基于Multisim的电子技术实验案例分析——以简易红外倒车雷达为例

Analysis of Electronic Technology Experiment Case Based on Multisim:Take Simple Infrared Reversing Radar as an Example

电子技术作为机械工程及自动化等非电类专业的必修课,要求学员在掌握扎实的理论知识基础上,还要具备一定的设计能力和实践能力。红外倒车雷达电路是基于Multisim的电子技术设计性实验,综合运用模拟电子技术和数字电子技术的相关知识设计电路,并完成硬件电路的焊接与调试,最终实现利用发光二极管点亮数量来判断倒车距离的功能。通过实验案例,不仅能够激发学员的兴趣,加深其对课内知识的理解,还能切实提高学员的工程实践能力,为后续课程学习、学科竞赛和毕业设计打下良好的基础。

"Electronic Technology"is a compulsory course for second-year undergraduates majoring in non-electrical engineering such as mechanical engineering and automation.Students are required to have certain design ability and practical ability on the basis of mastering solid theoretical basic knowledge.The infrared reversing radar circuit is a design experiment of electronic technology based on Multisim,which comprehensively uses the relevant knowledge of analog and digital electronic technology,complete the welding and debugging of hardware circuit,finally realize the function of using the number of light emitting diodes to judge the astern distance.Through experimental case,which can not only stimulate students'interest,and deepen their understanding of the knowledge in the class,but also effectively improve the students'engineering practice ability,lay a good foundation for subsequent courses,subject competitions and graduation design.
