Description

Technical Field

[0001] The present invention relates to the technical field of highway traffic safety equipment, and in particular to a guidance device used in highways. Background Art

[0002] Highway guidance equipment is a kind of safety warning light, also known as guidance fog light. It is mainly installed on rainy and foggy highways, national highways, mountain roads, sections with many bends and large amplitudes, as well as interchanges and service area diversion areas. At the same time, it can be deployed at the entrance of the ramp in conjunction with the oncoming vehicle warning device to ensure driving safety. It has functions such as synchronous flashing, anti-rear-end collision warning, and display reminders.

[0003] Existing highway guidance equipment has the following defects: 1. Insufficient optical performance: The direct-plug LED light source is uneven in light emission, the visible distance is short (usually <300 meters), and it is easy to produce glare. In addition, the existing dot matrix display module has poor display effect, and some strokes of characters are not clear; secondly, the luminous display area of ​​conventional products on the market accounts for less than 50%, which is a low proportion; 2. Poor structural reliability: The solar panel and the main body are installed separately, which is easily damaged by wind vibration, and the product waterproof level is lower than IP65; 3. Difficult maintenance: Program upgrades require the disassembly of the equipment, resulting in increased operation and maintenance costs; 4. Weak environmental adaptability: The traditional ABS material shell is prone to aging under ultraviolet radiation, and the metal parts have insufficient salt spray resistance; when powered by solar energy, it is difficult to achieve longer battery life with a small solar panel and lithium battery capacity.

[0004] Therefore, how to design an induction device for use on highways with a simpler and more reasonable structure, better display effect, easier recognition by drivers and passengers, and better adaptability to different installation scenarios has become a technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is how to design an induction device for use on highways with a simpler and more reasonable structural design, better display effect, easier to be recognized by drivers and passengers, and better adaptable to different installation scenarios.

[0006] To achieve the above-mentioned purpose, the present invention provides an induction device for use on highways, comprising a device body, the device body including an external shell; a light board is mounted on the surface of one side of the shell, and lamp beads are arranged on the outer surface of the light board; a mask is mounted on the outer side of the light board on the shell; the feature is that the lamp beads are surface-mount LED lamp beads; and aspheric lenses protruding inward are arranged on the inner surface of the mask and at positions corresponding to the positions directly opposite the surface-mount LED lamp beads.

[0007] In this way, the above technical solution improves the shortcomings of existing conventional products. Conventional products use direct-plug LED light sources, which are protected by a transparent mask in front. Among the luminous angles of the direct-plug light source, only a small amount of light is emitted vertically within 30 degrees and is received by the human eye.

[0008] In this device solution, the lamp beads use SMD LED lamp beads. Inwardly protruding aspheric lenses are installed on the inner surface of the mask, corresponding to the positions directly opposite the SMD LED lamp beads. This allows the SMD LED lamp beads to emit light through the aspheric lens. A large amount of light within the aspheric collimated luminous angle is within a 30-degree range, and the vast majority of the light is directed vertically toward the observer. Furthermore, the diameter of the luminous surface of a single light source after being collimated and guided by the lens is larger, and its fog penetration can reach over 500 meters, which is 100% longer than the fog penetration distance of conventional products. This allows the vast majority of light to be emitted vertically and better received by the human eye, and the light is more uniform, visible from a greater distance, better avoiding glare and improving the device's display effect.

[0009] As an optimization, the aspheric lens and the mask are integrally formed.

[0010] In this way, the aspheric lens and the mask are obtained by integrally molding, which makes the structural design simpler and more convenient to manufacture.

[0011] As an optimization, the diameter of the aspheric lens is 6-7mm; the wavelength range of the SMD LED lamp beads is 590-592nm.

[0012] In this way, the diameter range of the aspheric lens is more reasonable, the wavelength range design of the SMD LED lamp beads is more reasonable, and the data matching between the two is better.

[0013] As an optimization, the diameter of the aspheric lens is 6.2mm; the wavelength of the SMD LED lamp bead is 591nm; the mask is made of optical-grade PC material, and its refractive index is 1.585.

[0014] In this way, the parameter design is more reasonable, which can make the light emission more uniform and improve the display effect.

[0015] As an optimization, the distance between the surface of the SMD LED lamp bead and the inner side of the mask is 3 mm, and the distance between the aspheric lens and the surface of the SMD LED lamp bead is 1.5 mm.

[0016] In this way, the distance between the surface of the SMD LED lamp bead and the inner side of the mask, as well as the distance between the aspheric lens and the surface of the SMD LED lamp bead are designed more reasonably, and the data matching is better.

[0017] As an optimization, one or more display areas are provided on the light board, and the display area is designed to have a rectangular structure. In the display area, 16 rows and 16 columns of SMD LED lamp beads are arranged in rows horizontally and columns vertically.

