Description

Technical Field

[0001] The present invention relates to the field of tunnel detection technology, and in particular to an ultra-long tunnel intelligent linkage system and method. Background Art

[0002] With the development of emerging technologies such as 5G, Internet of Things, big data, and artificial intelligence, my country has launched a new generation of smart highway demonstration projects, promoted the upgrade and iteration of traditional infrastructure systems in traffic tunnels, and tunnel operation and management has entered a new stage of development of informatization, digitization, and intelligence, enabling intelligent construction, daily operation and maintenance, and safety management of tunnels. However, super-long highway tunnels are much longer than ordinary tunnels, such as 10 kilometers or 20 kilometers. Once a fire occurs in a super-long highway tunnel, it will cause damage to vehicles and traffic congestion at the least, and even affect the life safety of drivers and passengers at the worst. There are also two major outstanding problems in the construction of smart highway tunnels. First, the interpretation of the concept of intelligence is not clear and definite enough, and the concepts of intelligence, intelligence, and informatization are confused, making it difficult to form a unified construction goal; second, there is a lack of unified evaluation standards for the intelligence of highway tunnels, making it difficult to objectively evaluate the intelligence level of tunnel projects and scientifically guide the design and construction of smart tunnel projects. Smart tunnels are not equivalent to intelligent tunnels or digital tunnels. They are a more advanced form of intelligent tunnels, which puts higher requirements on the construction of tunnel projects.

[0003] In the prior art, the tunnel disaster prevention and rescue emergency plan is mainly stored in text form, with a low degree of digitization. In the process of emergency response, the response personnel match the emergency situation based on the text emergency plan. This matching process takes a certain amount of time, which makes the emergency response not timely enough. Since the emergency situations considered by the paper emergency plan are limited, when the match with the actual situation is not high, the emergency response made according to the emergency plan is not accurate enough. In addition, there may be cases where some emergency personnel have memory errors and cause handling errors, resulting in insufficient accuracy of the overall emergency response. Since the emergency response personnel communicate through walkie-talkies, the communication method is limited and the communication efficiency is low. The response personnel do not have enough understanding of the overall situation on the scene, and the emergency commanders also find it difficult to obtain on-site information in a timely and comprehensive manner, so the emergency decisions made may not be accurate enough.

[0004] Therefore, it is urgent to propose an intelligent linkage system and method for ultra-long tunnels to solve the technical problems in the existing technology that when a disaster occurs in an ultra-long tunnel, information transmission and processing are performed by personnel, resulting in insufficient accuracy of the overall emergency response, and emergency commanders find it difficult to obtain on-site information in a timely and comprehensive manner, thus leading to inaccurate emergency decision-making. Summary of the invention

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0019] like Figure 1 As shown, a specific embodiment of the present invention discloses an ultra-long tunnel intelligent linkage system 100, including: The monitoring system 101 is used to monitor vehicles in the super-long tunnel. When an abnormal vehicle exceeding a temperature threshold is detected, a temperature abnormality warning signal is sent and the abnormal vehicle is tracked and located. When the abnormal vehicle catches fire, an automatic fire extinguishing zone is determined according to the location information of the abnormal vehicle, and an initial fire alarm signal is sent. When the abnormal vehicle stops driving in the automatic fire extinguishing zone, the initial fire alarm signal is updated and an updated target fire alarm signal is sent. The guidance system 102 is used to guide abnormal vehicles to the automatic fire extinguishing area when receiving the initial fire alarm signal, and to remind vehicles in the extra-long tunnel; The sprinkler system 103 is used to control the automatic fire extinguishing area to perform preparation work when receiving the initial fire alarm signal, and to extinguish the fire of abnormal vehicles in the automatic fire extinguishing area when receiving the target fire alarm signal; The smoke suppression system 104 is used to control the smoke suppression device within the preset range of the automatic fire extinguishing area to perform preparatory work when an initial fire alarm signal is received, and to start the smoke suppression device when a target fire alarm signal is received, and to suppress the degree of smoke generated during an abnormal vehicle fire according to the smoke suppression device.

