检验、医疗设备与计算机串口连接的实现方法

Implementation method of connecting inspection and medical equipment with computer

上世纪90年代医院购买的电子仪器设备基本上不具备计算机智能化 ,随着计算机信息化网络化的飞速发展 ,多媒体信息管理系统已经成为衡量一个医院资质的主要指标 ,要将这些医用仪器设备的模拟信号变成计算机可以接收的数字信号是我们的当务之急。本文以AT89C51单片机为核心 ,采用TLC254312位串行A/D转换器 ,设计了一个串行数据采集/传输模块 ,给出了硬件原理图和主要源程序。

Medical electronic instruments and equipments, which the hospital bought in the 1990s, do not possess the intelligent function basically. With the high-speed development of informationization and networked of computer, the multimedia infromation management system have already become the leading indicator which measure the quality of a hospital. It is the task of top priority to change the analog signals of the medical instrument and equipment into the digital signals that the computer can receive. In this text, we choose microcontroller of Model AT89C51 as the target, adopt TLC2543 12 serial A/D converters and design a serial data collection / transmission module. The article gives the principle picture of the hardware and main source program.
