage. It also uses a switch, an inductor, a diode, and a capacitor, but the working mode is different. When the switch conducts, the inductor stores energy; when the switch turns off, the inductor discharges through the diode to the load and the capacitor, and the voltage boosts. A buck-boost converter: suitable for situations where the input voltage may be higher or lower than the required output voltage. It combines the characteristics of the buck and boost converters and can flexibly adjust the output voltage regardless of the relative level of the input voltage. Specifically, taking the buck converter as an example, the 310V first DC voltage output by the first voltage conversion circuit 41 can output a 12V second DC voltage through the buck converter to supply power to the sensor 30 and the control terminal 20.

[0049] Reference Figures 1 to 3, in an embodiment of the present utility model, the vehicle sensor 30 training device further includes a prompting module 50. The input end of the prompting module 50 is electrically connected to the output end of the power conversion module 40, and the controlled end of the prompting module 50 is electrically connected to the control terminal 20. The prompting module 50 is configured to output a prompting signal according to the prompting control signal output by the control terminal 20.

[0050] In this embodiment, the prompting circuit can adopt a voice prompting circuit such as a buzzer or a visual prompting circuit such as an LED. Specifically, taking the prompting circuit adopting a buzzer as an example. When a trainee uses the vehicle sensor 30 training device, the control terminal 20 is triggered to work by pressing a physical button. At this time, the buzzer can emit a sound to notify the user of the current state of the device. For example, the "beep" sound during the power-on self-check of the control terminal 20 indicates that the hardware is normal. In addition, when the trainee finishes debugging the image sensor 30, millimeter-wave radar sensor 30, ultrasonic radar sensor 30, lidar sensor 30, etc. through the control terminal 20, the buzzer will emit a sound as feedback to confirm that the operation has been received and executed by the system. The trainee can directly understand the working state of the vehicle sensor 30 training device through the prompting signal output by the prompting module 50 controlled by the prompting control signal output by the control terminal 20.

[0051] , in an embodiment of the present utility model, the vehicle sensor 30 training device further includes a switching circuit. The input end of the switching circuit is electrically connected to the output end of the power conversion module 40, the controlled end of the switching circuit is electrically connected to the control terminal 20, and the output end of the switching circuit is electrically connected to multiple sensors 30. The switching circuit is configured to conduct or cut off the path between the power conversion module 40 and multiple sensors 30 according to the switching control signal output by the control terminal 20.

[0052] In this embodiment, the switching circuit can be implemented by at least one switching tube, such as a MOS tube, IGBT tube, thyristor, triode, power tube, etc., and / or implemented by at least one switching device, such as a contactor and a relay. Specifically, the switching circuit between the control terminal 20 and the power conversion module 40 can be implemented by a relay, and the path between the control terminal 20 and the power conversion module 40 is conducted or disconnected through a push-button switch arranged on the surface of the training bench body 10. Multiple sensors 30 can be implemented by a switching circuit composed of switching tubes. Among them, the controlled end of the switching circuit is electrically connected to the control terminal 20, and the user outputs a switching control signal to the switching circuit through the control terminal 20 to realize the control of the control terminal 20 to start or close multiple sensors 30.

[0053] Reference Figures 1 to 3, in an embodiment of the present utility model, the vehicle sensor 30 training device further includes a positioning module 60. The output end of the positioning module 60 is electrically connected to the control terminal 20, and the positioning module 60 is used to output a positioning signal.

[0054] In this embodiment, the positioning module 60 includes a 4G antenna, a positioning antenna, and a directional antenna. Among them, the 4G antenna is mainly used for mobile data communication, that is, the data exchange between the device and the cellular network. Although the 4G antenna itself does not directly participate in the positioning process, when using a positioning module 60 that supports 4G communication (such as a GNSS + GSM / GPRS module), the 4G antenna can help the module transmit positioning data back to the server or terminal device through the cellular network. In this way, even without a direct data connection, remote monitoring and tracking can be achieved. The positioning antenna is specifically used to receive GNSS satellite signals, such as GPS signals. This type of antenna is designed to capture weak satellite signals propagating from different directions in the sky and convert them into electrical signals for the positioning module 60 to process. The positioning antenna needs to have good spatial coverage to ensure that enough satellite signals can be received for accurate three-dimensional positioning. It can be understood that the positioning antenna is usually installed on the top or side of the vehicle sensor 30 training device to avoid being blocked by metal or other obstacles. The directional antenna is used to concentrate energy in a specific direction and provides stronger signal reception or transmission ability in the pointed direction compared to an omnidirectional antenna. In a positioning application, if the general direction of the satellite signal source (usually the sky) is known, the directional antenna can be used to enhance the signal strength of a specific satellite to improve positioning accuracy and speed and achieve precise navigation teaching.

[0055] Reference Figures 1 to 3 , in an embodiment of the present utility model, the vehicle sensor 30 training device further includes a touch display component 70. The power supply end of the touch display component 70 is electrically connected to the output end of the power conversion module 40. The touch display component 70 is electrically connected to the control terminal 20. The touch display component 70 is used to output a display signal according to the display control signal output by the control terminal 20 and is used to input a touch signal to the control terminal 20.

[0056] In this embodiment, the touch display component 70 is mainly a device that integrates the touch function and the display function to achieve an intuitive interaction between the user and the electronic device. Specifically, the touch display component 70 can be implemented by capacitive touch display, resistive touch display, etc. Among them, capacitive touch relies on the capacitance effect of the human body and works by embedding one or more layers of transparent conductive material grids under the glass layer. When a finger touches the screen, it will cause a change in capacitance, which is then detected by the touch sensor 30 to determine the touch position. The trainee can select the content displayed on the screen of the control terminal 20 by touching the screen, and can also realize the teaching work through the information displayed by the control terminal 20 on the screen. For example, when the trainee selects "Cognition" through the touch display component 70 and selects the option of "Ultrasonic Radar" in the "Cognition" option, the working principle, internal structure and application of the ultrasonic radar will be displayed on the screen. The trainee can independently select the learning content through the touch display component 70, effectively improving the convenience of the trainee's learning.
