基于教学做一体化教学模式的学生技能大赛实训平台实践研究——以嵌入式技术应用开发赛项为例

Practical Research on Training Platform of Student Practical Skills Competition Based on Teaching-learning-doing integration Teaching Mode——Take the Embedded Technology Application Development Competition as an Example

"教学做一体化"教学模式致力于培养学生的实践操作能力,通过学生技能大赛有效加强学生的职业技能训练。本文立足嵌入式技术应用开发赛项,针对嵌入式系统智能小车循迹过程中对地面标志物进行识别和检测,设计了一套以目标图形图像识别测控为主的系统。该系统以STM32F103VCT6处理器为核心,以直流减速电机为驱动实现小车车速和方向的准确控制,使用云台摄像头检测地面标志物,应用超声波传感器和红外传感器进行有效避障。

The teaching mode of"Teaching-learning-doing integration"is committed to cultivating students’theoretical knowledge and practical operation ability,promotes students to form good development trend of technology and skills.And effectively strengthens students’vocational skills training through students’skills competition.This research is based on the embedded technology application development competition,aim to recognize and detect of ground markers in the tracking process of embedded system intelligent car,to design a system based on target image recognition and control.This system takes STM32F103VCT6 processor as the core,and drives by DC gear motor to realize accurate control of car speed and direction,and use PTZ camera to detect ground markers,and to use Ultrasonic Sensor and Infrared Sensors for effective obstacle avoidance.
