Description

Technical Field

[0001] The present invention relates to the technical field of tunnel intelligent lighting, and in particular to a tunnel intelligent lighting monitoring system and method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Railway tunnel lighting systems primarily provide essential lighting support for tunnel inspections and construction activities, as well as reliable emergency lighting for the evacuation of passengers and staff in the event of a train malfunction. Traditional railway tunnel lighting systems typically rely on technologies such as photoelectric sensors, infrared beams, or ultrasonic sensors to monitor train status. These sensors determine whether a train is stationary by detecting signal obstruction. However, due to the complex tunnel environment, factors such as dust and condensation can easily block signal feedback. Furthermore, tunnel vibration can cause signal offsets, potentially leading to false detections and prolonged lighting operation, a phenomenon known as "eternal lighting." This not only significantly wastes power but also increases operating costs. Summary of the Invention

[0004] To address the above-mentioned issues, the present invention proposes an intelligent tunnel lighting monitoring system and method. By detecting the vehicle's location, the system controls all lights between the vehicle's location and the nearest tunnel safety exit to turn on, thereby providing effective guidance for passengers and saving energy.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] First, an intelligent tunnel lighting monitoring system is proposed, which includes a vehicle speed detection device, a positioning device, a monitoring background, and multiple lighting lamps installed in the tunnel;

[0007] The vehicle speed detection device is used to continuously monitor the driving status of the vehicle when entering the tunnel and after entering the tunnel.

[0010] Furthermore, the vehicle speed detection device is used to determine that the vehicle's driving state is that the vehicle is parked in a tunnel when it is determined, based on the vehicle's driving state information, that the vehicle's driving speed is 0, or that the vehicle's current driving speed is less than the driving speed at the previous moment, and the difference between the current driving speed and the driving speed at the previous moment is greater than a set error.

[0011] Furthermore, the positioning device is used to obtain the position information of the vehicle when entering the tunnel; based on the position information when entering the tunnel, the vehicle's driving status information and the time information when the vehicle's driving status is obtained, the real-time position information of the vehicle in the tunnel is calculated and determined.

[0012] Furthermore, all lighting fixtures in the tunnel are divided into zones, each zone including multiple lighting fixtures. The lighting fixtures in each zone are connected to the intelligent lighting processing device in that zone, and the monitoring background is in communication with all the intelligent lighting processing devices.

[0016] Intelligent power collection module, used to obtain real-time power consumption data of lighting lamps and send the power consumption data to the monitoring background;

[0017] The self-check module is used to monitor the working status of the lighting and determine whether the lighting is abnormal; when it is determined that the lighting is abnormal, the lighting abnormality information is sent to the monitoring background.

[0019] Furthermore, the vehicle speed detection device includes a plurality of vehicle speed detection radars, and the plurality of vehicle speed detection radars are installed at a preset distance at the tunnel entrance and on the inner wall of the tunnel.

[0020] Furthermore, the positioning devices are installed at the tunnel entrance and tunnel exit.

[0021] Furthermore, a plurality of lighting lamps are arranged at intervals along the length direction of the tunnel.

[0022] Secondly, a tunnel intelligent lighting monitoring method is proposed, including:

[0023] The vehicle speed detection device continuously monitors the driving status of the vehicle when entering the tunnel and after entering the tunnel. When the vehicle's driving status is detected as a stop in the tunnel, the vehicle stop information is sent to the monitoring background;

[0024] The vehicle's position is located by the positioning device to obtain the vehicle's real-time position information in the tunnel;

[0025] When the monitoring background receives the vehicle parking information, it obtains the vehicle's parking position through the positioning device;

[0026] Determine the tunnel safe exit closest to the vehicle's parking location;

