摘要
智能小车以STC12C5A60S2单片机为控制核心,采用反射型光电探测器RPR-220对白纸中的黑色路径进行探测,按照预定的路径行驶,小车运用短距离无线通信模块NRF24L01将行驶状况传输给计算机;计算机运行VB软件设计的人机交互接口软件显示小车行驶状况,它还可通过微软的Speech SDK5.3识别操作者发出的语音指令,对小车进行控制。实验结果表明小车工作稳定,能够自主寻迹与避障,操作者可以遥控小车的行驶速度与方向。
This kind of intelligent car takes single chip microcomputer STC12C5A60S2 as the core,detects the black path on white paper by reflection type photodetector RPR-220,drives follow predetermined way.The car is able to transfer its data of running status to computer via short distance wireless communication module NRF24L01,the computer runs software of human-machine interface made by VB to display driving conditions of the car,it also can control the car through operator＇s voice command which recognized by Speech SDK5.3 of Microsoft.The experiment result shows that the car works stably,takes the function of self-tracking and obstacle avoidance,the operator can remote control the car＇s speed and direction.
