Description

Technical Field

[0001] The present invention relates to the technical field of dimming control of highway tunnels, and in particular to a solar energy zero-carbon tunnel and an intelligent dimming method based on the solar energy zero-carbon tunnel. Background Art

[0002] Tunnels are widely used in the construction of expressways, national highways, and municipal roads, and are usually used to cross various complex terrains, such as mountains, rivers, cities, etc. Since tunnels are usually opened in mountains or underground, there is a lack of natural light inside, so it is necessary to install lights inside the tunnel to improve the lighting level inside the tunnel and enhance the visibility of drivers in the tunnel.

[0003] In order to maintain visibility in the tunnel, the lights in the existing tunnels need to be kept on all the time, which not only consumes a lot of electricity, but also cannot always ensure that the light intensity inside and outside the tunnel is similar. When entering and exiting the tunnel, the driver often has a "momentary visual blind spot" due to the large difference in light intensity inside and outside the tunnel, which can easily cause traffic accidents. Nowadays, there is an intelligent dimming system used in tunnels, which adjusts the intensity of the lights in the tunnel accordingly by sensing the light intensity outside the tunnel to reduce the difference in light intensity inside and outside the tunnel. However, due to the limited range of light intensity, it is difficult for the commonly used lights in the daytime to reach a level similar to the light intensity of natural light. If high-power lights are used, not only will the consumption of electricity increase, but also a larger power supply equipment will be required, and the failure rate of high-power lights will also be higher, increasing maintenance costs. In addition, high-power lights installed in the tunnel are easy to directly shine into the driver's eyes, causing light spots, affecting normal driving. Summary of the invention

[0021] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0022] Embodiment 1: Reference Figure 1 , Figure 1Schematic diagram of the structure of the solar zero-carbon tunnel in the embodiment. The solar zero-carbon tunnel in this embodiment includes a tunnel body 1, a solar shading shed 2 set up at the tunnel entrance of the tunnel body 1, a lighting system 3, an energy storage system 4 and a control terminal 5 arranged in the tunnel body 1. The control terminal 5 is connected to the lighting system 3 and the energy storage system 4 respectively, and the energy storage system 4 is connected to the lighting system 3. The solar shading shed 2 generates electricity through solar energy and transmits it to the energy storage system 4 for storage. The energy storage system 4 supplies energy to the control terminal 5 and the lighting system 3, and the control terminal 5 controls the lighting system 3. The vehicle enters the tunnel body 1 through the solar shading shed 2. During the day, the solar shading shed 2 is naturally shaded, and the light intensity in the solar shading shed 2 is less than the light intensity outside the tunnel body 1. The solar shading shed 2 naturally dims the passing vehicles. At night, the light intensity of the solar shading shed 2 near the tunnel entrance of the tunnel body 1 is greater than the light intensity of the solar shading shed 2 away from the tunnel entrance of the tunnel body 1 and outside the tunnel body 1. The control terminal 5 controls the lighting system 3 so that the light intensity at the tunnel entrance of the tunnel body 1 is between the light intensity outside the tunnel body 1 and the light intensity inside the tunnel body 1 .

[0023] The solar zero-carbon tunnel in this embodiment is a one-way tunnel used on expressways, national highways, and municipal roads. Through the setting of the solar shading shed 2, before the vehicle enters the tunnel body 1, the solar shading shed 2 can block the sunlight at the tunnel entrance of the tunnel body 1, which is equivalent to the first dimming of the light intensity, so that the light intensity inside the solar shading shed 2 is slightly lower than the light intensity outside the tunnel body 1, avoiding the driver from having a "momentary visual blind spot" due to the large difference in light intensity inside and outside the tunnel. When the vehicle then enters the tunnel body 1 from the solar shading shed 2, the control terminal 5 controls the lighting system 3 to adjust the light intensity of the internal area of ​​the tunnel body 1, which is equivalent to the second dimming of the light intensity, so that the light intensity of the internal area of ​​the tunnel body 1 is slightly lower than the light intensity of the solar shading shed 2, allowing the driver to enter the tunnel when the light intensity is gradually reduced, so that the driver's eyes can gradually adapt to the light intensity of the internal area of ​​the tunnel body 1. At the same time, solar panels are laid outside the solar shading shed 2. The solar panels can generate solar power and store the electricity in the energy storage system 4. The lighting system 3 and the control terminal 5 can be operated by the electricity in the energy storage system 4, without the need to supply additional power to the tunnel, which is more energy-saving and environmentally friendly. In addition, the solar shading shed 2 shades the sunlight once, which is equivalent to setting up a light buffer channel, so that the light intensity in the tunnel body 1 can be reduced accordingly. There is no need to set up a high-power lighting system 3 to make the light intensity in the tunnel body 1 as close as possible to the light intensity outside the tunnel body 1. It only needs to be close to the light intensity of the solar shading shed 2, thereby saving power consumption and avoiding high-power light directly hitting the driver's eyes and affecting driving.