[0020] It should be understood that the construction of smart tunnels should be fully understood and expressed around the four aspects of resilience, intelligence, greenness, and humanity. The connotation of resilience is self-cognition and adjustment, the ability to perceive, adapt, and change the environment, which is specifically reflected in safety, durability, and recoverability; the connotation of intelligence is knowledge accumulation, acquisition of new knowledge and innovation, problem-solving thinking and practice, which is manifested in the acquisition, processing, analysis, expression, decision-making, and innovation potential of information in highway tunnels, and is a kind of intelligent construction and operation and maintenance; the connotation of greenness is moral constraints and good life, the balance and prosperity of social interests, and requires the goals of energy saving, water saving, material saving, land saving, and environmental protection in tunnel construction and operation and maintenance; the philosophical connotation of humanity is communication with people, the balance of social interests, and the pursuit of prosperity. In engineering construction, it is required to be people-oriented and fully reflect aesthetic value, cultural connotation, and social contribution.

[0021] Combining the four core elements of smart tunnels, namely "resilience, intelligence, greenness and humanity", at the current stage, combined with the design and construction progress of Shengli Tunnel, the projects that can be optimized and improved in smart quality construction are mainly reflected in tunnel monitoring, fire protection, lighting, painting, traffic safety, ventilation, disaster prevention and new energy.

[0022] In a specific embodiment of the present invention, the intelligent linkage system of a smart tunnel (i.e., an ultra-long tunnel) may include a monitoring system, a guidance system, a sprinkler system, and a smoke suppression system, so as to provide all-round protection for the ultra-long tunnel. The ultra-long tunnel may be a tunnel that exceeds the length of an ordinary tunnel. For example, taking a certain tunnel as an example, it may be a tunnel with a total length of approximately 20,000 meters. The temperature information of all vehicles in the super-long tunnel can be obtained, and then the temperature information of all vehicles can be checked one by one, so that the vehicles can be detected in the early stage of the fire. Specifically: the monitoring system can detect the vehicles in the super-long tunnel. When an abnormal vehicle exceeding the temperature threshold is detected, a temperature abnormality warning signal can be sent to other systems and the abnormal vehicle can be tracked and located. When the abnormal vehicle catches fire, the automatic fire extinguishing area can be determined according to the location information of the abnormal vehicle, and an initial fire alarm signal can be sent to other systems. The abnormal vehicle can be guided to the automatic fire extinguishing area through the guidance system, and the vehicles in the super-long tunnel can be reminded. When the abnormal vehicle stops driving in the automatic fire extinguishing area, the initial fire alarm signal can be updated, and then the initial fire alarm signal can be updated, and the updated target fire alarm signal can be sent, wherein the temperature abnormality warning signal, the initial fire alarm signal and the target fire alarm signal are all updated in real time, so that the latest information of the abnormal vehicle can be obtained. The specific temperature threshold can be set according to the actual situation, and the embodiment of the present invention is not limited here. The guidance system may include tunnel broadcasting, laser projection, information boards, signs, etc.; other systems include but are not limited to guidance systems, sprinkler systems and smoke suppression systems. When the sprinkler system receives an initial fire alarm signal, it can control the automatic fire extinguishing area to perform preparatory work. When the sprinkler system receives a target fire alarm signal, it can extinguish the abnormal vehicle according to the automatic fire extinguishing area. The sprinkler system may be a tunnel fine water mist sprinkler system. The smoke suppression system may include a tunnel-specific smoke and haze suppression air purifier. When the smoke suppression system receives an initial fire alarm signal, it controls the smoke suppression device within a preset range of the automatic fire extinguishing area to perform preparatory work. When the target fire alarm signal is received, the smoke suppression device, i.e., the tunnel-specific smoke and haze suppression air purifier, is started, so that the degree of smoke generated during the fire of the abnormal vehicle can be suppressed according to the smoke suppression device. When the target fire alarm signal is received, the smoke suppression device can be started according to the automatic fire extinguishing area, and the smoke generated during the fire of the abnormal vehicle can be suppressed according to the smoke suppression device. The preset range may be a certain range around the automatic fire extinguishing area, which can be set specifically according to actual conditions.

