Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation lighting, and more specifically to a new type of tunnel lighting device based on wind energy generation caused by vehicle passing. Background Art

[0002] With the acceleration of the urbanization process and the continuous growth of transportation demand, tunnels, as important traffic infrastructure, their safety and comfort have attracted more and more attention. Tunnel lighting, as one of the key factors to ensure driving safety, its energy consumption and lighting effect have become the focus of research. Traditional tunnel lighting systems usually adopt fixed lighting equipment, with 24-hour uninterrupted lighting, lacking effective dimming control means, resulting in serious waste of electric energy; at the same time, due to the large difference in illuminance inside and outside the tunnel, it is bright outside and dark inside during the day, and dark outside and bright inside at night, which makes drivers feel uncomfortable visually, slow down for safe driving, and easily form traffic jams. There are the following two power supply methods for existing tunnel lighting. One is to use traditional grid power distribution for lighting, which is achieved by laying grids, but it requires a large amount of manpower and material resources and cannot achieve effective energy conservation and emission reduction; the other is to use new tunnel lighting technologies that have emerged in recent years, including new energy power supply methods such as wind energy generation and solar energy. Although these new energy power supply methods have achieved energy conservation and emission reduction to a certain extent, single new energy power supply often has problems such as low power generation efficiency, unstable power supply, and easy occurrence of faults, making it difficult to fully meet the needs of tunnel lighting.

[0003] In view of the above problems, the utility model proposes a new type of tunnel lighting device based on wind energy generation caused by vehicle passing. This device adopts a power supply method that combines wind energy generation and grid power distribution. It utilizes the wind energy generated by vehicles driving at high speed, converts the wind energy into electric energy through wind energy generation equipment, and preferentially uses the wind energy generation to directly supply power to the tunnel lighting system. When there is a surplus in the wind energy generation power supply, the generated electric energy is stored. The tunnel lighting system can mainly rely on wind energy for power supply to achieve self-sufficiency in lighting power supply; and when the reserve of wind energy generation is insufficient, it can automatically switch to supplementary power supply through grid power distribution to ensure the stability and reliability of tunnel lighting. This device can not only make full use of the wind energy resources in the tunnel, reduce energy consumption, but also has the advantages of energy conservation, environmental protection, and intelligence; at the same time, through intelligent dimming design, it can automatically adjust the lighting brightness according to the light difference inside and outside the tunnel and the change of traffic flow, providing a more comfortable driving environment for drivers. Summary of the Invention

[0004] In view of the above problems, the present utility model proposes a new type of tunnel lighting device based on wind energy generation generated by vehicle passage. This device adopts a power supply method that combines wind energy generation and grid power distribution. It utilizes the wind energy generated by vehicles traveling at high speed, and through a wind energy generation device, it converts the wind energy into electrical energy. It preferentially uses the wind energy generated to directly supply power to the tunnel lighting system. When there is a surplus in the power supply from wind energy generation, the generated electrical energy is stored. The tunnel lighting system can mainly rely on wind energy for power supply to achieve self-sufficiency in lighting power supply. When the stored wind energy generation is insufficient, it can automatically switch to supplementary power supply through grid power distribution to ensure the stability and reliability of tunnel lighting. This device can not only make full use of the wind energy resources in the tunnel, reduce energy consumption, but also has the advantages of energy conservation, environmental protection, and intelligence. At the same time, through intelligent dimming design, it can automatically adjust the lighting brightness according to the light difference inside and outside the tunnel and the change in traffic flow, providing a more comfortable driving environment for drivers.

[0005] In order to achieve the above objectives, the technical solution adopted by the present utility model is as follows:

[0006] The present utility model provides a new type of tunnel lighting device based on wind energy generation generated by vehicle passage, including a wind energy power supply component, a commercial power supply component, and a power supply control component;

The windmill is connected to the generator through the speed increaser. The alternating current generated by the generator sequentially passes through the first rectifier and the first voltage stabilizer. The first rectifier is used to perform full-wave rectification on the alternating current generated by the generator, and the first voltage stabilizer is used to stabilize the voltage after full-wave rectification by the first rectifier and output 12V - 14V direct current to supply power to the new type of tunnel lighting device. Specifically, the windmill is connected to the generator through the speed increaser, and the wind energy generated when a vehicle passes by is used to drive the generator to operate, so as to convert the wind energy into electrical energy and realize power generation, that is, convert the wind energy into alternating current; the alternating current generated by the generator is subjected to full-wave rectification by the first rectifier; then the voltage after full-wave rectification by the first rectifier is transmitted to the first voltage stabilizer for voltage stabilization and output 12V - 14V direct current to directly supply power to the lighting device;

