Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to an adaptive dimming system, a ship, and a control method. Background Technology

[0002] Cabins are a crucial part of the design of all types of passenger ships, and lighting is a significant factor affecting the passenger travel experience. However, some large passenger ships still use conventional single-color temperature lighting fixtures in their passenger cabins, and conventional push-button switches are still used to turn the cabin lighting on and off. This outdated dimming method and monotonous light source make it difficult to meet the personalized lighting needs of different customer groups, and the unchanging lighting style is hard to keep up with the development needs of the emerging cruise market.

[0003] To provide passengers with a better accommodation experience during cruise voyages and to promote the further development of the cruise market, there is an urgent need for a new dimming method and system that can automatically meet the different lighting needs of different customer groups, enabling cabin lighting to achieve human-centered adaptive dimming.

[0004] Currently, the outdated lighting design in passenger ship cabins suffers from the main problem of simple on / off controls, which prevent passengers from selecting their preferred indoor lighting environment, resulting in a poor passenger experience. To improve this situation, some passenger ships have adopted independent adjustable lighting for each cabin. However, in reality, some passengers are unsure how to find the most suitable optical configuration (color temperature / brightness / color combination) for themselves. Without networked analysis of group dimming data as a reference, the isolated random dimming operation sometimes fails to allow the dimming fixtures to achieve their optimal effect. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, the present invention provides an adaptive dimming system, a ship and a control method. Based on dimming network technology and dimmable lamps, the system collects a large number of different customer groups’ different cabin dimming needs through a network platform in each voyage cycle, and statistically analyzes and determines the optimal optical requirement combination for different customer groups. This process is iterated and optimized repeatedly to finally form a dimming logic that is most suitable for the needs of various passengers.

[0006] This invention provides an adaptive dimming system for use on passenger ships, the adaptive dimming system comprising:

Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0048] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0049] This invention provides an adaptive dimming system for use on passenger ships, such as... Figures 1 to 5 As shown, the adaptive dimming system includes: a cabin lighting intelligent analysis and control unit 1, a ship network communication server 2, a passenger information registration subsystem 4, and a communication service subsystem, specifically:

[0050] The passenger information registration subsystem 4 is used to register passengers' basic information and their corresponding cabin information. At the same time, it sends the passengers' basic information and their corresponding cabin information to the ship's network communication server 2. While being used for routine ship operation management, it also provides necessary data support for the dimming optimization analysis of the cabin lighting intelligent analysis main control unit 1. In addition, the passenger information registration subsystem 4 is also used to provide voyage start instructions (passenger registration) and voyage end instructions (passenger check-out) for the dimming control logic.

[0051] The communication service subsystem is used to receive dimming commands and collect dimming status information of passengers in their living quarters. In this embodiment, the communication service subsystem may include a network switch 3 and a communication conversion control module 5 installed in each living quarter. Specifically, each living quarter communication conversion control module 5 is assigned a network communication IP address corresponding to the living quarter where the communication conversion control module 5 is located, so as to accurately upload dimming status information and accurately receive dimming commands. The network switch 3 includes multiple customer network ports that are respectively connected to the communication conversion control modules 5 in the living quarters of each deck, so as to collect dimming status information of each passenger, receive dimming commands sent by the cabin lighting intelligent analysis main control unit 1, and accurately send the dimming commands to the corresponding living quarters according to the communication addresses.

[0052] The ship network communication server 2 is used to acquire and store the basic information of passengers registered through the passenger information registration subsystem 4, as well as the dimming status information collected in real time through the communication service subsystem. The dimming status information may include the status information of the dimming lamp 7 after the passenger adjusts the dimming lamp 7 manually. After each voyage of the passenger ship, the above-mentioned basic information of passengers and dimming status information will be shared with the cabin lighting intelligent analysis main control unit 1.

