Technical Field

[0001] This invention relates to the field of intelligent transportation technology, and in particular to an intelligent transportation information display system and method based on multi-protocol adaptive design. Background Technology

[0002] With the development of intelligent transportation, traffic information display systems (such as LED information boards and highway lane indicator devices) have been widely used. However, existing traffic information display systems typically have the following shortcomings: 1. Poor protocol compatibility: Most systems only support one specific protocol; 2. Rigid information processing mechanism: It generally only supports one communication method, such as TCP / UDP / serial port, for interacting with external devices; 3. Weak device collaboration capability: In a large-scale deployment environment, it is difficult to achieve unified management and collaborative work among devices; 4. Insufficient fault recovery capability: There is a lack of automatic switching and recovery mechanisms when the communication link is interrupted, making it difficult to troubleshoot equipment failures. 5. Complex configuration management: Changes to the display area configuration require system downtime for maintenance, affecting system availability. Summary of the Invention

[0003] This invention provides an intelligent traffic information display system and method based on multi-protocol adaptive design, aiming to solve the problems of protocol incompatibility, decentralized management, low level of intelligence, and low operation and maintenance efficiency in existing traffic information display systems.

[0004] This invention provides a multi-protocol adaptive intelligent traffic information display system, comprising: Multiple traffic information display devices: The multiple traffic information display devices are interconnected via communication. Protocol Adaptive Module: The protocol adaptive module has a built-in data processing module for multiple communication protocols. When external configuration data is received, the module parses the configuration data according to the communication protocol that the configuration data conforms to, and obtains the display content. Intelligent scheduling module: used to prioritize displayed content based on its type; Command issuance and display module: used to issue the display content to the multiple traffic information display devices and display them according to the priority order.

[0008] As a further improvement of the present invention, the traffic information display device supports at least one of the following connection methods: serial port, TCP server, TCP client, UDP, and TCP serial port pass-through mode.

[0009] As a further improvement of the present invention, when the traffic information display device is working in TCP serial port pass-through mode, if the received data does not conform to any of its built-in standard protocol formats, the data is passed through the serial port to another serially connected traffic information display device.

[0010] To achieve the above objectives, the present invention also proposes an intelligent traffic information display method based on multi-protocol adaptation, the method comprising the following steps: Step S10: After receiving the external configuration data, the configuration data is parsed according to the communication protocol conforming to the configuration data to obtain the display content; Step S20: Prioritize the displayed content according to its type; Step S30: The display content is sent to the multiple traffic information display devices and displayed according to the priority order.

[0012] As a further improvement of the present invention, step S10 further includes: If the received data does not conform to any of its built-in standard protocol formats, the data will be passed through the serial port to another connected traffic information display device.

[0013] As a further improvement of the present invention, the method further includes: receiving status information of the plurality of traffic information display devices, periodically monitoring the functional status of the plurality of traffic information display devices, and performing a self-healing operation when an abnormality is detected.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] This invention proposes an intelligent traffic information display system based on multi-protocol adaptive technology, such as... Figure 1 As shown, a preferred embodiment of the intelligent traffic information display system based on multi-protocol adaptation of the present invention includes multiple traffic information display devices and a control system that is communicatively connected to the multiple traffic information display devices. The control system includes a protocol adaptation module, an intelligent scheduling module, and an instruction issuance and display module.

[0022] The multiple traffic information display devices are interconnected via communication. These devices communicate with each other using an internal protocol within the same network segment, and can interactively control each other based on data content.

[0023] The protocol adaptation module has a built-in data processing module for multiple communication protocols. When external configuration data is received, the module parses the configuration data according to the communication protocol it conforms to, and then obtains the display content.

[0024] The communication protocols include the LED information board variable information sign communication protocol and the highway system lane equipment interface specification.

[0025] Intelligent scheduling module: used to prioritize displayed content based on its type.

[0026] In this embodiment, the intelligent scheduling module classifies the displayed content, such as into accidents, severe weather, etc. After the intelligent scheduling module obtains the parsed displayed content, it will prioritize the displayed content according to its type, and display the content with higher priority first.

[0027] Command issuance and display module: used to issue the display content to the multiple traffic information display devices and display them according to the priority order.

