Description

Technical Field

[0001] This application relates to the field of traffic safety technology, and in particular to a traffic warning device. Background Technology

[0002] Traffic warning devices are equipment used to issue safety reminders, prompts, or warnings to road users along the roadside. They are usually installed on both sides of the road, at intersections, or in construction zones, and use voice or sound to alert passing vehicles and pedestrians to traffic conditions in order to reduce the incidence of traffic accidents.

[0003] However, the sound coverage of current traffic warning devices is limited, resulting in limited warning effectiveness and failing to meet the needs of long-distance warning. For example, most current traffic warning devices use a single loudspeaker (horn). Due to the single-direction sound emission, the sound field coverage is limited. In road areas that are far from the main radiation direction of the loudspeaker, the sound signal is prone to significant attenuation, creating blind spots for safety warnings.

[0004] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0005] In view of the above problems, this utility model proposes a traffic warning device, which aims to solve the technical problem that the limited sound coverage of traffic warning devices leads to limited warning effects.

[0006] To achieve the above objectives, the traffic warning device proposed in this utility model includes a housing and two sound-generating components. The housing includes a mounting back plate and two side plates, the two side plates being connected to both sides of the mounting back plate in the lateral direction, and the two side plates gradually converging along the side away from the mounting back plate; each of the two side plates has a mounting window. Both sound-generating components are placed within the cavity of the housing. Each sound-generating component includes a loudspeaker and a sound-amplifying cover, with part of the loudspeaker inserted into the sound-amplifying cover. The sound-amplifying cover is connected to and exposed through the mounting window, such that the sound output direction of the two sound-generating components is set at an angle to the mounting back plate and is away from the mounting back plate.

[0007] Furthermore, the angle between the sound-emitting component's sound-emitting direction and the mounting backplate is greater than or equal to 10 degrees and less than or equal to 30 degrees.

[0008] In one embodiment, the housing further includes a front side plate that is parallel to and spaced apart from the mounting back plate, wherein the two ends of the front side plate in the lateral direction are respectively connected to the side of the two side plates away from the mounting back plate; Both the loudspeaker cover and the front side panel extend vertically in a long strip shape; The distance between the front side panel and the mounting back panel is less than the length of the front side panel.

[0009] Furthermore, the housing includes a box body and a cover body; the box body has an upward-opening mounting cavity; the cover body closes the opening; The housing includes a bottom plate, a mounting back plate connected to the edge of the bottom plate, two side plates, and a front side plate; the bottom plate, the mounting back plate, the two side plates, and the front side plate enclose the mounting cavity.

[0010] Furthermore, the cover extends beyond the outer wall surface of the side plate in the lateral direction.

[0011] Furthermore, the cover body is provided with a receiving groove, and the top of the box body is located in the receiving groove; the peripheral side wall of the receiving groove is provided with a support groove; The traffic warning device also includes two fixing members respectively provided for the two side plates. The fixing members include a first plate and a second plate connected to each other. The first plate extends toward the mounting groove, and the second plate extends toward the vertical direction. The first plate is attached to the inner wall of the support groove, and the second plate is fixedly connected to the side plate.

[0012] In one embodiment, the traffic warning device includes a mounting base, and the housing is rotatably connected to the mounting base.

[0013] Furthermore, the traffic warning device also includes a locking element; The housing is provided with a first mounting hole, and the mounting base is provided with a second mounting hole corresponding to the first mounting hole. The second mounting hole extends around the rotation axis of the housing. The locking member passes through the first mounting hole and the second mounting hole. The locking member has a locking position that fixes the base plate and the mounting base and an adjusting position that can slide along the second mounting hole.

[0014] Furthermore, the mounting base includes a mounting cylinder for mounting on a ground support and a mounting plate fixedly connected to the top of the mounting cylinder; The mounting plate is provided with a first wire-passing hole in the area corresponding to the inner cavity of the mounting cylinder; the housing is provided with a second wire-passing hole in the area corresponding to the first wire-passing hole, and the first wire-passing hole and the second wire-passing hole connect the mounting cavity and the inner cavity of the mounting cylinder; The mounting plate has a second mounting hole in the area extending beyond the outer wall of the mounting cylinder.

[0015] In one embodiment, the outer wall surface of the mounting back plate is provided with a mounting portion.

[0016] This utility model traffic warning device installs sound-emitting components on the mounting windows on both sides of the housing. The sound emission direction of each component forms a preset angle with the mounting back plate and is set away from each other. This spatially separates the main sound radiation areas of the two sound-emitting components and directs them toward the oblique areas at both ends, thereby expanding the overall sound coverage of the device. This avoids the phenomenon of limited sound coverage caused by a single sound-emitting component or two parallel sound-emitting components and improves the warning effectiveness of the traffic warning device.

[0024] This utility model proposes a traffic warning device 100.

[0025] In this embodiment of the utility model, please refer to Figures 1 to 8 The traffic warning device 100 includes a housing 10 and two sound-generating components 20. The housing 10 includes a mounting back plate 11 and two side plates 121. The two side plates 121 are connected to the two sides of the mounting back plate 11 in the lateral direction, and the two side plates 121 gradually move closer together along the side away from the mounting back plate 11. Each side plate 121 has a mounting window 1211. Both sound-generating components 20 are placed inside the cavity of the housing 10. Each sound-generating component 20 includes a loudspeaker 21 and a sound-amplifying cover 22. Part of the loudspeaker 21 is inserted into the sound-amplifying cover 22. The sound-amplifying cover 22 is connected to and exposed in the mounting window 1211 so that the sound output direction of the two sound-generating components 20 is set at an angle to the mounting back plate 11 and is away from the mounting back plate 11.

[0026] The housing 10 serves as the load-bearing and protective structure for the entire device, used to fix the sound-generating component 20 and protect the internal components from dust, rain, and external impacts.

[0027] The housing 10 includes a mounting back plate 11 and two side plates 121. The mounting back plate 11 provides a mounting surface for fixing to external poles, walls, or road structures. The side plates 121 are located on both sides of the mounting back plate 11, and their function is to define the shape of the housing 10 and provide mounting windows 1211 for the sound-generating assembly 20. The mounting back plate 11 can be rectangular, trapezoidal, curved, etc., and is not limited thereto. The side plates 121 can be flat, curved, or have reinforcing ribs, etc. The side plates 121 and the back plate can be connected by welding, screws, rivets, or integral molding, etc. Specifically, for example, by bending sheet metal.

[0028] The mounting window 1211 provides space for the loudspeaker cover 22 to protrude from the housing 10, allowing sound to travel from inside the housing 10. Furthermore, the exposed loudspeaker cover 22 can directly transmit sound to the target area, reducing reflection loss from the housing 10. The two side plates 121 gradually converge along the side away from the mounting back plate 11. Based on this, the loudspeaker cover 22 is fitted and installed in the mounting window 1211, causing the sound from the sound-generating component 20 to be deflected towards both sides of the road due to the position of the side plates 121. The loudspeaker cover 22 can be fixedly connected to the mounting window 1211 by means of snaps, threads, adhesives, etc. In some embodiments, the edge of the loudspeaker cover 22 has a periphery that is bent relative to the main body. During installation, the loudspeaker cover 22 is placed inside the housing 10 from the mounting window 1211, and the periphery forms a limit with the side plates 121. Screws are used to fix the periphery to the limiting plate to achieve the installation of the sound-generating component 20.

[0029] The sound-generating component 20 generates and amplifies sound signals to provide traffic warnings. It includes a loudspeaker 21 and a loudspeaker enclosure 22. The loudspeaker 21 converts electrical signals into sound waves. The loudspeaker enclosure 22 is fitted over the front of the loudspeaker 21 and functions to concentrate and guide the sound waves, reducing sound energy loss. Part of the loudspeaker 21 is inserted inside the loudspeaker enclosure 22, which reduces sound wave leakage, improves low-frequency sound transmission, and facilitates fixation. The loudspeaker enclosure 22 can be conical, horn-shaped, etc.

[0030] The sound emission directions of both sound-emitting components 20 are set at a preset angle to the mounting back plate 11, and are opposite to each other. In this way, based on the directivity principle of the loudspeaker 21, the main sound radiation direction of each sound-emitting component 20 extends outward from the mounting back plate 11. By adjusting the angle between the sound emission direction and the mounting back plate 11, the main sound radiation areas of the two sound-emitting components 20 are spatially separated, thereby covering different road areas at the installation location respectively.

[0031] It is understandable that the sound output direction is the direction of the central axis of the sound-emitting assembly 20 (the speaker 21 and the speaker enclosure 22 are usually coaxial).

