[Abstract]:An automatic tracking car system based on inductance sensor is designed in this paper. MSP430F169 is used as the main control chip, and the data is collected by inductance sensor to realize the automatic tracking function. The system is composed of optocoupler isolation motor driving module, deceleration motor module, buzzer sound prompt module, liquid crystal display module, encoder speed measuring module, Bluetooth module and battery module. The single chip microcomputer outputs variable pulse signals to drive the deceleration DC motor to control the steering and speed of the car, and the single chip microcomputer controls the track movement of the car by constantly scanning the data output from the four channels of the sensor. When the obstacle is detected, the single chip microcomputer controls the buzzer module to give out the sound prompt, the single chip microcomputer timer module realizes the accurate timing, and the encoder speed measuring device measures the real time speed of the car. The real-time running time and driving distance of the car are displayed on the LCD screen. The system has high design precision and low power consumption.