[0024] Refer to Figure 2-Figure 4 , Figure 2 This is a side view of the solar zero-carbon tunnel in the embodiment. Figure 3 This is a lighting effect diagram of the tunnel lighting lamp in the tunnel body in the embodiment. Figure 4Another lighting effect diagram of the tunnel lighting lamp in the tunnel body in the embodiment, preferably, the lighting system 3 includes a plurality of tunnel lighting lamps 31, and the plurality of tunnel lighting lamps 31 are connected to the energy storage system 4 and the control terminal 5, and the plurality of tunnel lighting lamps 31 are arranged at the top of the tunnel body 1 along the length direction of the tunnel body 1, and the tunnel lighting lamps 31 are inclined to illuminate the vehicle driving direction from perpendicular to the ground. In specific application, in this embodiment, only one row of tunnel lighting lamps 31 are arranged in the tunnel body 1, and are arranged at the top of the tunnel body 1 along the length direction of the tunnel body 1. The tunnel lighting lamps 31 adopt COB-LED tunnel lamps. Compared with the high-pressure sodium lamps in traditional tunnels, COB-LED tunnel lamps have lower energy consumption and more concentrated light sources. Moreover, the lamps in traditional tunnels are arranged symmetrically on both sides, which will cause a large amount of light scattering, thereby causing waste of light sources. In this embodiment, only one row of tunnel lighting lamps 31 are arranged at the top of the tunnel body 1, which can more concentratedly illuminate the light source in the vehicle driving area of ​​the tunnel body 1, avoiding waste of light sources. In other words, the original two rows of tunnel lights are changed into one row, so that the spacing between multiple tunnel lights 31 in this row can be reduced, so that the spacing between two adjacent tunnel lights 31 can be reduced, and the concentration of the light source can be improved. At the same time, the corresponding reduction in the power of each tunnel light 31 can also maintain the original light intensity and save energy. Furthermore, the spacing between the tunnel lights 31 near the tunnel entrance of the tunnel main body 1 is smaller than the spacing between the tunnel lights 31 in the middle of the tunnel main body 1. In other words, the light intensity of the tunnel main body 1 near the tunnel entrance is greater than the light intensity in the middle of the tunnel main body 1. When a vehicle enters the tunnel main body 1 through the solar shading shed 2, the light intensity gradually decreases before it drives to the middle of the tunnel main body 1, and then the light intensity gradually increases when it exits the tunnel from the middle of the tunnel main body 1. Specifically, the COB-LED tunnel light in this embodiment can adopt the COB-LED tunnel light disclosed in the application number CN201911123090.2. It should be noted that the tunnel lights 31 in the tunnel body 1 are kept on for 24 hours, that is, during the day when the light intensity outside the tunnel body 1 is relatively high, the tunnel lights 31 are dimmed according to the light intensity outside the tunnel body 1, and at night, extreme weather and other times when the light intensity outside the tunnel body 1 is relatively low, the tunnel lights 31 maintain the minimum standard illumination to ensure that energy consumption can be reduced while maintaining normal driving. At this time, compared with directly turning off the tunnel lights 31, keeping the tunnel lights 31 at the minimum standard illumination can provide basic lighting for the vehicle on the one hand, and on the other hand, avoid damage to the lights caused by frequent switching on and off of the tunnel lights 31, thereby increasing the service life.

[0025] Re-reference Figure 1-Figure 4Preferably, the tunnel lighting lamp 31 is inclined at an angle of 20° to 30° from perpendicular to the ground to the direction of vehicle travel. It is understandable that the light source direction of the tunnel lighting lamp 31 is in the same direction as the direction of vehicle travel. On the one hand, it can effectively prevent the tunnel lighting lamp 31 from directly shining into the driver's eyes, thereby affecting driving and improving safety. On the other hand, compared with vertical illumination of the ground, the inclined lighting of the tunnel lighting lamp 31 can improve the utilization rate of the light source and avoid the situation where the light source is reflected by the ground to form ground reflection, thereby further improving safety.

