Description

Technical Field

[0001] The utility model relates to the field of traffic ancillary facilities road marking, in particular to an electronic variable marking system suitable for special-shaped intersections. Background Art

[0002] As urban transportation systems become increasingly complex, due to various factors, including natural constraints, urban planning restrictions, and urban expansion and renewal, special conditions necessitate the design of irregular intersections to accommodate these situations. Irregular intersections are characterized by irregular physical shapes, unsmooth lane configurations, and suboptimal sight distances and visibility. Due to their irregular shapes, limited sight distances, complex traffic flows, and numerous conflict points, traditional road markings struggle to effectively accommodate changing traffic flows, leading to accidents and the occurrence of "wrong-way" traffic. These issues are particularly severe at intersections with a large number of lanes, wide medians, and numerous roads under overpasses. For conventional intersections, guide lines can be added to traditional markings to enhance traffic flow guidance. However, in irregular intersection scenarios, adding guide lines can easily lead to overlapping guide lines, further disrupting traffic flow. Therefore, improving traffic efficiency and ensuring driving safety at irregular intersections remains a pressing challenge. Utility Model Content

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0031] Example 1

[0032] In a typical embodiment of the present application, an electronic variable road marking system suitable for special-shaped intersections is provided, such as Figure 1-5 As shown, it includes a marking display module 1 and a control module 2. The marking display module 1 is installed on the road surface and includes an electronic ink screen 11 for displaying markings and an outer glass plate 13. The electronic ink screen 11 is arranged under the glass plate 13. The glass plate 13 is transparent and at least one surface has anti-slip properties; the control module 2 includes a controller 21 and a remote control center 22. The controller 21 and the remote control center 22 are connected via wireless transmission. The controller 21 is connected to the electronic ink screen 11 to control the color display of the electronic ink screen, thereby forming a road marking guide.

[0033] Specifically, in order to enhance the guidance of traffic flow and improve the traffic efficiency of special-shaped intersections, while avoiding the difficulty of identification and even traffic chaos caused by excessive markings and intersections, this embodiment provides an electronic variable marking system that can display changing guide markings according to the actual traffic conditions of the intersection, such as Figure 1 As shown, the ordinary marking 3 on the original road remains unchanged, and a variable marking system is used for road marking at the special-shaped intersection formed by multiple roads. Only the road markings required at the moment are displayed each time, which is clear and accurate, and can greatly improve the safety and efficiency of traffic at the special-shaped intersection.

[0034] Specifically, if Figure 1 、 2As shown, the electronic variable road marking system of this embodiment includes a road marking display module 1 and a control module 2. The road marking display module 1 includes a glass plate 13 installed on the road surface and an electronic ink screen 11 under the glass plate. The electronic ink screen 11 uses electronic paper display technology (EPD for short) and adopts an EPD display to achieve a road marking display effect by cooperating with other structures; the road marking display module cooperates with the control module to make the electronic ink screen display the road marking color when the road marking needs to be displayed, and to make the electronic ink screen display the road marking color when the road marking does not need to be displayed. In this embodiment, the road marking color is set to white and the road surface color is set to black.

[0035] In this embodiment, the transparent glass plate 13 serves as the road surface directly bearing the traffic and protects the internal electronic ink screen 11. Therefore, it needs to have a certain strength and ensure that the color of the markings displayed on the electronic ink screen can clearly pass through the high-strength glass. At the same time, the surface of the glass plate, especially the side facing the road surface, should have a certain friction coefficient to make it anti-slip, ensuring that vehicles and pedestrians can pass normally on the glass plate. To meet the above requirements, in this embodiment, the glass plate is manufactured using mature processes on the market, such as: using high-strength transparent resin and tempered glass. This technology has been applied in the solar pavement test project laid in Jinan Yinfeng Fortune Plaza and the photovoltaic pavement demonstration project laid on the Jinan Ring Expressway. It can achieve good light transmittance under the conditions of daily driving intensity, ensuring that the markings displayed on the electronic ink screen can be seen by pedestrians and drivers during the day or at night, thereby serving as route instructions.

[0036] Specifically, if Figure 3 As shown, the marking display module 1 also includes a steel frame 14, an LED light 12, and a rechargeable lithium battery 15. The steel frame 14 is installed on the outer layer of the entire module to protect the internal components. The electronic ink screen 11, glass plate 13, and rechargeable lithium battery 15 are all installed within the steel frame 14 and fixedly connected to it.

[0037] like Figure 3 As shown, the LED lamp 12 is fixedly installed on the front side of the electronic ink screen 11, that is, the upward side of the electronic ink screen. When the marking display module needs to display markings at night, the LED lamp provides night lighting, which can make the markings displayed on the electronic ink screen clearer and improve driving safety.

