iLAB Experiment Engine Design Using LabVIEW

The iLab Shared Architecture (ISA) is a web services based software framework that aims at providing access to online laboratories assuming that they share some characteristics.The Service Broker is the core of the architecture and provides user authentication, authorization, experiment data storage and access to scheduling services. The lab clients and lab servers are lab domain specific.

Batched Lab Servers
Batched Experiments are those experiments that can have
their entire course specified before execution. The task of
performing a batched experiment can be summarized in
submitting an experiment protocol, executing the experiment,
retrieving and analysing the results.

LabVIEW
National Instruments’ (NI) LabVIEW is popularly deployed software for academic and industrial application. It is easy to control a real time process with NI’s graphic interface, hardware and drivers. DataSocket, an Internet programming technology included in the LabVIEW package, simplifies real time data exchange among computers connected through network.

LABVIEW BASED LAB SERVER DEVELOPMENT
In other existing batched labs the execution of an experiment is the task of a separated piece of software named experiment engine which was mostly developed with c#, c++. Basically it keeps checking the database for unexecuted experiments. As soon as if finds one it fetches the experiments specification parameters and execute the experiment. The results are written back in the database and are
fetched by the Service Broker via the Web services interface.

Since most engineers have little knowledge of text based language, and with the power of labVIEW graphically programming which is easily usable, we have been able to create a modified version of this Engine.
Easily Editable and learn

Virtual and Remote Laboratories

Virtual and Remote Laboratories

 The Internet technology has provided additional teaching strategies, with online education being one of the most exciting enhancements. A particular challenge for online education in engineering is how to extend the traditional hands-on laboratories to the Internet. Currently, there are two approaches to conducting labs
online, virtual and remote labs. VIRTUAL LAB is based on software to simulate the lab
environment while REMOTE LAB, by definition, is an experiment which is conducted and
controlled remotely through the Internet. These experiments use real components or
instrumentation at a different location from where they are being controlled or
conducted.

Hookes Goals....

• Scaling usage of online labs to a large number of
  users
• Encouraging researchers and universities to
  share their labs online
• Single sign on to labs at multiple universities
• Allowing universities with diverse network
  infrastructures to inter-operate and share
  resources.
• Allowing Organization and Users to access the laboratory anywhere they are.
