Edge computing in SCADA in SCADA systems - Mini Project: Build & Apply

Edge Computing in SCADA

📖 Scenario: You work as a technician managing a SCADA system for a water treatment plant. The plant uses edge computing devices to collect sensor data locally before sending summaries to the central control system. This helps reduce network load and speeds up response times.

🎯 Goal: Build a simple program that simulates collecting sensor readings at the edge, filters important data based on a threshold, and prepares a summary report to send to the central SCADA system.

📋 What You'll Learn

Create a dictionary called sensor_readings with exact sensor names and their numeric readings.

Add a variable called threshold to filter sensors with readings above this value.

Use a dictionary comprehension to create filtered_readings with sensors exceeding the threshold.

Print the filtered_readings dictionary as the final output.

💡 Why This Matters

🌍 Real World

Edge computing in SCADA systems helps process sensor data locally to reduce network traffic and improve response times in industrial control environments.

💼 Career

Understanding how to filter and summarize sensor data at the edge is important for SCADA technicians and engineers working with modern industrial IoT and automation systems.

1

Create sensor readings dictionary

Create a dictionary called sensor_readings with these exact entries: 'temp_sensor': 72, 'pressure_sensor': 45, 'flow_sensor': 88, 'level_sensor': 30.

SCADA systems

# Create the sensor_readings dictionary with the given sensor names and values
# Your code here

Need a hint?

Use curly braces {} to create a dictionary with the exact sensor names as keys and their readings as values.

2

Add threshold variable

Add a variable called threshold and set it to 50 to filter sensor readings.

SCADA systems

sensor_readings = {'temp_sensor': 72, 'pressure_sensor': 45, 'flow_sensor': 88, 'level_sensor': 30}
# Add the threshold variable with value 50
# Your code here

Need a hint?

Just create a variable named threshold and assign it the number 50.

3

Filter readings above threshold

Use a dictionary comprehension to create a new dictionary called filtered_readings that includes only sensors from sensor_readings with values greater than threshold.

SCADA systems

sensor_readings = {'temp_sensor': 72, 'pressure_sensor': 45, 'flow_sensor': 88, 'level_sensor': 30}
threshold = 50
# Create filtered_readings dictionary using comprehension
# Your code here

Need a hint?

Use {sensor: value for sensor, value in sensor_readings.items() if value > threshold} to filter the dictionary.

4

Print filtered readings

Print the filtered_readings dictionary to display the sensors with readings above the threshold.

SCADA systems

sensor_readings = {'temp_sensor': 72, 'pressure_sensor': 45, 'flow_sensor': 88, 'level_sensor': 30}
threshold = 50
filtered_readings = {sensor: value for sensor, value in sensor_readings.items() if value > threshold}
# Print the filtered_readings dictionary
# Your code here

Need a hint?

Use print(filtered_readings) to show the filtered dictionary.
