Description

Technical Field

[0001] This utility model relates to the field of road warning device technology, and in particular to a cellular device for traffic information display boards. Background Technology

[0002] With the continuous advancement of my country's transportation infrastructure construction, the functions and types of road warning devices are also constantly developing and improving. Various road warning devices and traffic facilities play an important role in ensuring traffic safety. Among them, traffic information display boards can provide traffic participants with timely dynamic or static warning information in road warning scenarios, and are the main medium for the road warning system to function.

[0003] Currently, existing traffic information display devices mainly include the following types: static non-actively luminous information display boards, which usually have fixed graphic symbols or text information drawn on the display panel (generally made of metal), such as road signs; these information display boards inherently have the disadvantages of displaying information that cannot be changed and being unclear under poor lighting conditions;

[0004] Static active-illuminated information displays typically add an LED matrix to the information displayed on static, non-active-illuminated displays, enhancing the displayed information in low-light conditions. While this type of display overcomes the problem of unclear display in poor lighting, it still suffers from the drawback of fixed information display; the display cannot be adjusted as needed. Furthermore, these displays often have exposed light-emitting components, making them susceptible to damage in harsh weather conditions such as sandstorms and acid rain. The LEDs are also prone to short circuits due to moisture.

[0005] Dynamic active-emitting information display boards, commonly seen in the market as LED information displays, use a full-matrix array to display various information, including static and dynamic information. They are actively emitting light, displaying on demand, and highly automated, overcoming the shortcomings of the previous two types of devices. However, LED information displays have high manufacturing and power consumption costs, resulting in significant construction and operating costs. Furthermore, they have a high failure rate; the warranty period for most LED information displays on the market is only one year, and when a failure occurs, the entire faulty screen often needs to be replaced, leading to substantial maintenance costs. Especially in complex weather and electromagnetic environments such as high temperatures, humidity, rain, and lightning, the aging and failure rate of LED information displays is accelerated.

[0006] Therefore, it is necessary to design an inexpensive and durable illuminated information display board, while also avoiding the problem of excessive power consumption. Utility Model Content

[0013] The first support base (B222) is made of insulating plastic and is X-shaped. Its size is adapted to the inner side of the second honeycomb cell (B200) so that it can be fixed by being secured at the four inner corners of the second honeycomb cell (B200). The second support base (B322) is also made of insulating plastic and is X-shaped. The partition baffle (B330) is made of insulating plastic and is rectangular.

[0028] Currently, existing traffic information display devices mainly include the following types:

[0029] Static, non-actively illuminated information displays typically feature fixed graphic symbols or text information painted on a display panel (usually made of metal), such as road signs. These devices are simple in structure, low in cost, and easy to install, but they also have significant drawbacks. The main drawbacks are that the displayed content is completely fixed, limiting the types of situations they can handle, and the inability to determine whether to display information on demand. Furthermore, they cannot hide information when it is not needed, potentially misleading the audience. Additionally, their visibility is poor in low-light conditions (such as inclement weather or at night), resulting in limited information delivery capabilities.

[0030] Static active-illuminated information displays typically add an LED matrix to the information displayed on static non-active-illuminated displays to enhance the information display in low-light conditions, thus improving information visibility. However, they still suffer from the drawbacks of fixed information display, limited adaptability, and inability to adjust information display as needed. Therefore, neither static non-active-illuminated nor static active-illuminated information displays are effectively suited for scenarios requiring information content switching. Furthermore, these static active-illuminated displays are primarily modified from existing traffic information signs, often resulting in exposed light-emitting components that are susceptible to damage in harsh weather conditions such as sandstorms and acid rain. The LEDs are also prone to short circuits due to moisture.

[0031] Therefore, relatively high-tech solutions have also been developed, such as dynamic active light-emitting information display boards. The most common form of this device on the market is the LED information display screen. This device can display a variety of information, including static or dynamic information, through a full dot matrix method. It actively emits light and displays on demand, overcoming the shortcomings of the previous two methods. However, due to its inherent physical and electrical characteristics, it has the following inherent disadvantages: 1> High power consumption and high cost. Because it adopts a full dot matrix method, compared with static active-emitting information display boards, this device consumes more power and costs more. Especially in situations requiring large-size display boards, power consumption and cost will increase further. In some scenarios where it is inconvenient to obtain power, the applicability of this device will be limited; 2> Usually, in order to improve the degree of automation, it is also necessary to design corresponding display control programs. Therefore, it is necessary to set up corresponding control and communication systems. Although the degree of automation is high, there are also problems such as easy damage and high construction and operation costs; 3> Because it adopts a full dot matrix method, the number of light-emitting pixels in the dot matrix is ​​much greater than the number of LED beads on a static active-emitting information display board. Thus, the probability of producing defective pixels is much greater than the probability of LED beads on a static active-emitting information display board being damaged. Moreover, when defective pixels occur, the entire LED bead needs to be replaced, resulting in high maintenance costs. Therefore, although dynamic active luminous information displays are highly automated and can be remotely operated to meet the needs of information content switching, they also have problems such as high construction costs and the interactive control system being prone to failure, which affects their use. In particular, in some complex electromagnetic environments, the interactive control system that is connected to the dynamic active luminous information display may experience downtime or failure.

[0032] To address the problems of existing information display devices, it is necessary to provide a new information display device that can actively emit light, determine whether to display information on demand, completely hide information when it is not needed to avoid misleading the audience, display predetermined dynamic information, and has ultra-low power consumption, ultra-low cost, and convenient and low maintenance costs.
