摘　　要：为改善微弱生物信号处理,构建了微弱电信号检测分析实验平台。依托专业在相关科研领域的优势,自行开发了精密信号调理电路、多通道接口电路和数据处理系统,将多台高性能微弱信号处理仪器连接为一个综合平台,在统一操作界面的控制下,对MEMS生物芯片或MEMS物理传感器中的微弱信号进行检测,或对学生自研的电路进行测试、诊断和评估。系统采用开放式结构,可以继续扩展新接口、暂时屏蔽部分功能、临时设置特殊行为或模拟产生各类故障,真正将抽象概念或理论与生动的实际联系起来,培养学生解决复杂问题或排除隐蔽故障的能力,实现交互式自主实验,满足多样性教学需求,为多门课程提供良好服务。An experimental platform for weak electric signal detection and analysis was constructed in which several high-performance weak signal processing instruments were integrated and controlled by a universal operation interface.This platform can not only detect signals from MEMS biological chips or MEMS physical sensors,but also test,diagnose and valuate circuits designed by students.The platform adopts an open architecture,therefore,new interfaces can be expand to it,some functions can be instantly screen of it,some special behaviors can be set on it.Besides,it can simulate faults of different kinds.Moreover,it can connect abstract concepts and theories with vivid practices,which helps students to develop complex problem-solving skills.Furthermore,it can realize interactive autonomous experiment,thus meeting various needs in teaching and providing good serves for several courses.
