Abstract
In order to realize the rapid and stable automatic tracking of the smart car, this paper designs and implements a tracking smart car with wireless communication function in the background of the National College Students Smart Car Competition of China. The system of the smart car includes hardware design, signal processing, and software algorithms. The hardware design mainly includes track information acquisition sensors, auxiliary control modules and communication modules. The software algorithms mainly includes the filtering and difference-ratio-sum algorithm, incremental Proportion Integration Differentiation (PID) and communication control algorithm. Firstly, the electromagnetic signal in the track is acquired by the inductance-capacitor pairs, and the deviation between the actual position of the smart car and the position of the electromagnetic wire laid in the central track is calculated. Then, the incremental PID control algorithm is used to calculate the pulse width modulation (PWM) signal according to the deviation, and the PWM signal is acted on the motor to drive the smart car to always drive along the central track, so as to achieve the purpose of automatic track guidance. The wireless communication module is used to achieve the communication between the two smart cars. Finally, a large number of hardware and software tests are carried out using the upper computer debugging tools. Experiments demonstrate that the smart car of this design can complete the communication task of two cars, can accurately achieve automatic tracking, and obtain higher speed performance.
