Protocol converter for unifying control of highway information boards

Abstract

The invention relates to the technical field of protocol converters and in particular to a protocol converter for unifying the control of highway information boards. The protocol converter includes an input communication interface module, an embedded smallest system, a protocol converting module and an output communication interface module. The input communication interface is intended for realizing electrical docking among an Ethernet interface, a serial bus interface and a highway information board device. The embedded smallest system is intended for providing drive programs for the input communication interface module and the output communication interface module, and transmitting the input data to the protocol converting module. The protocol converting module is intended for realizing the conversion between different highway information board communication protocols and the standard communication protocol. The output communication interface module is intended for realizing data docking with information board control systems. According to the invention, the converter realizes unified control of different types of highway information boards, can provide unified interfaces to a plurality of information board control systems, and realizes control of the information boards by a multi-management platform.

Description

technical field [0001] The invention relates to the technical field of protocol converters, in particular to a protocol converter for unified management and control of expressway information boards. Background technique [0002] The expressway information board is widely used in the construction of expressway informatization, providing information such as road conditions and weather conditions for drivers and passengers of passing vehicles. Expressway information board is an electromechanical facility installed in front of expressways and expressway toll stations. Through remote control, it is used to display road-related information (accidents, road maintenance, and bad weather) to guide traffic, so that drivers driving on expressways can make travel routes in real time according to road conditions. [0003] In order to adapt to the use of roads, expressway information boards generally have multiple types, and they come from different manufacturers. Because the electrical ...

Problems solved by technology

[0003] In order to adapt to the use of roads, expressway information boards generally have multiple types, and they come from different manufacturers. Because the electrical interfaces and communication protocols used by different information boards are not the same, each manufacturer has an independent information board release system. The current situation is not conducive to the realization of unified management and control of multiple expressway information boards

The traditional mode uses the electrical interface conversion module. Although the electrical interface is unified, the wiring is complicated, the operation is complicated, it is not easy to install, and the protocol conversion of the multi-information board cannot be realized.
