摘　　要：针对疫情期间外卖配送可能导致接触感染,设计了一种小型无人送餐车的控制系统,通过STM32微控制处理器实现全自动无人配送目标。该系统不仅可以实时监测餐饮温湿度并上传到上位机,还能通过安装在小车头部的红外循迹模块和北斗定位模块引导其按指定路径行驶。利用超声波传感器监测与障碍物距离,进而调整车速和方向及时应对路况变化。在实验车上取得了较好的应用效果,实现一定范围内外卖配送自动化。In view of the possibility of contact infection caused by takeout during the epidemic,a control system of small unmanned food delivery truck was designed to achieve the full automatic unmanned delivery by STM32 microprocessor.The system can not only monitors the food and beverage temperature and humidity in real time and uploads it to the host computer,but also guides the cart along a specified path by means of an infrared tracking module and a BeiDou positioning module mounted on the cart's head.Ultrasonic sensors are used to monitor the distance to obstacles to adjust the speed and direction of the cart,so that it can respond to changes in road conditions in time.A good application effect is achieved on test cart.A certain range of delivery automation is achieved.
