[0029] In order to better understand the present invention, the present invention will be described in detail below in conjunction with specific embodiments.
[0030] Example 1
[0031] like Figure 1 As shown, a highway interchange ramp merge and divergence guidance system includes a plurality of LED guidance lights 1. The main body of the LED guidance lights 1 is embedded in the road surface, and the height of the upper surface protruding from the road surface is not more than 5mm;
[0032] For the interchange ramp diversion area of the expressway, the LED guide lights 1 are arranged at intervals outside the right solid line of the main road within a distance of at least L1 before the gradient section; the LED guide lights 1 are arranged at intervals outside the right solid line of the gradient section; on the ramp section, the LED guide lights 1 are arranged at intervals outside the left and right solid lines of the ramp, and no less than N1 LED guide lights 1 are arranged on a single side of the ramp; and no less than N2 LED guide lights 1 are arranged at intervals outside the right solid line of the main road after the gradient section.
[0033] For the merging area of the interchange ramp of the expressway, the LED guide lights 1 are arranged at intervals outside the right solid line of the main road within a distance of at least L1 before the gradient section; on the ramp section, the LED guide lights 1 are arranged at intervals outside the left and right solid lines of the ramp, and the arrangement distance is not less than L2; on the outside the right solid line of the gradient section, the LED guide lights 1 are arranged at intervals; on the outside the right solid line of the main road after the gradient section, no less than N2 LED guide lights 1 are arranged at intervals.
[0034] Specifically, for the highway interchange ramp diversion area, such as Figure 1 As shown in the figure, the part between the red dotted line A and the red dotted line B represents the gradient section of the diversion area. In the gradient section, vehicles about to exit the highway need to change lanes to the right to enter the exit ramp. If you fail to change lanes to the right in time in the gradient section, you will miss the ramp entrance and will not be able to exit the highway. For drivers who have a fluke mentality and a weak sense of safe driving, they are likely to run over the guide line to enter the ramp, and running over the guide line to enter the ramp will affect the normal driving of the rear vehicles, and in serious cases will cause traffic accidents. In order to guide drivers who are about to exit the highway to change lanes in time and avoid the guide line, as shown in the figure, Figure 1As shown, (1) the LED induction lights are arranged at intervals outside the right solid line of the main road within a distance of at least L1 before the gradient section (the section that the vehicle passes first is regarded as the front); the LED induction lights are arranged on this section to remind the driver that the highway can be exited ahead, and the driver who needs to exit is reminded to drive close to the right LED induction lights; (2) the LED induction lights are arranged at intervals outside the right solid line of the gradient section; because the driver has been induced to drive close to the right LED induction lights before the gradient section, the driver only needs to continue to drive close to the right LED induction lights on the gradient section to be able to exit in time. Entering and exiting the ramp, thereby avoiding missing the exit; (3) On the ramp section, the LED guide lights are arranged at intervals outside the left and right solid lines of the ramp, and no less than N1 LED guide lights are arranged on one side of the ramp; thereby, the driver exiting the expressway can be further guided to enter the ramp; (4) After the gradient section (the section after the vehicle passes is the rear), no less than N2 LED guide lights are arranged at intervals outside the right solid line of the main road; the LED guide lights on this section and the LED guide lights outside the left solid line of the ramp outline the shape of the guide line, which can remind the driver that there is a guide line ahead and he needs to pay attention to avoid it.
[0035] More specifically, for the merging area of the highway interchange ramp, such as Figure 2 As shown in the figure, the part between the red dotted line C and the red dotted line D represents the gradient section of the merging area. In the gradient section, vehicles about to enter the expressway need to speed up and change lanes to the left to merge into the main road. Changing lanes to the left in advance will cause the guide line to be crushed and may conflict with the vehicle behind. Delaying the left lane change will result in not being able to merge into the main road in time and driving in the emergency lane. At the same time, ramp vehicles should pay attention to avoid vehicles coming from the main road in the gradient section, and vehicles on the main road should pay attention to avoid vehicles coming from the ramp in the gradient section. In order to guide the vehicles in the interchange ramp merging area to drive safely, such as Figure 2As shown, (1) the LED induction lights are arranged at intervals on the outside of the right solid line of the main road within a distance of at least L1 before the gradient section (the section that the vehicle passes first is the front); the LED induction lights are arranged through this section to remind the main road driver that there is a vehicle merging in front and to pay attention to avoid it; (2) on the ramp section, the LED induction lights are arranged at intervals on the outside of the left and right solid lines of the ramp, and the arrangement distance is not less than L2; the LED induction lights are arranged through this section to remind the ramp driver that he is about to merge into the main road; and the LED induction lights on the outside of the left solid line of this section The LED induction lights set before the gradient section can outline the shape of the guide line, thereby reminding the driver to pay attention to avoid it; (3) The LED induction lights are set at intervals outside the solid line on the right side of the gradient section; thus, the ramp driver can merge into the main road in time as long as he drives close to the right LED induction lights; (4) After the gradient section (the section after the vehicle passes is the rear), no less than N2 LED induction lights are set at intervals outside the solid line on the right side of the main road; vehicles that have just merged into the main road can be further guided to continue driving along the main road. In this embodiment, it is preferred that Figure 2 As shown, for the interchange ramp merging area of the expressway, at each solid line position before the gradient section, at least five LED induction lights closest to the gradient section are set as red LED induction lights.
