设计针对小车的智能控制和应用,提出了以蓝牙收发方式及微控制器实时控制,通过上下位机的控制设置,使小车能够在遥控模式和循迹模式切换。在遥控模式下,通过按键设置及蓝牙的发送和接收数据,实现了小车在遥控下直行、左右转、加减速、避障等功能。在非遥控模式下,小车可以沿着黑色的曲线行驶完成循迹功能。整个系统设计合理,工作稳定、性能良好、易于实时控制,是主流的智能化应用的产物,有广范的应用领域和发展前景。 The design aims at the intelligent control and application of the car, and puts forward the real-time control of the receiving and sending system of Bluetooth and the micro-controller by the control setting of the upper and lower computer so that the car can switch between the remote control mode and the tracking mode. In the remote control mode, through the key set and Bluetooth send and receive data, to achieve the car in the remote control straight, left and right turn, acceleration and deceleration, obstacle avoidance and other functions. In non-remote mode, the car can follow the black curve to complete the tracking function. The entire system design is reasonable, stable work, good performance, easy real-time control, is the product of the mainstream of intelligent applications, a wide range of applications and development prospects.