[0032] Specifically, when the device is installed on one side of the road, the main sound radiation direction of one sound-emitting component 20 can point to the front section of the road, and the main sound radiation direction of the other sound-emitting component 20 can point to the rear section of the road. Because the sound emission directions of the two components are not parallel but at a certain angle, the total effective sound field angle can be significantly increased, resulting in a significantly improved warning coverage compared to a single loudspeaker 21 or speakers 21 arranged in the same direction. For example, in areas to the side where a single loudspeaker 21 cannot effectively cover; when the main radiation directions of two parallel loudspeakers 21 are pointed in the same direction, the sound energy is concentrated in the same narrow area (directly in front), resulting in blind spots with insufficient volume in the lateral or obliquely forward areas. In this embodiment, because the spatial distribution of the two sound-emitting components 20 is complementary, sufficient sound energy can be obtained in areas to the side where a single loudspeaker 21 cannot effectively cover, thereby expanding the sound coverage range.

[0033] Based on the above, the two sound-emitting components 20 being positioned opposite the mounting backplate 11 can avoid wasting sound energy. Positioning the sound output opposite the mounting backplate 11 directs the sound energy directly towards the road and the area where traffic participants are located, reducing ineffective radiation and reflection losses of sound inside the housing 10 or behind the backplate, thereby improving sound energy utilization.

[0034] The traffic warning device 100 of this utility model installs the sound-emitting components 20 on the mounting windows 1211 on both sides of the housing 10. The sound emission direction of each component is at a preset angle to the mounting back plate 11 and is set away from each other. This makes the main sound radiation areas of the two sound-emitting components 20 spatially separated and facing the oblique areas at both ends, thereby expanding the overall sound coverage of the device. This avoids the phenomenon of limited sound coverage caused by a single sound-emitting component 20 or two parallel sound-emitting components 20, and improves the warning effectiveness of the traffic warning device 100.

[0035] Furthermore, the angle between the sound-emitting component 20 and the mounting backplate 11 is greater than or equal to 10 degrees and less than or equal to 30 degrees. In this embodiment, the angle between the sound-emitting component 20 and the mounting backplate 11 can be 10 degrees, 13 degrees, 15 degrees, 20 degrees, 24 degrees, 27 degrees, and 30 degrees, etc. If the angle between the sound-emitting component 20 and the mounting backplate 11 is less than 10 degrees, although a wider angle can be covered, the sound pressure in the central front area may decrease, forming a blind spot in the middle. If the angle between the sound-emitting component 20 and the mounting backplate 11 is greater than 30 degrees, the overlap of the coverage areas of the two sound-emitting components 20 is high, and the increase in coverage width is limited, resulting in only some lateral areas of the traffic warning device being able to hear the sound. In this embodiment, the angle between the sound-emitting component 20 and the mounting backplate 11 is greater than or equal to 10 degrees and less than or equal to 30 degrees. In this way, the radiation areas of the two sound-generating components 20 can be fully separated, increasing the lateral sound field, while also ensuring that there is still some overlap between the sound fields of the two sound-generating components 20, so as to ensure that the sound in the central road section is not significantly reduced and to avoid blind spots.

[0036] In one embodiment, the housing 10 further includes a front side plate 122 that is parallel to and spaced apart from the mounting back plate 11. The two ends of the front side plate 122 are respectively connected to the side of the two side plates 121 away from the mounting back plate 11 in the lateral direction. The speaker cover 22 and the front side plate 122 both extend in the vertical direction in the shape of a long strip. The distance between the front side plate 122 and the mounting back plate 11 is less than the length of the front side plate 122.

[0037] In this embodiment, the front side plate 122 serves as a lateral connecting member between the side plates 121. On one hand, it can act as a guiding edge for some sound waves, reducing sound wave leakage or diffraction in non-predetermined directions and helping to concentrate sound energy in the direction of sound output from the amplifier cover 22. On the other hand, it can improve the overall rigidity and deformation resistance of the housing 10. The front side plate 122 and the side plates 121 can be welded, bolted, riveted, or integrally formed, etc., and are not limited here.

[0038] The front side panel 122 and the mounting back panel 11 are arranged parallel to each other and spaced apart, and together with the side panel 121, they form the cavity of the housing 10 to accommodate the sound-generating assembly 20. Furthermore, compared to the two side panels 121 being connected at the ends furthest from the mounting back panel 11, this embodiment has a smaller volume, achieving a compact overall structure. The distance between the front side panel 122 and the mounting back panel 11 being less than the length of the front side panel 122 also contributes to the compactness of the overall structure. In some cases, markings can also be provided on the front side panel 122 for a warning purpose.

