摘　　要：纤膏总量是材料成本的分析依据之一。为节支降本、精确制造,研发纤膏流量计量控制系统监测并控制纤膏输出的实时流量,保证产品质量。纤膏流量在线监测系统采用夹钳式流量传感器,监测流量时间和流速,配套软件通信,实现生产过程纤膏瞬时流量和累积流量的实时采集与计算,提升纤膏利用率。结果表明,基于流量在线计量控制,当正常生产中无纤膏时系统可实时报警并记录缺陷位置;通过基础数据采集及运算,可实现纤膏流量闭环控制,降低了纤膏单耗,节省了原材料的用量;通过生产管理系统与控制系统连通,实现了数据应用分析。Total amount of fiber paste serves as one of the analytical bases for material costs.For cost-saving and precise manufacturing,flow measurement control system for fiber paste was developed to monitor and control real-time flow output of fiber paste,to ensure product quality.By using clamp type flow sensors,with software communication as supporting,the online monitoring system for fiber paste monitored flow time and flow rate to achieve real-time collection and calculation of instantaneous and cumulative flow of fiber paste in the production process,improving the utilization rate of fiber paste.Results showed that based on online flow measurement control,the system could provide real-time alarms and record the location of defects when there was no fiber paste in normal production.By collecting and calculating basic data,closed-loop control of fiber paste flow could be achieved,fiber paste consumption could be reduced and raw material consumption could be also saved.By connecting production management system with control system,data was uploaded to database,which could realize data application analysis.
