EDUCON2018 17-20 April, 2018 Santa Cruz de Tenerife, Canary Islands, Spain VISIR Remind >>> what is VISIR? • Virtual Instrument Systems in Reality • VISIR is a remote laboratory for wiring and measuring electronics circuits on a breadboard • VISIR allows realizing real measurements on physical equipment with concurrent users • The entire equipment is controlled by LabVIEW server software • The wiring mechanism is developed by means of a relay switching matrix connected to a PCI eXtensions for Instrumentation (PXI)
- 5. EDUCON2018 17-20 April, 2018 Santa Cruz de Tenerife, Canary Islands, Spain VISIR Remind >>> what is not VISIR? • VISIR is not a simulation software or a virtual lab; there is a physical limitation since it does not allow an indeterminate number of concurrent users • VISIR is not a lab to carry out any type of experiment; for example, destructive experiments are not allowed because all experiments must be reusable • VISIR is not an instructor; The measurement server acts as an instructor to avoid hazard circuits but it lacks of assessment and evaluation for teachers or guidance for students

- 7. EDUCON2018 17-20 April, 2018 Santa Cruz de Tenerife, Canary Islands, Spain VISIR All VISIR nodes have a limitation on the available components and feasible circuits. This limitation derives from: • Limitation in the number of component boards installable (15 at most) • The components/shortcircuits allocated at each component board depends of the component board version (2, 10/16) • The available circuits depend on the design of the component boards real laboratory physical contraints

- 12. EDUCON2018 17-20 April, 2018 Santa Cruz de Tenerife, Canary Islands, Spain PILAR The federation of remote laboratories is a feature that RLMSs have started to support, providing management tools and managing common services: Two universities using the same RLMS support federation protocols. i.e. Go-Lab counts with remote and virtual laboratories from 18 institutions …but, each remote laboratory is considered as an individual entity. Two institutions providing the same remote lab can balance their clients/users load. This feature improves the users’ involvement in the remote lab environment due to the improved time response and availability. But in VISIR is not enough to share the lab, same experiments are also required. Federation

- Redundancy approach: scalability, reliability and availability at the expense of diversity. If one node is not available for any reason, its effort can be supported by other nodes. Diversity approach: Each VISIR node can specialize in a specific topic (component’s reusability in the matrix) This approach empowers experiment catalog at the expense of scalability and reliability. Combined approach: empowering scalability for those common experiments and dedicating each node in a specific area. Agreed-Shared approach: Each node has to design a percentage of their components boards based on the federation needs (redundancy, diversity or combined), and design freely the rest of component boards sharing the experiments with the partners.
