Technical Field

[0001] The present application relates to the technical field of intelligent hotel environment control, and in particular to a hotel room environment control system based on digital twins. Background Art

[0002] The application of intelligent technology in the hotel industry is becoming more and more widespread, which has become an important force driving the transformation of the hotel industry. By introducing intelligent systems, hotels can achieve intelligent control and management of various equipment in guest rooms, thereby providing a more convenient, comfortable and personalized accommodation experience.

[0003] In the modern hotel industry, the environment of the guest rooms mostly depends on the customers to adjust themselves through the environmental actuator control switch, that is, the temperature, humidity and light adjustment are adjusted by the customers themselves through the air conditioning adjustment switch, humidifier adjustment switch and lighting adjustment switch. For example, the publication number CN102880160A "Intelligent Hotel Control System" sets a lighting control touch panel, an air conditioner, and an environmental control touch panel for a humidifier, and performs autonomous environmental adjustment. This method is not highly targeted and relies on no customer self-adjustment, and cannot provide residents with personalized biochemical environmental adjustment. Summary of the invention

[0004] Based on this, in response to the above technical problems, a hotel room environment control system based on digital twins is provided to provide hotel residents with a more personalized and biochemical environmental adjustment experience.

[0007] Data acquisition module: used to receive real-time environmental data collected by sensors installed in guest rooms, the environmental data including: temperature, humidity and lighting;

[0008] Analysis module: used for inputting the received user's environmental expectation data into a pre-built prediction environment model to output prediction environment data;

[0009] A calculation module: used for calculating the adjustment data of the environment adjustment actuator according to the real-time environment data and the predicted environment data; the environment adjustment actuator includes a light adjustment component, a humidifier adjustment component and a temperature adjustment component;

[0010] Effect display module: used to update the lighting actuator adjustment data and the real-time lighting data into the three-dimensional model of the guest room, and output the three-dimensional model after the data is updated;

[0011] Control module: used for controlling the action of the environment regulating actuator according to the calculated regulating data of the environment regulating actuator.

[0012] In the above solution, optionally, the system includes: an instruction receiving module: used to receive the adjustment data of the environment adjustment actuator sent by the remote terminal;

[0013] The control module is further configured to control the action of the environment regulating actuator according to the regulation data of the environment regulating actuator sent by the remote terminal when the regulation data of the environment regulating actuator is received from the remote terminal.

[0014] In the above solution, optionally, the system further comprises: a resident sensing module: used to detect whether there is someone living in the guest room;

[0015] The control module is also used to control the environment adjustment actuator to not operate when receiving information output by the occupancy sensing module indicating that no one is in the guest room.

[0016] In the above solution, further optionally, the occupancy sensing module includes infrared detectors arranged at multiple positions in the room, and a processor;

[0017] The processor determines whether there is someone living in the guest room based on the data from the infrared detector.

[0018] In the above solution, optionally, the predicted environment model is constructed by using a large amount of user environment expectation data and corresponding environment data actually used by the users.

[0019] In the above solution, optionally, the sensor includes: a temperature sensor, a humidity sensor, a color temperature sensor, and a brightness sensor.

[0022] This application has at least the following beneficial effects:

[0023] This application obtains the user's environmental expectations when the resident moves in, and then outputs the predicted accurate environmental data expected by the user through the pre-built environmental prediction model. Since the environmental expectation data input by the user is not the same as the satisfactory environmental data of the actual user living in the room, a prediction model is built to predict the accurate expected environmental data of the user based on the environmental expectation data of the user. Then, the adjustment data of the environmental actuator is calculated based on the collected environmental data of the guest room, thereby taking into account the different environmental data of the guest room itself at different times, so as to adjust the environment to the accurate expected data of the user through the data of the environmental adjustment actuator. In this way, the adjustment and control of the personalized biochemical environment is realized, which does not rely on the customer's self-adjustment and improves the user's satisfaction. At the same time, by constructing a three-dimensional model, the lighting actuator adjustment data and the real-time lighting data are updated to the three-dimensional model of the guest room, and the three-dimensional model after the data update is output, the user can see in advance the actual lighting effect generated based on the lighting expectations input by himself and combined with the existing lighting, thereby increasing the user experience.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] In one embodiment, Figure 1 As shown, a hotel room environment control system based on digital twin is provided, and the system includes:

[0027] Model building module: used to build a three-dimensional model of the hotel room based on the CAD structural drawings of the hotel room, as well as the execution data of the lighting actuator and the corresponding display data;

[0028] Data acquisition module: used to receive real-time environmental data collected by sensors installed in guest rooms, the environmental data including: temperature, humidity and lighting;
