Description

Technical Field

[0001] This utility model belongs to the field of transportation-related technology, specifically relating to an information display system for information boards with a mesh topology structure. Background Technology

[0002] With social development and increasing transportation demands, the need for personalized highway traffic information services is becoming increasingly prominent. Providing personalized traffic information services, such as customized road condition and traffic control information, can offer travelers a more convenient and efficient travel experience.

[0003] Currently, highway operation and management departments typically use information display systems on roads to present real-time traffic and public service information, playing an indispensable role in traffic management and public services. However, most information display systems primarily focus on information management and display, lacking the ability to collect and analyze traffic data. Traditional information displays often use star or bus network connections, but this structure has low fault tolerance and low transmission efficiency. Against this backdrop, this utility model patent proposes a personalized highway traffic information display system based on a mesh network topology. Utility Model Content

[0004] The purpose of this invention is to provide an information display system for information boards with a mesh topology structure that is efficient, accurate, flexible, stable, and highly scalable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mesh topology information display system for information boards, comprising an information acquisition module, a data processing and analysis module, an information display module, a data center, and a remote management terminal. The information acquisition module collects road traffic status information in real time and generates abnormal information when abnormal situations are detected, which is then transmitted and stored in the data center. The data processing and analysis module performs in-depth processing and analysis on the data received from the information acquisition module in the data center to generate the required traffic information. The information display module displays the traffic information to the user. The data processing and analysis module distributes and pushes the required traffic information in a targeted manner according to the installation location and road segment of the information acquisition module. The data processing and analysis module also receives operational status information from the information display module. The data processing and analysis module is also connected to a remote management terminal via a network, which can view the working status, data reception and processing of each information display module in real time and perform remote debugging or data updates.

[0006] As a further improvement of this utility model, the information acquisition module includes a traffic camera, a sensor, a GPS receiver, and supporting acquisition equipment.

[0007] As a further improvement of this utility model, the information acquisition module supports multiple information formats, including text, icons, animated images, and video information.

[0008] As a further improvement of this utility model, the data processing and analysis module includes a data processing server and a network device, wherein the network device utilizes the established network to realize the transmission and interaction of data between the data processing server and external data.

[0009] As a further improvement of this utility model, the information display module displays traffic information to users, including traffic conditions, toll station information, service area information, and event data.

[0010] As a further improvement of this utility model, the information display module consists of two or more variable information boards, which are interconnected by a mesh network topology and achieve efficient interconnection and data sharing between the devices in the variable information board display through a gateway device.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: this technical solution realizes the real-time collection, transmission, and dissemination of traffic information, ensuring the timeliness and accuracy of the information. Based on a network topology, the variable message sign system can display customized information on signs according to different road sections and geographical locations, forming a large-scale information dissemination facility system. The system can also accept and process other data, such as connecting with weather information platforms to obtain weather data from various locations.

[0012] Compared to star or bus topologies, the mesh network topology of this technical solution offers advantages such as higher stability, greater flexibility, and superior performance. In this mesh structure, each node is directly connected to multiple other nodes, ensuring that communication and data transmission can continue even if one node or line fails. This structure guarantees that each information display module can quickly receive the latest traffic information from the data processing and analysis module, and it also enhances the system's fault tolerance, stability, and scalability.

[0013] The mesh structure of this technical solution can flexibly adapt to changes in network size and business requirements. Adding or deleting nodes only requires adjusting the relevant connections, without significantly impacting the overall network. This mesh topology, combined with advanced routing algorithms such as dynamic routing protocols (OSPF and EIGRP), enables intelligent traffic allocation and path optimization.

[0014] This technical solution supports personalized information display at the road network level. The system can provide users with the necessary traffic information services based on the specific conditions of different road sections or geographical locations, combined with historical data and real-time analysis. For example, it can dynamically display real-time traffic conditions (congestion, accidents, construction, etc.), traffic control information, service area information, highway entrance and exit opening and closing information, weather conditions, and even information such as height restrictions, width restrictions, and bridge technical conditions, depending on the road section.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3This utility model provides a technical solution: a mesh topology information display system for information boards, including an information collection module 1, a data processing and analysis module 2, an information display module 3, a data center 4, and a remote management terminal 5. The information collection module 1 collects road traffic status information in real time and generates abnormal information when abnormal situations are detected, which is then transmitted and stored in the data center 4. The data processing and analysis module 2 performs in-depth processing and analysis on the data received from the information collection module 1 in the data center 4 to generate the required traffic information. The information display module 3 displays the traffic information to the user. The data processing and analysis module 2 distributes and pushes the required traffic information in a targeted manner according to the installation location number and road segment of the information collection module 1. The data processing and analysis module 2 also receives the operating status information from the information display module 3. The data processing and analysis module 2 is also connected to the remote management terminal 5 via a network. The remote management terminal 5 can view the working status, data reception and processing of each information display module 3 in real time and perform remote debugging or data updates.

[0021] The information acquisition module 1 includes a traffic camera 11, a sensor 12, a GPS receiver 13, and supporting acquisition equipment 14. The information acquisition module 1 supports various information formats, including text, icons, animated images, and video. The data processing and analysis module 2 includes a data processing server 21 and a network device 22. The network device 22 utilizes the established network to enable the data processing server 21 to transmit and interact with external data.

[0022] The information display module 3 displays traffic information to users, including traffic conditions, toll station information, service area information, and event data. The information display module 3 consists of two or more variable message signs 31, which are interconnected by a mesh network topology and achieve efficient interconnection and data sharing between the devices in the variable message sign display 31 through a gateway device 32.