[0018] In this way, the arrangement of the SMD LED lamp beads in the display area is more reasonable, and the words can be displayed better.

[0019] As an optimization, the center distance between any two adjacent SMD LED beads in the display area is 9mm.

[0020] In this way, the SMD LED lamp beads are matched with the aspheric lens, so that the display area is increased compared with the conventional structure, thereby improving the display effect.

[0021] As an optimization, two display areas are arranged vertically side by side on the light panel; a concave portion with a flat rectangular structure design is formed on the outer surface of the mask at positions corresponding to the two display areas.

[0022] In this way, two display areas are set up to display two words, which can better provide warnings and reminders; and the structural design of the mask is simpler and more reasonable.

[0023] As an optimization, the inner edge of the mask protrudes inward to form a rectangular mounting ridge, and the inner edge of the mounting ridge is provided with a mounting groove with a rectangular structure design. A sealing ring is arranged in the mounting groove, and the inner side of the sealing ring is supported on the edge of the mounting opening on the shell to form a seal.

[0024] In this way, by providing a mounting flange, providing a mounting groove on the mounting flange and arranging a sealing ring, the sealing effect can be improved and water vapor can be better prevented from entering the interior.

[0025] Furthermore, the sealing ring adopts a Y-shaped sealing ring. In this way, the size of the installation groove can be compensated, making the seal more reliable and better preventing water vapor from entering the interior.

[0026] As an optimization, a plurality of screw holes are arranged at intervals along the mask contour direction and corresponding to the mounting protrusion on the mask, and each is provided with a screw, and the screw holes are located outside the mounting groove; and the screws are threadedly connected to the shell.

[0027] In this way, the positions of the screws are arranged more reasonably, and the mask is more convenient to disassemble and assemble.

[0028] Furthermore, a weight-reducing groove arranged along the direction of the mask screw hole is provided on the inner surface of the mounting protrusion and between any two screw holes.

[0029] In summary, the above-mentioned induction device has the characteristics of simpler and more reasonable structural design, better display effect and is easier to be identified by drivers and passengers. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] like Figures 1 to 10 As shown, a guidance device for use on highways includes a device body, which includes an external shell 1; a light board 2 is mounted on the surface of one side of the shell, and lamp beads 3 are arranged on the outer surface of the light board; a mask 4 is mounted on the outer side of the light board on the shell; the lamp beads are surface-mount LED lamp beads; and aspheric lenses 5 are provided on the inner surface of the mask and at positions corresponding to the surface-mount LED lamp beads, which are protruding inward.

[0056] In this way, the above technical solution improves the shortcomings of existing conventional products. Conventional products use direct-plug LED light sources, which are protected by a transparent mask in front. Among the luminous angles of the direct-plug light source, only a small amount of light is emitted vertically within 30 degrees and is received by the human eye.

[0057] In this device solution, the lamp beads use SMD LED lamp beads. Inwardly protruding aspheric lenses are installed on the inner surface of the mask, corresponding to the positions directly opposite the SMD LED lamp beads. This allows the SMD LED lamp beads to emit light through the aspheric lens. A large amount of light within the aspheric collimated luminous angle is within a 30-degree range, and the vast majority of the light is directed vertically toward the observer. Furthermore, the diameter of the luminous surface of a single light source after being collimated and guided by the lens is larger, and its fog penetration can reach over 500 meters, which is 100% longer than the fog penetration distance of conventional products. This allows the vast majority of light to be emitted vertically and better received by the human eye, and the light is more uniform, visible from a greater distance, better avoiding glare and improving the device's display effect.

[0058] In this specific embodiment, the aspheric lens and the mask are integrally formed.

[0059] In this way, the aspheric lens and the mask are obtained by integrally molding, which makes the structural design simpler and more convenient to manufacture.

[0060] In this specific embodiment, the diameter of the aspheric lens is 6-7 mm; the wavelength range of the SMD LED lamp bead is 590-592 nm.

[0061] In this way, the diameter range of the aspheric lens is more reasonable, the wavelength range design of the SMD LED lamp beads is more reasonable, and the data matching between the two is better.

[0062] In this specific embodiment, the diameter of the aspheric lens is 6.2 mm; the wavelength of the SMD LED lamp bead is 591 nm; the mask is made of optical-grade PC material, and its refractive index is 1.585.

[0063] In this way, the parameter design is more reasonable, which can make the light emission more uniform and improve the display effect.

[0064] In this specific embodiment, the distance between the surface of the SMD LED lamp bead and the inner side surface of the mask is 3 mm, and the distance between the aspheric lens and the surface of the SMD LED lamp bead is 1.5 mm.

[0065] In this way, the distance between the surface of the SMD LED lamp bead and the inner side of the mask, as well as the distance between the aspheric lens and the surface of the SMD LED lamp bead are designed more reasonably, and the data matching is better.

