SUPER-1生物医学信号智能处理仪的研制及应用

本文介绍一种以微机为核心的智能生理实验仪的研制。该智能仪接口硬件尽可能按微机接口板原理设计。软件的设计以记忆示波为基本软件,通过安排—功能扩展接口程序,而使多种生理实验专用软件挂接在记忆示波软件上运行。软件与硬件充分配合,实现了微机对信号增益、采样速度等参数的闭环控制。该智能仪可同时取代示波器、记录仪、刺激器而完成生理实验。     

的研制及其应用

生物医学中的各类电信号广泛的用于科研、临床及教学实验等领域申。然而这些信号的采集及显示更多的是用示波器、记录仪完成的。由于器件及性能的原因,它们对波形的存储、再显、重叠显示及分析等不能提供更多的帮助。若能利用计算机快速、存储容量大及计算功能强等特点自动的实现这些功能,无疑对生物医学工作者是大有帮助     

SUPER—1生物医学信号智能处理仪的研制及应用

Research work for making a biomedical signal processing instrument based on the APPLE-II computer is reported in this paper. According to the theory of the computer, two interface boards were designed as the hardware of the instrument. The memorizing waveform program was designed as the main program in the software system. Through a functional extended program, also called software inter face, more than ten programs especially for physiology can be easily linked to the main program. with the combination of both the software and hard ware several parameters of the instrument, such as sampling speed, gain of the amplifier, etc. can be controlled by a closed loop. This instrument is available in the physiology laboratory to replace oscilloscope, recorder, stimulator simultaneously. The functions of the instrument are stronger than those of the conventional instruments.