[0023] The information collection module is the data collection center of intelligent transportation. It includes traffic cameras, sensors, GPS receivers, and other hardware devices such as radar equipment, mounting brackets, and data transmission lines. It is responsible for collecting traffic information and transmitting this information to the data processing and analysis module through wired connections, 4G / 5G cellular networks, or wireless connections on dedicated frequency bands.

[0024] The data processing and analysis module is the computing core of the system, including a data processing server and related network equipment (such as switches). It is responsible for receiving information (road conditions, events, weather, etc.) from the intelligent transportation information collection module, as well as geographic information such as station numbers and road sections from the relevant information sources. It also performs analysis, fusion, and processing operations on different types of data from different sources to generate information about road sections and decision-making information.

[0025] The data processing server employs a CPU processor to meet high computing and parallel processing requirements; it uses a 10G Ethernet interface and is equipped with a PCIe slot to support high-bandwidth data acquisition cards or accelerator cards (such as GPUs, FPGAs, etc.); it is equipped with a high-performance power supply and a UPS uninterruptible power supply system to ensure continuous operation and prevent data loss in the event of a power outage; it uses a Linux operating system and supports common artificial intelligence frameworks (such as TensorFlow and PyTorch) and data processing tools; it supports protocols such as TCP / IP, UDP, Modbus, and MQTT to ensure data transmission with gateways, information boards, and other monitoring systems.

[0026] The information display module is a crucial component of the system, showcasing information to users. It includes variable message signs (VMS) and gateway devices. Gateway devices handle network interconnection, protocol conversion, and data transmission; for example, they calculate the optimal network communication path based on dynamic routing protocols. Network devices are an essential part of the mesh topology and a vital medium for data transmission between the VMS array and the data center. VMS displays feature high-brightness, wide-viewing-angle screens with a resolution of at least 1080P, supporting Ethernet interfaces and wireless transmission (such as WiFi), and are environmentally adaptable, including lightning and moisture resistance. Gateways and other devices utilize embedded Linux systems, enabling continuous 24 / 7 operation. They support 4G / 5G, WiFi, and serial port connections to the VMS, with each gateway equipped with multiple gigabit Ethernet ports. They support various common protocols such as Modbus TCP, UDP, and MQTT, and have at least a dual-core processor for multi-tasking. Through this process, the VMS displays present customized traffic information from the data processing and analysis module to drivers and other users.

[0027] The devices communicate with the network devices and servers of the data processing and analysis module via wired or wireless means through hardware interfaces, sending the collected traffic information to the data processing center. After processing and analysis, the traffic data generates customized traffic information and sends it to the information display module. The information display module sends its status to the data processing center via the HTTPS interface protocol, facilitating data center management.

[0028] The technical solutions described in the above embodiments can achieve the following:

[0029] At the user level, users can obtain the latest traffic conditions and driving advice through variable message signs. Compared with traditional signs, users can obtain more comprehensive and real-time traffic information in a timely manner.

[0030] On a technical level, the combination of the data processing and analysis module and the intelligent traffic information collection module can effectively process and analyze large amounts of traffic information, improving the efficiency and accuracy of traffic management. The information boards are connected by a mesh network structure, which improves stability and supports communication between them. Therefore, the content to be displayed can be dynamically adjusted based on the content of information boards on adjacent road segments. In the event of a malfunction, even if a particular information board loses its connection to the data center under certain unforeseen circumstances, it can still obtain the latest data information through other information boards.

[0031] At the industry level, the hardware architecture of this invention provides a new solution for intelligent transportation information equipment suppliers, transportation information service providers, and traffic management departments, helping to promote the development of transportation information services. By constructing a mesh network composed of multiple nodes, this system enhances the information acquisition capabilities of the information board system by integrating data collection and analysis equipment on the basis of information dissemination. Utilizing the fusion of communication and data processing technologies, it achieves real-time collection, processing, transmission, and display of highway traffic information.

[0032] The implementation process of this utility model is described below: The information collection module acquires the latest traffic information, including but not limited to GPS location data, traffic camera monitoring data, and traffic data collected by other sensor devices, and transmits this data to the data processing and analysis module. The data processing and analysis module analyzes and processes this real-time data to derive accurate traffic information. It then uses relevant data reduction, fusion, and decision-making algorithms to transform the raw traffic information into customized information such as road conditions or traffic guidance for users or drivers, and distributes the traffic information according to information such as the information board's number.

[0033] While receiving data from the data processing and analysis module, the information display module also sends status information to the data center, facilitating the data center's management and control of the variable message sign array.

[0034] Figure 2 This is a network topology diagram of the system. Each node consists of a display of variable message signs and network devices such as gateways. In this structure, the nodes are relatively equal, with the data center being the computing core of the system, but not necessarily the absolute center of network communication. This approach can reduce the transmission load on the data center. Figure 2This demonstrates a special form of mesh topology—the fully connected type. The advantage of the fully connected type is that any two nodes can communicate, but implementing this scheme is costly. In practical applications, the network can be structured into various shapes according to actual needs. For example, information boards on adjacent road segments can be grouped into a small network, and information can be dynamically adjusted based on the situation of adjacent road segments. Multiple communication channels can be used to improve transmission speed.

[0035] Figure 3 This demonstrates the scenario when a node or line unexpectedly loses connection (e.g., node 1 loses its connection to the data center). Because each node in a mesh network topology is interconnected with at least two other nodes, the disconnected node can reconnect through nearby nodes (e.g., node 2) to obtain data, ensuring service stability. Furthermore, this fault information can be reported to the data processing center via other nodes or paths, facilitating fault location and repair by staff.

[0036] When other variable message signs need to be added to the system network, they do not need to be directly connected to the data processing center. Instead, they only need to be connected to the nearest nodes. Therefore, this structure improves the system's flexibility and scalability.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
