They include traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels. In traffic tunnels, multiple sets of lighting devices are typically evenly distributed at a specified density based on the maximum driving speed within the tunnel to provide illumination for vehicles entering. However, in using existing technology, the inventors have discovered at least the following problems:
[0003] Currently, traffic tunnel lighting is continuously on both day and night. However, sometimes there are few vehicles in the traffic tunnel, especially in traffic tunnels on highways, and the lighting is still on, resulting in huge electricity consumption for traffic tunnel lighting.
[0004] In addition, existing technologies typically set the lighting power of traffic tunnel lighting devices for different time periods based on the maximum brightness outside the traffic tunnel throughout the year. However, this control method is relatively simple and cannot meet the complex changes in natural light at different times, which is not conducive to drivers quickly adapting to the tunnel environment. It also results in the waste of lighting resources. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] In a first aspect, the present invention provides a method for controlling lighting in a traffic tunnel, comprising:
[0008] The system receives vehicle detection information in real time from the vehicle detection module, which is located at the entrance section outside the traffic tunnel.
[0009] Based on the incoming vehicle detection information, the time it takes for the incoming vehicle to enter the tunnel is obtained;

[0050] Figure 3 This is a block diagram of an electronic device in one embodiment. Detailed Implementation
[0051] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.
[0052] Example 1:
[0053] This embodiment discloses a traffic tunnel lighting control method, which can be executed by, but is not limited to, a computer device or virtual machine with certain computing resources, such as a personal computer, smartphone, personal digital assistant or wearable device, or by a virtual machine, in order to reduce lighting energy consumption in traffic tunnels.
[0054] like Figure 1 As shown, a traffic tunnel lighting control method may include, but is not limited to, the following steps:
[0055] S1. Receive vehicle detection information sent by the vehicle detection module in real time; wherein, the vehicle detection module is set at the entrance section outside the traffic tunnel; specifically, the vehicle detection module can be located 200-500 meters away from the entrance of the traffic tunnel so that the lighting device of the entrance section in the traffic tunnel can be operated before the vehicle enters the traffic tunnel.
[0056] In this embodiment, the vehicle detection information includes vehicle arrival information and vehicle speed information matching the vehicle arrival information;
[0057] Correspondingly, based on the vehicle speed information in the incoming vehicle detection information, the time it takes for the incoming vehicle to enter the tunnel is obtained; wherein, the time it takes for the incoming vehicle to enter the tunnel is:
[0058] t' = L' / v';
[0059] In the formula, L' is the distance between the vehicle detection module and the traffic tunnel, and v' is the vehicle speed information.
[0060] Specifically, in this embodiment, the vehicle arrival detection module includes a vehicle arrival detection module and a vehicle speed detection module. The vehicle arrival detection module runs continuously. When the vehicle arrival detection module detects an approaching vehicle, it outputs the vehicle arrival information to the main control module, so that the main control module can drive the vehicle speed detection module to run and detect the vehicle speed information. Of course, both the vehicle arrival detection module and the vehicle speed detection module can run continuously and detect. In this embodiment, the vehicle arrival detection module runs continuously, while the vehicle speed detection module is in sleep mode. The vehicle speed detection module only runs when the vehicle arrival detection module detects an approaching vehicle, thereby increasing the running time of the vehicle arrival detection module and further saving energy.
[0061] S2. Based on the incoming vehicle detection information, obtain the time it takes for the incoming vehicle to enter the tunnel;
[0062] S3. The ambient brightness outside the traffic tunnel is collected by a light detection module; wherein, the light detection module is located outside the traffic tunnel;
[0063] S4. Based on the ambient brightness and the preset tunnel section of the traffic tunnel, obtain the lighting brightness control model of the traffic tunnel;
[0064] Because the human eye needs time to adapt to changes in brightness, visual problems such as "white holes" and "black holes" can easily occur. Therefore, drivers may experience a certain degree of blind spot when entering or exiting traffic tunnels, posing a significant hazard to safe driving. To avoid this problem of blind spot and potential safety hazards for drivers when entering or exiting traffic tunnels, in this embodiment, the tunnel section includes an entrance section, a transition section, an intermediate section, and an exit section arranged sequentially from the entrance to the exit of the traffic tunnel.
