Sanya resort enhances energy management, automation, and guest services with Beilai's BL330 controllers, achieving energy savings and carbon neutrality.
Case Details
A renowned international coastal resort in Sanya, China, featuring over 200 ocean-view rooms, a large swimming pool, a spa with natural hot springs, and distributed photovoltaic (PV) systems, sought to enhance guest experience, reduce operational costs, and achieve carbon neutrality. The resort adopted Beilai Technology’s ARMxy BL330 Series Industrial Controller to build an integrated smart hotel solution covering energy management, facility automation, and safety operations.
Key Challenges1.High Energy Waste: Manual control of HVAC and lighting led to excessive energy consumption in unoccupied rooms.
2.Dispersed Equipment Management: Outdoor facilities (e.g., pools, pump rooms) required frequent manual inspections.
3.Limited Guest Personalization: Traditional room controls failed to meet modern expectations for smart hospitality.
SolutionBeilai deployed BL330 Edge Computing Controllers + Customized I/O Modules to enable multi-scenario intelligence:
1. Smart Energy Management
Hardware Configuration:
BL332B Host (3 Ethernet ports + dual Y-slots) + Y31 Analog Input Module (current/voltage monitoring) + Y24 Relay Module (equipment control).
SOM335 Core Board (8GB eMMC + 1GB RAM) for high-performance data processing.
Implementation:Real-time energy data collection (guest rooms, pools, PV systems) via BLIoTLink software, integrated with the resort’s energy management platform.
Automated Policies: Dynamic HVAC adjustment based on occupancy; solar energy prioritized for high-load areas.
Results:25% annual energy savings, 30% higher PV utilization, and recognition as a "Hainan Green Hotel Pilot Project."
Facility Automation & Remote O&M
Hardware Configuration:
BL331B Host (dual Ethernet + dual Y-slots) + Y58 Temperature Module (pool/spring monitoring) + Y01 Digital I/O Module (pump control).
Implementation:Automatic pool heating activation when temperatures drop below thresholds; water leakage alarms via BLIO modules.
BLRAT Remote Tool enabled real-time equipment monitoring, reducing on-site inspections by 80%.
Enhanced Guest Experience
Hardware Configuration:
BL330W Host (WiFi module) + X23 Multi-function I/O Board (RS485/DI/DO) integrated with room control systems.
Implementation:
Guests used a mobile app to adjust lighting/curtains; systems auto-reset after check-out.
Edge Computing: BL330 stored guest preferences (e.g., temperature), restoring settings for repeat visits—boosting satisfaction rates by 40%.
Technical Highlights
Heterogeneous Multi-Core Processor:
Allwinner T113-i (Cortex-A7 + RISC-V + HiFi4 DSP) handled concurrent tasks (energy algorithms, video surveillance).
Industrial-Grade Reliability:
Passed -40°C to 85°C tests and IP30 rating, ideal for coastal high-salinity environments.
Modular Flexibility:
X/Y Series I/O Boards supported diverse sensors (e.g., PT100 for temperature, RS485 for smart meters).