[0028] This embodiment achieves automatic identification and parsing of multiple protocol data through the "protocol adaptive module," enabling a single control system to manage various heterogeneous devices and breaking down protocol barriers. The "intelligent scheduling module" implements dynamic priority sorting based on displayed content, ensuring that high-priority information such as traffic accidents and severe weather is displayed first and in a timely manner, thereby improving the response efficiency and intelligence level of the entire traffic management system.

[0029] Furthermore, in this embodiment, the intelligent traffic information display system based on multi-protocol adaptation also includes a device status monitoring and fault self-healing module, which is used to receive the status information of the multiple traffic information display devices, monitor the functional status of the multiple traffic information display devices at regular intervals, and perform self-healing operations when an abnormality is detected.

[0030] In this embodiment, the device status monitoring and fault self-healing module can be used to periodically detect the functions of various modules of the traffic information display device, such as the device's 4G communication module, and will attempt to restart the traffic information display device after detecting an abnormality.

[0031] In this embodiment, the intelligent traffic information display system based on multi-protocol adaptation further includes a dynamic configuration management module. This module dynamically switches the communication protocol used by the protocol adaptation module based on received external configuration data during system operation, without requiring a system or device restart. Therefore, this embodiment solves the technical problem of requiring a system shutdown and restart when updating or switching communication protocols (such as upgrading protocol versions or connecting new vendor equipment), leading to interruptions in traffic information services. It achieves the system's "hot update" capability. It allows for the dynamic loading of new protocol parsing modules or switching of protocol configurations without interrupting existing services, ensuring the continuity and high availability of traffic information publishing services. This is crucial for a 24 / 7 traffic management system, significantly improving system maintainability and flexibility.

[0032] Furthermore, in this embodiment, the traffic information display device supports at least one connection method among serial port, TCP server, TCP client, UDP, and TCP serial port pass-through mode.

[0033] When a traffic information display device operates in TCP serial port pass-through mode, if the received data does not conform to any of its built-in standard protocol formats, the data will be pass-through to another connected traffic information display device via the serial port. In this way, other devices that do not use this protocol can still be bridged and extended on the current device. For example, in TCP serial port pass-through mode, if device B is connected to device A via a serial port, after device A receives data from the control system, if the data content is not in the currently configured protocol format, it can pass the data through the serial port to device B, thereby achieving the control purpose.

[0034] The invention will now be described in conjunction with specific application scenarios.

[0035] Scenario 1: Highway Integrated Control Center Application scenario: Managing hundreds of different types of information display devices.

[0036] Technical Implementation Solution: Large information boards use the TCP protocol; The toll booth equipment is connected via a serial port; The electric barrier device uses UDP communication.

[0037] Technical benefits: A unified platform manages all devices, reducing operational and maintenance complexity.

[0038] Scenario 2: Severe Weather Emergency Response: Application scenario: Traffic safety management under extreme weather conditions such as heavy fog and rainstorms.

[0039] Technical Implementation Solution: LED information board equipment connects to sensors such as temperature and humidity, and acquires real-time weather data to activate an emergency information insertion mechanism, coordinating multiple devices to display warning information simultaneously.

[0040] Technical effect: Improves the timeliness and effectiveness of traffic information transmission in severe and difficult conditions.

[0041] Scenario 3: Transportation support for major events: Application scenario: Traffic control during large-scale events, conferences, and other activities.

[0042] Technical Implementation Solution: Preset display template for the event period; Dynamically update route guidance information; Enables collaborative operation of equipment across different road sections; Technical benefits: Provides efficient information dissemination methods to ensure the smooth running of events.

[0043] The beneficial effects of the multi-protocol adaptive intelligent traffic information display system of this invention are: 1. Strong protocol compatibility: One system can support multiple vendors' devices that follow different industry standard protocols, which greatly reduces the deployment and integration costs of the system.

[0044] 2. Intelligent information processing: Through a dynamic priority scheduling mechanism, key traffic information such as accidents and severe weather can be displayed in a timely manner, thereby improving the emergency response capability of traffic management.

[0045] 3. High system reliability: It has the ability to self-diagnose and self-heal equipment faults, as well as a load balancing mechanism, which effectively improves the stability and availability of the entire display system.