[0053] The cabin lighting intelligent analysis and control unit 1 is used to perform big data grouping and / or classification statistical analysis on the dimming status information and basic information of all passengers in each voyage cycle obtained by the ship network communication server 2, to obtain the optimal dimming parameter combination, so as to issue the latest optimized dimming instructions to all types of passenger accommodation cabins on the ship at the start of a new voyage.

[0054] In some embodiments of the present invention, the cabin lighting intelligent analysis main control unit 1 is used to perform big data grouping and / or classification statistical analysis to obtain the optimal dimming parameter combination, so as to issue the latest optimized dimming instructions to all types of passenger accommodation cabins on the ship at the start of the next voyage. Specifically, at the start of a new voyage, based on the basic information of passenger registration and the current best dimming logic setting, corresponding dimming instructions are generated for each passenger's accommodation cabin according to the customer group.

[0055] Scientific research has shown that different age groups or customer groups have different needs for comfortable lighting, and the light requirements also vary at different times of the day. Therefore, in this embodiment, the customer groups can be divided into at least youth groups, middle-aged groups, elderly groups, and parent-child groups. At the same time, the dimming parameter combination can include at least color temperature parameters, brightness parameters, color parameters, and time period information. That is, based on the age of the passengers (corresponding to different age groups), whether they are parent-child groups, etc., the corresponding dimming light fixtures 7 control commands can be pre-configured for the cabins corresponding to the passengers staying on this flight, based on the data obtained from analyzing the existing dimming status information and the passengers' basic information. This allows for the optimal dimming light fixture 7 lighting mode to be directly formulated for the corresponding groups of passengers, providing the most comfortable and meeting their needs, thereby improving the passenger experience.

[0056] In addition, the cabin lighting intelligent analysis main control unit 1 is also used to: after the current voyage ends, combine the basic information of passengers and the dimming status information of passengers in their living quarters during the current voyage, as well as the basic information of passengers and the dimming status information of passengers in their living quarters during previous voyages, to perform big data grouping and / or classification statistical analysis, generate new dimming control parameter combinations, so as to issue the latest optimized dimming instructions to all types of passenger living quarters on the ship at the start of the next voyage.

[0057] In some embodiments of the present invention, the adaptive dimming system further includes: an uninterruptible power supply 8 and an in-cabin dimming panel 6 equipped in each living compartment. Specifically, the in-cabin dimming panel 6 equipped in each living compartment serves as a human-machine interface for recognizing and converting user dimming operations. In manual mode, it recognizes specific dimming commands input by passengers, converts them into electrical signals, and sends them to the communication conversion control module 5. In automatic mode, it activates the communication conversion control module 5 to receive dimming commands issued by the cabin lighting intelligent analysis main control unit 1. That is, the in-cabin dimming panel 6 can select between automatic and manual modes. After the automatic mode is triggered, the dimming command forwarding control unit 52 inside the communication conversion control module 5 prioritizes the cabin dimming mode. The cabin lighting intelligent analysis and control unit 1 issues dimming commands in a timely manner through the main network. After the manual mode is triggered, the dimming command forwarding control unit 52 suspends receiving dimming commands from the network and instead receives dimming commands for color temperature, color, and brightness from the cabin dimming panel 6. All dimming commands are ultimately forwarded by the dimming command forwarding control unit 52 to the dimming lamps 7 and the ship's network communication server 2 to realize the recording of manual dimming actions and dimming status information. The uninterruptible power supply 8 provides a continuous and reliable power supply for the cabin lighting intelligent analysis and control unit 1, the communication service subsystem, and the network switch 3. When the ship's main power grid fails, it can still ensure the normal operation of these main network control devices and ensure that important information is not lost.

