Description

Technical Field

[0001] This utility model relates to the field of teaching experimental equipment technology, and in particular to a multimodal teaching intelligent vehicle. Background Technology

[0002] Analog and digital circuit experiments are common in teaching. Analog circuit experiments have various methods, with traditional methods primarily involving building circuits on experimental boxes to verify the functions of transistor circuits, operational amplifier circuits, and power amplifier circuits. Digital circuit experiments also have various methods, with traditional methods primarily involving building circuits on experimental boxes or pocket boards to verify the functions of gate circuits, combinational logic circuits, and sequential logic circuits. These traditional methods fail to connect the experimental content to real-world applications, hindering students' understanding of the application value of digital and analog circuit engineering and failing to enhance their learning interest. Furthermore, these experiments require individual sessions and are limited to a single mode, which cannot meet the requirements of high-quality teaching. Utility Model Content

[0014] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] Please see Figure 1 This application provides a multimodal teaching intelligent vehicle, including a vehicle body 1, four rectangularly distributed Mecanum wheels 2 mounted on the vehicle body 1, a rotary drive device and a battery 3 installed inside the vehicle body 1, a laser rangefinder sensor 4 mounted on the outer wall of the vehicle body 1, and an embedded system module 5, a digital electronics experiment module 6, an analog electronics experiment module 7, and a bracket 8 mounted on the top of the vehicle body 1. The embedded system control board is an STM32F407. The embedded system module 5 is electrically connected to the digital electronics experiment module 6, the analog electronics experiment module 7, the laser rangefinder sensor 4, the battery 3, and the robotic arm 9. The rotary drive device is electrically connected to the analog electronics experiment module 7. The robotic arm 9 is mounted on the bracket 8. Appropriate grippers can be mounted on the robotic arm 9 for easy control and gripping. The battery 3 supplies power to each electrical component.

[0016] Two rotary drive units are configured, with two Mecanum wheels 2 serving as front wheels and connected to the two rotary drive units respectively. Each rotary drive unit includes a motor 14 and a reducer 15. The output of the motor 14 is connected to the reducer 15, and the output of the reducer 15 is connected to the Mecanum wheels 2.

[0017] The analog electronics experimental module 7 includes an analog electronics experimental motherboard 10. The lower half of the analog electronics experimental motherboard 10 has a motor 14 drive circuit 11 and a breadboard 12, while the upper half of the analog electronics experimental motherboard 10 has four connection areas 13. The connection areas 13 are used to set up analog electronics motor drive modules or motor drive development modules.

[0018] In the analog electronics experiment motherboard 10, each unit of the motor 14 drive circuit 11 is connected in series to form an electronic system that can automatically adjust the speed. Students only need to adjust the parameters appropriately to make it work.

[0019] The analog motor drive module consists of four unit modules, corresponding to the four circuits driving motor 14: drive signal generation circuit, initial velocity and speed balance adjustment circuit, obstacle detection speed regulation signal generation circuit, speed regulation circuit, and motor 14 drive circuit 11. Based on these four unit modules, students can complete principle experiments such as integrated operational amplifier signal generation, proportional amplifier experiment, comparator experiment, transistor amplifier experiment, emitter follower experiment, and DC power amplifier experiment, as well as engineering problem-solving experiments such as operational amplifier zero adjustment, circuit consistency, and motor 14 consistency.

[0020] The motor drive development module also consists of four unit modules, corresponding to the four circuits driving the motor 14: the drive signal generation circuit, the initial speed and speed balance adjustment circuit, the obstacle detection speed regulation signal generation circuit, the speed regulation circuit, and the motor 14 drive circuit 11. Unlike the analog motor drive module, these four circuits need to be designed by students themselves. The method is to use the components provided by the module to connect and build the circuit, and test and verify the circuit performance. Based on the four unit modules, students can complete circuit design experiments such as integrated operational amplifier signal generation, proportional amplifier, comparator, transistor amplifier, emitter follower, and DC power amplifier, as well as engineering problem solving experiments such as consistency debugging with the mainboard motor 14 drive circuit 11.

[0021] Laser rangefinders 4 are installed on the four side walls of the vehicle body 1 (front, rear, left, and right). The laser rangefinders 4 are used to detect obstacles and facilitate obstacle avoidance.

[0022] The front of the vehicle body 1 can be equipped with a front bracket 8 for mounting a tracking sensor to conduct a four-channel infrared tracking sensor application experiment; or it can be equipped with an eight-channel grayscale sensor to conduct an eight-channel grayscale sensor application experiment.

[0023] The embedded system module 5 is equipped with a wireless WIFI module. The WIFI module is used for wireless control of the motor 14 and power supply to various electrical components.

[0024] The design experiments in Digital Electronics Experiment Module 6 support experiments on combinational logic circuits, sequential logic circuits, etc. Each experiment is divided into two categories: principle verification and application design. Considering the students' basic knowledge and abilities, the principle verification experiment adopts the method of dragging and dropping chips online and building experimental circuits with electronic wiring.
