摘要
传统的遥控小车经过发展已经实现蓝牙无线操控,但电动小车在功能上仅限于前进、后退、简单旋转和加减速等简单操作,本系统针对此,以单片机为控制核心,采用霍尔传感器实时采集车轮转速和方位信号,根据信号的变化可随时调节控制电机的PWM及位置信号,系统不仅实现了简单的加减速功能,同时还能实现电动小车测速、调速、监速报警、稳速,并实时稳定显示速度和里程功能。系统稳定可靠、抗干扰能力强、成本低、使用方便。
After the development of traditional remote control car has Bluetooth wireless control, but the electric car in the function is limited to move forward and backward, simple rotation and deceleration etc. this system has the advantages of simple operation, therefore, to control the mieroeontroller core, using real-time acquisition speed sensor wheel Holzer and azimuth signal according to the signal changes in the regulation of PWM and the position signal to control the motor at any time, the system not only realized the simple acceleration and deceleration function, but also can realize the electric car speed, speed, speed, speed alarm monitoring, real-time and stable display speed and mileage function. The system is stable and reliable, strong anti-interference ability, low cost and easy to use.
