The details in this specification can also be applied based on different viewpoints, and various modifications or changes can be made without departing from the overall design concept of the invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. The following exemplary embodiments of the present invention can be implemented in many different forms and should not be construed as being limited only to the specific embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present invention complete and thorough, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0017] Embodiment 1

[0018] This embodiment provides a robot for providing auxiliary lighting for a car, which has an illuminance sensor, a control device, and a lighting device. The illuminance sensor is, for example, a photoresistor sensor, a photodiode sensor, a photocoupler sensor, etc.

[0019] When the robot is in the car, the control device controls the illuminance sensor to detect the illuminance in the car; when the illuminance in the car is less than the preset illuminance threshold, the control device controls the lighting device to turn on to provide auxiliary lighting for the car.

[0020] The lighting device has at least two preset lighting brightness levels. The control device selects the lighting brightness according to the difference between the detected illuminance in the car and the preset illuminance threshold, so that the actual illuminance in the car tracks the preset illuminance threshold, that is, a closed-loop control is formed.

[0021] Embodiment 2

[0022] Based on Embodiment 1, the robot in this embodiment further has a communication device; the communication device is communicatively connected to the elevator control system, such as in wireless communication manners like WiFi, Bluetooth, Zigbee, LoRa, 4G, NB-loT, etc.

[0023] The robot classifies the perception results into three types according to the lighting level: sufficient lighting, insufficient lighting, and lighting failure. When there is sufficient lighting, the robot does not need to activate the lighting device.

[0024] When the illuminance in the car is less than the preset illuminance threshold, indicating that there is a lighting failure in the car, in addition to providing auxiliary lighting for the car using its own lighting device, the robot also sends a warning message indicating the lighting failure in the car to the elevator.

[0025] Embodiment 3

[0026] Based on Embodiment 1 or 2, the robot in this embodiment further has a human body sensing device. When the robot is in the car, the control device uses the human body sensing device to detect whether there are passengers in the car; when the illuminance in the car is less than the preset illuminance threshold and there are passengers in the car, the control device controls the lighting device to turn on to provide auxiliary lighting for the car.

[0027] Or obtain the information on whether there are passengers in the car through communication with the elevator control system; when the illuminance in the car is less than the preset illuminance threshold and there are passengers in the car, the control device controls the lighting device to turn on to provide auxiliary lighting for the car.

[0028] Embodiment 4

[0029] Based on Embodiment 1, the robot in this embodiment further has a communication device; the communication device is communicatively connected to the elevator control system to receive the auxiliary lighting demand information sent by the elevator control system; the control device adjusts the brightness or color temperature of the lighting device according to the auxiliary lighting demand information.

[0030] Alternatively, the communication device is communicatively connected to the user interaction system to receive the auxiliary lighting demand information sent by the user interaction system; the control device adjusts the brightness or color temperature of the lighting device according to the auxiliary lighting demand information. The auxiliary lighting demand information includes one or more of brightness, color temperature, time, or weather.

[0031] Passengers or customers can customize the light color and appropriate light intensity through the robot. After receiving the data analysis results from the elevator system, including but not limited to factors such as weather conditions and time periods, the light intensity and color are intelligently adjusted according to the analysis results to improve the car environment.

[0032] Passengers or customers can customize the light color through the robot (such as white, warm yellow, etc.), and can customize the display of different light colors and intensities at different time periods through the robot. For example, during the day (the set time can be from 8:00 to 17:00), the light color is milky white, and at night (the set time can be from 18:00 to 8:00), the light color is warm yellow. The light intensity at different time periods is controlled by a timeline. Passengers or customers can customize the robot to set the light intensity to low when the weather is sunny, medium when the weather is cloudy, and high when the weather is rainy through the robot.

[0033] Compared with the prior art, this embodiment improves the riding experience, enabling passengers to enjoy suitable lighting conditions at any time period; at the same time, it automatically adjusts the brightness and color temperature according to environmental changes and user preferences; and enhances safety, avoiding potential safety hazards caused by unclear vision.

[0034] Embodiment 5

[0035] This embodiment provides an elevator control method. When the robot determines that there are passengers in the car and the car lighting is insufficient or there is a lighting failure, it sends a lighting failure warning message and a supporting request to the elevator control system; the elevator control system controls the elevator to give priority to stopping at the destination floor of the passengers in the car until there are no passengers in the car; the elevator control system controls the elevator to stop at the destination floor of the robot, and the robot leaves the car. Compared with the prior art, this example improves the riding experience, enabling passengers to enjoy suitable lighting conditions at any time period; and enhances safety, avoiding potential safety hazards caused by unclear vision.
