Abstract

The invention discloses a protocol conversion server based on an OPC UA (optical proximity correction unified architecture) standard and an ATS (automatic train supervision) system. The server comprises an information model building unit for building an information model of the ATS system according to information of the automatic train supervision (ATS) system, a dynamic linking library generation unit for leading out the information model of the ATS system to generate a model type library which is compiled to be an ATS model dynamic library, and a protocol conversion unit for converting the ATS model dynamic library from an ATS system protocol into a point list meeting the OPC UA standard through a software development kit SDK of the OPC UA standard according to a preset ATS system protocol analysis library. According to the protocol conversion server based on the OPC UA (optical proximity correction unified architecture) standard and the ATS (automatic train supervision) system, a standardized communication protocol is realized, combination among all systems of a rail transit is facilitated, and intelligence of the rail transit and secure transmission of communication data can be realized favorably.

Description

technical field [0001] The invention relates to the technical field of train monitoring, in particular to a protocol conversion server and an ATS system based on the OPC UA standard. Background technique [0002] The Automatic Train Supervision (ATS) system is a subsystem of the Automatic Train Control (ATC) system, which mainly realizes the supervision and control of trains, and assists dispatchers to manage the trains on the whole line. [0003] The working mode of ATS system is centralized management and decentralized control, and it is a large-scale network distributed system based on LAN communication. The ATS system mainly includes the following subsystems: control center / standby control center subsystem, ATS application server subsystem, signal dedicated gateway subsystem, ATS station extension subsystem, depot extension subsystem, interlocking equipment subsystems of centralized stations on main lines system etc. The Automatic Train Control (ATC) system includes Au...