[0065] The lighting brightness control model includes the brightness of the lighting devices corresponding to the lead-in section, the transition section, the intermediate section and the lead-out section, respectively, as well as the output power matched with the corresponding brightness.
[0066] To further reduce lighting energy consumption in traffic tunnels, in this embodiment, the brightness of the i-th tunnel segment in the traffic tunnel is:
[0067] L i =k i *L0;
[0068] In the formula, k i Li is the luminance reduction factor for the i-th tunnel segment in the traffic tunnel; L0 is the ambient luminance outside the traffic tunnel (cd / m2). 2 ).
[0069] It should be understood that the luminance reduction coefficients differ between different tunnel sections within a traffic tunnel, and the luminance reduction coefficient for the same tunnel section also differs at different times of day. For example, if the time period is divided into daytime and nighttime periods, then during the daytime period, the luminance reduction coefficient k for each tunnel section will vary. i ≤1, as an example, in this embodiment, the brightness reduction factor k of the introduction segment, transition segment, middle segment, and lead-out segment is 1. i Set them to 1, 2 / 3, 1 / 3 and 2 / 3 in sequence.
[0070] In this embodiment, the tunnel section of the traffic tunnel is divided into an entrance section, a transition section, an intermediate section, and an exit section, and different brightness reduction coefficients k are set for different tunnel sections. i This helps drivers quickly adapt to the brightness inside traffic tunnels, while also reducing the brightness reduction factor k in the middle section of the traffic tunnel. i Setting it to minimum will make it easier to further save on lighting energy consumption.
[0071] In this embodiment, the length of the introduced segment is:
[0072] D1 = 1.154D s -[(h-15) / tan10°];
[0073] In the formula, D s For parking sight distance, V is the vehicle speed (km / h); t is the reaction time (s); ψ is the coefficient of adhesion between the vehicle and the road surface of the traffic tunnel; h is the longitudinal slope of the road surface of the traffic tunnel; and h is the clearance height (m) at the entrance of the traffic tunnel.
[0074] Speed limits in highway tunnels are 60 to 80 kilometers per hour, while speed limits in tunnels on general urban roads are 40 to 60 kilometers per hour. In this embodiment, the driving speed can be specified as the median value of the tunnel speed limit, or it can be specified as the real-time detected vehicle speed.
[0075] S5. Based on the time it takes for the oncoming vehicle to enter the tunnel, the lighting module is activated by operating the lighting device located in the lead-in section of the preset traffic tunnel at a specified time before the vehicle enters the tunnel; wherein, the lighting module is installed in the traffic tunnel, and the lighting module includes multiple sets of lighting devices evenly distributed in the traffic tunnel along the direction from the entrance to the exit of the traffic tunnel; the time it takes for the oncoming vehicle to enter the tunnel can be obtained based on the time it takes for the vehicle to enter the tunnel, and thus the lighting module is activated by operating the lighting device located in the lead-in section of the preset traffic tunnel at a specified time before the vehicle enters the tunnel.
[0076] S6. Receive in real time the vehicle entry detection information sent by the vehicle entry detection module; wherein, the vehicle entry detection module is set inside the traffic tunnel; specifically, the vehicle entry detection module is set on the road surface or side wall of the traffic tunnel, which is not limited here.
[0077] In this embodiment, the entering vehicle detection information includes entering vehicle arrival information and entering vehicle speed information matching the entering vehicle arrival information. Multiple entering vehicle detection modules are provided, and these modules are arranged along the entrance to exit direction within the traffic tunnel. The method further includes:
[0078] Construct a vehicle speed prediction model;
[0079] The vehicle speed prediction model is trained based on multiple sample vehicle speed information within the traffic tunnel to obtain the trained vehicle speed prediction model.
[0080] Correspondingly, there are multiple types of vehicle entry detection information. After receiving the vehicle entry detection information sent by the vehicle entry detection module, the method further includes:
[0081] The speed information of multiple incoming vehicles is sequentially input into the trained incoming vehicle speed prediction model to obtain the speed sequence information of the incoming vehicles. This allows the multiple lighting devices in the lighting module to perform lighting actions along with the vehicle based on the speed sequence information of the incoming vehicles and the lighting brightness control model.
