Intelligent handling trolley design based on STM32 and UWB communication
In complex handling scenarios,the operation of fixed-guided intelligent trolleys has limitations,while the free-path guided type can better meet the handling needs.In this paper,UWB spatial positioning technology is used to achieve high-precision target following,with STM32F103VET6 as the main control module.Information obtained through various sensor modules controls the left and right motors and drive the trolley to move the target position at different speeds.The spatial information acquired by the UWB tag module installed on the car and the target can accurately identify the spatial position of the trolley relative to the target by using the positioning algorithm,and the ultrasonic sensor,RFID tag sensor,magnetic stripe sensor and anti-collision stripe in the system can obtain a variety of information to ensure that the trolley can move to the target in free path guidance mode.After testing,the intelligent car can maintain good operation at low,medium and high speed no matter whether it is offree load or loaded in full manual mode,follow mode and tracking mode,and canadapt to a variety of complex scene operations,which is of great significance to industrial automation.