[0008] The commercial power supply component includes a transformer, a second rectifier, and a second voltage stabilizer. The transformer is used to receive commercial power (220V alternating current) and convert it into 24V alternating current, then the 24V alternating current is subjected to full-wave rectification by the second rectifier, and finally the second voltage stabilizer is used to output a constant 12V direct current;

[0013] The ambient light judgment module is driven by an STM32 processor. The light collecting surface of the ambient light judgment module faces the tunnel center. According to the different resistance values presented by the ambient light change, the STM32 processor collects the group values of the ambient light module to obtain the light intensity condition corresponding to the tunnel environment;

[0014] The pulse modulation module is driven by an STM32 processor. Specifically, the STM32 processor is used to generate PWM to drive the MOS tube.

Combined with the ambient light judgment module, accurate control of the lighting brightness can be effectively achieved.

[0015] Further, the oncoming vehicle judgment module includes a laser ranging sensor and a power supply switch. The laser ranging sensor is used to detect whether a vehicle is about to pass through the installation area of the new tunnel lighting device, and send the detection signal to the STM32 processor for analysis and judgment, and control the on / off of the power supply switch according to the judgment result. Specifically, when a vehicle is detected to enter the installation area of the device, the power supply switch of the lighting device at a preset distance in the direction of the vehicle entry is controlled to turn on. When no vehicle is detected to enter the installation area of the device for a period of time, the power supply switch of the lighting device in this area is controlled to turn off.

[0016] The intelligent control principle of the lighting of the above device is that the MOS tubes of the pulse modulation module and the MOS tube of the power supply switch are both connected in series to the main power supply circuit of the light source and are respectively electrically connected to the STM32 processor; the oncoming vehicle judgment module is connected to the STM32 processor through a serial port, sends the oncoming vehicle judgment module signal to the STM32 processor for analysis and judgment, and controls the MOS tube of the power supply switch to turn on or off according to the judgment result to realize the on / off of the lighting source; the STM32 processor is connected to the ambient light judgment module, is used to collect the ambient light intensity information sent back by the ambient light judgment module for comprehensive judgment, and generates a PWM to adjust the duty cycle of the switch of the MOS tube of the pulse modulation module to adjust the brightness of the light source.

[0017] The windmill includes fan blades and a ring-shaped wire mesh. The length of the fan blades is not less than 150 mm, and the diameter of the whole windmill is not less than 350 mm. However, considering operational safety, the size of the windmill is not greater than the 750 mm width of the inspection road. The ring-shaped wire mesh is used to protect the fan blades to ensure the normal operation of the windmill.

[0018] The speed increaser adopts a gear transmission ratio of 5:1 to improve the efficiency of wind energy power generation, and at the same time can effectively avoid the influence of excessive wind speed on the generator, playing a role in protecting the generator.

[0019] Both the first rectifier and the second rectifier include a full-wave rectifier circuit, and the full-wave rectifier circuit is mainly constructed by 1N4007 diodes.

[0020] Both the first voltage regulator and the second voltage regulator include a zener diode, an electrolytic capacitor and a ceramic capacitor, and are used to realize the voltage regulation process of the full-wave rectifier circuit.

[0021] The charge and discharge module adopts the CN3767 chip, which is used to realize the charge and discharge management of the energy storage battery. When the voltage of wind power generation is greater than the preset threshold, the wind power generation directly supplies power to the lighting equipment; and the surplus electric energy after the wind power generation supplies power is transmitted to the energy storage battery through the charge and discharge module for energy storage; when the voltage of wind power generation is lower than the preset threshold, the electric energy stored in the energy storage battery is released through the charge and discharge module to supplement the power supply for the lighting equipment; when the voltage of wind power generation is lower than the preset threshold and the electric energy stored in the energy storage battery is insufficient, the municipal power supplies power to the lighting equipment.

[0022] The beneficial effects of the present utility model:

When the wind power generation power is sufficient, the tunnel lighting system can completely rely on wind power supply to achieve self-sufficiency; when the wind power generation power is insufficient, it can automatically switch to grid power distribution for supplementary power supply, effectively realizing energy conservation and emission reduction, and at the same time, ensuring the stability and reliability of tunnel lighting.

The installation of this device is as Figure 2 shown.

[0041] As an implementation manner of this embodiment, the windmill includes fan blades and a ring-shaped wire mesh.

To improve the efficiency of wind power generation, a speed increaser is designed between the windmill and the generator in this application, which can not only improve the power generation efficiency of the generator but also avoid the impact on the generator when the wind speed is too high, playing a role in protecting the generator.
