[摘要]
目的:研制一种利用无线路由 GPRS 传输、具有实时在线远程监测功能的氧气浓度中心监控系统,该系统可满
足各大医院的氧气浓度自动集中监测和提前预警,并可与外部互联网及内部局域网形成数据共享。方法:结合成熟的
GPRS 模块和单片机技术,采用多点循环访问和冗余数据侦测手段, 使分机的有效数据打包上传至内外网, 然后在监
控端利用可视化界面编程软件 和 Visual C++ 编写底层握手协议,将互联网的数据解包并逐一分解成所需对应
信息显示。结果:实践表明, 分别链接局域网和外网后, 经过与现场分机比对, 院内外的监控端均能实时显示对应浓
度,低于指定的阈值则给出预警提示。结论:该监测系统(含分机)性能稳定,不受距离和复杂电磁环境的影响,全天候
响应,实现了中心供氧的自动化和智能化,为医院气体的综合化管理做出了基础研究和初步探索。

Abstract
Objective To develop an oxygen concentration center monitoring system with the function of online remote
monitoring in real time transmitted by wireless GPRS in order to meet the demands of automatically focused monitoring and
early warning of oxygen concentrations in large hospital, and data sharing between external and internal LAN.
bined with mature GPRS modules and single -chip puter technology, using multipoint circulation
access and redundant data detection methods, the extension effective data were packed and uploaded to internal and
s, and then the