[0058] In some embodiments of the present invention, the communication conversion control module 5 includes: a conversion module 51, a dimming command forwarding control unit 52, and a power interface unit 53. Specifically, the conversion module 51 can be a TCP / DALI conversion module 51, which, after receiving a network dimming command from the network switch 3, converts the dimming command of the network TCP / IP communication protocol into a dimming command of the DALI communication protocol and sends it. Specifically, the conversion module 51 transmits the DALI dimming command to the dimming command forwarding control unit 52. In this embodiment, the TCP / DALI conversion module 51 is used because the DALI dimming protocol is a professional and open dimming protocol that can be matched with many high-quality dimming devices. At the same time, the anti-interference characteristics of the DALI communication mode allow the control command and the power supply core wire to coexist on a single cable without interference (e.g., ...). Figure 2 The 4X1.5+E cable (2 cores for power supply, 2 cores for communication) improves the flexibility, economy, and reliability of the light distribution design.

[0059] The dimming command forwarding control unit 52 latches the received dimming command until it receives the next dimming command. Simultaneously, the dimming command forwarding control unit 52 receives the dimming command sent by the conversion module 51 and forwards the dimming command to the dimming lamp 7, so that the dimming lamp 7 dims based on the dimming command. The dimming command forwarding control unit 52 is used to receive manual dimming commands input by passengers through the cabin dimming control panel to dim the dimming lamp 7, allowing passengers to adjust the dimming lamp 7 in their living quarters according to their preferences. It also forwards the adjustment status information of the lamp after adjustment via the manual dimming command to the conversion module, and after conversion by the conversion module 51, sends it to the communication service subsystem. The light command forwarding control unit 52 feeds back the current manually dimmed state (e.g., color temperature 5000K, brightness 80%, ambient light blue) to the TCP / DALI conversion module 51, and finally transmits this information to the ship's network communication server 2 via the network switch 3 as data records for this voyage. The working logic of the dimming command forwarding control unit 52 is as follows: when the voyage departs, it receives and forwards the dimming command issued by the cabin lighting intelligent analysis main control unit 1 through the above network transmission path. During the voyage, when the cabin dimming panel 6 is manually operated on-site, it will read the dimming command of the cabin dimming panel 6 again and forward it to the downstream cabin dimming lamp 7 device (real-time manual dimming) and the upstream network communication device (for storing dimming status data).

[0060] The power interface unit 53 has voltage regulation and line overload protection functions. It is used to receive external AC power and supply power to the dimming control components and equipment in the living quarters via the dimming command forwarding control unit 52. As an example, the power interface unit 53 is an AC 230V power interface unit 53, which receives external AC 230V power and supplies power to various dimming control components and equipment in the living quarters via the dimming command forwarding control unit 52.

[0061] In some embodiments of the present invention, the adaptive dimming system further includes: dimming lamps 7 and colored ambient light strips 9 installed in each living compartment. The dimming lamps 7 are all digital dimming lighting devices with adjustable color temperature and brightness, used to receive dimming commands issued by the dimming command forwarding control unit 52 inside the communication conversion control module 5 in real time, and to perform dimming actions (i.e., light output changes) according to the latest dimming command. Old commands will be overwritten by new commands. The colored ambient light strips 9 installed in each living compartment include RGB LEDs that can adjust color and brightness, used to receive dimming commands, and to perform color changes according to the color dimming command in the received new dimming command for ambient lighting.

[0062] As can be seen from the above technical solution, since the IP address of the communication conversion control module 5 inside each living quarters corresponds one-to-one with the living quarters, the data collected by the ship's network communication server 2 through the network control bus is: room number + time + dimming status (color temperature, brightness, and color); while the ship's network communication server 2 can collect the correspondence between room number and passenger age (or group characteristics) through the passenger information registration subsystem 4. After receiving the above-mentioned data collected by the ship's network communication server 2, the cabin lighting intelligent analysis main control unit 1 uses database technology to classify the passenger cabin dimming requirements into big data according to Table 1, and simultaneously performs sample analysis.