[0023] Compared with the existing technology, the monitoring system is used to monitor vehicles in super-long tunnels. When an abnormal vehicle exceeding the temperature threshold is detected, a temperature abnormality warning signal is sent and the abnormal vehicle is tracked and located. When an abnormal vehicle catches fire, the automatic fire extinguishing zone is determined according to the location information of the abnormal vehicle, and the abnormal vehicle is guided to the automatic fire extinguishing zone through the guidance system, and an initial fire alarm signal is sent. When the abnormal vehicle stops in the automatic fire extinguishing zone, the initial fire alarm signal is updated and an updated target fire alarm signal is sent; the guidance system is used to guide the abnormal vehicle to the automatic fire extinguishing zone and remind the vehicles in the super-long tunnel; the sprinkler system is used to receive When an initial fire alarm signal is received, the automatic fire extinguishing area is controlled to perform preparatory work; when a target fire alarm signal is received, the abnormal vehicles in the automatic fire extinguishing area are extinguished; the smoke suppression system is used to control the smoke suppression device within a preset range of the automatic fire extinguishing area to perform preparatory work when an initial fire alarm signal is received; when a target fire alarm signal is received, the smoke suppression device is started, and the degree of smoke generated during the fire of the abnormal vehicle is suppressed according to the smoke suppression device; the present invention realizes the intelligent linkage of super-long tunnels through the super-long tunnel intelligent linkage system, so that when a disaster occurs in the super-long tunnel, the super-long tunnel can be predicted and processed through the intelligent linkage system.

[0024] In some embodiments of the present invention, Figure 2 As shown, the monitoring system 101 includes a dual-wavelength flame detection system 1011, a multi-spectrum flame detection system 1012 and a fiber grating temperature sensing system 1013; The fiber Bragg grating temperature sensing system 1013 is used to detect whether there are abnormal vehicles exceeding the temperature threshold in the super-long tunnel, and to track and locate the abnormal vehicles; The multi-spectral flame detection system 1012 is used to detect whether an abnormal vehicle is on fire during driving; The dual-wavelength flame detection system 1011 is used to detect whether an abnormal vehicle has stopped running.

[0025] In a specific embodiment of the present invention, a dual-wavelength flame detection system, a multi-spectral flame detection system and a fiber Bragg grating temperature sensing system can be provided in an ultra-long tunnel, wherein the fiber Bragg grating temperature sensing system can detect moving vehicles, thereby detecting the temperature of the vehicles, obtaining the temperature information of the vehicles, and further detecting whether there are abnormal vehicles exceeding the temperature threshold in the ultra-long tunnel, and can also track and locate the abnormal vehicles. If so, the abnormal vehicles can be monitored by the multi-spectral flame detection system. The multi-spectral flame detection system can detect mobile fire sources, thereby detecting whether the abnormal vehicles are on fire during driving. If so, the dual-wavelength flame detection system can be used for monitoring to detect whether the abnormal vehicles have stopped driving. The tunnel monitoring system of the fixed fire detection technology of the dual-wavelength flame detection system detects the fire when the vehicle stops moving, and the tunnel monitoring system of the mobile fire detection technology of the multi-spectral flame detection system detects the fire when the vehicle is moving. Compared with the detection and alarm after the burning vehicle stops moving, the mobile fire detection technology can detect the fire earlier than the monitoring system of the fixed fire detection technology, which can buy more time for emergency rescue of tunnel fires and improve the disaster prevention and mitigation capabilities of the tunnel. Fiber Bragg grating sensing technology has a smaller grating spacing (10m for traditional technology and 1m for 2.0 technology), a faster response speed, and can accurately detect and alarm in the early stages of a fire. Fiber Bragg grating sensing technology has a longer detection distance, which can greatly save the amount of transmission optical cables, reduce additional construction, and save investment costs; it can significantly reduce the number of fusion points, thereby reducing potential fault points and making later maintenance simpler.