[0038] like Figure 3 As shown, in the marking display module, a rechargeable lithium battery 15 is used to power the entire module. The technology is mature, can maintain the system stable operation for a long time, and is convenient for module integration.

[0039] Specifically, the control module 2 includes a controller 21, a remote control center 22, and a signal controller 23, wherein the controller 21 is installed in the steel structure frame 14 of the road marking display module. In this embodiment, the controller 21 cooperates with the remote control center 22 and the signal controller 23 to establish wireless transmission, and can control the road marking display module according to signal changes to realize variable road markings. Figure 4 As shown, the controller 21 establishes wireless transmission with the remote control center 22 through the signal controller 23, the remote control center 22 is connected to the signal controller 23, the signal controller 23 is connected to the controller 21, and the controller 21 is connected to the electronic ink screen 11 to control the color display of the electronic ink screen, thereby forming an electronic variable road marking guide.

[0040] In this embodiment, signal controller 23 communicates with the remote control center. Remote control center 22 sends intersection signal timing information to signal controller 23, which then transmits the instructions to controller 21, completing the marking color change. The remote control center, serving as the system's hub and connected to the road's traffic light system, can remotely adjust the display timing of signals for each direction. By transmitting the display options for straight or left turn signals to the signal controller, it indirectly transmits the variable marking display options to the controller. If the signal light is red, the controller controls the electronic ink screen to display black; if the signal light is green, the controller controls the electronic ink screen to display white.

[0041] Among them, such as Figure 5 As shown, the controller 21 consists of three parts: a signal input terminal, a control circuit, and a signal output terminal. The signal input terminal, consisting of a signal input terminal and a resistor, is primarily responsible for adjusting the voltage of the input signal. The control circuit is a single-chip microcomputer, which primarily uses a C language program to output corresponding control signals based on green and red light signals. The signal output terminal is primarily responsible for connecting the control circuit to the electronic ink display, allowing the corresponding control signals to be input to the electronic ink display. The controller structure is conventional and can adopt a commonly used mature control module, such as the SWTM-R0416 intelligent lighting time control module, which displays white when the light is green and black when the light is red. The present invention can obtain intersection signal light information through the traffic police control platform, transmit it to the signal controller, and then process it to output the road marking display scheme for the special-shaped intersection to the controller, thereby controlling the variable road marking system. This process is conventional and the signal controller can adopt a commonly used mature product, such as the Hikvision networked traffic signal machine model XHJ-CW-GA-HK344H.

[0042] In the actual layout, the control module 2 is installed under the glass plate 13, and the controller 21 is connected to the electronic ink screen 11 through circuit integration. When the color change of the marking needs to be controlled, the remote control center sends the intersection signal timing information to the signal controller, and then transmits the instruction to the controller to complete the color change of the marking.

[0043] The electronic variable road marking system of this embodiment also includes a new energy power supply module, which is arranged on one side of the road on the road surface and is connected to the controller and rechargeable lithium battery through underground buried lines to provide power for components that require power, such as electronic ink screens and LED lights.

[0044] Specifically, the new energy power supply module is installed on the roadside above the road surface and mainly includes a new energy power generation device, an energy storage device, and a power conversion and distribution device. In this embodiment, the new energy power generation device uses photovoltaic panels to generate direct current through sunlight, which is stored in the energy storage device. The energy storage device then powers the entire system through a rechargeable lithium battery. The energy storage device is connected to the photovoltaic panels. In scenarios where sunlight is insufficient, the energy generated can be stored in the energy storage device to cope with insufficient light energy.

[0045] In addition, in order to ensure the normal use of the system in areas or seasons with insufficient sunlight, the new energy power supply module is also connected to the mains system through a power conversion and distribution device. The power conversion and distribution device is used to distribute the energy supply mode of the mains system and the energy storage device. When the power output of the photovoltaic panel is insufficient, the power conversion and distribution device switches to connect to the mains system for power supply to ensure stable power supply to the rechargeable lithium battery, thereby providing a stable power supply for the electronic variable marking system.

[0046] In this embodiment, the power conversion and distribution device adopts a dual-power automatic transfer switch, for example, the CZQ5-4P / 125A isolated PC-level dual-power automatic transfer switch of Zhongbao Electric Co., Ltd. can be used, which can realize automatic switching between photovoltaic power and city power to ensure continuous and stable power supply.

[0047] In this embodiment, the new energy power supply module can also be combined with the control module and connected to the marking display module through underground buried wires.

[0048] In this embodiment, EPD technology is used to dynamically adjust the display effect of guide lines according to real-time changes in traffic lights, optimize the organization and distribution of traffic flow, ensure the safety of pedestrians and vehicles by accurately guiding traffic flow, reducing conflict points and potential accidents, promote the further development of intelligent transportation technology, and promote the intelligent, information-based and green transformation of the transportation system.

[0049] It should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
