摘　　要：云南华联锌铟股份有限公司质检中心为了减轻计量人员的工作量,针对计量员频繁跑现场记录取样数据的问题,进行了一种应用多种通信自动控制计量装置研究,通过西门子200系列的PLC S7-200 CPU224XP CN编写控制程序,将梅特勒-托利多IND231称重显示仪、矿浆缩分器、液位计、气动阀等控制信号显示在人机界面触摸屏MT8103IE上,桶加水(A)值、K值、实时质量调整值、原矿水分值、累计吨重值通过程序写入DCS控制系统中。通过自由口通讯协议、以太网通信协议、MODBUS通讯协议等完成通信互通的矿浆计量装置自动控制,得到了定时记录数据,应用到现场数据记录,提高了工作效率,减轻了员工劳动强度。In order to reduce the workload of the measuring personnel,the quality inspection center of Yunnan Hualian Zinc Indium Co.,Ltd.has carried out a research on the application of a variety of communi⁃cation automatic control metering devices for the problem that the measuring personnel frequently run on site to record the sampling data.The control program is written by Siemens 200 series PLC S7-200 CPU224 XP CN,and the control signals such as Mettler-Toledo IND231 weighing display,slurry divider,liquid lev⁃el meter and pneumatic valve are displayed on the human-machine interface touch screen MT8103 IE.Bucket water(A)value,K value,real-time quality adjustment value,raw ore moisture value and cumula⁃tive tonnage value are written into the DCS control system through the program.Through the free port com⁃munication protocol,Ethernet communication protocol,MODBUS communication protocol,etc.,the auto⁃matic control of the slurry metering device is completed,and the timing record data is obtained and applied to the field data record,which improves the work efficiency and reduces the labor intensity of the staff.