[0026] In some embodiments of the present invention, the fiber Bragg grating temperature sensing system 1013 is also used to obtain temperature information of all vehicles in the ultra-long tunnel, and perform temperature anomaly detection on the temperature information of each vehicle to obtain an initial detection result.

[0027] In a specific embodiment of the present invention, the temperature information of all vehicles in an ultra-long tunnel can be obtained, and then the temperature anomaly detection can be performed on the temperature information of each vehicle one by one to determine whether there are vehicles exceeding the temperature threshold, that is, to obtain the initial detection result, thereby achieving the purpose of rapid detection in the early stage of a vehicle fire.

[0028] In some embodiments of the present invention, the fiber Bragg grating temperature sensing system 1013 is also used to analyze the monitoring data of the ultra-long tunnel according to the location and time of the abnormality detection to identify the abnormal vehicle when the initial detection results include vehicles exceeding the temperature threshold.

[0029] In a specific embodiment of the present invention, when there is a vehicle exceeding the temperature threshold in the initial detection results, the location and time of the abnormal vehicle detection can be determined based on the fiber optic Bragg grating temperature sensing system, so that the monitoring data of the ultra-long tunnel monitoring camera can be analyzed and processed, and the abnormal vehicle that passed by when the abnormal location and time were detected can be obtained.

[0030] In some embodiments of the present invention, the monitoring system 101 is also used to perform position prediction based on the positioning system of the abnormal vehicle to determine the predicted fire location; The sprinkler system 103 and the smoke suppression system 104 are also used to determine the automatic fire extinguishing zone according to the predicted fire location when receiving the abnormal temperature warning signal.

[0031] In a specific embodiment of the present invention, after the abnormal vehicle is determined, the navigation information of the vehicle can be obtained based on the GPS positioning system of the abnormal vehicle, so that the driving direction and position of the positioning system can be predicted, and the approximate predicted fire location can be determined, so that the sprinkler system 103 and the smoke suppression system 104 can determine the automatic fire extinguishing area according to the predicted fire location when receiving the temperature abnormality warning signal.

[0032] According to incomplete statistics, when a traffic accident occurs in a tunnel, the incidence of secondary accidents exceeds 54%, and the property losses and casualties caused by secondary accidents account for more than 70% of the total losses. It can be seen that secondary accidents have seriously expanded the impact and losses of traffic accidents in tunnels. The reason for secondary accidents in tunnels, in addition to the special structure of the tunnel that easily causes other secondary disasters and accidents, a more important reason is that when a traffic accident occurs in a tunnel, the tunnel operation and management department has traditionally failed to effectively release safety warning information to the vehicles behind the accident, causing the rear vehicles to drive to the accident site in the tunnel without knowing it, thereby causing secondary accidents and expanding property and personnel losses. In some embodiments of the present invention, the guidance system also includes a broadcast module and a tunnel laser projection module; The broadcast module is used to broadcast reminders based on the vehicle information and location information of the abnormal vehicle when receiving an abnormal temperature warning signal or an initial fire alarm signal; when receiving a target fire alarm signal, it broadcasts reminders in the super-long tunnel and at the entrance and exit of the super-long tunnel according to the location of the automatic fire extinguishing area; The tunnel laser projection module is used to determine the driving position of the abnormal vehicle according to the positioning system when receiving the abnormal temperature warning signal, and project a reminder in front or on both sides of the abnormal vehicle according to the driving position.

[0033] In a specific embodiment of the present invention, the guidance system may also include a broadcast module and a tunnel laser projection module, and a high-gain directional broadcast may be set and synchronized. Specifically, when the broadcast module receives a temperature abnormality warning signal or an initial fire alarm signal, a broadcast reminder may be made according to the vehicle information of the abnormal vehicle and the location information of the tracking location, and a real-time broadcast may be made according to the real-time updated location; when a target fire alarm signal is received, a broadcast reminder may be made according to the location of the automatic fire extinguishing zone in the super-long tunnel and at the entrance and exit of the super-long tunnel; on the basis of traditional broadcasting, a sound synchronization algorithm is added to control the sound timing of each strong sound speaker, so as to achieve the effect that there is only one source of sound heard in the closed car, wherein the broadcasts in the tunnel are all human voices. The speakers currently used in the electromechanical industry take into account the consideration of playing music, and their frequency response range is very large, and the special use scenarios of the tunnel are not considered. However, some frequencies of human voices dissipate very slowly when propagating in the tunnel, making the entire sound field turbid and unclear. To this end, by using intelligent filtering technology for the sound source, the human voice is narrow-band processed, so that the sound emitted by the speaker is crisper and clearer.

