As the most important position for railway passenger transport, high-speed railway passenger stations are required to meet higher standards in technical equipment, passenger transport organization, operation content, staffing and process management to achieve the goal of high-standard refined management.
II. Construction Content
In response to the national development strategy of smart passenger transport, to comprehensively strengthen the on-site operation management of passenger stations, improve and consolidate the management of station junction areas, and realize effective control of operation sites, this solution fully applies advanced management information systems and business platforms to digitize and intellectualize the management methods, objects, processes and evaluation of stations in an all-round way, ensuring the accuracy and effectiveness of management work. Based on the current situation of the station’s production organization such as management system, professional division of labor, organizational structure and operation layout, the Smart Passenger Station Grid Management System takes the station as the main management body, divides the on-site into multiple grid units, and uses advanced and more practical means and technologies to control and implement responsibilities for the operation duties, requirements, processes and content related to each grid unit, so as to improve the quality of daily basic management work of passenger stations.
The system is built to materialize the management philosophy of “transparent information, visual processes, traceable history and predictable future”.
III. Application Scenarios of Project Construction
The Smart Passenger Station Grid Management System mainly provides the following business capabilities:
- Provide graphical and customized management tools for the grid management of stations
- Realize closed-loop operations for all links of patrol inspection and incident handling
- Achieve interconnection and intercommunication of mobile terminals across regions and of multiple types
- Realize dynamic and refined real-time management based on real-time data collection
IV. System Composition
From the perspective of system functions, the Smart Passenger Station Grid Management System can be divided into: Patrol Inspection Subsystem, Incident Disposal Subsystem, Communication Subsystem, Business Data Analysis and Presentation Module, and Extended Business Module.
1. Patrol Inspection Subsystem
The Patrol Inspection Subsystem consists of functional modules such as patrol planning, patrol execution and record query.
Patrol Planning
Grid managers formulate patrol plans through the grid management client (Windows client), assign specific personnel to perform specific tasks in specific grids at specific times, and upload the plans to the system. The system automatically pushes the patrol plans to the grid mobile intelligent terminals of on-site operators.
Patrol Execution
On-site operators conduct patrols in accordance with the patrol plans, and the patrol results are intuitively displayed on the management client. For grids where patrols are not carried out as required, the management client will display them in striking colors on the station layer to prompt managers to handle them in a timely manner.
Record Query
The management client can query patrol records according to various conditions and export the query results.
2. Incident Disposal Subsystem
The Incident Disposal Subsystem is composed of six functional modules forming a closed-loop process: incident reporting, incident assignment, incident acceptance, incident disposal, repair feedback and verification & closure, as well as a record query module.
Incident Reporting
On-site operators initiate incident reporting when finding problems during patrols. Patrol personnel scan the NFC tags of grids or equipment through handheld terminals, fill in problem descriptions and take on-site photos, and report the incidents to the system.
If the problem occurs to equipment affiliated to a specific department, on-site personnel can also extract the detailed information of the equipment from the equipment resume system of the affiliated department through the APP on the handheld intelligent terminal.
Incident Assignment
After receiving the incident report, the system will send the incident to the management client. The management client manually or the system automatically assigns the incident to the affiliated department according to preset conditions; if the affiliated department is a specific department, the incident assignment can be realized through the interface interconnection between the grid management system and the equipment operation and maintenance system of the corresponding department.
Incident Acceptance
Affiliated departments receive incident assignments through the grid incident handling client provided by the system. If the incident is not within the scope of responsibility of the affiliated department, it can be returned. After the affiliated department accepts the incident, its internal equipment operation and maintenance system will handle it in accordance with the established processes.
Incident Disposal
Incidents are disposed of in accordance with the existing systems and processes of the affiliated departments.
Repair Feedback
After handling the incident, the affiliated department feeds back the completion results to the grid management system through the grid incident handling client provided by the system.
Verification & Closure
On-site operators conduct re-inspection of the grids or equipment related to the reported incidents in accordance with the patrol plans. The APP on the handheld terminal will automatically pop up a list to prompt confirmation of whether the incidents of the on-site grids or equipment have been handled. If the on-site incidents are completely handled, the verification & closure process will be executed, and the management client can display the on-site closure status in real time. If it is found that the problems are not resolved, the operator can click “Problem Unresolved”, and the incident will be re-submitted to the relevant affiliated departments for re-execution of the incident handling process.
Record Query
The management client can query incident records according to various conditions and export the query results.
3. Communication Subsystem
(1) Communication Functional Modules
The Communication Subsystem consists of three main functional modules: intercom, voice call and video communication, which are introduced as follows:
- Intercom: On-site operators, the management client and affiliated departments can realize one-to-many half-duplex calls through preset or self-built groups, without geographical restrictions.
- Voice Call: On-site operators, the management client and affiliated departments can make one-to-one full-duplex voice calls with each other.
- Video Communication: The management client can receive real-time video backhaul from on-site operators for a better understanding of on-site conditions.
(2) Application Scenarios of the Communication Subsystem
The main application scenarios of the Communication Subsystem include:
- Realize in-station and cross-station dispatch communication through 4G mobile terminals.
- Realize converged intercom between 4G mobile terminals and traditional analog walkie-talkies, and achieve intercom between public network digital intercom groups and three main existing analog intercom groups (passenger transport group, ticketing group and EMU driver group).
- Realize “one-click switching” intercom for emergency communication, enabling public network digital intercom groups to switch directly to traditional analog intercom groups. In the daily process of organizing passengers to get on and off the train, in case of an emergency that requires an immediate notice for the train to stop, the “SOS button” on the digital terminal can be used to quickly switch to the “driver” group for intercom with the driver.
- The hard intercom function of dual-mode digital terminals can realize intercom between digital terminals and between digital and analog terminals in the case of network disconnection.
- Digital intercom has multi-level permissions: 256-level permissions for communication among group members, with high-level members having the highest speaking permission in the group; different levels of permissions are also set between different intercom groups, with a total of 7-level permissions among groups. When a high-level intercom group speaks, all members of all groups will be connected immediately.
4. Business Data Analysis and Presentation Module
The Business Data Analysis and Presentation Module consists of three main functional modules: business data statistics, trend analysis and GIS display.
- Business Data Statistics: The module collates, analyzes and counts patrol inspection, incident and other data in the business server according to set conditions.
- Trend Analysis: Through the operation trend analysis of statistical results, the module provides scientific, accurate and timely basis for management decision-making for leaders.
- GIS Display: The module displays grid operation statistical data and operation analysis results on the large screens of the monitoring centers of railway bureaus and directly affiliated stations (sections) in a GIS graphical way.