The system includes a vehicle speed detection device, a positioning device, a monitoring backend, and multiple lights installed in the tunnel. The vehicle speed detection device is used to continuously monitor the driving status of a vehicle entering and after entering the tunnel. When the vehicle's driving status is detected as being stopped in the tunnel, the monitoring backend sends vehicle stop information to the monitoring backend. The positioning device is used to locate the vehicle's position and obtain real-time location information of the vehicle in the tunnel. The monitoring backend, upon receiving the vehicle stop information, is used to obtain the vehicle's stop position through the positioning device, determine the tunnel emergency exit closest to the vehicle's stop position, and control the activation of all lights between the vehicle's stop position and the tunnel emergency exit closest to the vehicle's stop position. By monitoring the vehicle's driving status, when it is determined that the vehicle is stopped in the tunnel, the vehicle's stop position and the nearest emergency exit can be accurately determined. Finally, all lights between the stop position and the nearest emergency exit are controlled to illuminate in a targeted manner, thereby providing effective lighting for passengers on the vehicle and providing guidance to passengers' escape routes through the illuminated lights, while preventing excessive energy consumption when all lights are illuminated.

[0041] Example 1

[0042] In order to achieve intelligent control of the switching of tunnel lights and solve the technical problem of high energy consumption caused by the lights in the tunnel being always on, this embodiment discloses a tunnel intelligent lighting monitoring system. The vehicle's driving status is monitored by a vehicle speed detection device, and the position of the vehicle when entering the tunnel is located by a positioning device. The vehicle's driving status is used to determine whether the vehicle is parked in the tunnel. When it is determined that the vehicle is parked in the tunnel, the vehicle's parking position is determined based on the vehicle's driving status and the position when entering the tunnel, and the tunnel safety exit closest to the vehicle's parking position is determined. Finally, all the lights between the vehicle's parking position and the nearest tunnel safety exit are controlled to turn on, thereby providing effective lighting for passengers on the vehicle. The turned-on lights can also provide guidance for passengers' escape routes, allowing passengers to exit the tunnel as quickly as possible. In addition, through the intelligent control of the lights on, the problem of high energy consumption caused by the lights being always on is avoided.

[0043] Combine Figure 1-Figure 4 , the tunnel intelligent lighting monitoring system disclosed in this embodiment is described in detail.

[0044] The intelligent tunnel lighting monitoring system disclosed in this embodiment includes a vehicle speed detection device, a positioning device, a monitoring backend, and multiple lighting lamps installed in the tunnel;

[0045] The vehicle speed detection device is used to continuously monitor the driving status of the vehicle when entering the tunnel and after entering the tunnel. When the driving status of the vehicle is detected as the vehicle stopping in the tunnel, the vehicle stopping information is sent to the monitoring background;

[0046] Positioning device, used to locate the position of the vehicle and obtain the real-time position information of the vehicle in the tunnel;

[0047] The monitoring background is used to obtain the vehicle's parking position through the positioning device after receiving the vehicle parking information; determine the tunnel safety exit closest to the vehicle parking position; and control all the lights between the vehicle parking position and the tunnel safety exit closest to the vehicle parking position to turn on.

[0048] In this embodiment, a plurality of lighting lamps are installed in the tunnel, and the plurality of lighting lamps are arranged at intervals along the length direction of the tunnel.

[0049] like Figure 4 As shown, multiple lighting fixtures are evenly spaced along the length of the tunnel, and all lighting fixtures in the tunnel are divided into zones. Each zone includes multiple lighting fixtures, and an intelligent lighting processing device is set up in each zone. The lighting fixtures in each zone are connected to the intelligent lighting processing device in that zone, and the monitoring background is in communication with all intelligent lighting processing devices.

[0050] Intelligent lighting processing device, used to control the turning on and off of lights in the area;

[0051] The monitoring background is used to turn on and off the lights in the area where the intelligent lighting processing device is located by controlling the intelligent lighting processing device.

