Data bonding structure and processing method adaptable to metro integrated supervisory control system

Abstract

The invention discloses a data bonding structure adaptable to a metro integrated supervisory control system. A real-time relational database is constructed by an object-oriented technology, each physical device is represented as a data object in the real-time relational database and has a unique ID, the multidimensional characterization of the data object is represented by a series of attributes of the data object, and each attribute has a unique ID; bonding agents are designed according to application needs, an existing structural organization is shielded, boundaries among station data, professional data and data type data are eliminated, from the application needs, data interested by an application are re-arranged into an orderly structure in a data associating way, auxiliary information of the new structure is configured, and finally the most accurate data organization form is presented to an advanced application; meanwhile, a computational aid is preset in each bonding agent, predictable regular logic processing is prepared for the application in advance, and data convenience and logical supporting convenience are provided for the upper-level advanced application to the maximum extent.

Description

technical field [0001] The invention relates to a data bonding structure and a processing method for a real-time comprehensive monitoring and control system in the field of rail transportation such as subways, light rails, monorails, and trams. Background technique [0002] Metro / Light Rail / Monorail / Tram Integrated Supervisory Control System (ISCS Integrated Supervisory Control System) adopts an integrated software and hardware platform and a dedicated communication network to collect information such as power supply system, environment and equipment monitoring system, fire alarm system, signal system, broadcasting system, passenger Information system and other professional real-time data and environmental parameters, and remote control of the operation of each professional system; this inevitably involves the compilation and configuration of thousands of operating equipment and hundreds of thousands of data measuring points, Structural organization and logical application. ...

Problems solved by technology

[0003] Disadvantages of the existing technology: the existing integrated monitoring system database generally carries out data organization according to the unit dimension of "location + specialty + data type", which maintains the mapping consistency with the physical equipment object distribution of the subway line, and the configuration is easy to understand; but as Subway operations have an ever-increasing demand for refined and intelligent equipment and data management. Facing the rising trend of big data correlation extraction and analysis, the existing structure cannot reflect the correlation and interaction between multiple types of equipment and measurement points. This kind of correlation is bound to exist widely in the integrated monitoring system, so when facing more and more new advanced application development and expansion, it often becomes a weakness at the data support level

While thinking about the unique logic of their own application, the developers of each module have to think about how to carry out the secondary organization of data to meet their own program needs while the existing structure remains unchanged; at the same time, many routines can Similar logic codes that are reused are not shared, which increases the difficulty and cycle of development, and additional codes also reduce the efficiency of resource usage
