[0045] In the hotel industry, the guest room lighting environment is one of the important factors that affect the guest's stay experience. As people's requirements for quality of life increase, guests' demand for hotel room lighting is no longer limited to basic lighting functions, but they pay more attention to the comfort, flexibility and adaptability of lighting to different scenes. The traditional hotel room LED lighting control system has many shortcomings:

[0046] Lack of customization: Existing lighting control systems often only provide a limited number of preset lighting modes, such as "bright mode" and "sleep mode", and cannot provide personalized lighting color and scene settings based on the unique needs and preferences of each guest. For example, different guests have different requirements for light brightness and color temperature when reading, and traditional systems are difficult to meet these diverse needs.

[0047] Inflexible scene switching: In actual use, guests may need to frequently switch lighting effects between different activity scenes, such as switching from a relaxing movie-watching scene to a bright business office scene. The scene switching operation of traditional lighting control systems is complex and slow to respond, which cannot quickly and accurately meet the immediate needs of guests and affects the guest's experience.

[0048] Energy management issues: With a large number of hotel rooms, lighting energy consumption is an important part of hotel operating costs. Traditional lighting control systems lack effective energy consumption monitoring and intelligent energy-saving strategies, and are unable to automatically adjust light brightness and switch status according to the actual usage of the guest rooms, resulting in serious energy waste.

[0049] Difficult equipment maintenance: There are many lighting devices in hotel guest rooms and they are widely distributed. Traditional control systems cannot monitor the operating status of the equipment in real time. When equipment fails, troubleshooting and repair work is time-consuming and laborious, affecting the normal operation of the hotel and the guests' stay experience.

[0050] In order to solve the technical problems of the above-mentioned traditional lighting systems, such as lack of personalized customization, inflexible scene switching, inability to achieve intelligent energy consumption management and convenient equipment maintenance, and high operating costs.

[0051] As an emerging technology, digital twin technology can reflect the status and behavior of physical entities in real time and realize precise control and optimized management of physical entities by building digital models corresponding to physical entities in virtual space.

[0064] Corresponding to the above-disclosed hotel room lighting control system based on digital twin, the embodiment of the present invention also discloses a hotel room lighting control method based on digital twin. The following describes in detail a hotel room lighting control method based on digital twin disclosed in the embodiment of the present invention in combination with the above-described hotel room lighting control system based on digital twin.

[0065] refer to Figure 2 The present invention discloses a hotel room lighting control method based on digital twins, which is applied to a digital twin model, and includes: S1, obtaining physical parameters, electrical characteristics and installation positions of all LED lights in the hotel rooms, building a digital twin model and updating the model status in real time.

[0066] Install hardware devices such as LED lights, sensors (light sensors, human infrared sensors, sound sensors, etc.), smart control panels, and central control units in hotel rooms. Ensure that LED lights support PWM dimming technology to achieve precise brightness and color temperature adjustment. Distribute sensors reasonably in various areas of the guest rooms to accurately collect environmental data and personnel activity information. At the same time, connect all hardware devices to the central control unit through wired or wireless communication to build a stable and reliable communication network.

[0067] A digital twin model is built for each LED lamp in the hotel guest room and the entire lighting system. By collecting and analyzing the physical parameters (such as power, color temperature, brightness adjustment range, etc.), electrical characteristics, and installation location of the LED lamp, a digital model that corresponds to the actual LED lamp is created in the virtual space. At the same time, a topological structure model of the entire guest room lighting system is constructed to simulate the signal transmission, control logic, and interaction relationship of the lighting system with other devices. For example, using 3D modeling technology, the layout of the lamps in the guest room is presented in an intuitive form, and the status information of each lamp is updated in real time in the model.

[0068] Various sensors are deployed in the guest rooms, including light sensors, human infrared sensors, sound sensors, etc. The light sensors collect real-time data on ambient light intensity in the guest rooms, the human infrared sensors detect the activity status and location information of people in the guest rooms, and the sound sensors capture sound signals such as voice commands issued by guests. These sensors transmit the collected data to the central control unit of the system in real time, providing data support for intelligent control of lighting.

[0069] Using professional modeling software and tools, a digital twin model is created based on the actual layout of the guest rooms and the parameter information of the LED lights. During the model creation process, the physical properties, electrical characteristics, and installation location of each LED light are entered and mapped in detail to ensure a high degree of consistency between the digital twin model and the actual physical system. Initialize the model state, set the initial lighting scene and parameters, and prepare for the operation of the system.

[0070] S2. Continuously collect environmental data and personnel activity information in the guest room, combine the environmental data and personnel activity information with the digital twin model for analysis and decision-making, and generate lighting control instructions.

