BR-Sensor: An On-line Data-driven Soft Sensor of Downhole Pressure∗

In this work an object-oriented approach for implementing soft sensor components, encapsulated as dynamic-link-library (DLL), is proposed. A variety of models used for the estimation of a specific unmeasured process variable and implemented as DLL components is integrated to the soft sensor main component by simply following the interface described in this paper. In order to check the performance of the proposed approach a computational analysis is carried out. Although the main objective is to deploy the soft sensors into the supervisory the main ideas laid out here can be extended to other Windows-based solutions.
