IoT Platform-based iAR: a Prototype for Plant O&M Applications

Abstract

In this paper, we present an iAR prototype designed for offshore/onshore plant's piping O&M. We have defined terms of iAR as “integrated-AR” and “intelligent-AR” in previous paper. That is, AR technology or application should be integrated with CAD system (or CAD oriented system) and be able to support engineering knowledge to be the successful industry application. The system uses “Intergraph Smart™ 3D for Plant” to export piping model data and “PTC ThingWorx” as IoT platform. The architecture of our prototype involves two main modules: converting pipe drawing data to 3D model and connecting sensor data to 3D model. The first module includes parametric piping symbol data generator, which can directly generate 3D geometry model from isometric piping drawing files. In the second module, we developed fast sensor data connecting methods for connecting sensor device with 3D model. By combining these processing modules, the proposed system is able to successfully apply to plant's O&M (operation and maintenance).