[0052] Ideally, an intelligent lighting processing device is installed every 300 meters from the tunnel entrance. These devices can be used to select whether to turn the lights in their area on or off. Furthermore, each intelligent lighting processing device can also control the on / off of all lights in the tunnel. In addition to being able to turn the lights in their area or all lights in the tunnel on and off based on control signals sent by the monitoring backend, the intelligent lighting processing device also has a manual on / off function. When tunnel inspections, construction activities, or when automatically activated lights are ineffective, the lights in their area or all lights in the tunnel can be manually turned on or off.

[0053] In this embodiment, each intelligent lighting processing device and lighting lamp is equipped with a power carrier communication module. The intelligent lighting processing device uses power carrier technology to establish unilateral communication with the tunnel lamp. The lighting lamp does not communicate directly with the monitoring background, but communicates with the monitoring background through the intelligent lighting processing device to make command judgments and status feedback.

[0054] The intelligent lighting processing device is used to control the on / off and status of tunnel lighting. If communication anomalies between the intelligent lighting processing device and the monitoring backend or other factors prevent the tunnel lighting from being automatically started or shut down, the intelligent lighting processing device can be used to manually turn the lights on or off locally.

[0055] The lighting lamps adopt the single lamp control function. The monitoring background can send a command to the intelligent lighting processing device to turn off or turn on the lighting lamps. After receiving the command from the monitoring background, the intelligent lighting processing device will perform individual switch control and brightness adjustment on the lighting lamps in the area.

[0056] In this embodiment, an intelligent power collection module and a self-test module are set in each lighting lamp;

[0057] Intelligent power collection module, used to obtain real-time power consumption data of lighting lamps and send the power consumption data to the monitoring background;

[0058] The self-check module is used to monitor the working status of the lighting and determine whether there is any abnormality in the lighting. When it is determined that the lighting is abnormal, the lighting abnormality information is sent to the monitoring background to remind relevant personnel to replace the damaged lighting in time.

[0059] Preferably, the self-test module is used to obtain key data such as the current, voltage and temperature of the lighting lamp, and analyze the current, voltage and temperature of the lighting lamp to determine whether there is an abnormality in the lighting lamp; specifically: when the current fluctuation exceeds the preset current safety fluctuation range, or the voltage fluctuation exceeds the preset voltage safety fluctuation range, or the temperature exceeds the preset temperature safety threshold, it is determined that there is an abnormality in the lighting lamp.

[0060] During specific implementation, the intelligent power collection module and the self-test module are both connected to the monitoring background through the intelligent lighting processing device.

[0061] In this embodiment, the intelligent lighting processing device, speed detection device, and positioning device are all connected to the monitoring backend via 5G-R communication. All terminal devices communicate wirelessly with the monitoring backend via 5G-R communication, enabling operations such as train speed and position monitoring, lighting status monitoring, and remote lighting control.

[0062] This embodiment continuously monitors the driving status of the vehicle when entering and after entering the tunnel through the vehicle speed detection device. When the driving status of the vehicle is monitored as the vehicle stopping in the tunnel, the vehicle stopping information is sent to the monitoring background.

[0063] like Figure 2 As shown, the vehicle speed detection device includes multiple vehicle speed detection radars, which are installed at the tunnel entrance and the inner wall of the tunnel at preset distances. One vehicle speed detection radar is set at every set distance on the inner wall of the tunnel to ensure continuous monitoring of the vehicle's driving status.

[0064] When the speed detection device detects a sudden drop in speed or a stop, it immediately reports this to the monitoring backend via 5G-R communication. The backend automatically retrieves the vehicle's parking location from the positioning device and activates all lights between the parking location and the nearest tunnel exit, providing escape route guidance for tunnel occupants and reliable emergency lighting for emergency evacuations.

[0065] Preferably, a vehicle speed detection radar is set every 500 meters in the tunnel.

[0066] During specific implementation, the vehicle's driving state information acquired by the vehicle speed detection device includes the vehicle's driving speed.

[0067] The vehicle speed detection device is used to determine that the vehicle's driving state is that the vehicle is parked in a tunnel when it is determined based on the vehicle's driving state information that the vehicle's driving speed is 0, or that the vehicle's current driving speed is less than the driving speed at the previous moment, and the difference between the current driving speed and the driving speed at the previous moment is greater than a set error.