[0039] Traffic warning devices 100 are often installed on roadside poles. In order to cover pedestrians and vehicles, sound waves need to be propagated evenly in the vertical range. The loudspeaker cover 22 and the front side plate 122 both extend vertically in a long strip shape, which can generate a nearly uniform sound pressure distribution in the near field area and match the structure of the electroacoustic unit to reduce ineffective radiation.

[0040] Understandably, the opening of the loudspeaker 22 extends vertically in a long, narrow shape. When sound waves emerge from this long, vertical opening, it is easier to create a wider coverage area in the vertical direction (up and down). Compared to a square or a wider rectangle, this vertically elongated opening design helps the sound spread vertically without dispersing too quickly to the left or right. In other words, due to the structure of the loudspeaker, the sound can cover a wider area in the vertical direction (up and down) (such as from above the listener's head to the ground in front); in the horizontal direction (left and right), the sound is relatively more concentrated, avoiding unnecessary interference to adjacent areas.

[0041] Furthermore, the housing 10 includes a box body 12 and a cover body 13; the box body 12 has a mounting cavity 124 with an opening 125 facing upward; the cover body 13 covers the opening 125; the box body 12 includes a bottom plate 123 and a mounting back plate 11, two side plates 121 and a front side plate 122 connected to the edge of the bottom plate 123; the bottom plate 123, the mounting back plate 11, the two side plates 121 and the front side plate 122 enclose to form the mounting cavity 124.

[0042] In this embodiment, the enclosure 12 is the main structure of the shell 10, forming a mounting cavity 124 with an upper opening 125 for accommodating the sound-generating component 20 and related circuit systems. The bottom plate 123, the mounting back plate 11, the two side plates 121, and the front side plate 122 together form the enclosure 12, providing multi-faceted enclosed protection for the internal components and preventing the intrusion of external environmental factors (rainwater, dust, gravel).

[0043] The cover 13 fits over the opening 125 of the enclosure 12, effectively preventing moisture, fallen leaves, and other contaminants from entering the mounting cavity 124. Simultaneously, the cover 13 is detachable or can be flipped open, facilitating maintenance and replacement of the internal sound-generating components 20 and wiring. The cover 13 can be designed as a flat plate, arched, or rainproof eaves, and can be made of metal or engineering plastic; its specific shape and material are not limited here. The cover 13 can be connected to either side panel 121 via hinges to form a flip-top structure; it can also be fixed to the top of the enclosure 12 with bolts to form a fully detachable cover.

[0044] In this embodiment, the opening 125 of the box 12 faces upward, but after being equipped with the cover 13, the internal structure can be physically protected in all aspects, especially improving the waterproof and dustproof level in outdoor environments.

[0045] Furthermore, the cover 13 extends laterally beyond the outer wall of the side panel 121. When the conventional cover 13 is flush with the edge of the side panel 121, its protective range is limited to the projected area of ​​the housing 10, and it cannot completely block rainwater, dust, and sunlight entering from an angle. In this embodiment, however, the cover 13, extending beyond the outer wall of the side panel 121, forms a larger shaded area, protecting the side panel 121, the front side panel 122, and the speaker grille 22, reducing the direct impact of external environmental factors on these components. It is understood that this embodiment can reduce the accumulation of dirt on the surface of the speaker 21 through the protection of the cover 13, maintaining a stable sound transmission effect over a long period. In some embodiments, the protruding portion of the cover 13 may adopt a horizontal extension or a structure with a downward slope, which can guide rainwater to drain along the outside, preventing water accumulation and pressure on the cover 13. In some embodiments, the cover 13 extends beyond the peripheral side wall of the housing 12.

[0046] Furthermore, the cover 13 is provided with a receiving groove 131, and the top of the box 12 is located in the receiving groove 131; the peripheral side wall of the receiving groove 131 is provided with a resting groove 132; the traffic warning device 100 also includes two fixing members 30 respectively provided corresponding to the two side plates 121. The fixing member 30 includes a first plate 31 and a second plate 32 connected to each other. The first plate 31 extends toward the resting groove 132, and the second plate 32 extends in the vertical direction; the first plate 31 is hung on the inner wall of the resting groove 132, and the second plate 32 is fixedly connected to the side plate 121.