[0066] In this specific embodiment, one or more display areas 6 are provided on the light board, and the display area is designed to be a rectangular structure, and 16 rows and 16 columns of SMD LED lamp beads are arranged in rows horizontally and columns vertically in the display area.

[0067] In this way, the arrangement of the SMD LED lamp beads in the display area is more reasonable, and the words can be displayed better.

[0068] In this specific embodiment, the center distance between any two adjacent SMD LED lamp beads in the display area is 9 mm.

[0069] In this way, the SMD LED lamp beads are matched with the aspheric lens, so that the display area is increased compared with the conventional structure, thereby improving the display effect.

[0070] In this specific embodiment, two display areas are arranged vertically side by side on the light board; an inner concave portion 7 with a flat rectangular structure is formed on the outer surface of the mask and at positions corresponding to the two display areas.

[0071] In this way, two display areas are set to display two words, which can better provide warnings and reminders; and the structural design of the mask is simpler and more reasonable.

[0072] In this specific embodiment, the inner edge of the mask protrudes inward to form a rectangular mounting flange 8, and the inner edge of the mounting flange is provided with a mounting groove with a rectangular structure design. A sealing ring 9 is arranged in the mounting groove, and the inner side of the sealing ring is supported on the edge of the mounting opening on the shell to form a seal.

[0073] In this way, by providing a mounting flange, providing a mounting groove on the mounting flange and arranging a sealing ring, the sealing effect can be improved and water vapor can be better prevented from entering the interior.

[0074] Furthermore, the sealing ring adopts a Y-shaped sealing ring. In this way, the size of the installation groove can be compensated, making the seal more reliable and better preventing water vapor from entering the interior.

[0079] Thus, in the above-mentioned shell structure, compared with the original structure in which the solar panels are installed separately from the main body, this structure installs the solar panels on the three side surfaces and the upper end face of the shell, so that the four solar panels are better integrated with the shell, and the entire structural design is simpler and more compact, which can better resist wind vibration; and by attaching solar panels on all sides and the upper end, the product waterproof level can reach IP65. Secondly, the area of ​​the solar panel is larger, which can better charge and supply electricity. Finally, the layout of the light panel is more reasonable, so that it covers the front side of the upper shell and the lower shell, making the area of ​​the entire display area larger and able to better complete the display; the set clearance opening can better facilitate the heat dissipation of the light panel.

[0080] Furthermore, the upper and lower shells are made of materials with high insulation and voltage resistance ratings. Conventional products on the market have a high insulation and voltage resistance rating of 2000V and a protection level of IP54. This technical solution uses materials with high insulation and voltage resistance ratings, and the mounting structure is made of hard-anodized aluminum alloy. The mains power supply structure is separated from the solar power supply circuit structure, and the voltage resistance rating of all externally accessible parts can reach 4000V. The product structure design adopts a combined external mounting bracket, and the induction equipment protection level reaches IP66, which can adapt to even harsher operating environments.

[0091] In this technical solution, the lower shell also includes a support shell 23 that is integrally formed and arranged below the lower cover plate and has an overall rectangular cylindrical structure design. A cut-out opening 24 is provided at the rear side of the support shell and at a position corresponding to the external download interface.

[0092] In this way, the structural design of the lower shell is simpler. By providing the cut-out clearance opening, maintenance personnel can reach in through the cut-out clearance opening and operate the switch, external download interface and power supply line.

[0093] In this technical solution, both sides of the upper surface of the lower cover are drawn downward to form a first installation box 25 with an open upper end, and the first installation box is used to install and arrange a radar vehicle inspection module 26 or an infrared vehicle inspection module.

[0099] In this technical solution, an antenna 33 is installed at a corner position at the upper end of the upper shell.

[0100] In this way, arranging the antenna inside the upper shell can protect the antenna.

[0101] like Figures 15 to 23 As shown, the present technical solution also discloses an installation structure of an induction device, including a vertically arranged installation tube 34 with a rectangular cylindrical structure design at the lower end of the device shell; a fixed support plate 35 extending outward is respectively provided at the four corner positions on the outside of the installation tube at the lower end of the device shell, and a threaded connection hole 36 is respectively provided at the far end position of the lower end surface of the fixed support plate; the inner hole of the installation tube forms a plug-in hole and can be used to connect with the first installation fixing structure; the four threaded connection holes can each be used to connect with the second installation fixing structure, the third installation fixing structure and the fourth installation fixing structure.

[0108] In this way, the first mounting and fixing structure adopts a mounting support rod, the upper end of the mounting support rod is inserted into the socket hole, and the lower end of the mounting support rod is used to be installed and fixed on the guardrail post. The entire structural design is simpler, and it is more convenient to install and fix the equipment on the guardrail post.

