高校电子实验数字集成电路检测仪的设计

在高校教学中,电子技术是专业基础课,大量理工科院校课程体系中均设置电子实验、电子工艺实习以及电子课程设计等实践教学环节和内容。课内电子实验和课外科技创新活动中常常遇到IC电路芯片表面标识不清,无法识别其型号,或外观正常但电路内部已损坏等情况。有时做了大量实验后得不到预期数据和正确结果,有时焊接制作好电子成品但不能实现既定功能,最后查出是所选用的IC电路芯片型号错误,或者是芯片自身故障,耽误了时间,降低了效率。以单片机为核心器件,搭建外围电路,建立科学的故障模型,开发一款便携、价廉、精准的数字集成电路的自动检测仪器,可用于大学生电子实验课、电子竞赛、科技创新活动、课程设计、毕业设计以及电子产品装配、电器维修、科研等其他相关领域,用途广泛。

Electronics technology is a basic professional course. Many universities and colleges open such contents as electronic experiments, electronic process practice and curriculum design. Students often face much inconvenience, for example, unclear IC chip label, Unrecognized mark and seemingly good but actually unusable. This leads to that even doing much work but not to get expected results, which waste much time and reduce efficiency. In order to resolve this problem, this paper use MCU as core component, construct circuit, build fault model, develop a portable, low-cost and precise and auto-detecting digital Integrated circuits, instrument. This instrument can be widely used in these fields which includes electronic experiment, electronic contest, scientific innovation, electronic product assembly, Electrical maintenance and research.
