The DSS railway operation dispatching supervision system is generally used in higher-level systems (scheduling centre), including servers, scheduling supervision terminals, engineer stations/system maintenance stations, and display terminals, mainly comprising functions such as dispatching supervision data retrieval, storage, processing, analysis, display, query, alert, system maintenance, and recovery of historical data. From the system status interface, we can directly observe the operating status of the different station equipment below. If a certain station’s equipment encounters any failures, the system interface would show it as an abnormality in that station. The data exchange system shall complete the data exchange between the dispatching supervision slave computer and the dispatching supervision master computer. The train station slave computers include an instruction control unit (ICU), input control module (ICM), input separator plate and data acquirer system, fulfilling the data acquisition, transfer, and sending functions of the station.
The DSS railway transportation and dispatching supervision system’s graphical content can be customised based on the user’s requirements. It displays in real time the data of every station at the dispatching centre, and also displays the station’s semi-automatic data, especially the station’s and inter-station regional data on the big screen of the dispatching centre in real time. In the past, it would be necessary to find out more about the situation at the different stations by making a phone call to the operators on duty at the designation stations, and there was reliance on the scheduler’s familiarity and experience with the company’s railway operating network to carry out train scheduling. However, the introduction of the system changed that. The system operates smoothly, is easy to maintain, is cost-effective, fast and significantly improves work efficiency.