[0026] Re-reference Figure 1Preferably, the lighting system 3 also includes a plurality of shed road lighting lamps 32, which are all connected to the energy storage system 4 and the control terminal 5. The plurality of shed road lighting lamps 32 are arranged in the solar light-shielding shed road 2 along the length direction of the solar light-shielding shed road 2. When the solar light-shielding shed road 2 performs natural light shading on the vehicles entering, the light intensity of the solar light-shielding shed road 2 is adjusted synchronously by the shed road lighting lamps 32. In specific applications, the shed road lighting lamps 32 use COB-LED tunnel lights, and only one row is arranged, which are located on the top wall of the solar light-shielding shed road 2. When encountering weak light intensity such as rainy days and evenings, when the vehicle is driving outside the tunnel, there is still a certain amount of light, and the headlights of the vehicle may not be turned on at this time. When entering the solar light-shielding shed road 2, after being shaded by the solar light-shielding shed road 2, the light intensity of the solar light-shielding shed road 2 will be lower, which may easily cause the driver to suddenly fall into a short period of darkness, affecting the driver's driving. By setting the shed road lighting lamp 32, it is possible to provide basic brightness for the solar shading shed road 2 at this time, and cooperate with the tunnel lighting lamp 31 in the tunnel body 1 to dim the light, so that the light environment before and after the vehicle enters the tunnel remains relatively stable, and the driving comfort and safety are improved. Specifically, during the day when the light intensity outside the tunnel body 1 is sufficient, along the length direction of the solar shading shed road 2, the light intensity inside the solar shading shed road 2 gradually decreases from near the outside of the tunnel body 1 to the inside of the tunnel body 1. If the driver can gradually reduce the original strong light intensity outside the tunnel body 1 to the weak light intensity inside the tunnel body 1, the driving comfort and safety can be improved. At this time, the shed road lighting lamp 32 can be turned off to save energy. At night when the light intensity outside the tunnel body 1 is low, the light intensity inside the solar shading shed road 2 gradually increases from near the outside of the tunnel body 1 to the inside of the tunnel body 1, and at this time, the shed road lighting lamp 32 and the tunnel lighting lamp 31 can reduce the power to provide basic light, saving energy. Furthermore, a plurality of light intensity sensors are provided in the solar shading shed 2, and the plurality of light intensity sensors are respectively connected to the energy storage system 4 and the control terminal 5. When the light intensity sensor senses that the light intensity in the solar shading shed 2 is higher than the minimum standard illumination, the control terminal 5 controls the shed lighting 32 to turn off to save energy. When the light intensity sensor senses that the light intensity in the solar shading shed 2 is lower than the minimum standard illumination, the control terminal 5 controls the shed lighting 32 to turn on and maintain the minimum standard illumination. It should be noted that, unlike the tunnel lighting 31, since the light intensity in the solar shading shed 2 is greater than the minimum standard illumination most of the time, the shed lighting 32 is turned off most of the time to save energy, and is only turned on at night or in extreme weather conditions to maintain the minimum standard illumination. The minimum standard illumination is based on the country's minimum standard for tunnel lighting brightness, and of course it can be adjusted accordingly according to actual needs.

