EVLAB WORKSPACE

Generic data acquisition software that gathers data as function  of time. Its layout consist of - an exploration window on the left, where all the available sensors are represented, together with the mathematical, graphical and table processing tools;
- a window at the bottom of the page for messages;
- a window on the right for parameters, with all information on the calibration of instruments;
- superimposable multiple windows in the center, for tools, charts and tables.
This software enables to select the sensors for gathering the data of each test, besides the tables for grouping these data and the charts for their representation. All these data are saved on disk so that they can be retrieved in any moment, without being programmed again. Tests can be carried out in various modes: manual mode, time mode or automatic mode. PHYSICS-EVLABDL-0
Each sensor is equipped with a tool of its own on the screen where the acquired quantities are displayed in real time. Ranges can be modifi ed (where possible) and other parameters concerning measurement can be selected. The spreadsheet enables to gather data automatically in tables. More spreadsheets can be opened at the same time and the quantities having to be inserted in each spreadsheet can be selected. Moreover, some formulae for processing the gathered data and obtaining other quantities can be added in spreadsheets. 3 types of chart can be plotted:

• chart in real time, that enables to display the quantities in graphic form, during their acquisition
•  “historical” chart that enables to display the quantities gathered and stored in the Datalogger or in a fi le on disk, in graphic form
•  chart from spreadsheet that enables to display the quantities available in the spreadsheet, in graphic form, and to select columns, axes of chart, fi elds of quantities, etc…

EVLAB WORKSPACE SPECIFIC FOR EACH EXPERIMENTS
For each one of the experiments presented in the Physics, Chemical and Biology catalogues, where the Datalogger and specifi c sensors are required, Elettronica Veneta has designed
specifi c softwares. Each software contains a didactic section, that explains:

•  the scientifi c principle to be demonstrated/experimented, the operative procedure for the preparation of the experiment, with demonstrative pictures and photos;
•  the acquisition of the experiment ‘data with graphics in real time; •  calculations to be realized on the basis of experimental data, to confi rm the principle studied;
•  questions and suggestions for students. The software becomes a valid support for the professor during the preparation of laboratory class.

AQ-2/EV simulator is part of a new set of educational equipment for the basic training on aircraft systems.

The simulator consists of a computer-assisted panel, with silkscreen mimic diagram for a clear location of its components. Various zones of the mimic diagram are represented with different colours to emphasize peculiar aspects of the system. Light and displays indicators, installed in the mimic diagram enable to assess the evolutions of the control.

The graphic display of the information available at the control input, such as aircraft status (park, APU...) on the computer screen enables the permanent monitoring of the system. The operational conditions are set by students according to the educational path indicated in the courseware, carried out by the PC.
