[0001] The present invention relates to the field of new energy application technology, and in particular to an energy-saving lighting system and method utilizing tunnel piston wind power generation. Background Art

[0002] In recent years, with the rapid increase in the number of vehicles in my country, the construction of highways in the western region has been intensified. The western region is mostly mountainous and hilly. Therefore, with the increase in the number of tunnel construction, the energy consumption problem inside the tunnel has become increasingly prominent. The lighting equipment in the tunnel needs to be continuously powered, but the cost of long-distance power supply is high and the utilization rate of solar energy is limited.

[0003] The tunnel piston effect refers to the fact that when a vehicle is driving in a tunnel, due to the narrow space between the car and the tunnel wall, the car acts like a huge piston, compressing the air in front of it as it moves forward and forming a low-pressure area behind it.

[0004] When a vehicle passes through the tunnel, piston wind can be formed in the tunnel. Using tunnel piston wind to generate electricity and provide lighting in the tunnel is an effective new energy-saving solution, which can achieve self-sufficiency of energy inside the tunnel. However, the existing technical solution of using tunnel piston wind to generate electricity still has some shortcomings in terms of energy utilization efficiency, structural simplicity and practicality.

[0045] Wherein: x and y represent the position of the helix on a plane perpendicular to the central axis of the turbofan 303, and are used to locate the distance of each point forming the blade profile from the central axis.

[0053] An energy-saving lighting method using tunnel piston wind power generation, using the above energy-saving lighting system using tunnel piston wind power generation, includes the following steps: S1. Power generation: When the vehicle passes through the entrance of the tunnel 9, the piston wind around the vehicle is guided to the vortex generator 3 through the guide plate group 1 and the guide wing group 2, and finally enters the turbofan 303. The turbofan 303 generates a vortex effect under the action of the piston wind airflow, driving the motor shaft of the permanent magnet synchronous motor 302 to rotate, converting mechanical energy into electrical energy, which is transmitted to the energy storage battery 4 through the wire.

[0054] S2. Lighting: When the laser radar sensor 602 integrated in the induction lighting 6 detects a vehicle passing by 100-150m in advance, the induction lighting 6 lights up, and the light intensity sensor 603 dynamically adjusts the brightness according to the environment of the tunnel 9 to provide basic lighting in the tunnel 9; after the vehicle leaves, the induction lighting 6 automatically turns off, thereby achieving precise management of the lighting in the tunnel 9 and optimizing energy efficiency.

When the car approaches the entrance of tunnel 9 by 100 meters, the laser radar sensor 602 detects that the vehicle has passed, the induction lamp 6 is turned on, and the light intensity sensor 603 dynamically adjusts the brightness according to the environment of tunnel 9. If the light intensity sensor 603 detects that the light intensity in tunnel 9 is low, the brightness of the induction lamp 6 will be increased; if the light intensity sensor 603 detects that the light intensity in tunnel 9 is high, the brightness of the induction lamp 6 will be reduced to provide basic lighting for tunnel 9. During this period of time, the car successfully passes through the entrance of tunnel 9 and enters the interior of tunnel 9. When the car leaves the detection range of the laser radar sensor 602, the induction lamp 6 automatically turns off. In this way, the system can dynamically adjust the lighting brightness according to actual needs, improve the energy efficiency of tunnel 9 and optimize the driver experience.

[0056] S3. Ventilation: When the air quality sensor 7 detects that the carbon monoxide and other pollutant gases in the tunnel 9 exceed the standard, or a fire occurs in the tunnel 9 and releases a large amount of smoke which is detected by the smoke sensor 8, the electric push rod 103 retracts and drives the movable guide plate 102 to unfold flatly, and the central control unit 5 controls the permanent magnet synchronous motor 302 to switch to electric mode operation, so that the tunnel 9 is quickly ventilated to ensure the safety of the passengers in the tunnel 9.
