Design And Implementation Of Smart Mobile System

In recent years,due to the limitation of urban traffic carrying capacity with high consumption,low conversion,heavy pollution.The development and improvement of new energy vehicles and related ancillary facilities and products was mentioned in the“Thirteenth Five-Year Plan” in energy conservation and emission reduction programs.Two-wheel self-balanced vehicle is suitable for the use in "last mile" travel and individual soldier monitoring in harsh environments,which has the characteristics of low energy consumption,small size,no harmful gas emissions,and flexible movement.In this paper,the two wheeled self balancing robot based on STM32 is studied.the system's hardware and software design was focused on this article.A mechanical frame was build based on Lagrangian mechanical structure.In hardware aspects,STM32F103C8T6 act as a core controller,including the main control board,MPU6050 gyroscope,optical encoder speed disk,ultrasonic and infrared laser pulse speed combination module,motor drive TB6612 FNG,Bluetooth module and other components,the mainstream PC configuration,Android phone as the host computer monitoring and remote control center.The collection and transmission of roadblock information,Bluetooth communication program,HJPH370 mobile phone remote control program are included to be signed in software.Fuzzy logic algorithm,neural network method,genetic sequence method,adaptive proportional differential integration method as a smart car steering control method.According to the prototype itself,combining fuzzy adaptive and PID algorithms,the overall operation is simple,the response is fast,and the real-time performance of system resources is saved.The experimental results show that: real time operating system RT-has good real-time performance,and it can run stably for a long time;With smoother operation,real-time response friendly.compared to traditional single PID control,the system hasstable operation and good dynamic characteristics,which provides high precision attitude information for the smooth running of the vehicle.,which meet the design requirements.