[0068] This embodiment locates the position of the vehicle through a positioning device to obtain real-time position information of the vehicle in the tunnel.

[0069] Specifically, the positioning device is used to obtain the position information of the vehicle when entering the tunnel; based on the position information when entering the tunnel, the vehicle's driving status information and the time information when the vehicle's driving status is obtained, the real-time position information of the vehicle in the tunnel is calculated and determined.

[0070] like Figure 3 As shown, positioning devices are installed at the tunnel entrance and exit. The positioning devices use Beidou edge computing devices to receive Beidou satellite navigation system (BDS) signals. When a vehicle reaches the tunnel entrance, the speed detection device acquires the vehicle's driving status and records the time of acquisition. The vehicle's driving status and time at this location represent the vehicle's driving status and the time when the vehicle entered the tunnel. At this point, the positioning device acquires the vehicle's position at the tunnel entrance, which is defined as the vehicle's position at the time of entry.

[0071] The positioning device calculates the real-time position information of the vehicle in the tunnel based on the position information of the vehicle when entering the tunnel, the driving status of the vehicle when entering the tunnel, the time when the vehicle enters the tunnel, the real-time driving status of the vehicle after entering the tunnel, and the time of obtaining the real-time driving status.

[0072] The positioning device calculates the vehicle's position information based on the time when the vehicle speed detection device detects that the vehicle is parked in the tunnel, which is the vehicle's parked position.

[0073] The monitoring background of this embodiment includes a system workstation, a data server and communication equipment.

[0074] The system workstation is used for human-computer interaction between users and the monitoring background, as well as business interface display and operation. The system workstation can display the driving status and location of the vehicle.

[0075] The data server is used for data access, cleaning, storage and consumption, and the data comes from data provided by various terminals.

[0076] Specifically, the data server is used to receive information sent by the intelligent lighting processing device, the power collection module, the self-test module, the vehicle speed detection device and the positioning device. After receiving the vehicle parking information, it obtains the vehicle's parking position through the positioning device; determines the tunnel safety exit closest to the vehicle parking position; and controls all the lights between the vehicle parking position and the tunnel safety exit closest to the vehicle parking position to turn on.

[0077] The data server conducts 5G-R communication with the intelligent lighting processing device, lighting, vehicle speed detection device and positioning device through communication equipment.

[0078] The intelligent tunnel lighting monitoring system proposed in this embodiment uses Beidou edge computing devices at both ends of the tunnel entrance to accurately capture the time and location of trains entering the tunnel. Combined with a speed detection device, it provides real-time train location and monitoring of vehicle driving status. When the speed detection device detects a vehicle stopping in the tunnel, it automatically feeds this information back to the monitoring backend. Upon receiving this information, the monitoring backend retrieves the vehicle's stopping position as determined by the positioning device and quickly issues power-on commands to all lights between the vehicle's stopping position and the nearest tunnel exit. These commands, transmitted through the intelligent lighting processing device, activate all lights in the tunnel from the train's stopping position to the nearest exit, providing escape route guidance for tunnel occupants and ensuring safe and rapid evacuation in an emergency.

[0079] The intelligent tunnel lighting monitoring system disclosed in this embodiment can remotely activate lights in specific areas under specific circumstances, such as during tunnel inspections or construction activities. This remote control function greatly facilitates the work of maintenance personnel and improves work efficiency. If network anomalies prevent remote operation, maintenance personnel can directly operate the intelligent lighting processing device locally to turn lights on and off, ensuring the continuity and reliability of tunnel lighting.

[0083] The vehicle's position is located by the positioning device to obtain the vehicle's real-time position information in the tunnel;

[0084] When the monitoring background receives the vehicle parking information, it obtains the vehicle's parking position through the positioning device;

[0085] Determine the tunnel safe exit closest to the vehicle's parking location;
