袖珍式生理信息采集器的研制

The research on pocket physiologic information acquisition device

目的 :解决生理信息测量时数据采集及取代磁带模拟的记录方式。方法 :利用大容量非易失性可电擦除的存储器存储生理信号的数字信息。结果 :采集的信号经通用前置放大器处理后由ADμC812内部A/D转换器转换为数字信号 ,在液晶显示器的监视下存入数据存储器。结论 :数据容量大、信号失真小、携带使用方便。

Objective: Solving physiologic information acquisition and replacing logging mode of magnetic tape analogue recording.Methods: Making use of large capacity and non - volatile memory store digital information about physiologic signal.Results: After the detecting signal is processed by general pre - amplifier, it is transfered to digital information by A/D converter. The digital information is stored to memory in liquid crystal displays surveillant.Conlusion: Digitaldatum capacity is large,signal distortion is little,take and use facilelitaty.