[0036] It is further preferred in this embodiment that the value of L1 is 210m, the value of L2 is 150m, the value of N1 is 5, and the value of N2 is 5.
[0037] It should be noted that the interval between adjacent LED induction lights outside the same solid line is set to 8 to 15 meters, and preferably they are set at equal intervals.
[0038] Example 2
[0039] This embodiment is similar to the above embodiment, except that, in this embodiment, a preferred structure of the LED induction lamp is described.
[0040] like Figure 4 and Figure 5As shown, the LED induction light includes an upper housing 10 and a lower housing 20. The bottom surface 106 of the upper housing 10 is made of elastic material, and an elastic pressure sensor 105 is disposed on the upper surface of the bottom surface 106 of the upper housing 10. The lower portion of the upper housing 10 is inserted into the lower housing 20, and an elastic filler is disposed between the bottom surfaces 106 of the upper housing 10 and the bottom surfaces of the lower housing 20. A solar panel 101, a storage battery 108, a control circuit board 104, and LED lamp beads 102 are disposed within the upper housing 10. The solar panel 101 faces upward, the control circuit board 104 is disposed below the solar panel 101, the storage battery 108 is disposed below the control circuit board 104, and the LED lamp beads 102 are disposed on opposite sides of the solar panel 101. The solar panel 101, the storage battery 108, and the LED lamp beads 102 are all electrically connected to the control circuit board 104. The elastic pressure sensor 105 is disposed below the control circuit board 104 and is electrically connected to the control circuit board 104. A light sensor 103 is also disposed in the upper housing 10 and is electrically connected to the control circuit board 104.
[0041] Specifically, in this embodiment, it is preferred that Figure 3 As shown, the LED induction lamp is cylindrical in shape and comprises an upper shell 10 and a lower shell 20. The lower portion of the upper shell 10 is sheathed in the lower shell 20. Figure 4As shown, ribs 1010 are spaced apart on the outer circumference of the upper surface of the upper shell 10; a light-transmitting material 109 is disposed within the outer circumference of the upper surface. The light-transmitting material 109 allows sunlight to shine on the solar panel 101, and light from the LED lamp beads 102 can be emitted from the LED induction light. The ribs 1010 prevent the transparent material 109 from being crushed by vehicle tires, thereby protecting the LED induction light. Further preferably, the upper shell 10, except for the light-transmitting material 109 and its bottom surface 106, is made of a rigid material; the light-transmitting material 109 is made of tempered glass, acrylic, or the like. The inner wall of the upper housing 10 is provided with two bosses, and the bottom of a mounting bracket 107 with a trapezoidal cross-section is mounted on each of the bosses. The upper surface of the mounting bracket 107 is used to mount the solar panels 101. Two groups of solar panels 101 are provided. A light sensor 103 is installed on the upper surface of the mounting bracket 107 between the two groups of solar panels 101. The LED lamp beads 102 are mounted on both sides of the mounting bracket 107. The LED lamp beads 102 are installed in an array on the two sides of the mounting bracket 107. The angle of inclination of the two sides of the mounting bracket 107 allows the light emitted by the LED lamp beads 102 to pass through the light-transmitting material 109, exit the LED guidance light, and enter the driver's eyes. As a further preferred embodiment, the outer circumference of the upper surface of the upper housing 10 is not provided with ribs 1010 in the direction of light emitted by the LED lamp beads 102. The lower surface of the mounting bracket 107 is provided with multiple protrusions, to which the control circuit board 104 is fixedly connected and positioned below the mounting bracket 107. These protrusions create a space between the control circuit board 104 and the mounting bracket 107, allowing for the placement of certain electronic components on the upper surface of the control circuit board 104 and improving heat dissipation efficiency. The energy storage battery 108 is positioned below the control circuit board 104 and on the bottom surface 106 of the upper housing 10.
