Smart car design and implement based on SCM AT89C55 application
A microcontroller AT89C55 was used as the detection and control core of the electric car passing seesaw in the design.Reflective photoelectric switch LTH 1550-01 constitute the patrol line module to guide the car driving; High-performance magnetic sensitive precision small-angle tilt sensor WQH36-45 was used to detect the state of equilibrium of the electric car; Bridge driver L298 was used to control reversing/forwarding rotation and PWM motor speed control; 12-bit switched capacitor successive approximation ADC TLC2543 was used to sample electric cars sensor signal; keyboard and LED display composed of I2C interface keyboard and LED driver ZLG7290 achieve the human-machine interface; voice playback was compose of the single-chip voice chip ISD2590 and small power amplifier LM386.Based on the above complete and reliable hardware circuit design,the use of sophisticated software algorithms to achieve the angle offset feedback loop speed control and self-correction,the exact line inspection guide,making the electric car in various stages can be accurately controlled.