[0046] 4. Improved operation and maintenance efficiency: Supports dynamic updating of protocol configuration at runtime without downtime and restart, reducing system downtime and operation and maintenance complexity.

[0047] 5. Excellent scalability: It adopts a modular design and is compatible with non-standard equipment through serial port pass-through and other modes, which facilitates the addition of new functional modules and the connection of new equipment in the future, and adapts to the continuous development needs of intelligent transportation.

[0048] To achieve the above objectives, this invention also proposes a multi-protocol adaptive intelligent traffic information display method, such as... Figure 2 As shown, a preferred embodiment of the intelligent traffic information display method based on multi-protocol adaptation of the present invention includes the following steps: Step S10: After receiving the external configuration data, the configuration data is parsed according to the communication protocol conforming to the configuration data to obtain the display content.

[0049] The communication protocols include the LED information board variable information sign communication protocol and the highway system lane equipment interface specification.

[0050] Step S20: Prioritize the displayed content according to its type.

[0051] In this embodiment, the displayed content is classified, such as accidents, severe weather, etc. After the intelligent scheduling module obtains the parsed displayed content, it will prioritize the displayed content according to its type and display the content with higher priority.

[0052] Step S30: The display content is sent to the multiple traffic information display devices and displayed according to the priority order.

[0053] This embodiment achieves automatic identification and parsing of multiple protocol data, enabling a single control system to manage various heterogeneous devices and breaking down protocol barriers; it also implements dynamic priority sorting based on display content, ensuring that high-priority information such as traffic accidents and severe weather can be displayed first and in a timely manner, thereby improving the response efficiency and intelligence level of the entire traffic management system.

[0054] Step S10 specifically includes: Step S101: Dynamically switch the communication protocol used by the protocol adaptation module according to the received external configuration data, without restarting the system or device.

[0055] Therefore, this embodiment solves the technical problem of system downtime and restart required when updating or switching communication protocols (such as upgrading protocol versions or connecting new vendor equipment), which leads to interruptions in traffic information services. It achieves the system's "hot update" capability. This allows for the dynamic loading of new protocol parsing modules or switching of protocol configurations without interrupting existing services, ensuring the continuity and high availability of traffic information publishing services. This is crucial for a 24 / 7 traffic management system, significantly improving system maintainability and flexibility.

[0056] Step S10 further includes: If the received data does not conform to any of its built-in standard protocol formats, the data will be passed through the serial port to another connected traffic information display device.

[0057] Thus, devices that are not compatible with this protocol can still be bridged onto the current device for extended use. For TCP serial port pass-through mode, for example, if device B is connected to device A via a serial port, after device A receives data from the control system, if the data content is not in the currently configured protocol format, it can pass the data through the serial port to device B, thereby achieving the control purpose.

[0058] In this embodiment, the method further includes: receiving status information of the plurality of traffic information display devices, periodically monitoring the functional status of the plurality of traffic information display devices, and performing a self-healing operation when an abnormality is detected.

[0059] In this embodiment, the functions of each module of the traffic information display device, such as the device's 4G communication module, can be detected periodically. If an abnormality is detected, the device will be restarted.

[0060] The beneficial effects of the multi-protocol adaptive intelligent traffic information display method of this invention are: 1. Strong protocol compatibility: One system can support multiple vendors' devices that follow different industry standard protocols, which greatly reduces the deployment and integration costs of the system.

[0061] 2. Intelligent information processing: Through a dynamic priority scheduling mechanism, key traffic information such as accidents and severe weather can be displayed in a timely manner, thereby improving the emergency response capability of traffic management.

[0062] 3. High system reliability: It has the ability to self-diagnose and self-heal equipment faults, as well as a load balancing mechanism, which effectively improves the stability and availability of the entire display system.

[0063] 4. Improved operation and maintenance efficiency: Supports dynamic updating of protocol configuration at runtime without downtime and restart, reducing system downtime and operation and maintenance complexity.

[0064] 5. Excellent scalability: It adopts a modular design and is compatible with non-standard equipment through serial port pass-through and other modes, which facilitates the addition of new functional modules and the connection of new equipment in the future, and adapts to the continuous development needs of intelligent transportation.
