[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the terms "first," "second," etc., used in this application are only for the convenience of describing the technical solution and distinguishing different components, and are not intended to limit this application. To make the technical solution of this utility model clearer, it will be explained and illustrated through the following embodiments.

[0019] This embodiment provides an IoT-based intelligent power and lighting control system for ships, such as... Figure 1 As shown, the system includes sensor modules, edge computing units, and lighting modules deployed in various ship compartments. The edge computing units are connected to the sensor modules and lighting modules respectively. The system also includes a power module, an IoT gateway, and a remote monitoring terminal. The lighting modules are connected to the power module. The remote monitoring terminal is connected to the edge computing units and the power module respectively through the IoT gateway.

[0020] The system includes a sensor module for detecting multimodal data from the cabin and sending it to an edge computing unit; an edge computing unit for sending different dimming commands to a lighting module based on the multimodal data; a lighting module for adjusting the brightness of the cabin based on the dimming commands; a power module for supplying power to the lighting module; an IoT gateway for establishing communication between the power module, the edge computing unit, and a remote monitoring terminal; and a remote monitoring terminal for acquiring multimodal data from the cabin via the edge computing unit and power status data via the power module, displaying and monitoring these data, and also for receiving user commands and sending them to the power module and the edge computing unit for active dimming and power control.

[0021] Specifically, the power module in this embodiment includes a main power supply, a redundant power supply, a first relay, a second relay, a power switching controller, and a DC bus. The main power supply is connected to the DC bus via the first relay, and the redundant power supply is connected to the DC bus via the second relay. The control terminals (coil terminals) of the first and second relays are connected to the power switching controller, allowing the controller to control the on / off state of the first and second relays, thereby controlling the switching between the main power supply and the redundant power supply. The DC bus is connected to the lighting module to supply power. The power switching controller is connected to both the main power supply and the redundant power supply to acquire power status data, including remaining power, voltage, current, and temperature, and controls the switching between the main power supply and the redundant power supply based on this data. The power switching controller is also connected to the remote monitoring terminal via the IoT gateway, allowing it to actively control the switching between the main power supply and the redundant power supply based on input commands from the remote monitoring terminal. The use of redundant power supplies ensures that the lighting module in this embodiment continues to supply power even in the event of a main power supply failure or insufficient power, meeting the ship's lighting requirements.

[0022] Preferably, the power switching controller in this embodiment adopts a battery management system (BMS), which has mature battery monitoring and control functions and is widely used in the field of battery management for vehicles and ships, saving development time.

[0023] The lighting module in this embodiment includes a Zigbee communication module, a PWM dimming driver, and an LED light box. The Zigbee communication module is connected to both the edge computing unit and the PWM dimming driver. The PWM dimming driver is connected to the LED light box. The LED light box is connected to the power supply module, i.e., the DC bus is connected to the light box. The Zigbee communication module establishes communication between the PWM dimming driver and the edge computing unit, suitable for short-distance communication. It is used to obtain dimming commands from the edge computing unit and send them to the PWM dimming driver. Correspondingly, the PWM dimming driver adjusts the brightness of the LED light box according to the lighting brightness requirements of the dimming commands using PWM. Based on the PWM dimming method, stepless brightness adjustment from 0-100% is supported.

[0024] In this embodiment, the sensor module includes an illuminance sensor and a human infrared sensor, which are respectively connected to the edge computing unit.

[0025] An illuminance sensor collects cabin illuminance data and sends it to the edge computing unit. The edge computing unit can then adjust the lighting brightness according to different illuminance levels. For example, when the illuminance is greater than 300 lux, the lighting brightness is set to 30% of the maximum brightness. Illuminance-based control logic is existing technology and can be implemented using simple logic gates. In practice, the user can flexibly set the brightness based on the actual situation. A human infrared sensor detects whether there are people in the cabin and sends the data to the edge computing unit. The edge computing unit can then further reduce or increase the lighting brightness to save energy based on the presence of people in the cabin. For example, when the illuminance is greater than 300 lux, the default lighting brightness is 30% of the maximum brightness. If someone is detected in the cabin, the lighting brightness can be increased to 40% of the maximum brightness; if no one is detected, the lighting brightness can be reduced to 15% of the maximum brightness. Human presence-based control logic is also existing technology and can be implemented using simple logic gates. In practice, the user can flexibly set the brightness based on the actual situation.

[0026] In addition, the sensor module of this embodiment also includes a current transformer, which is connected to the edge computing unit and installed in the compartment's electrical distribution box. The current transformer is used to detect the current in the electrical distribution box and send it to the edge computing unit. The edge computing unit can then calculate the load factor of the corresponding compartment based on the real-time electrical distribution box current and a constant voltage (load factor calculation is prior art), and adjust the lighting brightness according to the load factor. For example, when the illuminance is greater than 300 lux, the lighting brightness is set to 30% of the maximum brightness; if the load factor is greater than 75%, the lighting brightness is set to 10% of the maximum brightness. The lighting brightness can then be further reduced or increased based on personnel activity. The load factor-based control logic is prior art and can be implemented even with simple logic gates. In specific implementation, the user can flexibly set the logic according to the actual situation. The use of the current transformer allows this application to automatically adjust the lighting brightness according to the compartment's load factor, further saving energy.

[0027] It should be noted that this application, through the installation of illuminance sensors, human infrared sensors, and current transformers, achieves the collection of illuminance, personnel status, and load rate. This allows for the adjustment of lighting brightness based on illuminance, personnel status, and load rate. The specific adjustment method described in this application is merely an example; in actual implementation, the user should flexibly set it according to the actual situation. For instance, the edge computing unit can uniformly send illuminance, personnel status, and load rate to a remote monitoring terminal, allowing the user to decide how to adjust the lighting.

[0028] This embodiment also proposes a ship that includes the above-described IoT-based intelligent power and lighting control system for ships.

[0029] In summary, this application provides an IoT-based intelligent power and lighting control system for ships. Through hardware collaboration among sensor modules, edge computing units, lighting modules, power modules, IoT gateways, and remote monitoring terminals, the system enables ship lighting to automatically adjust brightness based on real-time illuminance, personnel status, and load rate, saving energy and improving automation. Furthermore, the IoT-based system allows for remote control and monitoring of the lighting modules, facilitating user operation and enhancing the user experience.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
