• Implementation:
  • Y-series I/O boards (e.g., Y51/Y52) support PT100/PT1000 RTD measurements for high-precision temperature and humidity monitoring.
  • Data is transmitted to an Energy Management System (EMS) via Ethernet or 4G.
  • BLRAT tool enables remote access for maintenance personnel to monitor environmental status in real time.
• Advantages: Wide voltage input (9-36VDC) and overcurrent protection ensure stability in complex power environments.

(4) Automated Equipment Control

  • X-series I/O boards (e.g., X23/X24) provide DI/DO interfaces for switching control and status detection.
  • Supports Qt-5.15.10 for developing Human-Machine Interfaces (HMI), output via HDMI to touchscreens for operator monitoring.
  • Docker containers deploy control programs, improving system maintainability.
• Advantages: Modular I/O design enables quick adaptation to different devices, and the Linux system supports complex control logic.

Advantages of Smart Warehousing Solutions

Using the BL370 series for smart warehousing solutions offers the following benefits:

• Modular Design: SOM boards and I/O board combinations meet the needs of different warehouse scales and equipment, reducing customization costs.
• High Reliability: Passes EMC tests (ESD, EFT, Surge, etc.) and environmental tests (-40 to 85°C, vibration, drop), ensuring long-term stable operation.
• Rapid Deployment: Pre-installed BLloTLink and BLRAT software support mainstream protocols and cloud platforms, shortening system integration time.
• Development Support: Rich development examples (Node-RED, Qt, Docker, NPU, etc.) reduce secondary development complexity, ideal for rapid prototyping and customization.

Implementation Recommendations

• Hardware Selection:
  • For scenarios requiring high-performance computing (e.g., vision processing), choose SOM372 (32GB eMMC, 4GB LPDDR4X, RK3562J).
  • For multi-device connectivity, select BL372B (3 Ethernet ports, 2 Y-board slots).
  • For cold storage applications, choose SOM370/371/372, supporting -40 to 85°C.
• Software Configuration:
