Front-end processor of rail transit station equipment information based on embedded technology and method

Abstract

The invention relates to a front-end processor of rail transit station equipment information based on embedded technology and a method. The front-end processor is positioned between an upper computer for central monitoring and middle control equipment. The control equipment sends packets according to own communication protocols, and the front-end processor transfers the packets into the uniform communication protocol and provides the standard TCP / IP interface for and outputs the protocol to the upper layer, thus realizing the function of protocol conversion. Configuration data are stored in the front-end processor and the front-end processor can be suitable for different system modes by being provided with configuration serial ports. The invention can more effectively manage the station equipment and the vehicle operation states, ensure the isomeric rail transit station equipment system to be isomorphic, provide bases and standards for network operation and maintenance of the rail transit and promote development of the domestic rail transit.

Description

technical field [0001] The invention belongs to the technical field of rail transit station equipment, and in particular relates to a front-end processor and method for rail transit station equipment information based on embedded technology. Background technique [0002] As an important part of the urban public transportation system, there are currently many types of urban rail transit, such as subways, light rails, suburban railways, trams, and suspension trains, known as "the aorta of urban traffic." At present, my country is in a prosperous period of rail transit construction, and China has become the largest urban rail transit market in the world. [0003] The development prospects of my country's rail transit are broad, but the problems existing in the current rail transit system cannot be ignored. Vehicles, station equipment, and monitoring systems basically use controllers and microcomputer monitoring systems, which involve different equipment and communication proto...

AI Technical Summary

Problems solved by technology

Vehicles, station equipment, and monitoring systems basically use controllers and microcomputer monitoring systems, which involve different equipment and communication protocols from various manufacturers. The system has both network management functions and a high degree of autonomy, so the information collection and data exchange of each system is becoming more complicated

In a modern city, the types of rail transit station equipment are various and intersect with each other, and there are differences in the control systems of various types of equipment. The information between the control systems of different types of equipment cannot be exchanged, and information cannot be effectively shared. If there is a problem with a certain equipment, other equipment control systems cannot get the information immediately, which will definitely delay the time to deal with the problem, and even cause further expansion of the damage

It can be seen that the operation mode brought about by the construction mode of the separate line equipment control system has brought great obstacles to the construction, operation and safety of rail transit
