instrumentation and control using lab view ( national instrumentation lab view)

Submission Date: 14th November 2014 Assessment Value: 40%

This assignment is designed to work on a set of sampled data from a thickness sensor. The samples are stored in an appropriate array of up to 100 elements. The values represent the depth of the insulation around a particular cable. The thickness can vary from 0- 4 mm represented by a corresponding real value stored in the array. As long as the depth is between 1 and 4 mm the cable falls within the allowable specification however if it falls below 1 mm it is deemed to be too thin.

Specification 1 (60%)

To design a VI that will identify the number of thin values and display as a percentage of the total number of samples.

The front panel must have the following:

An array of controls holding the sampled values.

An indicator holding the percentage of thin values.

Specification 2 (80%)

Thin values tend to appear as sections or patches along the length of the cable i.e. values of less than 1 mm stored in successive array elements. To design a VI that will meet specification 1 and will also calculate the number of these thin patches. The front panel will now have an extra indicator to display the number of patches.

Specification 3 (100%)

To design a VI that will meet Specification 2 and will also be capable of detecting and displaying the start index and the length (number of successive elements less than 1 mm) of each thin patch.

Hint: Look at Array indicators.
