摘要本这一次的课程设计作品是选取了相对于其他单片机功能更加强大的STC12C5A60S2微控制器。这次的设计围绕着控制和微控制器相结合的重点，来进行制作和研究。为了能够使小车的运行程度正常，在成果展示的时候不出现相应的问题和困扰，经过考虑使用PT2262/2272无线控制模块，可以达到小车成功进行多个方向的前进，同样在寻轨的问题上可以达到有关的指标。同时LN298控制实现驱动电机配合单片机自带PWM调节实现智能小车在设定电磁导线轨道自动运行。77658

    整个电路的流程有四大主要的模块构成，其中的重点在于传感器的接受信号然后传达给检测的模块，经过微控制器的处理，可以用来控制小车的行动。若检测到电感信号即传输给比较器处理，由单片机发出寻轨电磁的指令，各个模块按指令执行模块功能。无论是遥控控制还是电磁寻轨，驱动模块芯片L298N只要接收到单片机给出的驱动指令，可以达到课程设计的基本目标。

The smart car based on Electromagnetic Tracking

Abstract The based on electromagnetic optimization of smart car rail used is enhanced 51 MCU STC12C5A60S2 chip, which has a self core control module。 The main function of this design is mainly automatic control combined with remote control, realize the running of car and automatic track seeking。 This time in order to realize the remote control to enable the car to realize the intelligent operation, so the selection of PT2262 / 2272 wireless control module, remote control car to achieve forward, backward, turn left, turn right, to control the car running on the track。 Also LN298 control drive motor with integrated in single chip PWM regulation of smart car electromagnetic wire track the set to run automatically。The whole circuit is a total of three modules, respectively is the detection control drive。 Detection can be pided into two parts, one is to test whether the implementation of remote control, if, the implementation of the remote control module is given the run command, the second is using electromagnetic induction signal induction module detects pavement, to detect if the inductance signal transmission to the comparing unit issued by the MCU in search of electromagnetic rail instructions, each module according to the instruction execution module。 Whether it is remote control or electromagnetic tracking, driving chip L298N only when they receive the driving instructions of SCM is given, you can run the motor drive to achieve the purpose of。
