分布式医用供气监控系统设计

Design of distributed medical gas supply monitoring system

基于集中管理概念,目前医用供气监控系统大多以通讯联机方式将各处气体监控报警器与中央监控联机,集中收集压力以及其他工作状态信息,并储存至数据库。中央监控通过收集到实时状态信息及数据库内的历史取样数据,在监控室或对外以无线传输方式提供异常报警及压力趋势图等信息。监控室亦可直接对报警器进行远距操控。有关信息读取及远程操控等各项功能均由中央监控管理。然而,系统若遭受外部影响丧失功能时,如断电或报警器联机中断,相关负责人员将无法自中央监控获得任何信息。医院或增加投资,增加后备系统,以防不测。本文介绍一种分布式医用供体监控系统,分散信息储存,降低系统风险。管理人员与操作人员能方便提取信息,做出正确的判断和应急处置,亦可降低系统成本。

Based on centralized management concept,medical gas supply monitoring system usually connects the monitoring and management center with distributed alarm devices via communication wires to collect and store running information such as physical values and alarm status.According to the real-time status information and the history log in the database,central monitoring room can give alarm or pressure trend figures to relevant responsible persons.Using remote viewer and control technology,the central monitoring room also can set up and control the parameters of the alarm devices.All information collecting and remote controlling functions are under the charge of the monitoring and management center.However,when damage caused by external forces disables the system,such as power or communication interruption,relevant responsible persons cannot receive any information from the monitoring and management center.In order to eliminate this risk,a backup system is applied to the monitoring and management center,which costs a lot of budget.This paper introduced a distributed medical gas supply monitoring system to lower system risk by distributed information storage.With the distributed medical gas supply monitoring system,management and operation staff can retrieve relevant information very conveniently and make a decision quickly to handle emergencies.Meanwhile,the cost of the system can be reduced.