[0027] Preferably, the blocking density of the solar shading shed 2 gradually increases from the end of the solar shading shed 2 far away from the tunnel body 1 to the end of the solar shading shed 2 close to the tunnel body 1. In specific applications, a solar panel is laid on the top of the solar shading shed 2, and the solar panel is conical. The conical setting is conducive to inclined light chasing, and can allow rain and snow to slide naturally from the solar panel, reduce manual cleaning, and improve the power generation effect. Taking the solar shading shed 2 at the entrance of the tunnel body 1 as an example, the blocking density is low at the position far away from the tunnel body 1, that is, the light intensity here is close to the light intensity outside the tunnel body 1. As it approaches the entrance of the tunnel body 1, the blocking density of the solar shading shed 2 gradually increases, that is, the closer the position is to the tunnel body 1, the weaker the blocking of sunlight will be, thereby gradually increasing the light intensity of the solar shading shed 2, so that the driver can drive in the solar shading shed 2 with gradually reduced light intensity, thereby improving driving comfort and safety. The blocking density can be adjusted by setting light-blocking sheds and light-blocking walls with different blocking degrees. The direction of change of the blocking density of the solar light-blocking shed 2 at the exit of the tunnel body 1 is opposite to that at the entrance, which will not be repeated here. Furthermore, the solar light-blocking shed 2 is provided with a plurality of shading windows connected to the control terminal 5. By opening the shading windows, more sunlight can enter the solar light-blocking shed 2, thereby increasing the light intensity in the solar light-blocking shed 2. By closing the shading windows, the light intensity in the solar light-blocking shed 2 can be reduced. Compared with the dimming of the shed lighting 32, it can further reduce energy consumption. Moreover, for some extreme situations, such as rainy weather or sunny days with excessive light, the blocking density of the solar light-blocking shed 2 can be adjusted accordingly by closing and opening the shading windows, thereby achieving the effect of gradually changing the blocking density. In addition, in most cases, closing and opening the shading windows is sufficient to adjust the light intensity of the solar shading shed 2. However, when the light intensity outside the tunnel is too strong or too low, the shed lighting 32 can be used to supplement the light intensity of the solar shading shed 2, so that the light intensity of the solar shading shed 2 will not be much different from that outside the tunnel and inside the tunnel body 1. The solar shading shed 2 allows the driver to gradually transition from the original stronger light intensity outside the tunnel to the weaker light intensity inside the tunnel body 1, and can also greatly reduce the power required by the tunnel lighting 31 in the tunnel body 1.

[0028] Refer to Figure 5 , Figure 5It is a hardware connection diagram of the solar zero-carbon tunnel in the embodiment. Preferably, the solar zero-carbon tunnel also includes a monitoring center 6 and a communication center 7. The monitoring center 6 and the communication center 7 are connected by signal, and the communication center 7 is connected by signal with the control terminal 5. In specific application, each tunnel lighting lamp 31 and the shed road lighting lamp 32 are provided with a wireless grid communication module. The number of communication centers 7 is two. The two communication centers 7 are respectively arranged at the tunnel entrances at both ends of the tunnel body 1, and function through the energy storage system 4. At the same time, the two communication centers 7 are networked with the wireless grid communication modules on multiple lighting lamps. The monitoring center 6 is respectively connected by signal with the communication center 7 and the wireless grid communication module, so that the current, voltage, power, whether the fault and other data of the lighting lamp can be obtained in real time. The monitoring center 6 includes a plurality of light intensity detectors, and the plurality of light intensity detectors are evenly distributed in the tunnel body 1 and the solar shading shed road 2 along the length direction of the tunnel body 1 to monitor the light intensity of the tunnel body 1 and the solar shading shed road 2. The monitoring center 6 transmits the light intensity information of the tunnel body 1 and the solar shading shed 2 to the communication center 7. The communication center 7 receives and analyzes the light intensity information to obtain dimming parameters. The communication center 7 transmits the dimming parameters to the control terminal 5. The control terminal 5 controls and adjusts the power of the tunnel lighting 31 according to the dimming parameters to change its brightness to achieve dimming in the tunnel body 1. Furthermore, the monitoring center 6 can also divide a day into five dimming periods according to the geographical location of the tunnel body 1, the season and climate at that time, the time of dusk and dawn, the power adjustment of the recent tunnel lighting lamp 31 and other information, and analyze the changes in the light intensity outside the tunnel body 1 in recent time: a night without light period, a weak light period in the early morning, a normal light period during the day, a strong light period in the afternoon and a weak light period in the evening. In this way, the light intensity outside the tunnel body 1 in each dimming period is nearly equal, that is, the power of the tunnel lighting lamp 31 is kept unchanged in the same dimming period, thereby extending the service life of the tunnel lighting lamp 31. There is no need to monitor the light intensity outside the tunnel body 1 in real time through the monitoring center 6, thereby reducing energy consumption. Of course, when the monitoring center 6 detects that the weather has changed drastically, it will actively monitor the light intensity outside the tunnel body 1 and control the control terminal 5 to dim accordingly.

