Built around the RK3506 industrial-grade HMI platform, integrating touch UI, offline voice interaction, room-control protocols and edge AI — delivering a mass-producible smart HMI for guest rooms, access control and public areas. One hardware platform covers a three-step evolution: networked → entertainment-enabled → health-upgraded.
From a single guest-room control panel to building-wide access control and network aggregation — the same RK3506 platform scales to the need.
RK3506 + LVGL touch UI centrally controls lighting, HVAC, curtains, scene modes and check-out reminders.
Offline voice wake and control for localized service and room-control linkage across guest profiles.
Edge-side local recognition, with optional linkage to on-site / third-party identity databases — verification without cloud.
Guest-room entertainment and meeting casting hub, doubling as floor network and device-protocol gateway.
Music, voice assistant and info push improve the stay experience and repeat-booking rate.
Devices networked, OTA upgrades, operational data to cloud — supporting centralized management and energy optimization.
Hardware composition and interface capabilities of a typical hotel HMI terminal.
| Subsystem | Key spec / tech | Role |
|---|---|---|
| Main controller | RK3506 (3×Cortex-A7 + M0, industrial −40~85℃) | HMI rendering, protocol handling, edge inference |
| Display | MIPI DSI / RGB, up to 1280×1280, LVGL | Touch UI, status visualization |
| Voice | External audio codec + mic; offline voice wake / broadcast (optional Bestom M08D audio module) | Local voice control & service |
| Touch | Capacitive / resistive, multi-point | Panel operation |
| Room-control interface | Dual CAN / RS485 / UART / SPI | Connects RCU / room-control host / motors |
| Network | Dual GbE + WiFi + BLE / Zigbee gateway | Networking, meshing & mobile-device interconnect |
| Edge AI | Local face / behaviour recognition (with camera), body-temperature module (optional) | Access-control verification & contactless temperature |
| Power | ~2.4 W with screen | Low-power long-term online |
| Hotel design highlights | |
|---|---|
| Operating temperature | Industrial −40 ~ +85 ℃ |
| Long-term supply | Rockchip industrial line, long lifecycle |
| Real-time core | M0 co-processor handles real-time I/O |
| Graphics framework | LVGL, light and high-frame-rate |
| Protocol compatible | Modbus / CANopen / private room-control protocols adaptable |
| Voice privacy | Local processing, no cloud upload |
| Form factor | 86-box / wall / desktop terminal, flexible |
| Upgrade path | Hardware reserved, software OTA evolution |
Layering offline voice on top of the HMI lets guests "speak instead of touch". Voice and touch coexist as dual modes, not replacements.
Local keyword wake, no network round-trip — fast response and works offline.
For an international guest base, loadable recognition models cover common room-control intents.
Voice commands like "sleep / read / leave" directly drive lighting, HVAC and curtain scenes.
Voice for quick control, touch for fine settings — complementary experience.
Voice can be recognized locally; sensitive data never goes to cloud, hotel compliant.
Voice results are sent via CAN/RS485 to the RCU and electromechanical devices for closed-loop execution.
Hotel smartification follows a progressive path — networked → entertainment-enabled → health-upgraded — and the RK3506 platform reserves capacity for all three steps at once.
| Stage | Goal | RK3506 platform support |
|---|---|---|
| Step 1 · Networked | Device interconnection, centralized management, OTA | Dual Ethernet/WiFi/BLE + real-time core, stable integration |
| Step 2 · Entertainment-enabled | Voice assistant, music, casting | Voice codec + display + gateway capability |
| Step 3 · Health-upgraded | Contactless temperature, health interaction | Edge AI + body-temperature module (optional) reserved |
