基于ATmegal28的串行数据采集及控制系统的设计

Basis on the ATmega128Design of Serial Digital Collection and Control System

本文介绍了以单片机Atmegal2 8为核心构成串行数据采集及控制系统 ,该系统通过串行口与具备串行口的医疗设备通信 ,控制系统可发指令给医疗设备实现系统控制 ,控制系统同时通过A/D转换实现数据采集。系统利用单片机丰富的软硬件资源 ,可以实现采样、通讯、计算、脉冲计数等多种功能。实验表明 ,该方案系统电路结构简单、功耗低 ,特别适合基于单片机的便携式医学仪器开发。该系统已成功地应用于便携式静脉麻醉控制仪的开发。

This paper presents the single chip processor Atmega128 as the core,which forms the serial digital collection and control system:This system can take communication through serial nterface to the medical equipment,which has the serial interface.The control system can give order to the medical equipment to realize the system control.The control system can realize digital collection through A/D transition.The system can realize several functions of sampling,communication,calculation and pulse counting with an abundant of software and hardware of single chip processor.The experiment expressed that this system circuit of scheme with the advantages of simple in structure and lower in power consumption,especially to suitable to the development of portable medicine and medical apparatus based on the single chip processor.The system is successfully applied to the development of portable vein anesthesia controller.
