Automating Factory Truck Exit Using Industrial Automation

WHEN 5 TRUCKS COMES OUTSIDE A FACTORY AN INDICATOR 

SHOULD ON. WHEN ALL THE TRUCKS COMES OUTSIDE THE

FACTORY EXIT GATE SHOULD CLOSE WITH A CONDITON THAT

THERE ARE 10 TRUCKS PRESENT PREVIOUSLY INSIDE THE

FACTORY. 

In modern factories, automation plays a crucial role in optimizing efficiency and safety. One such automation scenario involves controlling the factory exit gate based on truck movement.

Scenario

• A factory initially has 10 trucks inside.
• When 5 trucks exit, an indicator turns ON to signal truck movement.
• Once all 10 trucks have exited, the factory exit gate automatically closes to ensure no further movement.

Implementation in PLC

This logic can be implemented using a Programmable Logic Controller (PLC) with the following approach:

1. Truck Count Monitoring: Use a counter to track the number of trucks inside the factory.
2. Indicator Control: A condition checks if 5 trucks have exited, turning on an indicator.
3. Exit Gate Control: Once all 10 trucks have exited, the exit gate receives a close command.

Ladder Logic Concept

• Counters: To track the truck count.
• Compare Instructions: To check when 5 and 10 trucks have exited.
• Output Coils: For turning ON the indicator and closing the gate.

Conclusion

This automated approach ensures smooth truck movement, enhances security, and reduces manual intervention. Industrial automation with PLC & SCADA can be further expanded for real-time monitoring and analytics.