[0034] The sound of each speaker in the tunnel is delayed accordingly according to its position (the sound timing of each speaker is different) so that the linear transmission sound is basically synchronized, that is, the sound heard from each speaker at any point on the tunnel line is basically synchronized, thereby greatly reducing reverberation and improving the listening experience.

[0035] (1) High-gain directional broadcasting: Strong sound: Improve the sound pressure output, the maximum sound pressure level reaches more than 130dB, realizing the strong sound pressure output of the sound reinforcement equipment.

[0036] Directionality: Through the unique acoustic sound-guiding structure design, the sound beam angle of the loudspeaker is ≤15°. Compared with traditional sound reinforcement equipment, it has better directivity, reduces the generalization and weakening of sound, enhances the penetration of sound, and realizes directional output of sound, focusing on sound reinforcement in a specific range.

[0037] HD: All kinds of warning and rescue audio such as sirens, fire alarms, disaster warnings and SOS have high sound frequencies, and the sound is harsh to the ear, but in fact such high-frequency sounds have good penetration and are less affected by environmental noise, which is suitable for early warning and alerting in emergency situations. The frequency of human speech is relatively low, belonging to medium-frequency sound, which is significantly different from high-frequency sound. Medium frequency is more conducive to maintaining voice clarity. High-gain penetrating broadcasting uses a combination of high frequency and medium frequency to achieve good penetration and high-frequency stimulation when playing warning audio, and at the same time maintains excellent human voice restoration when playing voice content, which is clear, smooth and accurate. It ensures that the strong sound equipment can have a good sound effect whether it is warning or commanding.

[0038] Long distance: In the acoustic calculation formula of "power for distance", the greater the sound pressure level, the longer the transmission distance can be achieved. A sound pressure level 3dB higher than other sound reinforcement equipment can double the transmission distance. High-gain penetrating broadcasting has a stronger sound pressure level and can achieve a farther transmission effect than traditional equipment.

[0039] Furthermore, the broadcast processed according to the above process can broadcast the vehicle information of the vehicle with abnormal temperature to remind the vehicles in the super-long tunnel and the vehicles entering and exiting the super-long tunnel to prevent the occurrence of secondary accidents.

[0040] Tunnels are limited by their own spatial structure. Once an accident occurs, it is easy to cause traffic jams, and secondary accidents may occur, making rescue work more difficult. As an important part of tunnel electromechanical engineering, tunnel emergency telephones and wired broadcasting modules are one of the most direct and effective means of control in tunnel emergencies. They play an important role in ensuring tunnel driving safety and tunnel accident rescue. When traffic abnormalities or driving accidents occur in tunnels, drivers and passengers can quickly notify tunnel managers through emergency telephone facilities. Tunnel managers can use wired broadcasting facilities to release information to people in the tunnel, guide vehicles or guide people to escape, so as to achieve the effect of rapid rescue and rapid troubleshooting.

[0041] While making a broadcast reminder, a reminder can also be made through a projection device. The current driving position of the vehicle with abnormal temperature can be determined based on the navigation and positioning system of the vehicle with abnormal temperature, and then the position that needs to be projected can be determined. The position can be located on both sides of the vehicle where the abnormal temperature is about to travel or on the ground in front (i.e., the position to be driven). Then, a projection reminder can be made based on the projection device. Similarly, reminders can also be made in other ways, for example, facial recognition of the driver is performed to obtain the mobile phone number, and reminders are made through text messages or telephone calls. The specific embodiments of the present invention are not limited here.