[0109] In this technical solution, a vertical limiting structure is provided on the mounting tube to limit the mounting support rod inserted into the mounting tube from falling out from the lower end; the vertical limiting structure includes a threaded limiting hole 39 provided on one side surface of the mounting tube and is used in conjunction with a limiting screw, so that the inner end of the limiting screw can abut and support the mounting support rod in the mounting tube to limit the axial sliding of the mounting tube and the mounting support rod.

[0132] In this technical solution, two abutment ribs 51 are connected in pairs between the two side surfaces of the upper end of the interior of the installation tube, and the upper end of the installation support rod can be supported by abutting against the lower side of the abutment ribs.

[0133] In this way, by providing the abutment ribs, on the one hand, the structural strength of the installation tube can be improved, and on the other hand, the abutment and limiting of the installation support rod can be better performed.

[0134] In this technical solution, a connecting plate with an L-shaped structure is integrally formed on the outer side of each fixing column, and both ends of the connecting plate are connected to the inner circumference of the lower end of the equipment shell.

[0135] In this way, the structural strength of the lower shell of the device is improved.

[0136] like Figure 24 As shown, an induction device control system is also disclosed; it includes a main control module arranged in the device shell, and the main control module is integrated with an induction device MCU control circuit 52, a solar circuit 53 and an MPPT charging management circuit 54; the solar circuit is used to be electrically connected to the solar panel 14, and the induction device MCU control circuit is used to be electrically connected to the light board; and the solar circuit is also electrically connected to the induction device MCU control circuit and the MPPT charging management circuit respectively, and the MPPT charging management circuit is also electrically connected to the battery 55 in the device shell; the battery is used to be electrically connected to the induction device MCU control circuit for power supply; it also includes a coordinator 56, and a coordinator MCU control circuit 57 and a GPS module 58 are integrated on the electric control board in the coordinator, and the coordinator MCU control circuit and the GPS module are electrically connected; and the coordinator MCU control circuit is connected to the induction device MCU control circuit signal; the coordinator MCU control circuit is used to be connected to the weather station terminal 59 signal; and a power supply circuit 60 is also provided, and the power supply circuit is electrically connected to the coordinator MCU control circuit for power supply.

[0137] Specifically, the coordinator is further provided with a coordinator wireless communication module 61, and the induction device MCU control circuit is connected with an induction device wireless communication module 62, so that the coordinator wireless communication module and the induction device wireless communication module are signal-connected.

[0138] In this way, the system design is simpler and can better complete the transmission of information.

[0139] Specifically, the battery is a lithium battery module.

[0140] Specifically, it also includes a collision detection circuit 63 and a dynamic monitoring circuit 64, and both the collision detection circuit and the dynamic monitoring circuit are electrically connected to the MCU control circuit of the induction device.

[0141] When the above system is working, it obtains the latitude and longitude of the installation point of the guidance equipment (fog lamp) according to the GPS module, so as to know the lighting conditions of the four seasons on site. Then, it combines the meteorological data given by the weather station terminal and obtains weather data to control the energy consumption of the guidance equipment (fog lamp) and reduce the power consumption of the fog lamp. Specific strategies include: 1. Obtain the longitude and latitude from the coordinator and calculate the sunshine conditions in the area and the average daybreak and sunset times for each quarter: 2. Set the average daily dawn and dusk time based on the acquired time, and turn the fog lights on and off; 3. The coordinator obtains the regional meteorological data "ice, snow, rain and fog" to set the fog light guidance; 4. Energy consumption control can be achieved by monitoring the voltage, current and battery level of the fog lamp solar panel; Through the above data, when there is sufficient light in the area and the fog lamps have sufficient power, the fog lamps will be turned on and flash to induce induction in bad weather; when the light in the area is low and the fog lamps have low power, the fog lamps will enter low power consumption mode for charging, and the fog lamp status will be reported every hour. When the power reaches the threshold, the fog lamps will work normally.

[0142] Induced device battery charging control strategy: 1. When there is sufficient sunlight on site, charge the battery slowly at 0.2C. When the battery reaches 0.5A, charge it at 1-2C. When the battery reaches 7A, charge it at 0.5C until it is fully charged. 2. When the light intensity is low, if the battery is fully charged, the battery will be slowly charged at 0.5C until it is fully charged. When the battery is low, the fog light enters low power mode and the battery will be slowly charged at 0.2C. When the battery reaches 0.5A, it will be charged at 1-2C. When the battery reaches 7A, it will be charged at 0.5C until it is fully charged.

[0143] In this way, the above system manages battery charging and power supply to the light panels, maximizing energy utilization. Under the same operating parameters, the required battery capacity and solar panel size are smaller, and the battery life is increased by approximately 30%.
