摘　　要：针对实际工程中不同软测量系统的需求,设计了具有可变辅助变量的通用性软测量集成系统软件。考虑到数据获取的实时性,使用OPC客户端获取在线数据;辅助的变量选择采用主元分析方法进行,并建立了具有一般性的数据处理模块;模型建立分别提供了常用线性、非线性以及多模型融合方法的模块,用户可按需求构建摸型;考虑到实际系统的时变性,系统提供了模型分析及模型校正功能,以确保用户使用中软测量系统模型的最优化及高精度的预测期望,该软件为生成实际工程需求的在线软测量系统提供了通用便捷的基础平台。Aiming at the current development of industrial soft measurement, in the case of variable auxil-iary variables, designs soft sensing software with universal property. Taking into account of the effectiveness of acquisition of the data, the OPC client is used to have an access to online data. Moreover, a principal compo-nent analysis method is used for choosing auxiliary variables,and it establishes a general data processing mod-ule. Model is used to provide a module of linear, nonlinear and multi-model fusion method, thus the user can build model for his own demand. In terms of the variability of the actual system, the system provides a model analysis and model calibration feature to ensure that users use a soft measuring system model optimization and highly accurate forecasts. The software provides an universal convenient base platform to generate the actual needs of online software engineering measurement system.