[0063] Table 1: Classification of Passenger Cabin Dimming Demands Based on Big Data

[0064]

[0065] As shown in Table 1 above, the dimming data (color temperature, brightness, and hue) are categorized according to different passenger groups / time periods in the cabin lighting intelligent analysis main control unit 1. In the table, Value represents the average value of a single passenger sample selecting a dimming data (application value) within a certain time period, while Peak Range represents the most frequent selection of a dimming data (application value) by a certain passenger group within a certain time period, i.e., the peak value of the normal distribution of sample Value 1 to Value n. For example, the statistical analysis results of the normal distribution of a passenger group's demand for color temperature and brightness values ​​within a certain time period can be found in [reference needed]. Figure 3 As shown.

[0066] By extracting the range of values ​​on the horizontal axis corresponding to the peak values, the actual demand values ​​of a certain passenger group for various dimming parameters within a certain time period can be obtained. This yields the optimal preset values ​​for each dimming parameter for a certain passenger group within a specific time period of the day, "Peak Range (day1)". After the entire flight cycle is completed, the cabin lighting intelligent analysis main control unit 1 averages the data from "Peak Range (day1)" to "Peak Range (dayN)" to obtain the optimal values ​​for each dimming parameter within a certain time period.

[0067] The operating principle block diagram of the adaptive dimming system in this technical solution is as follows: Figure 4As shown, the intelligent control unit 1 for cabin lighting collects passenger information and dimming status information through the ship's network communication server 2. This information is then transmitted to the data acquisition module 12 via the network protocol reading and conversion module 13. After processing and storing the relevant data, the acquisition module supplies it to the data analysis module 11 for data analysis and generation (or updating) of optimal dimming parameters. The generated results (optimal setting values ​​for each dimming parameter for different time periods and different passenger groups) are converted into network transmission data (IP address + dimming information) by the control command generation module 14, and then transmitted to each living quarters on time and accurately through the network switch 3. The entire ship's network dimming path uses CAT-6A cables to achieve high-speed and stable transmission of dimming commands.

[0068] Based on the operating principle of the above system, its ship-wide network dimming control logic is as follows: Figure 5 As shown, at the start of a new voyage, based on passenger registration information and the current optimal dimming logic settings, corresponding dimming commands are generated for each customer group, enabling online dimming control throughout the ship. During the voyage, the system continuously collects manual dimming status information from customers. After each voyage, the dimming needs of various customer groups are further analyzed and statistically processed to generate new dimming logic settings. This process modifies and updates various parameter settings from the previous voyage. This iterative process ensures that the lighting environment in all cabins increasingly meets the actual needs of different passenger groups, truly achieving adaptive dimming.

[0069] As can be seen from the above technical solutions, the adaptive dimming system provides a scientific and comfortable lighting environment for different passenger groups through a ship-wide network dimming control method and supporting dimming equipment. At the same time, the cabin interior adopts a combination of automatic and manual dimming to maximize the satisfaction of the personalized lighting needs of different customers. Furthermore, by collecting a large number of feedback samples of the actual manual dimming needs of various types of customer groups, and through big data analysis and statistics, it obtains better parameter settings, so that the cabin lighting environment is continuously optimized adaptively, thereby continuously improving the customer's stay experience and thus improving the economic benefits of the cruise market. In addition, the networked design facilitates the future functional expansion and upgrade of the dimming system.

[0070] This invention also provides a ship that employs the adaptive dimming system described in the above embodiments to control the dimming of lights in various cabins. This system possesses all the beneficial effects of the aforementioned embodiments, providing a scientifically comfortable lighting environment for different passenger groups through a ship-wide network dimming control system and supporting dimming equipment. Simultaneously, the cabin interiors combine automatic and manual dimming to maximize the satisfaction of individual lighting needs from different customers. Furthermore, by collecting extensive feedback samples of actual manual dimming needs from various customer groups and conducting big data analysis and statistics, it derives optimal parameter settings, enabling the cabin lighting environment to adaptively and continuously optimize, thereby continuously improving the passenger experience and enhancing the economic benefits of the cruise market. In addition, the networked design facilitates the future functional expansion and upgrades of the dimming system.
