摘　　要：为了培养低年龄段学生逻辑思维能力,少儿编程课程中常常采用智能循迹小车路径规划课程体系。目前市场上编程教具智能循迹小车大多采用颜色传感器及颜色指令贴纸进行小车运行方向控制,但颜色指令贴纸容易撕毁,很难重复利用,同时颜色传感器受环境影响较大,识别精度低,针对传统编程小车弊端,该文设计了一种基于RFID技术的射频指令卡编程小车,利用射频识别传感器和射频指令卡进行小车路径方向的控制与识别,通过多次实验测试,射频指令卡在九宫格路径上可任意移动和重复使用,能够很好地控制编程小车在九宫格上的行进方向,相较于传统颜色指令贴纸,响应速度快,识别精度高达99%。In the children’s programming enlightenment course,the smart car path planning mostly adopts the control mode of color recognition,but the color instruction stickers cannot be reused. At the same time,the color sensor is greatly affected by the environment and the recognition accuracy is low. Therefore,a design based on RFID technology is designed in this article. The instruction card programming trolley uses a movable instruction card to replace the traditional stickers,which better realizes the tracking and planning of the nine-square grid path. The response speed is fast,and the recognition accuracy is up to 99%.
