遥控电动小车装置的设计制作摘要本遥控小车装置是采用凌阳61单片机作为主控制器，利用nRF2401无线通信模块实现实时通信，以满足使用遥控器实时控制小车的目的（通过无线遥控器的控制实现小车的前进、转向、倒退等动作）。遥控器键盘采用4×4键盘设计；小车电机驱动采用L298电机驱动芯片；遥控器显示屏应用LCD12864液晶显示模块。单片机输出两路PWM波控制L298N驱动小车行走。通过无线遥控控制小车行走不同轨迹，使小车找到目的地。由于要实时显示小车的具体、准确的位置，所以我们通过测量小车走过的路程，进而确定小车的坐标，并以小于0.5秒的速度刷新坐标。整个控制系统电路结构严谨，实用性强，可靠性高，稳定性好。经测试本系统的实验测试结果满足题目各项要求，实现了智能小车的设计与制作。关键词：SPCE061A单片机L298驱动无线遥控技术AbstractTheremotecontrolelectriccardeviceistousetwopiecesofsunplus61singlechipmicrocomputerasthemaincontroller,usingnRF2401wirelesscommunicationmoduletorealizereal-timecommunication,inordertomeetthereal-timecontrolusingaremotecontrolcarpurpose(completeuseofwirelessremotecontroltorealizethecarforward,steering,back).Theremotecontrolkeyboardusing4x4keyboarddesign;CarmotordrivetheL298motordriverchip;TheremotecontrolapplicationdisplayLCD12864liquidcrystaldisplaymodule;Thecarspeedbysingle-chipmicrocomputeroutputtwowayPWMwavetocontroldriveL298Nfinished,becausetheapplicationofhighperformanceL298Nchipmotordrive,makesthemotorspeedstability;Themotortocontroldcmotor,throughthewirelessremotecontrolcarwalkdifferenttrackroute,makethecarfindarriveatthedestinationrouterecently.Duetodisplaythecarofthespecific,accurateposition,soweusedphotoelectricpipemeasuringcarpassesthroughthejourneytodisplaythecaroftheactualcoordinates,andmeettherefreshrateislessthan0.5seconds.Thewholecontrolsystemcircuitstructureisrigorous,practicalstrong,highreliability,goodstability.Accordingtothetest,thesystemoftheexperimenttestresultsmeettherequirementssubjectandrealizetheintelligentcardesignandproduction.Keywords:SPCE061AL298drivewirelessremotecontroltechnologyTOC\o"1-3"\h\z\uHYPERLINK\l"_Toc335663870"一系统整体方案PAGEREF_Toc335663870\h3HYPERLINK\l"_Toc335663871"二方案论证与比较PAGEREF_Toc335663871\h4HYPERLINK\l"_Toc335663872"1单片机的选择PAGEREF_Toc335663872\h4HYPERLINK\l"_Toc335663873"2电机驱动的选择PAGEREF_Toc335663873\h5HYPERLINK\l"_Toc335663874"3通信模块的选择PAGEREF_Toc335663874\h5HYPERLINK