[0029] Re-reference Figure 5Preferably, the communication center 7, the monitoring center 6, the lighting system 3, the energy storage system 4 and the control terminal 5 are interconnected to form a local area network. In specific applications, the communication center 7, the monitoring center 6, the lighting system 3, the energy storage system 4, the control terminal 5 and the wireless grid communication module are networked based on the wireless grid network to form a local area network. Since most tunnels are built in places with poor signals such as mountains and the wild, by forming a wireless local area network, there is no need to set up dedicated routing nodes, and the communication can be automatically networked without power-on. It supports automatic networking and automatic recovery networking. In places with poor signals, it will not affect the dimming work and internal information transmission of the solar zero-carbon tunnel, ensuring the normal operation of the dimming function, improving stability, and broadening application scenarios. At the same time, multiple wireless grid communication modules are equivalent to wireless multi-level relay communications, so that the relay coverage of the tunnel body 1 can reach up to 10KM at most, ensuring the stability of signal transmission. Specifically, the length of the solar shading shed 2 is determined according to the total power supply of the solar zero-carbon tunnel, that is, the total amount of electric energy required by the communication center 7, the monitoring center 6, the lighting system 3 and the control terminal 5 in the solar zero-carbon tunnel is calculated, and the length of the required solar panel is calculated according to the required total amount of electric energy, thereby setting up a solar shading shed 2 of corresponding length, so as to ensure that all electricity in the solar zero-carbon tunnel is obtained by solar power generation through the solar shading shed 2, and achieve zero-carbon environmental protection. Of course, in other embodiments, in some areas with high light intensity, due to the high light intensity outside, if the solar shading shed 2 is short, the time for the large external light intensity to decrease to the weaker light intensity inside the tunnel will be short, resulting in a too fast decrease in light intensity. At this time, the length of the solar shading shed 2 can be lengthened to extend the time for the solar shading shed 2 to perform shading and dimming, so that the light intensity gradually decreases to the same level as that inside the tunnel when entering the tunnel, and gradually increases to the same level as that outside the tunnel when exiting the tunnel, thereby improving driving comfort and safety. Furthermore, the solar zero-carbon tunnel also includes an energy supply system, which is electrically connected to the energy storage system 4, and the energy supply system is connected to the mains. That is to say, under normal circumstances, the electricity generated by the solar panels on the solar shade shed 2 through solar power generation is stored in the energy storage system 4, which can fully meet all the electricity required by the solar zero-carbon tunnel. However, when encountering continuous long-term bad weather, such as long-term rainy weather, the power generation of the solar shade shed 2 is not enough to maintain the energy supply of the entire tunnel. The energy supply system can replenish the energy storage system 4 through external mains, that is, the energy supply system is equivalent to a backup power supply, which is used to deal with the situation where the energy storage system 4 has insufficient energy storage, thereby improving the stability of the operation of the solar zero-carbon tunnel.In addition, this embodiment can be modified based on the existing tunnels that use AC power to broaden the application scenarios and reduce the cost of improving the existing tunnels. Specifically, a communication center 7, a monitoring center 6, a lighting system 3, an energy storage system 4 and a control terminal 5 are set up in the existing tunnel, the energy storage system 4 is connected to the AC power, and power is mainly supplied by the energy storage system 4. In addition, solar shading sheds 2 can be set up at the tunnel entrances at both ends of the tunnel according to needs.

[0030] Re-reference Figure 5 Preferably, the solar zero-carbon tunnel also includes a remote control terminal 8, and the remote control terminal 8 is connected to the communication center 7 by signal. In specific applications, the remote control terminal 8 is a mobile phone, a computer or other device, and the communication center 7 is provided with a 4G wireless gateway, through which the communication center 7 is connected to the remote control terminal 8 by signal, and the current, voltage, power, fault, light intensity information of the tunnel body 1 and the solar shading shed 2, the daily power consumption and total power consumption of the lighting system 3, the remaining power of the energy storage system 4 and other data are transmitted to the remote control terminal 8, and the current, voltage, power, fault, light intensity information of the tunnel body 1 and the solar shading shed 2, the daily power consumption and total power consumption of the lighting system 3, the remaining power of the energy storage system 4 and other data of the lighting can be viewed in real time through the remote control terminal 8, and the remote control terminal 8 can also remotely control the control terminal 5 through the communication center 7 to change the power of the tunnel lighting 31, thereby remotely controlling the light intensity in the tunnel body 1.

