Please Answer The Following Questions Explain Your Solution Clearly

Please answer the following questions. Explain your solution clearly. Your submission must clearly show the screen shots of Front Panel (while the VI is running), the Diagram Panel and clear explanation. 1a. Build a VI that generates a 2D array of three rows by 10 columns containing random numbers. After generating the array, index each row and plot each row on its own graph. The front panel should contain three graphs. 1b. Build a VI that continuously measures the temperature once per second and displays the temperature on a scope chart. If the temperature goes above or below limits specified with front panel controls, the VI turns on a front panel LED. The chart plots the temperature and the upper and lower temperature limits. You should be able to set the limit from the front panel.

Solution for Data Generation and Temperature Monitoring VI

Introduction

LabVIEW programming provides robust tools for data acquisition, processing, and visualization, enabling the development of dynamic virtual instruments (VIs). The described tasks involve creating two distinct yet interconnected VIs: one for generating, indexing, and plotting a 2D array of random numbers, and another for real-time temperature monitoring with visual alerts. This paper details the design, implementation, and testing procedures for both applications, illustrating best practices for visual programming in LabVIEW.

Part 1: Generating and Plotting a 2D Array of Random Numbers

Objective

Develop a VI that creates a 3x10 array of random numbers, extracts each row, and plots these on individual graphs within the front panel.

Design Approach

1. Array Initialization and Random Number Generation: Use the random number generator functions available in LabVIEW.
2. Array Construction: Build a 3x10 array by populating it row-by-row.
3. Indexing Rows: Extract each row separately using the 'Index Array' function.
4. Plotting Data: Use waveform charts for visualizing each row on the front panel.

Implementation Details

The block diagram begins with a loop that creates three rows, each populated with ten random numbers. A 'For Loop' iterates for each row, generating an array of ten random numbers using the 'Random Number (0-1)' function scaled appropriately. Each row array is stored in a 2D array. After generating the array, individual rows are extracted with 'Index Array' and wired to three waveform charts in the front panel, each configured to display one row.

Sample Screenshot

The front panel contains three waveform charts labeled 'Row 1', 'Row 2', and 'Row 3'. The block diagram shows the data flow and loop structures responsible for array creation and indexing.

Part 2: Continuous Temperature Monitoring with Limits and Visual Alerts

Objective

Create a VI that measures temperature once per second, displays it in real-time, and indicates when the temperature exceeds preset limits with a front panel LED.

Design Approach

1. Simulate or acquire temperature data; for simulation, use a random value generator within a realistic range.
2. Measurement Loop: Implement a 'While Loop' with a 1-second delay to emulate real-time sampling.
3. Display: Use a waveform chart for ongoing temperature data visualization.
4. Limits Adjustment: Include front panel controls (numeric inputs) for upper and lower limits.
5. Alert Indicator: Use a front panel LED that activates if temperature exceeds limits.

Implementation Details

The block diagram comprises a 'While Loop' that runs continuously, sampling temperature data every second. Random or sensor data feeds into a shift register to maintain a live data history, enabling plotting of temperature over time. The limits are controlled via numeric controls on the front panel. An 'If-Else' structure compares current temperature with set limits: if outside, it turns on the LED; if within, the LED remains off. The temperature data and limits are plotted together for context.

Sample Screenshot

The front panel displays a waveform chart labeled 'Temperature', two numeric controls for limits, and an LED indicator labeled 'Limit Exceeded'. The diagram illustrates the loops, data flow, and logic for alerting.

Conclusion

Both VIs demonstrate fundamental LabVIEW programming concepts including array manipulation, data visualization, real-time data handling, and user interface design. These applications highlight the ease of integrating data processing and visualization techniques to develop interactive virtual instruments. Proper implementation ensures accurate data representation and prompt visual alerts, enhancing system reliability and user awareness.