[0047] In this embodiment, the cover 13 has a receiving groove 131 for covering and fixing the top of the box 12, so that the top of the box 12 is embedded therein, which greatly improves the overall stability and sealing of the device after the top is assembled. This embedded structure is more resistant to wind pressure and vibration than a simple covering structure, making the traffic warning device 100 more stable in outdoor environments.

[0048] The support groove 132 is provided on the peripheral side wall of the receiving groove 131. Thus, the support groove 132 serves as an installation limiting structure, forming an installation limiting part for mating with the first plate 31 of the fastener 30. Since the support groove 132 is located on the peripheral side wall of the receiving groove 131, during assembly, the first plate 31 can be first hooked onto the inner wall of the support groove 132, and then the second plate 32 can be fixed to the side plate 121.

[0049] The fastener 30 includes a first plate 31 and a second plate 32, which form an L-shape or right angle structure. The first plate 31 extends toward the mounting groove 132 and is used to hang on the inner wall of the mounting groove 132 to achieve structural positioning and suspension connection. The second plate 32 extends vertically and is fixedly connected to the side plate 121 of the housing 10 to achieve vertical fixed support from the cover 13 to the housing 10. The two fasteners 30 are arranged corresponding to the side plates 121 on both sides of the housing 10, so that the cover 13 and the top of the box 12 are stably fixed on both sides in the lateral direction, preventing loosening or tilting on one side.

[0050] In one embodiment, the traffic warning device 100 includes a mounting base 40, to which the housing 10 is rotatably connected.

[0051] In this embodiment, the mounting base 40 serves as the interface between the device and the installation environment (such as streetlight poles, uprights, etc.), ensuring the stable fixation of the entire device. It provides a rotating connection point for the housing 10, allowing the housing 10 to adjust its orientation according to site requirements. Simultaneously, it supports the weight of the housing 10. The rotatable connection between the housing 10 and the mounting base 40 allows the housing 10 to adjust its angle in real time according to road direction, turning radius, special construction areas, etc., thereby changing the direction of sound emission.

[0052] Furthermore, the traffic warning device 100 also includes a locking member; the housing 10 is provided with a first mounting hole 1231, and the mounting base 40 is provided with a second mounting hole 51 corresponding to the first mounting hole 1231, the second mounting hole 51 extending around the rotation axis of the housing 10; the locking member passes through the first mounting hole 1231 and the second mounting hole 51; the locking member has a locking position for fixing the base plate 123 and the mounting base 40 and an adjustable position that can slide along the second mounting hole 51.

[0053] In this embodiment, when the locking member is in the locked position, it fixes the relative positions of the base plate 123 and the mounting base 40 with respect to the housing 10, preventing rotation or loosening. In the "adjustment position," the locking member is allowed to slide along the direction of the second mounting hole 51, thereby allowing the housing 10 to rotate and thus adjusting the angle of the sound output direction of the traffic warning device 100. In this way, the two functions of fixing and adjusting can be switched through simple mechanical operation, facilitating quick installation and adjustment.

[0054] The first mounting hole 1231 can be a round hole, which cooperates with the locking element to achieve rigid positioning. The second mounting hole 51 can be an oblong hole or a strip groove, extending in the same direction as the rotation direction of the housing 10, to facilitate sliding adjustment. This combination of round and oblong holes can ensure that the housing 10 does not rotate or shift when fixed, and can also ensure that the housing 10 slides smoothly and adjusts its angle flexibly when adjusted.

[0055] Furthermore, the mounting base 40 includes a mounting cylinder 41 for mounting on a ground support and a mounting plate 42 fixedly connected to the top of the mounting cylinder 41; the mounting plate 42 is provided with a first wire passage hole 421 in the area corresponding to the inner cavity of the mounting cylinder 41; the housing 10 is provided with a second wire passage hole 14 in the area corresponding to the first wire passage hole 421, the first wire passage hole 421 and the second wire passage hole 14 communicate with the mounting cavity 124 and the inner cavity of the mounting cylinder 41; the area of ​​the mounting plate 42 extending beyond the outer wall of the mounting cylinder 41 is provided with a second mounting hole 51.

[0056] In this embodiment, the mounting cylinder 41 is a connecting component between the traffic warning device 100 and ground supports (such as poles, piles, and guardrail posts), providing vertical support and providing space for wiring. The mounting cylinder 41 can be cylindrical, square, or polygonal, and can be adjusted according to actual needs; its material can be metal (such as stainless steel or aluminum alloy) or engineering plastic.