[0042] In some embodiments of the present invention, the sprinkler system 103 is further used to determine the water curtain sprinkler valve group according to the automatic fire extinguishing zone, and extinguish the fire of the burning vehicle according to the water curtain sprinkler valve group.

[0043] In a specific embodiment of the present invention, the shielding water curtain is mainly achieved by arranging a water curtain nozzle group at a certain interval in the tunnel. When a target fire alarm signal is received, it indicates that an abnormal vehicle has caught fire in the automatic fire extinguishing area. The water curtain control valve group arranged on both sides of the abnormal vehicle (i.e., the fire source) receives the target fire alarm signal, and opens the water curtain spray valve group on both sides of the automatic fire extinguishing area to form a strict fireproof water curtain with a certain thickness. The two water curtains form a fireproof section to surround the fire source. When the smoke from the tunnel fire spreads to the fireproof water curtain, the water curtain blocks the smoke and controls it within the fireproof separation section, while the outside of the water curtain is basically not affected by the smoke, providing a better environment for the evacuation of personnel. The shielding water curtain controls the spread of smoke on the one hand, and on the other hand, it can prevent air from entering the fireproof separation section, preventing the air on both sides of the fireproof separation water curtain from supplying oxygen to the fire area, so that the fire source lacks oxygen during its own combustion process and extinguishes itself, thereby achieving the purpose of extinguishing the fire. Under normal operation, the water curtain valve group is in a closed state. The shielding water curtain mainly plays the role of controlling the spread of smoke, isolating air from entering the fire scene, and preventing the spread of fire. Thereby reducing the danger of fire and smoke and creating good conditions for the evacuation of personnel.

[0044] Furthermore, highway tunnels are semi-enclosed space environments. Vehicles traveling in the tunnels will bring particulate pollutants such as automobile exhaust and dust, which will not only affect the driving vision in the tunnel, but also pollute the wall surface, causing maintenance difficulties. In order to better improve the air environment in highway tunnels and reduce secondary pollution to the surrounding environment of the tunnel, ventilation dilution is a means to reduce the concentration of tunnel pollutants. It is effective for all kinds of pollutants in the tunnel and is also the most commonly used highway tunnel pollution control measure at home and abroad. However, with the continuous increase in the length of highway tunnels, the required ventilation volume is also increasing, and there are corresponding restrictions on the longitudinal wind speed of the tunnel. This requires the use of segmented ventilation in the vertical shaft. However, it is still difficult to control the increase in ventilation volume, resulting in huge ventilation energy consumption. In addition, when a fire occurs, high-temperature, high-concentration toxic smoke will quickly be generated and accumulated in the tunnel, and traditional ventilation methods are prone to secondary disasters.

[0045] In a specific embodiment of the present invention, a tunnel-specific smoke and haze suppression air purifier can be installed inside the super-long tunnel. When there is no fire, the air can be purified by the tunnel-specific smoke and haze suppression air purifier. When a fire occurs, the smoke can be suppressed from sinking for a certain period of time to ensure the escape of personnel. The certain period of time is generally 15 minutes.

[0046] Further, such as Figure 3 As shown, the guidance system also includes a tunnel environment light module 105; the tunnel environment light module 105 is used to process the interior of the super-long tunnel through paint, lights and tunnel energy storage self-luminous traffic safety facilities, and adjust the light environment of the super-long tunnel.

[0047] In a specific embodiment of the present invention, the guidance system may also include a tunnel environment light module. The coating, lighting and traffic safety solutions are coupled in the super-long tunnel, which can solve the tunnel light environment problem. Its purpose is to reduce the lighting energy consumption and enhance the tunnel operation safety. It can be tested many times to make the tunnel light environment meet the requirements of safe parking sight distance, reduce the oppression of the tunnel space environment, and improve driving comfort. It can alleviate or eliminate the "black hole" and "white hole" phenomena in the tunnel, and can also achieve a multi-dimensional tunnel light environment that integrates low carbon and safety.