[0031] Re-reference Figure 1 Preferably, along the length direction of the tunnel main body 1, the tunnel main body 1 is divided into a plurality of dimming areas. In specific application, the present embodiment includes six dimming areas, which are the first entrance area, the second entrance area, the transition area, the middle area, the second exit area and the first exit area in the direction of vehicle travel. When the light intensity is high during the day, after dimming the tunnel lighting lamps 31 and the shed road lighting lamps 32, the light intensity in the middle area is the lowest, and the light intensity of the area closer to the outside of the tunnel main body 1 gradually increases. In this way, the progressive segmented dimming method can, on the one hand, allow the driver to gradually adapt to the changes in light intensity inside and outside the tunnel, improve driving comfort and safety, and on the other hand, reduce the power of the tunnel lighting lamps 31 as much as possible and reduce energy consumption while ensuring safety. When the light intensity is low at night, the power of the tunnel lighting lamps 31 and the shed road lighting lamps 32 can be further reduced to maintain the basic brightness, which is close to the light intensity outside the tunnel.

At this time, the power of the COB-LED tunnel lights is 30W. The length of the second exit area is 33m, the design illumination is 122cd / ㎡, and there are 11 COB-LED tunnel lights with an interval of 3m. At this time, the power of the COB-LED tunnel lights is 60W. The length of the first exit area is 33m, the design illumination is 176cd / ㎡, and there are 11 COB-LED tunnel lights with an interval of 3m. At this time, the power of the COB-LED tunnel lights is 80W.

[0033] Comparative Example 1: In this comparative example, the main body of the tunnel 1 adopts cement concrete pavement, the length of the main body of the tunnel 1 is 303m, the width of the tunnel pavement is 11m, the height of the tunnel section is 7.8m, the design speed is 80km / h, the design hourly traffic volume is 750veh / (h·In), and the coefficient between the average brightness and the average illumination is 10lx / (cd / ㎡). Among them, the external brightness of the tunnel in this comparative example is 3000cd / ㎡, the length of the first entrance area is 42m, the design illumination is 955cd / ㎡, and 20 high-pressure sodium lamps are set at an interval of 4.2m. At this time, the power of the high-pressure sodium lamp is 400W. The length of the second entrance area is 39m, the design illumination is 488cd / ㎡, and 16 high-pressure sodium lamps are set at an interval of 5.2m. At this time, the power of the high-pressure sodium lamp is 250W. The length of the transition area is 72m, the design illumination is 133cd / ㎡, and 24 high-pressure sodium lamps are set at an interval of 6m. At this time, the power of the high-pressure sodium lamp is 100W. The length of the middle area is 84m, the design illumination is 36cd / ㎡, and there are 28 high-pressure sodium lamps with an interval of 6m. The power of the high-pressure sodium lamp is 100W. The length of the second exit area is 33m, the design illumination is 122cd / ㎡, and there are 8 high-pressure sodium lamps with an interval of 8m. The power of the high-pressure sodium lamp is 100W. The length of the first exit area is 33m, the design illumination is 176cd / ㎡, and there are 14 high-pressure sodium lamps with an interval of 5m. The power of the high-pressure sodium lamp is 100W. The high-pressure sodium lamps in this comparative example are divided into two rows and are arranged on both sides of the top of the tunnel body 1 in a symmetrical manner.

[0034] The power consumption comparison results between Example 2 and Comparative Example 1 are shown in Table 1.

[0035]

[0036] Table 1 From the data in Table 1, it can be seen that, in the case of the same tunnel external brightness of 3000cd / ㎡, in order to make multiple dimming areas reach the preset illumination standard, in Example 2, only one row of COB-LED tunnel lights is set on the top of the tunnel body 1. Compared with the traditional method of symmetrically arranging lights on both sides of high-pressure sodium lamps, the power of a single lamp in Example 2 is less than that of Comparative Example 1, avoiding the impact of a single lamp power directly shining on the driver's eyes and making the light softer. At the same time, in Example 2, only one row of lamps is set on the top of the tunnel, so the number of lamps can be increased to reduce the distance between adjacent lamps, so that the light distribution in the tunnel is more uniform. In addition, the overall power of Example 2 is 40% more energy-saving than that of Comparative Example 1. That is to say, compared with Comparative Example 1, Example 2 can reduce 40% of energy consumption to achieve the preset illumination standard, so that the energy storage system 4 can supply energy to the tunnel only through solar power generation, without additional power supply, to achieve energy saving, low carbon and environmental protection.

