Abstract
Description
Technical Field
[0001] This invention relates to the field of smart doorplate technology, and in particular to a programmable projection smart doorplate and control system. Background Technology
[0002] Traditional hotel door signs are increasingly showing their limitations and incompatibility with the times under the dual impact of technological iteration and upgrading consumer demands. The core positioning of traditional door signs remains "information display" rather than "service entry point," with extremely narrow functional boundaries, failing to meet the current hotel's demand for "scenario-based services." The products can only achieve basic "room number display + status switching" (such as "Do Not Disturb" and "Please Clean Immediately"), and the functional modules are fixed at the factory. They cannot be flexibly upgraded according to the hotel's operational needs (such as creating a festive atmosphere, exclusive reminders for members, and push notifications for value-added services). 2. The door sign status relies entirely on guests manually pressing buttons, and the hotel can only "passively receive signals" and cannot actively reach guests (for example, after a guest presses "Do Not Disturb" in the room, cleaning staff need to repeatedly check the door sign to confirm the status). If guests forget to turn off the status, they may miss services such as food delivery and maintenance, creating a service gap. Furthermore, traditional door sign products mostly rely on wired networks and mains power, requiring wall drilling and wiring during installation, resulting in high installation costs. In summary, the core problem with existing traditional doorplates is that their design logic remains at a rudimentary stage, merely displaying room numbers and service requests, failing to keep up with the hotel industry's development trends of personalization, data-driven operational management, and the Internet of Things (IoT) of equipment ecosystems. For today's hotels, doorplates are no longer just "information tools," but should be "key display points for guest room services, data collection nodes for operational data, and connection points for smart ecosystems." This is precisely the most fundamental inadequacy of traditional products. In view of this, this application proposes a programmable projection smart doorplate and control system. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a programmable projection smart doorplate and control system.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A programmable projection smart doorplate and control system includes a guest control platform host, a smart panel, a gateway, an SOS panel, an air monitoring box, and a smart door lock. The guest control platform has a built-in guest control system, and the guest control platform host, smart panel, SOS panel, air monitoring box, and smart door lock are all communicatively connected to the gateway.
[0005] Preferably, the guest control system is used to comprehensively manage and monitor the status of room equipment, room environment information and energy consumption management under different room conditions, and to implement batch management and control of room equipment.
[0006] Preferably, the smart panel is used to display, but is not limited to, room number, room air quality information, and date, to provide personalized services and promotions for the hotel, and to provide an entry point for collecting relevant room information. The smart panel has a screen size of 5.6 inches. The smart panel integrates a projection function. When the SOS button is pressed in the room, the smart panel will automatically notify the hotel front desk and display an emergency service notification in full screen. The projected room number will be temporarily changed to SOS so that nearby people can provide timely assistance. The SOS panel in the room can be unlocked with a key to restore the SOS of the projected room number to normal. The smart panel integrates a dynamic service information push function, which is used to temporarily push information including member welcome messages (such as "Welcome Mr. / Ms. XX"), hotel activities (such as "The gym is open until 22:00 today"), and personalized content for late-night food delivery.
[0007] Preferably, the guest control platform host, smart panel, SOS panel, air monitoring box and smart door lock form an independent networking system. The gateway is used to connect, translate and manage the sub-devices in the independent networking system, ensure compatibility between different devices, protocols and networks, and provide orderly data flow to ensure the safe and reliable operation of the independent networking system.
[0008] Preferably, the SOS panel has an emergency button for providing a distress call function. When a user faces a threat to personal safety, encounters an emergency, or discovers a major safety hazard in the surrounding area, pressing the emergency distress button will immediately send an alarm message to the relevant property management department and personnel, quickly reporting the emergency and requesting assistance.
[0009] Preferably, the guest room control platform host is the core of the guest room equipment control, supporting precise individual control of room lights, curtains and air conditioning; and has a scene-based control function to realize one-click group opening and closing of multiple devices in "check-in mode" or "check-out mode".
[0010] Preferably, the air monitoring box is installed in the guest room and is responsible for monitoring the air quality in the guest room in real time. It also synchronously uploads the collected detection data to the gateway and smart panel to provide users with an intuitive reference of the environmental status. The air quality includes, but is not limited to, PM2.5, formaldehyde, temperature and humidity, and CO2 levels.
[0011] Preferably, the smart door lock is used to control the opening and closing of the guest room door, and at the same time collects and synchronizes the opening and closing status of the door to the guest control system in real time. The opening and closing status includes closed, unlocked, and deadbolted.
