Specification of Maintenance Procedures for Protection and Automation Systems Using Augmented Reality
The usual maintenance procedures of protective and automation field devices of utilities are specified through scripts using text and images (photos and diagrams).These means of conveying information may lead to errors of misunderstanding caused by bad interpretation from the maintainer.Consequently,this causes delays and may require the redoing of maintenance,which is directly associated with increased maintenance runtime and cost.The outcome is associated with other problems that may lead therefore to damages to primary equipment,which may result in the interruption of power supply and electrical system blackouts.In order to mitigate these problems, some methods were investigated. They rely on the exposure of the necessary information of maintenance procedures aimed at reducing the cognitive gaps in the process of capturing maintenance instructions. In this context, an approach that transforms the maintenance scripts into increased itineraries was designed in a research project named CHESF Augmented Reality (CHESF-RA). In CHESF-RA, maintenance scripts are loaded in a software tool and objects in the physical environment around the computer that runs the tool are identified. When the target device under maintenance is found, the application will present instructions with additional visual information about where in the device each specified maintenance step will apply. In addition, the CHESF-RA is able to provide multimedia information and annotations on the procedure and requests information from the maintainer about the current operational state, providing a playful experience in performing the maintenance process. The CHESF-RA application can be used in the execution of any similar procedure following scripts for maintenance training and operation. In this context, CHESF-RA can be used as an interactive guide, simulating the tasks to be performed during the process. Any task describable in an instruction list format can be incorporated into the application. In other words, several areas of applications especially public utility services can explore the potential of CHESF-RA. This paper is organized as follows: Section 1 presents a brief introduction and contextualization of augmented reality concepts. Section 2 establishes the theory around mediated reality and its application in technical operations and image tracking. Section 3 presents the module responsible for editing maintenance scripts. Section 4 continues the description of the details of the module used for script display. The final step Section 5 describes a user case application of maintenance in a real IED (distance protection relay) and finally the conclusions are presented.