[0037] Embodiment three: Reference Figure 6 , Figure 6 The flowchart of the smart dimming method based on the solar zero-carbon tunnel in the embodiment is as follows. The smart dimming method based on the solar zero-carbon tunnel in the embodiment is based on the solar zero-carbon tunnel in the first embodiment, and includes the following steps: S1: The control terminal 5 obtains the light intensity outside the tunnel body 1 and at the tunnel entrance of the tunnel body 1. In specific applications, the monitoring center 6 obtains the light intensity outside the tunnel body 1 and at the tunnel entrance of the tunnel body 1, respectively, and transmits the light intensity information to the communication center 7. The communication center 7 receives and analyzes the light intensity information to obtain the dimming parameters. The communication center 7 transmits the dimming parameters and the light intensity information outside the tunnel body 1 and at the tunnel entrance of the tunnel body 1 to the control terminal 5.

[0038] Preferably, the monitoring center 6 also obtains the geographical location information and seasonal information of the tunnel body 1, and divides a day into five dimming periods according to the geographical location information, seasonal information and the changes in the light intensity outside the tunnel body 1 in recent time: a night without light period, a weak light period in the early morning, a normal light period during the day, a strong light period in the afternoon and a weak light period in the evening. The power of the tunnel lighting 31 can be kept unchanged within the same dimming period. Of course, when the monitoring center 6 detects a drastic change in the weather, it will actively monitor the light intensity outside the tunnel body 1 and control the control terminal 5 to dim accordingly.

[0039] Preferably, the communication center 7, the monitoring center 6, the lighting system 3, the energy storage system 4 and the control terminal 5 are interconnected to form a local area network. In this way, there is no need to set up a dedicated routing node, and the communication can be automatically networked without power-on. It supports automatic networking and automatic recovery networking. In places with poor signals, it will not affect the dimming work and internal information transmission of the solar zero-carbon tunnel, ensuring the normal operation of the dimming function, improving stability, and broadening the application scenarios.

[0040] S2: The control terminal 5 controls the lighting system 3 to dim according to the dimming parameters, so that the light intensity at the tunnel entrance of the tunnel body 1 is between the light intensity outside the tunnel body 1 and the light intensity inside the tunnel body 1 .

[0041] Preferably, the tunnel body 1 is divided into six dimming areas along the length direction of the tunnel body 1, which are the first entrance area, the second entrance area, the transition area, the middle area, the second exit area and the first exit area in the direction of vehicle travel. The control terminal 5 controls the lighting system 3 to adjust the light intensity of the multiple dimming areas separately, so that the light intensity of the dimming area near the tunnel entrance of the tunnel body 1 is greater than the light intensity of the dimming area in the middle of the tunnel body 1. In the case of high light intensity during the day, after dimming the tunnel lighting lamp 31 and the shed road lighting lamp 32, the light intensity of the middle area is the lowest, and the light intensity of the area closer to the outside of the tunnel body 1 gradually increases. In this way, the progressive segmented dimming method can, on the one hand, allow the driver to gradually adapt to the changes in light intensity inside and outside the tunnel, improve driving comfort and safety, and on the other hand, reduce the power of the tunnel lighting lamp 31 as much as possible and reduce energy consumption while ensuring safety. In the case of low light intensity at night, the power of the tunnel lighting lamp 31 and the shed road lighting lamp 32 can be further reduced to maintain the basic brightness, which is close to the light intensity outside the tunnel.

[0042] Preferably, the lighting system 3 includes a plurality of tunnel lighting lamps 31, which are arranged at the top of the tunnel body 1 along the length direction of the tunnel body 1, and the tunnel lighting lamps 31 are inclined to illuminate the direction of vehicle travel perpendicular to the ground, and the angle of the inclined lighting is 20°~30°.

