One side of the inner bottom wall of the base 1 is fixedly connected with a ultrasonic sensor 3. The upper surface of the base 1 is fixedly connected with a tool rack 4. On both sides of the upper surface of the tool rack 4, UWB modules 5 are fixedly connected by bolts. One side of the outer surface of the tool rack 4 is fixedly connected with a first infrared sensor 6. One side of the outer surface of the tool rack 4 close to the first infrared sensor 6 is fixedly connected with a first camera 7. The other side of the outer surface of the tool rack 4 is fixedly connected with a second infrared sensor 8. One side of the outer surface of the tool rack 4 close to the second infrared sensor 8 is fixedly connected with a second camera 9.

[0024] During specific use, through the settings of the AGV drive wheel 2, ultrasonic sensor 3, UWB module 5, first infrared sensor 6 and first camera 7, a tool vehicle capable of automatically following the operator's walking is adopted. The straight section of the operation is planned in advance, and the tool vehicle walks on this straight section. The UWB module 5 is used to judge the positions of the operator and the following tool vehicle. The first infrared sensor 6 and the second infrared sensor 8 are installed around the following vehicle to assist in judging the accurate relative positions of the person and the vehicle (such as left or right), and the positions of the person are further confirmed through the first camera 7 and the second camera 9 to ensure the accuracy during use. The AGV drive wheel 2 enables the device to move smoothly, improves the moving efficiency, and a ultrasonic sensor 3 is installed on the following vehicle for obstacle avoidance when there are obstacles, improving the obstacle avoidance effect of the device and preventing the device from hitting obstacles and being damaged. On this basis, multiple UWB modules 5 can also be arranged indoors, and the server is used to calculate the positions of the trolley and the person, and uniformly allocate the walking of the tool vehicle. In this way, the operator can bind and unbind the paired tool vehicle at any time, and can also flexibly define the walking straight section (which can be an imaginary or virtual straight section). All information can be presented on the dashboard, replacing the hand-pulled tool vehicle that requires manual movement. During the entire operation process, it follows the operator along a fixed straight track on the production line. When it is necessary to put back tools or pick up parts, only a small turn or movement is required to complete the action, and there is no need for manual movement of the tool vehicle during the operation process, thereby reducing the labor intensity of workers, improving production efficiency, and shortening the cycle of the production line.
