Intelligent Stereo Garage Lifting Control New Solution: BL450 Embedded Computer Enables Efficient, Safe, and Remote Management

Application Scenario & Requirements Scenario: 12-level vertical lift parking system

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
• OpenPLC programming allows on-the-fly logic adjustments without on-site operation

Technical Advantages

✅ High Precision: 100kHz pulse output + real-time feedback ensures accurate parking

✅ Mixed Signal Compatibility: DI board supports 12–24V wide-voltage input, adaptable to diverse sensors

✅ Industrial-grade Reliability: Operates from -40°C to +85°C, EMC Level 3 certified, strong interference resistance

✅ Remote Maintenance: Combined with BLIoTLink protocol conversion and BLRAT for fault alerts and cloud-based management

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

Solution is adaptable to AGVs, production lines, and other industrial automation scenarios under Industry 4.0