[0012] Preferably, the smart panel integrates intelligent interaction functions, the specific logic of which is as follows: S101: Visitor and Access Control Closed-Loop Management: S1011: Integrated doorbell function: When a visitor rings the doorbell, the smart panel screen displays a synchronized ringtone animation, replacing the traditional physical doorbell; S1012: Visitor Confirmation Interaction: After the guest confirms the visitor's identity via mobile APP or the room control screen, the door can be opened with one click; S1013: One-click unlocking: Supports guests to unlock directly via facial recognition or password verification through the smart panel's door display screen, or to achieve seamless door opening by linking with mobile phone via Bluetooth / WiFi, replacing traditional room cards and reducing the risk of loss; S201: Guest interaction: After submitting "Please clean immediately", the door display screen of the smart panel can display "and promptly notify the housekeeping department" in real time, solving the pain points of traditional hotels that require phone calls and "no feedback after operation". S301: Hotel-side interaction: Cleaning staff can directly determine the timing of service by checking the status of the door display screen (such as "Do Not Disturb" + "No One Inside"), without having to knock on the door repeatedly to confirm. S401: Data-Driven Operations: Its specific logic is as follows: S4011: Automatically collects service response data (such as the average processing time for "Please clean immediately") and guest behavior preferences (such as the high-frequency periods of "Do Not Disturb") to provide a basis for hotels to optimize staff scheduling and adjust service processes; S4012: Environmental data linkage: When indoor PM2.5 exceeds the standard, a prompt "Do you need to turn on the air purifier?" can be automatically pushed to the door display or guest room equipment to improve the perception of health services; S4013: Seamless integration with hotel PMS / CRM systems: Automatically synchronizes guest information (such as membership level) upon check-in and immediately resets the smart panel status upon check-out, reducing manual operation; S4014: Supports OTA remote upgrades: New features (such as holiday-themed skins and QR code call services) can be pushed online without replacing hardware, extending the device's lifespan; S4015: Multiple connection methods: compatible with WiFi / Bluetooth, adaptable to the network environment of new and old hotels, reducing the difficulty of transformation and cabling costs.
[0013] Compared with existing technologies, the beneficial effects of this invention are: The smart doorplate provided by this invention completely replaces traditional doorplates, doorbells, peepholes, and "Do Not Disturb" signs, achieving "one-screen integration" and providing guests with great convenience and security. It enables cardless entry, visitor confirmation, environmental monitoring, and service calls through a single screen, allowing guests to enjoy a personalized smart experience. For hotels, it significantly reduces costs and increases efficiency, minimizing the procurement, wiring, and maintenance costs of multiple devices. It can automatically synchronize information with the PMS system and collect service data to optimize scheduling and service processes. Furthermore, its technologically advanced image becomes a core competitive advantage for attracting customers, increasing room rates, and enhancing reputation. It is a key entry point for achieving digital upgrades in hotels. Customized interfaces and intelligent functions also help enhance the brand's technological appeal, achieving the dual value of cost reduction, efficiency improvement, and enhanced experience.

[0017] In this embodiment, the specific installation and operation logic steps of the programmable projection smart doorplate and control system are as follows: S1: Door display installation and network configuration: Hardware installation: Install the smart panel at the reserved wiring point of the door display (or the original door display wiring port). Fix the smart panel in place according to the design requirements and the actual site conditions. Network configuration: If a network cable has been pre-installed on site, simply plug in the network cable and set a fixed IP address in the smart panel's door display system to complete the network configuration; If no network cable is pre-installed, a wireless network can be added through the smart panel's door display system settings interface to achieve network configuration; S2: Door display information configuration: Room number synchronization: After the smart panel and the guest control platform host are successfully networked, the guest control platform host will automatically send the room number information to the door display. After the room number is synchronized, the smart panel will automatically project the room number onto the ground. Customizable information settings: The smart panel can be customized to display information such as time, indoor air parameters, and background image via the web management interface; the guest room control system will send the air quality data of the corresponding rooms collected by the air detection box to the smart panel via the network, and the smart panel will display information such as room number, date, and air quality; S3: Door display and door lock association: Once the smart panel and the guest control platform host are successfully networked, the guest control platform host automatically identifies and associates the smart panel and smart lock that are on the same IoT network (such as Bluetooth Mesh, RS485, etc.), and associates the smart panel and smart lock. When the door is opened through the smart panel, the door opening message is sent to both the smart lock and the guest control platform host at the same time. When the smart lock receives the unlocking message, the door lock turns and sends a lock opening message back to the guest control platform host. Seamless check-in: After check-in / information is entered at the front desk (depending on the property type, such as hotel, apartment, or residence), the guest control system sends the user information to the smart panel via the cloud / local network. Users can then walk to the designated door and open it by facial recognition or password. Inside the room, they can set the room service lights by pressing buttons or using voice commands, and can also open the door from inside using buttons and mini-programs.
