Embodiment 1

[0039] Embodiment 1: a kind of construction method of TIAS system real-time database address space, contains the following steps:

[0040] S1. Perform data unit configuration through engineering configuration software;

[0041] Specifically, the engineering configuration software includes four aspects: node deployment, data configuration, graphic configuration, and channel configuration.

[0042] It should be noted that the data unit is the basic unit for organizing the data model. A group of nodes that are functionally related and have a certain degree of geographical independence (for example, one station and one major) are arranged in a "data unit". The files can be binary files or xml files.

[0043] S2. Analyze the configured data unit, and create monitoring objects, IO objects and node objects according to the OPC UA standard;

[0044] S3. Build the monitoring object model according to the relationship between the monitoring objects, build the IO object model according...

Embodiment 2

[0049] Example 2: see Figure 5 , a construction system for the real-time database address space of the TIAS system, including:

[0050] Engineering configuration module 1 is used for data unit configuration; it should be noted that the data unit is the basic unit for organizing the data model. ) is configured in a "data unit", and the files in the data unit can be binary files or xml files.

[0051] Data unit parser 2, used to analyze the configured data unit, and create monitoring objects, IO objects and node objects according to the OPC UA standard;

[0052] The node manager 3 is provided with an address space building module 301 for building a monitoring object model according to the relationship between the monitoring objects using a tree structure, and using a mesh structure to build the IO object model according to the relationship between the monitoring objects. The relationship between objects adopts a hierarchical mechanism to build a node object model;

Abstract

The invention relates to a construction method and system for a real-time database address space of a TIAS system. The construction method comprises the following steps: performing data unit configuration through engineering configuration software; Standardly create monitoring objects, IO objects and node objects; build a monitoring object model according to the relationship between monitoring objects, build an IO object model according to the relationship between IO objects, build a node object model according to the relationship between node objects, and monitor objects The model, the IO object model, and the node object model form an address space. The address space constructed by the invention can effectively improve the data access rate, and avoid the phenomenon of server paralysis or stuck when the database is updated.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to the control technology of rail transit, in particular to a method and system for constructing a real-time database address space of a TIAS system. Background technique [0002] Traffic Control Integrated Automation System (English: Traffic Control Integrated Automation System, referred to as: TIAS) is a set of inter-professional distributed integrated data information platform system. It takes traffic command as the core and integrates ATS, PSCADA, BAS, FAS, UPS, PSD , PIS, PA, ACS, CLK, CCTV, AFC and other businesses are professionally interconnected, integrating and interconnecting professional subsystems closely related to traffic command, and integrating professional business information into a unified traffic command automation platform, so as to make The information of the entire system forms a tightly integrated whole; through a unified human-machine interface, the oper...