[0048] Furthermore, the inside of the super-long tunnel can be painted on both sides of the interior with paint. The paint can be nano-silicon anion paint. The specific setting can be based on the actual situation. For the arch range of the tunnel side wall above 3m high: spray blue nano-silicon anion paint (blue color number: 1201) + white nano-silicon anion paint to form a "blue sky and white clouds" landscape. For the tunnel side wall within the range of 0-2.7m high: spray white nano-silicon anion paint. For the tunnel side wall within the range of 2.7-3m high: spray dark green nano-silicon anion paint (dark green color number: 1163). Strengthen the painting of the emergency parking strip: along the driving direction of the tunnel, on the side wall 12m in front of the emergency parking strip, within 3m above the maintenance road, apply light green nano-silicon anion paint + 20m induction arrow (white multifunctional energy storage luminous paint) to improve the recognizability of the emergency parking strip area in front. Strengthen the painting at the pedestrian crossing: On both sides of the pedestrian crossing, within the height range of 0-2.7m above the inspection road, 10m on each side is painted with light green nano-silicon anion paint, and the escape direction is indicated by a striking white multifunctional energy storage luminous paint arrow sign, which is conspicuously distinguished from the white painting on the wall itself, and improves the induction of safe evacuation direction in emergency situations. The door frame is highlighted with an orange arc structure to increase the recognizable distance. This can improve the overall beauty of the tunnel painting, enhance driving comfort, and improve the tunnel coating material's resistance to oil stains and cleaning ability, and can also provide emergency escape indication performance in the event of fire or unexpected power outages.

[0049] Furthermore, lights, such as DFLED lights, can be installed in extra-long tunnels to illuminate the tunnel. This can reduce or alleviate the visual impact of lamp glare on drivers, lower the PN junction temperature of the lamp, ensure that the lamp service life is greater than 50,000 hours, and save more than 20% of lighting design energy consumption, verifying that the afterglow of the DFLED lamp has guiding and indicating performance in the event of a power outage.

[0050] Furthermore, tunnel energy storage self-luminous traffic safety facilities can be installed in super-long tunnels. Such facilities can reconstruct the visual guidance system, improve the guidance efficiency, reduce visual errors, and relieve visual fatigue. They can also improve the anti-fouling performance of traffic safety facilities and reduce the frequency of later maintenance and cleaning. In dark conditions, they can provide delayed self-luminescence to serve as an indicator lighting.

[0051] The tunnel environment is relatively dim and has low visibility. The driver's field of vision is controlled within a narrow and long range, and the continuity of the field of vision is blocked. In addition, there is a lack of an effective reference system in the tunnel, and the driver's sense of speed, distance and time is relatively significantly reduced. It is easy to produce passive driving fatigue due to the lack of effective stimulation. In some embodiments of the present invention, the tunnel laser projection module is also used to process the interior of the super-long tunnel through multiple visual fatigue relief lighting strips, and to adjust the projection of multiple visual fatigue relief lighting strips.

[0052] In a specific embodiment of the present invention, a tunnel laser projection module (i.e., a landscape belt laser projection device) can be set in an ultra-long tunnel, and multiple visual fatigue relief lighting belts can be set. Each fatigue relief belt system consists of 10 sets of tunnel light machines. The tunnel light machine adopts an advanced integrated design. Each set of equipment is a node, which communicates through a network system. The control system is installed in the equipment room, and the entire system can be managed uniformly. Each set of "tunnel light machine" only needs to be connected to the machine room through a single-mode optical fiber and connected to the control system to achieve unified playback, information release, and system settings of all nodes. Therefore, the system has high system integration, simple architecture, and convenient installation. It is a new generation of products specially developed for relieving drivers' visual fatigue in long and large tunnels. The tunnel light machine display system integrates the functions of many devices such as signal transmission, signal conversion, graphic workstation, central control, and protective box. It adopts a new design. One device is a node, and the system nodes can be expanded arbitrarily. Each node only needs to reserve power and optical fiber. The system is simple to install and has low requirements for the installation environment. The system has built-in centralized management and control functions. It supports real-time monitoring of equipment operation, remote control of equipment, and provides interfaces to connect third-party control systems; it supports multi-machine joint control and real-time backup. The built-in visual fatigue relief content software, safe evacuation plan content software, and traffic warning content software all support sensor-triggered playback, remote publishing playback, local automatic playback, and other modes. At the same time, the content can be edited and replaced according to the increase or decrease of device nodes. The equipment adopts a highly integrated product with an integrated body. During the installation and use, the special environment of the tunnel is fully considered, and the installation point has been verified multiple times. At the same time, each system has automatic dust removal and self-cleaning functions, the light source has an IP6x dustproof level, and has windproof, rainproof, dustproof, anti-collision, and air cooling functions. Therefore, when the vehicle is driving in an ultra-long tunnel, the driver's emotions and vision can be adjusted, reducing the driver's monotony, tension, irritability, fear and other negative emotions, so that the driver's vision and emotions can be adjusted temporarily, and the driving safety and comfort can be increased.

