Abstract
With the rapid development of the catering industry, the demand for food delivery service is increasing. In order to improve the efficiency and user experience of food delivery, it is particularly important to design an intelligent food delivery car. This design uses STM32 microcontroller as the core control unit, integrates a variety of sensors and control modules, and realizes a number of intelligent functions. In terms of hardware, the car realizes autonomous navigation through infrared tracking tube, ultrasonic sensor is used to detect obstacles in front to avoid collision, and infrared speedometer is used to measure the speed of the car. The camera module is used to remotely monitor the operation of the car to ensure the transparency and safety of the meal delivery process. In terms of software, the system uses keil5 programming to realize the real-time acquisition and processing of sensor data, and communicate with the mobile terminal through Bluetooth module. Users can control the motion state of the car through the mobile terminal, and receive the speed, distance and other information of the car. The mobile terminal also has voice broadcast function, which can remind users to pick up meals in time. In terms of technology, this design comprehensively uses embedded programming, sensor data processing, wireless communication and image processing technology to realize the intellectualization and autonomy of the dining car. The experimental results show that the intelligent food delivery car can significantly improve the efficiency of food delivery, reduce human errors, and provide users with more convenient and efficient food delivery services.
