Embodiment 1

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

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

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

[0042] It should be noted that a data unit is the basic unit of an organizational data model, and a group of nodes that are functionally related and geographically independent (such as a station and a profession) are configured in a "data unit". The file can be a binary file or an xml file.

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

[0044] S3. Construct the monitoring object model according to the relationship between the monitoring objects, construct the IO object model accord...

Embodiment 2

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

[0050] Engineering configuration module 1 is used for data unit configuration; it should be noted that a data unit is the basic unit of an organizational data model, and a group of nodes that are functionally related and have a certain degree of ) are 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 construction module 301, which is used to construct a monitoring object model using a tree structure according to the relationship between the monitoring objects, and constructing an IO object model using a network structure according to the relationship between the IO objects. The relatio...

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; analyzing the configured data unit, and creating a monitoring object, an IO object and a node object according to an OPC UA standard; a monitoring object model is constructed according to the relation between the monitoring objects, an IO object model is constructed according to the relation between the IO objects, a node object model is constructed according to the relation between the node objects, and the monitoring object model, the IO object model and the node object model form an address space. According to the address space constructed by the method, the data access rate can be effectively improved, and the phenomenon that the server is paralyzed or stuck when the database is updated is avoided.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a rail transit traffic control technology, in particular to a method and a 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, which takes traffic command as the core and integrates ATS, PSCADA, BAS, FAS, UPS, PSD , PIS, PA, ACS, CLK, CCTV, AFC and other business professional interconnections, integrated and interconnected professional subsystems closely related to traffic command, and incorporated various professional business information into a unified traffic command automation platform for organic integration, so that The information of the entire system forms a tightly integrated whole; through a unified human-...