[0042] The bottom surface 106 of the upper housing 10 is made of an elastic material, and an elastic filler is provided between the bottom surface 106 of the upper housing 10 and the bottom surface of the lower housing 20. When a vehicle runs over the LED guidance light, this cushions the vehicle's rolling force while causing a change in the value detected by the elastic pressure sensor 105. This provides data support for expanding the functionality of the highway interchange ramp merge and diverge guidance system.
[0043] The light sensor 103 can collect the current ambient light intensity and send the collected ambient light intensity to the control circuit board 104. The control circuit board 104 can adjust the brightness, frequency, duty cycle, lighting mode, etc. of the LED lamp bead 102 according to the current ambient light intensity.
[0044] Example 3
[0045] This embodiment is similar to the above embodiment, except that, in this embodiment, it is preferred that Figure 3 As shown, the highway interchange ramp diverging and merging guidance system also includes an edge base station 2 and a server 3. The LED guidance light 1 is connected to the server 3 via its built-in LoRa communication module 1041 and the edge base station 2 to send collected data to the server 3 and receive data sent by the server 3. The highway interchange ramp diverging and merging guidance system also includes a meteorological monitoring sensor 4, which is connected to the server 3.
[0046] It should be noted that the edge base station 2 can be connected to the server 3 via Ethernet or 4G / 5G network. Each edge base station 2 can communicate with multiple LED induction lights 1. In the highway interchange ramp merge and diverge induction system, the number of edge base stations 2 is determined by the number of LED induction lights 1. It is necessary to ensure that each LED induction light is connected to one edge base station 2.
[0047] It should be further explained that, since the LED induction light is equipped with an elastic pressure sensor 105, when a vehicle runs over the LED induction light, the LED induction light will transmit the pressure change signal collected by its built-in elastic pressure sensor 105 to the server 3 via the LoRa communication module 1041 and the edge base station 2. This allows back-end management personnel to understand the vehicle traffic conditions in the interchange ramp merge area based on the situation of the LED induction light being run over, providing data support for subsequent determinations on whether to install other electromechanical equipment (such as video surveillance equipment, information boards, etc.) or to judge the rationality of the guide line setting. Simultaneously, the server 3 transmits the meteorological data collected by the meteorological monitoring sensor 4 via the edge base station 2 and the LoRa communication module 1041 to the control circuit board 104 of the LED induction light. The control circuit board 104 controls the brightness, frequency, duty cycle, lighting mode, etc. of the LED lamp beads 102 based on the meteorological data.
[0048] Example 4
[0049] This embodiment is similar to the previous embodiment, except that, in this embodiment, it is preferred that the LoRa communication module 1041 is arranged on the control circuit board 104, and the control circuit board 104 is also provided with an MCU, and the MCU is electrically connected to the LoRa communication module 1041, the LED lamp bead 102, the solar cell panel 101, the energy storage battery 108, the light sensor 103, and the elastic pressure sensor 105.
[0050] In this embodiment, it is further preferred that the model of the LoRa communication module 1041 is RHF0M003, the model of the MCU is FM33LC046N, and the specific circuit structures of the LoRa communication module 1041 and the MCU are as follows: Figure 6 and Figure 7 shown.
[0051] It should be noted that this MCU model supports the expansion of the LED induction light function, such as adding a three-axis geomagnetic sensor and connecting the three-axis geomagnetic sensor to the MCU. The vehicle passage situation is judged by the data collected by the three-axis geomagnetic sensor, and the vehicle passage data is sent to the server through the LoRa communication module 1041. The vehicle traffic situation in the interchange ramp merge area of the highway can be intuitively viewed on the server.
[0052] It should be noted that the technical solutions of this application involve improvements in hardware and do not involve improvements in software; for parts without specified models, they can be selected from commonly used components in the prior art and are not restricted by models; for parts with specified models in the embodiments, they are only used to explain the technical solutions of this application in detail. It should be understood that the technical solutions to be protected by this utility model are not restricted by these models, and there are many options in the prior art to replace these parts.
[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the above embodiments describe the present invention in detail, those skilled in the art should understand that they can modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein, and these replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present invention.