[0071] For example, when the human infrared sensor detects that a guest has entered the guest room, the system automatically adjusts the brightness, color temperature and color of the LED light according to the preset welcome scene mode to create a warm and comfortable welcome atmosphere; when the guest is reading in the guest room, the light sensor detects that the ambient light is insufficient, and the system automatically adjusts the light to a brightness and color temperature suitable for reading. At the same time, the module can also quickly and accurately perform corresponding lighting control operations according to the guest's voice commands, such as "brighten the lights" and "switch to sleep mode".

[0072] S3, the lighting control instruction adjusts the brightness and color temperature of the target LED lamp through PWM, so that the current state of the target LED lamp is modified to the set state.

[0073] According to the control instructions generated by the intelligent control decision module, the LED lights in the guest rooms are driven and controlled. Through PWM (pulse width modulation) dimming technology, the brightness and color temperature of the LED lights are accurately adjusted to achieve a smooth, flicker-free light color adjustment effect. At the same time, it supports independent control of different areas and types of LED lights to meet the diverse lighting needs of guests in different scenarios. For example, different light brightness and color temperature can be set in the rest area and work area of ​​the guest room to meet different activity needs.

[0074] S4. The digital twin model is used to monitor the energy consumption data of each LED lamp in real time, and energy-saving strategies are formulated in combination with the usage of the guest rooms and the behavioral habits of the guests, and the lighting operation status and energy consumption data of the guest rooms are sent to the administrator terminal.

[0075] The administrator terminal and user terminal provide a convenient interactive interface for hotel managers and guests. Hotel managers can use this module to remotely monitor and manage the guest room lighting system, view the operating status of each guest room's lighting, energy consumption data and other information in real time, and perform unified parameter settings and scene configurations. Guests can independently select and customize personalized lighting scenes, such as romantic dating scenes, relaxing and leisure scenes, etc., through the control panel in the guest room, mobile phone APP, etc., and can also adjust the brightness, color temperature and other parameters of the light in real time to achieve autonomous control of the light.

[0076] Furthermore, the physical parameters, electrical characteristics and installation locations of all LED lights in the hotel guest rooms are obtained, including: the physical parameters include power, color temperature, and brightness adjustment range.

[0077] Furthermore, a digital twin model is constructed and the model status is updated in real time, including: analyzing the physical parameters, electrical characteristics and installation locations, and creating a digital model that corresponds one to one with the LED lamp in the virtual space; topologically analyzing the lighting system of the guest room, constructing a topological structure model, and simulating the signal transmission, control logic and interaction relationship of the lighting system; combining the digital model and the topological structure model to construct a digital twin model.

[0078] Furthermore, constructing a digital twin model and updating the model status in real time also includes: initializing the digital twin model and setting initial lighting scenes and parameters.

[0079] After the system is installed, comprehensive debugging is carried out. Check whether the connection of each hardware device is normal, whether the sensor data collection is accurate, and whether the synchronization between the digital twin model and the actual system is timely. By simulating different scenes and user operations, the algorithm of the intelligent control decision module is optimized and adjusted to ensure that the system can accurately and quickly respond to various control instructions and achieve ideal lighting color adjustment and scene switching effects.

[0080] Furthermore, environmental data and personnel activity information in the guest room are continuously collected, including: deploying light sensors, human infrared sensors and sound sensors in the room.

[0081] Among them, the light sensor is used to collect the ambient light intensity data in the guest room in real time, the human infrared sensor is used to detect the activity status and location information of people in the guest room, and the sound sensor is used to capture the voice command sound signal issued by the guest.

[0082] Furthermore, the lighting control instruction adjusts the brightness and color temperature of the target LED lamp through PWM to modify the current state of the target LED lamp to a set state, and also includes: independently controlling different areas and different types of LED lamps in the guest room.

[0083] Furthermore, the method also includes: using the digital twin model to detect in real time whether an abnormality occurs in a device managed by the digital twin model; when an abnormality is detected, an alarm is issued and the fault location and cause are quickly located.

[0084] In the embodiment of the present invention, it is also necessary to provide system usage training for hotel managers and guests.

Provide guests with concise and easy-to-understand operation guides to guide guests on how to perform personalized lighting control and scene switching through control panels, mobile phone APPs, etc., so that guests can easily enjoy the convenience and comfort brought by smart lighting.

[0085] Establish a regular system maintenance mechanism to inspect and maintain hardware equipment to ensure the normal operation of the equipment. At the same time, according to the hotel's development needs and guest feedback, timely upgrade and optimize the system's software, continuously improve the digital twin model, update the intelligent control algorithm, improve the system's performance and functions, and provide better services for the hotel and guests.
