The automotive chassis serves as the fundamental structural framework of a vehicle, bearing the car body, power system, suspension system, and other critical components. Typically constructed from steel or aluminum alloy, the chassis provides strength and rigidity to the vehicle. The suspension system includes shock absorbers and springs, responsible for cushioning road vibrations and enhancing driving comfort and stability. The braking system employs hydraulic or pneumatic design to ensure rapid and safe deceleration or stopping. The steering system allows precise control of the vehicle's direction. Modern vehicles increasingly incorporate electric power assist functions to enhance driving control.

The client's existing chassis production line faced several operational challenges:

• Limited automation: Manual intervention was required at multiple production stages
• Inconsistent quality control: Difficulty maintaining uniform standards across production batches
• Slow response times: Delays in detecting and addressing production anomalies
• Integration complexity: Disparate systems operating independently without centralized control
• Scalability constraints: Difficulty adapting to increased production demands or new vehicle models

The client deployed Siemens S7-1200 PLC integrated with DECOWELL's proprietary I/O modules to establish a comprehensive automation system for chassis production equipment control.

Multi-Sensor Integration The system seamlessly collects signals from various sensors including:

• Vehicle speed sensors
• Brake pressure sensors
• Position sensors
• Temperature sensors

These sensors provide real-time data, enabling the chassis system to autonomously make judgments and adjustments.

Centralized Control Architecture The PLC-based I/O modules manage multiple critical loads:

• Electric motors
• Hydraulic cylinders
• Pneumatic valves
• Brake systems

• Controller: Siemens S7-1200 PLC
• I/O Interface: DECOWELL custom I/O modules
• Communication Protocol: Industrial Ethernet for real-time data exchange
• Sensor Network: Distributed sensor array with centralized data processing

1. Enhanced Production Efficiency
