基于红外通信的单片机实训平台的设计

在单片机实训教学过程中,通常使用单一模式化的实训项目,限制了学生的能动性,同时也不利于学生开阔视野,提供丰富的实训项目,充分尊重学生的兴趣爱好和注重个体差异,为实训教学提出了新的要求。从项目实训多元化的需要出发,以试卷保密为应用背景,利用单片机设计了基于红外通信的试卷保密箱系统,能够实现时间信息的传输和存储,通过严格控制试卷箱锁的开关时间达到对试卷保密的作用。实验证明,该系统可靠有效,能够较好地满足单片机实训多元化教学的需要。

Design of MCU training platform based on infrared communication

In the MCU practical training, usually use a single teaching project, which limited the ini- tiative of students and not conducive to expand their horizon. With fully respect the students＂ interests and pay attention to individual differences, a new requirement for the training teaching was proposed which need provided a more abundant training projects. To meet the need of the diversity of training and under the background of examination paper＇s secret work, in this paper, we designed a system of examination paper safe box for project training which can time calibration by infrared method , transmit and store time information. To keep the examination paper＇s safe by accurate control the unlock time of electric lock. Our experiments proved that the design of training project is very reasonable and fully meet the diversity requirements of MCU training.