[0082] Specifically, in this embodiment, the vehicle entry detection module includes a vehicle arrival detection module and a vehicle speed detection module. The vehicle arrival detection module runs continuously. When the vehicle arrival detection module detects a vehicle entering, it outputs vehicle arrival information to the main control module so that the main control module can drive the vehicle speed detection module to run and detect the vehicle speed information. Of course, both the vehicle arrival detection module and the vehicle speed detection module can run continuously and detect. In this embodiment, the vehicle arrival detection module runs continuously, while the vehicle speed detection module is in sleep mode. The vehicle speed detection module only runs when the vehicle arrival detection module detects a vehicle entering, thereby increasing the running time of the vehicle entry detection module and further saving energy.
[0083] In this embodiment, the vehicle speed prediction model may, but is not limited to, using a VAR (Vector Autoregressive) network model, an RBF (Radial Basis Function) neural network model, etc., and is not restricted here.
[0084] S7. Based on the incoming vehicle detection information and the lighting brightness control model, drive multiple lighting devices in the lighting module to perform lighting actions along with the vehicle.
[0085] In this embodiment, based on the incoming vehicle detection information and the lighting brightness control model, multiple lighting devices in the lighting module are driven to perform lighting actions along with the vehicle, including:
[0086] S701. Based on the incoming vehicle detection information, obtain the location information of the lighting device to be lit;
[0087] Specifically, in this embodiment, the location information of the lighting device to be turned on is obtained based on the incoming vehicle detection information, including:
[0088] Based on the speed sequence information of the incoming vehicle, the predicted position information of the incoming vehicle is obtained;
[0089] Based on the predicted location information of the incoming vehicle, the location information of the lighting devices to be lit is obtained. The location information of the lighting devices to be lit includes the location of all lighting devices to be lit at the location of the predicted location information of the incoming vehicle and the location of all lighting devices to be lit at a specified distance from the predicted location information of the incoming vehicle. The specified distance is set to 50-100 meters to facilitate the driver's visibility of the road surface in front of and behind the vehicle.
[0090] S702. Based on the output power corresponding to the lighting device to be lit at the location information of the lighting device to be lit in the lighting brightness control model, drive the lighting device to be lit to operate, and at the same time drive other lighting devices in the lighting module to turn off.
[0091] In this embodiment, multiple lighting devices operate with the vehicle. That is, while the vehicle is traveling in the traffic tunnel, the lighting modules located at the location of the oncoming vehicle and at a specified distance from the oncoming vehicle location information are controlled to operate, while other lighting modules in the traffic tunnel are controlled to turn off, thereby improving the energy-saving effect of lighting.
[0092] In this embodiment, when a designated lighting device is driven to run, the output power of the lighting device is obtained based on the brightness of the lighting device in the lighting brightness control model. Then, the lighting device is driven to run according to the output power, thereby adjusting the lighting device to the corresponding brightness in the lighting brightness control model.
[0093] This embodiment improves the lighting effect in traffic tunnels, making it easier for drivers to adapt to the tunnel environment while saving lighting energy. Specifically, in this embodiment, an approaching vehicle detection module detects approaching vehicles and acquires their detection information. The module then calculates the time it takes for the approaching vehicle to enter the tunnel. A specified time before the vehicle's entry time is reached, the lighting module is pre-activated, driving the lighting devices within a pre-defined tunnel section. After acquiring the approaching vehicle detection information, a light detection module collects the ambient brightness outside the tunnel. Based on this ambient brightness and the pre-defined tunnel section, a lighting brightness control model for the traffic tunnel is obtained. Simultaneously, the module receives real-time entry vehicle detection information from the approaching vehicle detection module. Finally, based on the entry vehicle detection information and the lighting brightness control model, multiple lighting devices within the lighting module are driven to perform lighting actions alongside the vehicle. In this process, this embodiment can control the operation of the lighting device in the lighting module according to the real-time ambient brightness outside the traffic tunnel, so that the brightness of the lighting device matches the brightness value outside the traffic tunnel, making it easier for the driver to quickly adapt to the environment inside the traffic tunnel. At the same time, by driving the lighting module in the lighting module to run with the vehicle, the lighting device can be automatically turned off after the vehicle passes, achieving the technical effect of energy saving and carbon reduction.