[0053] Furthermore, with the increasing awareness of environmental protection, the conventional waterproofing measure for groundwater treatment during tunnel construction is to install drainage boards after grouting the surrounding rock to form a waterproof layer. This is not only difficult to construct and expensive, but also the hollows and holes formed by the casting of the primary and secondary linings during the convergence and deformation process are easy to puncture the waterproof board and cause tunnel leakage. It is difficult to find and deal with the leakage points during operation. In recent years, there have also been engineering cases of spraying organic waterproof membranes on the initial lining for waterproofing. The waterproof coating can better overlap the primary lining and the secondary lining to reduce puncture and leakage. However, due to the airtightness and humidity of the tunnel environment, if it is a water-based environmentally friendly material, it is not suitable to dry and form a film. If an organic volatile solvent material is used, it is toxic to the operators and will cause combustion and explosion accidents when encountering open flames. Therefore, anti-humidity waterproof coatings can be used inside super-long tunnels to solve the problem that coating-type waterproof coatings are difficult to solidify in a humid environment.

[0054] Furthermore, with the construction of more and more tunnels in cold regions, the problem of freezing damage during tunnel construction is becoming more and more frequent. The tunnel entrance, as the initial and throat part of the tunnel, is affected by rain, snow or temperature changes all year round, and often suffers from freezing damage. The freezing damage of the tunnel mainly includes ice hanging in the lining hole, water seepage, lining cracking, etc. In a specific embodiment of the present invention, an anti-moisture insulation coating can be used inside the super-long tunnel to protect the super-long tunnel and solve the problem of poor water resistance of coating-type insulation materials.

[0055] In order to better implement the ultra-long tunnel intelligent linkage system in the embodiment of the present invention, based on the ultra-long tunnel intelligent linkage system, the embodiment of the present invention also provides an ultra-long tunnel intelligent linkage method, such as Figure 4 As shown, the fire detection and processing method for super-long tunnels includes: S401, monitoring vehicles in the super-long tunnel, when an abnormal vehicle exceeding the temperature threshold is detected, sending a temperature abnormality warning signal and tracking and locating the abnormal vehicle, when the abnormal vehicle catches fire, determining the automatic fire extinguishing zone according to the location information of the abnormal vehicle, and guiding the abnormal vehicle to the automatic fire extinguishing zone through the guidance system, and sending an initial fire alarm signal, when the abnormal vehicle stops driving in the automatic fire extinguishing zone, updating the initial fire alarm signal, and sending the updated target fire alarm signal; S402: When an initial fire alarm signal is received, abnormal vehicles are guided to the automatic fire extinguishing area, and vehicles in the extra-long tunnel are reminded; S403, when an initial fire alarm signal is received, the automatic fire extinguishing area is controlled to perform preparation work, and when a target fire alarm signal is received, the abnormal vehicle in the automatic fire extinguishing area is extinguished; S404. When an initial fire alarm signal is received, the smoke suppression device within the preset range of the automatic fire extinguishing area is controlled to perform preparation work. When a target fire alarm signal is received, the smoke suppression device is started, and the degree of smoke generated during the abnormal vehicle fire is suppressed according to the smoke suppression device.
