[0028] like Figures 1 to 5 The diagram illustrates an embodiment of this utility model, relating to a lighting sensing system based on urban rail transit communication. The system includes a heat dissipation lighting module 10, a sensing module 20, a communication module 30, a control module 40, and a power supply module 50. The heat dissipation lighting module 10 provides lighting for the rail transit system and is electrically connected to the sensing module 20, communication module 30, and control module 40. The sensing module 20 collects rail transit environmental data. The communication module 30 transmits data. The control module 40 processes the sensing data and regulates the operating status of the lighting fixtures. The power supply module 50 supplies power to the heat dissipation lighting module 10, sensing module 20, communication module 30, and control module 40.
[0029] Furthermore, in the rail transit scenario, the heat dissipation lighting module 10 is electrically connected to the sensing module 20, communication module 30, and control module 40, respectively. This electrical connection enables the sensing module 20 to monitor environmental information in real time, such as light intensity and human infrared sensors, and then transmit this information to the control module 40. The control module 40 can analyze and process this information; for example, when the human infrared sensor detects someone approaching, the control module 40 can adjust the brightness of the lights. The electrical connection to the communication module 30 enables bidirectional data transmission, allowing the status information of the lights to be transmitted to a remote monitoring terminal, and also receiving remote control commands to adjust the lights. This connection method makes the entire system more intelligent and efficient, better meeting the lighting needs of different rail transit scenarios.
[0030] Furthermore, the heat dissipation lighting module 10 is a multi-set LED lighting fixture applied in rail transit scenarios. The heat dissipation lighting module 10 includes a housing 60, a heat dissipation structure 70, a light source assembly 80, and an electrical connection terminal 90. The housing 60 has a frustum-shaped design, and its front end narrows to form a light outlet 61. The light outlet 61 has a circular opening structure. The heat dissipation structure 70 is disposed around the periphery of the housing 60. The light source assembly 80 is located at the light outlet 61 at the front end of the housing 60. The electrical connection terminal 90 is located at the rear of the housing 60 and includes two port interfaces 91, which are used to input power from the power module 50 to the drive circuit. Specifically, by setting up multiple sets of LED lighting fixtures, the spacing can be increased in tunnels, and an array layout can be adopted in station halls. This allows for flexible arrangement according to the size of the track space, adapting to the lighting needs of different areas. The frustum-shaped housing 60 increases the heat dissipation area, and the radial blades accelerate air convection, reducing the temperature of the LED light source and extending the life of the lighting fixtures. In rail transit tunnels with poor ventilation, efficient heat dissipation can avoid light decay and malfunctions caused by high temperatures.
[0031] Furthermore, the housing 60 has a functional cavity 62 inside, which is used to fix the light source assembly 80 and accommodate the driving circuit (not shown in the figure). The driving circuit (not shown in the figure) is used to convert the power input from the power module 50 into a voltage and current suitable for the operation of the light source assembly 80. Specifically, by integrating the light source and the driving circuit (not shown in the figure) into the same cavity, the size of the lamp is reduced, making it suitable for installation in narrow spaces in rail transit and allowing for embedded installation in tunnel walls.
[0032] Furthermore, the light outlet 61 is equipped with an optical lens 63, which is used to adjust the projection angle of the light source and the uniformity of the light. Specifically, the lens can adjust the beam angle, such as converting divergent light into focused light, which is suitable for different scenarios: narrow-angle lenses are used in tunnels to enhance guidance, and wide-angle lenses are used in station halls to improve the uniformity of illumination; precise light control reduces ineffective lighting areas and lowers system energy consumption.
[0033] Furthermore, the heat dissipation structure 70 is a radial blade-type heat dissipation structure, which is used to increase the heat dissipation area. Specifically, the radial blade-type heat dissipation structure increases the heat dissipation area, accelerates heat conduction, avoids LED light source attenuation due to high temperature, and improves system reliability.
[0034] Furthermore, the light source assembly 80 includes a PCB circuit board 81 and a plurality of LED beads 82. The PCB circuit board 81 is fixed inside the housing 60, and the plurality of LED beads 82 are evenly distributed on one side of the PCB circuit board 81. Specifically, the arrangement of the PCB circuit board 81 and the plurality of LED beads 82 effectively ensures the stability of the light source and the uniformity of light output.
[0035] Furthermore, the sensing module 20 includes a light intensity sensor 21, a human infrared sensor 22, and a temperature and humidity sensor 23. The light intensity sensor 21 is used to collect light intensity data within the rail transit space; the human infrared sensor 22 is used to collect data on the activity status of people within the rail transit space; and the temperature and humidity sensor 23 is used to collect environmental temperature and humidity data within the rail transit space. Specifically, the light intensity sensor 21 monitors natural light in real time and automatically adjusts the brightness of artificial lighting, such as automatically adjusting the brightness at tunnel entrances based on external light, effectively saving energy; the human infrared sensor 22 detects human activity, achieving "lights on when people are present, lights off when people are absent," such as reducing brightness on platforms during low passenger flow late at night; the temperature and humidity sensor 23 data is used to predict equipment malfunctions, such as issuing warnings of condensation risk when humidity abnormally increases; and multi-sensor data fusion can improve the accuracy of system decision-making, such as optimizing heat dissipation strategies by combining temperature, humidity, and light data.
[0036] Furthermore, the communication module 30 is either a wireless communication module or a wired communication module, used to upload sensing data and issue control commands. The wireless communication module includes Wi-Fi, Bluetooth, ZigBee, or 5G communication; the wired communication module includes RS485 bus communication. Specifically, RS485 bus communication is used in the tunnel, which has strong anti-interference capabilities and is suitable for stable transmission over long distances (several kilometers). Wi-Fi or 5G communication is used in the station hall or platform, supporting real-time data upload to the control center for remote monitoring. In some embodiments, it supports access to the rail transit integrated monitoring system and linkage with security, ventilation, and other systems, such as automatically switching emergency lighting modes in case of fire.
[0037] Furthermore, the control module 40 is an STM32H743VI microprocessor. Specifically, the STM32H743VI microprocessor has high-performance processing capabilities. Based on this, the control module 40 can have built-in data processing algorithms to generate lamp brightness adjustment and on / off control commands based on the environmental data collected by the sensing module 20, thereby regulating the working state of the light source component 80.
[0038] Furthermore, the power module 50 includes an AC power input interface, a voltage regulator circuit electrically connected to the AC power input interface, and a backup power supply. The voltage regulator circuit converts the input power into the operating voltage for the lamps, sensing module 20, communication module 30, and control module 40. The backup power supply maintains basic power during sudden power outages in the rail transit system. Specifically, the voltage regulator circuit ensures the stability of the system's power supply and prevents voltage fluctuations from damaging the equipment; the backup power supply maintains basic lighting and communication functions, enhancing the rail transit system's emergency response capabilities.
