针对软测量技术的应用问题，设计了基于OPC通信技术的解决方案。服务器站与操作站独立运行，服务器站计算机与控制系统连接，进行现场数据采集与软测量模型计算，计算出目标变量，并将结果反馈给控制系统，再由OPC服务器发送。操作站计算机通过工业以太网与服务器站计算机连接，利用OPC客户端与OPC服务器进行数据交换，实现对目标变量的监控。将该方案应用于氯乙烯聚合过程聚合速率与单体转化率的在线检测中，运行结果表明该方案稳定可靠。

For the application of soft measurement technology , the OPC technology-based method was de-signed.This method contains a server station and an operator station which operating independently .The serv-er station connecting with control system can read online data , calculate target variables through the soft meas-urement model and can write values into control system before having results fed back to the control system and sent via OPC server .The operator station connecting with server station via the industrial Ethernet can ex-change data with OPC server through OPC client so as to monitor target variables .Applying this method to on-line monitoring reaction rate and conversion of a vinyl chloride polymerization process proves the stability and reliability of this method .
