ARM-Based Controller for Vertical Parking System Solution
Case Details
ARMxy Controller Vertical parking system with a focus on precise lift control, reliable position detection, and seamless integration with billing systems. The design leverages high-performance ARM architecture, modular I/O boards, and remote debugging capabilities to ensure efficiency, adaptability, and scalability.
System Configuration
ARMxy Main Controller: Serves as the core processing unit, handling real-time control tasks and communication.
Y-High-Speed Pulse Board: Outputs AB-phase pulses to drive the servo motor for lift control.
X-DI Board: Detects leveling and anti-fall signals for precise position feedback.
Communication: RS485 interface for data exchange with the billing system.
Software: OpenPLC for programming and BLRAT for remote debugging and parameter tuning.
Implementation Method
Lift Control via Y-High-Speed Pulse Board
Pulse Output: The Y-board generates AB-phase pulses at a frequency of 100 kHz to drive the servo motor, ensuring smooth and precise vertical movement across 12 layers.
Control Logic: The ARMxy controller, programmed via OpenPLC, manages pulse generation to adjust lift speed and position based on real-time requirements.
Adaptability: Pulse parameters (frequency, duty cycle) can be remotely tuned via BLRAT to accommodate varying lift heights or motor specifications.
Position Detection and Closed-Loop Control
X-DI Board: Monitors leveling sensors and anti-fall safety signals in real time. Supports mixed voltage inputs (e.g., 5V–24V) for compatibility with diverse sensor types.
Closed-Loop Control: The ARMxy controller processes DI signals to validate lift position, ensuring accurate alignment at each layer. Feedback from the X-DI board enables precise stopping and error correction.
Safety Mechanisms: Anti-fall signals trigger immediate halt commands to prevent accidents, with configurable thresholds for enhanced reliability.
Integration with Billing System
RS485 Communication: The ARMxy controller interfaces with the billing system via RS485, enabling real-time data exchange (e.g., parking slot status, transaction details).
Protocol Support: Supports Modbus or custom protocols for seamless integration with existing billing infrastructure.
Data Flow: The controller sends parking events (e.g., vehicle entry/exit) to the billing system and receives commands for access control or payment confirmation.
Advantages
Remote Debugging and Flexibility: Equipment vendors can use BLRAT to remotely adjust pulse parameters, monitor system status, and troubleshoot issues, reducing on-site maintenance costs.
Scalability: The modular ARMxy architecture, with configurable X and Y boards, supports customization for different parking system sizes or configurations.
Robust Input Handling: The X-DI board’s mixed voltage input capability ensures compatibility with various sensors, simplifying integration and upgrades.
OpenPLC Programmability: OpenPLC’s support for IEC 61131-3 standards (e.g., Ladder Logic, Structured Text) enables flexible and standardized programming, reducing development time.
High Reliability: The ARMxy controller, combined with industrial-grade I/O boards, ensures stable operation in harsh environments, with EMC/EMI compliance for electromagnetic robustness.
System Workflow
Initialization: ARMxy controller boots, initializes Y-pulse and X-DI boards, and establishes RS485 communication with the billing system.
Lift Operation:
User requests a parking layer via the billing system.
ARMxy sends AB-phase pulses via the Y-board to drive the servo motor.
X-DI board monitors leveling sensors to ensure accurate positioning.
Safety Monitoring: Continuous anti-fall signal checks prevent unsafe operations.
Billing Integration: Parking events are transmitted via RS485, and billing system responses (e.g., access granted) are processed.
Remote Maintenance: Vendors use BLRAT to monitor performance, adjust pulse parameters, or update OpenPLC logic remotely.
Technical Specifications
