- A demo prototype of a reconfigurable IEEE1451.0-compliant and FPGA-based weblabPublication . Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioA reconfigurable weblab prototype was designed according to the I E E E1451.0 Std. based on FPG As. A brief introduction about its architecture and underlying infrastructure is presented. After an overview about the main features of the weblab, namely the standard access and the reconfiguration capability, the proposed demonstration for the exhibition session is described.
- A customizable platform for remotely teaching & learning LVDTsPublication . Costa, Ricardo J.; Fernandes, Samuel; Jorge, Joni; Alves, Gustavo R.In electrical engineering, sensing natural phenomena requires the use of transducers, such as the sensors named Linear Variable Differential Transformers (LVDTs). They are traditionally interfaced with computer devices through signal conditioning circuits to measure linear displacements with good linearity, sensitivity and precision. Their adoption in many industrial applications requires from engineering schools a particular attention to create the best conditions to teach and learn them, in particular by providing infrastructures to enable students the conduction of experimental activities. To overcome some of the difficulties faced by engineering schools (low budget, curricula time constraints, lack of infrastructures, among others), this paper presents a remotely accessible infrastructure comprising a customizable platform that enables the conduction of real LVDT experiments. Since the infrastructure is currently a prototype solution, some improvements are suggested, in particular the possibility of using some of the issues described in the IEEE1451.0 Std. that was originally published to design and interface smart transducers.
- Embedding instruments & modules into an IEEE1451-FPGA-Based Weblab infrastructurePublication . Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, MárioAdopting standard-based weblab infrastructures can be an added value for spreading their influence and acceptance in education. This paper suggests a solution based on the IEEE1451.0 Std. and FPGA technology for creating reconfigurable weblab infrastructures using Instruments and Modules (I&Ms) described through standard Hardware Description Language (HDL) files. It describes a methodology for creating and binding I&Ms into an IEEE1451-module embedded in a FPGA-based board able to be remotely controlled/accessed using IEEE1451-HTTP commands. At the end, an example of a step-motor controller module bond to that IEEE1451-module is described.