[0043] S3: When the solar shading shed 2 is shading the vehicles entering, the light intensity of the solar shading shed 2 is adjusted synchronously through the shed lighting 32. In specific applications, the shed lighting 32 adopts COB-LED tunnel lights, and only one row is set, located on the top wall of the solar shading shed 2. When encountering the situation of weak light intensity such as rainy days and evenings, the headlights of the vehicles may not be turned on when the vehicles are driving outside the tunnel because there is still a certain amount of light. When entering the solar shading shed 2, after being shaded by the solar shading shed 2, the light intensity of the solar shading shed 2 will be lower, which may easily cause the driver to suddenly fall into a short darkness and affect the driver's driving. And through the setting of the shed lighting 32, it can provide basic brightness for the solar shading shed 2 at this time, and cooperate with the tunnel lighting 31 in the tunnel body 1 to adjust the light, so that the light environment before and after the vehicle enters the tunnel remains relatively stable, improving the driving comfort and safety.

[0044] Preferably, along the length direction of the solar shading shed 2, the light intensity in the solar shading shed 2 gradually decreases from the area close to the outside of the tunnel body 1 to the area inside the tunnel body 1. If the driver can gradually reduce the light intensity from the original strong light intensity outside the tunnel body 1 to the weak light intensity inside the tunnel body 1, the driving comfort and safety will be improved. Furthermore, the solar shading shed 2 is provided with a plurality of shading windows connected to the control terminal 5. By opening the shading windows, more sunlight can enter the solar shading shed 2, thereby improving the light intensity in the solar shading shed 2. By closing the shading windows, the light intensity in the solar shading shed 2 is reduced, which can further reduce energy consumption compared to the dimming of the shed lighting 32.

[0045] S4: The communication center 7 transmits the dimming parameters, light intensity information, and the working status information of the lighting system 3 and the energy storage system 4 to the remote control terminal 8. The remote control terminal 8 receives the information and can remotely control the control terminal 5 through the communication center 7 to dim the lighting system 3. In specific applications, the remote control terminal 8 is a mobile phone, computer or other device, and the communication center 7 is provided with a 4G wireless gateway. The communication center 7 is connected to the remote control terminal 8 by signal through the 4G wireless gateway, and the current, voltage, power, fault, light intensity information of the tunnel body 1 and the solar shading shed 2, the daily power consumption and total power consumption of the lighting system 3, the remaining power of the energy storage system 4 and other data are transmitted to the remote control terminal 8. Through the remote control terminal 8, the current, voltage, power, fault, light intensity information of the tunnel body 1 and the solar shading shed 2, the daily power consumption and total power consumption of the lighting system 3, the remaining power of the energy storage system 4 and other data can be viewed in real time. In addition, the remote control terminal 8 can also remotely control the control terminal 5 through the communication center 7 to change the power of the tunnel lighting 31, thereby remotely controlling the light intensity in the tunnel body 1.

[0046] In summary, by setting up the solar shading shed 2, before the vehicle enters the tunnel body 1, the solar shading shed 2 can block the sunlight at the tunnel entrance of the tunnel body 1, which is equivalent to the first dimming of the light intensity, so that the light intensity inside the solar shading shed 2 is slightly lower than the light intensity outside the tunnel body 1, avoiding the driver from having a "momentary visual blind spot" due to the large difference in light intensity inside and outside the tunnel. When the vehicle then enters the tunnel body 1 from the solar shading shed 2, the control terminal 5 controls the lighting system 3 to adjust the light intensity of the inner area of ​​the tunnel body 1, which is equivalent to the second dimming of the light intensity, so that the light intensity of the inner area of ​​the tunnel body 1 is slightly lower than the light intensity of the solar shading shed 2, allowing the driver to enter the tunnel with the light intensity gradually reduced, so that the driver's eyes can gradually adapt to the light intensity of the inner area of ​​the tunnel body 1. At the same time, solar panels are laid outside the solar shading shed 2. The solar panels can generate solar power and store the electricity in the energy storage system 4. The lighting system 3 and the control terminal 5 can be operated by the electricity in the energy storage system 4, without the need to supply additional power to the tunnel, which is more energy-saving and environmentally friendly. In addition, the solar shading shed 2 shades the sunlight once, which is equivalent to setting up a light buffer channel, so that the light intensity in the tunnel body 1 can be reduced accordingly. There is no need to set up a high-power lighting system 3 to make the light intensity in the tunnel body 1 as close as possible to the light intensity outside the tunnel body 1. It only needs to be close to the light intensity of the solar shading shed 2, thereby saving power consumption and avoiding high-power light directly hitting the driver's eyes and affecting driving.

For those skilled in the art, the present application may have various changes and variations.
