Problems solved by technology

In the communication process, information needs to be packaged and analyzed in a complex process, which affects communication efficiency
In addition, when the signaling systems of the same section are provided by different suppliers, due to the use of proprietary protocols, the information exchange between systems becomes complicated, and a large number of interface definitions make system development difficult
Moreover, when maintaining and upgrading the system, the use of proprietary protocols creates many obstacles for the completion of these tasks. When adding new interface systems, it is also necessary to design new interface protocols

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] OPC UA technology is a collection of a series of transmission mechanisms and data structure specifications based on Microsoft's COM and DCOM technologies. The emergence of OPC UA technology solves the problem of developing communication interfaces between systems developed by different developers, and saves the design of data structures in system development. At the same time, the security transmission mechanism in OPC UA technology also improves the security of the system.

Abstract

The invention discloses an ATS device and system based on an OPC UA technology and relates to the technical field of train automatic control. The metro ATS device comprises an ATS real-time server, and the ATS real-time server is in communication with a communication front-end processor in a signal system through an OPC UA. An OPC UA standard service interface is utilized to replace an original private protocol; after communication modes of every system are unified, various interfaces do not need defining, and the development cost is reduced; if changes occur in a monitoring system, access can be performed only by conforming to an OPC UA standard, and system expansibility is improved.

Description

technical field [0001] The invention relates to the technical field of automatic train control, in particular to an ATS device and system based on OPC UA technology. Background technique [0002] Automatic Train Supervision System (ATS) is one of the important subsystems of Automatic Train Control System (ATC). It provides a monitoring platform for the subway operation dispatchers to the whole line of trains and on-site signal equipment. Through other signal systems, ATS obtains the real-time status information of on-site signal equipment and train operation, and displays this information to dispatchers, who then issue control instructions according to on-site conditions. In most cases, the ATS system itself will process the obtained real-time status data and generate corresponding automatic control commands. By adopting this automation method, the workload of operation dispatchers can be reduced, and the efficiency and service level of subway operations can be improved. ...
