An Intelligent Gateway Platform Oriented to Expressway Information Board Control System

Abstract

The invention relates to the technical field of highway information board control, and in particular relates to an intelligent gateway platform for a highway information board control system. The intelligent gateway platform comprises an information board information collection and distribution unit and an information board information publishing unit; the information board information collection and distribution unit comprises an Ethernet interface data collection and distribution module, a serial bus interface data collection and distribution module, a first protocol conversion module and a first data communication module; the first protocol conversion module is used for realizing conversion of communication protocols of different highway information boards and standard communication protocols; and the information board information publishing unit comprises a second data communication module, a security module, a second protocol conversion module, a database module and an information publishing module. Because the intelligent gateway platform disclosed by the invention is arranged between the highway information boards and the information board control system, the problem that the highway information boards do not have the unified standard specification can be overcome; and thus, the information board control system publishes information by being networked in a unified manner.

Description

technical field [0001] The invention relates to the technical field of expressway information board control, in particular to an intelligent gateway platform oriented to the expressway information board control system. Background technique [0002] The expressway information board system plays a key role in the release of information such as traffic guidance and safety reminders. In order to standardize the release of information and improve the efficiency of release, the control of the expressway information board is centrally managed. Since there is no uniform standard specification for expressway information boards in China, and there are many manufacturers with different hardware interfaces and software protocols, most manufacturers use their own custom communication protocols, and have not formed a communication protocol that meets the unified standards in the industry. In practical application, the control network of the information boards of the various management off...

AI Technical Summary

Problems solved by technology

[0003] In the current technical application, there are problems such as poor interoperability of network protocols, difficulties in subsequent development, high cost of use and maintenance, unreasonable product structure, over-reliance on manufacturers for development and maintenance, and a large number of new hardware devices, resulting in complex systems, difficult maintenance, and increased investment.

Even so, there are still quite a few occasions where it is difficult to achieve network protocol interoperability and unified release of information, which hinders the development of unified release of expressway information board control system information