[0057] Mounting plate 42 is fixed to the top of mounting cylinder 41 and is used to connect to housing 10, achieving stable docking between mounting base 40 and housing 10. The portion of mounting plate 42 extending beyond the outer wall of mounting cylinder 41 has a second mounting hole 51, which can be used for locking components to improve structural stability. Mounting plate 42 can be a circular plate, square plate, or polygonal plate, etc. The connection between mounting plate 42 and mounting cylinder 41 can be welding, integral molding, or bolt connection; no limitation is made here.

[0058] The first cable pass-through hole 421 is located in the area of ​​the mounting plate 42 corresponding to the inner cavity of the mounting cylinder 41, providing a channel for wiring so that the cable can directly enter the mounting cavity 124 of the housing 10 from the inner cavity of the mounting cylinder 41. The second cable pass-through hole 14 is located at the bottom of the housing 10 and corresponds to the first cable pass-through hole 421. It can connect the mounting cavity 124 and the inner cavity of the mounting cylinder 41, ensuring that the wiring is transmitted in a completely enclosed external environment, avoiding rainwater intrusion, ultraviolet aging, or human damage caused by wiring exposure in outdoor environments. The number of the first cable pass-through hole 421 and the second cable pass-through hole 14 can be one or more, and is not limited here.

[0059] In one embodiment, the outer wall of the mounting backplate 11 is provided with a mounting portion 111. In this embodiment, the mounting portion 111 provides a physical connection interface between the traffic warning device 100 and the installation environment, enabling the entire device to be firmly connected to various bases such as poles, walls, and brackets, ensuring stable operation in outdoor wind and rain environments. The mounting portion 111 can be a flange, a slide, a guide rail, or a protruding positioning post, which can be customized according to actual needs and is not limited here. The mounting portion 111 can be adapted to different installation methods, such as bolt fixing, clamp fixing, and slide groove insertion, thereby improving the versatility and multi-scenario applicability of the device.

[0060] The mounting part 111 can be integrally formed with the mounting back plate 11, such as by stamping or casting, to improve the overall structural strength and reduce the number of parts; the mounting part 111 can also be separately connected with the mounting back plate 11, such as by welding or screwing, so that different forms of mounting parts 111 can be flexibly replaced to adapt to various installation environments.

[0061] In some embodiments, a strobe light 63 may be provided on the side plate 121. Further, a strobe light 63 may be provided at the upper and lower ends of the mounting window 1211 respectively.

[0062] In some embodiments, the traffic warning device 100 further includes a gasket 62 disposed within the mounting cavity 124. The gasket 62 is fixedly connected to the base plate 123 and the mounting plate 42 to enhance the connection between the base plate 123 and the mounting plate 42. The gasket 62 is also provided with a clearance hole connecting the first wire passage hole 421 and the second wire passage hole 14 for the cable to pass through.

[0063] In some embodiments, the cover 13 may also be equipped with radar, temperature detection device, weather feedback module, etc. In some embodiments, the cover 13 is provided with several mounting holes for installation. The traffic warning device 100 also includes several plugs. When the mounting holes are not used, the plugs can be used to seal the mounting holes to prevent external rainwater, debris, etc., from entering the housing 10 through the mounting holes.

[0064] In some embodiments, several of the aforementioned traffic warning devices can form a rapid sound field intervention system. Specifically, in the direction of road extension, adjacent traffic warning devices are spaced apart and located on both sides of the road. For example, the first traffic warning device is located on the left side of the road, the second traffic warning device is located on the right side of the road, the third traffic warning device is located on the left side of the road, and so on, with adjacent traffic warning devices being equidistant in the direction of road extension.

[0065] The sound field rapid intervention system has multiple application scenarios. For example, in daily traffic safety warnings, a cloud server controls and issues commands to one or more traffic warning devices, playing predetermined instructions—maintain a safe distance and drive cautiously. Another example is fatigue driving warnings, where a group or area is selected during peak fatigue times (noon or early morning) to play anti-fatigue driving music (music or gentle reminder voice messages). Alternatively, upon discovering an accident, the nearest device is activated, playing pre-programmed music or issuing on-site announcements to quickly intervene at the accident scene (vehicles can move, evacuate; people are not injured, evacuate), ensuring the fastest possible response. Simultaneously, devices within 1-2 km of the accident scene in the direction of oncoming traffic are activated to play music (accident ahead, please slow down). In rainy weather, all devices on a section of road can be selected to play music, creating a sound field to provide safety reminders and warnings to passing vehicles.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
