Advanced analytics and predictive maintenance in SCADA systems - Mini Project: Build & Apply

Advanced Analytics and Predictive Maintenance in SCADA Systems

📖 Scenario: You work as a technician managing a SCADA system that monitors machines in a factory. You want to analyze sensor data to predict when a machine might fail. This helps schedule maintenance before breakdowns happen, saving time and money.

🎯 Goal: Build a simple program that stores sensor readings, sets a threshold for warning, filters readings that exceed the threshold, and then displays those critical readings for maintenance action.

📋 What You'll Learn

Create a dictionary called sensor_readings with machine IDs as keys and their temperature readings as values.

Add a variable called warning_threshold set to 75 to mark high temperature alerts.

Use a dictionary comprehension to create alerts containing only machines with readings above the threshold.

Print the alerts dictionary to show machines needing maintenance.

💡 Why This Matters

🌍 Real World

Factories use SCADA systems to monitor machine health. Predictive maintenance helps avoid costly breakdowns by fixing machines before they fail.

💼 Career

Technicians and engineers use these skills to analyze sensor data and automate alerts, improving factory efficiency and safety.

1

Create sensor readings dictionary

Create a dictionary called sensor_readings with these exact entries: 'MachineA': 68, 'MachineB': 82, 'MachineC': 74, 'MachineD': 90, 'MachineE': 60.

SCADA systems

# Create the sensor_readings dictionary with given machine temperatures
# Your code here

Need a hint?

Use curly braces {} to create the dictionary with the exact machine names and temperatures.

2

Set warning threshold

Add a variable called warning_threshold and set it to 75 to mark the temperature above which maintenance is needed.

SCADA systems

sensor_readings = {'MachineA': 68, 'MachineB': 82, 'MachineC': 74, 'MachineD': 90, 'MachineE': 60}
# Set the warning_threshold variable to 75
# Your code here

Need a hint?

Just assign the number 75 to the variable named warning_threshold.

3

Filter readings above threshold

Use a dictionary comprehension to create a new dictionary called alerts that includes only the machines from sensor_readings with temperature readings greater than warning_threshold.

SCADA systems

sensor_readings = {'MachineA': 68, 'MachineB': 82, 'MachineC': 74, 'MachineD': 90, 'MachineE': 60}
warning_threshold = 75
# Create alerts dictionary with machines having readings above warning_threshold
# Your code here

Need a hint?

Use {machine: temp for machine, temp in sensor_readings.items() if temp > warning_threshold} to filter.

4

Display alerts

Write a print statement to display the alerts dictionary showing machines that need maintenance.

SCADA systems

sensor_readings = {'MachineA': 68, 'MachineB': 82, 'MachineC': 74, 'MachineD': 90, 'MachineE': 60}
warning_threshold = 75
alerts = {machine: temp for machine, temp in sensor_readings.items() if temp > warning_threshold}
# Print the alerts dictionary
# Your code here

Need a hint?

Use print(alerts) to show the filtered machines.
