摘　　要：介绍一套集病区氧气流量测量,远程、自动抄表,流量数据处理,自动计费结算,打印报表等功能为一体的系统。该系统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、计费管理及数据分析。A system with functions of measuring oxygen flow of each district, reading flow meters remotely and automatically , processing flow data, accounting and prin. ring oxygen consumption, is introduced. The 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.
