电机驱动原理

AbstractWith the development of science and technology and the improvement of social economy,more and more industrial business needs continue to emerge.At the same time,with theimprovement of the production level of all walks of life,countries around the world areactively investing in the research of intelligent distribution vehicles,through the application ofadvanced electronic technology,information technology,electronic communicationtechnology,etc.to promote the progress of intelligent distribution vehicle technology,as faras possible to achieve the goal of gradually realizing mechanization,intelligence,and highautomationThe intelligent material trolley adopts a chip based on the STM32 series as the main control.This series of chips combines multiple registers,with rich interrupt logic,clock configurationenable control and other concepts,as well as a variety of hardware external interfaces,such asreset circuit,RS232,RTC circuit,SD card interface,etc.,while the firmware library ofSTM32 series chips has many practical structures and pointer variables,the series of chipshave a streamlined structure,which can realize the control of motors,sensors and otherperipherals.The hardware of the trolley is composed of a minimum system,a power supplycircuit,a motor drive circuit,a tracking circuit,an obstacle avoidance circuit and a voicebroadcast circuit,etc,programmed in C language,and then combined with route planning fordesign verification.This design replaces the factory to design a special intelligent material and semi-finishedproduct distribution trolley for the production workshop.This design adopts the idea ofmodularity,the hardware and software modules of each module are designed,and then theassembly and system testing of the car body are carried out to basically achieve the expectedresults.Key words:Follow the trail,STM32,Obstacle avoidance
