PLC技术对医用气体分区计量、集中管理的应用研究

Application of PLC technique in measuring, remote meter reading and managing medical gas flow in hospital

采用气体质量流量计作为计量装置 ,运用PLC (电力线通信 )技术实现远程集中抄表 ,通过后台管理软件实现医用气体分区计量的远程自动抄表。

Medical oxygen flow of each district in a hospital is measured with mass flow meter The data is communicated through power line and concentrated at a place with a concentrator A PC set in somewhere can communicate automatically and periodically with the concentrator and get the data through telephone network The computer processes the data, displays and prints cost tables monthly, gives statistic graphs for later use
