Core Requirements:
High-precision motor control for smooth lifting operations
Real-time detection of level alignment and anti-fall signals for safety
Seamless interaction with payment systems for intelligent management
Challenges:
Traditional PLC-based systems are complex to debug, struggle with height variations, and lack remote management capabilities.
Hardware Configuration
1.Main Controller:
BL450 – Industrial-grade RK3588J processor with 4x A76 + 4x A55 cores
2. Motion Control:
Y95 Board:
4 PWM outputs (1 channel at 100kHz for servo motor positioning)
3 low-speed pulse counters (for encoder feedback verification)
NPN-compatible interfaces for mainstream servo drivers
3. Safety Monitoring:
X13 Board:
2 DI channels: capture level sensor and anti-fall switch signals (supports 12–24V input)
2 DO channels: control emergency relays and status indicators
4. Communication:
Built-in RS485 for direct connection to payment systems
Implementation
Closed-loop Control
Y95 board sends AB phase pulses to control servo motors, adjusting speed and lift position
X13 board collects level signals in real-time, with algorithmic calibration to ensure millimeter-level accuracy
Remote Debugging
Using the BLRAT remote tool, integrators can fine-tune pulse parameters (frequency, acceleration curves) to match varying lift heights
Customer Value
Cost Reduction: Integrated design eliminates the need for separate PLC + gateway, reducing hardware costs
Efficiency Boost: 30% increase in servo motor response speed, significantly improving parking throughput
Enhanced Safety: Hardware watchdog and EFT-protected design prevent unexpected shutdowns
Future-Proof: Supports 5G/WiFi modules, ready for smart booking and license plate recognition systems
